Explanations
- 1. floor
- 'No, I don't have any, but the floor would need cleaning.' 'Of course – we'd do that in every room.' 'In every room' is the note's 'throughout the apartment'.Common trap: Carpets are what Jacinta asks about, and the client's 'I don't have any' can be mistaken for the answer to the wrong question.
- 2. fridge
- 'Actually, I hardly ever use that, but can you do the fridge?' 'Sure. Would you like that done every week?' 'Yes, definitely.'Common trap: The oven is offered first and turned down, and the microwave is offered later and also refused — only the fridge is agreed.
- 3. shirts
- 'It wouldn't be much, just my shirts for work that week.' 'Just … only' is what the note records.Common trap: 'For work' follows the answer and is a tempting one-word fit for the gap after 'ironing clothes –'.
- 4. windows
- 'If the inside of your windows need cleaning, we could do that.' 'Yes, that'd be good … the outside gets done regularly by specialists, but the inside does get a bit grubby.'Common trap: Curtains are offered next and refused, and the outside window cleaning is done by other specialists — the note is specifically the inside.
- 5. balcony
- 'But would you be able to do something about the balcony? … it could do with a wash every month or so.' 'Yes, we can get the pressure washer onto that.'Common trap: The request comes from the client and the reply names only the equipment — 'the pressure washer' — not the place.
- 6. electrician
- 'If you have a problem with water and you need a plumber in a hurry, we can put you in touch with a reliable one … And the same thing if you need an electrician.'Common trap: The plumber gets a full sentence of explanation and is already printed in the note, so the second trade is delivered in a five-word add-on.
- 7. dust
- 'We also offer a special vacuum cleaning system which can improve the indoor air quality of your home by capturing up to 99% of all the dust in the air. So if you're troubled by allergies, this can make a big difference.'Common trap: 'Indoor air quality' and 'allergies' frame the sentence, so the specific substance is easy to skip over in the middle of a percentage claim.
- 8. police
- 'When they apply to us, they have to undergo a security check with the police to make sure they don't have any sort of criminal background.'Common trap: 'Security check' and 'criminal background' are the memorable phrases, and the body carrying out the check is one word in the middle.
- 9. training
- 'If we think they might be suitable for the job, we give them training for it. That lasts for two weeks so it's very thorough, and at the end of it, they have a test.'Common trap: The test at the end of the fortnight is what the passage builds to, but the note asks for what fills the two weeks.
- 10. review
- 'We ask all our clients to complete a review of their performance after every visit and to email it to us.'Common trap: The word sits inside a long sentence about monitoring, with 'performance' immediately after it as a plausible alternative.
- 11. a lack of training.
- 'A lot of managers think it's this and the long hours that are the main causes of high staff turnover – but what they don't realise is that it's the lack of training in many hotel jobs which is a huge factor.'Common trap: All three options are true causes; the question asks which one managers are unaware of, and 'what they don't realise' is the only marker.
- 12. an increased workload
- 'Having to recruit new staff all the time can be very time-consuming, and managers may have to cover some duties while waiting for new staff to arrive.'Common trap: Morale is discussed two sentences later and belongs to the colleagues left behind — the question is specifically about managers.
- 13. failing to treat staff equally
- 'When organising shifts, for example, make sure you never give certain staff preferential treatment … everyone should have to work some evening and weekend shifts.'Common trap: Shifts and busy periods both appear in the same short paragraph, so the mistake has to be separated from the setting in which it happens.
- 14. a rise in spending per customer
- 'Not only did the level of complaints fall, but they also noticed a significant increase in the amount each customer spent during their stay.' The 'not only … but also' marks the second one as the extra benefit.Common trap: Three outcomes in two sentences — the intended one, the unexpected one, and a later initiative. Only the middle one answers 'unexpected benefit'.
- 15. A
- Staff felt managers didn't value their opinions or treat them as partners; now 'junior staff at all levels are regularly invited to meetings where their ideas are welcomed'. That is improving relationships and teamwork (A).Common trap: 'Contributing to the success of the business' sounds like a career or incentive scheme — the change is about inclusion in decisions.
- 16. C
- 'Their first step was to introduce a scheme for recognising talent amongst their employees … organising training for individuals with management potential will encourage them to stay.' Career opportunities (C).Common trap: 'Recognising talent' can read as a reward scheme, but what is offered is management training, not money.
- 17. B
- 'As a reward, they're sent on an all-expenses-paid trip abroad every year.' A paid trip is a financial benefit (B).Common trap: The trip includes learning — a brewery visit and product knowledge — which pulls towards the career-development option.
- 18. C
- 'They introduced a management programme. These staff were given additional responsibilities and the chance to work in various roles in the hotel.' Career opportunities (C).Common trap: 'Worthwhile and rewarding' appears in the run-up and sounds financial, but the reward described is prospects and varied roles.
- 19. B
- 'The hotel began issuing vouchers to help cover the cost of childcare.' Vouchers with a cash value are a financial benefit (B).Common trap: 'Wanted to be seen as a caring employer' opens the item and points at the relationships option — the action itself is financial help.
- 20. A
- 'She has made a huge effort to achieve this by creating a co-operative and supportive environment. For her, the staff are part of a large family where everyone is valued.'Common trap: The final item has no scheme or programme at all — the answer rests entirely on the words describing the atmosphere.
- 21. He could have worked harder at them.
- 'Perhaps they should have pushed me harder, though … I think I should have practised more.'Common trap: Parents are mentioned twice — as not pushing him and as proud of him — which is close to option D but not the same as disappointment.
- 22. His fellow students admired him.
- 'That was my goal, and all my classmates assumed I would achieve it; they thought I was brilliant.'Common trap: His own confidence — 'I thought I could win anything' — follows immediately and is easy to credit to option A instead.
- 23. disbelief
- 'I thought "this can't be happening"! I was used to winning.' That is disbelief at not being good enough.Common trap: 'So calm about it' rules out stress explicitly, and the pride of people back home is not one of his own feelings.
- 24. gratitude
- 'I just kept thinking how fortunate I was. What a great chance this was!' Feeling fortunate about the opportunity is gratitude.Common trap: The word 'gratitude' never appears — 'how fortunate I was' has to be recognised as the same feeling.
- 25. B
- 'In about the 1920s, a factory was making rolls of the rubber in bulk for something like horse harnesses' — and someone realised it would cover the wooden bats. The material was mass produced for another purpose (B).Common trap: The wooden bats are mentioned either side of the answer, which invites a material-cost or make-your-own reading instead.
- 26. F
- 'When the first cricket helmet came in, in 1978, the Australian batsman who first wore it was booed and jeered by people watching because it was so ugly!' Booing spectators is option F.Common trap: Protection from injury is discussed in the next line, which makes the injuries option tempting — but the helmet prevented injuries rather than causing them.
- 27. A
- 'It says serious cyclists ended up with wet hair from all the hard exercise' — and Jeanne explains that modern helmets have air vents 'so that the skin can breathe more easily'. Excessive sweating (A).Common trap: The ugly upside-down-bowl design and the proud woman in the photo suggest the unpopularity options, but the comment recorded is the sweating.
- 28. D
- 'Because a club was made entirely of wood, it would easily break and players had to get another.' Frequent replacement (D).Common trap: The material is the cause, which makes the material-based options attractive — but the comment is about what kept happening as a result.
- 29. C
- 'What it does say here, though, is that when the game started you had to produce a stick yourself.' Making your own (C).Common trap: Thomas assumes hockey sticks changed like golf clubs, and Jeanne corrects him — wooden sticks are still used, so the replacement option does not apply here.
- 30. G
- The leather balls let in water and became heavier: 'You can imagine the damage to player's necks when the ball was headed.' The equipment caused injuries (G).Common trap: Animal skin, leather and stitching all appear first and point at the material options — the comment that matters is the consequence of the water-logged ball.
- 31. golden
- 'Maple syrup is a thick, golden, sweet-tasting liquid that can be bought in bottles or jars.'Common trap: 'Looks rather like clear honey' comes earlier and is a comparison, not the colour word the note wants.
- 32. healthy
- 'It contains no preservatives or added ingredients, and it provides a healthy alternative to refined sugar.'Common trap: 'Natural' is used twice about the product earlier in the paragraph and fits the gap just as well — but the word paired with 'refined sugar' is the one required.
- 33. climate
- 'There are only certain parts of the world that provide all these conditions: one is Canada … and the other is the north-eastern states of North America. In these areas, the climate suits the trees perfectly.'Common trap: 'Conditions' is already printed in the note and is repeated several times in the talk — the new word comes in the short summarising sentence.
- 34. rock
- 'They boiled the liquid by placing pieces of rock that had become scorching hot from the sun into the sap.'Common trap: 'The sun' is what made them hot and is the last noun before 'into the sap' — the thing actually placed in the liquid is the rock.
- 35. diameter
- 'They cannot be used to make syrup until the trunks reach a diameter of around 25 centimetres. This can take anything up to 40 years.'Common trap: Two numbers frame the answer — 25 centimetres and 40 years — and the note already contains the second one.
- 36. tube
- 'This involves drilling a small hole into the trunk and inserting a tube into it that ends in a bucket.'Common trap: 'Hole', 'trunk' and 'bucket' are all in the same clause and all appear in the note already — the only new word is the connector.
- 37. fire
- 'These are basically extremely large pans – the sap is poured into these, a fire is built and the pans are then heated until the sap boils.'Common trap: 'Evaporators' and 'boils' dominate the sentence, and the heat source is a three-word clause in the middle of the process description.
- 38. steam
- 'The evaporation process creates large quantities of steam, and the sap becomes thicker and denser.'Common trap: The syrup forming and the sap thickening are described either side of it, so the by-product is easy to pass over.
- 39. cloudy
- '"Sugar sand" has to be filtered out as this builds up during the boiling and gives the syrup a cloudy appearance and a slightly gritty taste.'Common trap: 'Gritty' sits in the same clause and describes the taste, which the note mentions separately — the gap needs the appearance word.
- 40. litre
- 'It takes 40 litres of sap to produce one litre of maple syrup so you can get an idea of how much is needed!'Common trap: The same unit appears twice in one sentence, once for the sap and once for the syrup — the note asks for the measure of the finished product.

Part 1 — A phone call about a domestic cleaning service
JACINTA: Hello, Easy Life Cleaning Services, Jacinta speaking. CLIENT: Oh hello. I’m looking for a cleaning service for my apartment – do you do domestic cleaning? JACINTA: Sure. CLIENT: Well, it’s just a one-bedroom flat. Do you have a basic cleaning package? JACINTA: Yes. For a one-bedroom flat we’re probably looking at about two hours for a clean. So we’d do a thorough clean of all surfaces in each room, and polish them where necessary. Does your apartment have carpets? CLIENT: No, I don’t have any, but the floor would need cleaning. JACINTA: Of course – we’d do that in every room. And we’d do a thorough clean of the kitchen and bathroom. CLIENT: OK. JACINTA: Then we have some additional services which you can request if you want – so for example, we can clean your oven for you every week. CLIENT: Actually, I hardly ever use that, but can you do the fridge? JACINTA: Sure. Would you like that done every week? CLIENT: Yes, definitely. And would ironing clothes be an additional service you can do? JACINTA: Yes, of course. CLIENT: It wouldn’t be much, just my shirts for work that week. JACINTA: That’s fine. And we could also clean your microwave if you want. CLIENT: No, I wipe that out pretty regularly so there’s no need for that. JACINTA: We also offer additional services that you might want a bit less often, say every month. So for example, if the inside of your windows need cleaning, we could do that. CLIENT: Yes, that’d be good. I’m on the fifteenth floor, so the outside gets done regularly by specialists, but the inside does get a bit grubby. JACINTA: And we could arrange for your curtains to get cleaned if necessary. CLIENT: No, they’re OK. But would you be able to do something about the balcony? It’s quite small and I don’t use it much, but it could do with a wash every month or so. JACINTA: Yes, we can get the pressure washer onto that. JACINTA: Now if you’re interested, we do offer some other possibilities to do with general maintenance. For example, if you have a problem with water and you need a plumber in a hurry, we can put you in touch with a reliable one who can come out straightaway. And the same thing if you need an electrician. CLIENT: Right. That’s good to know. I’ve only just moved here so I don’t have any of those sorts of contacts. JACINTA: And I don’t know if this is of interest to you, but we also offer a special vacuum cleaning system which can improve the indoor air quality of your home by capturing up to 99% of all the dust in the air. So if you’re troubled by allergies, this can make a big difference. CLIENT: Right. In fact, I don’t have that sort of problem, but I’ll bear it in mind. Now can you tell me a bit about your cleaning staff? JACINTA: Of course. So all our cleaners are very carefully selected. When they apply to us, they have to undergo a security check with the police to make sure they don’t have any sort of criminal background, and, of course, they have to provide references as well. Then if we think they might be suitable for the job, we give them training for it. That lasts for two weeks so it’s very thorough, and at the end of it, they have a test. If they pass that, we take them on, but we monitor them very carefully – we ask all our clients to complete a review of their performance after every visit and to email it to us. So we can pick up any problems straightaway and deal with them. CLIENT: OK, well that all sounds good. And will I always have the same cleaner? JACINTA: Yes, we do our best to organise it that way, and we usually manage it. CLIENT: Good. That’s fine. Right, so I’d like to go ahead and …
Part 2 — A talk on reducing staff turnover in hotels
As many of you here today have worked in the hotel industry for some time, I’m sure you have experienced the problem of high staff turnover in your hotels. Every hotel relies on having loyal and experienced members of staff who make sure that everything runs smoothly. If staff are constantly changing, it can make life difficult for everyone. But why do staff leave frequently in many hotels? Of course, many hotel jobs, such as cleaning, are low-skilled and are not well-paid. A lot of managers think it's this and the long hours that are the main causes of high staff turnover – but what they don’t realise is that it’s the lack of training in many hotel jobs which is a huge factor. So, what kind of problems does a high turnover of staff cause? Well, having to recruit new staff all the time can be very time-consuming, and managers may have to cover some duties while waiting for new staff to arrive. This means they don’t have time to think about less immediate problems such as how to improve their service. When staff leave, it can also severely affect the colleagues they leave behind. It has a negative effect on remaining staff, who may start to feel that they too should be thinking about leaving. So, what can be done to change this situation? Firstly, managers should stop making basic errors which leave their staff feeling upset and resentful. When organising shifts, for example, make sure you never give certain staff preferential treatment. All staff should be given some choice about when they work, and everyone should have to work some evening and weekend shifts. If you treat staff fairly, they’ll be more likely to step in and help when extra staff are needed. Keeping staff happy has other tangible benefits for the business. Take the Dunwich Hotel as an example. It had been experiencing a problem with staff complaints and in order to deal with this, invested in staff training and improved staff conditions. Not only did the level of complaints fall, but they also noticed a significant increase in the amount each customer spent during their stay. They have now introduced a customer loyalty scheme which is going really well. Now I’d like to look at some ways you can reduce staff turnover in your hotels, and I’ll do this by giving some examples of hotels where I’ve done some training recently. The Sun Club received feedback which showed that staff thought managers didn’t value their opinions. They weren’t made to feel they were partners who were contributing to the success of the business as a whole. This situation has changed. Junior staff at all levels are regularly invited to meetings where their ideas are welcomed. A year ago, The Portland recognised the need to invest in staff retention. Their first step was to introduce a scheme for recognising talent amongst their employees. The hope is that organising training for individuals with management potential will encourage them to stay with the business. At Bluewater, managers decided to recognise 50 high achievers from across the company’s huge hotel chain. As a reward, they’re sent on an all-expenses-paid trip abroad every year. Fun is an important element in the trips, but there’s also the opportunity to learn something useful. This year’s trip included a visit to a brewery, where staff learned about the new beer that would be served in the hotel. Pentlow Hotels identified that retention of junior reception staff was an issue. In order to encourage them to see that working in a hotel could be worthwhile and rewarding, with good prospects, they introduced a management programme. These staff were given additional responsibilities and the chance to work in various roles in the hotel. Green Planet wanted to be seen as a caring employer. To make life easier for staff, many of whom had childcare responsibilities, the hotel began issuing vouchers to help cover the cost of childcare. Louise Marsh at The Amesbury has one of the best staff retention rates in the business. Since she joined the company, she has made a huge effort to achieve this by creating a co-operative and supportive environment. For her, the staff are part of a large family where everyone is valued. OK, now I’d like to …
Part 3 — Two students discussing sport and equipment design
JEANNE: Hi Thomas, how are you enjoying the course so far? THOMAS: Yeah, I think it’s good. JEANNE: Remind me – why did you decide to study sports science? Didn’t you want to be a professional athlete when you were at school? THOMAS: Yeah – that was my goal, and all my classmates assumed I would achieve it; they thought I was brilliant. (Q21/22) JEANNE: That must have been a nice feeling. THOMAS: Mm, I thought I could win anything. There was no one who could run faster than me. JEANNE: Exactly – so what happened? Did your mum and dad want you to be more ‘academic’? THOMAS: Not at all. Perhaps they should have pushed me harder, though. (Q21/22) JEANNE: What do you mean? THOMAS: I think I should have practised more. JEANNE: What makes you say that? THOMAS: Well, I went out to Kenya for a couple of weeks to train … JEANNE: Really! I didn’t know that. THOMAS: I was chosen to go there out of loads of kids and run with some of the top teenage athletes in the world. And … I was so calm about it. I just kept thinking how fortunate I was. What a great chance this was (Q23/24)! Everyone back home was so proud of me. But once we started competing, I very quickly realised I wasn’t good enough. JEANNE: That must have been a huge shock. THOMAS: I thought ‘this can’t be happening’ (Q23/24)! I was used to winning. JEANNE: I’m sorry to hear that. THOMAS: It’s OK. I’m over it now and I think it’s much better to do a university course and this one has such a variety of sports-related areas. It’s going to be good. JEANNE: Oh, I agree – I chose it because of that. THOMAS: So Jeanne – have you thought of any ideas for the discussion session next week on technology and sport? JEANNE: We have to cover more than one sport, don’t we? THOMAS: Yeah. JEANNE: You know – we always think technology is about the future, but we could gather some ideas about past developments in sport. THOMAS: Look at early types of equipment perhaps? Uh, I remember reading something about table tennis bats once – how they ended up being covered with pimpled rubber. JEANNE: Cos they were just wooden at first, I’d imagine. THOMAS: Yeah. In about the 1920s, a factory was making rolls of the rubber in bulk for something like horse harnesses. JEANNE: Really! THOMAS: Yeah – and someone realised that it’d make a perfect covering for the wooden bats. JEANNE: So what about cricket – that’s had a few innovative changes. Maybe the pads they were on their legs? THOMAS: I don’t think they’ve changed much but, I’m just looking on the internet … and it says that when the first cricket helmet came in, in 1978, the Australian batsman who first wore it was booed and jeered by people watching because it was so ugly! JEANNE: Wow, players have to protect themselves from getting hurt! I mean everyone wears one now. THOMAS: Mm, unlike the cycle helmet. JEANNE: Well, unless you’re a professional, but you’re right, many ordinary bikers don’t wear a helmet. THOMAS: Hey, look at these pictures of original helmet designs. This one looks like an upside-down bowl! JEANNE: Yet, the woman’s laughing – she’s so proud to be wearing it! THOMAS: It says serious cyclists ended up with wet hair from all the hard exercise. JEANNE: I guess that’s why they have large air vents in them now so that the skin can breathe more easily. THOMAS: OK, so we’ve done helmets. What about golf balls or better still golf clubs – they’ve changed a lot. JEANNE: Yeah – I remember my great grandfather telling me that because a club was made entirely of wood, it would easily break and players had to get another. THOMAS: There’s no wood at all in them now, is there? JEANNE: No – they’re much more powerful. THOMAS: The same must be true of hockey sticks. JEANNE: I don’t think so because players still use wooden sticks today. What it does say here, though, is that when the game started you had to produce a stick yourself. THOMAS: I guess they just weren’t being manufactured. So, one more perhaps. What about football? JEANNE: Well, I know the first balls were made of animal skin. THOMAS: Yeah, they covered them with pieces of leather that were stitched together, but … the balls let in water when it rained. JEANNE: Oh, that would have made them much heavier. THOMAS: That’s right. You can imagine the damage to player’s necks when the ball was headed. JEANNE: How painful that must have been! THOMAS: Yeah, well, I think we can put together some useful ideas …
Part 4 — A lecture on maple syrup
Hello everyone. Today we’re going to look at another natural food product and that’s maple syrup. What is this exactly? Well, maple syrup looks rather like clear honey, but it’s not made by bees; it’s produced from the plant fluid – or sap – inside the maple tree and that makes maple syrup a very natural product. Maple syrup is a thick, golden, sweet-tasting liquid that can be bought in bottles or jars and poured onto food such as waffles and ice cream or used in the baking of cakes and pastries. It contains no preservatives or added ingredients, and it provides a healthy alternative to refined sugar. Let’s just talk a bit about the maple tree itself, which is where maple syrup comes from. So, there are many species of maple tree, and they’ll grow without fertilizer in areas where there’s plenty of moisture in the soil. However, they’ll only do this if another important criterion is fulfilled, which is that they must have full or partial sun exposure during the day and very cool nights – and I’ll talk more about that in a minute. There are only certain parts of the world that provide all these conditions: one is Canada, and by that, I mean all parts of Canada, and the other is the north-eastern states of North America. In these areas, the climate suits the trees perfectly. In fact, Canada produces over two-thirds of the world’s maple syrup, which is why the five-pointed maple leaf is a Canadian symbol and has features on the flag since 1964. So how did maple syrup production begin? Well, long before Europeans settled in these parts of the world, the indigenous communities had started producing maple sugar. They bored holes in the trunks of maple trees and used containers made of tree bark to collect the liquid sap as it poured out. As they were unable to keep the liquid for any length of time – they didn’t have storage facilities in those days – they boiled the liquid by placing pieces of rock that had become scorching hot from the sun into the sap. They did this until it turned into sugar, and they were then able to use this to sweeten their food and drinks. Since that time, improvements have been made to the process, but it has changed very little overall. So let’s look at the production of maple syrup today. Clearly, the maple forests are a valuable resource in many Canadian and North American communities. The trees have to be well looked after and they cannot be used to make syrup until the trunks reach a diameter of around 25 centimetres. This can take anything up to 40 years. As I’ve already mentioned, maple trees need the right conditions to grow and also to produce sap. Why is this? Well, what happens is that during a cold night, the tree absorbs water from the soil, and that rises through the tree’s vascular system. But then in the warmer daytime, the change in temperature causes the water to be pushed back down to the bottom of the tree. This continual movement – up and down – leads to the formation of the sap needed for maple syrup production. When the tree is ready, it can be tapped and this involves drilling a small hole into the trunk and inserting a tube into it that ends in a bucket. The trees can often take several taps, though the workers take care not to cause any damage to the healthy growth of the tree itself. The sap that comes out of the trees consists of 98 percent water and 2 percent sugar and other nutrients. It has to be boiled so that much of that water evaporates, and this process has to take place immediately, using what are called evaporators. These are basically extremely large pans – the sap is poured into these, a fire is built and the pans are then heated until the sap boils. As it does this, the water evaporates, and the syrup begins to form. The evaporation process creates large quantities of steam, and the sap becomes thicker and denser, and, at just the right moment, when the sap is thick enough to be called maple syrup, the worker removes it from the heat. After this process, something called ‘sugar sand’ has to be filtered out as this builds up during the boiling and gives the syrup a cloudy appearance and a slightly gritty taste. Once this has been done, the syrup is ready to be packaged so that it can be used for a whole variety of products. It takes 40 litres of sap to produce one litre of maple syrup so you can get an idea of how much is needed! So that’s the basic process. In places like Quebec where …
