Explanations
- 1. 1.15
- The witness works out the time: she left at one, the walk takes about ten minutes, but she stopped at a shop, 'so it was probably closer to one fifteen'.Common trap: Self-correction trap – she offers 'ten past one' first and then revises it to one fifteen in the same turn.
- 2. three
- 'There were three of them. Two in the front, the driver, of course, someone in the passenger seat, and there was someone in the back.'Common trap: Number-cluster trap – 'two in the front' and 'twenty' are both said around the answer, and 20 is already printed.
- 3. bicycle
- 'They came speeding out of the side road over there and hit that lady's bicycle.'Common trap: Possessive trap – the passage says 'that lady's bicycle' while the note says 'a woman on her ___'.
- 4. town centre
- 'He just drove off along the main road towards the town centre.'Common trap: Near-identical trap – 'main road' comes first in the sentence and is easy to write in instead of the destination.
- 5. traffic lights
- 'I know the traffic lights aren't working there, so perhaps they thought they could just pull out.'Common trap: Paraphrase trap – 'aren't working' in the talk becomes 'out of order' in the notes.
- 6. damaged
- 'It was red, like I said, and quite old, and the door on the driver's side was damaged.'Common trap: Detail-cluster trap – colour, age and damage are listed together, and the printed sentence already gives the colour and model.
- 7. BYW
- 'Y ... 4 ... 8 ... B ... Y ... W' – Y48 is already printed, so the answer is the last three letters.Common trap: Letter-dictation trap – the letters are read out one at a time with pauses, and Y appears twice.
- 8. Stansfield
- 'Mrs Stansfield. Rita Stansfield. That's S-T-A-N-S-F-I-E-L-D.'Common trap: Spelling trap – the surname is spelt out, and the first name is already printed.
- 9. Althorpe Road
- '19 Althorpe Road, Bradford. That's A-L-T-H-O-R-P-E.' The house number is printed and the city is not part of the street.Common trap: Word-limit trap – the town follows the street name immediately in the same breath.
- 10. 889772
- Asked for a mobile number as well, she gives '07834 889772'. The 07834 prefix is already printed.Common trap: Two-number trap – the landline is given first and is already printed on the line above.
- 11. are expensive.
- 'Having solar panels installed on the roof isn't a cheap enough option for many of us to consider seriously' – the cost is the barrier.Common trap: Same-sentence trap – popularity and 'consider seriously' both appear, one contradicted and one used differently.
- 12. do not use the kitchen efficiently.
- 'Most people will make a point of turning the heating down ... but they ignore other equally useful ways of saving energy when they're making dinner or doing their weekly laundry.'Common trap: Reversal trap – the heating is exactly what people already remember to do, and the laundry is mentioned but not criticised for frequency.
- 13. older
- 'For those of us in older properties, the chances are there are gaps all over the place where cold air is getting in.'Common trap: Contrast trap – 'a relatively new apartment' is described first, as the case where draughts are NOT a problem.
- 14. standby
- 'Then there's the laptop or your TV. Do you leave them switched on overnight or on standby? Don't waste money, turn them off.'Common trap: Question-form trap – the advice is delivered as a rhetorical question, so the key word has to be lifted out of it.
- 15. more water
- 'Why boil more water than you actually need?' – said of overfilling the kettle when making tea.Common trap: Paraphrase trap – 'making hot drinks' in the notes stands for 'makes a cup of tea' in the talk.
- 16. a lid
- 'The next time you're cooking pasta or potatoes, keep a lid on the pot. The water will boil much more quickly.'Common trap: Adjacent-tip trap – the pressure cooker and steamer are recommended in the very next sentence.
- 17. cooker
- 'If the fridge is next to the cooker, it's having to work harder to stay cold.'Common trap: Conditional trap – the point is made as an 'if' clause rather than as direct advice.
- 18. winter
- 'We often forget to turn it down in the colder winter months when a high setting is unnecessary.'Common trap: Negation trap – the talk says what people forget to do; the note turns it into a reminder.
- 19. defrost
- 'Remember to defrost the freezer frequently and try not to overfill it as this isn't the most efficient way of using it.'Common trap: Near-identical trap – the sentence mirrors the talk closely, so the verb must be picked out precisely.
- 20. 30
- 'A lot of people wash at 40°C but it's often OK to drop the temperature down to 30°C with similar results.'Common trap: Two-number trap – 40°C is said first and is what people currently do, not the recommendation.
- 21. She looked around the campus.
- 'I spent some time walking around the place first, just to get a feel for what it's like. I'm doing the organised events this afternoon. I thought I'd have a coffee before I get started.'Common trap: Sequence trap – all three actions are named in one turn; only the order tells you which came first.
- 22. a supermarket
- 'There's supposed to be a big supermarket a few minutes' walk from the main entrance' – outside the campus. The banks and bookshop are on it.Common trap: NOT-question trap – all three are mentioned positively, and the closing 'everything you need here' masks the one that is off campus.
- 23. The university will know you attended.
- 'They might check after to see if people have bothered to come to the Open Day, so I think it's best to register.'Common trap: Reason-versus-fact trap – the information pack and the unchecked events are both mentioned, as reasons registration is NOT required.
- 24. the number of mature students
- 'Being a bit older, I'm particularly keen on somewhere that has a few students my age on the course.' The facilities and business links are the same everywhere, so they do not decide it.Common trap: Levelling trap – facilities and industry links are praised, but precisely because they are equal at every university.
- 25. software development
- 'My Maths teacher at college was telling me about the opportunities in the software industry, which I quite like the sound of.'Common trap: Rejected-option trap – finance is named at length and then dismissed, and a teacher appears as the messenger.
- 26. C
- 'There's also someone who'll be explaining about the year abroad ... I'm going to have to give that a miss, though, to catch my train.'Common trap: Enthusiasm trap – she describes the year abroad in appealing detail before saying she has to miss it.
- 27. B
- 'There's also an exhibition area in the Physics Department with some of the things people are doing here. I'll try and catch that' – 'try' makes it uncertain.Common trap: Modality trap – 'I'll try and catch that' has to be graded as 'might' rather than 'will'.
- 28. A
- 'There's a talk later this afternoon by the head. I can't miss that' – a definite yes.Common trap: Speaker-swap trap – Oliver has already been to his own head of department's presentation, which is a different event.
- 29. accountancy firms
- 'A couple of accountancy firms in the area that offer work experience. That's on a voluntary basis, though.' The Open Day students get paid and the campus shops are hiring.Common trap: Contrast trap – the paid options are described immediately afterwards, marked by 'But apparently'.
- 30. does not yet know where he will live if he gets a place at the university.
- 'I've not made my mind up yet ... it would be a lot cheaper if I stayed at home. But it would be nice to get some independence as well, so I don't know. I'll have to see.'Common trap: Weighing-up trap – he sets out the case for both options in turn, so either one can sound like his decision.
- 31. confused
- 'Before then they were probably confused with the Antarctic or true blue whale.'Common trap: Reference trap – 'Before then' refers back to 1966 in the previous sentence, which is what the note prints.
- 32. population
- 'Very little is known about their movements and their populations.'Common trap: Order trap – the talk says 'movements and their populations'; the note reverses the pair, so the printed word must be skipped.
- 33. location
- 'The location of the whale can be determined when multiple satellites receive the tag's transmissions.'Common trap: Paraphrase trap – 'determined' becomes 'identified' and 'multiple satellites' becomes 'a number of satellites'.
- 34. website
- 'Researchers receive this location data in almost real time via the project website.'Common trap: Near-identical trap – 'the project ___' is printed, so only the final noun is missing.
- 35. west coast
- 'Pygmy blue whales do indeed travel northwards from the west coast of Australia in March and April.'Common trap: Direction trap – southern and western Australia are both named earlier as feeding grounds, and only one is the departure coast.
- 36. September
- 'They remain there until September, at which time they then return to Australian waters.'Common trap: Month-cluster trap – March, April and June are all given for the outward journey before the return month.
- 37. food
- 'The pygmy blue whales studied travel from productive feeding grounds off western Australia to productive areas in Indonesia and therefore probably still have the opportunity to feed whilst they're in their breeding grounds.'Common trap: Assumption-versus-finding trap – the general assumption is stated first and the finding contradicts it.
- 38. shipping
- 'The migratory routes of pygmy blue whales correspond closely with shipping routes ... there is potential for the noise generated by ships to affect communication.'Common trap: Two-routes trap – 'migratory routes' appears in the same sentence and is easy to write into the gap.
- 39. wider
- 'Now that this hypothesis has been borne out by evidence, conservation efforts can be undertaken in a wider area than just Australian waters.'Common trap: Near-identical trap – the note rewords 'borne out by evidence' as 'now there is evidence', so the gap must be located exactly.
- 40. subtropical
- 'Researchers are keen to discover whether the pygmy whales from the southern feeding grounds follow a similar migration route to those from the west coast or whether they migrate to the subtropical region to the south of Australia.'Common trap: Long-sentence trap – the answer is the last content word of a long two-branch sentence.

Part 1 — Reporting a road accident
Police officer: Hello madam. I understand you witnessed the accident. Have you got a few minutes to tell me what you saw? Woman: Yes, no problem. I don't have to be back at work for a while, so I'm pleased to help. Police officer: Did you actually see what happened? Woman: Yes. I was standing over there, near the bus stop. I was on my way to get something for lunch and just happened to be looking at a shop across the road. That's when I saw the red car come out from the junction over there. Police officer: You don't happen to know what time it occurred, do you? Woman: Well, I left work for my lunch break at one and it's only about ten minutes' walk away - the office, I mean - so it might have been about ten past one. Although I did pop into the shop for something, so it was probably closer to one fifteen. Police officer: So it pulled out of Monks Road - that's the road over there - straight onto High Street? Woman: That's right, yes. Police officer: Did you get a view of who was in the car? Woman: There were three of them. Two in the front, the driver, of course, someone in the passenger seat, and there was someone in the back. They were quite young. I doubt if they were much older than twenty. Anyway, they came speeding out of the side road over there and hit that lady's bicycle. The driver didn't bother to stop to find out if she was OK. He just drove off along the main road towards the town centre. Er, is the woman OK? Police officer: She should be fine. She banged her head when she came off the bike, so we've called for an ambulance - they always like to check you out in case you have concussion. But no, she seems fine. Woman: The bike doesn't look too good, though. I don't think she'll be using that again. I suppose she was very lucky, really. If they'd hit her instead of the front wheel, she could have been seriously injured. It looked like they were just in a hurry and didn't want to stop at the junction. I know the traffic lights aren't working there, so perhaps they thought they could just pull out. Police officer: Could you give me a description of the car? Do you know the make and model? Woman: Well, I'm not very good with cars, but I'm pretty sure it was the same model as my husband's car, a Ford Fiesta. It was red, like I said, and quite old, and the door on the driver's side was damaged. It looked like it had been in another accident some time ago. Police officer: I don't suppose you had a chance to take down the registration number, did you? Woman: I did, actually. Let me see ... Um, Y ... 4 ... 8 ... B ... Y ... W. Will that help you trace them? Police officer: That's really helpful. It depends. It might be a stolen car, but at least we'll be able to trace the owner. If it wasn't stolen, then yes, we'll be able to find out the name of the driver. Now, would you mind giving me your contact details, just in case we need to get in touch about anything? Woman: Of course. Police officer: What's your name? Woman: Mrs Stansfield. Rita Stansfield. That's S- T- A- N- S- F- I- E- L- D. Police officer: And your address, Mrs Stansfield? Woman: 19 Althorpe Road, Bradford. That's A- L- T- H- O- R- P- E. Police officer: Have you got a telephone number we can get you on? Woman: Yes, it's 0232 566788. Police officer: And do you have a mobile number? Woman: Yes ... 07834 889772. Police officer: That's great, Mrs Stansfield. As I said, we may get in touch if we need any further information, but probably what you've told me is enough. Thanks for your time. Woman: No problem. I'm glad to have been of help. Police officer: And do you have a mobile number? Woman: Yes ... 07834 889772. Police officer: That's great, Mrs Stansfield. As I said, we may get in touch if we need any further information, but probably what you've told me is enough. Thanks for your time. Woman: No problem. I'm glad to have been of help.
Part 2 — Saving energy at home
Speaker: Many thanks for inviting me along to talk about saving energy in the home. This is a key issue for many people who now find themselves on tight budgets. So today I'd like to spend a few minutes going through some simple tips to help keep those energy bills to a minimum. I'll start with some easy, cheap ideas before talking about more major solutions later. I think we're all aware of the importance of insulating our homes, and although I'd advise you to get it done, I appreciate it can sometimes be inconvenient to have building work carried out. And though they're growing in popularity, having solar panels installed on the roof isn't a cheap enough option for many of us to consider seriously. So what other steps can we take? Well, most people will make a point of turning the heating down when temperatures outside rise but they ignore other equally useful ways of saving energy when they're making dinner or doing their weekly laundry. If you're living in a relatively new apartment or house, you're probably blessed with a cosy, draught-free living space. But for those of us in older properties, the chances are there are gaps all over the place where cold air is getting in. Walk around your home and place the back of your hand around window frames. Can you feel cold air coming in from outside? Get down on your knees at the doors. Is there a draught at floor level? Fix these draughts with some cheap draught excluders and savings in heating bills will begin straight away. And are you using the latest energy-saving light bulbs? I'm not recommending you go around your entire property throwing out older ones and replacing them all immediately. But next time a bulb goes, make sure you buy an energy-efficient alternative. And what about heating? If you have radiators in every room, do you need them all switched on throughout the day? If they're on timers, set them efficiently. Then there's the laptop or your TV. Do you leave them switched on overnight or on standby? Don't waste money, turn them off. And that goes for lights as well. You'd be surprised how many people leave them on when they go out. There are also guaranteed savings to be made in the kitchen. I'm always telling my husband not to overfill the kettle when he makes a cup of tea. Why boil more water than you actually need? When you consider how many times that kettle gets used every day, you'll appreciate just how much electricity can be saved by boiling what you need and no more. And the next time you're cooking pasta or potatoes, keep a lid on the pot. The water will boil much more quickly than if you leave it off. And if you've bought yourself a pressure cooker or steamer and it's sitting in the cupboard never being used, get it out - they're much more efficient than pots and pans. Now, the refrigerator and freezer. If the fridge is next to the cooker, it's having to work harder to stay cold. But as I'm giving cheap, easy solutions here, a kitchen redesign might be out of the question. Still, there are other energy-saving steps you can take. Keep an eye on the temperature control. We often forget to turn it down in the colder winter months when a high setting is unnecessary. Also, remember to defrost the freezer frequently and try not to overfill it as this isn't the most efficient way of using it. The washing machine is another potential money saver. A lot of people wash at 40°C but it's often OK to drop the temperature down to 30°C with similar results. And remember to either wash full loads or select the half-load programme; again, a surprising number of people forget to do this. And is it really necessary to dry your clothes in a tumble drier? If you have a garden or a yard, hang them outside. Or if you're drying them inside, get yourself a cheap clothes rail rather than hanging things over radiators, which robs you of valuable heat. Now let's turn to some of the help our local council is offering to householders to save energy ...
Part 3 — At a university Open Day
Oliver: Excuse me, is this seat taken? Alice: No, by all means, have a seat. Are you here for the Open Day? Oliver: Yes, I think I've just about finished now. I got here first thing this morning. What about you? Alice: I got here a little while ago. I spent some time walking around the place first, just to get a feel for what it's like. I'm doing the organised events this afternoon. I thought I'd have a coffee before I get started. It's a lovely campus, isn't it? Oliver: Yes, I love it. And the facilities are unbelievable. I've just been over to have a look at the sports centre. There's an Olympic size swimming pool, a gym, squash courts, everything really. All the high street banks are here, and the bookshop looks better than the one in town. There's supposed to be a big supermarket a few minutes' walk from the main entrance, so there's pretty much everything you need here. Alice: Yes, I really like the look of it ... Um, I wonder if you can help me. I think I need to register to let them know I've arrived, don't I? Oliver: I'm not sure you have to. You can just pick up an information pack from the desk over there. And nobody asked my name or anything when I turned up for the events earlier. I just walked in. But you never know; they might check after to see if people have bothered to come to the Open Day, so I think it's best to register. Alice: Thanks. I'll just finish my coffee and then I'll get started. Oliver: So, is this your first Open Day? Alice: No, it's my fourth. I've been to Sussex, Coventry and Birmingham so far. They've all got their good points. But being a bit older, I'm particularly keen on somewhere that has a few students my age on the course. Apart from that, they all seem to have great links to businesses, and there isn't much to choose between them as far as their facilities are concerned. How about you? Oliver: I haven't been to any other Open Days yet but I'm hoping I end up here. I've just been to a presentation by the Head of Department. It sounds like a great place to do Maths - that's my subject. He was telling us about all the avenues open to Maths graduates and the kind of work you can end up doing. A lot of students go into finance, accountancy, banking, that kind of thing. I can't say that's ever appealed to me, though. My Maths teacher at college was telling me about the opportunities in the software industry, which I quite like the sound of. Alice: Well, I hope you manage to get in. According to the letter they sent me, my department is doing something similar. There's a talk later this afternoon by the head. I can't miss that. There's also someone who'll be explaining about the year abroad. Apparently, you can spend your third year at one of their partner universities in Spain or Germany. I'm going to have to give that a miss, though, to catch my train. Oh, and there's also an exhibition area in the Physics Department with some of the things people are doing here. I'll try and catch that. Oliver: There were a few second- and third-year students at the exhibition I went to. One of them gave me some great tips on finding work as well. I already knew about a couple of accountancy firms in the area that offer work experience. That's on a voluntary basis, though. But apparently the students helping here on the Open Day get paid, and the university advertises other jobs that come up now and again, so that's worth remembering. And a lot of the shops here are always looking for staff. Alice: Mm, that's useful to know. I overheard someone saying there's a tour of some of the halls of residence in about half an hour, so I think I'll register and try to fit that in before I go to the talk. Are you thinking of living on campus? Oliver: I've not made my mind up yet. I don't live far from here. My parents' place is just the other side of town. I could easily get the bus to campus, plus it would be a lot cheaper if I stayed at home. But it would be nice to get some independence as well, so I don't know. I'll have to see. But I didn't know about the tour. Would you mind if I tag along with you? Alice: No, not at all. Let me just finish my coffee and I'll go and register.
Part 4 — Tracking pygmy blue whales
Lecturer: Today we're going to continue our investigation into the use of technology in plotting oceanographic migratory patterns and I'd like to focus specifically on creatures that we didn't even realise existed until very recently: pygmy blue whales. In particular, I'd like to talk about a high-tech method of tracking that researchers have used to find out more about these creatures. Pygmy blue whales, which are one of several sub-species of blue whales, spend their lives in the vast expanses of the Indian and southern Pacific Oceans. They were first identified as a distinct subspecies in 1966. Before then they were probably confused with the Antarctic or 'true' blue whale, so it's only recently that researchers have started to learn about them and their migrations to and from their breeding and feeding grounds. Scientists are interested in pygmy blue whales because although they are a very mobile subspecies, very little is known about their movements and their populations. Large-scale movements of whales are particularly hard to study, and what we do know about pygmy blue whales we've mainly learnt from examining whaling records. There are several populations of pygmy blue whales in the southern hemisphere and two main feeding grounds off southern and western Australia. Scientists were interested in testing their hypothesis that the pygmy blue whales feeding off western Australia migrate to Indonesia to breed. To track the whales' movements, researchers made use of something called satellite telemetry. This refers to the use of a satellite-linked tag attached to a whale. When the antenna on the whale breaks the surface of the water, the tag communicates with a satellite system. The location of the whale can be determined when multiple satellites receive the tag's transmissions, much like how the navigation system works on a mobile phone. Researchers receive this location data in almost real time via the project website, which allows them to track the movement of the tagged whale from many miles away. The use of these tags has enabled researchers to discover that pygmy blue whales do indeed travel northwards from the west coast of Australia in March and April, reaching the warmer breeding grounds of Indonesia in June. They remain there until September, at which time they then return to Australian waters. In addition to identifying the migratory pattern of this particular population of pygmy whales, research has also shone new light on the whales' feeding patterns. It's usually assumed that whales go without food outside of the summer, when they leave their feeding grounds. But interestingly, the pygmy blue whales studied travel from productive feeding grounds off western Australia to productive areas in Indonesia and therefore probably still have the opportunity to feed whilst they're in their breeding grounds. It is hoped that mapping the migratory movements of the pygmy whales will help conservation efforts for these endangered animals, and the study has enabled researchers to identify specific conservation issues. For example, the migratory routes of pygmy blue whales correspond closely with shipping routes. Consequently, researchers are keen to monitor whether this has any negative effects on the whales' behaviour. Baleen whales - these are whales that use filters to feed, not teeth - use sounds to communicate and to gain information about their environment. Clearly, as pygmy blue whale movements correspond to shipping routes, there is potential for the noise generated by ships to affect communication and hence social encounters and feeding. Previously, researchers could only hypothesise that pygmy blue whales occupying western Australian waters travelled into Indonesian waters. Now that this hypothesis has been borne out by evidence, conservation efforts can be undertaken in a wider area than just Australian waters. However, scientists aren't stopping here. A question mark still remains over the movements of the pygmy blue whales that utilise the feeding grounds further south, off the southern coast of Australia. Genetic evidence indicates that there is a mixing taking place between the population of whales in the feeding grounds of western Australia and the population further south. Researchers are keen to discover whether the pygmy whales from the southern feeding grounds follow a similar migration route to those from the west coast or whether they migrate to the subtropical region to the south of Australia. As a result, there are plans to tag the pygmy blue whales further south in order to find out whether they move through the same areas as the western population and are therefore exposed to the same risks.
