SUSIE: So Luke, for our next psychology assignment we have to do something on sleep and dreams.
LUKE: Right. I’ve just read an article suggesting why we tend to forget most of our dreams soon after we wake up. I mean, most of my dreams aren’t that interesting anyway, but what it said was that if we remembered everything, we might get mixed up about what actually happened and what we dreamed 【Q21】. So it’s a sort of protection. I hadn’t heard that idea before. I’d always assumed that it was just that we didn’t have room in our memories for all that stuff.
SUSIE: Me too. What do you think about the idea that our dreams may predict the future?
LUKE: It’s a belief that you get all over the world.
SUSIE: Yeah, lots of people have a story of it happening to them, but the explanation I’ve read is that for each dream that comes true, we have thousands that don’t 【Q22】, but we don’t notice those, we don’t even remember them. We just remember the ones where something in the real world, like a view or an action, happens to trigger a dream memory.
LUKE: Right. So it’s just a coincidence really. Something else I read about is what they call segmented sleeping. That’s a theory that hundreds of years ago, people used to get up in the middle of the night and have a chat or something to eat, then go back to bed. So I tried it myself.
SUSIE: Why?
LUKE: Well it’s meant to make you more creative. I don’t know why. But I gave it up after a week. It just didn’t fit in with my lifestyle.
SUSIE: But most pre-school children have a short sleep in the day don’t they? There was an experiment some students did here last term to see at what age kids should stop having naps. But they didn’t really find an answer 【Q23】. They spent a lot of time working out the most appropriate methodology, but the results didn’t seem to show any obvious patterns.
LUKE: Right. Anyway, let’s think about our assignment. Last time I had problems with the final stage, where we had to describe and justify how successful we thought we’d been 【Q24】. I struggled a bit with the action plan too.
SUSIE: I was OK with the planning, but I got marked down for the self-assessment as well. And I had big problems with the statistical stuff, that’s where I really lost marks.
LUKE: Right.
SUSIE: So shall we plan what we have to do for this assignment?
LUKE: OK.
SUSIE: First, we have to decide on our research question. So how about ‘Is there a relationship between hours of sleep and number of dreams?’
LUKE: OK. Then we need to think about who we’ll do they study on. About 12 people?
SUSIE: Right. And shall we use other psychology students?
LUKE: Let’s use people from a different department. What about history? 【Q25】
SUSIE: Yes, they might have interesting dreams! Or literature students?
LUKE: I don’t really know any.
SUSIE: OK, forget that idea. Then we have to think about our methodology. So we could use observation, but that doesn’t seem appropriate.
LUKE: No. it needs to be self-reporting I think. And we could ask them to answer questions online.
SUSIE: But in this case, paper might be better 【Q26】 as they’ll be doing it straight after they wake up … in fact while they’re still half-asleep.
LUKE: Right. And we’ll have to check the ethical guidelines 【Q27】 for this sort of research.
SUSIE: Mm, because our experiment involves humans, so there are special regulations.
LUKE: Yes, I had a look at those for another assignment I did. There’s a whole section on risk assessment, and another section on making sure they aren’t put under any unnecessary stress. 【Q28】
SUSIE: Let’s hope they don’t have any bad dreams!
LUKE: Yeah.
SUSIE: Then when we’ve collected all our data we have to analyse it and calculate the correlation between our two variables, that’s time sleeping and number of dreams and then present our results visually in a graph. 【Q29】
LUKE: Right. And the final thing is to think about our research and evaluate it 【Q30】. So that seems quite straightforward.
SUSIE: Yeah. So now let’s …
Choose the correct letter, A, B or C.
听前预测：定位词为 forget dreams；限定词为 Luke、reason。
题目解析：定位词在录音中被替换为 forget most of our dreams 后，答案句由 if 引出“… if we remembered everything, we might get mixed up about what actually happened and what we dreamed.”。这句话用 if 引导的条件句来解释忘记梦境的原因，对应 B 选项；紧接着会听到“So it’s …”，其中 So 表明上一句就是原因，可进一步确定答案为 B。注意不要进行过度推断，虽然 Luke 提及他做的梦并不好玩，但不能理解为“不重要”，故 C 不能选。最后听到 A 选项的相关信息，但是其表述为 “I’d always assumed”，意为“我原来一直以为”，这说明与实际情况恰恰相反，故 A 不能选。注意积累类似 I’d thought、I’d intended 等表达。
听前预测：定位词为 predicting the future；限定词为 agree。
题目解析：定位词原词出现，Susie 的解释中出现答案句“… for each dream that comes true, we have thousands that don’t.”（每当一个梦想成真，我们就有成千上万个梦想没有成真。）。这句话表明这只是概率问题，随后 Luke 表示赞同，总结道 “So it’s just a coincidence really.”，其中 coincidence 是 A 选项中 chance 的同义替换，因此答案为 A。
听前预测：定位词为 pre-school children、short nap；限定词为 Susie。
题目解析：定位词原词出现，但和上一题间隔稍远，注意根据内容来判断定位词位置。转折词 But 引出答案句“But they didn’t find an answer.”，可暂时判断 C 选项正确，然后听到 B 选项的 methodology，但没有提及 faulty 一词，说的是 the most appropriate，故 B 不能选。随后继续解释道“… the results didn’t seem to show any obvious patterns.”，其中 results 对应 C 选项中的 conclusions，obvious 对应 clear，可进一步确定答案为 C。注意不要过度推断，“没有真正找到答案”“没有显示任何明显的模式”不等于“充满争议的结论”，故 A 不能选。
听前预测：定位词为 last assignment；限定词为 both、problems。
题目解析：定位词 assignment 原词出现，紧接着 last time 原词出现并引出答案句“… I had problems with the final stage, where we had to describe and justify how successful we thought we’d been.”。随后听到 Luke 说他 action plan 方面也有问题（B 选项）， 但 Susie 随后说她这方面没问题，不符合题干 both 这一限定要求，故 B 不能选。Susie 随后说“I got marked down for the self-assessment as well.”，对应 C 选项，其中 as well 暗示 Luke 说的问题属于 self-assessment，符合题干 both 这一限定要求，因此答案为 C。注意本题其实 Luke 一开始就给出了 C 选项的替换信息 justify how successful we thought we’d been，但仅通过这一句来判断答案，难度相对较大。最后 Susie 提到 statistical stuff，符合 A 选项的表述，但 Luke 回答说“Right.”。注意理解该词的词义，Luke 只是表达其了解 Susie 所说的话，并没有说自己在这方面也有问题，故 A 不能选。
