  剑桥雅思11test2听力解析Section3

  Question21 A

  定位原文：scripts:

  COLIN: I just put something about getting experience of the different sorts of procedures used on a field trip. But we need something about what causes different organisms to choose particular habitats.

  HELEN: I agree. And something about finding out how to protect organisms in danger of dying out?

  题目解析：本题通过aim进行定位，听到 need something…之后，选项A符合，但是选项B可能会造成干扰，但是随即被否定，but we weren‘t really looking at that。

  Question22 A

  定位原文：scripts:

  COLIN: It was something about measuring the slope of the shore, but of course we didn't need it because we were measuring wind direction, and we'd brought the compass for that...

  HELEN: But not the piece of string to hold up in the air! Didn‘t Mr. Blake make a fuss about us leaving that behind.

  题目解析：题目问的是忘记带的东西是什么，ruler被提及，但是未表示是否携带，仅仅说明用途，compass说了已经携带。Helen说到but not the piece of string且语气突出。

  Question23 C

  定位原文：scripts:

  HELEN: Now, the next section's the procedure. I sent you the draft of that.

  COLIN: Yeah. It was clear, but I don't think we need all these details of what time we left and what time we got back and how we divided up the different research tasks.

  HELEN: OK. I'll look at that again.

  题目解析：通过procedure比较好定位，题目问的是Colin建议的一个改变，A不涉及，B被提及，但是属于解释details的内容。

  Question24 B

  定位原文：scripts:

  COLIN: Then we have to describe our method of investigation in detail. So let's begin with how we measured wave speed. I was surprised how straightforward that was.

  HELEN: I'd expected us to have some sort of high-tech device, not just stand there and count the number of waves per minute. Not very precise, but I suppose it was good enough. But the way we measured the amount of salt was interesting.

  题目解析：wave speed 帮助定位，straightforward的意思为“直接、明了”，选项B符合。

  Question25 B

  定位原文：scripts:

  HELEN：OK. And we need the map of the seashore. You just left that to me. And I had to do it while the tide was low, well that was OK, but the place I started it from was down on the beach, then I realized I should have gone up higher to get better visibility, so I had to start all over again. But at least I'd got the squared paper or I'd have had problems drawing it all to scale.

  COLIN: Yes. It looks good. We could get a map of the region off the internet and see if we need to make any changes.

  题目解析：Helen说需要站在高处才能获得better visibility，说明起初站的位置不对，B选项符合。Had to do it while the tide was low 否定了C选项，因为没有说这个时间有错或说需要更改。

  Question26 B

  定位原文：scripts:

  COLIN: Yes. It looks good. We could get a map of the region off the internet and see if we need to make any changes.

  HELEN: I had a look but I couldn't find anything. But you took some pictures, didn't you?

  COLIN: Yeah. I'll email you them if you want.

  HELEN: OK. I'll make my amendments using those, then I can scan it into our report.

  题目解析：Helen称需要make amendments 且然后 scan it into our report，动作的主体都是对pictures的，A不符合原文意义，C选项涉及原文的internet，但是找出的是information，与原文提及的从网上下载map不符。

  Question27&Question28 A D (in either order)

  定位原文：scripts:

  COLIN: ...the splash zone?

  HELEN: Yeah, we found mostly those tiny shellfish that have strong hard shells that act as protection.

  COLIN: But not from other organisms that might eat them, predators?

  HELEN: No, that's not the main danger for them.A: But the shells prevent them from drying out because they're in the open air for most of the time.

  COLIN: Right. And since they're exposed, they need to be able to find some sort of shelter, or cover themselves up, D:so they don't get too hot Then in the middle and lower zones, nearer the sea, we need to discuss the effects of

  E: wave action...

  题目解析：splash zone 原文重现，题干中的problem 和 原文的danger是同义替换。Helen说外壳可以避免它们变干，因为它们大部分时间都暴露在空气中;D中high temperature与 too hot为同义替换。

  Question29&Question30 C E (in either order)

  定位原文：scripts:

  HELEN: Right. OK, now I did a draft of the section of sources of possible error in our research, but I don't know if you agree. For example, D: the size of the sample, and whether it's big enough to make any general conclusions from. But I thought actually we did have quite a big sample.

  COLIN: We did. B: And our general method of observation seemed quite reliable. But we might not be all that accurate as far as the actual numbers go.

  Yeah, E: we might have missed some organisms - if they were hiding under a rock, for example. I wasn't sure about the way we described their habitats. I decided it was probably OK.

  COLIN: Yeah, and the descriptions we gave of the smaller organisms, they weren't very detailed, but they were adequate in this context. C: I'm not sure we identified all the species correctly though.

  题目解析：error这个词用于定位原文答题信息，应该在原文中应捕捉负面信息。We might have missed… I’m not sure… 均为重要提示。在仔细预读题目选项之后，只有C和E符合选项。
