  劍橋雅思11test2聽力解析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?

  題目解析：本題通過aim進行定位，聽到 need something…之后，選項A符合，但是選項B可能會造成干擾，但是隨即被否定，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.

  題目解析：題目問的是忘記帶的東西是什么，ruler被提及，但是未表示是否攜帶，僅僅說明用途，compass說了已經(jīng)攜帶。Helen說到but not the piece of string且語氣突出。

  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.

  題目解析：通過procedure比較好定位，題目問的是Colin建議的一個改變，A不涉及，B被提及，但是屬于解釋details的內(nèi)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.

  題目解析：wave speed 幫助定位，straightforward的意思為“直接、明了”，選項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.

  題目解析：Helen說需要站在高處才能獲得better visibility，說明起初站的位置不對，B選項符合。Had to do it while the tide was low 否定了C選項，因為沒有說這個時間有錯或說需要更改。

  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.

  題目解析：Helen稱需要make amendments 且然后 scan it into our report，動作的主體都是對pictures的，A不符合原文意義，C選項涉及原文的internet，但是找出的是information，與原文提及的從網(wǎng)上下載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...

  題目解析：splash zone 原文重現(xiàn)，題干中的problem 和 原文的danger是同義替換。Helen說外殼可以避免它們變干，因為它們大部分時間都暴露在空氣中;D中high temperature與 too hot為同義替換。

  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.

  題目解析：error這個詞用于定位原文答題信息，應(yīng)該在原文中應(yīng)捕捉負(fù)面信息。We might have missed… I’m not sure… 均為重要提示。在仔細(xì)預(yù)讀題目選項之后，只有C和E符合選項。
