Experiments for Children剑桥雅思4听力-原文翻译及答案解析

一、Experiments for Children 听力原文：

MIKE:Hi SUE

SUE:Hi MIKE, so what happened to you last week?

MIKE:Oh, I was sick with the flu.

What's this I hear about a big assignment we've got to do?

SUE:Well, basically, we've got to find two science experiments to do with a group of eight-year-old children at the local primary school, and we've got to complete it by the end of the week.

MIKE:Oh, that sounds like hard work.

Where are we supposed to get the ideas for these experiments from?

SUE:Well.I managed to get hold of two books from the library.

MIKE:Oh, well done!

SUE:How about if we take a look at the experiments in this book first and see if anything looks suitable?

I can make notes as we go, about equipment and the purpose of the experiments.

MIKE:OK, let's see, um, the first experiment is called 'Make your own hovercraft', which sounds very ambitious!

Mind you, you only need twenty balloons and a table - you don't need any special engines or anything like that!

SUE:What do you do with it all?

MIKE:Er, you blow up the balloons and you balance the table on them, upside down of course, and the kids get to ride around on it.

You know, the other kids sort of push them around the room.

The main purpose is to show how hovercrafts work, and how things hover around on just a cushion of air.

SUE:OK, that doesn't sound too bad.

MIKE:OK, ready for number two?

SUE:Uh-huh.

MIKE:Now this one is called Unusual Measures of Lengths', and you basically use lots of paperclips.

The kids go around the class measuring things - you know, how long the desk is, and that sort of thing, urn, and then they all compare their answers.

Er, and, basically, because not all paperclips are the same lengths, they should come up with some strange answers.

It's supposed to demonstrate the importance of having fixed units of measurement.

SUE:Hmm, yes, that's not bad.

MIKE:OK, now for number three you need rock salt or copper sulphate.

SUE:Oh, I'm not sure about that!

MIKE:Well, just put down the rock salt then, urn, apart from that you only need ajar of water.

Urn, and basically you dissolve lots of salt into the water and watch the crystals form, so it basically teaches the kids about growing crystals.

SUE:I suppose it would be nice to grow something.

Hmm.let's move on and have a look at number four.

MIKE:OK, this one is called ‘Spinning colour wheel’.

It looks like you get some cardboard and draw a circle on it, divide it into six equal segments and colour each one in using different colours, then you thread a piece of string through the middle.

SUE:So we’d need some string as well.

MIKE:Yes, sorry ... um ... and you spin the wheel around and if you can get it spinning fast enough, hopefully the colours all merge and show up as white.

SUE:Oh.I didn't know that.

What's the principle behind it?

MIKE:Well it's pretty elementary physics, really.

It teaches them about how white light or ordinary light is made up.

SUE:Hmm, well that doesn't sound too bad.

Now there's only one more left in this book isn't there?

What does that one say?

MIKE:Um, well it’s another one where they'd get to make something.

SUE:Sounds very interesting.

MIKE:You need quite a lot of equipment actually - a hand drill, an old record, a pin or needle, some paper and a bolt.

SUE:Hmm, go on, what do they have to do?

MIKE:Well, they basically make a record player.

The main idea is to teach them about recording sound, but hopefully they'd also see that you need motion and an amplifier to make the sound heard.

SUE:OK, well it does sound interesting.

Shall we go through all of those again and decide if any of them are going to be suitable?

MIKE:Right, number one.

I thought this one sounded nice: there'd be lots of activity and it doesn't need too much in the way of equipment.

SUE:Yes, that's true, but don't you think it's a bit risky to get a group of eight-year-olds pushing each other around a classroom like that?

Someone could get hurt.

No, I don't like the sound of that one at all!

MIKE:Maybe you're right

SUE:What about number two, with the paperclips?

It sounds tame enough.

MIKE:Yes, a bit too tame if you ask me.

I think it needs to be something a bit more active and interesting than that, don't you?

SUE:Yes, I suppose you're right.

We won't get a very good mark if the children don't actually enjoy the experiments, and I suppose we could turn them off science for good!

Well, what about the next one, number three?

MIKE:Now, I quite like the idea of this one.

SUE:Yes, so do I, but I seem to remember when we did it at high school we had to wait up to a fortnight before we saw any halfway decent results.

MIKE:Oh, yes well, that won’t be any good then.

We'll only see the kids for one or two hours at the most.

SUE:Yes, and we have to do the experiments and write up our results within a week, so that one won't do at all.

MIKE:OK, well, what did you think of number four?

SUE:I like the idea of it, but do you think it will be a bit elementary for them?

MIKE:Well they are only eight you know!

SUE:I know, but you know what I mean.

Don't you think the activity itself is a bit babyish?

MIKE:Hmm.maybe you're right

SUE:They might have fun but, I mean, cutting out a circle and colouring it in?

MIKE:OK, well, what about number five?

SUE:I thought this one sounded a bit too good to be true - great equipment!

MIKE:Yeah

SUE:But don't you think it's a bit ambitious for this age group?

I mean, I don't want to start off something and then have to abandon it if they just can't cope with it.

I could see us ending up doing just about all of the work for them.

MIKE:I guess you're right.

Oh well, maybe we could store that idea away for later.

SUE:Yep, let's hope this second book has something better!

二、Experiments for Children 听力中文翻译：

迈克：嗨，苏

苏：嗨，迈克，你上周怎么了？

迈克：哦，我得了流感。

我听说我们要做一个大任务，这是什么？

苏：嗯，基本上，我们必须在当地小学找到两个针对一群八岁儿童的科学实验，我们必须在本周末之前完成。

迈克：噢，听起来工作很辛苦。

我们应该从哪里得到这些实验的想法？

苏：嗯。我设法从图书馆弄到了两本书。

迈克：哦，干得好！

苏：我们先看看这本书中的实验，看看有没有合适的？

我可以一边做笔记，关于设备和实验的目的。

迈克：好吧，让我们看看，嗯，第一个实验叫做“制造你自己的气垫船”，听起来很有野心！

请注意，你只需要二十个气球和一张桌子——你不需要任何特殊的引擎或类似的东西！

苏：你怎么处理这些？

迈克：呃，你把气球吹起来，然后把桌子放在上面，当然是倒过来的，孩子们就可以骑着气球到处跑了。

你知道，其他的孩子在房间里推着他们。

主要目的是展示气垫船是如何工作的，以及物体是如何在气垫上盘旋的。

苏：好吧，听起来还不错。

迈克：好的，准备好了吗？

苏：嗯哼。

迈克：这一个叫做“不寻常的长度测量”，你基本上用了很多回形针。

孩子们在课堂上四处测量东西——你知道，桌子有多长，等等，然后他们都比较自己的答案。

呃，而且，基本上，因为不是所有的回形针都是相同的长度，他们应该会想出一些奇怪的答案。

它应该证明拥有固定计量单位的重要性。

苏：嗯，是的，还不错。

迈克：好的，现在第三条你需要岩盐或硫酸铜。

苏：哦，我不确定！

迈克：嗯，那就把岩盐放下吧，瓮，除此之外，你只需要半开的水。

基本上，你在水中溶解大量的盐，观察晶体的形成，所以它基本上教会了孩子们如何生长晶体。

苏：我想种点东西会很好。

嗯，让我们继续看第四个。

迈克：好的，这个叫做“旋转色轮”。

它看起来像是你拿了一些纸板，在上面画了一个圈，把它分成六个等分的部分，用不同的颜色给每个部分涂上颜色，然后用一根绳子穿过中间。

苏：所以我们还需要一些绳子。

迈克：是的，对不起。。。嗯。。。你转动轮子，如果你能让它转得足够快，希望所有的颜色都融合在一起，显示为白色。

苏：哦。我不知道。

背后的原则是什么？

迈克：这是相当基础的物理，真的。

它告诉他们白光或普通光是如何构成的。

苏：嗯，听起来还不错。

现在这本书只剩下一本了，不是吗？

那个说什么？

迈克：嗯，这是另一个他们可以做点什么的地方。

苏：听起来很有趣。

迈克：实际上你需要很多设备——手钻、旧唱片、针、纸和插销。

苏：嗯，继续，他们要做什么？

迈克：嗯，他们基本上是做唱片机的。

主要的想法是教他们如何录音，但希望他们也能看到你需要运动和放大器来让声音被听到。

苏：好吧，听起来确实很有趣。

我们是否应该再检查一遍，然后决定其中是否有合适的？

迈克：对，第一。

我觉得这个听起来不错：会有很多活动，不需要太多的设备。

苏：没错，但你不觉得让一群八岁的孩子在教室里互相推搡有点冒险吗？

有人可能会受伤。

不，我一点也不喜欢那声音！

迈克：也许你是对的

苏：第二个呢，用回形针？

听起来很温和。

迈克：是的，如果你问我的话，有点太温顺了。

我认为它需要比那更活跃、更有趣的东西，不是吗？

苏：是的，我想你是对的。

如果孩子们真的不喜欢这些实验，我们就不会取得很好的成绩，我想我们可以永远让他们远离科学！

那么，下一个呢，第三个？

迈克：我很喜欢这个主意。

苏：是的，我也是。但我似乎还记得，当我们在高中做这件事的时候，我们要等上两个星期，才能看到半途而废的成绩。

迈克：哦，是的，那就不好了。

我们最多只能看孩子一到两个小时。

苏：是的，我们必须在一周内做实验并把结果写出来，这样就根本做不到了。

迈克：好吧，你觉得第四号怎么样？

苏：我喜欢这个主意，但你认为这对他们来说会有点初级吗？

迈克：你知道，他们只有八个人！

苏：我知道，但你知道我在说什么

你不觉得这个活动本身有点幼稚吗？

迈克：嗯，也许你是对的

苏：他们可能会很有趣，但我的意思是，划出一个圆圈并涂上颜色？

迈克：好的，那么，第五号呢？

苏：我觉得这个听起来有点太好了，不可能是真的-很棒的设备！

迈克：是的

苏：但你不觉得这对这个年龄段的人来说有点雄心勃勃吗？

我的意思是，我不想一开始就做一些事情，如果他们无法应付，我就不得不放弃。

我可以看到我们最终为他们做了几乎所有的工作。

迈克：我想你是对的。

哦，好吧，也许我们可以把这个想法留到以后再说。

苏：是的，希望这第二本书有更好的内容！

五、Experiments for Children 听力答案解析

Question 21  20 balloons. 考生通过听前预测得知答案为一种设备，录音中提到 you only need twenty balloons and a table，因为题目中已给出 table，所以此题的答案并不难捕捉。

Question 22  units of measurement/measurements/measurement units. 本题难度较大，题目中的信息在录 音中无原词重现，所以考生需要通过理解才能捕捉答案。当考生听到 It’s supposed to demonstrate the importance of having fixed units of measurement 时，应意识到题目中的 show 和 standard 与录音 当中的 demonstrate 和 fixed 为同义词替换，因此答案为 units of measurement。

Question 23 rock salt/salt. 当录音中出现卷面中的信号词 experiment 时，考生应意识到答案即将出现， 录音中接着提到 you need rock salt or copper sulphate，由此可知答案正是 rock salt/salt。

Question 24  crystals. 随后录音提到 it basically teaches the kids about growing crystals，growing 对应题目中的定位信号词 grow，故答案为 crystals。

Question 25  string / piece of string. 录音首先提到 divide it into six equal segments and colour each one in using different colours，then you thread a piece of string through the middle，其中 colour 被 反复提到， 正是卷面中的定位信号词，之后出现的“then”可以提醒考生答案为 piece of string。

Question 26  （ordinary）（white）light. 录音中提到 It teaches them about how white light or ordinary light is made up，考生可以通过卷面中的定位信号词 how 及 made up 确定正确答案为 light。

Question 27   H. 在录音中，男生说 Right，number one. I thought this one sounded nice: there’d be lots   of activity and doesn’t need too much in the way of equipment，随后，女生却说 Yes，that’s true，but    don’t you think it’s a bit risky to get a group of eight-year-olds pushing each other around a classroom like that? Someone could get hurt，男生也同意此观点，答道 Maybe you’re right，其中 risky 正是答案的信号 词，与  dangerous 相匹配，所以选 H。

Question 28 B. 对于第二个实验的评价是 I think it needs to be something a bit more active and interesting than that，这个实验应该更活泼有趣，故对应答为 B。

Question 29   E. 第三个实验耗时太长。录音提到 I seem to remember when we did it at high school we had to wait up to a fortnight before we saw any halfway decent results （我记得自己在高中做这个实验 时，为了得到一个不错的结果，我们要足足等上  14  天），因此答案为 E。

Question 30  c. 录音内容提到 But don’t you think it’s a bit ambitious for this age group? I mean，I don’t want to start off something and then have to abandon it if they just can’t cope with it，即对于这个年龄组 来说，这个试验太有难度，有可能半途而废，因此答案为  C。
