Experiments for Children劍橋雅思4聽力-原文翻譯及答案解析

一、Experiments for Children 聽力原文：

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 聽力中文翻譯：

邁克：嗨，蘇

蘇：嗨，邁克，你上周怎么了？

邁克：哦，我得了流感。

我聽說我們要做一個大任務(wù)，這是什么？

蘇：嗯，基本上，我們必須在當(dāng)?shù)匦W(xué)找到兩個針對一群八歲兒童的科學(xué)實驗，我們必須在本周末之前完成。

邁克：噢，聽起來工作很辛苦。

我們應(yīng)該從哪里得到這些實驗的想法？

蘇：嗯。我設(shè)法從圖書館弄到了兩本書。

邁克：哦，干得好！

蘇：我們先看看這本書中的實驗，看看有沒有合適的？

我可以一邊做筆記，關(guān)于設(shè)備和實驗的目的。

邁克：好吧，讓我們看看，嗯，第一個實驗叫做“制造你自己的氣墊船”，聽起來很有野心！

請注意，你只需要二十個氣球和一張桌子——你不需要任何特殊的引擎或類似的東西！

蘇：你怎么處理這些？

邁克：呃，你把氣球吹起來，然后把桌子放在上面，當(dāng)然是倒過來的，孩子們就可以騎著氣球到處跑了。

你知道，其他的孩子在房間里推著他們。

主要目的是展示氣墊船是如何工作的，以及物體是如何在氣墊上盤旋的。

蘇：好吧，聽起來還不錯。

邁克：好的，準(zhǔn)備好了嗎？

蘇：嗯哼。

邁克：這一個叫做“不尋常的長度測量”，你基本上用了很多回形針。

孩子們在課堂上四處測量東西——你知道，桌子有多長，等等，然后他們都比較自己的答案。

呃，而且，基本上，因為不是所有的回形針都是相同的長度，他們應(yīng)該會想出一些奇怪的答案。

它應(yīng)該證明擁有固定計量單位的重要性。

蘇：嗯，是的，還不錯。

邁克：好的，現(xiàn)在第三條你需要巖鹽或硫酸銅。

蘇：哦，我不確定！

邁克：嗯，那就把巖鹽放下吧，甕，除此之外，你只需要半開的水。

基本上，你在水中溶解大量的鹽，觀察晶體的形成，所以它基本上教會了孩子們?nèi)绾紊L晶體。

蘇：我想種點東西會很好。

嗯，讓我們繼續(xù)看第四個。

邁克：好的，這個叫做“旋轉(zhuǎn)色輪”。

它看起來像是你拿了一些紙板，在上面畫了一個圈，把它分成六個等分的部分，用不同的顏色給每個部分涂上顏色，然后用一根繩子穿過中間。

蘇：所以我們還需要一些繩子。

邁克：是的，對不起。。。嗯。。。你轉(zhuǎn)動輪子，如果你能讓它轉(zhuǎn)得足夠快，希望所有的顏色都融合在一起，顯示為白色。

蘇：哦。我不知道。

背后的原則是什么？

邁克：這是相當(dāng)基礎(chǔ)的物理，真的。

它告訴他們白光或普通光是如何構(gòu)成的。

蘇：嗯，聽起來還不錯。

現(xiàn)在這本書只剩下一本了，不是嗎？

那個說什么？

邁克：嗯，這是另一個他們可以做點什么的地方。

蘇：聽起來很有趣。

邁克：實際上你需要很多設(shè)備——手鉆、舊唱片、針、紙和插銷。

蘇：嗯，繼續(xù)，他們要做什么？

邁克：嗯，他們基本上是做唱片機的。

主要的想法是教他們?nèi)绾武浺?，但希望他們也能看到你需要運動和放大器來讓聲音被聽到。

蘇：好吧，聽起來確實很有趣。

我們是否應(yīng)該再檢查一遍，然后決定其中是否有合適的？

邁克：對，第一。

我覺得這個聽起來不錯：會有很多活動，不需要太多的設(shè)備。

蘇：沒錯，但你不覺得讓一群八歲的孩子在教室里互相推搡有點冒險嗎？

有人可能會受傷。

不，我一點也不喜歡那聲音！

邁克：也許你是對的

蘇：第二個呢，用回形針？

聽起來很溫和。

邁克：是的，如果你問我的話，有點太溫順了。

我認為它需要比那更活躍、更有趣的東西，不是嗎？

蘇：是的，我想你是對的。

如果孩子們真的不喜歡這些實驗，我們就不會取得很好的成績，我想我們可以永遠讓他們遠離科學(xué)！

那么，下一個呢，第三個？

邁克：我很喜歡這個主意。

蘇：是的，我也是。但我似乎還記得，當(dāng)我們在高中做這件事的時候，我們要等上兩個星期，才能看到半途而廢的成績。

邁克：哦，是的，那就不好了。

我們最多只能看孩子一到兩個小時。

蘇：是的，我們必須在一周內(nèi)做實驗并把結(jié)果寫出來，這樣就根本做不到了。

邁克：好吧，你覺得第四號怎么樣？

蘇：我喜歡這個主意，但你認為這對他們來說會有點初級嗎？

邁克：你知道，他們只有八個人！

蘇：我知道，但你知道我在說什么

你不覺得這個活動本身有點幼稚嗎？

邁克：嗯，也許你是對的

蘇：他們可能會很有趣，但我的意思是，劃出一個圓圈并涂上顏色？

邁克：好的，那么，第五號呢？

蘇：我覺得這個聽起來有點太好了，不可能是真的-很棒的設(shè)備！

邁克：是的

蘇：但你不覺得這對這個年齡段的人來說有點雄心勃勃嗎？

我的意思是，我不想一開始就做一些事情，如果他們無法應(yīng)付，我就不得不放棄。

我可以看到我們最終為他們做了幾乎所有的工作。

邁克：我想你是對的。

哦，好吧，也許我們可以把這個想法留到以后再說。

蘇：是的，希望這第二本書有更好的內(nèi)容！

五、Experiments for Children 聽力答案解析

Question 21  20 balloons. 考生通過聽前預(yù)測得知答案為一種設(shè)備，錄音中提到 you only need twenty balloons and a table，因為題目中已給出 table，所以此題的答案并不難捕捉。

Question 22  units of measurement/measurements/measurement units. 本題難度較大，題目中的信息在錄 音中無原詞重現(xiàn)，所以考生需要通過理解才能捕捉答案。當(dāng)考生聽到 It’s supposed to demonstrate the importance of having fixed units of measurement 時，應(yīng)意識到題目中的 show 和 standard 與錄音 當(dāng)中的 demonstrate 和 fixed 為同義詞替換，因此答案為 units of measurement。

Question 23 rock salt/salt. 當(dāng)錄音中出現(xiàn)卷面中的信號詞 experiment 時，考生應(yīng)意識到答案即將出現(xiàn)， 錄音中接著提到 you need rock salt or copper sulphate，由此可知答案正是 rock salt/salt。

Question 24  crystals. 隨后錄音提到 it basically teaches the kids about growing crystals，growing 對應(yīng)題目中的定位信號詞 grow，故答案為 crystals。

Question 25  string / piece of string. 錄音首先提到 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 反復(fù)提到， 正是卷面中的定位信號詞，之后出現(xiàn)的“then”可以提醒考生答案為 piece of string。

Question 26  （ordinary）（white）light. 錄音中提到 It teaches them about how white light or ordinary light is made up，考生可以通過卷面中的定位信號詞 how 及 made up 確定正確答案為 light。

Question 27   H. 在錄音中，男生說 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，隨后，女生卻說 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，男生也同意此觀點，答道 Maybe you’re right，其中 risky 正是答案的信號 詞，與  dangerous 相匹配，所以選 H。

Question 28 B. 對于第二個實驗的評價是 I think it needs to be something a bit more active and interesting than that，這個實驗應(yīng)該更活潑有趣，故對應(yīng)答為 B。

Question 29   E. 第三個實驗耗時太長。錄音提到 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 （我記得自己在高中做這個實驗 時，為了得到一個不錯的結(jié)果，我們要足足等上  14  天），因此答案為 E。

Question 30  c. 錄音內(nèi)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，即對于這個年齡組 來說，這個試驗太有難度，有可能半途而廢，因此答案為  C。
