剑桥雅思4 test 4 Section 3听力原文与答案
这篇Section 3的整体难度要小于现在考试的正常难度。原因有二：其一，前半部分全都是表格填空题，而不是现在更为常见的选择。通常来说，填空的难度要远小于选择。其二，后半部分的匹配以同近义词的替换为主，而没有出现当下Section 3更为常见的词义解释、句子替换，造成难度小了许多。
剑4 test 4 Section 3雅思听力原文
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! Q21
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.
MIKK: 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, um, 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. Q22
SUE: Hmm, yes, that’s not bad.
MIKE: OK, now for number three you need rock salt or copper sulphate. Q23
SUE: Oh, I’m not sure about that!
MIKE: Well, just put down the rock salt then, um, apart from that you only need ajar of water. Um, and basically you dissolve lots of salt into the water and watch the crystals form, so it basically teaches the kids about growing crystals. Q24
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 color wheel’. It looks like you get some cardboard and draw a circle on it, divide it into six equal segments and color each one in using different colors, then you thread a piece of string through the middle. Q25
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 colors 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. Q26
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! Q27
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? Q28
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. Q29
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 coloring it in?
MIKE: OK, well, what about number five?
SUE: I thought this one sounded a bit too good to be true – great equipment!
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. Q30
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!
