聽力測驗技巧第二篇

問題1到7: 把空格的字填上

你必須要根據錄音帶中的訊息，把表格裡的空格填上。每個空格所填寫的字不可超過三個字，或是要填寫一個號碼。
好好地詳讀每個表格，而且要看一下範例答案，再進行對話。試著預測各種有可能的答案。這可幫助你在接下來的對話(錄音播放)中，辨認出關鍵的字。

問題7到10: 分類

這一類的題目，你必須要注意聽細節，以展現出你對錄音內容 - 不同事物 - 在關係上的了解。
The following statements are true about which of these products according to the dialogue?

聽力測驗第三部分: 對話 (可以的話，請兩個朋友或是多一點朋友來大聲念出)

Two friends are preparing a presentation on recycling for a university course they are studying. Listen as they discuss their findings.

Toby:So Chris, have you come up with any useful information?

Chris:Well, I've been looking at some material in the library, and I've found out quite a lot on the history of recycling.

Toby:History? That could be useful in our presentation. I'd only thought of it as being a recent phenomenon.

Chris:No, far from it. Apparently we humans have been recycling for most of our history. Archaeological studies show that as far back as in ancient Greece, people were recycling household waste, tools, pottery that kind of thing.

Toby:I suppose they had to make the best use of what they had around.

Chris:Yeah. Then, studies have found that in pre-industrial times, bronze was melted down and recycled repeatedly, and ash from fires was used to make bricks.

Toby:Right. It was all relatively simple back then though. When did modern recycling as we know it really begin?

Chris:It wasn't really until the Second World War that recycling took off on an industrial scale. A lot of countries urged citizens to donate metals and cloth as part of the patriotic war effort.

Toby:Of course, I remember learning about the collections of pots and pans when I was at school.

Chris:More recently, er… let me see. Ah, yes, there was big investment in recycling inthe 1970s due to rising energy costs. They found that recycling aluminium, for example, only used 5% of the energy required to produce it from scratch.

Toby:I guess that was to do with the oil crisis back then. Right, well while you've been doing that, I've been looking at some of the products we commonly recycle today, and making notes on some of the difficulties involved.

Chris:That sounds intriguing. What have you found out so far?

Toby:Well, it seems batteries are a high priority in a lot of countries.

Chris:Why's that?

Toby:The main reason is they contain heavy metals and toxic chemicals which can do a lot of damage to the environment. The problem is that there are such a large variety of shapes and sizes, and that makes sorting is very difficult. They also have to be handled with extreme care.

Chris:Right, batteries. Anything else?

Toby:Yep. I've also looked at the situation with glass. I've read that it makes up a large proportion of household waste these days, but fortunately it is relatively easy to recycle; according to one of the sites I looked at 752,000 tons of glass is now recycled annually in the United Kingdom. They say it's an ideal material for recycling because it's virtually infinitely recyclable, although to be really green it's better to re-use the original bottles rather than to use recycled glass to produce new ones.

Chris:What about plastic? We get through so much of it these days.

Toby:Yeah, I know. I'm just coming to that. Unfortunately, compared to other products, plastic is quite difficult to recycle. I mean, in Britain for example, we only recycle 24% of our plastic bottles, which isn't much when you consider that 80% of paper is re-used.

Chris:That's a massive difference! Why don't they recycle more of the stuff?

Toby:Well, according to a government information sheet I downloaded, compared to other materials, recycling plastic is very complex.

Chris:Don't they just melt it down?

Toby:Yes, but the problem is that there are so many different types of plastic, and they have to be separated before they are melted down. If different types are mixed together, they separate, a bit like oil and water, and they can't be re-used.

Chris:I guess we should all just try and use fewer bottles and plastic bags.

Toby:You're probably right. Anyway, going back to paper for a minute, I've discovered that in 1972, a staggering … (fade)
