You will hear two students discussing an assignment.
你將聽(tīng)到兩名學(xué)生正在討論一項(xiàng)作業(yè)。
First, you have some time to look at questions 21 to 25.
首先，你有些時(shí)間看看第二十一題至第二十五題。
Hi, Melanie, what did you think of the assignment that we got today? It looks interesting, doesn't it?
你好，梅勒妮，你覺(jué)得今天給我們布置的那份作業(yè)怎么樣？挺有趣的，不是嗎？
Yes, Alan, I've always been interested in recycling but there's a lot of research to do...
沒(méi)錯(cuò)，艾倫，我一直對(duì)回收資源很有興趣，但這得做大量調(diào)研……
Yes, there are a lot of things I'm unsure of, so it's going to be good working with you.
對(duì)，很多東西我都不確定，所以能與你合作可真是件好事。
OK. Well, why don't we start by making a flow chart from the notes our tutor gave us?
好。我們?yōu)楹尾幌乳_(kāi)始做個(gè)流程圖呢？可根據(jù)導(dǎo)師給我們的筆記來(lái)做。
Yes, um, so... On one side we could have the paper production cycle - here on the left - and on the other side the recycling.
好，在這一邊我們可以做紙張生產(chǎn)流程，就在左邊，另一邊做回收利用流程。
Good idea. Let's start at the top with the production. The first step in the process is to get the raw materials.
好主意。從頂上開(kāi)始做生產(chǎn)流程吧。第一步是獲取原材料。
Yes, and they tend to come from pine forests.
好，一般原材料都來(lái)自松樹(shù)林。
OK. And then the bark is removed from the outside of the tree and after that the wood is chopped up.
好。接著會(huì)將樹(shù)木外層樹(shù)皮除掉，然后把木頭切碎。
That's the first three stages.
這是最開(kāi)始的三個(gè)步驟。
It sounds a bit complicated after that. Um, it says water is added and then the mixture is heated and made into pulp.
之后的步驟看起來(lái)有點(diǎn)復(fù)雜。這里說(shuō)，要加水，
This will be the thick paste that is used to make paper.
然后加熱混合物制成紙漿。
Yes, you're right, because after that they use a machine to make the paper and we can put that right in the centre of the flow-chart because it's also where the recycled paper joins the process.
你說(shuō)得沒(méi)錯(cuò)，因?yàn)樵谶@之后會(huì)用機(jī)器造出紙張，我們可以把這個(gè)步驟放在流程圖中間，因?yàn)橐舱窃谶@一步再生紙加入整個(gè)流程。
Yes. So once the paper has been produced in the machine, what happens then?
對(duì)。一旦在機(jī)器中生成了紙張，接下來(lái)會(huì)發(fā)生什么呢？
Well, I think we should write "print" as the next step because this is when newspapers, magazines, etc. are produced.
我認(rèn)為我們下一步應(yīng)該寫(xiě)“印刷”，因?yàn)檫@一步是生產(chǎn)報(bào)紙和雜志等等的印刷品的。
And we could also add that they have to be distributed to stores and people's homes.
我們還能補(bǔ)充一下，紙張得配送到商店和百姓家庭中。
Right, then the recycling bit starts. The old paper's collected and then it says it's taken somewhere so that someone or something can sort it.
對(duì)，然后回收利用過(guò)程開(kāi)始了。先收集廢舊紙張，接著這里說(shuō)要把收集到的紙張送到某個(gè)地方，讓某些人或機(jī)器進(jìn)行篩選。
I imagine there are different kinds of paper or things like paper clips that need to be removed.
我想，有很多不同的東西是要被篩選除掉的，像回形針之類(lèi)。
Yes. Let's have a step after that. Now, how did our tutor say they do this? Oh, yes, it involves chemicals. So, how is your chemistry?
對(duì)。我們?cè)诤竺嫜a(bǔ)上這一步吧。導(dǎo)師關(guān)于這一步的做法說(shuō)了什么？噢，對(duì)，這涉及到化學(xué)知識(shí)。你的化學(xué)學(xué)得怎么樣？
Well, not very good I'm afraid. But this is how they remove ink, so... This is definitely going to need a bit of research.
恐怕不是很好。這里說(shuō)的是工作人員怎么去除墨水……這得做一些資料搜查。
Right. The last step in the recycling section is similar to the last step in the production process with heating and pulping before the cycle begins again.
沒(méi)錯(cuò)。回收利用的最后一步和生產(chǎn)的最后一步類(lèi)似，都是要加熱制成紙漿，接著又開(kāi)始新的一個(gè)循環(huán)。
