题目内容

We all think ________ helpful for our study to have a break at the weekends.

[　　]

A．it

B．that

C．this

D．/

答案：A
解析：

解析：本题谓语动词是think，空格后是形容词短语，而最后是不定式短语，help for our study指的是不定式短语to have a break at the weekends，因此这个不定式是动词think的宾语，故空格中应填一个形式主语；而选项中可以用作形式主语是it，因此A为正确答案。

In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .

A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .

Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .

So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .

Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .
