In the 13th century, the famous Italian traveler, Marco Polo, traveled a long way to China. 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 11th century.
A Chinese man called Cai Lun invented paper almost 2,000 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. ①If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. ②Every day, people all over the world throw away about 2800 tons (噸) of paper. It takes 17 trees to make one ton of paper. This means we are cutting down 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 save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
小題1: 將①處翻譯成漢語。
____________________________________________________________________________
小題2:根據(jù)②處完成下面的句子。（每空一詞）
Every day, about 2800 tons of paper _________ ________ away by people all over the world.
小題3: 根據(jù)短文內(nèi)容完成下面的句子。（每空一詞）
Paper is made from trees, so we should try our best to _________ paper so that we can help ________ the trees.

小題1:如果我們持續(xù)浪費(fèi)這么多的紙，地球上將不會(huì)剩下任何的樹木。
小題2:is thrown
小題3:save,protect

試題分析：這篇文章主要講述了中國人在很久以前發(fā)明了造紙術(shù)，用樹木來制作紙張，現(xiàn)在人們依舊使用這種方法。這也致使了很多樹木被砍，尤其是紙張的浪費(fèi)加劇了這一問題。所以我們應(yīng)該節(jié)約用紙，例如雙面使用，用手帕等。
小題1:if引導(dǎo)一個(gè)條件狀語從句；如果……；短語keep on doing sth.持續(xù)做某事。
小題2:本題就是把句子變成被動(dòng)句，結(jié)構(gòu)為be+動(dòng)詞過去分詞；故填is thrown。
小題3:這篇文章內(nèi)容就是要求人們節(jié)約用紙來保護(hù)樹木，故填save節(jié)約；protect保護(hù)。

What do you think of the most important inventions in the world? The TV? The printing? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.
One of the simplest(最簡單的) inventions is the toilet(沖水式馬桶). Before toilets, waste ran into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.
Animal food is another important invention. Before the invention, most animals were killed（殺死） every autumn because there was not enough food for them in winter.  After hay (干草) became a kind of common animal food, animals could live through the long winter. The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the world would be difficult for the people above 45.
