In the 13th century, the famous 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 didn’t use paper money until 15th century. However, people in China began to use paper money in the 7th century.

A Chinese man called Cai Lun invented (发明) paper almost 2,000 years ago. He put these pieces of paper together and made them in a book.

Now paper 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 left on the earth. If there are no trees, there will be no paper. So how can we save paper? We can use both of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets (小包). We can also use handkerchiefs (手帕) and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give you 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. We should do it now, before it is too late.

文章大意:本文是一篇说明文。文章主要讲了罗伯特·怀特博士,一位著名的教授和医生,认为他知道一种帮助大脑损伤手术的方法。他认为医生应该让大脑变得非常冷。如果天气很冷,大脑可以在没有血液的情况下存活30分钟。这就给了医生更长的时间来治疗大脑。

【推荐2】It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.

Dr Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctors a longer time to do something for the brain.

Dr White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

文章大意:本文介绍了空降消防员是谁以及他们做什么。

【推荐3】Every year, wildfires destroy millions of hectares of forest land. Homes are damaged, and thousands of people die. Smokejumpers help to stop this.

Smokejumpers are a special type of firefighter. They jump from planes or are lowered by helicopters into areas that are difficult to reach by car or on foot, such as the middle of a mountain forest. They race to put out fires as fast as they can.

At a fire site, smokejumpers first examine the land and decide how to fight the fire. Their main goal is to stop a fire from spreading or to slow its progress until full, ground-based firefighters arrive. Using basic equipment such as shovels and axes, smokejumpers clear land of burnable material, like dry grass and dead trees. They carry water with them, too, but only a limited amount.

Although the majority of smokejumpers are men, more women are joining now. The most important factors are height and weight. Smokejumpers employed in the United States, for example, must be between 54 and 91 kilograms so they don’t get blown away by the strong winds or get hurt when they land. Smokejumpers must be also capable of surviving in the wildness. In Russia, many smokejumpers know how to find food in the forest and can even make simple furniture from trees.

The work is dangerous, and the hours are long. But for these firefighters, smokejumping isn’t just a job. They love being able to jump out of planes, fight fires, and live in the forest. As a 28-year-old Russian smokejumper Alexi Tishin says, “This is the best job for tough guys.”

1. The reading is mainly about ________.
A.the life of a Russian smokejumperB.who smokejumpers are and what they do
C.why people become smokejumpersD.how to become a professional smokejumper
2. When smokejumpers reach a fire site, the first thing they do is ________.
A.looking for waterB.clearing the land
C.studying the landD.connecting ground-based firefighters
3. If you want to be a smokejumper, you must be ________.
A.maleB.a university graduate
C.within a certain weight rangeD.know how to cook food in the forest
4. Which of the following is NOT true for smokejumpers?
A.They must learn to fly a plane or helicopter.
B.They must learn to survive in the wildness.
C.They put out fires in areas that are hard to reach.
D.They must be brave enough to jump from high places.
5. In Alexi Tishin’s opinion, smokejumpers do the job ________.
