    Tigers are strong and dangerous animals. But now they are in danger.
    In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. The number of Siberian tigers (东北虎) was about 300, but now it is less than 22. They’re in danger of dying out. If the government does nothing, we won’t be able to see them in ten to twenty years.
    In order to stop people from hunting and killing wild tigers, and in order to make wild tigers more, the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.
    However, it’s not enough. Remember that nature is a food chain (链). If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger (饥饿). So the most important thing is to save the animals that tigers eat. In order to protect the wild tigers, we need call on (号召) more people to stop eating, hunting and killing wild animals.
    根据短文内容，选择正确答案。
    小题1:During the 20th century, _______ kinds of wild tigers died out.
    A．3B．5C．8D．20

    小题1:A
    小题2:C
    小题3:D
    小题4:B
    小题5:A

    试题分析：老虎是强大而危险的动物，但现在它们正处于危险之中。他们面临灭绝的危险。记住,自然界是食物链。如果我们伤害和杀死太多野生鹿、猪，野生老虎会因为饥饿消亡。所以最重要的是拯救老虎赖以为食的动物。为了保护野生老虎,我们需要停止进食,狩猎和杀害野生动物。
    小题1:细节理解题。 由“In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. （在过去,世界上有八种老虎。但是在20世纪,只剩下五种。）”原来有8种，现在只剩5种了，所以有三种灭绝了，故选A。
    小题2:细节理解题。由“The number of Siberian tigers (东北虎) was about 300, but now it is less than 22.（以前西伯利亚虎的数量(东北虎)约为300,但现在还不到22只。）”由此可推算出，有93%的东北虎死去了。故选C。
    小题3:细节理解题。由“Remember that nature is a food chain . If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger .(记住,自然界是食物链。如果我们伤害和杀死太多野生鹿、猪，野生老虎会因为饥饿消亡。)”老虎以食物链中的猪和鹿为食，没有足够的猪和鹿，就会危及老虎的生存，故选D。
    小题4:细节理解题。由“the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.”可知，是中国和12个其他国家参与了世界自然基金会组织的某个项目，而不是只有12个国家加入世界自然基金会，故选B。
    小题5:主题归纳题。根据文章的介绍可知，作者主要描述了老虎的处境和人们如何采取措施保护老虎，所以选 A（最佳题目是：为何和如何保护老虎）。

    阅读下面的短文，并完成短文后的任务。
    Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
    Waste can bring a lot of problems. Although China is rich in some resources (资源), we are short of others, for example, fresh water. It is reported that we will have no coal（煤） or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. (83) I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
    In our everyday life, we can do many things to prevent (阻止) waste from happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. (84) Waste can be stopped one day, if we do our best.

    On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.
    People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
    　　In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save more people from several illnesses.
    　　Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technology (技术) wasn’t limited (限制) in use.
    小题1:When did we first know why we look like other people in our family?
    A．In 1860.B．In 1953.C．In 1961.D．In 2000.
    小题2:What did the two scientists first discover in 1961?
    A. The “map” of DNA.                     B. A new illness. 
    C. The language of DNA.                   D. A message of DNA.
    小题3:What can we do if we understand some “words” of the language inside the body?
    A．Make people get new jobs.
    B．Make medicine for illnesses.
    C．Make maps of human.
    D．Make people less attractive.
    小题4:What do people think about this work?
    A．It can cause good or bad results.
    B．It can cause only good results.
    C．It can cause good results but won’t work.
    D．It can cause only bad results.

    We all know that smoking is bad for people’s health. But not many people know about the danger of secondhand smoke.
    Secondhand smoke is the smoke that comes from the smoker’s breath(呼吸). If people breathe in secondhand smoke from time to time, they could get sick from it.
    But how serious is the problem of the secondhand smoke? The World Health Organization(WHO) did a study of 194 countries. They found that secondhand smoke causes about 600,000 deaths every year. That is about 1% of the world’s deaths.
    Secondhand smoke is especially bad for children because their bodies are still growing. According to the study, around 165,000 children under the age of 5 die each year because of secondhand smoke. Most of these deaths happen in Africa and southern Asia.
    You can do something to keep yourself and other people away from secondhand smoke. You can ask the smokers, such as your parents, to smoke outside. And, if someone smokes close to you, you’d better hold your breath or just walk away.

    根据短文内容，判断下列句子的正误，正确的用“T”，错误的用“F”。（每小题1分，共5分）

    There are many wetlands (湿地) in China and some of them have become the world's important wetlands.
    The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The world's largest Milu Deer Nature Reserve (自然保护区) is in them. More than 700 Milu deer live freely there. There are not many red-Crowned cranes in the world, but every winter you can see some in the red-Crowned Nature Reserve in the Yellow Sea Wetlands.
    The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife (野生动物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
    Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands. 
    小题1:The Chinese Yellow Sea Wetlands are in the west of China.
    小题2:Usually the weather in the wetlands is pleasant.
    小题3:February 2nd is the world's wetlands Day.
    小题4:We must protect wetlands only because they can offer food to the animals and birds.
    小题5:Wetlands are valuable resources of land on the earth.
