【文章內(nèi)容簡(jiǎn)介】 0。North American black bears are shy animals. They are fearful by nature, and will usually run away if they see or hear people. Because of this, it can be difficult for scientists to learn about these animals. In order to study black bears, researchers from New Jersey, the US, catch bears and use drugs to help them go to sleep. Researchers then work out the size and the weight of the bears, take blood, to test for diseases, remove a tooth and take it to the lab to find out its age. From these studies, researchers want to find out how many bears live in New Jersey, how long they live, and how many babies they produce. But in Minnesota, the US, researchers study bears that are pletely awake. The bears know the researchers39。 voices and they are not afraid of the research team. With the help of a few grapes to keep the bears busy, researchers can touch them to check their hearts, look at their teeth, and do other jobs. Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives. In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But the research methods and the kinds of information that researchers are able to collect are quite different.（1）In the first paragraph, we can learn that North American black bears are __________. A.shy and fearful animalsB.not found todayC.well known to scientistsD.not afraid of people（2）The word remove in the second paragraph probably means in Chinese.

A.The age.B.The way of their munication.C.The weight.D.The number of babies they produce.（4）In the Minnesota studies, researchers ________. A.can never get close to the bearsB.study the bears while they are asleepC.use grapes to make the bears fullD.learn a lot about the bears39。 everyday lives8．閱讀理解 There are many wetlands in China and some of them have bee the world39。s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home to many different kinds of animals. The world39。s largest Milu Deer Nature Reserve 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 Redcrowned Crane 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. Offering（提供） food and home to some special kinds of animals 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 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.（1）The Chinese Yellow Sea Wetlands are in the of China. A.eastB.southC.westD.north（2）Usually the weather in the wetlands is . A.hotB.pleasantC.coldD.dry（3）The World Wetlands Day is on . A.April 22B.June 25C.February 2D.March 22（4）We must protect wetlands because . A.they are home to wildlifeB.they can offer food to animalsC.they can prevent floodD.A, B and C9．閱讀理解 Do you read advice columns（建議專(zhuān)欄） in newspapers and magazines? Do you think they are helpful to everyone who reads them? Here are some. Dear Sally, I39。ve got a problem. My good friend Lana in my science class asked me to lend her my exercise book so she could copy my answers. Should I do it, Sally? I don39。t want to, but I39。m afraid that if I don39。t give it to her she won39。t be my friend any longer. CarmenDear Carmen, Of course you can39。t give her your exercise book. That39。s cheating, and you could get into big trouble if you do that. SallyDear Sally, I was at my friend39。s house for dinner last Saturday. During dinner, I broke a beautiful plate. It was my friend39。s favorite plate. It was my friend39。s favorite wedding gift. I wanted to pay for it, but she didn39。t agree with me. I feel bad about it. KayDear Kay, I think you did the right thing. It was important to offer to pay for it, but it39。s not surprising that she said no. Perhaps you could give her a special gift instead. SallyDear Sally, My son is 24 years old. He finished college last year, but he can39。t seem to find a job that he likes. I39。m worried that he39。s not trying hard enough to get a job and live o
