【正文】 at danger to spacemen. It39。s reported that there were 9,000 manmade things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion（爆炸） in space in 1999 made a cloud of 300,000fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage（損壞）. Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may bee possible for people to spend a few days in a space hotel. People may even choose to leave the earth and live in space in a few years. So scientists are doing everything they can to help improve the space environment. （1）How many kinds of dangers in space does the passage mention?

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.拔下B.移植C.清洗D.修補(bǔ)（3）Which of the following may NOT be included in the New Jersey studies on black bears? 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 lives14．閱讀理解 Class Three had an interesting class meeting last week.
