1、精选优质文档-倾情为你奉上说明文类 Water goes around and around Earth in a never ending journey called the water cycle（循环）. The sun heats up lakes, oceans, and other wet places on Earth. When the water gets warm enough, it changes into vapour. Plants also give off lots of water vapour. Some of this water vapour cool

2、s off high in the sky and becomes clouds. Then it falls back to Earth in a new place as rain or snow. This cycle happens over and over again. The ground can absorb water like a sponge (海绵). If you could see this groundwater, it wouldnt look like a lake or river. The groundwater is mixed in with the

3、rocks and sand that lie in layers(层) below Earths surface. Groundwater moves along slowly. How slowly? Maybe 1.5 kilometres in one century. Some of this water has been underground for thousands of years. And once groundwater is pumped out of the ground from a deep well（井） by people, it may take hund

4、reds of years for another water to take its place.35.In which order does water go around Earth? a .Fall down as rain or snow. b. Heated up by the sun on lakes, oceans and other wet places. c.

7、ation for weather forecasts is sent by satelliteSome satellites have cameras which take photographs of the Earth to show how clouds are movingSatellites are also used to connect our international phone callsComputer connections of the World Wide Web and Internet also use satellites. Many of our TV p

8、rograms come to US through satellitesAirplane pilots also sometimes use a satellite to help them find their exact locationWe use satellites to send television pictures from one part of the world to anotherThey are usually 35，880 kilometers above the equatorSometimes we can see a satellite in the sky

9、 and it seems to stay in the same placeThis is because it is moving around the world at 11，000 kilometers an hourexactly the same speed that the earth rotatesA satellite must orbit the Earth with its antennae(天线)facing the earthSometimes, it moves away from its orbit，So there are little rockets on i

10、t which are used to put the satellite back in the right positionThis usually happens about every five or six daysSpace is not empty! Every week, more and more satellites are sent into space to orbit the EarthA satellite usually works for about 10-12 yearsSatellites which are broken are sometimes rep

11、aired by astronauts or sometimes brought back to Earth to be repairedOften，very old or broken satellites are left in space to orbit the Earth for a very long timeThis is very serious because some satellites use nuclear power and they can crash into each other1Which of the following is NOT done by sa

16、), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.Garlands research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “Theres nothing that has t

17、his ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public

18、 Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the

19、safety guidelines established by the National Academy of Sciences.The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.“African Americans, who dont produce as much of the vitamin because of their ski

20、n colour, could also benefit significantly from a higher intake,” the authors said.1According to the passage, people are advised to take more Vitamin D, because_.A. it is nutritious B. it cant harm peoples healthC. it can lower cancer risk D. it is not taken enough every day2Which of the following c

23、population. It is estimated that over 35 million Americans have physical, mental, or other disabilities. About half of these disabilities are “developmental, i.e., they occur before the individuals twenty-second birthday, often from genetic conditions, and are severe enough to affect three or more a

24、reas of development, such as mobility, communication, employment, etc. Most other disabilities are considered “adventitious, i.e., accidental or caused by outside forces.Prior to the 20th century, only a small percentage of people with disabilities survived for long. Medical treatment for these disa

25、bilities was unavailable. Advancements in medicine and social services have created a climate in which people with disabilities can expect to have such basic needs as food, shelter, and medical treatment. Unfortunately, these basics are often not available. Civil liberties such as the right to vote,

26、 marry, get an education, and gain employment have historically been denied on the basis of disability.In recent decades, the disability rights movement has been organized to fight against these infringements（违反；侵犯）of civil rights. Congress responded by passing major legislation recognizing people w

27、ith disabilities as a protected class under civil rights statutes.Still today, people with disabilities must fight to live their lives independently. It is estimated that more than half of qualified Americans with disabilities are unemployed, and a majority of those who do work are underemployed. Ab

28、out two-thirds live at or below the official poverty level.Significant barriers, especially in transportation and public awareness, prevent disabled people from taking part in society. For example, while no longer prohibited by law from marrying, a person with no access to transportation is effectiv

29、ely excluded from community and social activities which might lead to the development of long-term relationships.Only when public attitudes advance as far as laws have will disabled people be fully able to take their rightful place in society.1.

30、over time B. is caused by forcesC. occurs in youth and affects development D. is getting more and more severe2Most disabled people used to die early because _.A. disabilities destroyed major bodily functions B. they were not very well looked afterC. medical techniques were not available D. they were

Which of the following c

32、annot be inferred（推断）from the passage ?AMany disabled people may remain single for their whole life.BThe public tends to look down upon the disabled people.CThe disabled people feel inferior to those surrounding them.DDiscriminatory laws prevent the disabled from mixing with others.5. The best title for this passage might be _.AHandicaps（不利条件；障碍；）of People with Disabilities BThe physical difficulties of the DisabledCThe Causes for DisabilitiesDMedical Treatments for Disabilities 1-5 CCBDA专心-专注-专业
