1、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 cools off high in

2、 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 rocks and san

3、d 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 hundreds of years

Many of our TV programs come

16、et or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.Garland's 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. “There's nothing that has this

17、 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 He

18、alth. 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 saf

19、ety 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 don't produce as much of the vitamin because of their s

20、kin 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

23、e 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 individual's twenty-second birthday, often from genetic conditions, and are severe enough to affect th

24、ree or more areas 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 treat

25、ment for these disabilities 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

26、 the right to vote, 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 r

27、ecognizing people with 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 ar

28、e underemployed. About 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 transpo

29、rtation is effectively 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. A “developmental" disability _.A. develops very slowly over time B. is caused by forcesC. occurs in youth and affects development D. is getting more and more severe2Most d
