18、s showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet 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

19、D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this 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 Can

20、cer Center team that published its findings this week online in the American Journal of Public 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 supplemen

21、t to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the 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

29、 most growing plants.Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose h

30、orns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has todaya person who is new in a job.Someone who has the ability to grow plants well is said to have a green thumb. The e

31、xpression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.The Green Revolution is the name gi

32、ven some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The gr

33、een-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”.

41、ot;, i.e., they occur before the individual's twenty-second birthday, often from genetic conditions, and are severe enough to affect three or more areas of development, such as mobility, communication, employment, etc. Most other disabilities are considered “adventitious", i.e., accidental

42、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 disabilities was unavailable. Advancements in medicine and social services have created a climate in which people with disabilities can expect to

43、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, marry, get an education, and gain employment have historically been denied on the basis of disability.In recent decades, the disability right

44、s movement has been organized to fight against these infringements（违反；侵犯）of civil rights. Congress responded by passing major legislation recognizing people with disabilities as a protected class under civil rights statutes.Still today, people with disabilities must fight to live their lives indepen

45、dently. It is estimated that more than half of qualified Americans with disabilities are unemployed, and a majority of those who do work are underemployed. About two-thirds live at or below the official poverty level.Significant barriers, especially in transportation and public awareness, prevent di

46、sabled people from taking part in society. For example, while no longer prohibited by law from marrying, a person with no access to transportation is effectively excluded from community and social activities which might lead to the development of long-term relationships.Only when public attitudes ad

47、vance 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 timeB. is caused by forcesC. occurs in youth and affects developmentD. is getting more and more severe2Most disabled people used to

In the author's opinion, to enable the disabled people to take their rightful place in society, _.Am

49、ore laws should be passedBpublic attitudes should be changedCgovernment should provide more aidsDmore public facilities should be set up4. Which of the following cannot be inferred（推断）from the passage ?AMany disabled people may remain single for their whole life.BThe public tends to look down upon t

50、he disabled people.CThe disabled people feel inferior to those surrounding them.D Discriminatory 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 DisabilitiesBThe physical difficulties of the DisabledCThe Causes for Di

51、sabilitiesDMedical Treatments for DisabilitiesFAnimals can move from place to place, but plants cannot. When an animal is under attack, itcan run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. Butplants can defend themselves by using both physical and chemical m

52、eans.      Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower le

53、aves are easier for most animals to reach.      Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth. 

54、60;    Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf pr

55、oduces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.      Many plants depend on both physical and chemical defenses. A certain plant in China, forinstance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single ex
