Instead he has been told to wait until he is 18.The 16-year-old boy works for a
2、 small firm in Pittsburgh, where the problem of most young people of his age is finding a job. Kevins firm releases (发布) two new games for the home computer market each month.But Kevins biggest headache is what to do with his money. Though Kevin earns a lot of money, he cannot drive a car, or buy a
3、house, or obtain (获得) credit cards.He lives with his parents in Pittsburgh. His company has to pay $200 a month in taxi fares (费用) to get him five miles to work and back every day because Kevin cannot drive.“I got this job because the people who run the firm knew I had already written some programs,
4、“ Kevin said. Most of Kevins spare time is spent working. “Unfortunately, computing was not part of our studies at school,“ he said, “But I had been studying it in books and magazines for years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in thi
5、s business are fairly young anyway.“Kevin added, “I would like to earn a million and I suppose early retirement (退休) is a possibility. You never know when the market might disappear.“(分数:20.00)(1).Kevins great problem is _. A. how to spend his money B. how to design new computer games C. how to lear
6、n to drive D. where to find a bank that will treat him as an adult(分数:5.00)A.B.C.D.(2).Kevin was employed by the company because _. A. he had worked in a computer shop B. he had written some computer programs C. he had worked very hard D. he had learned to use computers at school(分数:5.00)A.B.C.D.(3)
7、.Kevin left school because _. A. he did not enjoy school B. he was afraid of getting too old to start computing C. he wanted to work with computers and staying at school did not help him D. he wanted to earn a lot of money(分数:5.00)A.B.C.D.(4).Why does Kevin think he might retire early? A. Because he
8、 has to be young to write computer programs. B. Because he wants to stop working when he is a millionaire. C. Because he thinks computer games might not always sell so well. D. Because he thinks his firm might go bankrupt (破产).(分数:5.00)A.B.C.D.Animals can move from place to place, but plants cannot.
9、 When an animal is attacked, it can run away or fight back. Plants, however, certainly cannot run away, and they lack teeth and claws (爪子). But plants can defend themselves by using both physical and chemical means (方法).Some plants have their own ways to keep animals away. For example, the leaves of
10、 the holly (冬青树) plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches, which is because the lower leaves are easier for most animals to reach.Some plants, such as the oak tree (橡树), have thick and hard leaves
11、that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animals teeth.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 incr
12、easing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine (尼古丁). The higher levels of nicotine discourage the caterpillar.Many plants depend on both physic
13、al and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future.(分数:20.00)(1).Why does the holly plant have more spines on t
14、he lower leaves? A. Because most animals are not tall enough. B. Because most animals can get the lower leaves easily. C. Because most animals are not clever enough. D. Because most animals like the lower leaves only.(分数:5.00)A.B.C.D.(2).In order to defend themselves, oak trees use _. A. chemical me
15、ans B. physical means C. bitter chemicals D. sandy materials(分数:5.00)A.B.C.D.(3).How does tobacco protect itself against an attack from a caterpillar? A. Its leaves fight against the attack by physical means. B. Its roots send a messenger to discourage the caterpillar. C. Its roots increase the prod
16、uction of nicotine when it is attacked. D. Its leaves produce poisonous sand to drive the caterpillar away.(分数:5.00)A.B.C.D.(4).What would be the best title for this passage? A. Plants and Animals. B. How Animals Eat Plant Leaves. C. Attacks and Defenses. D. How Plants Defend Themselves.(分数:5.00)A.B

21、 and Elizabeth too. For the Homes, seeing Doug and knowing he was well seemed to ease (减轻) their suffering.
