    A caring mother is the single most important factor in preventing teenagers from abusing（滥用）drugs and alcohol，researchers said on Friday．An international study showed that teenagers living with both parents are less likely to suffer from alcohol and drug problems，and a strong maternal bond is the most effective way to fight against them．

   “These findings suggest that living with both parents may prevent drug use．”said Dr．McArdle，of Newcastle University in northern England, who led the study．“They also suggest that attachment（感情眷念），particularly to mothers，is a more effective factor and that this is truly across cultures and substances．”The report, which is published in the journal Addiction, involved nearly 4,000 teenagers in England，Ireland，Italy，Germany and the Netherlands．They were questioned about their use of several kinds of drugs and alcohol．The teenagers also filled in questionnaires about their relationship with their parents and grandparents, how well they were supervised（监护）after school and whether they were allowed to meet friends at home．

   “Both the quality of family relationships and the structure of families have significant influences on youth drug use,” McArdle said in a statement．But he added that a strong maternal bond offered the greatest protection against developing drug habits．The rate of drug abuse among teenagers living with both parents and who had a good relationship with their mother was 16．6 percent．If either factor was missing, the drug abuse rate rose to 32 percent．More than 42 percent of teenagers living in one parent families who did not have a strong bond with their mother used drugs．

   Drug prevention campaigns in British schools and on television warn teenagers about the danger of drugs and alcohol but McArdle said no one is dealing with the problem of their parents’ responsibility

The phrase“maternal bond”appears twice in this passage．Guess its meaning__________．

       A．物质的奖励                B．母亲的约束        

       C．法律的制裁              D．学校的指导

According to McArdle,which is most likely to have the drug abuse problem_________?

       A．16-year-old Tom from a happy big family

       C．18-year-old Juliet living with her single father． 

       D．19-year-old Mark cared by his parents．

Which of the following is NOT mentioned in the passage__________?

       A．Teenagers with both parents won’t have the drug use problem．

       B．Teenagers from several countries filled in the questionnaire．

       C．Teenagers were asked about their relationship with parents．

       D．Teenagers in British schools are warned against drugs abuse．

That year , in the local school, there was a new math teacher, as well as some new pupils. One of the new kids was the stupidest child anyone had ever seen. It made no difference how quickly or how slowly they tried explaining numbers to him; he would always end up saying something enormously stupid. Like two plus two was five, seven times three was twenty-seven, or a triangle had thirty corners……
Before this boy arrived, math lessons had been the most boring of all. Now they were great fun. Encouraged by the new teacher, the children would listen to the pieces of nonsense spouted by the new kid, and they would have to correct his mistakes.
Whenever the new teacher asked questions, the stupid kid would stand up but made the wrong answers, the other students all wanted to be the first to find his mistakes, and then think up the most original ways to explain them. To do this they used all kinds of stuff : sweets, playing cards, oranges, paper planes, etc. It didn’t seem like any of this bothered the new kid.
However, Little Lewis was sure that it was bound to make him feel sad inside. Lewis was sure he would see him crying. So, one day, he decided to follow the new kid home after school. On leaving school, the new kid walked a few minutes to a local park, and there he waited for a while, until someone came along to meet him……
It was the new teacher!

Bob was a clever college student, but his family was poor, so he had to work after class and during his holidays to get enough money for his studies.
One summer he got a job in a butcher’s shop during the day time, and another in a hospital at night. In the shop, he learned to cut and sell meat. He did so well that the butcher went into a room behind the shop to do all the accounts. In the hospital, of course, Bob was told to do only the easiest jobs. He helped to lift people and carry them from one part of the hospital to another. Both in the butcher’s shop and in the hospital, Bob had to wear white clothes.
One evening in the hospital, Bob had to help to carry a woman from her bed to the operating - room. The woman already felt frightened when she thought about the operation. When she saw Bob coming to get her, she felt even more frightened.
"No! No!" she cried. "Not a butcher! I won’t let a butcher operate on me!" with these words ,she fainted away.
