单选题Years ago, a young man named Jason married a beautiful woman. They lived with the man's extended family, that is, his parents, his brothers, as well as their wives and children. In their house an elephant was raised, in which the woman soon showed great interest. She fed fruit and food to it each day. However, just three months later, after having a fight with her husband, the young woman returned to her own parents' home. It was quite surprising that the elephant began to refuse to work or even to eat food. It seemed that it was sick and heart-broken. Finally, one morning after several weeks, it disappeared ! It went to the woman's house to see her. As soon as it saw her, the elephant touched her softly with its nose. So moved was the woman that she went back to her husband's house. This story illustrates that animals are as emotional as human beings. They could do the things you have ever done for them, especially the good aspects. Remember to be kind to them, for we are friends.

单选题Every year landslides (滑坡) cause 25 to 50 deaths and $1.5 billion in damage in the United States. They account for 15 percent of the deaths from natural disasters in Europe. And in December, a single event killed more than 200 people in the Philippines. Sending workers to stabilize mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties. Shaking drills produce harmful dust and loosen heavy, dangerous debris (岩屑). "It's quite a risky job, "says Giorgio Pezzuto of D'Appolonia, an engineering company in Italy. D'Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber. "The idea is to operate a machine far away that can drill without a human being on board," says Pezzuto, the manager for the project, which is supported by the European Commission. Engineers claim that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged mechanical spider, has cost at least $2 million so far. The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the stability. Testing should begin in May.

单选题Tobacco You most likely know that tobacco is a plant. It has large leaves that have been smoked in many forms or at least 2000 years. But do you know that: Before the twentieth century, not many people died from using tobacco because there wasn't much tobacco being used. Cigarettes had to be roiled by hand. A person who was really fast could roll about four cigarettes a minute, or around 2000 a day. In 1884 the cigarette manufacturing machine was invented that could produce 120000 cigarettes a day. Soon the number being sold rose to one billion a year. As a result of advertising and efficient machines, the tobacco business continued to grow. Today about 840 packs of cigarettes are sold every second in the US. That's more than one million every hour! Imagine that! Blink you eyes and 840 packs are sold. Blink again — another 840 packs! As the number of cigarette sales increased, so did the number of deaths caused by cigarettes. Today one out of every five people who die in the US dies because of smoking. Smoking tobacco is responsible for more deaths than cocaine, heroin, alcohol, fire, automobile accidents, homicides, suicides, and AIDS combined. That amounts to about 430000 people who die needlessly every year, 1200 people who die every day because of their addiction to cigarettes. It's like having several completely full jumbo jets crash every day, killing all aboard! Who in the USA Smokes Cigarette smoking is a widespread habit in the United States today. About forty-three percent of the adult men and thirty-one percent of the adult women smoke regularly. It is quite encouraging to note, however, that millions of people have given up the smoking habit. Seventy-five percent of the male population and forty-six percent of the female population have smoked cigarettes at some time during their lives, but twenty-six percent of these men and eleven percent of these women have stopped smoking. The number of persons who have given up smoking is increasing. Men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is the age group 24～44. Income, education and occupation play a part in determining a person's smoking habits. City people smoke more than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, if a well-educated man with a higher income smokes at all, he is likely to smoke more packs of cigarettes every day. The situation is somewhat different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower educational groups. These more highly educated women tend to smoke more heavily. Among teenagers the picture is similar. There are fewer teenage smokers from upper-income, well-educated families, and from families living in farm areas. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.
