单选题Dina Borzekowski made a study of a group of third-grade students from six American schools. During a school year, nearly 400 students and their parents were asked to report on whether they had such things as televisions and computers in the home, as well as how often the child used them. The children"s language ability was tested (测验) twice over the year. Children who had a television set in the bedroom but did not have a computer at home scored (得分) the lowest, while students without TV in the bedroom but with a computer at home scored the highest. Students who had a television in the bedroom over the school year scored lower than those who had their TV taken away during the same time. "This study suggests that taking TV sets out of children"s bedrooms, or not putting them there, may be helpful," said Borzekowski. "While this study does not prove (证明) that bedroom TV was the reason for the lower test scores, it suggests that children shouldn"t have TV in their bedrooms. It also suggests that a home computer may help a child"s test scores. The best way was having no TV in the bedroom and also a home computer to use.

单选题Some people do not like anything to be out of order. They are never late for work; they return their books to the library on time; they remember people's birthdays; and they pay the bills as soon as they arrive. Mr Dodds was such a person. Mr Dodds worked in a bank, but lived alone. Tile only family he had was in the next town, where his sister lived with her husband and their son, Mark. Mr Dodds had not seen his sister or her family for some years, but he sent them Christmas cards every year, and he had not forgotten Mark's seventeenth birthday days before. Last week,Mx Dodds had quite a surprise. He drove home form the bank at the usual time and drove neither too slowly nor too fast; he parked his car where he always parked it, and went inside to make his evening meal. Suddenly, there was a knock at the door. Mr Dodds opened the door, and found a policeman standing there. "What have I done wrong?" Mr Dod& asked himself. "Have I driven on the wrong side of the road? Has there been some trouble at the bank7" "Hello, Uncle," said the policeman, "My name's Mark./
