2. Passage Twenty-Two Though some people have suggested that women should return to housework in order to leave more jobs for men， the idea has been rejected by both women and men in public opinion polls (民意测验). Lately some union officials have suggested that too many women are employed in type of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women—especially women in their childbearing years actually delay economic development and result in lower productivity， poor quality and inefficiency. To solve the problem， they have suggested that the working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances， families would retain their same level of income， and women could run the house and raise children much better. The suggestion has been rejected by 9 out of 10 people polled. A hundred persons in a big city were questioned last summer. Out of 50 women， 46 said they were unwilling to leave their jobs， no matter what the situation was. The other 4 said they would like to return home if their jobs could be taken by their sons or daughters. Of 50 men polled， only 6 said they would like to see their wives give up their jobs， if it meant higher wages for themselves. Some other people have suggested another way called “phased employment theory” . The theory suggests that a woman worker take leave from her job when she is seven months pregnant (妊娠) and stay off the job until her baby reaches the age of 3. It suggests that women on leave receive 75 percent of their normal salary and be allowed to return to work after the 3-year period. This will benefit children， women， their families and the society. Some of those polled， both women and men， felt the idea is a good one. It definitely seems to be more acceptable than the suggestion that women return to home forever. Some union officials have suggested that if women resign their jobs， ( ) .

4. Passage Nineteen A 3-year-old boy who was lost in the woods for two days is now safe at home. But Casey Hathaway told his rescuers that he was not alone in the rainy， freezing cold woods. He said he was with a friend——abear. The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina. When the other children returned to the house and Casey did not， the family searched the area for almost an hour before calling the police. Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still——no Casey. The woods of North Carolina are home to many black bears， like this one. It seems one of them helped a little boy while he was lost in the woods. Then on January 24， someone called the police saying they heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. They pulled him out of some briar (荆棘). He was in good health. Police Officer Chip Hughes said that Casey did not say how he was able to survive in the woods for two days in the cloud， rainy weather， but that “he did say he had a friend in the woods that was a bear that was with him. ” Hundreds of people helped in the search and rescue efforts， including some 600 volunteers， federal police and members of the military. Hughes told reporters that at no point did he think Casey had been kidnapped (绑架). Doctors at Carolina East Medical Center treated Casey for minor injuries. He was then released to his family on January 25 .When found in the woods， Casey was ( ) .

A. playing with a bear

B. badly injured by a bear

C. hiding in some briar

D. in good condition

1. Passage Two When older people can no longer remember names at a cocktail party， they tend to think that their brainpower is declining. But a growing number of studies suggest that this assumption is often wrong. Instead，the research finds， the aging brain is simply taking in more data and trying to examine carefully a lot of information， often to its long-term benefit. Some brains do deteriorate with age. But for most aging adults， researchers say， much of what occurs is a gradually widening focus of attention that makes it more difficult to get hold of just one fact. Although that can be frustrating， it is often useful. “It may be that distractibility is not， in fact， a bad thing，” said Shelley H. Carson， a psychology researcher at Harvard. “It may increase the amount of information available to the conscious mind. ” For example， in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases， adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean， older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling (结结巴巴地念) over the extra information， but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers， the older adults responded much better than the students. “For the young people， it’s as if the distraction never happened，” said a researcher of the review， Lynn Hasher， a professor of psychology at the University of Toronto. “But for older adults， because they’ve retained all this extra data， they’re now suddenly the better problem solvers. They can transfer the information they’ve soaked up from one situation to another.” Such tendencies can yield big advantages in the real world， where it is not always clear what information is important， or will become important. For instance， a seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes. According to the first paragraph， it can be inferred that ( ) .
