3、Believe it or not， optical illusion(错觉)can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75percent using a simple optical illusion. Bent stripes， called chevrons (人字形)， painted on the roads make drivers think that they are driving faster than they really are， and thus drivers slow down. Now the American Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japan＇s success. Starting next year， the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes. Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents， according to the foundation will conduct its tests in areas where speed - related hazards are the greatest - curves， exit slopes， traffic circles， and bridges. Some studies suggest that straight， horizontal bars painted across roads can initially cut the average speed of drivers in half. However， traffic often returns to full speed within months as drivers become used to seeing the painted bars. Chevrons， scientists say， not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower.The result is a longer lasting reduction in highway speed and the number of traffic accidents.4.The American Automobile Association Foundation for Traffic Safety plans to()( )

2、In a family where the roles of men and women are not sharply separated and where many household tasks are shared to a greater or lesser extent， notions of male superiority are hard to maintain.The pattern of sharing in tasks and in decisions makes for equality， and this in turn leads to further sharing. In such a hcme， the growing boy and girl lean场accept that equality more easily than did their parents and to prepare more fully for participation in a world characterized by cooperation rather than by the “battle of sexes.” If the process goes too far and man＇s role is regarded as less important that has happened in some cases----we are as badly off as before， only in reverse. lt is time to reassess the role of the man in the American family. We are getting a little tired of “Momism”----but we don＇t want to exchange it for a”neo-Popism.” What we need， rather， is the recognition that bringing up children involves a partnership of equals. There are signs that psychiatrists， psychologists， social workers， and specialists on the family are becoming more aware of the part men pkay and that they have decided that women should not receive all the credit----nor all the blame. We have almost given up saying that a woman＇s place is in the home. We are beginning， however， to analyze man＇s place in the home and to insist that he does have a place in it. Nor is that place irrelevant to the healthy development of the child.The family is a co-operative enterprise for which it is difficult to lay down rules. because each family needs to work out its own ways for solving its own problems. Excessive authoritarianism has unhappy consequences， whether it wears skirts or trousers， and the ideal of equal rights and equal responsibilities is pertinent not only to a healthy democracy， but also to a healthy family.5.According to the author， the solution offamily problems()( )

1、In China it is relatively usual to ask people their age， but in the West this question is generally regarded as impolite. This is particularly true _11()women， and even more so if the inquirer is a man. However， it is very _12()to ask children their age， and some adults may not mind being asked either. In fact， some elderly people are quite happy to _13()their age， especially if they feel they look young for their age. Nevertheless， it is not very wise to ask a direct question like “How old are you?”.If elderly people want to talk about their age， they may easily14()_the topic themselves， and ask the other person to guess how old they are . They normally expect to be complimented on their youthfulness， though rather than()15() that they look very old. Even tbough Westerners do not usually ask people directly how old they are， this does not _16() that they are not interested to know how old other people are. They may ask _17()for the information， or else they may try to 18() the topic indirectly. Sometimes discussions about educational_19()and the number of years of working experience may provide some clues， but this is not always the 20().20.( )
