5．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 75% using a simple optical illusion．But 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（基金会） 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 （too great） speed plays a major role in as much as one fifth of all fatal traffic accidents，according to the foundation．To help reduce those accidents，the foundation will conduct its tests in areas where speed-related hazards （danger） 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．

78．The passage mainly discussesA．
A．a new way of highway speed control
B．a new pattern for painting highways
C．a new way of training drivers
D．a new type of optical illusion
79．On roads painted with chevrons，drivers tend to feel thatC．

80．The advantage of chevrons over straight，horizontal bars is that the formerD．
A．can keep drivers awake
B．can cut road accidents in half
C．will look more attractive
D．will have a longer effect on drivers
81．The American Automobile Association Foundation forTraffic Safety plans toA．

4．Among various programs，TV talk shows have covered every inch of space on daytime television．And anyone who watches them regularly knows that each one is different in style（风格）．But no two shows are more opposite in content，while at the same time standing out above the rest，than the Jerry Springer and the Oprah Winfrey shows．
Jerry Springer could easily be considered the king of"rubbish talk"．The contents on his show are as surprising as can be．For example，the show takes the ever-common talk show titles of love，sex，cheating，and hate，to a different level．Clearly，the Jerry Springer show is about the dark side of society，yet people are willing to eat up the troubles of other people's lives．
Like Jerry Springer，Oprah Winfrey takes TV talk show to its top．But Oprah goes in the opposite direction．The show is mainly about the improvement of society and different quality（质量） of life．Contents are from teaching your children lessons，managing your work week，to getting to know your neighbors．
Compared to Oprah，the Jerry Springer show looks like poisonous waste being poured into society．Jerry ends every show with a"final word"．He makes a small speech about the entire idea of the show．Hopefully，this is the part where most people will learn something very valuable．
Clean as it is，the Oprah show is not for everyone．The show's main viewers are middleclass Americans．Most of these people have the time，money，and ability to deal with life's tough problems．Jerry Springer，on the other hand，has more of a connection with the young adults of society．These are 18-to-21-year-olds whose main troubles in life include love，relationship，sex，money and drug．They are the ones who see some value and lessons to be learned through the show's exploitation．

74．Compared with other TV talk shows，both the Jerry Springe and the Oprah Winfrey areB．
A．more interesting    B．unusually popular    C．more detailed    D．more formal
75．Though the social problems Jerry Springer talks about appear unpleasant，people who watch the showsA．
A．remain interested in them    B．are ready to face up to them
C．remain cold to them          D．are willing to get away from them
76．Which of the following is likely to be a topic of the Oprah Winfrey show？C
A．A new type of robot．
B．Nation hatred．
C．Family income planning．
D．Street accident．
77．We can learn from the passage that the two talk showsD．
A．have become the only ones of its kind
B．exploit the weaknesses in human nature
C．appear at different times of the day
D．attract different people．

3．A characteristic of American culture that has become almost a tradition is to respect the self-made man-the man who has risen to the top through his own efforts，usually beginning by working with his hands．While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker，he may take pains to point out that his father started life in America as a farmer or laborer of some sort．
This attitude toward manual labor is now still seen in many aspects of American life．One is invited to dinner at a home that is not only comfortably but even luxuriously  furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel，expensive hobbies，and college education for the children； yet the hostess probably will cook the dinner herself，will serve it herself and will wash dishes afterward，furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery．On the contrary，the hostess usually takes pride in careful preparation of special dishes．A professional man may talk about washing the car，digging in his flowerbeds，painting the house．His wife may even help with these things，just as he often helps her with the dishwashing．The son who is away at college may wait on table and wash dishes for his living，or during the summer he may work with a construction gang on a highway in order to pay for his education．

70．From paragraph 1，we can know that in AmericaA．
A．people tend to have a high opinion of the self-made man
B．people can always rise to the top through their won efforts

D．serve customers in a restaurant
73．Which of the following may serve as the best title of the passage？B
