Why has the kiwi survived while its
relatives the moas have become extinct One reason, I think, is that it has
adopted nocturnal(夜间活动的) habits. Kiwis are not normally about in the daytime.
During the daylight hours they lie up in hiding, where enemies have no hope of
finding them. Their coloration protects them; the strange drab(黄褐色的) feathering,
so unlike that of most birds, gives them a cloak(伪装)of invisibility while they
sleep. And when night falls, out they come to scratch in the ground and find
worms and feed to their hearts’ content. They couldn’t do that
so effectively if they didn’t have another peculiarity that I have not mentioned
yet. The nostrils(鼻孔) of most birds open high up near the base of the
beak(猛禽的嘴), but the kiwi wears his nostrils right near the tip of the long bill.
That’s good for a bird that feeds in th A. it stays out of sight and sleeps during the day B. it usually goes from place to place during the day C. it changes the colour of its feather in the daytime D. it is caught and eaten by its enemy in the daytime
[单项选择] Passage Four
American culture has not been immune to
cultural influences from outside. The idea of democracy came from the ancient
Greeks; the Industrial Revolution started in England; jazz and rock music
preserve African rhythms—to pick a few examples. Indeed, many of the things we
think of as "100 percent American" came from other cultures.
Still, most of the changes in American culture over the last century have
come from within, as the result of inventions and discoveries. And change has
been dramatic. One hundred years ago the United States was largely a nation of
farmers. Many of the things we take for granted today—a high school education,
for example, or indoor plumbing—were luxuries then. The moon was a light for
lovers, not a site for scientific exploration; genetic engineering (基因工程) was
not even a subject for science fiction, mu A. talk about the American culture in transition B. criticize the American culture C. state the absurdity of American culture D. talk about the inventions and discoveries

The case for college has been accepted without question for more than a generation. 61) All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become "better" people, and learn to be more responsible citizens than those who don’t go.
But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don’t fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each other’s experiments and write false letters of recommendation in the intense competition for admission to graduate school. 62) Others find no stimulation in their studies, and drop out -- often encouraged by college administrators.
Some observers say the fault is with the young people themselves -- they are spoiled
