Part 7 Reading Comprehension (Multiple Choice)
(每小题：分)
Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D.
Questions 1 to 5 are based on the following passage.
The decline in moral standards—which has long concerned social analysts—has at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad.
The fact that ordinary citizens are now starting to think seriously about the nation's moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.
But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. "The thought that 'I'm in it for me' has become deeply rooted in the national consciousness," Ms. Elshtain says.
Some of this can be attributed to the decay of traditional communities, in which neighbors looked out for one another, she says. With today's greater mobility and with so many couples working, those bonds have been weakened, replaced by a greater emphasis on self.
In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the US. And Elshtain says the public is correct to sense that: Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and a high rate of births to unmarried mothers.
The desire for a higher moral standard is not a lament (挽歌) for some nonexistent "golden age," Elshtain says, nor is it a wishful (一厢情愿的) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor a decrease in prejudice.
Moral decline will not be reversed until people find ways to counter the materialism in society, she says. "Slowly, you recognize that the things that matter are those that can't be bought."
1.Professor Elshtain is pleased to see that Americans ________.
A. have adapted to a new set of moral standards
B. are longing for the return of the good old days
C. have realized the importance of material things
D. are awakening to the lowering of their moral standards
2.The moral decline of American society is caused mainly by
________.
A. its growing wealth
B. the self-centeredness of individuals
C. underestimating the impact of social changes
D. the prejudice against women and minorities
3.Which of the following characterizes the traditional
communities?
A. Great mobility.
B. Emphasis on individual effort.
C. Concern for one's neighbors.
D. Ever-weakening social bonds.
4.In the 1950s, classroom violence ________.
A. was something unheard of
B. attracted a lot of public attention
C. was by no means a rare occurrence
D. began to appear in analysts' data
5.According to Elshtain, the current moral decline may be
reversed ________.
A. if people can return to the "golden age"
B. when women and men enjoy equal rights
C. when people rid themselves of prejudice
D. if less emphasis is laid on material things
Questions 6 to 10 are based on the following passage.
For an increasing number of students at American universities, old is suddenly in. The reason is obvious: the graying of America means jobs. Coupled with the aging of the baby-boom (生育高峰) generation, a longer life span means that the nation's elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses serious questions for government and society, of course. But it also creates career opportunities in medicine and health professions, and in law and business as well. "In addition to the doctors, we're going to need more sociologists, biologists (生物学家), city planners and specialized lawyers," says Professor Edward Schneider of the University of Southern California's (USC) School of Gerontology (老年学).
Lawyers can specialize in "elder law", which covers everything from trusts and estates to nursing-home abuse and age discrimination (歧视). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. "Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money," one professor says.
Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was "really bored with bacteria". So she took a class in gerontology and discovered that she liked it. She says, "I did volunteer work in retirement homes and it was very satisfying."
6.The words "... old is suddenly in" (Para. 1) most probably
means "_______".
A. America has suddenly become a nation of old people
B. gerontology has suddenly become popular
C. more elderly professors are found on American campuses
D. American colleges have realized the need of enrolling older
students
7.With the aging of America, lawyers can benefit _______.
A. from the adoption of the "elder law"
B. from rendering special services to the elderly
C. by enriching their professional knowledge
D. by winning the trust of the elderly to promote their own
interests
8.Why can businessmen make money in the emerging elder
market?
A. Retirees are more generous in spending money.
B. They can employ more gerontologists.
C. The elderly possess an enormous purchasing power.
D. There are more elderly people working than before.
9.Who can make big money in the new century according to the
passage?
A. Retirees who are business-minded.
B. The volunteer workers in retirement homes.
C. College graduates with an MBA or law degree.
D. Professionals with a good knowledge of gerontology.
10.It can be seen from the passage that the expansion of
America's elderly population ________.
A. will provide good job opportunities in many areas
B. will impose an unbearable burden on society
C. may lead to nursing home abuse and age discrimination
D. will create new fields of study in universities

The so-called "mean" by Confucius doesn't mean "compromise" but a "moderate" and "just-right" way when understanding and handling objective things. Confucius advocated that this thought should not only be treated as a way to understand and deal with things but also be integrated into one's daily conduct to make it a virtue through self-cultivation and training. The Doctrine of the Mean is not only the core of Confucianism but also an important component of traditional Chinese culture. From the time it came into being to the present, it has played an invaluable role in the construction of national spirit, the transmission of national wisdom, and the development of national culture.
