[单选题]In the college-admissions wars, we parents are the true fighters. We're pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice. I've twice been to the wars, and as I survey the battlefield, something different is happening. We see our kids' college background as a prize demonstrating how well we've raised them. But we can't acknowledge that our obsession is more about us than them. So we've contrivedvarious justifications that turn out to be half-truths, prejudices or myths. It actually doesn't matter much whether Aaron and Nicole go to Stanford.
We have a full-blown prestige panic; we worry that there won't be enough prizes to go around. Fearful parents urge their children to apply to more schools than ever. Underlying the hysteria is the belief that scarce elite degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All that is plausible--and mostly wrong. We haven't found any convincing evidence that selectivity or prestige matters. Selective schools don't systematically employ better instructional approaches than less selective schools. On two measures--professor's feedback and the number of essay exams--selective schools do slightly worse.
By some studies, selective schools do enhance their graduates' lifetime earnings. The gain is reckoned at 2-4% for every 100-point increase in a school's average SAT scores. But even this advantage is probably a statistical fluke. A well-known study examined students who got into highly selective schools and then went elsewhere. They earned just as such as graduates from higher-status schools.
Kids count more than their colleges. Getting into Yale may signify intelligence, talent and ambition. But it's not the only indicator and, paradoxically, its significance is declining. The reason:
so many similar people go elsewhere. Getting into college isn't life's only competition. In the next competition--the job market and graduate school--the results may change. Old-boy networks are breaking down. Princeton economist Alan Krueger studied admissions to one top Ph.
D. program. High scores on the GRE helped explain who got in; degrees of prestigious universities didn' t.
So, parents, lighten up. The stakes have been vastly exaggerated. Up to a point, we can rationalize our pushiness. America is a competitive society; our kids need to adjust to that. But too much pushiness can be destructive. The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment. One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction. They may have been so conditioned to being on top that anything less disappoints.
Why do parents urge their children to apply to more schools than ever?
A.They want to increase their children's chances of entering a prestigious college.
B.They hope their children can enter a university that offers attractive scholarships.
C.Their children will have a wider choice of which college to go to.
D.Elite universities now enroll fewer students than they used to.

[简答题]
Even though she was blind and deaf, Helen Keller was a woman with an extraordinary social vision. 61) When most women’s rights activists were working for the right to vote, Helen Keller advocated action that was more direct and more immediate than the vote. In 1911, speaking in England where women had the right to vote, she said: "Our democracy is but a name. We vote What does that mean It means that we choose between two bodies of real, though not avowed, autocrats... You ask for votes for women. 62) What good can votes do when ten-eleventh of the land of Great Britain belongs to 200,000 men and only one-eleventh to the rest of the 40,000,000 Have your men with their millions of votes freed themselves from this injustice"
63) When she became active and openly socialist, a New York city newspaper, the Brooklyn Eagle, which had previously treated her as a heroine, criticized that her misguided socialism had somehow developed from her blind

About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table, I couldn’t help overhearing parts of their conversation. At one point the woman asked: "So, how have you been" And the boy--who could not have been more than seven or eight years old--replied. "Frankly, I’ve been feeling a little de pressed lately."
This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn’t find out we were "depressed" until we were in high school.
The evidence of a change in children has increased steadily in recent years. Children don’t seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to.
Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was

B. the poor arrangement of teaching content
C. the fast pace of human intellectual development
D. the constantly rising standard of living
