　　重点句子

　　Changes to Come in U.S Education

　　The biggest "infrastructure” challenge for the United States in the next decade is not the billions needed for railroads， highways and energy. It Is the American school system， from kindergarten through the Ph.D. program and the postgraduate education of adults. And it requires something far scarcer than money - thinking and risk-taking.

　　The challenge is not one of expansion. On the contrary， the rapid growth in enrollment over the last 40 years has come to an end. ⑴

　　1.on the contrary， "相反地”

　　注意本句的时态： 用的是现在完成时，因为有一个明显的时间状语over the last 40 years.

　　译：相反，在过去的40年中，学校的在校人数迅速增加的局面已经结束。

　　By 1978， more than 93 percent of young people entering the labor force had at least an eighth-grade education. So even if the birthrate should rise somewhat， little expansion is possible for elementary and secondary school enrollments.

　　The last 30 years of social upheaval are also over. Busing will continue to be a highly emotional issue in a good many large cities. And there will still be efforts to use schools to bring women into fields such as engineering that have traditionally been considered "made.” But this shift has already been accomplished in many fields： half or more of the accounting students in graduate schools of business， for example， are now women.

　　As for most other social issues， the country will no longer try to use schools to bring about social reform. ⑵
