问题 The U.S. will come to lose its leading place in technology probably because_______.
  
The United States is on the verge of losing its leading place in the world’s technology. So says more than one study in recent years. (11)The main reason for this decline is the parallel decline in the number of U. S. scientists and engineers. Since 1976, employment of scientists and engineers has gone up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-olds—the near term source of future PhDs—is declining. (12)Further adding to the problem is the increased competition for these candidates from other fields: law, medicine, business, etc. While the number of U. S. PhDs in science and engineering declines, the award of PhDs to foreign nationals is increasing rapidly. Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor’s and Master’s degree holders. (13)Too often, promising PhD candidates, confronting the cost and financial sacrifice of pursuing their education, find the attraction of industry irresistible.

选项 A、they are not encouraged to be engaged in science.
B、industry does not require PhD holders.
C、they won’t earn much money after graduation.
D、they will face the cost and financial sacrifice.

答案D

解析 细节题。文章结尾说很难动员学生继续深造,因为工业需要大量本科和硕士毕业生,对于许多有望继续攻读博士的学生来讲,继续深造就意味着在费用和财力方面必须付出和牺牲。据此推断D为正确答案。
