科目：初中英語 來源： 題型：

　　A study suggests that the United States needs to work on training and keeping scientists.

　　Since 1980, the number of jobs that need science and engineering (S&E) knowledge has increased (增加). And each year in the US, the number of jobs that need S&E skills increases by 5%.

　　In the next 20 years, many talented people with S&E knowledge will retire (退休), because more than half of them now are in their 40s or older and 30% of them are 55 or older. Therefore, to have enough talented people, universities need to train students in S&E. Yet fewer and fewer students are choosing jobs in S&E. In other words, there are not enough new talented people to take the place of the retiring ones, so there will be a gap (缺口) in the future.

　　In the past, the US filled this gap with foreign talented people. These people came to the US to study and got their doctorates (博士學位) from American universities. Many of them lived in the US to use their science skills . In 2001, foreign talented people not more than half of the doctorates in S&E in this country.

　　But the US can’t only depend on foreign talented people. In order to have more Americans with doctorates that work in jobs in S&E, more students need to go to university. However, even though the US is starting to support science, and middle school students are deciding to become scientists, these students will not finish their studies until 2018 or 2020.

　　1. The number of jobs that need S&E skills increases by _________ each year in the US.

　　A. 30% B. 5% C. 40% D. 20%

　　2. According to the passage, which of the following is NOT right?

　　A. In the US many old talented people with S&E knowledge will not retire because they are needed.

　　B. Universities are training students in S&E to have enough talented people.

　　C. A lot of foreign talented people lived in the US to use their science skills.

　　D. Fewer and fewer students are choosing jobs in S&E.

　　3. In the passage the writer thinks that________.

　　A. all the students should study science at university in the US

　　B. foreign talented students get less than half of the doctorates in the US

　　C. the US needs to do something to keep talented people in S&E

　　D. there are too many people in America that need jobs
