Time flies! This is a third year that I have been in this school. In the past two and a half years, our school had organized many activities. What impressed me best was an activity called “Learning to Farm”. In an autumn afternoon, we were sent to a farm which we learned to plant potatoes. Having been in the city for so a long time, we were so happy to go to the countryside. After divided into three groups, we started to work. Some students cut potatoes into pieces; some dug holes, and the others put the pieces of potatoes into the hole, put the earth back and pushed them down hard. We continued doing that until all the work was done. Although we were exhausted, but we felt fulfilled on our way back home.

A recent study, published in last week’s Journal of the American Medical Association, offers a picture of how risky(冒險的) it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a deadly accident as a teenager driving alone, while the risk of death for drivers between 30 and 59 decreases with each additional passenger.
The authors also found that the death rates for teenage drivers increased sharply after 10 p.m., and especially after midnight. With passengers in the car, the driver was even more likely to die in a late-night accident.

Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with “really stupid behavior” than with just a lack of driving experience. “The basic issue,” he says, “is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is.”
Both he and the author of the study believe that the way to mitigate (使……緩解)the problem is to have states set up so-called graduated licensing systems, in which getting a license is a multistage process. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving with night or passenger limits, before graduating to full driving licenses.
Graduated licensing systems have reduced teenage driver crashes, according to recent studies. About half of the states now have some sort of graduated licensing system in place, but only 10 of those states have limits on passengers. California is the strictest, with a new driver under 20 forbidden to carry any passenger (without the presence of an adult over 25) for the first six months.
1.Which of the following situations can we infer is most dangerous according to the passage?
A.A teenager driving after midnight with passengers in the car.
B.Adults giving a lift to teenagers on the highway after 10 p.m.
C.Adults driving with three or more teenage passengers late at night.
D.A teenager getting a lift from a stranger on the highway at midnight.
2.According to Robert Foss, the high death rate of teenage drivers is mainly because of _______.

A.their frequent driving at night

B.their improper ways of driving
C.their driving with passengers

D.their lack of driving experience
3.According to Paragraph 3, which of the following statements is TRUE?
A.The licensing departments are partly responsible for teenagers' driving accidents.
B.Driving is too complex a skill for teenagers to learn.
C.Teenagers should be forbidden to apply to take driving lessons.
D.Teenagers should spend more time learning to drive.

4.A suggested measure to be taken to reduce teenagers' driving accidents is that_______.
A.driving in the presence of an adult should be made a rule
B.the licensing system should be improved
C.they should not be allowed to drive after 10 p.m.
D.they should be forbidden to take on passengers

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (學(xué)術(shù)界) outweigh any financial considerations.

Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few possibilities of a commercial return, and Lee’s is one of them.

The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制藥的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities.

Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (轉(zhuǎn)換) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary (多學(xué)科的) team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”

1.By “a one-way street” (Line 1, Para. 1), the author means ________.

A. university researchers know little about the commercial world

B. there is little exchange between industry and academia

C. few industrial scientists would quit to work in a university

D. few university professors are willing to do industrial research

2.The word “deterrent” (Line 3, Para. 1) most probably refers to something that ________.

A. keeps someone from taking action

B. helps to move the traffic

C. attracts people’s attention

D. brings someone a financial burden

3.What was Helen Lee’s major consideration when she changed her job in the middle of her career?

A. Flexible work hours.

B. Her research interests.

C. Her preference for the lifestyle on campus.

D. Prospects of academic accomplishments.

4.Guy Grant chose to work as a researcher at Cambridge in order to ________.

A.do financially more rewarding work

B.raise his status in the academic world

C.enrich his experience in medical research

D.take advantage of better intellectual opportunities

5.What contribution can industrial scientists make when they come to teach in a university?

A.Increase its graduates’ competitiveness in the job market

B.Develop its students’ potential in research.

C.Help it to obtain financial support from industry.

D.Adapt its research to practical applications.
