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 (学术界) are more important than 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 in the middle of her career was to take advantage of the greater freedom to choose research questions.

　　The effect of a salary cut is probably less serious 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 (制药的) company before returning to university as a post-doctoral(博士后的) 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 (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to manage budgets and negotiate contracts. They are also well placed to bring something extra to their teaching 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 ______.

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

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

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

【小题1】By “a one-way street” (Line 1, Para. 1), the author means ______.

Quality after-school programs are designed to improve academic performance, decrease youth crimes and other high-risk behaviors, and help young people grow into healthy, successful adults.

　 The effect of quality after-school programs on academic performance is clear. Studies show that students who take part in such programs show better work habits, higher rates of homework completion, improved grades, and higher scores on achievement tests. They also have fewer absences and are less likely to blame. After-school programs also influence high-risk teen behavior. Various studies show decreased rates of crime, drug use, and teen sex among youth who join in well-run after-school programs when compared to similar youth who do not. Finally, after-school programs play an important role in supporting the following fields of development: physical development, mental development and social development. Thus, one can safely say that after-school programming is an effective method to help young people become contributing members of society.

Although there is enough proof from both small and large assessments that after-school programs can make a positive difference, it is important to note that not all programs are equal. First, dosage (时量) matters ---- young people who attend the most hours over the most years benefit more than members who attend less often or over a shorter period of time. Next, after-school programs make bigger difference for those students who need help most and have the fewest choices. Finally, program qualities matter. After-school programs work best when they create unique opportunities for youth. They should provide opportunities for positive relationships, skill building, meaningful involvement (参与), expression, suggestion, service, and work. Staff characteristics make an important difference in the quality of a program. The adults should treat youth as partners, create safe and fair environments, encourage personalized (个性化的) involvement, and actively create learning opportunities. In short, although after-school programs have promising future, how they are designed and run matters.
