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) 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 prospects 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 (制药的) 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 (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary 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.”

　　Radioactivity is dangerous. It may cause skin burns, it may destroy good tissues（组织）and it may cause illness that could be passed on to our children and. grand children. In case of exposure（暴露）it may even cause death.

　　In the early days of radioactivity, scientists did not realize these dangers. Marie and Pierre Curie, after having worked for a while with radioactive materials, noticed that their fingers were reddened and swollen（红肿）and the skin was peeling off. Henry Becquerel carried a small tube with radium in it in his waistcoat pocket, and was surprised to find a bum on his chest. Other early workers also reported bums and harm of different kinds.

　　The strange fact is that it can harm without causing pain, which is the warning signal we expect from harmfulness. Pain makes us pull back our hands from a fire or a hot object, but a per-son carrying radioactive materials has no way of telling whether he is touching something too“hot” for safety. Besides, the“burns” or other harmfulness that radioactivity produces may not appear for weeks. A person may have been hurt without knowing it for some time.

(1) Which is the topic sentence for this passage?

[　　]

A．Radioactivity may ever cause death.

B．Radioactivity does great harm to children.

C．Radioactivity may do harm to people without being known.

D．Radioactivity is dangerous.

(2) A few people were mentioned in the passage. They ________.

[　　]

A．were all famous scientists of great achievements

B．died of radioactivity

C．knew little about radioactivity

D．did experiments on themselves to find the danger of radioactivity

(3) According to the point of the passage, pain ________.

[　　]

(4) The sentence in the fifth line of the second paragraph“the skin was peeling off”means“________”．
