单选题 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."

单选题I don"t doubt ______ the stock market will recover from the economic crisis.

单选题 (D) "Time cannot be added to a person's life, but it can be made more valuable by avoiding waste. " This was the philosophy of a man who devoted most of his time to the creation of new plants: Luther Burbank, the plant magician. Burbank has been called the plant magician because he could do things with plants which were as amazing as the tricks of a magician. He truly astonished the world with his achievements in the development of many kinds of plants, such as giant fruits with new flavors and trees which grew faster than their ancestors. These, and many more achievements, were of great economic value and benefit to people all over the world. In his lifetime of seventy-seven years Burbank became an American legend. He began life in 1849 on a farm in the state of Massachusetts. It was the same year that men across the continent in California discovered gold, that precious metal so eagerly sought after in the earth. Eventually Burbank would follow them. But he would spend his life drawing a different treasure from the same California earth: a wealth of new plants and fruits. The Massachusetts countryside may have provided young Burbank with a feeling for the mysteries of nature, but his scientific training came during the visits of an uncle who was a scientist. Through his uncle, Luther met the famous naturalist, Louis Agassiz. Agassiz introduced him to the complicated process by which plants grow, such as the steps in the making of seeds from pollen (花粉) carried by insects, by birds, by the very winds of the field. Attracted by the ways of nature, Burbank took his first steps into the work that was to occupy his whole life.
