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.”

2.The underlined word “deterrent” most probably refers to something that ________.

阅读下列短文，从每题所给的四个选项中选出最佳选项。

　　There are 25,000 kinds of bees identified in the world. The most well-known are the honey bee. In the United States there are known 3,500 species. Most bees do not live in large groups, they are solitary(独居的)bees. The honey bee is not a native of the United States. The first bees were brought to the U.S. from Holland. Later other bees were brought from many other countries. South America had some honey bees, but they did not produce much honey.

　　When honey bees were brought to the United States, native American called them“white man's flies”. Soon bees became a known sight in America.

　　In Brazil, honey bees did not survive well and scientists brought African bees to Brazil. These bees were found to be aggressive(好斗的) and mistakenly escaped into the wild. These bees are very common in Brazil now.

　　Beekeepers raise bees for honey, but more often they raise them to pollinate crops. Pollination occurs when the bee lands on a flower and some of the pollen(花粉)gets stuck to the bees' hairy legs. The next time the bee lands, some of the pollen falls off her legs and onto another flower, allowing it to reproduce.

　　Beekeepers have been raising bees for their honey for thousands of years. The first beekeepers kept their bees in hollow logs or clay pots. Now they keep the bees in wooden hives. When beekeepers raise bees for honey, they must remove part of the hive to retrieve (获取) the honey. They must“calm”the bees by using a special smoker. The smoke is puffed out around the bees and the bees move slower and are not as aggressive.

1．What's the best title for the passage?

[　　]

A．An Introduction to Bees.　　　　　　B．Why Bees Are Kept.

C．The Great Use of Bees.　　　　　　D．Bees in the USA.

2．What's the meaning of the underlined word“pollinate”?

[　　]

A．Make something fertile (结果实的) with pollen.

B．Get pollen away from.

C．Plant.

D．Harm.

3．From the passage we can infer that _____.

[　　]

A．bees want their honey to he taken away in order to get more room

B．all bees are kept by raisers

C．bees don't want their honey to be taken away

D．it is easy to retrieve the honey

　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.

　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.

　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.

　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.

　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?

　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.

　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.

　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.

　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.

　　　A.mean a warming - up im the Arctic

　　　B.raise the temperature of the earth's surface

　　　C.prevent the sun's rays from reaching the earth's surface

　　　D.account for great changes in the climate in the northern hemiphere

　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.

　　　A.mainly because the levels of carbon dioxide are rising

　　　B.partly due to variations in the output of solar energy

　　　C.possibly because the ice caps in the poles are melting

　　　D.exclusively due to the effect of the inertia of the earth's climate

　　70.On the basis of their models,scientists are of the opinion that ________.

　　　A.the climate of the world should be becoming cooler

　　　B.the new Ice Age will be delayed by the greenhouse effect

　　　C.the man - made warming effect helps to increase the solar effects

　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

D
