Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential(潜在的) resources to be found.Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin－offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even nonstick pans and mirrored sunglasses are byproducts(副产品) of technological developments in the space industry!
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.
1．Why does the author mention the questions in Paragraph 1?
A．To express his doubts.
B．To compare different ideas.
C．To introduce points for discussion.
D．To describe the conditions on Earth.
2．What is the reason for exploring space based on Paragraph 2?
A．Humans are nature－born to do so.
B．Humans have the tendency to fight.
C．Humans may find new sources of food.
D．Humans don’t like to stay in the same place.
3．The underlined word “spin－offs” in Paragraph 4 probably refers to ________.
A．survival chances B．potential resources
C．unexpected benefits D．physical possessions
4．What makes it possible for humans to live on other planets?
A．Our genetic makeup.
B．Resources on the earth.
C．The adaptive ability of humans.
D．Byproducts in space exploration.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
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.”
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. 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.
3. 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. exploit better intellectual opportunities
4. 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. Gear its research towards practical applications.
