A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.

Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.

Some people go even further. They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of  hopelessness and discourages them from making efforts to build a safer world.

In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.

Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

What can we conclude from the recent study?

A. People think highly of science.

B. People hold mixed opinions about science.

C. Science is getting dangerously out of control.

D. Science is used for both good and bad purposes.

A. The development of science will hopelessly slow down.

B. Businesses will have even greater influence on science.

D. People will work more actively to put science under control.

The discussion should reach beyond scientific societies because __________.

A. scientists have failed to predict the outcomes

B. the ties between different areas need strengthening

C. united efforts are necessary for the development of science

D. people need to work together to prevent the bad use of science

What is the main idea of the passage?

A. Science and its applications bring us many dangers.

B. The development of science mostly lies in people’s attitudes.

C. Mankind can largely take control of science with their efforts.

D. The future of science will be influenced by the dangerous ideas.

Passage Fifteen (Contribution of Coeducation)

Imagining being asked to spend twelve or so years of your life in a society which consisted only of members of own sex. How would you react? Unless there was something definitely wrong with you, you wouldn’t be too happy about it, to say the least. It is all the more surprising therefore that so many parents in the world choose to impose such abnormal conditions on their children – conditions which they themselves wouldn’t put up with for one minute!

Any discussion of this topic is bound to question the aims of education. Stuffing children’s heads full of knowledge is far from being foremost among them. One of the chief aims of educations is to equip future citizens with all they require to take their place in adult society. Now adult society is made up of men and women, so how can a segregated school possibly offer the right sort of preparation for it? Anyone entering adult society after years of segregation can only be in for a shock.

A co-educational school offers children nothing less than a true version of society in miniature. Boys and girls are given the opportunity to get to know each other, to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms of academic ability, athletic achievement and many of the extra-curricular activities which are part of school life. What a practical advantage it is ( to give just a small example ) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense co-education makes of the argument that boys are cleverer than girl or vice-versa. When segregated, boys and girls are made to feel that they are a race apart. Rivalry between the sexes is fostered. In a coeducational school, everything falls into its proper place.

But perhaps the greatest contribution of co-education is the healthy attitude to life it encourages. Boys don’t grow up believing that women are mysterious creatures – airy goddesses, more like book-illustrations to a fairy-tale, than human beings. Girls don’t grow up imagining that men are romantic heroes. Years of living together at school dispel illusions of this kind. There are no goddesses with freckles, pigtails, piercing voices and inky fingers. There are no romantic heroes with knobbly knees, dirty fingernails and unkempt hair. The awkward stage of adolescence brings into sharp focus some of the physical and emotional problems involved in growing up. These can better be overcome in a co-educational environment. Segregated schools sometimes provide the right conditions for sexual deviation. This is hardly possible under a co-educational system. When the time comes for the pupils to leave school, they are fully prepared to enter society as well-adjusted adults. They have already had years of experience in coping with many of the problems that face men and women.

Directions: For each blank in the following passage there are four words or phrases marked A,B,C and D. Fill in each blank with a word or phrase that best fits the context.

Being alone in outer space can be   36  . That is one reason why astronauts on solo(单独的) space flights were given plenty of work to keep them   37  . They were also in constant communication with people on the earth.   38  , being with people from whom you cannot get away might be even harder than being alone. This is what happens on long submarine(潜水艇) voyages. It will also happen on  39  space flights in the future. Will there be special problems of adjustment under such conditions?

Scientists have studied the reactions of men to one another during long submarine voyages. They have also found that the longer the voyage lasts, the more serious the problem of  40  is. When men are  41  together for a long period, they begin to feel   42   . Everyone has little habits of speaking and behaving that are ordinarily acceptable. In the limited space over a long period of time, however, these little habits may become very   43  .

Apparently, although no one wants to be  44  all the time, everyone needs some degree of privacy. When people are enclosed together, they are in what is called stress situation. That means that they are under an unusual amount of  45  or stress.

People who are well-adjusted are able to   46  stress situations better than others. That is one reason why so much care is taken in   47  our astronauts. These men undergo a long period of testing and training. One of the things tested is their behavior under stress, and thus they can do better than ordinary people.

     Australia’s Great Barrier Reef will lose most of its coral cover by 2050 and, at worst, the world’s largest coral system could collapse by 2100 because of global warming, a study recently said.

     The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”

     The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.

     Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower  temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.

     The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.
