The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.

　　This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multi?billion?dollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物学). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”

  Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.

　　But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.

  In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.

　　But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said， “This is just wrong.”

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough，the answer to both these questions is yes．To some extent our intelligence is given to us at birth，and no amount of special education can make a genius out of a child born with low intelligence．On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings．Thus the limits of a person’s intelligence are fixed at birth，but whether or not he reaches those limits will depend on his environment. This view, now held by most experts can be supported in a number of ways．

       It is easy to say that intelligence is to some extent something we are born with．The closer the blood relationship between two people, the closer they are likely to be in intelligence．Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different．If on the other hand we take two identical twins, they will very likely be as intelligent as each other．Relations like brothers and sisters，parents and children，usually have similar intelligence, and this clearly suggests that intelligence depends on birth．

       Imagine that now we take two identical twins and put them in different environments．We might send one, for example, to a university and the other to a factory where the work is boring．We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part．This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence．

By using the example that two people closer in blood relationship are closer in intelligence that writer wants to prove _________．

       A．intelligence is given at birth

       B．intelligence can be developed by environment

       C．intelligence can be developed by experience

       D．education plays an important part in the development of education

A child who lives in rich and varied surroundings turns out higher in intelligence because ________．

       A．his family is rich and therefore can afford to develop his intelligence

       B．he can break the limits of intelligence fixed at birth

       C．his family is rich and provides him with various healthy food

       D．these surroundings are likely to help him reach the limits of their intelligence

Writer of this article believes that _________．

       A．the development of one’s intelligence is determined by many factors working together

       B．environment plays the most important role in the development of intelligence

       C．education plays the most important role in the development of intelligence

       D．birth plays the most important role in the development of intelligence

The best title for this passage might be __________．

       A．Intelligence                  B．Birth and Environment

       C．The Answer to a Question       D．Intelligence and Education

Are some people born clever，and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence.

Thus the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligent. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely to be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.

There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved (演化) from ceremony. The argument for this view goes as follows.

       In the beginning, human beings viewed the natural forces of the world -even the seasonal changes - as unpredictable, and they sought through various means to control these unknown and feared powers. Those measures which appeared to bring the desired results were then kept and repeated until they hardened into fixed ceremonies. Eventually stories arose which explained the mysteries of the ceremonies. As time passed some ceremonies were abandoned, but the stories, later called myths, remained and provided material for art and drama.

       Those who believe that drama evolved out of ceremony also argue that those ceremonies contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site had to be provided for performances and when the entire community did not participate, a clear division was usually made between the "acting area" and the "auditorium " . In addition, there were performers, and, since considerable importance was attached to avoiding mistakes in the performing of ceremonies, religious leaders usually took that task.. Wearing masks and costumes, they often acted other people, animals, or supernatural beings, and imitated the desired effect -- success in hunt or battle, the coming rain, etc. as an actor might. Eventually such dramatic representations were separated from religious activities.

      Another theory traces(追溯) the theater's origin from the human interest in storytelling. According to this view, tales (about the hunt, war, etc) are gradually developed, at first through the use of action and dialogue, and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitations of animal movements and sounds.
