阅读下列短文，然后从各题所给的A、B、C、D四个选项中，选出最佳选项。

　　The plan：turn Mars into a blue world with streams and green fields, and then fill it with creatures from the earth．

　　This idea may sound like something from a science fiction, but it is actually being taken seriously by many researchers．

　　This suggests the future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA this week．Leading researchers as well as science fiction writers will attend the event．It comes as NASA(美国宇航局)is preparing a multi-billion-dollar Mars research program．

　　“Turning Mars into a little earth has long been a topic in science fiction,” said Dr．Michael Meyer, NASA's senior scientist．“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 from 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 the 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, 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 life forms, all the strange microbes that we hope to find buried in the soil,” said Dr．Pratt．

　　Monica Grady, a planetary scientist at the Natural History Museum, London, shares this view．“We cannot risk starting a global experiment that would wipe out the precious information we are looking for,” she said．“This is just wrong”．

The number of speakers of English in Shakespeare’s time is estimated(估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.

In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.

The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West.

A. The Difficulties of Learning English

The finest and most sought-after violins were handcrafted by an Italian violin maker over 250 years ago. The man’s name was Antonius Stradivarius. He was born in 1644 and began his career 21 a violin maker’s apprentice (学徒). Working on his own by 1680, he became determined to make 22 that could reproduce tones as rich as those produced by the human voice. He 23 several shapes and styles for his violins until he arrived at a design that pleased him. During his career he crafted 1,100 violins. Those in 24 have become treasured possessions.

When you take a walk in any city, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reason why people keep a dog has changed. In the old days people used to train dogs to protect(保护) themselves against attacks by other beasts. Later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission.
These days people in the city need not protect themselves against attacks from animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery（抢劫）. But the most important reason is for companionship. For a child, a dog is a best friend when there are no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their natural children have grown up. So the main reason why people keep dogs has changed from protection to friendship.
