Passage 1When cars first started appearing on the streets of the world：few people took them seriously.They were toys play things for grown men who didn t have much to do.No one thought that the automobile would ever become the world s most popular form of transportation There seems never to have been a civilization without toys：but when and how they developed is unknown.They probably ame about just to give children something to do In the ancient world：as is today：most boys played with some kinds of toys and most girls with another.In societies where social roles are rigidly determined：boys pattern their play after the activities of their fathers and girls after the tasks of their mothers.This is true because boys and girls are being prepared：even in play：to step into the roles and responsibilities of the adult worldWhat is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same.The changes have been mostly in terms of craftsmanship，mechanics，and technology.It is the amazing.In Egypt，the Americas，China，Japan and among the Arcth e world and their persistence to the present that i universality of toys with regard to their development in all parts of th ag）peoples，generally the same kinds of toys appeared.Variations depended on local customs and ways of life because toys imitate their surroundings.Nearly every civilization had dolls，little weapons，toy soldiers，tiny animals and vehicles ecause toys can be generally regarded as a kind of art form，they have not been subject to technological leaps that characterize inventions for adult use.The progress from the wheel to the oxcart to the automobile is a direct line of ascent （进步）.The progress from a rattle（拨浪鼓）used by a baby in3000 BC to one used by an infant today，however；is not characterized by inventiveness.Each rattle is the product of the artistic tastes of the times and subject to the limitations of available material6.The reason why the toys most boys play with are different from those that girls play with is that A.their social roles are rigidly determined B.most boys would like to follow their fathers'professions C.boys like to play with their fathers while girls with their mothers D.most girls would like to follow their mothers professions7.One aspect of"the universality of toys"lies in the fact that A technological advances have greatly improved the durability of toys B the improvement ofcraftsmanship in making toys depends on the efforts of universities C the exploration of the universe had led to the creation of new kinds of toys D.the basic characteristics of toys are the same the world over9.Which of the following is the author s view on the historical development of toys？A.The craftsmanship in toy-making has remained essentially unchanged B Toys have remained basically the same all through the centuries C The toy industry has witnessed great leaps in technology in recent years D Toys are playing an increasingly important role in shaping a child s character.9.Regarded as a kind of art form，toys A.follow a direct line of ascent B also appeal greatly to adults C are not characterized by technological progress D reflect the pace of social progress10.The author uses the example of rattle to show that A in toy-making there is a continuity in the sue of materials B.even the simplest toys can reflect the progress of technology C.it often takes a long time to introduce new technology into toy-making D.even a simple toy can mirror the artistic tastes of the timeSpace is a dangerous place, not only because of meteors (its) but also because of rays from the sun and other stars.The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food, which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage Radiation is the greatest known danger to explorers in space. The unit of radiation is called rem". Scientists have reason to think that a man can put up with far more radiation than 0. 1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (aa B5) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys; the apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on whenthey spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so11. According to the first paragraph, the atmosphere is essential to man in that A. it protects him against the harmful I B. it provides sufficient light for plant growth C. it supplies the heat necessary for human survival D it screens off the falling mete12. We know from the passage that A. exposure to even tiny amounts of radiation is fatal B. the effect of exposure to radiation is slow in coming C radiation is avoidable in space exploration D astronauts in spacesuits needn t worry about radiation damage13. The harm radiation has done to the apollo crew members A is insignificant B seems overestimated C is enormous D remains unknown14. It can be inferred from the passage that A. the Apollo mission was very successful B protection from space radiation is no easy job C astronauts will have deformed children or grandchildren D radiation is not a threat to well-protected space explorers15.The best title for this passage would be A Astronauts in the Outer SpaceB.Research on radiationC.Effects of Space Radiation D Importance Protection against Radiation第三部分：词汇与结构（共5小题；每小题4分，满分20分）此部分共有5个未完成的句子，针对每个句子中未完成的部分有4个选项，请从A、B、C、D四个选项中，选出可以填入空白处的最佳Without water from the Nile river，egypt a farming country and become a desert.QA will cease to be B would cease to beaC will cease being D would cease being17.Although he refused to act on my suggestion，he had to admit that what I said.IA.it was something in ere was some nething asIC.it was something as D.there was something in18.There is little farming in that area and all you can see is miles of wild countryside.DA.if so B if such C if not D if any9.In his lecture，the education expert emphasized the fact that nowadays children are exposed to many influences that of their families.IA.rather than B.other than C.except for D.but for The singer on the stage has a young face and a voice of an DA boy..angel B boy sangelIc D boy第四部分：写作（满分20分根据下面所给的题目和要求用英语写出一篇不少于80词的短文。
