Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.
1. Which of the following is true according to the passage?
A. Genetic limitation will be beneficial for some women
B. A large number of genes will prevent us from developing
C. Prohibition(禁止) of cloning might limit the freedom of scientists
D. First cloned humans might be normal according to scientists

Since we couldn’t dive, we stayed on our boat that was meant to keep track of us when we were diving. 3. We dived quickly down in depth into a warm and colourful place. Meanwhile, the boat was following us all the way.
There were various sea creatures swimming around us. Interestingly, I was joined by a turtle which stayed on ray mask for a while. And it followed me during the rest period of my dive. 4. I was amazed and even shocked! Beautiful living coral covered nearly 100 percent of the bottom! Besides the turtle, many more sea animals passed by me closely. It was so fun. All stress, noise and troubles of life were left at the surface of the sea.
5. I dived for as long as I could that day. This was how I felt about Abralda—I loved it and never wanted to leave. In fact, we are already planning another diving research in Abralda.
A. It made us disappointed and upset.

There are many thoughts on the origins of civilization. One of the major factors involved was the increase in population. The development of techniques, primarily irrigation and flood control, which permitted agriculture in special areas such as the flood plain of the Tigris and Euphrates rivers, made possible the support of large population. Once populations reach a certain number, the older pattern of social organization breaks down and new ones develop. Specifically the older system, whereby each individual participated in food production and maintained a similar standard of living and whereby kinship(家属关系) served as the basic method of social organization, was replaced by the occupational division of labor, political and religious hierarchies(等级制度), public works such as road and public building construction, class systems, codes of law, markets, new forms of warfare, and urban centres. Allied with these important sociological traits are material traits, such as monumental architecture and the development of science and, in many cases, metallurgy(冶金学) and writing systems.
The earliest civilization, Sumer, developed in the Middle East. This was the Bronze Age of the Old World, during which people first developed the art of metallurgy, civilization also arose in other parts of the Old World, first in Egypt, China, and India, and later in Europe and Africa. At this time, civilization also developed independently in the New World, in the Mexican area and in Peru and its adjacent(邻近的) areas.
In the Old World the Bronze Age was followed by the Iron Age, which saw the rise and fall of great empires and the shift of power from the Middle East to Greece and Rome and then to Western Europe. In the 1700s the Industrial Age began, leading directly to the modern civilization of today.
46. The author of this passage __________________________________.
A. gives a comparison between ancient civilization and modern civilization
B. suggests that population increase is most important in the development of civilization
C. tries to explain how civilization developed in human history
D. explore the relation between agriculture and industry
47. According to the first paragraph, the increase in population __________________.
A. resulted in the development of agricultural technology
B. resulted from the breakdown of old social organization
C. caused the occupational division of labor
D. was impossible without the development of agriculture
48. The word “traits” in Paragraph One most likely means ____________________.
A. main appearances B. great achievements
C. distinguishing features D. outstanding successes
49. Which of the following is NOT true according to the passage?
A. The Bronze Age is one of the earliest civilizations.
B. The Industrial Age started in the Middle East.
C. The Bronze Age developed into the Iron Age.
D. The use of metal instruments started from the Bronze Age.
50. Which of the following is NOT included in the expression “the Old World” used in the passage?
A. American continent. B. Both Western and Eastern Europe.
C. African continent. D. Asian countries.

Scientific discoveries have changed man's life a great deal during the past century. First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication, the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored.
Scientific discoveries have also changed man's moral atmosphere. Ethical (伦理的) issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation had come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.

高二英语阅读理解简单题查看答案及解析
The story of chocolate begins with the discovery of America in 1492. Columbus was the first European to come into contact with cacao. Columbus was struck by how much value the Indians placed on them as he did not know the beans were used by currency. It is unlikely that Columbus brought any of these beans back to Spain and it was not until about 25 years later that Cortez grasped the commercial possibilities when he found the Aztecs using the beans to make the royal drink “chocolatl”.
The Spanish, in general, were not fond of the bitter drink so Cortez and his followers made it more palatable by adding sugar and later cinnamon(肉桂) and vanilla(香草) were added. Spanish monks( 僧侣) let the secret out back home and, although the Spanish hid it from their neighbors for a hundred years, finally chocolate’s popularity grew until it was their fashionable drink at the French court(宫廷) and the wise choice of customers at London meeting houses.
The cacao tree is strictly a tropical plant only in hot, rainy climates. Thus, its cultivation (培育 ) is limited to countries not more than 20 degrees north or south of the equator ( 赤 道 ). The cacao tree is very delicate and sensitive. It needs protection from the wind and requires a fair amount of shade under most conditions. This is true especially in its first two or three years of growth. A newly planted young cacao tree is often sheltered by a different type of trees. It is normal to plant food crops for shade such as bananas, or coconuts. Rubber trees( 橡胶树) and forest trees are also used for shade. Once established, however, cacao trees can grow in full sunlight, provided there are fertile soil conditions and intensive farming. With cutting and careful cultivation, the trees of strains will begin bearing fruit in the fifth year. With extreme care, some strains can be stimulated to produce good crops in the third and fourth year.
The process of turning cacao into chocolate hasn’t changed much since the late 1800s, when the Swiss learned to make fine unsweetened chocolate. Mixed with cocoa butter and other ingredients and then “purified”, the finished result is shaped, cooled, packaged by machine, distributed, sold and of course, eaten!
1.Why didn’t Columbus bring beans back to Spain at once when he found cacao?
A.Because he couldn’t afford to buy the cacao bean.
B.Because he didn’t know how to turn cacao bean into chocolate.
C.Because he was not aware of the commercial value of cacao bean then.
D.Because Spaniards then didn’t favour the chocolate that the Aztecs originally drank.
2.The underlined word “palatable” in paragraph 2 probably means _______.
A.affordable B.agreeable
C.patent D.portable
3.Which of the following is correct about cacao tree?
A.Cacao trees require hot, rainy climates and adequate sunlight.
B.Cacao trees need a lot of looking after to be used commercially.
C.Cacao trees won’t produce fruit until the fifth year.
D.Cacao trees can grow well in all continents.

In William Shakespeare’s play, Julius Caesar, there is major difference between two of the characters, Brutus and Mark Antony, Brutus was very honorable and Antony was very persuasive. When Brutus spoke at Caesar’s funeral, he appealed to the people’s logic and Antony spoke to the emotions of the people. Antony was very smart and used his brain frequently during the play and Brutus was very naive(天真的,率直的) about many of things.
Brutus was very honorable in the way that he always told people the truth. Antony was persuasive in the way that he used people to get whatever he wanted. For example, Antony used Lepidus to seek revenge on all of the conspirators (同谋者,阴谋者) to take the blame for their deaths. Brutus’ speech at Caesar’s funeral was very short and to the point and spoke to the logic of the people in the crowd. For example, Brutus spoke in a detached way about Caesar’s death while Antony spoke to the emotions of the crowd by crying and talking about all the good things that Caesar did for Rome. Antony’s intelligence was very apparent throughout the play and Brutus appeared to be naive about many things. Antony as smart in the way that he controlled people to his own advantage. Brutus appeared to be naive throughout the whole play because he believed everyone was as honorable as he. Brutus did not question what he was told, assuming it was always true.
In conclusion, in William Shakespeare’s play, Julius Caesar, there is a major difference between the two characters, Brutus and Mark Antony. The strongest contrast between the two characters appears to be their ability and inability to be both honorable and persuasive.
