Louis Pasteur, the famous French chemist and bacteriologist(微生物学家), invented “pasteurization”. In 1854 Pasteur was made head of the department of science at the University of Lille, and it was there that he made one of his most famous discoveries. Lille was a major center for wine and beer-making, and some of the local wine-makers asked Pasteur if he could help solve the problem of keeping wine fresh. At that time, it was believed that food and drinks go “bad” due to a purely chemical process. But during a series of experiments Pasteur proved that tiny living organisms(微生物)caused food and drinks to go bad. In the case of wine and beer the organisms are already present in the form of the various yeasts (酵母) that caused the fermentation(发酵) process. Pasteur discovered that heating the wine gently for a few minutes after it had fermented would kill off the yeast that was left in the wine, with the result that the wine would remain fresh for much longer. He also proved that food and drinks could be turned bad by other organisms that were present in the air, and that they too would keep fresh much longer if they were kept in airtight containers.
The heating process was so successful that it made Pasteur famous. It was named “pasteurization” in his honour, and by about 1900 it had been widely used for processing and bottling cows’ milk. The result was a huge drop in the number of bottle-fed babies dying from infant diarrhea(婴儿腹泻)and from that time on it has been a standard treatment for milk and many other food products. This simple process has saved thousands, possibly millions, of lives worldwide.
1.Pasteur became ___________ in 1854.
A. the chairperson of the science department at the University of Lille
B. the director of a chemical laboratory at the University of Lille
C. the general manager of a large beer-making company
D. the president of the University of Lille
2.According to the passage, Lille was a major center for ___________ in the mid-19th century.
A. growing grain crops B. making beer and wine
C. doing chemical research D. producing various kinds of yeasts
3.In the last sentence of Paragraph 1, the underlined word “they” refers to ___________.
A. wine and beer B. food and drinks C. the various yeasts D. other organisms
4.We can infer from the passage that Pasteur’s discovery __________.
A. is no longer widely used for treating milk and other food products
B. did not bring much profit to the wine makers in Lille
C. has done a lot of good to children in the world
D. has greatly reduced the number of wars in the world
5.According to the passage, we know it is that causes food and drinks to go bad.
A. a purely chemical process. B. tiny living organisms(微生物)
C. keeping them in airtight containers. D. the heating process

The Great Wall of China, one of the greatest wonders of the world, was enlisted in the World Heritage by the UNESCO in 1987. Just like a gigantic dragon, the Great Wall winds up and down across deserts, grasslands and mountains, stretching about 6,700 kilometers from east to west of China. With a history of more than 2,000 years, some parts of the Great Wall are now in ruins or even entirely disappeared. However, it is still one of the most appealing attractions around the world.
No one can tell for sure when the building of the Great Wall was started, but it is popularly believed that it originated as a military fortification(要塞) against intrusion by tribes on the borders during the earlier Zhou Dynasty. Late in the Spring and Autumn Period, some states extended the defence work to prevent the attacks from other states.
It was not until the Qin Dynasty that the separate walls were connected to form a defensive system by Emperor Qin Shi Huang. After the emperor unified the country in 214 BC, he ordered the construction of the wall. It took about ten years to finish and the wall stretched from Gansu Province to Jilin Province. The wall not only served as a defence in the north but also symbolized the power of the emperor.
Further construction also experienced several dynasties. The present Great Wall in Beijing is mainly remains from the Ming Dynasty. Today, the Great Wall has become a must-see for every visitor to China. Few can help saying “Wow” when they stand on top of a beacon tower and look at this giant dragon. It has become a national pride of Chinese people.
1.The underlined word “appealing” probably means “______”.
A. huge B. attractive
C. ordinary D. moving
2.In the Qin Dynasty, ______.
A. the construction of the Great Wall was finished in 204 BC
B. the emperor wanted to invade other minor states
C. the defensive system of the Great Wall was separated
D. the Great Wall began its way from Jilin Province
3.According to the passage, the Great Wall _______.
A. is from the west to the east B. is as long as 6,700 miles
C. was built in several dynasties D. was begun in the Qin Dynasties
4.The best title for the passage probably is _______.
A. History of the Great Wall B. Culture of the Great Wall
C. Construction of the Great Wall D. Projection of the Great Wall

The scientific world continues to be amazed by the speed of the development of cloning. Some scientists now suggest that the cloning of humans could occur in the near future. Despite the benefits of cloning, however, certain ethical (道德的) questions concerning the possible abuse (滥用) of cloning have been raised. At the heart of these questions is the idea of humans influencing life in a way that could harm society, either morally or in a real physical sense. Some people object to cloning because it allows scientists to "act like God" in the handling of living organisms.
The cloning of Dolly raised the debate over this practice to a whole new level. It has become obvious that the technology for cloning Dolly could also be used to clone humans. A person could choose to make two or ten or a hundred copies of himself or herself by the same techniques used with Dolly. An active debate about the morality of cloning humans arises. Some people see benefits from the practice, such as providing a way for parents to produce a new child to replace one dying of a fatal disease. Other people worry about humans taking into their own hands the future of the human race.
At the beginning of the twenty-first century, many scientists say the controversy over the ethics of cloning humans is overstressed because of the unpredictability (不可预测性) of cloning in general. While scientists have cloned animals such as sheep, mice, cows, pigs, and goats, fewer than 3 percent of all those cloning efforts have succeeded. The animal clones that have been produced often have health problems. Scientists believe the rapid reprogramming in cloning can introduce random (任意的) errors into a clone’s DNA. Those errors have altered individual genes in minor ways, and the genetic defects (缺陷) have led to the development of major medical problems. Some scientists say this should make human cloning out of the question, but others argue that cloning humans may actually be easier and safer than cloning animals. Whatever, I agree that further research in the field of cloning is needed.
1.Some people are against cloning of humans because they think _________.
A.the practice takes too much time and money B.the cloning technology is still not mature C.humans control the future of the human race D.the population in the world will be too large
2.Some scientists think the debate over ethics of cloning humans is overstressed because ____.
A.cloning of human beings is completely impossible B.the result of cloning can’t be predicted in general C.cloning of animals is a failure D.there are big errors in a clone’s DNA
3.We can learn from the text that _______.
A.cloning of humans is a very controversial issue B.the cloning of Dolly begins to raise the debate over cloning of humans C.there are medical problems in cloning animals D.cloning humans is easier and safer than cloning animals
4.The text is mainly about _______.
A.the benefits of cloning B.the ethics of cloning C.the history of cloning D.the defects of cloning
