ten deaths around the world．Those who survived the disease were left with ugly scars on their sjun．
It had long been well known among farmers that people who worked with cows seldom caught smallpox；instead，they often caught a similar but much milder disease called cowpox (牛痘) ．A Bridsh doctor called Jenner was extremely interested in this，and so he studied cowpox He believed that，by vaccinating (给接种疫苗) people with the disease，he could protect them against the much worse disease smallpox．In 1796，he vaccinated a boy with cowpox and，two months later，with smallpox．The boy did not get smallpox．In the next two years，Jenner vaccinated several children in the same way，and none of them got the disease．
News of the success of Jenner’s work soon spread．Vaccination soon became a common method to protect people against other diseases caused by virus，such as rable (狂犬病)，and vaccines (疫苗) were sent across the world to the United States and India．
It took nearly two centuries to achieve Jenner’s dream of getting free of smallpox from the whole world．In 1967，the world Health Organization (WHO) started a great vaccination program，and the last known case of smallpox was recorded in Somalia in 1977．The story of vaccinations does not end there，however．There are many other diseases that kill more and more people every year．Besides，many new diseases are being discovered．The challenge for medical researchers will，therefore，probably continue for several more centuries

A
Mathematical ability and musical ability may not seem on the surface to be connected, but people who have researched the subject -- and studied the brain—say that they are. Three quarters of the bright but speech-delayed children in the group I studied had a close relative who was an engineer, mathematician or scientist, and four fifths had a close relative who played a musical instrument. The children themselves usually took readily to math and other analytical subjects and to music.
Black, white and Asian children in this group show the same patterns. However, it is clear that blacks have been greatly overrepresented in the development of American popular music and greatly underrepresented in such fields as mathematics, science and engineering.
If the abilities required in analytical fields and in music are so closely related, how can there be this great discrepancy? One reason is that the development of mathematical and other such abilities requires years of formal schooling, while certain musical talents can be developed with little or no formal training, as has happened with a number of well-known black musicians.
It is precisely in those kinds of music where one can acquire great skill without formal training that blacks have excelled popular music rather than classical music, piano rather than violin, blues rather than opera. This is readily understandable, given that most blacks, for most of American history, have not had either the money or the leisure for long years of formal study in music.
Blacks have not merely held their own in American popular music. They have played a large role in the development of jazz, both traditional and modern. A long string of names comes to mind—W.C. Handy, Louis Armstrong, Charlie Parker…and so on.
None of this presupposes(假设，意味着) any special innate（先天的）ability of blacks in music. On the contrary, it is perfectly consistent with blacks having no more such inborn ability than anyone else, but being limited to being able to express such ability in narrower channels than others who have had the money, the time and the formal education to spread out over a wider range of music, as well as into mathematics, science and engineering.
36. what is the main idea of the first paragraph?
A. Mathematical ability and musical ability are connected.
B. Mathematical ability has more to do with the brain than musical ability.
C. More people are good at music than math.
D. More research should be done into the relationship between mathematical ability and math ability.
37. The word “discrepancy” (Para. 3) most probably means ____.
A. difference B. excellence C. inborn ability D. inability
(38. What can be inferred about opera?
A. It requires formal training.
B. It is often enjoyed by those with strong analytical ability.
C. It is disliked by blacks.
D. It is more difficult to learn than classical music.
39. Which of the following statements is true according to the last paragraph?
A. Blacks have special innate ability in music.
B. Unlike others, blacks do not have innate ability in music.
C. Jazz is one of the narrow channels through which blacks express their ability in music.
D. Those who have money and time choose mathematics over music.
40. which of the following questions does the passage mainly concern?
A. Are musical ability and mathematical ability connected?
B. Why have blacks been greatly over represented in the development of American popular misic?
C. What kinds of music require formal training?
D. What are the contributions made by black musicians?
People came to know that it was a sailing boat from Fuzhou in distant China. The boat
had sailed round the Cape of Good Hope(好望角), up the western coast of Africa, and finally to England. It had covered(航行) fifteen thousand miles — more than half of the distance round the world.Although it wa
s unexpected, the Chinese were warmly welcomed. The boat carried goods such as silk and tea as well as a number of gifts from the Emperor of China for the Queen of England.People had always mistakenly thought of the Chinese as a people not used to the sea. However, from centuries of trading and sailing in dangerous seas, the Chinese had learned how to build good boats and sail them well. The coming of this sailing boat to
London proved once again that the Chinese could sail to distant countries in the world.小题1: The Chinese sailing boat arrived in London .
| A．before she sailed to Africa | B．in the nineteenth century |
| C．hundreds of years ago | D．in the twentieth century |
| A．it was a small wooden boat | B．it carried Chinese silk an d tea |
| C．it had travelled fifteen thousand miles | D．it looked strange in several ways |
| A．The distance round the earth measures less than thirty thousand miles. |
| B．The Chinese Emperor gave silk and tea to the English Queen as gifts. |
| C．The Chinese boat came to London by accident. |

| D．surprised Londoners with an unusual boat |
At first, balls were made of grass or leaves(树叶) held together by vines(藤). Later they were made of pieces of animal skin sewed together and stuffed(塞满)with feathers or hay.
Even though the Egyptians were warlike, they found time for peaceful games. Before long they had developed a number of ball games, each with its own set of rules. Perhaps they played ball more for instruction than for fun. Ball playing was thought of mainly as a way to teach young men the speed and skill they would need for war.

| A．throwing stones often caused injuries | B．throwing stones was not fun |
| C．games with stones did not have rules | D．rocks were too heavy to throw |

| C．hides stuffed with hay or feathers | D．grass and leaves tied with vines |
| A．many different games with balls | B．many different kinds of games |
| C．only one ball game | D．different games with similar rules |

chaeologists from all over the world．At the site in the south-west suburb of Beijing, there is, for example, the earliest evidence of the use of fire by humans．It has also been proved that people lived there continuously between 500,000 and 10,000 years ago．Today, however, Zhoukoudian is in serious danger．Parts of the cave have been badly affected by rain and exposure to the air．Some areas are almost completely covered in weeds, causing serious damage．Pollution from nearby cement factories has also contributed to the problem．
The site is extremely expensive to maintain and it will cost between three and five million yuan to repair it．At the moment, visitors are not allowed to v
isit the caves．Zhoukoudian is on the World Cultural Heritage List, organized by UNESCO, the United Nations Educational, Scientific and Cultural Organization．The list is constantly checked．Any site which is seriously damaged or which is not properly protected is an endangered heritage, and UNESCO is very quick to do something about situations like this．They have recommended that the site be closed and repaired．If nothing is done to repair it, it could be removed from the list．
This is a very serious matter and the Chinese Academy of Sciences is trying to raise public awareness about it．They have suggested that the general public be encouraged to help with the problem．A professor at the Academy has proposed that a fund be established to raise money．
Dr Zhu Ming of the Academy said, “ We have requested that the government get involved, but we also need assistance from ordinary people．They can help by c
ontributing to the cost of repairing the caves．They are a precious part of our cultural heritage—it is of vital importance that we do something．If not, it will be a catastrophe．”小题1:Why is Zhoukoudian of great importance in China?

In the 19th century Americans from the eastern states moved out west to settle in the rich new lands along the Pacific coast. The most difficult part of their trip was crossing the “Great American Desert in the western part of the United States by horse and wagon.
The western desert can be very dangerous. There is little water and there are few trees. But the desert also has scenery of great beauty. Tall towers of red and yellow stone rise sharply from the flat sandy valley floor. The scene has been photographed many times and appears in movies and in TV.
In Arizona, man made dams across the Colorado River have made two large lakes in the middle of the dry desert country. At Lake Powell, the red stone arch of Rainbow Bridge rises high above the blue lake.
There are few roads. Many areas of Lake Powell’s shore can only be reached by boat or on foot. But hikers in this empty desert land sometimes find very old native American pictures, painted on the rocks.
In Death Valley, California, the summer temperature rises to 130 degrees. There is less than two inches of rain each year. Death Valley is the lowest place in America---- 925 meters below sea level. In the 1800s, many travelers died when they tried to cross this waterless valley in the terrible heat.
Although the desert is dry and seems empty, there is plenty of life if you look closely. Small insects, snakes and rats have learned how to live in the desert heat. They live under ground and come out at night, when it is cool. Plants such as cacti need very little water. When it does rain in the desert (sometimes only once or twice a year), plants grow quickly, and flowers open in a single day. For a short time, the desert is covered with brilliant colors.
小题1:In the 19th century, Americans moved from the east to the west because they ______.
| A．enjoy the trip | B．wanted to make their home there |
| C．wanted to find new grassland there | D．had no water to drink |
| A．the western desert is a good place for people to live in |
| B．there is little water but there are many trees in the desert |
| C．the desert is dangerous but it is full of life |
| D．till now, people know little about the desert |
| A．on foot | B．by boat | C．by car | D．by plane |
| A．illness | B．high temperature |
| C．cold weather | D．poisonous water |
| A．if they move about | B．if they cannot make holes underground |
| C．if they come out at night | D．if they drink much water |
