Last evening I was watching the evening news on television. The news was about a prize for scientific discovery: I forgot what it was. The announcer, 1 name was Ralph story, reported something that caught my 2 . "All great discoveries," he said" are made by people between the ages of 20 and 30." 3 a little over 30 myself I wanted to disagree with him. Nobody wants to think that he is past the age of making any discovery. The next day I 4 to be in the public library and spent several hours looking up the 5 of famous people and their discoveries. Ralph was right.
First I looked at some of the scientific discoveries. One of the earliest discoveries, the famous experiment that proved that bodies of different weight fall 6 the same speed, was made by Galileo when he was 26. Madame Curie started her research that turned to a Nobel prize when she was 28.Einstein was 26 when he published his world-changing Theory of Relativity. Well, enough of that. Yet I 7 if those "best years" were true in other fields.
Then how about the field of 8 ? Surely it takes the wisdom of
age to make a good leader. Perhaps it does, but look when these people started their careers. Winston Churchill was elected to the House of Commons at the age of 26.Abraham Lincoln began the life of a country lawyer and was elected to the government at what age? Twenty -six.
But why dont best years come after thirty? After thirty,I 9 , most people do not want to take risks or try new ways. Then I thought of people like Shakespear and Picasso. The former was writing wonderful works at the ripe age of fifty, 10 the latter was enjoying trying new ways of painting when he was ninety! Perhaps there is still hope for me.

2.Questions 1 to 5 are based on the following passage.
The word health can be used in a number of ways. In the past , health is only the absence of disease or illness. Today, health has a broader meaning. Health is the state of your well-being that includes how you feel physically" target="_blank" title="ad.按照自然规律">physically, mentally, and socially. Wellness is another term that describes view of health. You can understand the need for a broader definition if you think about how health in your life is different from health in your grandparents' lives.
In1900, the main causes of death were diseases that were spread by bacteria（细菌）and viruses（病毒. If you had lived them, the danger of your dying from pneumonia（肺炎）would have been three times greater than the danger of your dying from cancer.
The diseases that were most common in 1900 affected people of all ages. It is not surprising, then that around 1900, the emphasis of health was on freedom from illness. Today many of the diseases that were common in 1900 can be prevented or cured by improved medicines and methods of sanitation（卫生）. Most diseases now are likely to occur later in life. You as a teenager will probably not have to think about the same threats to your health as your grandparents did.
These improvements in health conditions mean that not only can you now enjoy a better life, but you also have a greater chance of having a longer life. Controlling diseases has increased the life expectancy in the United States. Generally, people born more recently have higher life expectancies. Since1900, he life expectancy in the United States has increased by more than 27years. It has increased from 47 years for those born in 1900 to 74 years in 1981.
1.Accrding to Paragraph 1,health and wellness .

D. Pneumonia caused as many deaths in 1900 as cancer does today.
3 ."Life expectancy" in the last paragraph most probably means . 　　　
A. the kind of life that a person may expect to live.
B. the mode of life that a group of people have lived.
C. the length of time that a person or an animal has lived.
D. the length of time that people may expect to live.

Questions 1 to5 are based on the following passage.
Supernova are the most powerful an spectacularoutburst known in nature. What is called a Type II supernova is due to the collapse of a massive star, at least eight times as massive as the sun, that has used up its main nuclear fuel and produced a nickel-iron core. When this core can no longer support the pressure of the star's out layers, it collapses to form a neutron star of immensedensity. Over 2,500 million tons of neutron star material could be packed into a matchbox. Its temperature is around 100,000 million degrees centigrade. Numerous neutrons are produced in the collapsed star, which pass directly through the star into space, and this release of neutrons causes the core to respond with a chock wave that moves outward. When it meets the material that is falling inward, the result is a destructiveexplosion. Sometimes most of the star's material is blown away, leaving only a small, considerably dense remnant(剩余物) that may be a neutron star or, in extreme cases, a black hole.
A supernova is often more than 500 million times as bright as the sun. A supernova remnant may be detectable as a pulsar(脉冲星),an example of which is the Crab Nebula, known to be a remnant of the supernova observed in the year 1054.The 1987 supernova in the Large Cloud of Megallan had a low brightness by supernova standards, only about 250 million times that of the sun. At its brightest the supernova shone as a star between magnitudes(星的亮度等级)2 and 3,even though it was 170,000 light-year away.
1.What is the main topic of the passage?
A. The heat of supernovae.
B. The formation and power of a supernova.
C. The role of shock waves in a supernova.
D. The density of a neutron star.
2.According to the passage, which of the following is NOT true about the 1987 supernova?
A. It was located in the Large Cloud of Megallan.
B. It was 170,000 light-year away.
C. It shone as a star between magnitudes 3 and 4.
D. It had a low brightness.
3.The author of this passage is most likely___.
A.a biologist.
B.an economist.
C.a mathematician.
D. an astronomer.
4.What can be inferred from the passage about supernova?
A. They only happen to pulsars.
B. The sun is a remnant of a supernova.
C. They occur when two stars collide.
D. They sometimes result in a black hole.
5.According to the passage, what shows the beginning of a superstar?
A.A star has grown too big.
B.A. star is born.
C. The neutrons of a star become inadequate.
D.A massive star uses up its main nuclear fuel.
4.Questions 1 to 5 are based on the following passage.
"Fingers were made before forks." When a person gives up good manners, puts aside knife and fork, and dives into his food, someone is likely to repeat that saying.
The fork was an ancient agricultural tool, but for centuries no one thought of eating with it. Not until the eleventh century, when a young lady from Constantinople brought her fork to Italy did the custom reach Europe.
By the fifteenth century the use of the fork was widespread in Italy. The English explanation was that Italians were opposed to eating food touched with fingers, " seeing all men's fingers are not all alike clean," English travelers kept their friends laughing while describing this ridiculous Italian custom.
Anyone who used a fork to eat with was laughed at in England for the next hundred years. Men who used forks were thought to be womanish, and women who used forks were called show-offs. Not until the late 1660's did using a fork become a common custom.
1.The custom of eating with a fork was_____.
