Today, when a man steps on to the moon, or something new and important happens, the world learns about it immediately. What did the newspapers say about that first flight in 1903? Strangely enough, they said hardly anything about it at all. There were only a few reports about it in the papers. These reports said very little. Some of the things they said were not even correct.

　　In 1904 the Wrights built a second machine. They called it "Flyer No. Two". They invited some reporters to a field near Dayton to watch them fly. Unfortunately there was some mechanical （机械的）trouble with the plane and it did not fly at all that day. The newspapermen went away. They were disappointed and did not come back. The Wrights went on with their work. In 1905, they built an even better machine, "Flyer No. Three". They were able to stay upon the air for half an hour and more in the machine and they were able to turn and climb in the air. Farmers and travelers on the road around Dayton often saw them flying. But when these people told newspapermen about it, they refused to believe them.

　　The Wrights offered "Flyer No. Three" to the United States govern ment. The government was not interested. They seemed to think the Wrights wanted money in order to build a plane. They did not understand the Wrights had already done this, and flown it as well. Experts were still saying that mechanical flight was impossible. At the end of 1905, the two brothers took their plane to pieces. The parts were put into a huge wooden box. It seemed nobody was interested.

　　　　A. were not carried in any newspaper

　　　　B. they saw the Wrights failed to fly "Flyer No. Two"

　　　　C. they had never seen a machine that can fly

　　　　D. all the above

　　

　　3．The U. S. government could not understand that __________

　　　　A. the Wrights had already built a machine that could fly

　　　　B. experts still thought flight was impossible

　　　　C. the Wrights wanted more money to build an airplane

　　　　D. "Flyer No. Three" was then in a woken case

　　

　　4．The Wrights took their plane to pieces because ________.

　　On June 5,1981 the Centers for Disease Control in Atlanta, U.S. announced the presence of a rare, infectious disease in five American homosexuals（同性恋）. Soon doctors were finding similar cases all over the country and the world. The AIDS epidemic（流行病）had officially begun. By 1983 it was clear that AIDS had spread around the world. More than twenty years later, AIDS has left twenty-six million dead and another forty million infected. AIDS has come the worst medical disaster ever experienced by mankind.

　　Hundreds of young people between the ages of 20 and 45 died each week during the early years of the U.S.AIDS. More than 600000 cases of AIDS have been reported since 1981 in the United States, and it is estimated that there may be as many as 900000 Americans infected with HIV.

　　Though the rate of HIV infections continues to increase in the United States, the number of AIDS cases has fallen sharply since 1996, when antiretroviral drugs came into the market Unfortunately, the AIDS epidemic continues today in Africa and much of Asia, where antiretroviral treatment is not available and health care is far from enough. AIDS is the fourth leading cause of death worldwide, and the No.1 cause of death due to infectious disease.

　　HIV, the virus that causes AIDS, was first separated in 1983 by a team at the Pasteur Institute in Paris. That discovery made it possible to develop a test for AIDS and trace back to victims who may have died before doctors were aware of the disease.

　　However, scientists still don't know exactly how and where AIDS started. Finding the source of AIDS could be important in developing a vaccine（疫苗）and be important in mapping the future course of the epidemic.

(1) It can be inferred from the passage that ________.

[　　]

A．antiretroviral drugs will be obtained easily all over the world

B．the best way to stop AIDS is to develop a vaccine

C．scientists will soon find a way to cure AIDS

D．there will be fewer AIDS cases in the world in the future

(2) The number of AIDS cases has greatly decreased in the United States due to the fact ________.

[　　]

A．a team at the Pasteur Institute in Paris succeeded in separating HIV

B．some effective medicine has been invented

C．scientists understand AIDS better and better

D．the rate of HIV infections continues to rise in the United States

(3) What's the importance of the discovery of the source of AIDS?

[　　]

A．It can be used to develop a test for AIDS.

B．It can stop HIV forming AIDS.

C．It can reduce the rate of death caused by AIDS.

D．It can help develop a drug to prevent

(4) When did the name of AIDS come into being?

　　Milk was one of the main human foods long before history was written. It will probably remain one as long as there are animals that give milk.

　　The old word “milk” came from Sanskirt (梵文) , one of the oldest languages known to man. A very old picture of milking has been found. It was drawn five thousand years ago.

　　In the years long ago, people got their milk from their own animals. But in modem times new inventions made the milk industry a big business. In 1851 Gall Borden found a way to take some of the water from milk. This made it keep longer. Four years later, Louis Pasteur introduced a way to kill the bacteria (细菌) in milk. Next, a special milk bottle was made. This was followed by the invention of machines that could fill bottles with milk.

　　These discoveries had a great effect on the industry. They meant that milk could be stored longer.

　　Some people believed that milk drinking will become less popular than it has been, but remember how long milk has been an important food and think of the many ways in which it is useful. It seems safe to say that milk industry will always be important.

1．People began to milk animals ________.
