       In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenzalike cases. Influenza is sometimes called “flu”or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus(病毒)of this influenza.

There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups(亚群). At the hospital the doctor recognized that the outbreak was because of a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H. O. published the important news together with reports of the same kind of outbreak in Hong Kong, where about 15%~20% of the population had become ill.

As soon as the London doctors received the package of throat samples, they began to test them. They found that they could reproduce themselves at a very high speed. Continuing their careful tests, the doctor checked the effect of medicine used against all the known sub-groups of type A virus. On this virus, none of them was of any use.

Having separated the virus, the two doctors now made tests on some selected seleceted animals. In a short time the usual signs of the disease appeared. These experiments showed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply “Asian flu”.

19. The Asian flu mentioned in the passage ____.

A. had something to do with a virus group B

B. was reported to W. H. O in Geneva by a doctor in Hong Kong

C. broke out not only in Singapore but also in Hong Kong

D. was taken from the throats of the patients in a hospital in Singapore

20. London doctors considered ____. 

A. Asian flu as a bad cold

B. there were three main types of influenza

C. it was necessary to test the other groups of virus besides group A

D. the influenza called “Asian flu”a new one

21. The Singapore doctor helped the world by ____. 

A. making those with Asian flu well again

B. killing the virus that caused Asian flu

C. finding the sub-group of the virus

D. reporting the outbreak of Geneva

22. The Asian flu virus ____.  

A. was a killer

B. was very weak

C. could reproduce very quickly

D. died very fast

United States President George W. Bush is expected to issue a directive in the next few weeks. It will give the US Air Force a green light for the development of space weapons, US media reported last week.
This would potentially start a new global arms race, some experts have warned.
To keep that from happening, last Wednesday the White House explained that it was not considering putting weapons in space. It said it was making a shift in US space policy to allow for protection of satellites.
But some defense analysts and arms control advocates argue that the policy will pave the way for the US to put both defensive and offensive  weapons in space.
“No one should be fooled,” said Theresa Hitchens, an American weapons expert.
The US is now restricted by a 1996 directive  signed by President Bill Clinton. Plans for space weapons were vetoed by the Clinton cabinet. The directive emphasized the peaceful use of space , in agreement with almost unanimous global opinion.
The US military has placed importance on space and has sent up numberous satellites for troop communications and to provide intelligence and data to guide bombs to their targets.
The US Air Force wants to develop space- based weapons that could strike targets anywhere in the world within 90 minutes of receiving the order to open fire.
These new weapons under development cover a wide range. They include hunter- killer satellites and orbiting weapons. And they use lasers, radio waves, or even dense metal tubes, known as “ Rods from God”, dropped from space to do the damage.
There are many barriers to the setting up of this kind of program, experts say.
First is the coast. It is estimated that the budget may be US数学公式1 trillion .
The technical difficulties of developing reliable space weapons are also a problem.
And, the program will draw strong criticism from around the world. Experts worry about starting a space arms race
