The 2009 outbreak of HINI is a new kind of influenza virus, commonly referred to as “swine flu”. It is thought to be a break of four known kinds of influenza. A virus subtype H1N1: one endedmic(流行病) in humans, one endemic in birds, and two endemic in pigs (swine). The source of the outbreak in humans is still unknown, but cases were first discovered in the U.S. and soon after in Mexico.

According to the U.S. Centers for Disease Control and Prevention(CDC)，it is not yet clear how serious this new virus actually is compared with other influenza viruses, although on May 26 they stated that new cases in the U.S. have probably reached the hightest point, and most cases have so far been mild relative to “seasonal flus”. But because this is a new virus, most people will not have immunity(免疫性) to it, and illness may eventually become more severe and widspread. The H1N1 flu mainly spreads in the same way that regular “seasonal influenza” spreads through the air from coughs and sneezes or touching those infected. It cannot be transmitted from eating cooked pork or by being in close contact with pigs.

As yet there is no vaccine(疫苗) available to prevent infection although companies are in the planning stages for having one available later this year. But there is concern that the virus could vary again over the coming months, leading to a new and potentially more dangerous flu outbreak later in the year, and a vaccine that will be less effective in preventing its spread.

As of May 27, the virus had spread to more than 50 countries; however, over 80% of reported deaths have taken place in Mexico. According to the CDC, the fact that the flu’s infection activity is now monitored more closely may help explain why more flu cases than normal are being recorded in Mexico, the United States and other countries.    

1. The 2009 outbreak of H1N1 is thought to      .

A.be concerned with four endmics                                             

B.have come from the virus from pigs

C.occur because of unknown virus in Mexico

D.be caused because of people without immunity

2.According to the U.S. Centers for Disease Control and Prevention, ______.

A.most people won’t be infected with the flu                                           

B.the H1N1 will not be too mild to cause many deaths in the world

C.the present situation allows of no optimist

D.H1N1 can be transmitted by touching pigs                             

3.To make people worried more is that      .

A.no effective vaccine can prevent the virus from spreading

B.the virus will mutate in the following months

C.a seasonal influenza will break out

D.the newly-developed vaccine will lose effectiveness

4.From the passage we can learn that      .

A.every country is watching closely the spreading of the H1N1                        

B.more than one-fourth of the deaths from the H1N1 are in Mexico                          

C.only the United States and Mexico recorded the cased of influenza                                                                     

D.effective medicine has been produced to cure the H1N1         

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.

Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?

As pointed out at the beginning of the passage, people used to think that air pollution _______.

A. cause widespread damage in the countryside

B. affected the entire eastern half of the United States

C. had damaged effect on health

D. existed merely in urban and industries areas

As to the greenhouse effect, the author __________.

A. share the same view with the scientist.

B. is uncertain of its occurrence

C. rejects it as being ungrounded

D. thinks that it will destroy the world soon

The word “offset” in the second paragraph could be replaced by _________.

A. slip into   B. make up for　　 C. set up    D. catch up with

It can be concluded that ____________.

A. raising the world’s temperature only a few degrees would not do much harm to life on earth

B. lowering the world’s temperature merely a few degrees would lead major farming areas to disaster 

C. almost no temperature variations have occurred over the past decade

D. the world’s temperature will remain constant in the years to come

This passage is primarily about __________.

A. the greenhouse effect        　    B. the burning of fossil fuels

C. the potential effect of air pollution  　D. the likelihood of a new ice age

    Since weeks ago, China has been involved in a worldwide A/H1N1 flu that has already killed more than 80 people in the middle of May, 2009, in Mexico and has turned into a global pandemic．

   The central government has asked people entering China from the virus-hit countries to report flu-like symptoms(症状)to the authorities．In an emergency notice issued on Saturday night, the country’s top quality watchdog ordered the Customs to check passengers’ temperature, too．

   A Beijing airport official Li said Customs officers are on a high alert(警戒)level．

   “Three temperature detectors are now in operation．We’re ready with protection garments and equipment, too．Passengers flying in from Mexico and other A/H1N1 flu-hit countries are being monitored closely,” he said．

   The Ministry of Health, however, said yesterday there was no evidence to suggest that a person would contract the disease by eating pork．

   Hong Kong, too, has raised its alert level against the flu to “serious”．Secretary for Food＆Health, Mr．York Chow urged people to avoid visiting places from where A/H1N1 flu cases have been reported, and said the virus would be added to Hong Kong’s list of the diseases which have been noticed．

  The terrible A/ H1N1 flu has been contracted by about 4000 people in Mexico, and most of the killed were aged between 25 and 45．

  The virus has also infected about 5,000 people in the US．The US Center for Disease Control said this kind of virus is spreading from human to human, raising fears of a global pandemic．

53．What is the passage mainly about?

       A．A/H1N1 flu killed more than 80 people．

       B．A/H1N1 flu is spreading from human to human．

       C．China has begun to take steps to prevent A/H1N1 flu．

       D．All the people are strongly affected by A/H1 N1 flu．

54．The underlined word “pandemic” in the first paragraph probably means      ..

       A．death    B．panic    C．enemy      D．disease

55．Why does the flu cause global fears?

       A．Because most people in the world eat pork．

       B．Because it’s spreading from human to human．

       C．Because we still don’t know the cause of it．

       D．Because it has infected about 5, 000 people．

56．We can infer from the passage that         ． 

       A．passengers from the United States are being monitored closely

       B．a person would be infected by the virus by eating pork

       C．students in the middle school are most likely infected by A/H1N1 flu

       D．Mr．York Chow said that the virus had been added to Hong Kong’s list of the diseases
