How is this virus transmitted?

This is an outbreak of disease that started in Wuhan, one of the central Chinese cities. It’s caused by a novel coronavirus that means it’s brand-new. 1.

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, ______.

3.To make people worried more is that ________.

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

The largest outbreak of the deadly disease Ebola(埃博拉) was caused by an infected bat biting a toddler, say a group of international researchers.

The 17-strong team of European and African tropical disease researchers, ecologists and anthropologists have spent three weeks investigating the outbreak of the disease in Guinea, Liberia, Ivory Coast and Nigeria. The researchers captured the bats and other creatures near the village of Meliandoua in remote eastern Guinea, where the disease began in December 2013. The boy was bitten and passed the infection on to his mother and both died within a week. The disease was then spread far and wide by the people who came to the funeral.

Most of the previous outbreaks have been caused by meat from dead infected animals collected by hunters who then sell it on. Fruit bats, however, are widely eaten in rural West Africa.

The team, led by epidemiologist(流行病学家) Herr Leendertz, a disease ecologist at the Robert Koch Institute in Berlin, are expected to publish their results in a major journal soon.

Herr Leendertz’s team believe that an infected straw-colored fruit bat brought the disease to Guinea. The mammals are known to travel long distances and usually settle in forests near cities. Herr Leendertz said, “ The evidence is not 100 percent and we can only say that it is possible. They can travel far in one night. I don't think an individual bat or colony(群体) migrated all the way from Congo or Gabon to West Africa. These big colonies are connected. There is a possibility for the virus to mix between colonies. The bats share the same fruit. It is likely not to have even been one species of bat. The virus may jump from one species to another."

If the bat theory is confirmed, the locals would try to destroy the colonies, which, Herr Leendertz says, would be an ecological disaster, because bats pollinate(传授花粉) plants and kill insects. And bat hunts would also only increase human contact with potentially infected animals.

1.What’s the purpose of the 17-strong team?

A. To look into the outbreak of Ebola.

B. To help the people who suffer from Ebola.

C. To help cure the infected boy of Ebola.

D. To make a study of the bats including fruit bats.

2.In Herr Leendertz’s opinion, ______.

A. people can do nothing to prevent the disease

B. the disease Ebola may jump from one species to another

C. the result of the research should be published immediately

D. the straw-colored fruit bats usually settle in forests in the rural areas

3.If the bat theory is confirmed, ______.

A. the disease Ebola will be controlled

B. all the fruit bats in Africa would be killed

C. plants would not be pollinated in the future

D. the ecosystem in Africa might lose its balance

4.What’s the main idea of this passage?

A. A toddler was bitten by a bat and died.

B. The disease Ebola is incurable at present.

C. An infected bat caused the outbreak of Ebola.

D. The deadly disease Ebola broke out in Guinea.

5.This passage can probably be classified as ______.

A. a science fiction　　　　 B. a news report

C. a lecture essay　　　 　 D. an auto-biography
