Life has changed in Mexico City. Streets normally filled with people are empty. One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than 100,000 people. It's swine(猪)flu that has made life in Mexico City grind to a halt. Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30. It has sent a wave of alarm around the world. Governments are trying to find ways to prevent further outbreaks. The World Health Organization has raised its swine flu global threat level to five out of six.
People may be familiar with bird flu,but they know little about swine flu. Swine flu is a contagious (传染性的)respiratory(呼吸的)disease in pigs. It is caused by a type-A influenza virus.
Humans can also catch swine flu. The virus causes regular outbreaks in pigs，but people usually do not catch it. However, there have been cases of the virus spreading to people, and then from one person to another.
The symptoms of swine flu are similar to the common flu. They include fever, lethargy (无精4丁采).lack of appetite, coughing,runny nose, sore throat, nausea (恶心).and vomiting ("区吐). The high proportion of young adults among the deaths is one of several mysteries about this virus. Most of the dead had lung damage. What caused it is not yet known.
The virus spreads the same way the common flu does. When an infected person coughs or sneezes around another person, the latter is put at risk. People can get the disease by touching something with the flu virus on it and then touching their mouth,nose or eyes.
There are medicines to treat swine flu. Doctors suggest using anti-viral drugs. They keep the virus from reproducing inside the body.
Although there are no vaccines for it now,several everyday steps can help prevent the spread of the virus: washing hands frequently;avoiding close contact with people who are sick;and avoiding touching surfaces that might have the virus on it.
People may worry that they will get swine flu from eating or preparing pork. In fact,you cannot catch the virus from pork products if they have been properly prepared and cooked. Cooking food at temperatures of 71 ^ kills the virus.

8. D主旨大意题。文章首句告诉读者墨西哥城的生活发生了变化，随后举例证明了这一变化，最后一句给出结论是猪流感导致了这一变化。
9. C词义猜测题。从"One of the most popular pro fessional soccer teams recently played a game in an empty stadium that can seat more than 100,000 people." 可知，墨西哥城的生活显然是因猪流感而变得没有生机。A项(停下来)过于绝对；B项(仍然生机勃勃)与文意相悖；0项(陷入安静)仅表示一种方式而已。
10.A事实判断题。短文没有提到A项。B、C、D 项见倒数第二段表述。
11.A逻辑推理题。通过"Although there are no vac?cines for it now"可以推断出结论A。B项表述与第四段表述相悖；C项表述与最后一段表述相悖；D项表述与"Most of the dead had lung damage" 表述相悖。
12.B主旨大意题。短文开篇讲述了墨西哥城市民的生活因猪流感而改变，接着讲猪流感的传染对象，随后讲猪流感的症状，以及猪流感的传播途径，最后讲猪流感的治疗方法和预防途径。所以，全篇谈的都是有关猪流感的信息。
