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.

Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier,have better marriages and have more respectable occupations. Personal consultants give them better advice for finding jobs. Even judges are softer on attractive defendants(被告).But in the executive circle, beauty can become a liability.

While attractiveness is a positive factor for a man on his way up the executive ladder,it is

harmful to a woman.

Handsome male executives were thought as having more integrity than plainer men;effort and ability were thought to account for their success.

Attractive female executives were considered to have less integrity than unattractive ones;their success was attributed not to ability but to factors such as luck.

All unattractive women executives were thought to have more integrity and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was attributed more to personal relationships and less to ability than that of attractive overnight successes.

Why are attractive women not thought to be able? An attractive woman is thought to be more feminine and an attractive man more masculine(有男子气;)既的)than the less attractive ones. Thus,an attractive woman has an advantage in traditionally female jobs,but an attractive woman in a traditionally masculine position appears to lack the "masculine" qualities required.

This is true even in politics. "When the only clue is how he or she looks,people treat men and women differently," says Anne Bowman,who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women,in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again,in the order they would vote for them. The results showed that attractive males utterly defeated unattractive men, but the women who had been ranked most attractive invariably received the fewest votes.
