Question

根据短文内容回答下列问题。
　　Winter is coming. Another flu season is coming, too. But this year things could be a little different. Recently, Dr. David Navarro, a UN health expert(专家), warned that a new flu pandemic(世界性的流感) could come anytime. And it could kill millions of people!
　　It could be so serious because it could be a type of bird flu. Bird flu has killed at least 65 people and tens of millions of birds in Asia since 2003. Usually, the virus(病毒) does not pass from person to person. But experts believe this could change if the virus changes.
　　“If a person has human flu and also gets bird flu, the two kinds of flu could mix and make themselves into a more dangerous one,” said Aphaluck Bhatiasevi, a World Health Organization expert. To deal with this possible new flu pandemic, the Chinese government will use four colors across media — blue, yellow, orange and red — to warn people about what might happen.
　　Blue means that a new flu virus has been found in some people. But they are not ill. These people will be put in hospital.
　　Yellow means people with the new virus have become ill. The government will tell people about it and give advice.
　　Orange is when the new flu spreads from human to human among a small group of people. Then people can call a special phone number to report outbreaks(爆发). Schools and factories will be closed.
　　Red marks the most serious possibility. It means a big flu outbreak has begun.
