As we know, it is common for people to catch a cold in winter and most people believe they know the reason for colds. However, scientists say people have some wrong beliefs about the cause of colds.
Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That’s not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter. That is also wrong.
It’s because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes, sneezing, or coughing.
While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold.
In addition, if you do have a cold and you don’t feel like eating anything, it’s not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That’s very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you.

轻松暑假总复习系列答案Unless we spend money to spot and prevent asteroids now，one might crash into Earth and destroy life as we know it，say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one，the scientists say，we'll have a way 
to change its course.
Some scientists favor pushing asteroids off course with nuclear weapo
ns. But the cost wouldn't be cheap. I
s it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “If we don't take care of these big asteroids，they'll take care of us,” says one scientist. “It's that simple.”
The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.
