单选题 Colds are very common. The symptoms of the common cold include a sore throat, runny nose, stuffed-up nose, and tiredness. Colds are caused by viruses, but scientists cannot explain the exact cause. There is no cure. Many people, however, believe that they know the causes of and cures for the common cold. For example, they believe that it is possible to get a cold if we get chilled, if we get extra tired, or if we are too close to a person with a cold. In other words, if we want to prevent catching cold, we should stay warm and dry; we should avoid getting too tired, and we should not be in close contact with people who have colds.
Meanwhile, there are probably hundreds of " cures" throughout the world for the common cold. For example, the following suggestions are popular in quite a number of societies : (1) drink plenty of water; (2) get extra rest; (3) take a lot of vitamin C; (4) take aspirin; (5) keep warm.
Each year people spend a lot of money on cold medicines-pills, liquids, lozenges (含片). But these medicines do not cure colds; they can only relieve cold symptoms. In other words, they make us feel better.
