Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, “feed a cold and starve a fever?” And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable?
Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside.
And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water.
Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at
40℃ or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping.
Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems.

(答案→)C
解析：
【小题1】推理题：从文章第四段的句子Nelson says a fever should be treated if it stays at 40℃ or above for a day or more. 说明如果发高烧达到40度以上长达一天多，就要治疗了，也就是如果刚刚发烧达40度，就没必要治疗。选C。
【小题2】细节题：从文章第三段的But drinking enough water is important. 可知喝水很重要。选B。
【小题3】排除题：A项是出现在第四段。同第一题的解析，文章的第二段Nelson says research may be just starting to provide proofs for long-held beliefs. 说明B项正确，文章最后一段的Medicine like aspirin, for example, can be used to reduce pain and fever.说明C项正确，就是没提到D。
【小题4】细节题：从文章的最后一段的：But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses.说明身体有压力的时候很容易生病。选B。
