(单选题)

We can learn from the passage that Doctor Nelson ______.

A.doesn’t believe in the old advice about preventing colds

B.is now trying his best to provide proofs for long-held beliefs

C.doesn’t think it necessary to see a doctor immediately if a person has a temperature of 40℃

D.doesn’t think it necessary to treat a fever even if it prevents someone from sleeping

参考答案：C

参考解析：

细节理解题。文章倒数第二段第二句“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。故选C。
