Question

Next time you hear a funny joke you'd better not laugh too hard. According to a paper published by the British Medical Journal ， laughter isn't always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University  of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says, "We found people with heartbeat problems which had stopped their hearts, we found people who had fainted (昏倒)，and we found people who'd dislocated their jaws or burst their lungs."

It seems that laughing can be no laughing matter. But it's not all doom and gloom. Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that's right: laugh and be slimmer! Professor Ferner explains, " You use energy when you laugh, you move your diaphragm(橫JH膜)， you expand your lungs, and both those things can be helpful.，，

According to the research, laughing for a quarter of an hour can burn up to 40 calories, and if you laugh all day you'll use up about 2， 000 calories, which is what most people consume in a day. But don't do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way.

But I don't want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3〜6 months. So give in to your sense of humour and keep smiling. Life is short anyway.

B 細節(jié)理解題。根據(jù)第一段"He says, ' We found people with heartbeat problems which had stopped their hearts, we found people who had fainted (昏倒)，and we found people who'd dislocated their jaws or burst their lungs."，可知，笑的危害有心臟驟停、昏倒、下巴脫臼及會傷到肺，故B項沒有提到。

A 詞義猜測題。根據(jù)第二段"It seems that laughing can be no laughing matter. But it's not all doom and gloom. Profes?sor Ferner says there are benefits to laughing when you want to lose weight, for example."可知，笑并不是無用的，教授說，當你想減肥時，笑是非常有效的，故選A項。

B 推理判斷題。根據(jù)第三段"…if you laugh all day you'll use up about 2， 000 calories, which is what most people con?sume in a day."可知，笑一天消耗2000卡路里，那么笑半天就是1000卡路里，故選B項。
