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 heart, 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 that: “You use energy when you laugh, you move your diaphragm(橫膈膜), 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 laughed all day you’d 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 humor and keep smiling. Life is short anyway.

【解析】

試題分析：本文主要講了根據(jù)英國醫(yī)學(xué)雜志上的一篇文章，笑并不是最好的良藥。伯明翰大學(xué)的教授，也是這項研究的作者Professor Robin Ferner，發(fā)現(xiàn)笑得太多的人，有時會發(fā)生不好的事情。笑有時會導(dǎo)致人們出現(xiàn)心跳問題，昏倒，下巴脫臼，甚至肺爆炸。但是，笑對人來說也有一些好的方面，比如說笑能夠帶動人體熱量的燃燒，幫助人們減肥。在短暫的人生中，我們應(yīng)該保持幽默感，常常保持微笑。

1. found people with heartbeat problems which had stopped their heart, we found people who had fainted(昏倒), and we found people who’d dislocated their jaws or burst their lungs.”可知笑有時會導(dǎo)致人們信條停止，昏倒，下巴脫臼，甚至肺爆炸等問題，而笑并不能導(dǎo)致隔膜運動。故選A。

2. seems that laughing can be no laughing matter.意思是“看來笑并不是鬧著玩的，就是說笑有時不注意會給人帶來一些不好的事情。第三句Professor Ferner says there are benefits to laughing when you want to lose weighty意思是：Professor Ferner說當(dāng)你想減肥的時候，笑還是有用的。因此說明笑并不只是帶來負(fù)面的影響，還有一些積極的用處。一次此處But it’s not all doom and gloom，意思是：這并不都是厄運和憂郁。故選D。

3. if you laughed all day you’d use up about 2,000 calories,可知一整天都笑，會消耗2000卡路里，照此推算，那么半天的時間在笑的話，會消耗100卡路里。故選C。

4. give in to your sense of humor and keep smiling. Life is short anyway.意思是：所以釋放你的幽默感吧，畢竟人生短暫，常常保持笑容吧。可知作者提倡人們多笑，對笑是一種支持的態(tài)度。故選B。
