    IV.閱讀填空

    There is an English saying “ 1 ” Until recently, few people took the saying seriously. Now,however,doctors have begun to look into laughter and the effects it has on the human body. 2

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts,blood pressure,breathing and muscles. It was found that laughter has similar effects to physical exercise. 3 If laughter exercises the body,it must be beneficial.

    Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme. 4

       A. Laughter can prolong one's life.
