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.14Tests 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.15 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 programs.The group that tolerated(忍耐)the pain for the longest time was the group which listened to a funny program.1617They have found that even if their patients do not really feel like laughing,making them smile is enough to produce beneficial effects similar to those caused by laughter.A.Laughter is the best medicine.B.Laughter can prolong ones life.C.They have found that laughter really can improve peoples health.D.It increases blood pressure,the heart beating and breathing;it also works several groups of muscles in the face,the stomach and even the feet.E.The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.F.Although laughter helps cure the disease,doctors still cannot put this theory into clinic practice.G.As a result of these discoveries,some doctors in the United States now hold laughter clinics in which they help to improve their patients condition by encouraging them to laugh.答案1317 ACDEG二、英语知识运用(共两节,满分45分)第一节:完形填空(共20小题;每小题1.5分,满分30分)(导学号57140056)In Britain,people have different attitudes to the police.Most people generally
