1．There is an English saying that"Laughter is the best medicine．"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．They have found that laughter can really improve people's health．
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．It increases blood pressure，makes the heart beat quicker and makes people breathe deeper； it also works on several groups of muscles in the face，the stomach，and even the feet．If laughter exercises the body，it must be beneficial．
Other tests have shown that laughter appears to be able to reduce the effects 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．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain．
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．They 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．
32．What do we learn from the tests mentioned in paragraph 2？C
A．Laughter has totally different effects when compared with physical exercise．
B．Laughter can help to decrease blood pressure．
C．Tests'purposes were to study the influence of laughter on the body．
D．Laughter makes no difference to our feet．
33．The underlined word in paragraph 3can be replaced byD．
A．increase      
B．raise      
C．add       
D．reduce
34．According to the passage，the following statements are true exceptC．．
A．Laughter is good for health．
B．Laughter helps to reduce pain．
C．Laughter can make you become old．
D．Laughter has good effects on patients．
35．The best title for this passage may beD．．
A．Both laughter and physical exercise are good for health
B．Laughter clinics help patients improve their condition
C．Laughter can reduce the effects of pain
D．Laughter is the best medicine．
