There is an old saying in English : "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now, however, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can 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 heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing; it also works 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 capable of reducing the effect of pain on the body.There is also some evidence to suggest that laughter helps the body’ s immune system, that is, the system which fights infection.As a result of these discoveries, some doctors and psychiatrists (精神病学家) in the United States now hold laughter clinics, in which they try to improve their patients’ condition by encouraging them to laugh.1) Laughter really can (1) 2) In the first test, it was found that laughter has similar effects to (2) 3) Other tests have shown that laughter can reduce the effect of (3) on the body.4) There is evidence to show that laughter helps the body’ s (4) 5) In the clinics, the psychiatrists try to improve their patients’ condition by encouraging them (5) 4()

Scientists can determine someone’ s favorite food from their body shape. They have discovered that the arrangement of taste buds(舌部味蕾) on the tongue varies for different body types. The scientist team examined 1,000 British adults and divided them into three physiologically recognized body types-ectomorphs, endomorphs and mesomorphs. They determined that a person’ s body type indicated where they were likely to have the most taste buds on the sweet, bitter or salty areas of their tongue.The study showed that ectomorphs, who make up one in three of the population, usually have a small delicate shape, have a sweet tooth but hate bitter foods. Mesomorphs, who make up 20 percent of the population, usually have a muscular shape and prefer salty or bitter foods but dislike sweet foods. Half the British population are endomorphy with soft, rounded bodies, and they like most foods. The findings showed that for two in three people food preference was a physiological rather than a psychological choice.Body shape expert Simon Bradshaw, who takes charge of this team, said : "It appears that simply by looking at an individual’ s body shape we can make sure about their preferences. " But Catherine Collins, of the British Dietetic Association said:" It is difficult to dictate whether our body shape dictates the food we like, or the food we like dictates body shape. " It stands to reason people who prefer most types of foods will be fatter and people who are the endomorph shape tend to find it more difficult to lose weight. "It stands to reason" in the third paragraph means "()".
