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.

In most of the time, I am devoted to my research in the lab with my friend Dave, who loves traveling very much. To make our life colorful and relax ourselves, in July, my friend and I are taking a camping trip. We will travel for four weeks and will tour the United States and part of Canada. We have decided to camp because it does not cost as much as vacationing (度假) in hotels.
We have to plan very carefully in advance. First, the car we are going to drive is very small, so we have decided to take only one small suitcase each and as few camping things as possible. We will take some medicine with us to prevent insects (昆虫) from hurting us, and also food for picnics. Second, there is a lot to see in the United States and Canada, so we have to decide on the direction (方向) we want to drive.
The date we are leaving is July 2, from which day we will have two months off. We want to see and do many things on our camping tour. We want to climb in the mountains, visit famous caves, and swim in cool mountain rivers. We want to visit many cities and talk to many people, which I am sure can enrich our experience greatly. We also want to find a hotel room if it rains at night. We expect to have an exciting trip.
