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 study laughter and the effects (作用) 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 helpful.
Other tests have shown that laughter appears to make the effect of pain on the body less. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which could bear the pain for the longest time was the group which listened to a funny program. The reason why laughter can make pain less seems to be that it helps to produce endorphins (内啡肽) in the brain. These are natural chemicals which make both stress and pain less.
There is also some evidence to suggest that laughter helps the body’s immune system that is the system which fights infection (感染). In an experiment, one group of students watched a funny video while another group served as the control group — in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells that is the cells which fight infection.
As a result of these discoveries, some doctors and psychiatrists (精神病学) in the United States now hold laughter clinics, in which they try 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 good effects similar to those caused by laughter.We learn from the first paragraph that laughter .

China has banned（禁止）free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1.It came because our country tried to make litter less. Making super-thin（超薄）plastic bags has also been banned.

Everyone needs friends. There is an old saying: Friends are God’s way of taking care of us. But how do you find real friendship and keep it?
“The Care and Keeping of Friends” by American author Sally Seamans tells young students some smart ways to find friends.
Sally says finding friendship is just like planting a tree. You plant the seed and take care of it to make it grow.
First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend should listen to your complaints(抱怨) and do their best to help. To make a friend, you cannot be too shy. You should make each other happy and share your lives.
But things cannot always be happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to them. When there is no one around, have an honest talk. If he or she doesn’t want to talk, you could write a letter.
Sally says there are three steps to being friends again: Tell him or her how you are feeling; say what your friend has done wrong, and explain why you did this or that. The book also has advice on some small but important things like celebrating your friends’ success. Even if you haven’t had a real friend before, you will start to think of having one if you read this book. Because the book tells that friendship is the most important thing in your life.The writer of the text really wants to tell us________.
