Exercising is a good way to keep fit. However，many people do not know how to exercise well. Here are some tips.
First，you should warm up. It is important to warm up before you exercise. You need to stretch your legs，arms，back and neck before you do some difficult activities like running.
Second，you should find good places to exercise. You do not need to spend a lot of money. You can run or do sports in a park or in your school gym. You don't need to buy exercise equipment for your home. Just get your body moving.
Third，don't work too hard. Choose a sport that you enjoy and then your exercise will be fun instead of work. Also，you only need to exercise a few times each week. If you exercise 30 minutes each time，you will stay healthy.
Fourth，drink enough water. It is important to drink water when you exercise. Your body needs the water for energy and for keeping cool.
Finally，you must be careful. If you hurt yourself while you are exercising，rest until you feel better. Exercising when you are hurt is bad for your health.

Dear Jack， How's everything going？I'm under too much pressure these days. The final exam is coming and I really want to get good grades，so I stayed up late to study for each subject during the last two weeks. I was so tired that I couldn't learn well in the daytime. Now I'm worried. Could you give me some advice？I would be very thankful if you could offer me a hand. Yours， Mike |

When people hear the word"Hollywood"（好莱坞），they often think of American movies. But when someone says"Bollywood"，what do you think of？
The word"Bollywood"is a mix of the words"Bombay"（a city in India，which is the center of the Indian film world） and"Hollywood". Bollywood is the largest movies﹣making business（商业） in India and the world. Every year，Bollywood makes more movies and money than Hollywood does.
Bollywood movies share some features（特征）. First，most Bollywood film are at least three hours long. The movie usually stops in the middle and people take a short break.
Also，many Bollywood movies are about love. Often in a story，the boy's parents don't like the girl，or the girl's parents don't like the boy. The lovers' family want to divide them，but they try to be together.
Another important part of Bollywood movies is music. Singing and dancing in a Bollywood film is very common. The music is often a mix of Indian pop songs and traditional melodies. Many people think the music is as important as the movie's story. In some Indian theaters，people watching the movie will sing and dance with the performers on screen!
— Sure. We usually eat mooncakes and get together.
There was a king who gave his daughter a beautiful diamond necklace. The necklace was missing and people in the kingdom searched everywhere but could not find it.
So the king put up notices, saying that anyone who found it could get a box of gold coins.
One day, a young man was walking along a river when he saw something shining in the river. When he looked, he saw the diamond necklace. He decided to catch it to get the reward（报酬）.
He put his hand in the river and tried to catch the necklace, but missed it. He took his hand out and looked again. The necklace was still there. He tried again. But strangely, he still missed the necklace! He started walking away, feeling sad. Just then, an old man walking by saw him, and asked him what was the matter.
The young man didn't want to share the secret with him, thinking he might take the necklace for himself, so he refused to tell him anything. The old man could see the young man was in trouble, He asked the young man to tell him the problem again and promised that he would not tell anyone about it. The young man finally told him about the necklace and how he tried hard to catch it, but kept failing.
The old man then told him that perhaps he should try looking upward, toward the tree, instead of in the river. The young man looked up, and the necklace was hanging on the branch of a tree. He had been trying to catch a reflection（倒影）of the necklace all the time.
—OK, I won't forget, mom.
