There are so many bikes, cars and buses on the roads, so we must obey the traffic rules all the time.

    Children under 12 cannot ride bikes on the street. When we ride bikes, we should keep both hands on the handlebars(把手).①We should ride bikes on the right of the road in our country.

    ②Like drivers of cars or buses, we must follow(遵循) all traffic signs. All of us know we must not turn left or go across the street at a red traffic light. Usually we can turn right, but we shouldn't ride too fast. If we want to turn or stop, we must give a sign to others.

    Sometimes it may seem difficult to improve our health. If so, the following health habits may help you.

    Eat breakfast every morning

    Research(研究) shows that if you eat a meal in the morning, you may not become too fat or eat too much during lunch. Eating breakfast can help people feel better through the day.

    Get enough sleep

    Poor sleep can influence(影响) our memory and learning. It can also cause traffic accidents! Studies show that people who don't get enough sleep seem to get into more accidents. So stay safe and get enough sleep!

    Take a walk every day

    Walking is an easy way of exercising. You'd better meet friends for a walk, not for a meal. As you walk, you will see the beautiful world around you. Once you try, you'll find that adding a walk into your daily life is very easy.

    Join social groups

    Social groups can provide support. They might include sport teams, art or music groups. The people in the group can offer advice and can help each other in difficult times. Also, being in a group keeps your mind busy. And active mind is a healthy mind.

    Have a hobby

    A hobby could be running, reading or making something with your hands. Hobbies help people to relax and rest. Hobbies bring us joy, too.

    In English, people use many expressions(表达) with the word "dog". People in the west love their dogs and treat them well. Dogs without owners to care for them lead a very different kind of life: The expression' to lead a dog's life" means living an unhappy life.

    Some people say we live in a dog-eat-dog world. That means many people are competing the same things, like good jobs. They say if a person wants to be successful he has to work like a dog. This means they have to work very hard. Such hard work can make people dog-tired. And, this situation would be even worse if they became ill as a dog.

    Sometimes we should let a sleeping dog lie, which means we'd better not trouble a person who may cause problems. And if someone says you are a lucky dog, he is just saying you're very lucky.

    Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people Often have to learn new skills(技能) . Yet, some people say that it's always impossible to teach an old dog new skills. They believe that older people do not like to learn new things and will not change the way they do things.

    There are also some other dog expressions. The dog days of summer are the hottest of the year. A rain in summer may cool the weather. But we do not want to have a very heavy rain. In other words, we do not want it to rain cats and dogs.

Dear Miss Zhao,

    Thank you for introducing the summer camp program to me. This program is organized by Yueyang Education and Sports Bureau (岳阳市教体局). It has brought over 500 middle school students to the countryside to experience the life here.

    We have been in this small village for six days. Every morning we get up early, breathe the fresh air and hear the birds sing in the woods. 我们一走出房子，就可以看到花、草、树木和动物。 We go for walks through the countryside and watch the villagers do their daily activities.

    Li Guoqing, a sixty-year-old villager says, "Thanks to the government, great changes have taken place in the countryside. People mustn't cut down trees or build houses on the farmland (农田). Anyone is not allowed to make our rivers or lakes dirty. All villagers are supposed to put rubbish in the bin."

    We really enjoy the trip and come to realize the importance of protecting the environment. 每个人都应该参与保护环境。 If the environment is taken good care of, we'll have a cleaner and greener world. The clean water and green mountains are our treasures.

Yours truly,

He Wei

    One of the easiest ways to keep healthy is to do jogging. Jogging is the name for very gentle (平和的) running-it is just a little faster than walking.

    First jog slowly 20 meters, and then walk 20 meters. Little by little if you are not feeling very tired, you may jog more and walk less. Finally, jog the whole way. It will be easy for you to start jogging for 15 minutes twice a week. Then slowly increase this to 20 ~ 30 minutes every day. The longer you join in jogging, the more you will enjoy it and the healthier you will become. Some people like jogging alone and others enjoy doing it with friends. Jogging in groups makes people keener (更热心的) because you just can't stay in bed while there is a group of friends waiting outside.

If you want to start jogging, prepare a pair of comfortable shoes and a determined(坚定的) mind.
