Wang Tao's Summer Holiday

    My summer holiday of this year was very enjoyable. I went to the countryside to spend my summer holidays with my grandparents. It is very beautiful there. There are green plants, clear rivers, lovely animals and kind people. I spent two weeks helping my grandfather do some farm work there. Besides, I helped the children in the neighborhoods with their lessons. I helped them read English to improve their spoken English. Their parents thanked me for this and thought highly of me. I realized that knowledge is greatly needed in the countryside.

    Good sleep is important to your health. You need about eight hours' sleep a night. Don't eat or read in bed. A cup of milk before sleep may help you get a good sleep. Go to bed at the same time before midnight and get up all the same time every morning.

    How often do you exercise? If you want to stay healthy, try to exercise for 30 minutes every day and three or four times a week. For more information, please call Health Line at 180-2000.

    Eating habits are also important to us. You should have more fruit and vegetables every day. And you shouldn't eat too much or too little. Of course, you should keep away from fast food. If you want to know more, please call Dr. Smith at 6831918.

Brush your teeth twice a day and see a dentist at least once a year. The oral(口腔) examination is not only for the health of teeth, but also for the whole body.

    International travelers, whether traveling for business or pleasure, will find themselves alone from time to time. Here are a few ways to meet new people and perhaps even get new travel chances.

{#blank#}1{#/blank#}⑴Be polite and friendly. Remember to put yourself in social situations. Restaurants, shops and parks are all great places to meet people. If you want to make local friends in a country, stay near the places the locals often visit.

{#blank#}2{#/blank#}⑵Keep a small photo album in your bag when you travel. Photos of family, friends and pets will help your new friends learn more about you. They will share their similar experiences with you, and it will help you learn more about your new friends.

{#blank#}3{#/blank#}⑶Can you help your new friends improve their Chinese? Can you cook a traditional Chinese meal? By sharing your experiences, you can have a close relationship with your new friends that they won't soon forget.

{#blank#}4{#/blank#}⑷Many foreigners love Chinese goods but have to pay a lot when buying them in homeland, so you'd better prepare some gifts such as silks, tea and china (瓷器). They are always popular.

{#blank#}5{#/blank#}⑸If you and your new friends get along well, you can give them your information and plan to live in each other's house for your next trip. Then you can visit their countries and stay in their houses while they stay in yours. In this way you will improve your friendship and live like a local abroad, but pay less for traveling.

Information Card

    I'm a 34-year-old man, married, lived in a nice house, and have a successful career. But my life was not always so great. I had a learning disability from an early age. I went to a special school where I got plenty of extra(额外的)help. Still, I suffered(遭受)the rest of my school days in public schools.

    My life improved greatly when I discovered art. The art world gave me a chance to express myself without words. I went to a workshop and gradually became good at making things with clay. Here I learned my first important lesson: disabled as I was in language, I could still be smart and well express myself with clay. And my confidence(自信)came along.

    I got my next lesson from rock climbing. It was a fun thing but I was scared from the start. I soon noticed it wasn't an easy thing: it needed lots of practice. So I did it more. After about five years of climbing, I found myself in Yosemite Valley on a big wall. I learned that if you fall in love with something and do it all the time, you will get better at it.

    Later I decided to learn how to read and write. I practiced reading and writing, which I used to avoid as much as possible. After two years, I was literate(有文化的).

    Through the long process with art, climbing, and reading and writing, now I've got to a point in my life: I am smart enough to dive into(潜入)an area that is totally unknown, hard, but interesting.
