7．　　Smiles are beautiful. A smile usually (1)            (give) people love and help.
　　On my first day of class, the teacher asked us to tell something about our names and hobbies one by one. When it was my turn, I stood up. I wanted to say something about myself, (2)             I couldn't say a word. I was afraid to speak in front of all the (3)            (classmate). Just then, a boy smiled at me and said, "Yes, you can. Take it easy." (4)            (he) smile was so warm and it made me feel better. Finally, I (5)            (do) a good job and finished my words. Later, the boy and I became good friends.
　　Now I always smile to others and everyone says I'm a happy and (6)            (friend) girl. I keep smiling because I know something small can make a big difference.

8．　　When I was 13, my only purpose was to become the star on our football team. That meant beating out Miller King, who was the best (1)       at our school.
　　Football season started in September and all summer long I worked out. I carried my football everywhere for (2)      .
　　Just before September, Miller was struck by a car and lost his right arm. I went to see him after he came back from (3)      . He looked very pale, but he didn't cry.
　　That season, I (4)       all of Miller's records (记录) while he watched the whole games from the bench (板凳). We went 10 — 1 and I was named most valuable (有价值的) player, but I often had crazy dreams in which I was to blame (因……受责备) for Miller's accident.
　　One afternoon, I was crossing the field to go home and saw Miller tried going over a fence (围栏) which wasn't hard to climb if you had (5)       arms. I'm sure I was the last person in the world he wanted to accept assistance from. But when I asked if he needed any help, he said yes. So I helped him move slowly over the fence. When we were finally (6)      , on the other side, he said to me, "You know, I didn't tell you this during the season, but you did (7)      . Thank you for filling in for me."
　　His words (8)       me from my bad dreams. I thought to myself, how even without an arm he was more of a leader. Damaged but not defeated, he was still ahead of me. I was right to have admired (欣赏) him. From that day on, I grew bigger and a little more real.

10．　　Scientists have learned a lot about the kinds of food people need. They say that there are some kinds of food that people should eat every day. They are: ①green and yellow vegetables of all kinds; ②citrus (柑桔) fruits and tomatoes; ③potatoes and other fruits and vegetables; ④meat of all kinds, fish and eggs; ⑤milk and foods made from milk; ⑥bread or cereal (谷物), rice is also in this kind of food; ⑦butter, or something like butter.
　　People in different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times. Scientists say that none of the differences is really important. It doesn't matter whether foods are eaten raw or cooked. It doesn't matter if a person eats dinner at 4 o'clock in the afternoon or at 11 o'clock at night. The important thing is what you eat every day.
　　There are two problems, then, in feeding the large number of people on earth. The first is to find some ways to feed the world's population (人口) so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.

11．　　Height is just one of the features (特征) your genes (基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall too. But if you have questions about how tall you're going to be, ask your doctor if he or she can help you find them out.
　　But genes don't decide everything. For example, eating unhealthy food can stop you from growing to your full potential (潜力). Getting plenty of sleep and enough exercise will help you grow to the expected (期待的) height.
　　Maybe you're thinking how fast you should grow. There's no perfect or right answer. Kids grow about 6 cm a year between age 3 and the time when they start puberty.
　　Your doctor will know how your growth has been going over the years. 2cm here and 3 cm there make a little difference to the height you're at now. How you have been growing up to this height? What other changes may your body be going through?
　　Don't be surprised if you seem to have grown a lot in a very short time. Everyone has a growth spurt (高峰) during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later — between 7 and 13 for girls and 9 and 15 for boys.
　　You'll usually begin to find that you're growing faster about a year after your body starts to show the first changes of puberty.

12．　　Some teenagers think that newspapers are boring and only for adults. But that's not true. There are many interesting stories in the paper.You just need to make clear what you are looking at. "I spend about half an hour reading newspapers every day," said 15-year-old Gao Ming from Beijing. "I'm interested in things happening at school." School news is just one kind of news story in newspapers. There's also world news: from international (国际的) problems to pop stars.
　　Read the newspaper carefully, we'll find different kinds of articles (文章) on the pages:
　　News stories — these stories are about events. Reporters try to show all points of a story to help readers understand what happened. Reporters try to speak to as many people as possible. They also use pictures and numbers to show the readers that the stories are true. The newspaper Teenagers has lots of news stories on the news page and front page. When we read them, we learn more about the facts, not the writers' ideas.
　　Opinion writing — opinion writing is usually about something happening right now. But it isn't just facts. Here writers add their own opinions to the news. Writers pick only the facts that help back up their ideas. They make readers believe that they are telling the truth. This is usually the kind of story that gets people thinking. Go to "Speak Out" on Page Two for an example of opinion writing in Teenagers.
　　Advertisement — Don't get happy too early when you read them. Those sweet words and lovely pictures are just ways to get us interested in their products! People have to pay to put advertisements in newspapers!

13．Shops of Goodwill
　　Have you ever heard of charity (慈善) shops? A charity shop usually sells secondhand things from people and gives most of the profit (利润)to charity.
　　Charity shops are very popular in many foreign countries. For example, in Canada, nearly every neighborhood community (社区) has one or two charity shops. People who live in the neighborhood can give away their spare (多余的)things to the charity shops. People with not much money for new things can go there to buy what they want at a low price. In many foreign countries, buying things we need in charity shops is very common.
　　In 2008, the first charity shop opened in Beijing. Starting from 2015, Beijing is going to run 66 charity shops around the city. People can give away used things, such as books, clothes and furniture (家具) to their neighborhood community. After being cleaned and sterilized (消毒), these things will be sold at charity shops. The profit will be used to help poor people in the city. Huang Dong opened his little charity shop in the downtown (市中心) area of Beijing in 2010 after he came back from Canada. He sells used books and clothes in his shop and gives most of the profit to charity organizations (组织).
　　The idea of recycling things in charity shops is a fashion in many foreign countries. They think it's a really good idea. They can help other poor people while buying things they need. We believe charity shops will also become more popular in China when more Chinese care about charity and want to do something to help others.
