A smile will tell people around you that you are a kind and friendly person. However, many people don’t smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn’t have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others’ teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them.
Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now.

　　Why was his big idea so successful? Maybe the most important reason was that his timing was right. In the 1950s, most married women stayed home to keep house and take care of their children. In the 1960s, many women returned to the workplace. This meant that they had less time and energy to do housework and preparation for meals so they relied more on “TV dinners” and fast-food restaurants. Single parents also have little time to spend in the kitchen. People living alone also depended on this kind of food, since cooking for one causes often more trouble than it is worth.

　　Fast food is not part of the diet of all Americans. Another trend of the 1960s, sometimes called the back-to-nature movement influenced many people to avoid food that was packaged or processed. This preference for nature food continues to this day.

　　From the success of Raymond Kroc's fast-food business, we can say the social economic trends influence where and what we eat.

（　）4. Why was McDonald's idea so successful? It was mainly because ________.

A. people living alone depend on fast-food

B. single parents have little time to spent in the kitchen

    When I was a child, my mother often told me, “Don’t run around, or bad uncles will grad（抓住） you. And you know what? You will never see Mum and Dad again.”

    “Why, Mama? Why would these uncles grab me?” I would ask. “The city is a dangerous place and we don’t trust any strangers, ”she would reply.

  Well, that might answer the question of why my second brother never picks up calls from an unknown person either on his mobile or his home phone. It seems that he doesn’t care if he misses an important call. because he thinks that all unknown calls are from bad persons.

    So, have we given too much protection to our young kids? Perhaps it is so. But the adults’ thoughts are indeed easy to understand. The kids meet swindlers sometimes as we adults tell them. Also they get some news about cheating（欺騙） in newspapers or on TV every day. That makes the kids believe that they just cannot trust strangers.

    Let’s look at an example from everyday life. Say, if someone carrying a wooden stick（棍子） comes nearer to you, will you try to run away at once even before he or she starts talking to you? Will you guess this person’s intentions（意圖） and think that he or she wants to rob（搶劫） you of something? Think of the answer for yourself.

    Of course, the kids should look after themselves, but overprotection can sometimes stop them from making new friends. Sometimes it’s not good for their new friendships.

    Trust is like a mirror. When we offer trust to people, they might just show you trust in return.

1 What do “swindlers” probably do?

  A. They cheat other people.

  B. They often call other people.

  C. They rob people of something.

  D. They teach children to protect themselves.

2 Which of the following is NOT the reason why children don’t trust strangers?

  A. Their parents tell them not to trust strangers.

  B. They get to know some news about cheating in newspapers or on TV every day.

  C. Strangers always have bad intentions.

  D. They sometimes have experiences of being cheated.

3 What does the writer want to tell us?

  A. Children should always follow their parents’ advice.

  B. We should never talk to strangers.

  C. Parents should learn to protect their children.

  D. People should try to trust each other.
