“How are you?” is a nice question .It’s a friendly way that people in the U.S.A greet each other. But “How are you?” is also a very unusual question. It’s a question that often doesn’t need an answer. The person who asks “How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine ”isn’t really an answer. They are simply other ways of saying “Hello” or “Hi”.
Sometimes ,people also don’t say exactly what they mean. For example, when someone Asks “Do you agree?” ,the other person might think, “No, I disagree. I think you’re Wrong...”But it isn’t very polite to disagree so strongly, so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.
People also don’t say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person say “I’ve to go now. ”Often, the person who wants to hang up gives and excuse:“ Someone’s at the door.”“Something is burning on the stove.” The excuses might be real, or not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite ,and it doesn’t hurt the other person.
Whether they are greeting each other, talking about an idea, of finishing a talk, people don’t say exactly that they are thinking.

Sam and Joe were astronauts. There was once a very dangerous trip and the more experienced(有经验的) astronauts knew there was only a small chance of coming back alive. Sam and Joe, however, thought it would be exciting though a little dangerous. “We’re the best men for the job,” they said to the boss. “There may be problems, but we can find the answers.” “They’re the last people I’d trust(信任),” thought the boss. “But all the other astronauts have refused(拒绝) to go.”
Once they were in space, Joe had to go outside to make some repairs(维修). When the repairs were done, he tried to get back inside the spaceship. But the door was locked.

A punctual person is in the habit of doing a thing at the correct time and is never late for anything.
An unpunctual man never does what he has to do at the right time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be got back. Time is more useful than material things. In fact, time is life itself. An unpunctual man is always wasting his most important things as well as others'. An unpunctual person is always saying unhappily that he finds no time to answer letters or return calls. But the man who really has much to do is very careful of his time. He knows that he can not finish all his work unless he carefully does every piece of work.
Being unpunctual is the sign of disrespect (不尊重) towards others. If a person is invited to dinner and arrives later than the time when he should be there, he keeps all the other guests (客人)waiting for him. Usually this will be thought as a great disrespect to the host and all the other guests.
Not like a punctual person, an unpunctual one can't do his duty wonderfully, whether it is public or personal. Imagine how it would be if those who should do important tasks failed to be on time. A man who is known to be often unpunctual is never believed by his friends.The Chinese meaning of the word "punctual" in this passage is probably “________”.

| A．in a hurry | B．after the host | C．at the decided time | D．before other guests |

| Dear Mr. Wise, I’m a slow student. Most of my classmates are much better than me, so I usually get stressed out. Although I spend much time studying for the tests, I can’t get good grades. Sometimes my father gives me some help. He tells me not to worry about it, but it doesn’t work. What do you think I should do? Li Lei |

| Dear Li Lei, Many famous people were not so good when they were young. Edison, a famous scientist, did poorly in his studies when he was a young boy. But, as an adult, he made many inventions that helped a lot of people. When I was at young age, I didn’t do well at school. I just kept working hard, and at last, I succeed.

Healthy eating doesn’t just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others’ healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. After you don’t eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast.
Eat healthy snacks like fruits, yogurt or cheese. We all need snacks sometimes. In fact, it’s a good idea to eat two healthy snacks between your three meals .This doesn’t mean that you can eat a bag of chips instead of a meal.
Don’t eat dinner late. With our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest（消化） most of the food before you rest for the next 8—10 hours. How many pieces of advice does the writer give us?
What snacks are mentioned in the passage?
Should we keep eating until we are full?
