Ben and his wife Susan were on their way to have dinner with their friends. It was a dark，windy night, and they did not know the way very well. They drove through a town until they found what they thought was the road to Dorling，where their friends lived. But it soon became clear that they were not on the road to Dorling at all.

Everyone has got two personalities(性格)—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control your behavior(行为), but when you're asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you sleep in.
If you go to sleep on your back , you’re a very open person . You normally trust people and you are easily influenced by fashion or new ideas . You don’t like to upset people , so you never express your real feelings . You are quite shy and you aren’t very confident .
If you sleep on your stomach, you are a rather secretive (不坦率的) person. You worry a lot and you're always easily upset. You're very stubborn(顽固), but you aren't very ambitious(抱负的). You usually live for today not for tomorrow. This means that you enjoy having a good time.
If you sleep curled up (卷曲), you are probably a very nervous person. You have a low opinion of yourself and so you're often defensive (防御性的). You're shy and you don't normally like meeting people. You prefer to be on your own. You're easily hurt.
If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You're usually careful. You have a confident personality. You sometimes feel anxious, but you don't often get depressed. You always say what you think even if it annoys people.Point out which sentence is used to show the personality of a person who is used to sleeping on his or her stomach?
| A．He or she is careful not to make others angry. |
| B．He or she doesn't want to stick to his or her opinion. |
| C．He or she can't be successful in any business. |
| D．He or she likes to bring others happiness. |
Maybe you don't want to make friends with a person who sleeps curled up. Why?
| A．He or she would rather be alone than communicate with you. |
| B．He or she is rarely ready to help you. |
| C．He or she prefers going out to staying at home. |
| D．He or she wouldn't like to get help from you. |

| B．he or she is confident, but not stubborn |
| C．he or she has more strengths than weaknesses |

An 80-year-old man was sitting on the sofa in his house along with his 45-year-old son. Suddenly a crow (乌鸦) landed on their window.
The father asked his son, “What is that?”
The son replied, “That is a crow.”
After a few minutes, the father asked his son for the second time, “What is this?”
The son said, “Father, I told you just now. It’s a crow.”
After a little while, the father asked his son the same question for the third time, “What is this?”
This time, the son said to his father in a low and cold tone, “It’s a crow, a crow.”
After a moment, the father yet again asked his son for the fourth time, “What is this?”
This time his son shouted at his father, “Why do you keep asking me the same question again and again? I have told you already, ‘ITIS A CROW’. Are you not able to understand this?”
A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page.
Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn’t at all feel angry, but instead felt affection for my son.
If your parents reach old age, do not look at them as a burden（负担）, but speak to them gently, and be kind to them. From today say this aloud, “I want to see my parents happy forever. They have cared for me ever since I was a little child. They have always showered me with love. I will take care of my old parents in the best way no matter how they behave.”The old man brought out the diary, which he had kept since his son was born, because ______.

The writer mainly intends to ______ .
| A．tell us the function (作用) of a diary | B．call on us to love our parents |
