【题目】阅读理解

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项。

Everyone has got two personalities—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 are awake because you can control your behavior,but when you are asleep,your sleeping position shows the real you. In a normal night,of course,people frequently change their positions. The important position is the one that you go to 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 displease people. So you never express your real feelings. You're quite shy and you aren't quite sure of yourself.

If you sleep on your stomach,you are a rather secretive person. You worry a lot and you're always easily upset. You always stick to your own opinions or judgment,but you don't raise your hope too much. You usually live for today not tomorrow. This means that you enjoy having a good time.

If you sleep curled up,you are probably a very nervous person. You have a low opinion of yourself and so you're often defensive(防卫的). 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 strength and weakness. You're usually careful. You trust yourself. You sometimes feel anxious,but you don't often get sad. You always say what you think een if it makes people rather angry.

1】According to the passage,a person,who is not willing to change his mind probably sleeps ________.

A.on his side B.on his back

C.curled up D.on his stomach

2】If a person prefers to sleep curled up rather than on his back,he maybe want to ________.
