单项选择题

Passage Two 
Questions 6 to 10 are based on the following passage. 
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're awake because you can control your behavior, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, you frequently change their positions. The important position is the one that you go to sleep. 
  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.   
If you sleep on your stomach, you are a rather secretive (深藏不露的) person. You worry a lot and you're always easily upset. You are very stubborn (顽固的), but you aren’t very ambitious. You usually live for today not for tomorrow. This means that you enjoy having a good time.    If you sleep curled up (蜷缩), you are probably a very nervous person. You have a low opinion of yourself, so you are very defensive. You're shy and you don't usually 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 depress. You always say what you think, even if it annoys people. 

What can be said about one’s personality according to the passage （）
