           well in my  exams. I feel unhappy.
( )2. I found that my mother read my dairy when I was out. I don't think anyone, even my parents,
           has the right to read  my diary. Now I feel hurt and sad.
(      )3. Sometimes I get angry easily and shout at my friends. That makes them think I'm not being
            friendly to them.

            I feel sad.

     he will not call you in that way any more.
C. You need to sit down and really talk to your mother about this. Don't get angry. Use calm, clear 
     words to explain. Tell them that you are old enough to have more privacy ( 隐私).
