Dear Dr Jackson, 
My parents are never happy with me. They are always criticizing (批评) my clothes, my hair and the music I listen to. They hate my friends' looks and they keep complaining when I go with them. I'm not allowed to stay out as late as my friends do, so I can't have any fun, My parents only seem to care about my school marks. Although I love them, sometimes I feel we live in different worlds. If they love me, can't they understand me? How can I make them understand me? 
Dear Angel,
Your problem is common (共同的) to both teenagers and parents. Don't worry, bacause all this is natural.You see, your parents have grown up at a different time and they have different experiences. So, they think some things are strange, but you find the same things ordinary. For example, the music you like may sound like noise to them. Your parents love you, so they feel they must protect you from whatever they find strange.On the other hand, you don't want to be different from other teenagers, so you feel that your parents restrict you. 
I think you should talk about this problem with your parents. Try to explain to them what you want and make them know they can believe you. Sooner or later. they'll find you are a responsible (有责任心的) person and they will give you more freedom (自由).
【小题1】Why has Angel written to Dr Jackson?

"Tammy! Come here, please! Mother needs your help in the kitchen." Her father called out to her.
Tammy was in her room, getting ready to do her homework. "Yes, Daddy!" she replied. "I'll be right there."
She hurried out of her bedroom and down the hallway. She was only nine years old. Her elder sister, Ella, had just moved away to go to a performing arts high school in another city. Her brother, Harry, was in middle school and always got home late. With Ella leaving home, Tammy was expected to do a lot more than she had ever done before, especially now, because her mother was ill.
Her father was in the kitchen. "Tammy, I know you usually do your homework right now, but with things being different, we all have to change a little bit. I'll help you and Harry with your homework later on, OK?"
Her father had an apron（围裙） on over his clothes, and he looked kind of funny. He was doing the dishes and he always splashed（溅出） water all over when he did that. After helping her father with the dishes, Tammy helped set the table.
After supper, her father helped her and Harry with their homework, and then they played a board game so that their mother could lie down for a while.
The next morning, Tammy got up early on her own because she wanted to help her mother with breakfast. She made orange juice and even put bread in the toaster and got out the butter so that her mother could sleep for a few more minutes.
When her mother got up half an hour later, she was very surprised and moved to see the breakfast on the dining table. She gave Tammy a big hug.
"Thank you, Tammy. You really are mother's little helper now, aren't you?"
