Tom likes chocolates very much, but his mother doesn’t give him chocolates, because they’re bad for his teeth, she thinks. But Tom has a very nice grandfather. The old man loves his grandson very much and sometimes he buys Tom some chocolates. Then his mother lets him eat them, because she wants to make the old man happy.

On Sunday evening, it is Tom’s birthday. He says,“Please, God(上帝), let them give me a big box of chocolates for my birthday.”His mother says,“God can’t hear you. Don’t shout.”“I know,”says the clever boy with a smile.“But Grandfather is in the next room, and he can.”

One way that scientists (科学家) learn about man is by studying animals．In this lab, the scientists are studying the relationship between diet and health．

They are studying the relationship between the amount (数量) of food the mice eat and their health．The mice are in three groups．All three groups are receiving the same healthy food．The first group is eating one cup of food each day, the second group is eating two cups, and the third group is eating three cups．

After three years, the healthiest group is the one that is only eating one cup of food each day．The mice in this group are a little thinner. But they are more active．Most of the day, they are running, playing with one another．Also, they are living longer．Mice usually live for two years．Most of the mice in this group are still alive after three years．

The second group of mice is healthy, too．They are active, but not as active as the thinner mice．They are only living about two years．

The last group of mice is receiving more food than the other two groups．Most of the day, these mice are eating or sleeping．They are not very active．These mice are living longer than the scientists thought－about a year and a half．But they are not healthy．They are sick more often than the other two groups．

If someone asks me, “Do you like music?” I will answer him or her, “Of course, I do.” Because I think music is an important part (部分) of our lives.

Different people have different ideas about music. For me, I like rock music (摇滚乐) because it’s so exciting. And my favourite rock band (乐队) is Foxy Ladies (酷妹). I also like pop music. My classmate Li Lan loves dance music, because she enjoys dancing. My best friend Jane likes jazz music (爵士乐). She thinks it is really cool.

“I love dance and rock music very much,” says my brother, “because they are interesting.”

But my mother thinks rock is boring. “I like some relaxing (轻松的) music,” she says. That’s why she likes country music, I think.

Dear friends, do you like music? What kind of music do you like?
