Dear Alice,
I just received your letter. And I was very surprised to know that you decided to drop out of school and wanted to be a model （模特）.
Being a model for a living is not easy. In fact, a famous person like me has a lot of problems that you couldn't see. I can't eat what I like, even though I'm very hungry. Keeping thin makes me look more beautiful on the stage because no one would like to see a heavy model.
Besides, I have to wear a heavy coat in the hot sun, in a swimming suit in the cold air. And practicing walking nicely every day is tiring for me.
You might say I made much money from modeling. But my dear niece （侄女）, you have to know that money is, nothing, knowledge is everything. School is important and everyone should go to school for a certain period of time. The longer they stay at school, the better they will be. Very often, I hope I can give up my job and continue my studies at school. But it is very difficult for me to go back to school again. I am too old to go back to school now.
You are a pretty young girl with a bright future. You only have one year to finish your studies in high school. A year is really short. Please do consider my words carefully before you decide. Of course, there is only one thing I care about, and that is your happiness.
Love,
Emma

    One day, the Earth was very sick. He felt so bad that an earthquake happened. After the earthquake, it rained every day. Then the Sun told him to go to the hospital.

    The Moon looked at the Earth and said, "Look! Your skin should be the blue sea and the green land, but it is turning more and more yellow… "

    "It is the desert," the Earth said.

    The Moon put on her glasses and looked at him carefully. She saw that some people were cutting down trees near the desert.

    "I'll make these trees into chairs and beds. I'm going to get married in a few days," a young man said happily.

    "I want to make a wonderful piece of art with this tree," an artist with long hair said.

    "I'm too poor and I have a big family. I need to sell these trees to make money," an old man said while cutting down the small trees.

    "Winter is coming! I need more wood to make my house warmer," an old woman said.

    At that moment, a truck came with giant machines. A group of men got off the truck.  They began to cut down the trees with the machines quickly. Soon, all the trees disappeared and the truck took them away.

    The Earth began to cry. The Moon was too surprised to do anything. The desert laughed at the Earth, "Ha! Ha! You have nothing to do with me!"

    Most musicians agree that the best violins were first made in Cremona, Italy, about 200 years ago. These violins sound better than any other violin. They even sound better than the violins made today. Violin makers and scientists try to make instruments like the Italian violins. But they aren't the same. Musicians still prefer the old ones.

    Some people think it is the age of the violins. But not all the old violins sound wonderful. Only the old violins from Cremona are special. So age cannot be the correct answer.

    Other people think the secret to those violins is wood. The wood must be from certain kinds of trees. But the kind of wood may not be so important. It may be more important to cut the wood in a special way. Wood for a violin must be cut very carefully. It has to be the right size and shape. The smallest difference will change the sound of the violin.  Musicians sometimes think that it is the secret of the Italians. Possibly they understood more than us about how to cut the wood.

    Size and shape may not be the answer either. Scientists can make new ones which are exactly the same size and shape. But the new violins still do not sound as good as the old ones. Some scientists think the secret may be the varnish (清漆). Varnish is what covers the wood of the violin. It makes the wood look shiny. It also helps the sound of the instrument. But no one knows what the Italian violin makers used in their varnish.

    "Doctor Johnson, I don't want to eat now, that's because nothing has a taste for me. It's been like this for long. In fact, I didn't have a delicious meal after I caught a terrible cold last month, What can I do?"

    "Here are some medicine, Mrs. Harris. Take three pills three times a day for seven days and come back and see me. But remember, don't eat anything during the week, or you can just drink some water."

    Next week an upset Mrs. Harris came into Dr. Johnson's office. "Doctor! I'm doing it just as you told me, but delicious food is still tasteless for me. I don't know what was in those pills, but the problem is worse! What do you have to say for yourself?"

    "But when and how do you take these pills?" asked the doctor.

    "At first, I took these pills three times a day, just before dinner," continued the woman, "but these pills are too bitter (苦). So I had to take these pills after three meals."

    "Calm down, Mrs. Harris," said the doctor soothingly. "Now that we've fixed your taste problem, It's OK now, we'll work on your hearing!"
