I’m very glad to have received the letter you sent me two weeks before. I have been thought about the question raised in your letter. In my opinion, you should go back after you finish your studies at abroad. For one thing, that you are studying is badly needed nowadays in our country. It will be quite easily for you to find a good job. In fact, I know that a few big company in our city hope to hire people like you. For another, I think it will be more convenient for you look after your parents because they are getting older and older. And this is only my point of view. It is up to me to make a right choice.

Imagine looking for your lost dog. You step into a cave（洞穴）. But instead of the dog, you find beautiful cave paintings. You see paintings of horses, deer, and bison that are drawn in black, brown, red and yellow. Your first question would probably be "Who did this?"
This is what happened to four French boys in 1940. They found the Lascaux caves. The paintings the boys discovered in those caves are 17,000 years old. They were drawn by the ancient people called Cro-Magnons.
Cro-Magnons looked much like people of today. They used tools, such as fishing nets. But their art was extremely good. The main cave at Lascaux is called the Great Hall of Bulls, which has a picture of bulls and horses in many colors. The largest animal is 18 feet long. There are smaller animals, such as bison, stags（雄鹿） and a bear. There is also a strange spotted two-horned (两只角的) animal.
To the left of the main cave are the most famous paintings that are the drawings of multicolored animals. One painting is called Little Horses. On the ceiling are horses and cows. The most unusual sight may be in the Shaft of the Dead Man where there is a thinoceros (犀牛), a carefully drawn dead man, a wounded bison and a bird.
