A teacher asks his students to write about their dreams. One boy writes seven pages. He wants his own farm and a large house on it. But his teacher tells him, "You are daydreaming. Do it again." Several days later the boy hands in the same article, saying, "I don't want to give up my dream even if you fail me." Years later, he makes his dream come true. One day, the same teacher takes some students to the boy's farm for camping. Seeing the big farm, the teacher feels sorry, "I once told you not to daydream. Luckily, you never gave up."

Here is some information about two zoos in a city. Let's have a look!

Mobile phones have become a problem for middle schools.The Education Department of China has announced that schools should ban （禁止） students from carrying mobile phones during school hours.

Mobile phone use among children has become a problem.Several children have got mobile phones from parents and relatives as gifts，and more students will want them.

An expert said mobile phone use was a distraction（分心的事） to students during school hours.Teachers were also saying that sometimes students might use phones to chat or play game in class.Some students could use them to cheat during exams.

The expert said some schools had tried to ban mobile phones.Some parents felt unhappy because they couldn't call up their children.

Many teachers said students should not have mobile phones at school，but if there was a good reason，they could leave their phones at school office.

Many people say that they understand why parents would want their children to have phones，but they think schools should let the students know when they can use theirs mobile phones.

The mobile phone is a double—edged sword（双刃剑）for teenagers.How to solve the problem reasonably？It's well worth considering.

Bob and Ken are best friends，and both of them are sports lovers. One day after class，Bob asks Ken to play volleyball together. While playing，Ken runs so fast that he falls to the ground. "My arm!" he cries. When Bob comes to help Ken stand up，he sees that it is broken （受伤的）. 

Bob runs to call Ken's parents. After that，Ken's parents take him to the hospital. In the hospital，the doctor checks （检查） his arm and tells Ken that he needs to take care of his arm. He also asks Ken not to play sports during the next 35 days. 

The next day，Ken goes to school and tells the class his story. They have many questions，and Ken answers them one by one. But Bob is quiet，and he keeps drawing something on the paper. Ken walks to Bob，smiles and says， "Bob，        ▲        . " 

At that time，Bob looks into Ken's eyes and asks， "Do you want to play tic-tac-toe today？We can't play sports today. " "Great idea!" Ken answers. What good friends!
