练习册系列答案

Andrew Engel was puzzled. He was sitting in class, but had no idea what the other students were talking about. He had done his homework, paid attention to lectures, and taken notes, but nothing was familiar. “Everyone is so much cleverer than I am,” he thought. It was a strange feeling, as he was always a good student in high school.
He felt even more puzzled a few days later. He got lost on his way to his favorite cinema. What’s worse, he began having trouble finding the right words when speaking. He asked, “What’s for dinner, Mom?” after he had just eaten. Poor Andrew, he was only 15!
His parents were worried and took Andrew to see a doctor. A brain scan（扫描） made it clear: Andrew had a malignant brain tumor(恶性脑肿瘤) . It was pressing on the part of the brain that makes new memory. He should be operated on as soon as possible. Andrew was scared!

“Even though they told me this, I knew I wanted to go back to school,” Andrew said. “I wanted to get my memory back.”

With more and more farmers working in big cities, their children go into the cities, too.However, problems appear. One of these problems is that is difficult for these children to receive education in cities.
Luckily, there are some free schools for them, but they are not enough. Ten-year-old Li Xin is one of the lucky girls who get a chance to study in one of these schools. She is very happy. She studies in a school specially for migrant workers’（外来务工人员的）children. For children like Li Xin who don’t have enough money, these free schools are their best choice, because they have free classes, textbooks, uniforms and meals in the schools.

A school officer said they needed at least one million yuan to run the school. “Luckily, some people and companies donate（捐赠）money, used books and a lot of other things to help us. There are also some volunteers teachers,” he added.
Anyhow, we must try to give these children an equal（平等）chance to get better education so that we can make our society harmonious（和谐的）.

Future and Today
　　It is well known that everyone has his own dream as well as his own future. But do you know what future really is ? I have to say that future is now. That is to say we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
　　There is an old English saying: "Gain time, gain life." Then what's time? Time is something that we can't see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say "Time is money", but time is even more precious(珍贵的)than money, because when money is spent , we can earn it back. But if time is gone away, it will never return. So, some of us even say time is priceless(无价的).
　　We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off what can be done today till tomorrow.
　　As we all know , "Time and tide wait for no man." If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter .Remember: "No pains, no gains." Today's hard work is the cause of tomorrow's harvest.
