举一反三
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!
Doctors removed the tumor, but Andrew’s memory was still poor. He was told he would probably never go back to school. Andrew was eager to enter a university, but it seemed that his dream wouldn’t come true.
“Even though they told me this, I knew I wanted to go back to school,” Andrew said. “I wanted to get my memory back.”
Andrew began by auditing(旁听) an English class at a nearby school. In class, he took notes carefully and read his notes several times a day, then typed them again and again. He studied twelve hours a day, seven days a week. He worked ten times harder than other students. In 2007, at age 29, he graduated from a local university. Six months later, Andrew found a job.

As we all know, the environment around us is getting worse and worse. In some places we can’t see fish 1 in the river or trees on the hills. Some people even have no clean water to drink.
Recently, a new lifestyle called low carbon life is 2 every corner of our country. The meanings of low carbon are 3 energy and no waste. It is such an important project that I can’t wait 4 my ideas on how to promote it.
First，we should 5 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 6 the no-car day, neither students 7 teachers are allowed to drive to school. At the same time，just walk or run. Use our 8 and enjoy the fun.
Second, we had better not use plastic bags 9 . No one can stand the “white pollution”， 10 it is wise to use cloth bags which can 11 again and again.
12 ，one thing 13 we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn 14 the lights the moment we leave, use 15 sides of the paper, and reuse our textbooks and so on.
All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these：no-car days, no plastic bags, and no waste. Let’s do it now.
