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(掃描) made it clear: Andrew had a malignant brain tumor(惡性腦腫瘤) . 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(旁聽) 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.

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’(外來務(wù)工人員的)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.
But there is a long way to go. The free schools for children from migrant workers’ families are not enough because to run such a school is not easy and needs lots of money. A school officer said they needed at least one million yuan to run the school. “Luckily, some people and companies donate(捐贈(zèng))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(和諧的).
小題1:From the passage, we know that Li Xin’s parents used to be __________.
A.workersB.teachers
C.officersD.farmers
小題2:The school provides Li Xin with the following things free except_____.
A.textbooksB.uniforms
C.computersD.meals
小題3:What does the underlined word “run” mean in Chinese in the passage?

小題4:The passage mainly talks about__________.
A.what jobs migrant workers can do in big cities
B.the development of big cities
C.helping migrant workers’ children go to school
D.what difficulties those free schools face now

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(珍貴的)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(無價(jià)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.

Very few people enjoy exams. I don’t, either. And although I tell myself not to worry about them, I always do! So I’m not surprised that my students worry about them, too, even though they usually don’t need to. Because they are afraid of failing. However, since it is hard not to worry at all, we all must try not to worry too much. Why? Because worrying makes exams worse! How to do this?
Ask the teacher about how to revise and about exam skills—how to work when you are in the exam. Good students don’t wait until the week before an exam. They study all through the year. It is not possible to learn everything at the last minute. So don’t leave it till then.
If you start planning and working for each exam early and you make sure that you understand what you’re studying, then, when it is over, you’ll be able to say, “What a good exam that was!”
Take a short rest during your time of work and revision. If your mind is tired, it won’t remember well. Work at the time when you know you’ll work at your best.
If you’re studying in the evening, don’t go straight to bed afterwards. Your mind will still be “going round and round”—thinking too much. Do something else, maybe walk or get exercise. Choose something that will relax you, and make you think of other things.
If you feel bad, talk to someone about your worries. But don’t be too relaxed! Some stress over exams makes you work hard for them.
小題1:How does the writer feel about exams?
A.Excited.B.Bored.C.Worried.D.Surprised.
小題2:Why are the students afraid of exams?
A.Because they are afraid of failing.
B.Because they want to get full marks.
C.Because exams are usually hard.
D.Because their teachers will be angry at their bad grades.
小題3:Which is NOT mentioned in the passage?
A.Good students don’t wait until the week before an exam.
B.Start planning and working for each exam early.
C.If you don’t know how to work for an exam, ask the teacher about it.
D.You should sleep well before the exam.
小題4:According to the passage, if you feel bad, you’d better _____.
A.take a short rest
B.tell someone about your worries
C.walk or get exercise
D.keep busy working and forget your worries
