Everybody makes decisions in daily life. They can be as important as what you will do in the future or as simple as what you will eat for breakfast. Any decision could be the turning point of your life.

I made an important decision when I was in Junior 3.

Before I made that decision I wasn't a good student. I didn't listen to my parents or teachers, and my grades became poor. Then came the high school entrance exam.

At the turning point of my life, my mom wanted to have a conversation with me. I felt impatient but when I looked at her eyes, I felt I couldn't refuse. Instead of asking me to study hard, to my surprise, Mom just asked what I wanted to do in the future. Without thinking too much, I just said I would like to study hard.

Mom smiled and asked again, "I asked: what do you WANT to do?"

I had never seriously thought about the question before. So, I kept silent.

"Whether you want to go on studying or enter the society," she went on, "it is your own decision. It should be made by yourself, not anyone else, including me." After saying that, she had tears in her eyes.

For the first time in my life I was asked to make my own decision. I sat in my chair and thought about my life, my future and what kind of person I wanted to become.

It took me what seemed to be ages to make the biggest decision so far in my life—I wanted to be a man who makes a difference in the world. To achieve that, I needed to study hard.

The path to my future became clear to me. I didn't act rebelliously (叛逆地) any more. With passion (激情) in my heart, I studied hard.

Now, I'm 17 and I'm in one of the best schools in my city, in one of the best classes at the school and I am one of the best students in the class.

Thanks to that decision, I have become what I am today.

    A . After he was 17 years old. B . After he was in one of the best classes. C . When he was a pupil. D . When he was studying in Junior 3.

  3. (3) How did the writer make the decision?
    A . It was easy for him to make the decision. B . It was his second time to make the decision. C . He made the decision seriously. D . it was his mother that made the decision for him.
  4. (4) Why did the writer make the decision?
    A . Because his teacher talked with him patiently. B . Because he didn't want to act rebelliously any more. C . Because his mother asked him to study hard as usual. D . Because his mother asked him to think about his future by himself.
  5. (5) Which of the following is TRUE?
    A . The writer himself made the decision that he should work hard. B . It took the writer several years to make the decision. C . After hearing his mother's words, the writer had tears in his eyes. D . At the turning point of his life, the writer wanted to have a talk with his mother.
