閱讀短文，根據(jù)短文內(nèi)容回答問(wèn)題。

Steven is in the ninth grade now. He likes doing projects at school. Two years ago，he made a digital programme for the traffic system. After getting the prize, he got the advice from his father: “Do what interests you, and make sure you put your heart into it.”

Steven always prefers the projects which connect to our real life! He still remembers the project he has done. First of all, he tried to divide the whole project into several small parts. He usually gave himself some basic ideas after thinking them over and over again. When he met with some problems that he couldn’t work out by himself, he used to go to the teachers’ office and ask his teachers for help. At the beginning of his research such a question “How do I do it?” often came to his mind. As he kept on studying and discussing with his teachers, those “how” questions soon turned into another type: “What if I do this and that way?”

It took Steven more than four days to write the code(編碼) on his computer. The desire(愿望) to solve the problems made him not get to sleep all nights. When he found his project going well, he jumped with joy. The last day of his work got deeply impressed(印象) in his mind. He went into trouble and didn’t know what to do next. At the moment, he noticed a man with headphones dancing while he was cleaning the room. This encouraged him to work on his project. He made good success at last.

Now Steven feels very proud of his projects and tries to do more projects at school.

1. Is Steven at school?

2. Who gave him the advice?

3. How did he begin to do the project?

4. What did Steven do when he got into trouble?

5. What can we learn from Steven according to the passage?
