Need help ASAP

Liang was standing in the hallway when she saw her younger brother, Bao, coming out of the earth science classroom. He didn’t see her at first, and when he did, he looked embarrassed that she knew that he had stayed late to get extra help. Although they rarely talked about it, Liang knew Bao was having trouble understanding earth science, and the final was in a few days. Liang also knew how much it meant to him to do well on the test, but science was difficult for Bao.

3. Liang thought about her brother a lot. He was good at English and especially at writing. He loved to write stories about things that were happening and then have them printed in the school newspaper. He was the youngest person on the newspaper staff, and that was quite an honor. No one was sure why Bao was so talented in English—certainly, his mother and father had no idea—but for as long as he could remember, he wanted to be a journalist. He hoped someday to be a foreign correspondent, traveling to faraway places and covering exciting stories. Liang remembered Bao as a child frequently reading and writing things, even before she was interested in doing so.

But now, Liang was worried about Bao and how he was doing in earth science. She had never had a problem with any kind of science course. She excelled at chemistry, which she was taking this term, and hoped one day to be a science teacher. She was three years older than Bao, and she felt much more secure than he did because she had more experience. She had had her problems in school but worked hard and mastered difficult subjects like English. While writing was second nature to Bao, Liang had to work hard at it, but she was able, through revising and revising, to create a thoughtful and sound paper when she needed to do so.


1. Bao found Liang in the kitchen, reading a book. He turned to her and said, “I think your paper is very good, but if you made an outline of what you want to say, and then make some other little changes, it would be even better.” Bao started to bubble over with other kinds of suggestions, and then he stopped and looked more closely at what Liang was reading. “I’ve always loved earth science,” Liang said to Bao. “I just wanted to review some of the material—I’ve forgotten a lot since I took it in my freshman year, and if I want to be a science teacher, I should keep reviewing all aspects of science.”


Bao smiled to himself as he began to realize what Liang was trying to do. His sister’s motives were a bit transparent, but he thought, if she wants to help me that much, I guess I should let her.

5. “Would you mind if I reviewed the material with you too? I’m a little confused about some of the things that we are required to know,” he asked his sister, who smiled and nodded yes.

9. Several days later, the final exam was over, and Bao was pleased with his grade. He went to his sister and thanked her. “You went to a lot of trouble for me. Thanks. It means a lot,” he told her.
