A little girl, less than two, was pushing her stroller (婴儿车) across the road. It was Sunday morning and traffic was not heavy. I stopped my car at once and ran toward her. This little girl knew enough to run from a stranger. I tried to catch her in order that I could get her out of the road. Suddenly her father came running down a hill across the road from where I had parked my car. He ran right to her and caught her up, saying “bad girl” to her. I picked up the stroller and gave it to him. The father grabbed (抓住) the stroller and walked toward where he came from without a word. I went back and sat in my car for a few minutes with my son. My hands were shaking and tears were about to run out of my eyes. “Do you feel cold, Mom?” asked my son. I just shook my head. After this happened, I thought about how thankful I was. Even though the father didn’t say thank you, I feel that I did something good. Doing something for someone else is pleasing, even when it’s only a matter of being in the right place at the right time. I didn’t really “save” her, but I feel like it was important that I happened to be there. It is sad that I was the only one who stopped. It really made me a little disappointed that no one else stopped to help. 21.When the author saw the little girl, ________. A.the girl had lost her way B.she was driving to work in a hurry

2019学年第一学期高一9月月考英语试卷 第一部分:阅读理解 (共20小题,每小题2分,满分40分) A Letter One Dear Editor, After I finish my homework, I often go online and chat with my friends. Sometimes I play computer games. But my parents hate to see me playing games on the computer. Maybe they have heard too much news about how QQ and computer games harm children. Once I went to a net bar(网吧) to play games after school. But after that I told my parents that I was playing basketball at school. I said so because I didn't want to make them unhappy. I feel bad about it. However, I need to rest for a while by playing computer games after studying for a long time. I really want my parents to understand that. Do foreign parents do the same to their children? Please help me. Li Ping, Beijing Letter Two Dear Li Ping, I don't think it's strange for parents to keep their children away from anything bad. Foreign parents will do the same as your parents! They may not let their children watch TV for too long a time, or like your parents, they don't want their children to play computer games. Talk to your parents and be honest to them, I think. Tell them what you are doing and why you are doing so to make them understand you. It's never good to do things behind your parents. They aren't fools as you think sometimes! Our parents seem to know what is the best for us. Remember: to be honest is the best way. Good luck, Rebecca 1. From the passage we can learn that Li Ping often__________ . A. talks with his friends on the Internet
