Suraya talked about her plans in an interview.Q: What caused you to want to help these children?A: I went to Africa a couple of years ago, and my sister and I volunteered at an orphanage in Uganda. Most of the children I worked with were 10 and 11. The orphans were really talented and really bright. I just saw the need. I liked the idea that anyone like me could help.Q: What made you think of using your gaming apps?A: I taught myself how to program a few years ago. The apps are great. But I didn’t want them to just sit on the App Storeas stupid games. And then I thought of connecting each one to a kid at the orphanage I worked at. So that’s how it started.Q: Do you make money by having people pay to download them?A: A couple of them must be paid for but the rest are free with advertisements. The first ones were free, because I wanted to get things rolling. But I’m pretty sure from now on I’ll have all of them paid for, because it’s the best way to grow successfully.Q: How do you see Rizikitoto developing?A: I can see it being pretty big. I want other kids to program apps for the company, so it won’t be just myself. I’m trying to reach out to other groups, too. And I’d like to work on more projects like this.1. What’s the best title for the text?A. Give Kids a HandB. Make Money from AppsC. Apps for African OrphansD. A Special African Teenage Girl2. Suraya came up with the idea of helping African orphans______.A. because of her trip to UgandaB. under the influence of her sisterC. together with other volunteers in AfricaD. after she saw the hardship at an orphanage3. The underlined part“get things rolling”probably means “______”.A. make an early startB. make an experimentC. make things begin smoothlyD. make things easy and simple4. What does Suraya think of the future of Rizikitoto?A. Worrying.B. Uncertain.C. Challenging.D. Bright.三、读后续写阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
