山东省德州市宁津县2020-2021学年九年级下学期英语第一次模拟试卷
A 12-year-old Girl Built a Robot to Find Plastics in the Ocean
Anna Du was walking along the beach when she noticed plastics there. She reached down to pick them up, and quickly realized there were many more tiny pieces than she could deal with. It seemed impossible to clean them all up.
Du, 12 years old at the time, tried to solve the problem like any good scientist—first, by doing a little research. That's how she learned that 8 million tons of plastics end up in the oceans every year.
Then she got to work building something that could help solve the problem, a remote-operated vehicle(遥控潜水器), or ROV. Her ROV can move through water and find plastics on the ocean floor.
The actually cool part of Du's ROV is the detection(探测) system. She uses a camera along with three different kinds of light to find the plastics. She also uses visible(可见的) light to find unnatural colors that might make the plastics stand out.
"She has a very good engineering sense to break down a problem like this and then go after it," says engineer Casey Machado. "It sounds simple, but it's a level of thinking that's really amazing."
Du started attending public events and workshops at a university when she was five years old, and so she picked up the engineering skills necessary to build her ROV. She says actually getting her ROV to move through water well was not easy. She failed many times, but she never gave up trying and testing.
When asked about future plans, she mentions wanting to address the effects of climate change. "I think there are a lot of problems that could be solved with new inventions," says Du.
Du thanks her parents, who for years have taken her to student outreach activities(学生拓展活动), for supporting her interest in science, technology, engineering and math (STEM). She says she has been able to meet students and scientists there.
"I know I want to be an engineer because I like building things to help solve world problems," says Du. "But I'm not sure what kind of engineer I want to be yet."
（You may use your own words. ）
(At least 2 pieces.)
A. It's good for you to do some sports. You can play basketball with your classmates after school. B. Practice makes perfect. Try to have more practice in you free time. You can also ask your music teacher for some advice. C. Listening to English songs and watching English films are good ways to learn English. If you are interested in English, you can learn better. D. Why not have a talk with him after class? You can also ask him to help you with your math. If there is anything you can't understand, ask him and work it out. E. There are different kinds of activities in the city library every Sunday. People of all ages are welcomed. Why not go there and have an interesting weekend? F. I think you can talk with her. She is worried that you may spend too much time on them. It may be a good idea to play computer games once or twice a week, and only after you finish your homework. |
