专题07 语法填空--2023-2024学年九年级英语上学期期末备考 仁爱版 （2022上·山东济宁·九年级统考期末）阅读下面短文，在空白处填1个适当的单词或括号内单词的正确形式。 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 1 (many) tiny pieces than she could deal with. It seemed 2 (possible) to clean them all up. Du, 12 years old at the time, tried to solve the problem like any good scientist—first by 3 (do) 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 4 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 5 (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 6 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 7 (get) 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 (气候) change. “I think there are a lot of problems that could 8 (solve) with new inventions,” says Du. Du thanks her parents, who for years 9 (take) her to student outreach activities, for supporting her interest in science, technology, engineering and math (STEM). She says she has been able to 10 (meet) students and scientists there. “I know I want to be an engin
