原文
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 i( ) 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 r( 2 ). She conducted surveys and searched for information. 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） ﹣﹣ 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 c( 3 ) amera along with three different kinds of light to find the plastics through pictures. 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 s( 4 )， but it's a level of thinking that's really difficult."
Do 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 f（5） many times， but she never gave up trying and testing.
When asked about future plans， she said that she wanted to address the effects of climate （气候） change. "I think there are a lot of problems that could be solved with new i（6）." says Du.
Du thanks her parents， who for years have taken her to student outreach activities， 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."
L（ 7 )， she has plenty of time to figure that out at her age.
文章大意
本文讲述了年轻科学家Anna Du发现海洋塑料污染问题，并发明遥控潜水器（ROV）来解决的故事。她从海滩上的塑料碎片出发，通过调研和搜寻信息，认识到每年有数百万吨塑料流入海洋。她设计的ROV能够探测海底塑料，利用不同光线和相机拍照定位。Du从小培养工程技能，坚持不懈地试验和改进ROV。她表示希望用新发明解决气候变化等问题，并感谢父母对她STEM领域的支持。她梦想成为工程师，为世界问题贡献自己的力量。
解析
1 It seemed i( impossible ) to clean them all up.
翻译
似乎要清理完所有这些塑料碎片是不可能的
分析
根据句子分析，此处缺形容词
上一句说碎片太多，她无法收集完，因此清理完看起来是不可能的，所以填 impossible (不可能的)
2 Du,12 years old at the time,tried to solve the problem like any good scientist-first,by doing a little r( research ).
翻译
当时年仅12岁的杜像所有优秀的科学家一样，首先通过进行一些研究来尝试解决这个问题。
分析
根据句子分析，此处缺名词
科学家解决问题，要研究、调查 ，因此填 research (研究、调查)
3 She uses a c( camera ) along with three different kinds of light to find the plastics through pictures.
翻译
她使用相机配合三种不同的光线，通过图片来寻找塑料。
分析
根据句子分析，此处缺名词
根据上下文通过图片来找塑料，图片是拍出来的，因此填 camera (相机)
4 It sounds s( simple ),but it's a level of thinking that's really difficult.
翻译
这听起来很简单，但这是一种真正难以达到的思维水平
分析
根据句子分析，此处缺形容词
听起来简单，做起来难，后面表述是一种难以达到的水平，因此前面填 simple (简单的)
5 She f( failed ) many times， but she never gave up trying and testing.
翻译
她失败了很多次，但她从未放弃尝试和测试。
分析
根据句子分析，此处缺形容词
后面说从未放弃尝试和测试，说明前面失败了很多次了，过去发生的，因此用过去式所以填 failed (失败)
6 I think there are a lot of problems that could be solved with new i（ideas/ inventions）.
翻译
我认为有很多问题可以通过新的想法/发明来解决
分析
根据句子分析，此处缺名词
很多科学问题的解决，需要有新想法，创新，因此填ideas(想法)/ inventions(发明)
7 L（ Luckily )， she has plenty of time to figure that out at her age.
翻译
幸运的是，她这个年纪有很多时间去弄清楚这个问题
分析
句首一般放置副词Luckily。它可以用来修饰整个句子或句子的某一部分，表达一种侥幸或幸运的语气
这么多问题，她有很多时间去弄清楚，说明是幸运的
