【題目】This 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(遙控潛水器), 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(探測(cè)) system. She uses a camera along with three different kinds of light to find the plastics. She also uses visible(可見(jiàn)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(氣候) 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, 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.”

【1】What did Anna Du notice while walking along the beach?

【2】How old was Du when she did a little research to solve the problem?

【3】What can Du’s ROV do?

【4】Why does Du want to be an engineer in the future?

【5】What made Du succeed in building her ROV?

Answer 1

【答案】

【1】She noticed plastics.

【2】At the age of 12. / When she was 12 years old.

【3】It can move through water and find plastics on the ocean floor.

【4】Because she likes building things to help solve world problems.

【5】Her good engineering sense to break down a problem, the engineering skills necessary to build it, her persistence(not giving up) and her parents' support.（另外答出the careful observation, the awareness of protecting the oceans也可酌情給分）

【解析】

文章大意：本文主要講Anna Du十二歲時(shí)就制作了自己的遙控潛水器，她從小就對(duì)STEM感興趣，長(zhǎng)大后想成為一名工程師，幫助解決世界問(wèn)題。

【1】

根據(jù)第1段中“Anna Du was walking along the beach when she noticed plastics there.”可知Anna Du在海灘散步的時(shí)候注意到了塑料。故答案為：She noticed plastics.

【2】

根據(jù)第2段中“Du, 12 years old at the time, tried to solve the problem like any good scientist—first, by doing a little research.”可知Du做了一點(diǎn)調(diào)查來(lái)解決這個(gè)問(wèn)題的時(shí)候，她12歲了。故答案為：At the age of 12. / When she was 12 years old.

【3】

根據(jù)第3段中“Her ROV can move through water and find plastics on the ocean floor.”可知Du的ROV能夠在水中移動(dòng)，找到海底的塑料。故答案為：It can move through water and find plastics on the ocean floor.

【4】

根據(jù)最后一段中Du的話“I know I want to be an engineer because I like building things to help solve world problems”可知她想要成為一名工程師是因?yàn)樗�喜歡制造東西來(lái)幫助解決世界問(wèn)題。故答案為：Because she likes building things to help solve world problems.

【5】

根據(jù)第5段中“She has a very good engineering sense to break down a problem like this and then go after it”可知她在解決問(wèn)題方面有良好工程悟性；根據(jù)第6段中“and so she picked up the engineering skills necessary to build her ROV”可知她學(xué)會(huì)了建造ROV所需的工程技術(shù)；根據(jù)第6段中“She failed many times, but she never gave up trying and testing.”可知她不輕言放棄；根據(jù)倒數(shù)第2段中“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).”可知Du的父母很支持她。這幾點(diǎn)都是她成功制作ROV的重要因素。故答案為：Her good engineering sense to break down a problem, the engineering skills necessary to build it, her persistence(not giving up) and her parents' support.（另外答出the careful observation, the awareness of protecting the oceans也可酌情給分）
