Ⅴ.【文章大意】 本文是一篇说明文。文章主要阐述了目前全球都在发展环保节能的电动汽车,但是铅酸电池中的铅是危险的,铅中毒给人类健康、财富和幸福造成巨大损害,不仅造成死亡还带来极大的社会负担。
1.A　推理判断题。根据第二段内容可知,作者通过列出三轮车铅酸电池中铅的含量来说明目前所面临的铅污染问题。故选A。
2.D　细节理解题。根据第三段中“The numerous ways lead enters air, water, soil, and homes across the developing world—and the enormous damage it does to human health, wealth and welfare—cause one of the biggest environmental problems in the world yet receive little attention.”以及第四段中“On top of the shocking deaths, the social burden of lead poisoning is heavy, as is its contribution to global inequality—our research on the cognitive (认知的) effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.”可知,在发展中国家,铅以多种方式进入空气、水、土壤和家庭,对人类健康、财富和幸福造成了巨大损害,不仅造成死亡还带来极大的社会负担,使贫穷的社会更贫穷。故选D。
3.D　推理判断题。根据最后一段“But unlike many challenges faced by developing countries, lead poisoning is a problem that can be resolved through financial investment (财政投入). Better monitoring, research and rules can help protect children all over the world from the unpleasant effects of lead poisoning and reduce the massive global costs it brings.”可知,发展中国家可以通过财政投入,进行更好的监测、研究以及制定规则来解决铅污染和铅中毒问题;由此可知,发展中国家可以通过投入一定的努力和金钱解决铅中毒问题。故选D。
4.B　主旨大意题。根据第一段中“In the rich countries of the West, the electric vehicle revolution is well occurring. Climate-conscious consumers drive Teslas or Polestars for reasons of morality (道德) and fashion. Poorer countries are also experiencing a wave of the electrified trend.”以及第二段“Yet a glance under the hood (引擎盖) of these vehicles shows a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries (铅酸电池), containing almost 300 pounds of lead in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leaks into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable (高利润的) but deadly business.”及全文内容可知,全球都在发展电动汽车,但是铅酸电池中的铅是危险的;文章还阐述了铅中毒给社会和健康带来的极大危害;由此可知,文章主要讲述目前发展电动汽车带来的铅污染问题、世界上铅中毒的严峻形势及其给社会和人类健康带来的极大危害;B选项(全球的铅中毒问题)能够概括文章主旨,适合作为最佳标题。故选B。
Ⅵ.【文章大意】 本文是一篇说明文。文章主要介绍了在种植过程中避免食物浪费的建议。
1.C　根据上文“If you grow your own food, the last thing you want is to let your hard work go to waste.”可知,自己种植食物时不想要食物浪费,结合下文“It begins with the plants you choose, and goes right through to preservation (保存) of your harvests.”可知,从选择植物到保存食物是一个长期的过程,C项(防止菜园里的食物浪费是一个长期的过程。)符合语境,故选C。
2.D　上文“Waste is far more likely to happen if you are growing plants that are not suited to the climate, soil and growing conditions.”提到容易发生食物浪费的情况,结合下文“Make sure they do not just provide food today, but can also adapt to the changing climate.”可知,空处应是关于防止发生食物浪费的情况,D项(所以想想如何在你的菜园中创建好的系统。)符合语境,下文they指代选项中的systems。故选D。
3.E　上文“People may often have more seeds (种子) than they really need, particularly in small gardens. However, seeds are usually only viable (能存活的) for a certain length of time.”提到种子数量多且存活时间短的问题,结合下文“And you can also share skills and knowledge with each other.”中的关键提示also share可知,空处是关于分享多出的种子,E项(在家庭之间分享它们可以避免浪费它们的潜力。)符合语境,选项中的them指代上文的seeds,故选E。
4.G　根据本段内容“You might, for example, grow some strawberries inside a greenhouse, with others outdoors. Those grown under cover will typically be ready to harvest a little earlier. Or you can grow different varieties of plants.”可知,本段主要讲想办法让植物的收获时间不一样,通过这样的方式来避免浪费,G项(为某些作物安排不同的收获期可以帮助避免浪费。)符合语境,故选G。
5.F　根据本段首句“Once you have grown your crops, it is important to be ready to preserve what needs to be preserved.”以及空前“You can freeze, pickle (腌制) or process a wide range of garden produce.”可知,本段是说收获后要好好保存,空前提到了一些保存的方法,F项(当收获季节到来时,确保你知道如何正确地做到这一点。)符合语境,故选F。
Ⅶ.【文章大意】 本文是一篇说明文。文章主要介绍了地球日的由来。
1.was founded　考查动词时态、语态和主谓一致。句中主语Earth Day与动词found之间为被动关系,所以用被动语态。再根据句中时间状语in 1970可知用一般过去时,且主语是第三人称单数,故填was founded。
2.events　考查名词复数。名词event为可数名词,根据a full seven days of可知应用复数形式,表示“整整七天的活动”。故填events。
3.Elected　考查非谓语动词。elect与其逻辑主语Senator Gaylord Nelson之间为被动关系,所以用过去分词作状语。单词位于句首,首字母大写。故填Elected。
4.at　考查介词。短语at risk表示“处境危险,在危险中”。故填at。
5.being inspired　考查非谓语动词。介词after之后用v.-ing形式。主语Nelson与inspire之间为被动关系,所以用动名词的被动形式。故填being inspired。
6.who/that　考查定语从句。句中先行词为a young activist,指人,关系词在定语从句中作主语,所以用关系代词who或者that。故填who/that。
7.an　考查冠词。an army of表示“一大批,一大群”,army为元音音素开头,所以用不定冠词an。故填an。
8.to organize　考查非谓语动词。此处用不定式作目的状语。故填to organize。
9.awareness　考查名词。raising后接名词作宾语。故填awareness。
10.largest　考查形容词最高级。EarthDay.org 希望这将是历史上规模最大的志愿者活动。根据句意可知,此处用形容词最高级形式。故填largest。Unit 8　GREEN LIVING
　　The artist and architect Maya Lin became famous at a young age because she won a national competition to design a memorial honouring those serving the country. The memorial based on Lin’s design is one of the most popular and influential monuments in Washington, DC and is visited by three million people each year.
She was also famous for many other works, including the Civil Rights Memorial and the Riggio-Lynch Chapel. In 2016, the president presented Lin with the nation’s highest honour for her architecture, sculpture and landscape art.
Lin recently spoke at William Paterson University as part of the university’s well-known lecture series. She thought of herself more as an artist, making sculptures, who also happened to build buildings. She supposed good works must be full of art and it was the soul of architecture. At Yale, she decided that architecture would be a perfect combination of art and maths. Her formal training was in architecture. Lin earned a master’s degree in Architecture in 1986.
She felt close to nature and the environment when she was a child. When she was growing up, she was almost outdoors playing in the woods behind the house every day. The environmental movement also had a strong influence on her childhood. She’s always been focusing on nature, science and the environment in her works.
Her concern for the environment and the sad fact that one species is causing the extinction of so many other species, as well as the urgency of trying to solve climate change inspired her to start the “What is missing ” project. By protecting and restoring habitats, we could reduce fossil(化石) fuel emission(排放) and protect biodiversity(生物多样性) at the same time.
She showed us a new way of looking at the world. She believes that all of us, whether we choose to help other people or the planet, are all helping ourselves.

●Ⅴ 阅读理解
In the rich countries of the West, the electric vehicle revolution is well occurring. Climate-conscious consumers drive Teslas or Polestars for reasons of morality (道德) and fashion. Poorer countries are also experiencing a wave of the electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate-friendly, cost-effective, and help reduce air pollution.
Yet a glance under the hood (引擎盖) of these vehicles shows a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries (铅酸电池), containing almost 300 pounds of lead in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leaks into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable (高利润的) but deadly business.
Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an unexpected scale. The numerous ways lead enters air, water, soil, and homes across the developing world—and the enormous damage it does to human health, wealth and welfare—cause one of the biggest environmental problems in the world yet receive little attention.
The World Bank estimates that lead kills 5.5 million people per year, making it a bigger global killer than AIDS, malaria, diabetes and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is heavy, as is its contribution to global inequality—our research on the cognitive (认知的) effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.
But unlike many challenges faced by developing countries, lead poisoning is a problem that can be resolved through financial investment (财政投入). Better monitoring, research and rules can help protect children all over the world from the unpleasant effects of lead poisoning and reduce the massive global costs it brings.
(　)1.How does the author describe the lead problem in Paragraph 2
A.By listing some numbers.
B.By analysing hidden causes.
C.By making an interesting comparison.
D.By explaining its working principle.
(　)2.What can we learn about lead’s harm from the text
A.Lead enters poor countries in one way.
B.Lead leaking has been avoided in all the countries.
C.Lead will definitely not harm anymore.
D.Lead poisoning may make poor societies poorer.
(　)3.What can be done to solve lead poisoning in developing countries
A.Fixing these used batteries.
B.Reducing the cost of recycling lead.
C.Ignoring the illegal use of lead.
D.Putting certain effort and money.
(　)4.Which of the following is the best title for the text
A.The impacts of lead poisoning on man
B.The global lead poisoning problem
C.The ways to solve lead problem
D.The benefits of using electric vehicles

Food waste is a major issue in agriculture and in homes. If you grow your own food, the last thing you want is to let your hard work go to waste. 1.　　　　 It begins with the plants you choose, and goes right through to preservation (保存) of your harvests. Here are some tips for you.
When planning a food-producing garden, it’s very important to choose the right plants for the right places. Waste is far more likely to happen if you are growing plants that are not suited to the climate, soil and growing conditions. 2.　　　　 Make sure they do not just provide food today, but can also adapt to the changing climate. If you make the right plant choices, you are likely to get a good harvest.
Sometimes cooperation is key. People may often have more seeds (种子) than they really need, particularly in small gardens. However, seeds are usually only viable (能存活的) for a certain length of time. 3.　　　　 And you can also share skills and knowledge with each other.
4.　　　　 You might, for example, grow some strawberries inside a greenhouse, with others outdoors. Those grown under cover will typically be ready to harvest a little earlier. Or you can grow different varieties of plants.
Once you have grown your crops, it is important to be ready to preserve what needs to be preserved. This can happen in a range of different ways. You can freeze, pickle (腌制) or process a wide range of garden produce. 5.　　　　　
A.Communities can come together to harvest crops.
B.Many common weeds or flowers can be sources of food.
C.Preventing food waste in the garden is a long-term process.
D.So think about how you can create good systems in your garden.
E.Sharing them between households can avoid wasting their potential.
F.Make sure you know how to do so properly when harvest time comes.
G.Scheduling different harvest periods for certain crops can help avoid waste.

Earth Day 1.　　　　　　　(found) in 1970 as a day of education about environmental problems, and Earth Day 2020 occurred on Wednesday, April 22—the holiday’s 50th anniversary.
