Mutunkei follows in the footsteps of the late Kenyan Nobel Peace Prize winner Wangari Maathai who founded the Green Belt Movement in 1977.This initiative has resulted in the planting of over 51 million trees to date. In 2018, Lesein decided to start a movement of his own.He started by planting one tree for every goal he scored during a football match.He called it Trees4Goals, and it has grown so much that he now plants 11 trees, one for each member of his team, every time he scores.Through this, he wants to inspire young people, specifically his fellow athletes, to follow in his footsteps, take nature conservation seriously, and promise to plant trees every time they score.As a result, some of them have adapted this practice for their sports.“Seeing that they're taking that responsibility because of the project I started, for me, that is the biggest achievement，” he said. The initiative has caught the attention of English football club Arsenal and Kenya's Ministry of Environment and Forestry, which he now works with regularly and gets advice from. Like Green Belt Movement, Trees4Goals, which has planted 5,500 trees so far, has made it.While Lesein has received some recognition for his initiative, he sets his sights on making it a worldwide phenomenon.“Football is a universal game, and climate change is a universal problem，” he explains.“It has the power to unite, educate and inspire my generation to create a safer and greener future.” This is why he wants to work with the world's biggest football federation FIFA. As for what others can do to fight deforestation or other environmental concerns, the teenager says it's important to just get involved in some way, no matter how small. 语篇解读：本文是一篇记叙文。在肯尼亚长大的Lesein Mutunkei是一名足球队员，他发起了“一球一树(Trees4Goals)运动”：每进球一次，他就为球队的每一位成员种一棵树，激励年轻人去保护环境。 1．What made Lesein get interested in environmental protection?

A．Fame is a great thirst of the young. B．A youth is to be regarded with respect. C．Positive thinking and action result in success. D．Success means getting personal desires satisfied. √ 解析：推理判断题。根据全文内容可知，Lesein从小耳濡目染，很有环保意识，后受到启发，发起了“一球一树运动”并取得了成功。由此可推知，他的故事说明：积极的思想和行动会带来成功。 (二)阅读七选五 Coral reefs, found only in warm, shallow waters, are made up of groups of tiny animals called coral. When corals die, they leave behind hard skeletons that build up and form reefs. As new corals grow on top, the reefs grow bigger. ___ Some look like boats, while others are shaped like horns. Some look almost like brains. 5 Coral reefs take centuries to grow. ___ Some threats are natural. Storms bring giant waves that can destroy the coral to bits and pieces. When heavy rains wash soil off the land, the soil ends up in the water, and it blocks out the sunlight that corals need to grow. 6 Other threats, such as careless diving, come from humans. ___ Reef fish are highly sought by supermarkets and restaurants. To catch them alive so that they stay fresh longer, some fishermen use a poison called cyanide. They spray the poison into the water, and it stuns (使……昏迷) the fish, but does not kill them. However, the poison can kill the coral and other reef inhabitants as well. Authorities are working hard to stop this kind of fishing. ___“Fish need the reefs，” they explain. “If you kill the reefs, the fish will disappear. You are actually killing your own future.” 7 8 Another threat to reefs is harder to control. It is the rising water temperatures. Water that is too warm causes corals to get “bleached” or lose their color. Then they die. Some scientists think that global warming may be causing ocean waters to warm up quickly. ___ 9 A．Be conscious when buying sea fish. B．Destructive fishing is another example. C．They teach fishermen about the harm it causes. D．They come in many colors and different shapes. E．However, they can be destroyed much more quickly. F．If this continues, reefs around the world will disappear. G．Climate change is one of the major threats to coral reefs' survival. 语篇解读：本文是一篇说明文。文章主要介绍了珊瑚礁的形成和面临的危险。 5．解析：选D　根据下文“Some look like boats, while others are shaped like horns.Some look almost like brains.”可知，D项“它们有多种颜色和不同的形状”衔接下文，符合语境。 6．解析：选E　根据上文“Coral reefs take centuries to grow.”和下文“Some threats are natural.”可知，空处与上文构成转折关系，下文描述珊瑚礁被破坏的情况。故E项“然而，它们被摧毁却快得多”承上启下，符合语境。 7．解析：选B　根据下文可知，接下来要描述的是捕鱼对珊瑚礁造成的破坏。故B项“破坏性捕鱼是另一个例子”衔接下文，符合语境。 8．解析：选C　根据上文“Authorities are working hard to stop this kind of fishing.”和下文可知，空处应描述当局为阻止这种破坏性捕鱼活动做出的努力。故C项“他们向渔民讲解其造成的危害”承上启下，符合语境。 9．解析：选F　根据上文可知，这里提到全球变暖对珊瑚礁的威胁。故F项“如果这种情况继续下去，世界各地的珊瑚礁将会消失”承接上文，符合语境。 本课结束 $$
