Let’s learn more about wetlands. Some areas on Earth’s land are 16 by water or have water just below the soil. This may be all year round or for just part of the year. These 17 are called wetlands. Wetlands come in many forms. These 18 rivers, lakes, swamps (沼泽) and so on. Most large wetland areas have more than one of these forms. Wetlands are 19 to lots of different animals, such as frogs and snakes. Flying birds, like 20 geese and ducks, rest in wetlands during their long trips. And two-thirds of all the fish we eat 21 at least part of their lives in wetlands. Wetlands cover only 6 percent of the Earth’s surface, 22 they play a big role in nature. They can clean the 23 water from cities and farms. Wetlands can trap pollutants (截留污染物) in the water and keep them in the soil. During heavy rains, wetlands hold a lot of rainwater. What’s more, wetlands help slow climate change. They 24 plenty of CO2 and store it in the soil and plants. Wetlands 25 pull leaves, animal waste and other matter down from the surface of the water.

Koalas, which are often called koala “bears”, are tree-climbing animals and are seen as national symbols of Australia. However, recently the Australian government has announced (宣布) that koalas are endangered animals across much of the country. As a matter of fact, the country lost 30% of its koala population between 2018 and 2021, especially in New South Wales, according to a report from the Australian Koala Foundation. If nothing was done, New South Wales’ koalas would die out by 2050, research in June 2020 said. “This must be a wake-up call to Australia and the government to move much faster to protect the cute animals,” Josey Sharrad, a manager with the International Fund for Animal Welfare, said seriously. Koalas are dying out all over the country because of the climate change and the fast development of cities. People have seen some places that look like the moon—with dead and dying trees everywhere. After WWF-Australia and the International Fund for Animal Welfare called on the government to announce koalas as endangered in April, the government promised they would get more public support and protect koalas’ home — they live in the forests and woodlands. The Australian government is now doing its best to collect money to protect koalas. On the one hand, it has spent 36 million doing better health research and medical support to further help koala programs over the next four years. “We should never have allowed things to get to the point where we are at risk of losing a national symbol,” Environment Minister Susan Ley said. 39．What has the Australian government announced recently? 40．When would New South Wales’ koalas die out if nothing was done? 41．Why are koalas dying out all over the country? 42．Where do koalas live in Australia? 43．Besides the action mentioned (提及) in the article, what else can people do to protect koalas? 《Unit 7 The natural world grammar课后练习》参考答案 题号 16 17 18 19 20 21 22 23 24 25 答案 B D C A B D D B A C 题号 36 37 38 答案 D B C 1．quite a few 2．provide sth. for sb./provide sb. with sth. 3．all year round 4．too much 5．feed on 6．keep healthy 7．a lot of 8．covered with sand 9．store heat 10．sit under the shade of a tree 【解析】1．相当多，不少：quite a few，短语，故填quite a few。 2．为某人提供某物：provide sth. for sb./provide sb. with sth.，固定结构，故填provide sth. for sb./provide sb. with sth.。 3．全年，整年：all year round，短语，故填all year round。 4．太多：too much，短语，故填too much。 5．以……为食物：feed on，动词短语，故填feed on。 6．保持健康：keep healthy，动词短语，故填keep healthy。 7．许多，大量：a lot of，形容词短语，故填a lot of。 8．被沙子覆盖：covered with sand，短语，故填covered with sand。 9．储存热量：store heat，短语，故填store heat。 10．坐在树荫下：sit under the shade of a tree，动词短语，故填sit under the shade of a tree。 11．best 【详解】句意：在所有季节里，我最喜欢春天，因为气候温暖、色彩缤纷。短语Of all the seasons表示在三者及以上事物中进行比较，需使用副词最高级。well的最高级形式为best，应填best。 12．snowy 【详解】句意：下雪的天气让我们开车上班变得很困难。空格后为名词weather，需要形容词作定语修饰名词。snow为名词或动词，变为形容词形式snowy表示“下雪的；多雪的”，应填snowy。 13．is singing 【详解】句意：看！小鸟正在树枝上欢快歌唱，它的妈妈正在觅食。“Look!”是现在进行时标志性提示词，用来提醒观看正在发生的动作；同时while引导时间状语从句，从句使用现在进行时，主句时态保持一致。主语the little bird为单数，be动词用is，sing变动词-ing形式，应填is singing。 14．closed 【详解】句意：我们的老师发现窗户关着。分析句子，“find+宾语+形容词”结构意为“发现某物处于某种状态”，此处表达发现窗户关着，形容词作宾语补足语，closed“关着的”。故填closed。 15．waiting 【详解】句意：对不起，让你久等了。根据“I’m sorry to keep you…(wait) for so long.”可知，此处为固定短语keep sb doing sth“使某人一直持续做某事”，应用现在分词形式waiting“等待”。故填waiting。 16．B 17．D 18．C 19．A 20．B 21．D 22．D 23．B 24．A 25．C 【导语】本文介绍了湿地的定义、类型、生态功能及其对环境和生物的重要性。 【详解】16．句意：地球上的一些地区被水覆盖，或者土壤下面有水。 stopped停止；covered覆盖；controlled控制；polluted污染。根据“Some areas on Earth’s land are...by water”可知，一些地区被水覆盖。故选B。 17．句意：这些地方被称为湿地。 ways方式； names名称；habits习惯；places地方。根据前文“Some areas”可知，这里需填同类词“places”。故选D。 18．句意：这些包括河流、湖泊、沼泽等。 express表达；manage管理；include包括；divide分割。根据“...rivers, lakes, swamps (沼泽) and so on.”可知，后文列举湿地类型，需填“包括”。故选C。 19．句意：湿地是许多动物的家园，比如青蛙和蛇。 home家园；food食物；nature自然；road道路。根据后文“Flying birds, like..geese and ducks, rest in wetlands during their long trips.”可知，后文提到了一些动物的栖息地，所以这里指湿地是许多动物的家园。故选A。 20．句意：飞禽，如野雁和野鸭，在长途旅行中在湿地休息。 smart聪明的；wild野生的；weak虚弱的；strong强壮的。根据“geese and ducks”和语境可知，这里是指野生的鸟类。故选B。 21．句意：我们吃的鱼中有三分之二至少有一段时间是在湿地度过的。 find发现；save拯救；play玩耍；spend度过。根据“...at least part of their lives”可知，这里是指度过一段时光。故选D。 22．句意：湿地仅占地球表面6%，但它们在自然界中扮演着重要的角色。 or否则；so所以；and和；but但。前后为转折关系，表示湿地面积小但作用大。故选D。 23．句意：它们能净化来自城市和农场的脏水。 fresh新鲜；dirty脏的；clear清澈；cold寒冷的。根据后文“Wetlands can trap pollutants (截留污染物) in the water and keep them in the soil.”可知，湿地可以截留污染物，所以这里是指湿地能净化脏水。故选B。 24．句意：它们吸收大量的二氧化碳并将其储存在土壤和植物中。 take in吸收；give out释放；take away带走；give up放弃。根据上文“What’s more, wetlands help slow climate change.”可知，湿地可以减缓气候变化，所以这里是指湿地能吸收大量的二氧化碳。故选A。 25．句意：湿地还能把树叶、动物粪便和其他物质从水面拉下来。 ever曾经；still仍然；also还；even甚至。前文已列出湿地的一些功能，此处需递进补充其它功能。故选C。 26．The 27．his 28．to teach 29．lost 30．But 31．Finally 32．waiting 33．surprised 34．dead 35．at 【导语】本文讲述了南美洲一个人养了一只会模仿人类语言的鹦鹉，这只鹦鹉唯独不会说自己家乡“Catano”这个名字，主人尝试各种方法教它都失败，最后将其扔进鸡舍，结果鹦鹉却学着主人的语气威胁鸡的故事。 26．句意：这只鹦鹉很特别。此处特指上文提到的那只鹦鹉，用定冠词“The”，句首单词首字母大写。故填The。 27．句意：它不会说自己家乡Catano的名字。修饰名词“native town”要用形容词性物主代词，“he”的形容词性物主代词是“his”。故填his。 28．句意：这个人尽其所能教鹦鹉说“Catano”，但从未成功。“did everything he could”后接不定式表目的。故填to teach。 29．句意：起初，他很温和，但渐渐地他发脾气了。文章叙述的是过去的事情，用一般过去时，“lose”的过去式是“lost”。故填lost。 30．句意：但这只鸟永远不会重复这个名字。前文主人多次威胁鹦鹉，后文鹦鹉仍不重复名字，是转折关系，用连词“But”，句首单词首字母大写。故填But。 31．句意：最后，这个人放弃了。修饰整个句子要用副词，“final”的副词形式是“Finally”，句首单词首字母大写。故填Finally。 32．句意：在鸡舍里，有四只老母鸡等着被宰来做周日的晚餐。“chickens”和“wait”之间是主动关系，用现在分词作后置定语，“wait”的现在分词是“waiting”。故填waiting。 33．句意：他对所看到的感到惊讶。“be surprised by”是固定短语，意为“对……感到惊讶”。故填surprised。 34．句意：地上躺着三只死鸡，鹦鹉正在对第四只尖叫：“说‘Catano’，否则我就杀了你！”此处修饰名词“chickens”要用形容词，“die”的形容词形式是“dead”，意为“死的”。故填dead。 35．句意：地上躺着三只死鸡，鹦鹉正在对第四只尖叫：“说‘Catano’，否则我就杀了你！”“scream at”是固定短语，意为“对……尖叫”。故填at。 36．D 37．B 38．C 【导语】本文主要介绍了一个模拟台风形成的小实验，包括所需材料、操作步骤、观察到的现象以及关于台风结构的科普知识。 【详解】36．根据“What to do: Fill the bowl about half full with water.
