四、阅读理解,本大题共5小题,每小题3分,共15分。阅读下列短文,根据短文内容选择最佳选项。
Global (全球的) warming is like a fever for our Earth. It happens when our planet gets hotter because there’s too much of a gas called carbon dioxide (CO2) in the air. Cars, factories, and even cutting down trees can make this gas.
Think of Earth wearing a big blanket; the more carbon dioxide in the air, the thicker the blanket gets. This blanket keeps the Earth warm, but if it gets too thick, the Earth can get too hot. That’s why we need to keep the blanket just right, not too thick and not too thin.
When Earth gets too hot, ice at the top and bottom of the world starts to turn into water. This is a problem because animals like polar bears and penguins (企鹅) need the ice to live. It’s also bad because it can make the ocean water rise, and that can flood places where people live.
The good thing is, there are many clever people coming up with ideas on how to cool our planet down. Helping Earth feel better can start with steps as simple as recycling our trash, enjoying a bike ride instead of taking a short car trip or choosing toys made from materials that are good for the planet. All of us can be Earth’s doctors in a way, making sure it doesn’t get too hot with too heavy a blanket. It’s very important that every one of us takes part in caring for our big home, keeping it just cool enough and just warm enough. After all, taking care of Earth is like taking care of our big family house—it keeps us all safe, healthy, and happy.
根据材料内容选择最佳答案。

A. B.
C. D.
28.What does the word "that" refer to (指代) in the text
A.The rising of sea water. B.The cutting down of trees.

A.Earth’s fever is dangerous for all living things.
B.People are creating new gases to warm the planet.
C.Polar bears and penguins are helping to save Earth.
D.Steps everyone can take to help cool down the planet.

参考答案
1.hope
【详解】句意:我希望地球日活动能取得成功。结合音标/h p/和语境,对应的英文名词是“hope”;“It’s one’s hope that...”是常用句式,意为“某人希望……”。
2.recycle
【详解】句意:我们应该回收纸张、易拉罐和瓶子。结合音标/ ri sa kl/和语境,对应的英文动词是“recycle”;“should”后接动词原形。
3.program
【详解】句意:我们可以建立一个学校项目。给定音标/ pr ɡr m/对应的单词是program,词义为“项目、计划、课程”,此处school program指学校项目,不定冠词a后接可数名词单数,符合语法和句意要求。
4.rubbish
【详解】句意:公园里有很多垃圾。结合音标/ r b /和语境,对应的英文不可数名词是“rubbish”;“a lot of”可修饰不可数名词。
5.make
【详解】句意:你今年打算制定一些环保决心吗?句中“Are you going to”表明句子描述的是将来打算要做的事情,是一般将来时的结构,“be going to”后需接动词原形make。
6.was
【详解】句意:理查德上个月从巴黎度假回来了。“last month”可知,本句时态为一般过去时,结合主语为第三人称单数,因此be动词填写过去式was。
7.will help
【详解】句意:如果我们都多回收利用,我们就会帮助保持我们的城市清洁。句中“If we all recycle more”是if引导的条件状语从句,用一般现在时表将来,主句需用一般将来时,即“will+动词原形”结构。
8. were leaving following
【详解】句意:他们说他们将在接下来的一周动身去伦敦。直接引语的现在进行时表将来,变间接引语时改为过去进行时were leaving;时间状语next week改为the following week。故填were leaving;following。
9.eating
【详解】句意:我不习惯晚上吃这么多。“be used to doing sth.”是固定搭配,意为“习惯于做某事”,“eat”表示“吃”,是动词,此处用动名词形式,故填eating。
10.used
【详解】句意:她过去留着长发,不是吗? 分析题干可知,此处应用“used to+动词原形”表示“过去常常做某事”,因此空格处应填“used”。故填used。
11.buildings 12.lives 13.killing 14.importance 15.action
【导语】本文是一篇议论文,指出人类捕杀动物、破坏栖息地的行为会导致动物濒危,强调动物在生态系统中的重要性,呼吁人们采取行动保护动物。
11.句意:一些人砍伐森林,为建筑和道路腾出更多空间。根据“Some cut down forests to make more space for…and roads”并结合备选词可知,此处表示人类活动中“建筑”,build的名词形式“buildings”符合语境,故填buildings。
12.句意:这使许多动物失去生命和家园。根据“This makes many animals lose their…and homes”并结合备选词可知,此处表示动物失去“生命”,主语为“many animals”,是复数概念,life的复数形式“lives”符合语境,故填lives。
13.句意:如果人们不停止杀害它们,它们可能有一天会灭绝。根据“They may die out one day if people don’t stop…them”并结合备选词可知,“stop doing sth”表示停止正在做的事,kill的动名词形式“killing”符合语境,故填killing。
14.句意:动物在生态系统中非常重要。根据“Animals are of great…in the ecosystem”并结合备选词可知,“be of great importance”是固定搭配,意为“非常重要”,important的名词形式“importance”符合语境,故填importance。
15.句意:人们应该采取行动保护它们。根据“People should take…to protect them”并结合备选词可知,“take action”是固定搭配,意为“采取行动”,action符合语境,故填action。
16.What a useful robot it is!
【详解】分析所给词及标点,本句是感叹句。结构是What + a/an + adj + 名词 + 主谓!What“多么”,引导感叹句,a useful robot“一个有用的机器人”,作主语相关的核心名词短语,it是主语,is是系动词。故填What a useful robot it is!“它是个多么有用的机器人啊!”
17.tap
【详解】原句中“水龙头”是关键词,表示“水龙头”的英文单词是tap,turn off the tap“关掉水龙头”。
18.basin
【详解】原句中“盆”是关键词,表示“盆”的单词是basin。洗手在一个盆里洗,用其单数形式。故填basin。
19.size
【详解】结合中文可知,句子缺少“尺码”,对应单词“size”,此处用名词单数。
20.bath
【详解】原句中“洗澡”是关键词,表示“洗澡”的英文表达之一是“bath”,“take a hot bath”表示“洗个热水澡”。
21.produces
【详解】空格处表示“出产”,需要动词作谓语;时间状语“every year”说明用一般现在时;主语This farm是第三人称单数,谓语用第三人称单数形式produces。
22.worse
【详解】原句中“更糟了”是关键词。get worse表示“变得更糟了”,worse是形容词比较级,故填worse。
23.brush
【详解】原句中“刷”是关键词,表示“刷”的英文是brush,是动词,remember to后接动词原形。

【详解】原句中“不需要的”是关键词,表示“不需要的”的英文单词表达之一是unnecessary,作表语。
25. would visit the next day
【详解】句意:“我们明天去博物馆,”他们说。此处缺“将会参观”和“明天”,直接引语变间接引语时,主句为一般过去时,从句要改为过去将来时,will变为would,tomorrow变为the next day,故填would visit;the next day。
26.They said that they had seen the movie the night before.
【详解】句意:他们说他们前一天晚上看了那部电影。根据题目要求可知,当直接引语变为间接引语时,主句为一般过去时,从句需改为过去完成时had seen;人称we改为they;时间状语last night改为the night before。故填They said that they had seen the movie the night before.
27.D 28.A 29.D 30.B 31.B
【导语】本文讲述了全球变暖的原因,即空气中二氧化碳增多,还阐述了全球变暖带来的问题,如冰川融化等,以及人们可以采取回收垃圾、骑车出行、选择环保玩具等措施来帮助地球降温。
27.细节理解题。根据文中“Think of Earth wearing a big blanket; the more carbon dioxide in the air, the thicker the blanket gets.”可知,空气中的二氧化碳像一条毯子,故选D。
28.词句猜测题。根据文中“When Earth gets too hot, ice at the top and bottom of the world starts to turn into water. This is a problem because...”可知,“That”指代的是海水水位上升,故选A。
29.主旨大意题。根据文中“The good thing is, there are many clever people coming up with ideas on how to cool our planet. Helping Earth feel better can start with steps as simple as...”可知,该段主要讲每个人可以采取措施来帮助地球降温,故选D。
30.细节理解题。根据文中“Helping Earth feel better can start with steps as simple as recycling our trash, enjoying a bike ride instead of taking a short car trip or choosing toys made from materials that are good for the planet.”可知,文中未提及“Planting more trees”,故选B。
31.最佳标题题。根据全文内容,主要围绕全球变暖,以及人们如何采取措施给地球降温展开,选项D“给地球降温”最适合做标题,故选B。
