But now people take too much water...them.”和备选词可知，此处指“人们从河流里取走了太多水”，from“从”符合语境。故选C。 29．句意：我一年比一年变小。year by year“逐年地，一年一年地”，固定搭配。故选F。 30．句意：少取点水，否则我将在未来100年内干涸。根据“Take less water...I’ll dry up within the next 100 years.”可知，此处是“祈使句+or+陈述句”，表示“少取点水，否则死海将在未来100年内干涸”。故选B。 31．D 32．C 33．B 34．C 35．A 36．B 37．D 38．B 39．C 40．D 【导语】本文是一篇说明文。主要介绍了人类的所作所为对自然界造成的伤害，其中包括塑料垃圾、过度开采等，并且提倡人类对大自然无法分解的垃圾进行回收利用，保护自然环境。 31．句意：例如，当一个动物死了，它可以成为另一个动物的食物。 other其他的，后接复数名词；others其他人/物；the other特指两个中的另一个；another泛指三者或以上的另一个，后接单数名词。根据“it becomes ... animal’s food”可知，此处泛指“另一个动物的食物”，animal为单数名词，应用another。故选D。 32．句意：我们的垃圾杀死动物并污染水和土壤。 cleans打扫；makes使；pollutes污染；washes洗。根据“Our rubbish kills animals and ... water and soil”可知，垃圾应是污染水和土壤。故选C。 33．句意：如果我们继续制造过多的垃圾，问题只会变得更糟。 Before在……之前；If如果；When当……时候；Why为什么。“we continue making too much rubbish”是“the problem will only get worse”的条件，应用If引导条件状语从句。故选B。 34．句意：如果大自然无法再利用这些垃圾，我们就必须自己回收。 them它们；their它们的；it它；itself它自己。根据“If nature can’t use the rubbish again, we must recycle...”可知，是必须回收垃圾，rubbish是不可数名词，需用it来指代。故选C。 35．句意：我们应该清理垃圾，因为大自然无法做到。 nature自然；water水；soil土壤；plastic bags塑料袋。根据“We should clean up the rubbish because ...can’t.”可知，因为大自然无法分解垃圾，所以我们应该清理。故选A。 36．句意：地球富含水和树木等自然资源，但这些资源并非取之不尽。 poor贫穷的；rich富有的；tiny微小的；great伟大的。根据“The Earth is ... in natural materials like water and trees”可知，后文提到资源有限，所以此处应描述地球资源丰富。故选B。 37．句意：地球富含水和树木等自然资源，但这些资源并非取之不尽。 and和；so因此；or或者；but但是。前句说地球资源丰富，后句说这些资源不是无尽的，是转折关系，所以用but。故选D。 38．句意：我们消耗自然资源的速度远远快于地球重新生产它们的速度。 fast快地，原形；faster较快地，比较级；slowly慢地；more slowly较慢地，比较级。根据“We use up our natural materials much ... than the Earth is able to produce them again.”可知，应是消耗资源的速度比地球再生速度快，much修饰比较级。故选B。 39．句意：例如，我们每年砍伐超过6000平方英里的森林，但一棵新树需要近25年才能长大。 cut out删除；cut up切碎；cut down砍倒；cut into打断。根据“each year we ... more than 6,000 square miles of forest”可知，此处指砍伐森林。故选C。 40．句意：例如，我们每年砍伐超过6000平方英里的森林，但一棵新树需要近25年才能长大。 plant种植；die死；stop停止；grow生长。根据“but it takes almost 25 years for a new tree to...”可知，新树需要25年来生长。故选D。 41．D 42．E 43．A 44．C 45．B 【导语】本文介绍了几种节约用水的方法。 41．根据“The amount of water we use. or waste, in day to day life has a direct impact on the environment. ”可知，空格前提到“我们每日的用水量，或者说浪费的水量，对环境有着直接的影响”。下文是节约用水的具体方法。D项“今天我们将聊一聊如何避免水的浪费”起到承上启下的作用。故选D。 42．根据标题“Step 1: Shower VS Bath”可知，这部分讲的是应该洗淋浴还是用浴缸。E项“用浴缸洗一次澡可以用掉高达100升的水！”与本段主旨相符。故选E。 43．根据标题“Step 2: Running taps ”可知，本段主要讲述“流着水的水龙头”。A项“如果你不用水的话，不要开着水龙头。”与本段主旨相符。且与下句“如果在刷牙的时候关掉水龙头，你每分钟可以节约5升水”衔接紧密。故选A。 44．根据“If so, fix them fast. ”可知，空格前句提到“如果是这样的话，快点修好它们”。C项“这样每周可以节约高达140升的水”与上文衔接紧密。故选C。 45．根据“Using your washing machine when you only have a few items is a waste of energy and water.”可知，在只有几件衣物的时候使用洗衣机既浪费能源也浪费水。B项“请在有足够多的衣物时使用洗衣机”与上文衔接紧密。故选B。 46．C 47．A 48．C 49．B 50．A 【导语】本文是一篇说明文，通过农民杀鹰导致鼠害泛滥和人类干预导致长颈鹿濒危的例子，警示人们维护自然平衡的重要性，破坏生态链会带来严重后果。 46．细节理解题。根据“some farmers were worried because hawks took many of their chickens, so the farmers killed many hawks.”可知，农民杀鹰是为了保护他们的鸡，故选C。 47．细节理解题。根据“But soon they had new worries.

But people killed many lions to defend the giraffes.”可知，人们杀狮子是为了“保护”长颈鹿，“defend”意为“保护”，和“protect”同义，故选B。 50．最佳标题题。全文通过两个例子说明破坏自然平衡的后果，强调保持生态平衡的重要性，所以“The Balance of Nature”最符合，故选A。 51．a green area 52．people’s health 53．day and night 54．some plants 55．sets a great example 【导语】本文介绍了中国为治理塔克拉玛干沙漠沙尘暴而建造的3046公里“绿色长城”。 51．根据“But do you know the ‘Green Great Wall’? It is a green area around the Taklamakan Desert (沙漠) in Xinjiang.”可知，“绿色长城”是新疆塔克拉玛干沙漠周围的一片绿地。故填a green area。 52．根据“Sandstorms (沙尘暴) from the desert were bad for the weather, farming, and people’s health.”可知，来自沙漠的沙尘暴对天气、农业和人们的健康都有害。故填people’s health。 53．根据“Many people worked day and night to plant trees and grow other plants.”可知，许多人日以继夜地种树和种植其他植物。故填day and night。 54．根据“People also use some plants in the green belt to make medicine.”可知，人们也用绿化带里的一些植物来制药。故填some plants。 55．根据“The green belt around the Taklamakan Desert sets a great example for other countries with deserts.”可知，塔克拉玛干沙漠周围的绿化带为其他沙漠国家树立了一个很好的榜样。故填sets a great example。 56． to save 【详解】根据句意可知，此处表示“节约水是重要的”，使用“it is +形容词+to do sth.”这一结构来表达“做某事是……的”，其中“to do sth.”是真正的主语，“it”作形式主语，“节约”对应的英文单词是“save”，所以此处应用“to save”。故填to；save。 57． throw away 【详解】throw away“扔”，情态动词shouldn’t后用动词原形，故填throw；away。 58． provide for 【详解】根据中英文对照可知，空格处表示“为……提供”，provide sth. for sb.“为某人提供某物”，此句描述客观事实，用一般现在时，主语“Trees”是复数，谓语动词用原形。故填provide；for。 59． throw away 【详解】根据中英文对应可知，需要翻译“扔掉”，throw away“扔掉”，空格前为祈使句，其否定结构为Don’t do sth，后接动词原形。故填throw；away。 60．take steps 【详解】根据题干可知，空处缺少“采取措施”，应用短语take steps表示，空前有情态动词应用动词原形。故填take steps。 61．valuable 62．to save 63．so 64．carefully 65．once 66．collect 67．reuse 68．brushing 69．people 70．a 【导语】本文主要讲述了在干旱炎热的沙漠地区，水非常珍贵，Ali和他的家人如何节约用水。 61．句意：在炎热干旱的地方，水对人们来说是如此珍贵。“is”后接形容词作表语，“value”的形容词形式“valuable”。故填valuable。 62．句意：他从父母和祖父母那里学习如何节约用水。“how to do sth.”是固定结构，意为“如何做某事”。故填to save。 63．句意：在沙漠里，下雨很少，所以下雨时他们必须非常小心地收集雨水。前后句是因果关系，“so”表结果。故填so。 64．句意：在沙漠里，下雨很少，所以下雨时他们必须非常小心地收集雨水。collect是动词，需用副词carefully修饰。故填carefully。 65．句意：他们一周只能快速洗一次澡。once a week意为“一周一次”，表示做某事的频率。故填once。 66．句意：洗澡时，他们必须把水收集起来，这样他们洗澡后可以重复使用水。must是情态动词，后接动词原形。故填collect。 67．句意：洗澡时，他们必须把水收集起来，这样他们洗澡后可以重复使用水。把洗澡水收集起来后，可以重复使用。can后接动词原形reuse“重复使用”。故填reuse。 68．句意：他们刷牙时会关掉水龙头。while doing sth.表示“在做某事期间”，空处应是brushing。故填brushing。 69．句意：沙漠里有很多像阿里和他家人一样的人。此处指很多人，people是集合名词，无需加s。故填people。 70．句意：由于他们的辛勤付出，他们共同带来了改变。make a difference是固定短语，表示“产生影响，有所作为”。故填a。 71．例文： How to Save Water in Our Daily Life?
