55、一个动词，意为“展示”，该句使用了一般将来时态，will+动词原形，故这里直接填动词原形。46harmful47planting/to be planted48to protect49provide50 is thrown are polluted51pouring52are harmed53differences54harm【解析】46句意：空气污染对我们的健康有害。根据形容词短语be harmful to对有害;对有危害;对是有害的。可知，此空故填harmful。47句意：为了使生活区更好，需要种植更多的树木。根据句意可知，此句是被动的含义，need doing 是需要被做有被动的意思，n

56、eed doing = need to be done可知，此空故填. planting/to be planted。48句意：保护环境是每个人的责任。根据句意可知，此句是强调句型，it是形式主语，真正的主语是后面的动词不定式，此空故填to protect 。49句意：水和土壤帮助我们提供必要的食物和饮料。根据当help作为动词，其中 to 可以省略. 所。helpdo sth 是 helpto do的省略形式，此空故填provide。50句意：在许多地方，垃圾被扔进湖泊和河流。那么多人被污染了。根据句意可知，此句是一般现在时态的被动语态，, rubbish是不可数名词，助动词故用is；So

58、arm to加害，损害。可知，此空故填harm。【点睛】这个题目是用所给单词的正确形式填空，考查单词在具体语境中的使用。做题时，应根据句意、单词在句中的作用以及句中使用的句型等，使用单词的正确形式。常考查的知识点包括：名词的复数；动词的时态、语态、非谓语动词；形容词和副词的基本用法以及比较级和最高级的用法等。55Discussions【解析】【分析】句意：两位领导人之间的讨论仍在继续。根据句子结构，空处的词是作主语，结合空后are可知，空处应用名词复数形式；discuss，讨论，动词，对应的名词是discussion，复数形式为discussions，句首首字母大写。故填Discussions

59、。56turn off the tap when brushing teeth57use both sides of paper58are the results of59done a lot to60is harmful to61 Not only but also has been to62depend nature resources to63was thrown away64become a serious problem65 reduce dust keep the air clean【解析】56分析语境可知，句子是一般疑问句，是询问一般状况，应用一般现在时；句子中有助动词do，因此

60、后面的动词用动词原形。关闭水龙头：turn off the tap；刷牙：brush ones teeth；“当你刷牙时”，为when引导的时间状语从句，应为现在进行时，其结构是：am/is/are+动词的现在分词。当主语相同时可以省略主语和be,故答案为turn off the tap when brushing teeth57由英语和汉语的翻译比较可知，本题缺少了“使用纸的两面”的翻译。使用：use；纸的两面：both sides of paper；本题考查try to do sth. 后面用动词不定式。故答案为use both sides of paper58由英语和汉语的翻译比较可知，

61、本题缺少了“的结果”的翻译。“的结果”：the results of；results“结果”，名词复数，因此本题的be 动词用are。故答案为are the results of59由英语和汉语的翻译比较可知，本题缺少了“已经做了很多”的翻译。做了很多：do a lot；根据汉语的语境可知，本题的时态为现在完成时，其结构是：has/have +动词的过去分词。do的过去分词为done。本题要用动词不定式做目的状语。故答案为done a lot to60由英语和汉语的翻译比较可知，本题缺少了“对有害”的翻译。“对有害”：be harmful to；主语Water pollution，是单数，因此

62、be动词用is；故答案为is harmful to61由英语和汉语的翻译比较可知，本题缺少了“不但而且和去过”的翻译。英语中的“不但而且”：not onlybut also；去过某地：have/has been to+地点；本题遵循就近原则。离谓语最近的his father是单数，因此助动词用has。故答案为 (1).
