重点话题30人与自然-环境保护 语法填空 【同步拓展阅读】2024-2025学年高二英语阅读提升(通用版) “人与自然-环境保护”的语法填空高频单词和短语: 一、高频单词 1.名词 environment:环境 pollution:污染 species:物种 conservation:保护;保持 ecology:生态;生态学 2.动词 protect:保护 reduce:减少,降低 preserve:维护,保护,保存;维持。 release:排放;释放;发布 sustain:维持;遭受;承受住 3.形容词 environmental:环境的,有关环境的 harmonious:和谐的 global:全球的,全世界的 sensitive:敏感的;灵敏的 sustainable:可持续的 4.副词 frequently:频繁地,经常 globally:全球地,在全球范围内 ecologically:从生态学的观点看 二、高频短语 carbon dioxide:二氧化碳 fossil fuel:化石燃料 on behalf of:代表 dozens of:许多,很多 take measures to:采取措施做某事 be concerned about:关心;担忧 in harmony with:与…… 和谐相处 be home to:是…… 所在地 contribute to:有助于,促成 at risk of:处于…… 的风险 三、如何运用这些高频单词和短语来提高语法填空的准确率? 高二英语语法填空中,熟练运用 “人与自然 - 环境保护” 主题的高频单词和短语可从理解语境、分析句子成分、注意固定搭配等方面入手来提高准确率,以下是具体方法: 1.理解语境 通读全文:在开始答题前,先快速通读全文,了解文章关于 “人与自然 - 环境保护” 的大致主题和内容方向。判断文章是在讲述环境污染问题、环保措施,还是人与自然的关系等,以便对整体语境有一个初步的把握,为后续准确运用高频单词和短语奠定基础。比如,如果文章是在讲全球变暖问题,那么涉及 “global warming”“carbon dioxide” 等相关词汇的可能性就较大。 根据上下文推断:在具体填空时,要紧密结合上下文的语境来选择合适的高频单词或短语。关注前后句之间的逻辑关系、语义关联,确保所填内容在意思上与上下文连贯一致。例如,若前文提到了某种环境问题,后文说需要采取行动,那么就可能要填 “take measures to” 这个短语来衔接。 2.分析句子成分 确定词性需求:通过分析句子结构,判断所缺成分的词性,然后从相应词性的高频单词中选择合适的词。比如,若句子缺少主语,可能需要从 “environment”“pollution”“species” 等名词中选择;若缺少谓语动词,就考虑 “protect”“reduce”“preserve” 等动词。 判断修饰关系:如果需要填的是修饰名词的词,要考虑用形容词,如 “environmental”“harmonious”“sustainable” 等;若修饰动词、形容词或其他副词,则要用副词,像 “frequently”“globally” 等。例如,“The ___ (frequent) of extreme weather events is increasing.” 中,根据句子结构可知这里需要用名词形式 “frequency”,而不能直接用形容词 “frequent”。 3.注意固定搭配 积累并牢记:把 “人与自然 - 环境保护” 主题中的常见固定搭配和短语,如 “be concerned about”“in harmony with”“be home to” 等牢记于心。在语法填空中,一旦看到相关的提示词或语境,就能迅速反应出应该使用哪个固定搭配。 注意搭配的完整性:在填写固定搭配时,要确保搭配的各个部分都完整、正确。比如 “contribute to” 中的 “to” 是介词,后面要接名词或动名词形式,如果写成 “contribute for” 就是错误的。 4注意语法规则 词形变化:根据语法规则,对高频单词进行正确的词形变化。比如,名词可能需要根据语境变为复数形式,如 “species” 单复数同形,但在表示多个物种时要用 “species”;动词要根据时态、语态和主谓一致等进行变化,如 “Many species are being ___ (threaten) by human activities.” 中,要用 “threatened” 来构成被动语态。 短语的语法功能:了解高频短语在句子中的语法功能,如 “take measures to” 后面要接动词原形,“at risk of” 后面要接名词或动名词等。例如,“We are at risk of ___ (lose) many precious species.” 中,要用 “losing”。 5.检查与验证 整体检查:完成填空后,再次通读全文,检查所填的高频单词和短语是否使文章在语法上正确、语义上通顺、逻辑上连贯。尤其要注意所填内容与上下文的衔接是否自然,有没有出现语法错误或搭配不当的情况。 细节检查:检查单词的拼写是否正确,短语的使用是否符合习惯用法,以及语法形式是否准确。比如,“sustainable” 不要误写成 “sustanable”,“be home to” 中的 “to” 不能遗漏等。 四、高二英语“人与自然 - 环境保护” 主题下语法填空的答题技巧 高二英语 “人与自然 - 环境保护” 主题下的语法填空有一定的答题技巧,涵盖快速浏览、判断词性、分析句子结构、考虑固定搭配等方面,以下具体介绍: 1.快速浏览全文 把握主题方向:迅速浏览文章,确定是聚焦于环境污染现象、环保行动措施,还是人与自然的和谐关系等具体方向。比如文章若围绕森林砍伐展开,可能会涉及 “deforestation” 等相关词汇。 了解大致内容:知晓文章是说明性、议论性还是叙述性,明确文章的整体框架和大致内容,为后续填空建立整体认知。 2.精准判断词性 根据句子成分判断:若空格处在主语或宾语位置,通常需填名词,如 “____ protection is of great importance”,这里就可能填 “Environmental” 对应的名词 “Environment”;若在谓语位置,一般是动词,如 “Humans should ____ (protect) the ecosystem”,需填动词 “protect”;修饰名词用形容词,修饰动词、形容词或其他副词用副词。 依据上下文逻辑判断:根据上下文的语义逻辑来确定词性。如前文说 “Pollution is a serious problem”,后文提到 “it affects our life ____”,根据逻辑这里需要一个副词来修饰 “affects”,可能填 “seriously”。 3.仔细分析句子结构 确定从句类型:若句子中有从句,要判断是定语从句、名词性从句还是状语从句等,然后根据不同从句的特点来填空。比如 “The place ____ we live is facing environmental problems”,这里是定语从句,先行词是 “place”,在从句中作地点状语,所以填 “where”。 注意并列句和复合句:对于并列句,要注意前后句的逻辑关系和时态一致性;复合句要注意主从句之间的关系和时态搭配。例如 “And” 连接的并列句,前后句的时态和结构通常保持一致。 4.考虑固定搭配与习惯用法 短语搭配:牢记 “人与自然 - 环境保护” 主题相关的固定短语,如 “be harmful to”“in favor of”“make a contribution to” 等,根据语境准确运用。如 “He is always ____ favor of environmental protection activities”,应填 “in”。 习惯用法:注意一些单词的习惯用法,如 “it is + adj. + to do sth.” 结构,“It is necessary ____ (take) action to protect the environment”,就需要填 “to take”。 5.关注语法规则与特殊情况 时态和语态:根据上下文语境和时间状语来确定时态,同时注意主被动语态。如 “Many trees ____ (cut) down every year”,根据 “every year” 可知用一般现在时,“trees” 和 “cut” 是被动关系,所以填 “are cut”。 主谓一致:确保主语和谓语在人称和数上保持一致。如 “The environment, together with all the living things in it, ____ (need) our protection”,这里的主语是 “The environment”,是单数,所以填 “needs”。 词性转换特殊情况:有些单词的词性转换有特殊规则,如 “pollute” 的名词形式是 “pollution”,形容词形式是 “polluted” 或 “polluting”,要准确记忆和运用。 6.检查答案 语法检查:检查所填内容在语法上是否正确,包括词性、时态、语态、主谓一致、从句引导词等是否使用正确。 语义检查:通读全文,确保所填内容使文章语义连贯、逻辑合理,符合 “人与自然 - 环境保护” 的主题。 五、高二英语“人与自然 - 环境保护” 主题下语法填空的考法考点 高二英语 “人与自然 - 环境保护” 主题下的语法填空主要围绕词汇、语法、语篇理解等方面设置考法考点,具体如下: 1.词汇考点 词性转换 常考形容词与名词、动词与名词、形容词与副词之间的转换。例如:“environment”(名词)与 “environmental”(形容词),“pollute”(动词)与 “pollution”(名词),“frequent”(形容词)与 “frequently”(副词)等。要求考生根据句子成分和语境准确判断所需词性并进行正确转换。 固定搭配与短语 涉及与主题相关的大量固定搭配和短语,如 “be concerned about”“contribute to”“in harmony with”“take measures to”“be home to” 等。考查考生对这些搭配和短语的记忆及在语境中的正确运用。 2.语法考点 动词的时态和语态 结合上下文语境,考查一般现在时、一般过去时、现在进行时、现在完成时等时态,以及主动语态和被动语态的用法。例如:“The air quality in the city ____ (improve) in the past few years.” 应填 “has improved”,考查现在完成时。 可能会出现一些表示时间的标志词或根据上下文逻辑来确定时态和语态。 非谓语动词 考查不定式、动名词、分词作主语、宾语、定语、状语等。如 “____ (protect) the environment is our responsibility.” 中,“To protect” 或 “Protecting” 作主语。 要求考生掌握非谓语动词的各种用法及在不同语境中的区别。 3.从句 定语从句:考查关系代词(that, which, who, whom, whose)和关系副词(where, when, why)的用法,如 “I still remember the park ____ we planted trees last year.” 需填 “where”。 名词性从句:包括主语从句、宾语从句、表语从句和同位语从句,考查连接词(that, whether, if, what, who, when, where 等)的选择。 状语从句:考查时间、地点、原因、条件、让步等状语从句的连接词,如 “____ it rains tomorrow, we will still go to pick up rubbish in the park.” 应填 “Even if”。 4.主谓一致 考查主语为单数或复数时,谓语动词的形式变化。如 “Either you or he ____ (be) responsible for the project of environmental protection.” 根据就近原则应填 “is”。 涉及一些特殊情况,如集体名词作主语、由 with, together with 等连接的并列主语等的主谓一致问题。 5.冠词、介词和代词 冠词:考查不定冠词 a/an 和定冠词 the 的用法,如 “____ elephant is a symbol of the natural environment.” 应填 “An”。 介词:考查与主题相关的介词搭配,如 “in, on, at, for, of” 等在不同语境中的用法。 代词:考查人称代词、物主代词、反身代词、不定代词等的用法,如 “Everyone should do ____ (they) part to protect the environment.” 应填 “their”。 6.语篇理解考点 上下文逻辑关系 要求考生根据文章的逻辑关系,填写合适的连接词或过渡词,如 “however”“therefore”“besides”“moreover” 等,使文章语义连贯。 例如:“The government has taken many measures to protect the environment. ____, there is still a long way to go.” 这里应填 “However”,表示转折关系。 词汇复现与语境推断 利用词汇复现(原词复现、同义词复现、反义词复现等)来设置考点,考生需要根据上下文出现的相关词汇来推断空格处的答案。 如前文提到 “pollution”,后文可能会出现 “reduce pollution”“combat pollution” 等相关表达,通过这种联系来考查考生对语境的理解和词汇的运用能力。 六、“人与自然-环境保护”语法填空精练题 (24-25高二上·河南濮阳·期末)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式,并将答案填写在答题卡上。 A wild Siberian tiger 1 (spot) near Changbai Mountain in Northeast China’ s Jilin Province on Tuesday, marking the return of the species 2 the mountain after 30 years.

Over the past seven decades, continuous efforts have increased the county’s green coverage 52 68 percent, turning barren land into 53 oasis (绿洲), which shows how China’s national efforts are transforming the environment. China’s forest coverage rate has risen from 8.6 percent to more than 24 percent.

In fact, over 90 percent of all species that ever lived are now extinct. In the last 500 million years, there have been five times 61 life on Earth has almost ended. These include the third mass extinction, 62 (know) as the “Great Dying” which killed 90% to 96% of all species. And the fifth event, which 63 (occur) 66 million years ago, caused the death of the dinosaurs. The reasons for extinctions are 64 (vary). According to scientists, they include volcanic eruptions, asteroids 65 (hit) the Earth from space, changes in sea levels, the decrease of the oxygen content of the sea and global warming. Many scientists say we are now entering the Earth’s sixth mass extinction. This time, human activity will be to blame. Although it is not unusual for species to die out naturally, the rate 66 which this is now happening is cause for concern. A 2015 study by scientists who were based at Brown University and Duke University in the US, looked at how quickly species die out due to natural causes, that is, the “background extinction rate” They found that human activity is causing species to die out 1,000 times faster than normal. There is a long list of reasons why so many species are dying out: air and water pollution, forests being destroyed, factory farming and overfishing. 67 is clear that human activity has 68 (negative) affected all other species on Earth, including animals and plants. If a sixth mass extinction occurs, scientists who have studied the issue believe that up to three quarters of all species on Earth could die out. Of course, as we 69 (human) depend on so many species for our survival, we would also be at risk of dying out. Our world and our lives depend on the balance in nature between animals and plants. Without forests, we would have no air to breathe, 70 without clean water we would be unable to survive.

The tall trees make a canopy (顶篷) of branches and leaves that protect themselves, smaller plants and the forest animals from heavy rain, intense dry heat 73 (release) from the sun and strong winds. 74 (amazing), the trees grow in such a way that their leaves and branches, although close together, never actually touch 75 of another tree. Scientists think this is a deliberate way 76 (prevent) the spread of any tree discases. The ground floor of the forest is not all twisted leaves and bushes, 77 a fairly clear land.

环境保护” 主题中的常见固定搭配和短语,如 “be concerned about”“in harmony with”“be home to” 等牢记于心。在语法填空中,一旦看到相关的提示词或语境,就能迅速反应出应该使用哪个固定搭配。 注意搭配的完整性:在填写固定搭配时,要确保搭配的各个部分都完整、正确。比如 “contribute to” 中的 “to” 是介词,后面要接名词或动名词形式,如果写成 “contribute for” 就是错误的。 4注意语法规则 词形变化:根据语法规则,对高频单词进行正确的词形变化。比如,名词可能需要根据语境变为复数形式,如 “species” 单复数同形,但在表示多个物种时要用 “species”;动词要根据时态、语态和主谓一致等进行变化,如 “Many species are being ___ (threaten) by human activities.” 中,要用 “threatened” 来构成被动语态。 短语的语法功能:了解高频短语在句子中的语法功能,如 “take measures to” 后面要接动词原形,“at risk of” 后面要接名词或动名词等。例如,“We are at risk of ___ (lose) many precious species.” 中,要用 “losing”。 5.检查与验证 整体检查:完成填空后,再次通读全文,检查所填的高频单词和短语是否使文章在语法上正确、语义上通顺、逻辑上连贯。尤其要注意所填内容与上下文的衔接是否自然,有没有出现语法错误或搭配不当的情况。 细节检查:检查单词的拼写是否正确,短语的使用是否符合习惯用法,以及语法形式是否准确。比如,“sustainable” 不要误写成 “sustanable”,“be home to” 中的 “to” 不能遗漏等。 四、高二英语“人与自然 - 环境保护” 主题下语法填空的答题技巧 高二英语 “人与自然 - 环境保护” 主题下的语法填空有一定的答题技巧,涵盖快速浏览、判断词性、分析句子结构、考虑固定搭配等方面,以下具体介绍: 1.快速浏览全文 把握主题方向:迅速浏览文章,确定是聚焦于环境污染现象、环保行动措施,还是人与自然的和谐关系等具体方向。比如文章若围绕森林砍伐展开,可能会涉及 “deforestation” 等相关词汇。 了解大致内容:知晓文章是说明性、议论性还是叙述性,明确文章的整体框架和大致内容,为后续填空建立整体认知。 2.精准判断词性 根据句子成分判断:若空格处在主语或宾语位置,通常需填名词,如 “____ protection is of great importance”,这里就可能填 “Environmental” 对应的名词 “Environment”;若在谓语位置,一般是动词,如 “Humans should ____ (protect) the ecosystem”,需填动词 “protect”;修饰名词用形容词,修饰动词、形容词或其他副词用副词。 依据上下文逻辑判断:根据上下文的语义逻辑来确定词性。如前文说 “Pollution is a serious problem”,后文提到 “it affects our life ____”,根据逻辑这里需要一个副词来修饰 “affects”,可能填 “seriously”。 3.仔细分析句子结构 确定从句类型:若句子中有从句,要判断是定语从句、名词性从句还是状语从句等,然后根据不同从句的特点来填空。比如 “The place ____ we live is facing environmental problems”,这里是定语从句,先行词是 “place”,在从句中作地点状语,所以填 “where”。 注意并列句和复合句:对于并列句,要注意前后句的逻辑关系和时态一致性;复合句要注意主从句之间的关系和时态搭配。例如 “And” 连接的并列句,前后句的时态和结构通常保持一致。 4.考虑固定搭配与习惯用法 短语搭配:牢记 “人与自然 - 环境保护” 主题相关的固定短语,如 “be harmful to”“in favor of”“make a contribution to” 等,根据语境准确运用。如 “He is always ____ favor of environmental protection activities”,应填 “in”。 习惯用法:注意一些单词的习惯用法,如 “it is + adj. + to do sth.” 结构,“It is necessary ____ (take) action to protect the environment”,就需要填 “to take”。 5.关注语法规则与特殊情况 时态和语态:根据上下文语境和时间状语来确定时态,同时注意主被动语态。如 “Many trees ____ (cut) down every year”,根据 “every year” 可知用一般现在时,“trees” 和 “cut” 是被动关系,所以填 “are cut”。 主谓一致:确保主语和谓语在人称和数上保持一致。如 “The environment, together with all the living things in it, ____ (need) our protection”,这里的主语是 “The environment”,是单数,所以填 “needs”。 词性转换特殊情况:有些单词的词性转换有特殊规则,如 “pollute” 的名词形式是 “pollution”,形容词形式是 “polluted” 或 “polluting”,要准确记忆和运用。 6.检查答案 语法检查:检查所填内容在语法上是否正确,包括词性、时态、语态、主谓一致、从句引导词等是否使用正确。 语义检查:通读全文,确保所填内容使文章语义连贯、逻辑合理,符合 “人与自然 - 环境保护” 的主题。 五、高二英语“人与自然 - 环境保护” 主题下语法填空的考法考点 高二英语 “人与自然 - 环境保护” 主题下的语法填空主要围绕词汇、语法、语篇理解等方面设置考法考点,具体如下: 1.词汇考点 词性转换 常考形容词与名词、动词与名词、形容词与副词之间的转换。例如:“environment”(名词)与 “environmental”(形容词),“pollute”(动词)与 “pollution”(名词),“frequent”(形容词)与 “frequently”(副词)等。要求考生根据句子成分和语境准确判断所需词性并进行正确转换。 固定搭配与短语 涉及与主题相关的大量固定搭配和短语,如 “be concerned about”“contribute to”“in harmony with”“take measures to”“be home to” 等。考查考生对这些搭配和短语的记忆及在语境中的正确运用。 2.语法考点 动词的时态和语态 结合上下文语境,考查一般现在时、一般过去时、现在进行时、现在完成时等时态,以及主动语态和被动语态的用法。例如:“The air quality in the city ____ (improve) in the past few years.” 应填 “has improved”,考查现在完成时。 可能会出现一些表示时间的标志词或根据上下文逻辑来确定时态和语态。 非谓语动词 考查不定式、动名词、分词作主语、宾语、定语、状语等。如 “____ (protect) the environment is our responsibility.” 中,“To protect” 或 “Protecting” 作主语。 要求考生掌握非谓语动词的各种用法及在不同语境中的区别。 3.从句 定语从句:考查关系代词(that, which, who, whom, whose)和关系副词(where, when, why)的用法,如 “I still remember the park ____ we planted trees last year.” 需填 “where”。 名词性从句:包括主语从句、宾语从句、表语从句和同位语从句,考查连接词(that, whether, if, what, who, when, where 等)的选择。 状语从句:考查时间、地点、原因、条件、让步等状语从句的连接词,如 “____ it rains tomorrow, we will still go to pick up rubbish in the park.” 应填 “Even if”。 4.主谓一致 考查主语为单数或复数时,谓语动词的形式变化。如 “Either you or he ____ (be) responsible for the project of environmental protection.” 根据就近原则应填 “is”。 涉及一些特殊情况,如集体名词作主语、由 with, together with 等连接的并列主语等的主谓一致问题。 5.冠词、介词和代词 冠词:考查不定冠词 a/an 和定冠词 the 的用法,如 “____ elephant is a symbol of the natural environment.” 应填 “An”。 介词:考查与主题相关的介词搭配,如 “in, on, at, for, of” 等在不同语境中的用法。 代词:考查人称代词、物主代词、反身代词、不定代词等的用法,如 “Everyone should do ____ (they) part to protect the environment.” 应填 “their”。 6.语篇理解考点 上下文逻辑关系 要求考生根据文章的逻辑关系,填写合适的连接词或过渡词,如 “however”“therefore”“besides”“moreover” 等,使文章语义连贯。 例如:“The government has taken many measures to protect the environment. ____, there is still a long way to go.” 这里应填 “However”,表示转折关系。 词汇复现与语境推断 利用词汇复现(原词复现、同义词复现、反义词复现等)来设置考点,考生需要根据上下文出现的相关词汇来推断空格处的答案。 如前文提到 “pollution”,后文可能会出现 “reduce pollution”“combat pollution” 等相关表达,通过这种联系来考查考生对语境的理解和词汇的运用能力。 六、“人与自然-环境保护”语法填空精练题 (24-25高二上·河南濮阳·期末)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式,并将答案填写在答题卡上。 A wild Siberian tiger 1 (spot) near Changbai Mountain in Northeast China’ s Jilin Province on Tuesday, marking the return of the species 2 the mountain after 30 years.

In fact, over 90 percent of all species that ever lived are now extinct. In the last 500 million years, there have been five times 61 life on Earth has almost ended. These include the third mass extinction, 62 (know) as the “Great Dying” which killed 90% to 96% of all species. And the fifth event, which 63 (occur) 66 million years ago, caused the death of the dinosaurs. The reasons for extinctions are 64 (vary). According to scientists, they include volcanic eruptions, asteroids 65 (hit) the Earth from space, changes in sea levels, the decrease of the oxygen content of the sea and global warming. Many scientists say we are now entering the Earth’s sixth mass extinction. This time, human activity will be to blame. Although it is not unusual for species to die out naturally, the rate 66 which this is now happening is cause for concern. A 2015 study by scientists who were based at Brown University and Duke University in the US, looked at how quickly species die out due to natural causes, that is, the “background extinction rate” They found that human activity is causing species to die out 1,000 times faster than normal. There is a long list of reasons why so many species are dying out: air and water pollution, forests being destroyed, factory farming and overfishing. 67 is clear that human activity has 68 (negative) affected all other species on Earth, including animals and plants. If a sixth mass extinction occurs, scientists who have studied the issue believe that up to three quarters of all species on Earth could die out. Of course, as we 69 (human) depend on so many species for our survival, we would also be at risk of dying out. Our world and our lives depend on the balance in nature between animals and plants. Without forests, we would have no air to breathe, 70 without clean water we would be unable to survive. 【答案】 61.when 62.known 63.occured 64.varied/various 65.hitting 66.at 67.It 68.negatively 69.humans 70.and 【导语】本文是一篇说明文。本文简述了地球物种灭绝的历史与现状,指出人类活动正加速第六次物种大灭绝,并强调了生态平衡对人类生存的重要性。 61.考查定语从句关系词。句意:在过去的5亿年里,地球上生命几乎灭绝过五次。设空处引导定语从句,先行词是five times,在从句中作时间状语,应用关系副词when引导。故填when。 62.考查非谓语动词。句意:其中包括第三次大灭绝,被称为“大灭绝”,90%到96%的物种死亡。句中include为谓语动词,设空处考查非谓语动词,逻辑主语the third mass extinction与know之间为被动关系,应用过去分词known作后置定语。故填known。 63.考查动词时态。句意:第五次事件发生在6600万年前,导致了恐龙的死亡。设空处为从句的谓语动词,根据时间状语66 million years ago可知,句子应用一般过去时。故填occurred。 64.考查形容词。句意:物种灭绝的原因是各种各样的。设空处应填形容词作表语,vary的形容词是varied,意为“各种各样的”,或various,意为“各种各样的”,在句中作表语。故填varied/various。 65.考查非谓语动词。句意:根据科学家的说法,它们包括火山爆发、小行星撞击地球、海平面变化、海洋氧含量减少和全球变暖。设空处考查非谓语动词,asteroids与hit之间为主动关系,应用现在分词hitting作后置定语。故填hitting。 66.考查介词。句意:尽管物种自然灭绝并不罕见,但现在正在发生的灭绝速度却令人担忧。设空处考查介词,rate常与介词at连用,表示“以……速度”,此处构成介词+关系代词引导定语从句的结构。故填at。 67.考查it作形式主语。句意:很明显,人类活动已经对地球上包括动植物在内的所有其他物种产生了负面影响。设空处考查it作形式主语,真正的主语为that引导的从句,it is clear that……为固定句型,意为“很明显……”。同时该空置于句首,开头单词首字母大写。故填It。 68.考查副词。句意:很明显,人类活动已经对地球上包括动植物在内的所有其他物种产生了负面影响。设空处修饰动词affected,应用副词negatively,作状语。故填negatively。 69.考查名词复数。句意:当然,由于我们人类依赖如此多的物种来生存,我们也面临着灭绝的风险。设空处应填名词作主语,根据空后的depend可知,此处应用复数形式humans,表示“人类”。故填humans。 70.考查连词。句意:没有森林,我们就没有空气可呼吸,而没有干净的水,我们就无法生存。设空处前后为并列关系,连接两个介词短语,应用连词and连接。故填and。 (2023高二上·浙江温州·期末)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。 Despite occupying a relatively small area, rainforests have an important role to play in maintaining the world and they are home to a rich 71 (various) of medicinal plants, birds and animals.
