(to) do sth. — to可以省略也可以保留，高考两种形式都认可。 【翻译技巧】 并列谓语结构（made...and encouraged...）翻译时注意层次。make译为"让/使"，encourage译为"鼓励"。 【参考译文】 这部纪录片让我们认识到人类活动对环境造成的巨大损害，并鼓励我们立即采取行动保护我们称之为家园的地球。 【名师点睛】 ⭐ 主动省to，被动加to——make/let/have+宾语+do（主动省略），但被动时：be made to do（to必须恢复）！ —————————————————————————————————————————————————— 第4句 No.4 | 难度系数：★★★☆☆ | 来源：2021年全国乙卷 阅读理解D篇 【原句】 We can do nothing but take immediate action to reduce carbon emissions before it is too late to reverse the damage that has already been done to the ecosystem. 【核心词汇】 词汇 音标 词性 释义与搭配 emission /ɪˈmɪʃ(ə)n/ n. n. 排放物。carbon emissions 碳排放。例：The government plans to cut carbon emissions. reverse /rɪˈvɜːs/ v. v. 逆转。reverse the damage 扭转破坏。例：It is difficult to reverse the damage. ecosystem /ˈiːkəʊsɪstəm/ n. n. 生态系统。damage to the ecosystem 对生态系统的破坏。例：The ecosystem has been severely damaged. 【句子解剖】 [主句] We can do nothing but take immediate action to reduce carbon emissions ├── 主语：we ├── 谓语：can do ├── 宾语：nothing └── 例外：but take（but = except，前面有do所以省略to） [时间状语从句] before it is too late to reverse the damage └── 结果状语：too late to reverse（太……以致不能……） └── [定语从句] that has already been done to the ecosystem（修饰the damage） 【语法精讲】 一、"do nothing but + 动词原形"结构 当but/except前面有实义动词do时，后面的不定式省略to： - ✅ We could do nothing but wait.（前面有do，省略to） - ✅ We had no choice but to wait.（前面没有do，保留to） - ❌ We had no choice but wait.（前面无实义动词do，to不能省略） 二、before it is too late句型 "在太晚之前做某事"= 趁还来得及做某事。 【翻译技巧】 do nothing but do结构翻译为"只能做……"。before it is too late译为"趁还来得及"。 【参考译文】 我们别无选择，只能立即采取行动减少碳排放，趁现在弥补对生态系统造成的损害还为时未晚。 【名师点睛】 ⭐ 前面有do，后面省to；前面无do，保留to——判断but后用动词原形还是不定式，就看前面有没有do！ —————————————————————————————————————————————————— —————————————————————————————————————————————————— 📅 Day 43：插入语的类型与功能 插入语是插入在句子中间、对句子内容进行补充说明的词语或短语，通常用逗号隔开。 —————————————————————————————————————————————————— 第5句 No.5 | 难度系数：★★★☆☆ | 来源：2022年全国乙卷 阅读理解C篇 【原句】 The key to achieving sustainable development, in the opinion of many leading environmental experts, lies not in technological innovation alone, but rather in a fundamental change in the way we consume resources and manage waste. 【核心词汇】 词汇 音标 词性 释义与搭配 sustainable /səˈsteɪnəb(ə)l/ （见搭配） adj. 可持续的。sustainable development 可持续发展。例：We need sustainable solutions. leading /ˈliːdɪŋ/ （见搭配） adj. 领先的。leading expert 权威专家。例：She is a leading figure in the field. innovation /ˌɪnəˈveɪʃ(ə)n/ n. n. 创新。technological innovation 技术创新。例：Innovation drives economic growth. fundamental /ˌfʌndəˈment(ə)l/ （见搭配） adj. 根本的。a fundamental change 根本性变化。例：There needs to be a fundamental change. 【句子解剖】 [主句] The key to achieving sustainable development ... lies ... in a fundamental change ├── 主语：The key to achieving sustainable development ├── 插入语：, in the opinion of many leading environmental experts,（介词短语作插入语） ├── 谓语：lies ├── 否定状语：not in technological innovation alone └── 并列状语：but rather in a fundamental change └── in the way we consume resources and manage waste（the way后定语从句省略关系词） 【语法精讲】 一、插入语的识别 插入语位于主语和谓语之间，用逗号隔开。阅读时先跳过插入语，直接连接主谓： The key...lies...in a fundamental change. 常见插入语类型： - 副词：however, therefore, indeed - 介词短语：in my opinion, as a result, in other words - 句子：I believe, you know, experts say 二、not...but rather...结构 "不是……而是……"，连接两个并列的状语： - not in technological innovation alone - but rather in a fundamental change 三、way作先行词的定语从句 - the way in which we consume（最正式） - the way that we consume（较常用） - the way 不填 we consume（最常用） 【翻译技巧】 插入语"in the opinion of..."译为"在……看来"放到句首最自然。 【参考译文】 在众多权威环境专家看来，实现可持续发展的关键不仅在于技术创新，更在于我们对资源消耗和废物管理方式的根本性改变。 【名师点睛】 ⭐ 阅读中遇到插入语，先用括号框出插入部分，再读主干。题目问核心观点时，答案就在去掉插入语后的主干中！ —————————————————————————————————————————————————— 第6句 No.6 | 难度系数：★★★★☆ | 来源：2021年新高考I卷 阅读理解D篇 【原句】 The concept of emotional intelligence, which was first introduced by psychologists in the 1990s and has since become one of the most influential ideas in modern psychology, refers to the ability to recognize, understand, and manage our own emotions as well as those of others. 【核心词汇】 词汇 音标 词性 释义与搭配 concept /ˈkɒnsept/ n. n. 概念。the concept of ……的概念。例：This concept is difficult to understand. emotional /ɪˈməʊʃən(ə)l/ （见搭配） adj. 情感的。emotional intelligence 情商。例：Emotional health is important. influential /ˌɪnfluˈenʃ(ə)l/ （见搭配） adj. 有影响力的。influential idea 有影响力的观点。例：He is one of the most influential figures. 【句子解剖】 [主句] The concept of emotional intelligence ... refers to the ability to recognize, understand, and manage our own emotions as well as those of others ├── 主语：The concept of emotional intelligence ├── [非限制性定语从句作插入语] , which was first introduced by psychologists in the 1990s and has since become one of the most influential ideas in modern psychology, │ ├── 从句1：which was first introduced by psychologists in the 1990s │ └── 从句2：and (which) has since become one of the most influential ideas ├── 谓语：refers to └── 宾语：the ability to recognize, understand, and manage our own emotions as well as those of others 【语法精讲】 一、定语从句作插入语 "主语 + ,定语从句, + 谓语"是高考阅读高频结构。阅读时可以先跳过定语从句，找到谓语动词。 The concept..., refers to... 二、定语从句中并列谓语 - was first introduced（一般过去时：被首次提出） - has since become（现在完成时：此后成为） 注意时态变化：从"过去被提出"到"至今仍然有影响力"。 三、as well as与those的替代 - as well as连接：our own emotions 和 those of others - those = emotions（避免重复） 【翻译技巧】 定语从句作插入语可以译成独立句，也可以用"的"前置（如果不太长）。本句由于定语从句较长，适合拆译。 【参考译文】 情商的概念指的是识别、理解和管理我们自己以及他人情绪的能力，这一概念最早由心理学家在20世纪90年代提出，此后已成为现代心理学中最具影响力的思想之一。 【名师点睛】 ⭐ "主语 + ,定从, + 谓语"——先跳过定从找谓语，这是阅读长难句的核心技能！ —————————————————————————————————————————————————— —————————————————————————————————————————————————— 📅 Day 44：省略句在交际与复杂句中的运用 —————————————————————————————————————————————————— 第7句 No.7 | 难度系数：★★★★☆ | 来源：2020年新高考I卷 阅读理解D篇 【原句】 Some scientists believe that climate change will lead to more extreme weather events, while others argue that it will not, and that the current concerns are largely based on incomplete data and overly pessimistic predictions. 【核心词汇】 词汇 音标 词性 释义与搭配 extreme /ɪkˈstriːm/ （见搭配） adj. 极端的。extreme weather 极端天气。例：Extreme weather is becoming more common. argue /ˈɑːɡjuː/ v. v. 主张，争论。argue that... 主张……。例：Some argue that the policy is unnecessary. largely /ˈlɑːdʒli/ （见搭配） adv. 很大程度上。largely based on 主要基于。例：The decision was largely based on cost. pessimistic /ˌpesɪˈmɪstɪk/ （见搭配） adj. 悲观的。pessimistic about 对……悲观。例：He is pessimistic about the future. 【句子解剖】 [主句] Some scientists believe that ... , while others argue that ... , and that ... ├── 第一部分：Some scientists believe that climate change will lead to more extreme weather events ├── 转折并列：while（然而——表示对比） │ └── 第二部分：others argue that it will not (lead to more extreme weather events), and that the current concerns are largely based on incomplete data ├── 主语：others ├── 谓语：argue ├── 宾语从句1：that it will not（省略了lead to more extreme weather events） └── 宾语从句2：and that the current concerns are largely based on incomplete data and pessimistic predictions 【语法精讲】 一、while表示对比 本句中的while不表时间，而表对比"而，然而"： while含义 用法 示例 当……时 时间从句 While reading, I fell asleep. 然而 并列对比（本句） I like tea while she likes coffee. 虽然 让步从句 While I agree, I have doubts. 二、并列句中的省略 "it will not"后面省略了与前面相同的"lead to more extreme weather events"，避免重复。 完整：it will not lead to more extreme weather events 省略：it will not 三、argue后接两个并列宾语从句 argue后面接了两个that从句，由and连接： 1. that it will not（含省略） 2. and that the current concerns are largely based on incomplete data 【翻译技巧】 while表示对比译为"而/然而"。省略部分翻译时需要补充："it will not"译为"不会(导致)"。 【参考译文】 一些科学家认为气候变化将导致更多的极端天气事件，而另一些科学家则认为不会，并且认为目前的担忧主要基于不完整的数据和过于悲观的预测。 【名师点睛】 ⭐ while在阅读中有三种含义：时间"当……时"、对比"然而"、让步"虽然"。判断方法：看前后是同时发生、相反还是矛盾！ —————————————————————————————————————————————————— 第8句 No.8 | 难度系数：★★★☆☆ | 来源：2019年全国卷II 阅读理解C篇 【原句】 The researchers asked whether the participants would continue to support the program if they knew the true cost, and the majority responded that they would, although some expressed concern about the long-term financial implications. 【核心词汇】 词汇 音标 词性 释义与搭配 participant /pɑːˈtɪsɪpənt/ n. n. 参与者。research participant 研究参与者。例：All participants were interviewed. respond /rɪˈspɒnd/ v. v. 回应。respond that... 回答说……。例：She responded that she would help. majority /məˈdʒɒrəti/ n. n. 大多数。the majority of ……的大多数。例：The majority of people agree. implication /ˌɪmplɪˈkeɪʃ(ə)n/ n. n. 影响，含义。financial implications 财务影响。例：The policy has serious financial implications. 【句子解剖】 [第一分句] The researchers asked whether the participants would continue to support the program if they knew the true cost └── [宾语从句] whether the participants would continue to support the program if they knew the true cost └── [条件状语从句] if they knew the true cost（虚拟语气） [并列连词] and [第二分句] the majority responded that they would (continue to support the program if they knew the true cost) └── [宾语从句] that they would（省略了continue to support the program...） └── [让步状语从句] although some expressed concern about the long-term financial implications 【语法精讲】 一、will/do的替代省略 英语中常用助动词替代前文出现过的整个谓语部分，避免重复： -
