基本含义 被动语态中主语是动作的承受者，表意上呈现出被…"的语义待征，和主动语态主语为动作发出者的逻辑完全相反 核心定义 被动语态的通用基础结构为be动词加过去分词，其中b动词需要根据句子的时态、主语的人称和数的变化进行相应的调整 基础结构 该结构是所有时态被动语态构成的核心基础，不同时态的被动形式都是在这个基础结构上对b动词进行时态变化衍生而来的 一般现在时被动语态的结构为am/is/are加过去分词，常用于描述客观存在的事实、习惯性的被动动作等内容 一般现在时被动 English is spoken all over the world,清晰表达了英语被全世界使用这一客观事实 般过去时被动语态的结构为was/were加过去分词，多用于描述过去发生的被动动作，说明过去某个事物被施加了某类行为 基础时态结构 一般过去时被动 The bridge was built last year,准确表述了这座桥在去年被建造完成的过去发生的事件 般将来时被动语态有两种常用结构，分别是wl be加过去分词，以及ams/are going to be加过去分词，用于描述未来将会发生的被动动作 被动语态基础 一般将来时被动 Aew hospital will be built next year,.说明了新医院明年将会被建造的未来计划 肯定句式 被动语态肯定句的结构为主语加6e动词加过去分词，直接说明主语被施加了某一动作，语义表述直接明确 句式变化规则 否定句式 被动语态否定句的结构为主语加be动词加ot加过去分词，用于否定主语被施加了某一动作，表达相反的语义 疑问句式 被动语态一般疑问句的结构为b动词加主语加过去分词，用于询问主语是否被施加了某一动作，常用于信息确认场景 不及物动词规则 happen、take place、appear、.rise等不及物动词本身就没有被动形式，使用时不能强行套用被动语态结构 短语动词规则 短语动词在转换为被动语态的时候，其后搭智的介词或者副词不能随意丢弃，需要保留在过去分词之后保证语义完整 高频考点汇总 make被动规则 主动语态中make后接不带to的不定式作宾语补足语，转换为被动语态时必须还原不定式符号to,保证结构正确 by的使用规则 by在被动语态中用于引出动作的实际执行者，如果句子不需要强调动作执行者的时候，by和后面的执行者内容可以直接省略 形容词比较级主要用于两者之间的性质、特征等方面的比较，句子中常和tha搭配使用，明确比较的对象 基本用法 适用场景 结构：A+be+比较级+han+B 普通词变化 一般情况下形容词直接在词尾加-er即可构成比较级，例如tall变为taller、.shorts变为shorter都属于这类常规变化 以e结尾词变化 以不发音的e结尾的形容词，构成比校级时只需要在词尾加-r即可，比如nice变为nicer,.late变为ater都符合该变化规则 重读闭音节目末尾只有一个辅音字母的形容词，需要先双写末尾的辅音字母，再加-er构成比较级，比如big变为big9er、thin变为thinner、.hot变为 规则变化 重读闭音节词变化 hotteri都是这类变化 铺音加y结尾词变化 以辅音字母加y结尾的形容词，需要先把y变为i,再加-er构成比较级，例如happy变为happier、easy变为easier、busy变为busier都符合该规则 多音节词和部分双音节形容词，构成批较级时不需要改变词形，直接在词前加more即可，比如beautiful3变为more beautiful,.interesting?变为more 多音节词变化 interesting、expensive变为more expensive都属于这类变化 综合复习川 形容词比较级 good和wel的比较级都是better,bad和ll的l比较级都是worse,many和much的比较级都是more,itte的比较级是less,far的比较级有ifarther和 不规则变化 常见特殊变化 turther两种形式 基础比较句型 比较级加than是最基础的比校句型，用于直接对比两者的差异，例句He is older than me就直接说明了他和我之间的年龄差异 形容词比较级可以用much、even、far、alot等词修饰，用来加深比较的程度，但是vey不能用来修饰t比较级 修饰词搭配句型 This book is much more interesting than that one. 重点句型 the加比较级，the加比较级的结构用于表示越，，越，的递进逻辑，前后两部分分别对应变化的条件和结果 越越.句型 The more you read,the better you will be. 同一范围内进行比较时，需要使用比较级加any other加单数名词的结构，避免把主语自身纳入比较范围导致逻辑错误 同范围比较句型 Shanghai is bigger than any other city in China. 最高级拓展 基本用法 形容词最高级用于三者或三者以上的人或事物之间的比较，结构为the加形容词最高级，句子中常出现in、of.among等表示范围的标志词 条件状语从句常见的引导词有和unless,核心语法规则是主将从现”，即主句使用一般将来时，从句使用一般现在时来表示将来的情况 If it rains tomorrow,we will stay at home. 条件状语从句 引导词与规则 Unless you try hard,you won't succeed. 时间状语从句的常见引导词有when、while、.before,.ater、Unti、as soon as等，多数情况下也遵循主将从现的语法规则 引导词与规则 I will call you as soon as I arrive. 时间状语从句 wh引导时间状语从句时，既可以指时间点也可以指时间段，从句的动词可以是短暂性动词也可以是延续性动词 when与while区别 while引导时间状语从句时，通常指-段时间，从句的动词多为延续性动词，且常用进行时态，例句While I was reading,my mother came back就 体现了该用法特点 原因状语从句的常见引导词有because,since、as、for,用于说明主句动作发生的原因，其中because的语气最强，多用于回答why的提问 原因状语从句 引导词与规则 需要注意的是，because和so不能在同一个句子中同时使用，避免出现连词重复的语法错误 状语从句 让步状语从句的常见引导词是although和though,用于表达虽然..但是..的转折语义，引出和主句逻辑相反的前提条件 让步状语从句 引导词与规则 需要注意的是，although和hough不能和but在同一个句子中同时使用，避免连词使用错误 结果状语从句常用so.that.、sUch.hat引导，表达如此.以至于…的逻辑，so后面接形容词或者副词，sUch后面接名词短语，that后面接 表示结果的从句 He was so tired that he fell asleep immediately 结果状语从句引导词与规则 Mike is such an honest worker that we all believe him. 比较状语从句常用as.as.:not so/asas.:the same.as....than引导，表达比较的从句 比较状语从句 引导词与规则 He works as hard as everyone else(does)in the class. 目的状语从句常用so that,.in order thats引导，表达目的的从句 目的状语从句 引导词与规则 I am studying hard so that/in order that I can enter a famous university.

Right at the gate, I remembered that my house didn’t have gas but only electricity! I felt really stupid and started heading back home 60 what the noise was. In the street, I saw a lost-and-found notice about a monkey 61 ran out of the City Safari Zoo last night. When I got home, I heard 62 funny noise again. I held 63 breath and opened the door slowly. Guess what? I saw the monkey in my cupboard! As it looked 64 , I fed it with a banana and then I drove it to the zoo. The zookeepers were really pleased that it 65 back and gave me a reward of $50!
