高三英语语法教案：从句

高三英语语法教案：从句分类说明 英语中从句分为名词性从句、定语从句及状语从句。从句的语序必须是陈述语序。 一名词性从句：名词性从句分为主语从旬、宾语从句、表语从旬及同位语从句。 引导词：连接代词what，who，whom，whose，which，wh- ever；连接副词when，where，why，how，that，if，whether。 what，who，whom，whose，which，when，where，why，how，if，whether等引导的从句往往含有质疑或疑问；而that引导的从句表示一种事实或陈述的内容。 1主语从句：在主语从句中，that不能省略，若从句在句首，从句不能用if引导。为了避免由于主语从句过长而引起的头重脚轻，常用It作形式主语，而将主语从句移到句子末尾。 2宾语从句：从句的引导词that可省略，从句的时态必须与主句的时态保持一致。 3表语从句：从句中的引导词that一般不能省略，但当主句中含有动词do的各种形式时，that可以省略。 4同位语从句：引导词that不能省略，同位语从句与前面的名词之间是表述或说明的关系，而不存在修饰关系。因此，在名词与从句之间若加be动词，句子的意思成立。 二定语从句：定语从句分为限制性定语从句和非限制性定语从句。 1限制性定语从句：对先行词进行限制或修饰。 先行词：名词或代词 引导词：关系代词which，that，who，whose，whom，as；关系副词when，where，how，why 2非限制性定语从句：对先行词进行补充或说明。 先行词：名词、代词或整个句子 引导词：关系代词which，who，whose，whom，as；关系副词when，where 3注意事项： (1)引导词的选用：引导词既可引导两个句子，又可在从句中充当一定的成分。 在限制性定语从句中，which只能指事、物；that，whose既可指物也可指人：who，whom只能指人；as一般与such，the same，SO连用；but的先行词一般为否定词或否定词所修饰的词。when，where，how，why分别指时间、地点、方式及原因状语。主、从句之间不用逗号分开。 在非限制性定语从句中，which只能指事、物或整个句子的内容；whose既可指物也两指人；who，whom只能指人；as只用来指整个句子的内容。主、从句之间一般用逗号隔开。 在非限制性定语从句中，which，as两个单词都可用来指整个句子的内容，但它们的区别在于： A位置：which所引导的定语从句只能在主句之后；而as所引导的句子既可在主句之后，也可在主句之前。 B意义：which所引导的从句既可为积极的意义也可为消极的意义；as所引导的从句一般只能为积极的意义。此外，which一般指主句本身；而as还用来表示“对照”的意义，意思为“就像一样”。 (2)从句中的谓语形式：一般说来，从句的谓语形式由先行词确定，但当先行词为 one of +n(p1)且one前面有形容词修饰时，从句的谓语动词的形式由one确定。 (3)定语从句与同位语从句、状语从句、强调句的区别。 三状语从句：状语从句分为时间、地点、原因、条件、让步、结果、目的、方式及比较状语从句。 1特征： (1)时间状语从句：连接词when，while，as，before，after，as soon as，till，until, notuntil，the moment，immediately，the firstsecondlast time，instantlyhardlywhen, seldomwhenno soonerthan (2)地点状语从句：连接词where (3)原因状语从句：连接词because，sinceas (4)条件状语从句：连接词if，unless，now(that)，providedproviding (5)让步状语从句：连接词although，though，as，no matter wh-，wh- ever (6)结果状语从句：连接词so，so that，so as that，that (7)目的状语从句：连接词so that，in case，for fear that，lest (8)方式状语从句：连接词how (9)比较状语从句：连接词than，assoas 2注意事项： (1)时间、条件状语从句的时态一致性：当主句为将来时，从句只能用一般现在时。 (2)because不能与SO连用；althoughthough不能与but连用，但可跟yet连用。 (3)though，as(只用于倒装)倒装可数名词是单数时，名词前面的不定冠词应省略。 (4)状语从句的句子结构完整，若不完整就可能是定语从句。 回放真题 真题1(2020甘肃、青海卷24) There are altogether eleven books on the shelf，_five are mine Aon which Bin which Cof which Dfrom which 【答案及解析】 C定语从句只修饰先行词币的一部分，答案选c，of表示部分与整体之间的关系。 真题2(2020甘肃、青海卷27) The road is covered with snowI cant understand _they insist on going by motorbike Awhy Bwhether Cwhen Dhow 【答案及解析】A根据句意，冰雪封路，而他们还坚持乘摩托车，“我”不能明白的显然是原因，因此答案选A。 真题3(2020重庆卷21) You can eat food free in my restaurant _you like Awhenever Bwherever CWhatever Dhowever 【答案及解析】 A主句部分不缺主、宾、表等成分，也有具体的地点状语，答案选A。 真题4(2020广东卷23) I have always been honest and straight forward, and it doesnt matter _ Im talking to Awho is it Bwho it is Cit is who Dit is whom 【答案及解析】 B根据句意，应该是强调句型中的强调部分作引导词；根据从句的语序，答案只能选B。 真题5(2020广东卷25) Parents are taught to understand _important education is to their childrens future Athat Bhow Csuch Dso 【答案及解析】 B根据句子的语序可知，宾语从旬中的important作表语提前，从句的引导词只能用how。 真题6(2020湖北卷25) There are two buildings，_stands nearly a hundred feet high Athe larger Bthe larger of them Cthe larger one that Dthe larger of which 【答案及解析】D根据句子结构排除选项A、B，因为逗号不能连接两个独立的句子；根据先行词two buildings可排除C，因为它后面的从句不是用来说明、描述前面的先行词，而是一个名词同位语，故答案选D。 真题7(2020湖北卷27) You should try to get a good nights sleep _much work you have to do A. however B. no matter C. although D. whatever 【答案及解析】A 根据句子结构排除选项B,C,因B后需接特殊疑问词，而C后的句子不能倒装；当名词前有much, many, little, few等修饰时，前面不能用whatever. 真题8(2020湖北卷29) What surprised me was not what he said but _he said it.
