1、英语从句详解第一部分从句（Subordinate Clause）是复合句中不能独立成句，但具有主语部分和谓语部分，由that、who、when 等引导词（Connective）引导的非主句部分。从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句 6 类。前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；后两类定语从句和状语从句功用相当于形容词，称为形容词性从句。状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句。1.主语从句（ Subject Clause）：用作主语的从句叫主语从句。引导主语从句的关联词有从属连
2、词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。2.表语从句（ Predicative Clause）：用作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大都一样。3.宾语从句（ Object Clause）：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。第一部分一.、定义： 宾语从句就是一个句子作动词或介词的宾语。二、学习宾语从句要抓住三要素：连接词、语序和时态。连接词一般都是 that(指事务或人),which （指事）,who（指人） 1从句为陈述句，常选择连接词 that 或将 that 省略，直接与主
3、句相连。 2从句为一般疑问句，常选择连接词 if 或 whether。在 whetheror not 结构中不能用 if替换。 3从句为特殊疑问句，常选择 what,when,where,which,who,how 等的疑问代、副词作连接词。 当 who 为主语时，句式为：who+谓语+其他判断时态情况：1.主句是一般现在时，从句为各种时态情况 2.主句是一般过去时，从句为各种相应过去时态注意：从句描绘客观事实，用一般现在时3.主句是一般将来时，一般从句为一般现在时（“主将从现”）例题：1. The teacher told the children that the sun round.A.
4、 was B. is C. were D. are2. I believe that our team the basketball match.A. win B. won C. will win D. wins3.

5、 D.what;where 答 4：选 B，动词 reach 后接宾语从句，从句缺少宾语， where 不可，which 引导宾语从句时表疑问含义“哪一个”而此句中并非疑问含义，不知道哪一座庙宇，而是用 what 从句表陈述含义，意“过去的一座旧庙宇”；temple 后为对其修饰的定语从句，用关系代词 which代替，并在从句中作动词 used 的宾语，use sth. as“把用作宾语从句，在复合句中作宾语，位于及物动词后； Tell him which class you are in Do you know what he likes？ (1)主、从句时态一致： 主句谓语过去时，从句相应
6、过去时； He answered that he was listening to me. 主句谓语现在时，从句时态任所需； He says (that) he will leave a message on my desk. They know (that) he is working hard. 具体过去永不变，真理格言现在时； He told me that he was born in 1980. Father told me that practice makes perfect . （2）否定前移，及完成反意问句； 在 think / believe / suppose / gue
7、ss / imagine / expect 等动词后跟宾语从句否定式时，应转移到主句上去，完成反意疑问句时，应与从句主、谓保持一致。（注: 否定前移的条件是，主句主语是第一人称） I dont think you are right ,are you ? I dont believe they have finished their work yet,have they ? （3）在表示建议 suggest , advise 要求 demand 、desire、require、request 、propose； 决定 decide; 命令 order、command; 坚决主张 insist;
8、 等动词后跟宾语从句，用（should）+v （虚拟语气） eg I suggested that you（should ）study hard He ordered that we should go out at once （4）如果宾语从句后有宾语补足语，用 it 作形式宾语，把宾语从句后置 egYou may think it strange that he would live there （5）宾语从句 that 常可省略，但在以下情况下不能省略 A当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个 that，其他不能省略。 egI believe（that）you hav
9、e done your best and that things will get bet?鄄 ter B当 it 作形式宾语时 egShe made it clear that she had nothing to do with him C当宾语从句前置时 egThat our team will win，I believe三、分类A 、作动词的宾语:egI heard the newsI 主语 heard 谓语动词 the news.名词作宾语I 主语 heard 谓语动词 that he would come here later on.一个句子作宾语- 宾语从句B 、作介词的宾语:e
10、gHe said nothing about this plan 。He 主语 said 谓语动词 nothing 代词作动词的宾语 about 介词 the plan. 名词作介词的宾语四、带有宾语从句的复合句的构成:带有宾语从句的复合句就是用连接词把一个主句和一个宾语从句连接在一起。连接词有：that(可省略)，what, who, when, where, why, which, if, whether, how.五、注意： A 宾语从句必须用陈述语序。False: He is wondering when can he finish this difficult job.Right:
11、He is wondering when he can finish this difficult job. B 有时候可以用 it 作形式宾语，而把真正的宾语从句放在后面。Bad: I thought that he could finish this job in just two hours impossible.Good: I thought it impossible that he could finish this job in just two hours.

13、g in the corner.4.同位语从句（ Appositive Clause）： 与先行词同位或等同的从句叫作同位语从句。其关联词多为 that。5.定语从句（ Attributive Clause）：用作定语的从句叫定语从句。定语从句一般皆放在被它所修饰的名（代）词之后，这种名（代）词就叫作先行词（Antecedent）。引导定语从句的关联词为关系代词(或称引导词、关系词等）。关系代词在定语从句中可用作主语、宾语、定语等；关系副词在定语从句中用作状语。引导定语从句的关联词有 who, whom, whose, that, when, where, why 和 which. 在非限制定
14、语从句中, 只可用 which, who, whose, where , when., 如果指代前面整个句子, 多用which.例句：The dog that/which was lost has been found. （失踪的狗已经找到了。）Those who are in favor of the proposal are expected to discuss it in detail after the meeting. （有人认为那些对这个提案有兴趣的人最好是在会后再具体讨论它。）There are many organizations whose purpose is to he
