英语从句大全-Ppt
• 考点一：主语从句：主要考查主语从句的引导 词；主句的谓语动词，一般用单数。 • 1）It is well-known that the earth moves around the sun. 众所周知，地球围绕太阳转。 （说明：由连词that引导的主语从句，在大多 数情况下用代词it作形式主语。） • 2）Whether we will hold a party in the open air tomorrow depends on the weather. 我们 明天是否在户外开晚会要视天气而定。（此时 不能用if引导主语从句，只能用whether。） • 3）When the sports meet will be held is not decided. 何时举行运动会还没有决定。 • 4）Which car you will choose to buy makes no difference. • 你决定买哪一辆车都不会有任何区别
• 如： • 1）We heard the news that he had won the game. 我们听到消息他赢得了 比赛。 试比较： • 2）We heard the news that he had told her. 我们听到他对她说的消息。 （定语从句） • 例2中的that从句的作用相当于一个形 容词，其作用是修饰the news；例1中 的that从句的作用相当于一个名词， 是对the news的进一步说明。 • 有时如果主句的谓语动词较短，为保 持句子平衡，避免头重脚轻，同位语 从句也常与要说明的名词分开。例如： Word came that he died yesterday. 消息传来说他昨天死了。
• 考点三：表语从句：be动词或者系动词 后面跟主语补足语。 • 1）The question is whether the book is worth reading at all.（问题是这本书 是否值得一读。） 2）That is why we don't like it. • 考点四：同位语从句 • 同位语从句的特点是由一个抽象名词 +that从句构成，引导词一般是that, 而 且that在从句中不充当任何成分。这些 抽象名词有：news, idea, fact, doubt, evidence, promise, rumor, hope, truth, belief, message等，同位语从句是对抽 象名词进行说明解释。

英语中的从句—名词性从句
名词性从句定性
名词性从句顾名思义在句子中起到名词成为的一部分句 子。名词在句子中可以担任主、宾、表、同位语。 在一个句子中从句占据的位置不同就是不同从句，比如 占据主语的位置就是主语从句，占据了宾语就是宾语从 句。
英语中的从句—名词性从句
引导名词性从句的关联词 从属连词 that\ whether \if\as\as if（只有连接的 功能，不充当语法成分） 连接代指词who、whom、which、what、 whose和wh+ever 连接副词where、when、why、how
如何使用关系代词和关系副词 1、看句子中的谓语动词。VT（及物动词）后无宾语，就必须用关系代词，不及物动 词若缺少介词，则必须用关系副词。 e.g. This is the town where i stayed before.
This is the town at which i stayed before. This is the town which i visited before. 2、看先行词在后面的从句子中做什么成分，来选择正确的关系词。如果先行词在后 面的从句中缺少定冠词，还需在关系词前补足定冠词。 e.g. Is this the museum which you visited yesterday. Is this museum the one you visited yesterday. This is the museum where i went yesterday
The fact surprised us.
英语中的名词性从句
whether和if常用来引导宾语从句，这时两者的含义 区别很小，一般可通用,但在以下情况下if不可替代 whether。 a、whether引导的主语从句并在句首 b、引导表语从句 eg The question is whether he will love me. c、whether从句做介词宾语 eg It depends on whether he is ready d、从句后有“or not” e、在及物运动discuss后的宾语从句中，只能用 whether f、在不定式前用whether.eg I don't know whether to go
不可省略的连词：1、介词加连词2、引导主语 从句和同位语从句的连词不可省略。e.g.
That he was graduated made his us happy. we heard the news that our team lost the game.
名词性从句定性——主语从句
主语从句定义：在句子中充当主的成分的句子 结构：（关联词+简单句 ）+谓语+宾语 e.g. 1、who will win doesn’t matter。 2、IT做形式主语时主语从句放最后 It doesn't matter whether he will win or not. 3、that 引导的主语从句时，that 不能省略 That he failed the exam surprised us.
名词性从句定性——表语从句
表语从句定义：在句子中充当表语的成分的句子 结构：系动词be\seem\look+关联词+简单句 e.g. The trouble is that we lost the way. It looks as if it is going to snow.
引导表语从句时的连接词that 可以省略 The trouble is （that） we lo句因与先行词的关系密切,所以不可以用逗号将其与主句隔开; 而非限制性定语从句与先行词之间用逗号将其与主句隔开。 2、非限制性定语从句的先行词可以为整个主句,关联词为 which 不能用that。
As和which引导的非限制性定语从句 由As和which引导的非限制性定语从句，as一般放在句首，which放在句中。 e.g. As is known to all,smoking is harmful to one's health. Smoking is harmful to one's health,which is a well-known theory.
先行词与关系词二合一
anyone who =whoever all that= what=the thing which whatever=anything who=the person/one that whoever=anyone who
THAT不可省略的情况
1、that引导的宾语从句作动词的宾语时，如果动词的后面有几个并列that引导 的宾语从句，这时只有紧挨着动词的第一个that可以省略，其他的that都不可 以省略 e.g. I knew （that）the meeting was important and that my friends wanted to attend it very much.
名词性从句定性—同位语从句
同位语从句作某些特定名词的同位语，(也可以人为是该名词的 进一步说明)这些特定名词有 news,suggestion,question,thought,Idea,opinion,plan,fact,truth, promise,belief,doubt,wish,hope The fact that he came back surprised us 标记成黄色的就是同 位语从句 如何判断是同位语从句 把名词后的连接词及后面句子去掉依然 可以组成一个完整的句子 例如上句
形容词性从句（定语从句）
定语从句（attributive clause）在句子中充当定语修饰一个名词或代词，被 修饰的称为先行词
定语从句结构：先行词+关系代词/关系副词+修饰内容 关系代词：who，whom,whose,that,which 关系副词：when，where，why
形容词性从句（定语从句）
3、如果宾语从句原来是特殊疑问句，只需用原来的特殊疑问词引导 e.g. could you me where to go/why you are late again/when to leave
4、否定转移，将think,believe，suppose，expect，imagine等后面的 宾语从句的否定转移到主句。 e.g. I don't think that he could arrive on time.
2、如果主句的谓语和宾语从句之间有插入语或主句的状语时，引导宾语从句 的that不能省略 e.g. I realized at once that I noticed,for the first time,that our teacher was my brother's classmate.
3、动词后面的宾语如果是双宾语，即间接宾语+直接宾语结构，其中直接宾 语由that引导的宾语从句来充当。这时候that不能省略 e.g. My teacher told me that i should.....
引导词THAT与WHICH的区别
1、不能用that的情况 在引导非限制性定语从句
2、只能用that的作为关系代词 there be 结构中只能用 that，不用which 在不定词如anything,nothing,the one,all,much,few,any,little做先行词。 先行词中有the only和the very修饰时，只用that 先行词为序数、数词、形容词最高级时，只用that 先行词中是人和物的混合
4、如果关系代词（that、which、who）后面直接跟的是动词，则关系代词做 主语，即不可省略。如果不是动词，那么可以直接省略
THAT不可省略的情况
5、当为了强调而把that引导的主语从句位于句首时,that不可省略 e.g. That i would take the job was very clear.
状语从句（ADVERBIAL CLAUSE）
定义：在复合句中做状语成分的从句称为状语从句 分类：时间、地点、原因、目的、结果、条件、方式、比较、让步
时间状语从句
引导词：when,whenever,as,while,after,before,since,ever since,as soon as,once,until,the minute，till，until
时间状语从句
till 和until表示到...为止 • 句首中要用until • Not until 为固定搭配，且放在句首时主句要倒装 e.g. Not until he worked did he realize how hard the life is.
名词性从句定性——宾语从句
宾语从句定义：在句子中充当宾语的成分的句子 结构：主语+谓语+（关联词+简单句 ）
1、当由陈述句充当宾语从句时，用that引导，that无词义，在口语或 非正式文体中常省略。eg He said that he could finish his work on time
2、当由一般疑问句充当宾语从句时，用if或whether引导.
6、当that宾语从句前有 it作其形式宾语时,that不可省略。 e.g.We think it is important that college students should learn hard.
7、that引导的宾语从句放在except,but等介词后面的时候,that不能省略
8、在直接引语中,that引导的宾语从句与主句隔开的时候,that不能省略 My boss is unsatisfied with your work,he said,'that you are not the suitable person for the work.'
