高中英语语法解析---名词性从句

高中英语语法解析---名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses）。

名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

一．主语从句主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it 代替，而本身放在句子末尾。

引导主语从句的连词有：that, whether, who, whom, what, whatever, whose1.常规主语从句，既复合句在句中充当一个主语，那么这个句子就是主语从句(1)That he finished writing the composition in such a short time surprised us all.(2)Whether we will go for an outing tomorrow remains unknown.(3)Who will be our monitor hasn’t been decided yet.(4)Whom we must study for is a question of great importance.(5)What caused the accident remains is unknown.(6)What we need is time.(7)Whose watch was lost is unknown.(8)Whatever you did is right.注：连词位于句首不能省略2. It 作形式主语和it引导强调句的比较（为了防止句子头重脚轻，通常把形式主语it放在主语位置，真正主语搁置于句末）It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。

而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。

一、时间状语从句：引导词有after，before，as，once，since，till，until，when，whenever，while，as soon as，the moment/minute…(一…就)，the time,the day,every time,next time,each time，by the time of，no sooner…than(一…就)，hardly…when(一…就).例如：Each/Every time he comes here,he will drop in on me.每次他来这儿他都顺便看我.He was ill last time I saw him.上次我见到他时他病了.No sooner had she heard the news than she cried.她一听到这个消息就哭了.[辨析]when与whilewhen引导的从句动词可以是延续性的或短暂性的，while引导的从句中动词必须是延续性的;在“be…when…”句式中when表“at that time(就在这时)”意，这样用的when不能换为while;while有时并不表示时间，而表示对比，意“而”、“却”，when无这样的用法。

语法精讲——从句的辨析

一、弄清复句的概念。

复句是指“主句+从句”。

英语中共有：三种从句类型：状语从句，定语从句和名词性从句。

从句的构成：从句的标志词+陈述句。

从句存在的规则：两句并存有且必须有一主一从之分。

标志词的使用规则：两句并存有且仅有一个从句的标志词。

二、了解如下三大从句的功能解析。

定语从句：（整个从句在主句中充当一个定语）构成：the+先行词（被修饰名词）+关系词+陈述句。

如何判断是一个定从：只要主句中有一个名词或整个主句在后面的从句中充当一个逻辑意思成分，该从句即为定语从句。

如何选择关系词：看从句缺少什么成分，指什么。

关系词的功能：who（定从中做主语，指人）whom（定从中做宾语，指人）that（定从中做主/宾语，指人/物）whose（定从中做定语，指人/物）which（定从中做主/宾语，指物）as（整个主句在从句中做主/宾，从句中常含有know/see/expect 的标志，且此定从常可置于主句之前，译为“正如…样”）when（定从中做时间状语）where（定从中做地点状语）why（定从中做原因状语）☆翻译原则：先译定从加“的”再译被修饰名词。

名词性从句：（在一个句子中的名词性成分——主语、表语、宾语、同位语处出现的句子）构成：连词+陈述句分类：主语从句，表语从句，宾语从句，同位语从句。

如何选择连词：只要判断一个从句中缺何成分，指什么。

连词的各个功能如下：that（不做任何成分，没有任何实意，只陈述事实，宾从中可省）who（做主语，指人，译为“谁”）whom（做宾语，指人，译为“谁”）whose（做定语，指人，译为“谁的”）which（做定语，指物，译为“哪一个”、“哪一些”可和of连用表范围指人）what（做主、表宾，指物，译为“什么”或“是…的”）when（做时间状语，译为“何时”）where（做地点状语，译为“哪里”）why（做原因状语，译为“为什么”）how（做方式状语，译为“怎么”“怎样”）if（是否，只用于及物动词的宾从中）whether （是否，可用于一切名从中常和or not 连用）☆翻译原则：是按词序不变。

高中英语从句类型

从句的分类六大从句类型主语从句用作主语.That the earth is round is true.宾语从句用作宾语;Do you know where he lives表语从句用作表语.My opinion is that you should not go alone.同位语从句用于解释说明前面的名词,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;The fact that the earth is round is true.that从句用于解释说明the fact定语从句相当于一个形容词,用于修饰前面的名词;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和关系副词;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;The student who answered the question was John.状语从句相当于一个副词,修饰主句中的动词, 形容词和副词, 通常有从属连词引导, 按其意义和作用可分为时间, 地点, 条件, 原因, 让步, 目的, 结果, 方式, 比较.等When it rains, I usually go to school by bus.If he comes tomorrow, you will see him.He returned home to learn his daughter had just been engaged.You must speak louder so that /in order that you can be heard by all.Since /As the weather is so bad, we have to delay our journey.从句划分技巧主句和从句的划分方法是相同的;句子的成分从谓语动词处来划分比较容易;谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语;定语从句VS同位语从句定语从句是先行词的修饰语,它不涉及先行词的实质内容,在定规从句中“that”往往充当某一成分且作宾语时可以省略;同位语从句是对中心词的内容作进一步的解释和说明,表明中心词语的具体、实际内容;“that”在同位语从句中不充当任何成分且不可以省略;从句划分练习1. It is quite clear that the crime was down deliberately.2. She suggested that he do it at once.3. That the earth is round is true．4. The problem is not who will go but who will stay.5. The student who answered the question was John．6. Have you any idea how soon they’re coming.7. My original question, why he did it at all ,has not been answered.8.

I’ll take whoever wants to g o with me to the theatre.26. The news that he told me was that Tom would go abroad.27. If he comes tomorrow, you will see him．28. The news that Tom would go abroad was told by him.。

考研英语语法(从句)详细解析总结(含例句)

考研英语语法（从句）详细解析总结（含例句）(一)英语从句的原理1.我们已经学习过句子的成分【参考句子成分讲义】当一个完整的句子A成为另一个句子B的某一成分时，A就变成了从句●eg. I know that you are hard-working！我知道你们很努力●完整的句子A { you are hard-working } 就叫做从句，在主句 B [I know A]中作宾语➡️A随从/服从B2.英语的三种句子●简单句：不能再拆分的句子【参考简单句讲义】●复杂句：也叫做并列句，两个句子不分主次，仅仅逻辑关系词连接and、but、however，，，●eg. I like apples，and he likes bananas. = He likes bananas，and I like apples.●复合句：主从复合句，主句 + 从句，两个句子有主次关系(二)英语从句的分类所以有哪些句子成分就会有哪些从句类型：除了英语的核心动词之外，其他所有句子成分都可以有从句1.①形容词从句 = 定语从句 = 关系从句➡️英语从句中最重要的；内容最多的；最难的一类从句●概念●对某个人或者事物进行描述，具有形容词性质➡️形容词性从句●在句子中充当定语这个成分，起修饰作用➡️定语从句●构成往往需要关系词来引导➡️关系从句●形容词从句的思维方式●中文思维：形容词都放在被修饰词之前，即形容词/句子 + 的eg. 好吃的苹果；努力学习的他们●英语思维●单个词修饰时，也放在被修饰词之前eg. a tasty apple●用一句话来修饰时，就需要在被修饰词后面 + 一个与它有关系的词 + 另一个句子，即先行词 + 关系词 + 定语从句●思维对比：这也是我们在翻译时不能逐字逐句顺序进行的原因，定语从句就需要逆序先翻译●中文：兔子在吃一根我买来的胡萝卜【前置】●英语：兔子在吃一根胡萝卜（胡萝卜的关系词）我买的【后置】The rabbit is eating a carrot that I bought.●形容词从句的构成：关系词（引导定语从句）●关系代词：引导词起指代、替代的作用●方法：陈述句语序中，被修饰词更换为关系代词➡️把关系代词放到开头，就变成了从句●that（那）：The rabbit is eating a carrot that I bought.I bought that →that I bought●who（主语）：The student who is reading is my friend.who is reading →who is reading●whom（宾语）：The student whom I taught is my friend.I taught whom →whom I taught●whose（ta的）：The student whose bag is pink is my friend.whose bag is pink →whose bag is pink●which（那个）：The student which is reading/I taught is my friend.which is reading/I taught which →which is reading/I taught●that & which：指代人或物（主语宾语都可以），经常可以互换●先行词唯一：that●eg. The rabbit ate the biggest carrot that I 've ever seen. 兔子吃了我见过最大的胡萝卜●the biggest已经限定了先行词是唯一的，所以只能用that●先行词多选一：which●eg. The rabbit is eating a carrot that/which I bought.●我买了很多根胡萝卜，兔子吃的只是其中随便一根●关系副词：引导词的词性是副词关系副词 = 介词 + 关系代词●where（地点）：This is the place where I study.●why（原因）：This is the reasin why I study.●when（时间）：That was the day when I met him.●形容词从句的限定性和非限定性●通过前面的学习，大家已经明白了定语从句的主要功能就是修饰限定范围，所以限定性和非限定性的区别即：是否限定了先行词的范围/性质●限定性定语从句●上述例句均为限定性定语从句：全部都限制了先行词的范围●非限定性定语从句：通常有逗号隔开，作插入语补充信息●eg. I read the book，which is on the desk. 我读了本书，那本书在桌子上（有种接着说，补充说明的意思）●eg. My head，which is big，is useful when it rains. 我有大头下雨不愁（作插入语补充信息，即使删去也不影响原句子完整）●eg. Rabbits eat carrots， which is not surprising. 兔子吃胡萝卜，这事不稀奇（甚至可以指代一个完整的句子进行修饰）2.②名词从句●引导词：相当于一个信号告诉你“那么接下来从句要开始咯！”注意：引导词在从句开头；从句是陈述句语序●that：确定信息●whether；where；when；how；who；what：不确定信息●主语从句：将句子中的主语变成从句的形式●正常语序：主语放在句子最开头●eg. That rabbits eat carrots is obvious.●eg. Whether rabbits eat carrots is obvious. 是否吃●eg. Where rabbits eat carrots is obvious. 在哪吃●eg. When rabbits eat carrots is obvious. 什么时候吃●eg. Who eats carrots is obvious. 谁吃●eg. What rabbits eat is obvious. 吃什么●eg. How rabbits eat carrots is obvious. 怎么吃●形式主语：it指代主语从句，it本身没有什么意义【翻译时，可以拆成两句或是倒序先翻译主语从句】英语句子的主语从句过长就会头重脚轻，所以会改个形式说出来●eg. It is obvious that rabbits eat carrots. 很明显，兔子吃胡萝卜/兔子吃胡萝卜这事儿很明显●eg. It is obvious whether rabbits eat carrots.●可自行练习改写上述例句●表语从句：将句子的表语变成从句的形式●eg. The reason is that you need to study.●eg. It feels that you like me.●同位语从句：将句子的同位语变成从句的形式●一般修饰抽象名词：the fact；the idea...●eg. The question that/whether rabbits eat carrots is interesting.●宾语从句：从句作句子的宾语●确定信息&不确定信息●eg.
