初中语法 主语从句讲解及(完整版)
主语从句：即在复杂句中充当主语成分的句子
例如"That he finished writing the composition in such a short time surprised us all"，他在很短的时间内写完作文让我们都很惊讶, 此复合句主要描述的是某事让我们惊讶，某事就是该复合句的主语，因此"That he finished writing the composition in such a short time" 便是该复合句的主语从句。
主语从句使用陈述语序，其通常结构为“引导词+ 主语+ 谓语+ 其他成分”；但当连接代词同时充当从句主语时，其结构为“连接代词+ 谓语+ 其他成分”。
时态：主语从句的时态不受主句时态的影响和限制
引导主语从句的连词主要有:
从属连词:that、whether （只起连接作用，不充当句子成分）
连接代词:who、whoever、whom、whose、what 、whatever 、which 、whichever （既有连接作用，又做从句的主语、宾语、表语或定语）
连接副词:when、where 、how 、why whenever、wherever（既有连接作用，又做从句的状语）
例句：
1. that引导
例句：That you are coming to London is the best news I have heard this long time. 你将来伦敦是好久以来我听到的最好消息。
2. whether引导
例句：Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
3. 连接代词引导
例句：Whoever is top from wins the game when two matched players meet. 两强相争勇者胜。
4. 连接副词引导
例句：How this happended is not clear to anyone. 这件事怎样发生的，谁也不清楚。
5. what引导
例句：What struck me was that they have all suffered a lot. 给我很深印象的是他们都受过很多苦。
一、形式主语it
有时为了考虑句子平衡，避免句子头重脚轻,通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。
常用句型如下：
(1)It + be + 形容词+ that 从句
(2) It + be + 名词+ that 从句
(3) It + be + 动词的过去分词+ that 从句
例1：That they refuse to sign the petition required great courage. （他们拒绝在请愿书上签字这是需要很大勇气的。）
It做形式主语：It required great courage that they refuse to sign the petition.
例2：What he meant is clear enough . 他是什么意思很清楚。
It做形式主语：It is clear enough what he meant.
如果句子是疑问句，则必须用带形式主语it的结构：
例句：Is it true that he is the girl’s father? 他是那女孩的父亲，是真的吗?
二、连词that的省略问题
引导主语从句的连词that 有时可省，有时不能省，其原则是：若that引导的主语从句直接位于句首，则that不能省略；若that引导的主语从句位于句末，而在句首使用了形式主语it，则that可以省略：
例句：That you didn’t go to the talk was a pity. 很遗憾你没去听报告。(that不可省) 例句：It was a pity (that) you didn’t go to the talk. 很遗憾你没去听报告。(that可省) 三、主句的谓语动词使用问题
一般情况下，主语从句做主语相当于第三人称单数做主语，主句的谓语动词用单数；如果由and 连接两个或两个以上的主语从句做主语，则主句的谓语动词用复数。（区别：看到底
有几个主语从句做主语）
初中英语语法宾语从句讲解_专项练习及答案
初中英语语法宾语从句讲解，专项练习及答案注意！宾语从句小口诀： 宾语从句三注意，时态语序引导词； 主句一般现在时，从句不需受限制； 主句一般过去时，从句须用相应时； 陈述句转化that引，一般疑问句用if/whether, 特殊问句疑问词，引导词后陈述式。 一、基本讲解 1 概念:在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。eg, He said he was good at drawing. (动词宾语) He asks him how long Mike has been down . (动词宾语) Miss Zhang is angry at what you said. (介词宾语) 2.连接词 (1) .陈述句转化成宾语从句时，引导词用that,口语中常常省略。 e.g, She told me (that) she would like to go with us. (2)以whether 或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序 eg, I wonder if /whether u have told the new to Li Lei . 注意：一般情况下，whether 和if 可以互用，但有些情况例外。 a. 当从句做介词的宾于是只用whether 不用if eg, We are talking about whether we'll go on the pinic. b. 引导词与动词不定式或not 连用时，只用whether. eg, Please let me know what to do next. Could you tell me whether u go or not? c. if当如果讲时，引导的是条件状语从句，这时不能用whether. (3).特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序。 E.g. Could you tell me what's the matter\wrong with you? 特殊情况：：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词＋do you think＋陈述句语序。 3.宾语从句时态
高中英语语法：主语从句的考点分析与专项训练
高中英语语法主语从句 第一节主语从句 1．考点解析。 1．主语从句一般分为三类：由what等代词引导的主语从句；由连词that 引导主语从句，多数情况下由it作形式主语，that从句放到句子后面去；由连接代词或连接副词（或whether）引导的主语从句。 What they are after is beauty. It is not your fault that we can’t arrive on time. When they will arrive has not been decided. 2. 由关系代词what引导的主语从句，也可由whatever（“所…的一切”）或 whoever（“一切…的人”）引导。 Whatever he wants is your support. Whoever comes will be welcome. 3. 大多数主语从句都可用it代替，作形式主语，把主语从句放在句尾。要注意it代替主语从句和it引导的强调句的区别。强调句的结构是it is/was….+that…，强调人是可把that 换做who，whom，whose。如强调的是状语时，也只能用that,而不能用when, where, how, why等。 It was in Paris that they fell in love with each other.

初中英语语法——三大从句汇总(重点笔记)知识讲解
初中英语语法——三大从句汇总 在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即 状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （一）关系代词who, whom和 whose的用法 who代替人，是主格，在定语从句中作主语。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。
I will never forget the teacher who taught us chemistry in the first year of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。例如：Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先生你认识吗？ This is the student whom my father taught ten years ago.这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。例如：The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。 Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字，你知道吗？（关系代词whose指代先行词hotel，正式用法应该用of which。whose window=the window of which，意思是：the window of the hotel。） （二）关系代词which的用法 which代替物，在定语从句作主语或宾语，作宾语时还可省略。例如： I do not like stories which have unhappy endings. 我不喜欢有不幸结局的小说。（which可以换成that） Tom works for a factory which makes watches. 汤姆在一个制表厂工作。（which可以换成that） （三）关系代词that的用法 that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。例如： Is she the girl that sells newspapers? 她是卖报纸的那个女孩吗？（that可以换成who） Where is the ice-cream that was in the fridge?
xx考研英语语法复习主语从句
xx考研英语语法复习主语从句 在复合句中充当主语成分的句子叫作主语从句。具体形式为：引导词引导一个从句作主语;或者it作形式主语+谓语/系表结构+引导词+从句。 ⑴陈述句充当主语从句，连词为that(that没有实际含义，在从句中只起连接作用，不在从句中作任何语法成分)，从句为"that+陈述句"，that不能省略。 【例句】 That Chris Lee won the champion of Super Girl in xx arouse wide public concern. 李宇春赢得xx年超女冠军这件事引起了社会的广泛关注。 ⑵一般疑问句充当主语从句，连词为whether(whether"是否"的含义，在从句中只起连接作用，不在从句中作任何语法成分)，从句为"whether+陈述句语序"，whether不能省略。 【例句】 Whether this is true or not remains a mystery. 这是对是错还是个谜。 ⑶特殊疑问句充当主语从句，连词为特殊疑问词(特殊疑问词都有自己的含义，在从句中作一定的语法成分)，从句为"特殊疑问词+陈述句语序"，特殊疑问词不能省略。 【例句】 例1 --what
What caused the aident remains unknown. 是什么引起了这一事故仍然。 例2--where Where my wife and I should enjoy our honeymoon is still unsettled. 我太太和我应该去哪享受我们的蜜月还没有最后决定。 例3 --which Which university I should choose to continue my further education is a question of great importance. 我应该考哪个大学的研究生是个很重要的问题。 例4--when When and where the test will be given is not yet decided. 什么时候在什么地方进行考试还没定下来。 例5---ever Whoever gets the job will have a lot of work to do. 任何得到这份工作的人都将要有很多工作要做。 例6--how How we can protect the grain from damp needs to be discussed. 我们怎样才能保护粮食不受潮需要讨论讨论。 3.It句型
(完整版)初中英语语法专题(状语从句)讲解
初中英语语法专题（状语从句）讲解 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句：
Finish this so that you can start another.把这个做完，你可以开始另一个。 结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。 让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。 方式状语从句： Students do as the teachers say.学生们按照老师说的去做。 比较状语从句： The work isn't as easy as I thought.这项工作比我想象得难。 例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别： when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用 （=while）。如： When he came in, his mother was cooking. When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.
主语从句详解及练习-附答案
语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：that, whether, if （不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 1. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if 和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副 词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名 作家的。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句 （3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如：He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去 上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
初中英语定语从句的用法解析
初中英语定语从句的用法解析 【摘要】定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。 【关键词】定语从句先行词关系代词关系副词 一、英语中的定语从句与汉语中的定语位置不同。 在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如： The man who / that I saw at the school gate yesterday is my English teacher. 先行词定语从句 昨天我在校门口看见的那个人是我的英语老师。 二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如： I am waiting for the boy who /that is wearing a red coat. （主语） 先行词关系代词 我正在等穿着红色外套的那个男孩。 The dictionary that / which my sister gave me last Sunday is very expensive.(宾语) 先行词关系代词 我姐姐上周星期天给我的那本字典很贵。 The woman is his mother whose name is Linda Brown. (定语) 先行词关系代词 那个是他的母亲，名叫琳达·布朗。 That is the house where my father used to live.(状语) 先行词关系副词 那是我父亲曾经居住过的房子。 三、初中英语中的定语从句关系代词或关系副词的具体用法。 1. who指人（也可用that），在定语从句中作主语，也可作宾语。如： Yesterday I helped an old man who / that lost his way. （主语） 昨天我帮助了一位迷路的老人。 Mr Wang is the man (who / that / whom )you met in the zoo this morning.(宾语) 王先生就是今天早上你在动物里遇到的那个人。 注意：关系代词who指人,作宾语时，可用whom代替；作宾语时，关系代词可省略。作其它成分，关系代词则不能省略。 2. whose指人，也可指物。在定语从句中作定语。 The boy whose mother is ill is staying at home to look after her today. 其母亲生病的那个男孩今天呆在家里照顾她。 I have a story book whose cover is red. 我有一本封面是红色的故事书。 3. which指物（也可用that），在定语从句中作主语，也可作宾语。如： Football is a game which / that is liked by most boys. （主语） 足球是被大多数男孩喜欢的运动。 I don’t believe the news which / that Tom won the game. (宾语)
高考英语主语从句讲解
高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather. When we’ll start tomorrow will be told soon. Where the test will be given is not yet decided. 4. 主语从句后置：为了避免主语冗长,句子头重脚轻,经常用it 作形式主语,主语从句放在后面作真正的主语. 例: That we shall be late is certain. -- It’s certain that we shall be late. 1）用it 作形式主语的结构 A. It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B. It + be + 名词词组+ that 从句(an honour, a fact, a pity, etc）如： It is a pity/shame that... 遗憾的是…… It is a surprise that…令人惊奇的是… It is a fact that… …是事实It is common knowledge that… …是常识 It’s a pity that we can’t go. C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day. It doesn’t matter whether she will come or not. 2) 对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从
(完整版)主语从句详解
主语从句详解 一、概述 在句子中起名词作用的各种从句统称为名词性从句.根据它们在句中的语法作用, 这类从句又可分为主语从句、同位语从句、表语从句和宾语从句. 二、主语从句主要有四类 （1）由连词that引导的主语从句:引导词that无含义/在句中不做成分/不可以省. 例如：That you will win the medal seems unlikely. That you are so indifferent bothers me. That she survived the accident is a miracle. （2）用连词whether 引导的主语从句: whether有含义(是否)/在句中不做成分/不可以省. 注意：引导主语从句, 不能用if, 只能用whether. 例如：Whether we will hold a party in the open air tomorrow depends on the weather. Whether she is coming or not doesn’t matt er too much. （3）用连接代词引导的主语从句 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中, 其连接代词在句中起名词性作用, 担当一定成分. 例如：What you need is more practice. What I want to know is this. Whatever we do is to serve the people. 注：whatever / whoever的功用 whatever, whoever在主语从句中不含疑问意义.它引导主语从句, 并在从句中作主语、宾语、表语等. whatever = anything that; whoever = anyone who.要注意和whatever, whoever引导的让步状语从句的区别. Whoever breaks the law should be punished. （主语从句） （＝Anyone who breaks the law should be punished. ） Whoever breaks the law, he should be punished. （让步状语从句） （＝No matter who breaks the law, he should be punished. ） （4）用连接副词when, where, why, how引导名词性从句(其连接副词有含义,在句中作状语.) 例如:Where we should leave it is a problem. When they will come hasn’t been made pubic. 三、注意点: it构成的主语从句 （1）由连词that引导的主语从句, 在多数情况下放到句子的后面, 而用代词it作形式主语. 例如：That light travels in straight lines is known to all. =It is known to all that light travels in straight lines.

初中英语从句语法讲解
从句 从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。(参见以下各条） ３、各从句在句子中的位置以及用法: (1) 表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后。 例如：Thaｔ is wｈｙ he did not ｃomｅto scｈooｌ yeｓtｅrday. / It is ｂｅcause y ｏu ａｒｅ so ｃleveｒ. (2) 宾语从句:在句子中作及物动词或介词的宾语。 ①基本形式：(主句＋）连词＋从句主语+从句谓语+... ②关于宾语从句连词的选择: 若从句来源于一个陈述句,那么,连词用thaｔ，在口语中thａｔ可以省略； 若从句来源于一个一般疑问句，连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如whａt,who，wｈere,when等）例如：Theｙｂeｌieve that the comｐｕter wiｌl fｉnally ｔake the plaｃe of hｕ man beｉnｇs．(他们相信计算机终将代替人类。) （从句本来就是陈述句)/ I wonder wh ｅther I shoulｄｓay sｏmｅthing ｆor hiｍｔo ｔhe ｈeａｄｍaster． (我不知道是 不是该为他在校长跟前说点什么。) (从句来源于一般问句ＳhalｌＩ say sｏmｅthｉng ｆor him to the headｍaster?)/ Ｈe askeｄ me wheｒe he cｏuｌｄｇeｔ such ｍedicin ｅ. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where caｎｈe get such me ｄｉｃｉne?) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时; 如主句是过去时，从句则相应地使用过去某一时态，遇到客观真理时仍然用现在时。如:Ｉ t ｈink Ｉ will dｏ better ｉn Eｎglish this ｔerm．（我想本学期我的英语会学得好点。) / Thｅ tｅａcher askｅd the boｙ if ｔhe eａrth ｉｓroｕnd. (老师问那个男孩地球 是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待： bｅｓoｒrｙ / afraid / sｕrｅ／ｇlａd +that从句,如:I’m sｏrｒy I’m late. (对 不起,我迟到了。)/ Ｉ’m afｒａiｄ hｅ iｓn’t iｎat the ｍｏｍent.(恐 怕他此刻不在家。) (3) 状语从句:在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原
