状语从句的结构和特点
状语从句通常由从属连词引导,从句中的谓语用非谓语形 式(不定式、分词、动名词等)。不同类型的状语从句有 不同的结构和特点,如时间状语从句常用when, while, as 等引导,条件状语从句常用if, unless等引导。
状语从句与并列句、复合句的关系
状语从句与并列句和复合句有密切关系。并列句由并列连 词连接两个或两个以上的简单句,而复合句则包含一个主 句和一个或多个从句。状语从句可以作为复合句中相反的假设条件,主句说明在这个假设条件下会出现的结果。常用if引导, 从句和主句的谓语动词都要用虚拟语气。
典型例句分析
Unless you change your mind, I won't be able to help you.( 除非你改变主意,否则我帮不了 你。)

because引导原因状语从句

because引导原因状语从句

because引导原因状语从句1. 结构:原因状语从句通常由从属连词"because"引导,后面跟着一个完整的句子。

2.位置:原因状语从句可以置于主句之前或之后,具体位置取决于句子的语气和语境。

-如果原因状语从句在句首,通常需要用逗号与主句隔开。

例如:"Because it was raining, we stayed indoors."-如果原因状语从句在句尾,一般不需要逗号。

例如:"We stayed indoors because it was raining."3. 引导词替代:除了"because",其他常见的引导词有"since"、"as"、"due to"、"owing to"等。

它们在引导原因状语从句时具有相同的作用。

例如:"Since I had an early meeting, I couldn't stay out late."4. 强调结构:有时候,为了强调原因状语从句,可以使用"because of"加名词或代词的形式。

例如:"He couldn't attend the meeting because of his illness."5. 注意点:-原因状语从句解释主句的原因,因此主句是结果或效果,而从句是原因或解释。

-原因状语从句不能独立成句,它必须与主句一起构成完整的意思。

-原因状语从句可以回答"why"的问题,解释为什么某个行为或情况发生。

下面是一些例句,展示了"because"引导原因状语从句的用法:1、She didn't go to the party because she had to study for her exam.她没去参加聚会,因为她得准备考试。

原因状语从句

原因状语从句
? It rained last night, for the ground is wet this morning.
注意:
? 表示...的原因是因为 ...的时候,用the reason why...is that... 而不是 the reason why...is because... 如: ? The reason why I call you is that I miss you.
Adverbial Clause of Reason 原因状语从句
引导原因状语的从属连词:
? because ? as ? since ? seeing (that) ? now (that) ? considering (that) ? in that ? ......
Because
? because,因为,表示直接的原因,语气最强。
When
? when 也可以引导原因状语从句,表示既然。 如:
? I won't tell you when you don't want to listen.
For
? for,因为,是并列连词,它有时可表示因果关系 (只能放在主句之后)是对前面的分句进行解释, 只能表示附加或推断的理由。 如:
? Since that this method doesn't work, let's try another.
? since可用于省略句,其余则不能。 如: ? Since so, there is no more to be said.
Now that, Seeing that, Considering that, In that
? why提问的句子,必须用 because回答。 如: ? -Why didn't he come yesterday? ? -Because he was ill.

1)①because“因为”,表示直接的原 因,语气最强。 ②why提问的句子,必须用because回 答。
eg:I stayed at home because it rained.
2) since引导的原因状语从句一般放于 主句之前表示已知的、显然的理由(通 常被翻译成“既然”= now that), 较为正式,语气比because弱。
A.What;so
B.How;such
C.What a;such an D.How a;so an

解析:根据翻译 你学习这么刻苦肯定通 过考试。hard是形容词所以选C
6.This meeting is __important that you mustn’t miss it.
A.Very B.such C.so D.too
解析;翻译是 如此重要,句中 important属于形容词所以选C
7.She was __angry __couldn’t say a word .
students could understand it.
A.so;that
B.such;that
C.too;to
D.very;that
解析 :根据题意从A和B中选,因为 easy English是表示简单英语,属于 名such修饰名词,所以本题选B

状语从句
初中英语专项复习
状语从句是指句子的状语由一个从句充当, 用来 修饰主句中的动词、形容词或副词等。状语从句由从 属连词引导, 与主句连接, 放在句末时, 一般不在 前面加逗号。状语从句根据它表达的意思可分为时间 、原因、条件、比较、结果、目的等类型。

引导词
例句
He spoke so fast that
5. when, while, as意为“当……的时候”。 (1)when表示在某一特定的时间点(段),主句的动作和
从句的动作同时发生或先后发生。when引导的时间 状语从句的谓语动词既可以是非延续性动词,也可 以是延续性动词。如: When we lived in town, we often went to the theatre. 我们住在城镇里的时候常去剧院看戏。
last night. 昨晚直到12点我回来他才停止工作。
7. as soon as… 意为“一……就……”, 强调主句的动 作紧接着从句的动作。如:
As soon as I arrive in Beijing, I will call you. 我一到达北京就会打电话给你。 8. so… that, such… that意为“如此……以至于……”, 引导结果状语从句。基本规则是:so后面接形容词 或副词, such后接名词。但有几点要特别注意: (1)such是形容词, 它所修饰的名词可以是可数名词, 也可以是不可数名词;名词前面可以带形容词, 也 可以不带。如果其后是单数可数名词, 前面需加不 定冠词a或an。因此, such… that… 的句型结构可 分为以下三种:

2. He couldn't walk because his leg was broken.
关于not…because结构
该结构中的否定词有时否定主句,有时否定从 句,一般要根据句子的意思作出正确或合乎逻 辑的理解。若not否定主句,最好在because 之前用逗号,否则会引起歧义,如下句在没有 特定上下文时就有两种解释: I didn’t go because I was afraid. 我没有去是因为怕。/ 我不是因为怕才去。
例如:
I do it because I like it. 我做这件事是因为我喜欢。
because习惯上不与so连用
汉语习惯上说“因为…所以…”,但英语习惯 上却不能将 so与because 连用: 如:因为下雨,所以我们呆在家里。 正:Because it was raining, we stayed at home. / It was raining, so we stayed at home.
误:Because it was raining, so we stayed
at home.
because从句与 because of短语的转换
Because引导的原因状语从句有时可与 because of 短语转换,because of后加的原 因可以为好或坏
但最正规的还是because He can’t come because he is ill. He can’t come because of his illness. 他因病不能来。
达标测评
I. 在下列句子的空格中填入适当的连词(每空一词):
1. —Why didn't you come? — ________ my father wouldn't let me.
2. He was listening to the radio ________ he didn't hear the knock at the door.

短语的转换 四、关于not…because结构
because引导原因状语从句
because引导的从句一般放于主句之后, because从句位于句首时要用逗号分开,放在 句末 时,可不用逗号分开。because表示直 接原因, 语气最强, 最适合回答 why引导的 疑问句。
3. I came back
the rain.
4. We didn't get home till after midng the bus.

II. 句型转换 (用so或because of )
1.He lay in bed because he had caught a bad cold.
