状语从句知识点详解(初中英语专项复习)状语从句的概念: 用一个句子作状语来修饰动词和形容词,以表明动作发生或状态存在的时间、地点、原因等,这个句子就叫做状语从句。

(cook是延续性的动词,cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋,而我姐姐喜欢看小说。
(while表示对比)when和while的区别还有:while引导的时间状语从句多用于进行时态,而when引导的时间状语从句多用于一般时态。

二、连接词that: I think that you can pass the exam.Whether/if: I don’t know what the word means.“Wh”: I don’t know what the word means.I don’t know where he found the book.只用whether的情况:1. 与or not连用:I don’t know whether it’s raining or not.2. 与动词不定式连用:He doesn’t know whether to accept the invit ation.3. 连接词前有介词时:It depends on whether he is coming.三、时态1. 主句是一般现在时态,从句根据实际情况而定(各种时态均可)She wants to know what he has done for the exam.2.主句是一般过去时态,从句用相应的过去的时态。

状语从句(2):原因、目的和结果状语从句在上一模块中,我们学习了表示时间的状语从句,那么如果要表达一个行为的原因、目的或结果时,又该使用什么样的结构呢?首先我们来看一下本模块中出现的几个句子:(1) She's my hero because she's one of the best table tennis players inthe world. 她是我心目中的英雄,因为她是世界上最优秀的乒乓球运动员之一。
(2) ... and wrote books so that they could learn about how he treatedthe sick.……并且著书让他们(当地的医生和护士)了解他是如何医治病人的。
(3) At that time, there were few doctors, so he had to work very hardon his own. 那时医生很少,所以他不得不很辛苦地独自工作。
语从句表示目的,句(3) 中so 引导的状语从句表示结果。
那么,原因、目的和结果状语从句各有什么特点,该如何使用呢?1. 原因状语从句如果从句表示的是主句行为的原因,就构成原因状语从句。
原因状语从句由表示原因的连词引导,常用的是because。
例如:He failed the exam because he was too careless. 他太粗心了,所以没有通过考试。
Many people were dying because they did not get to hospital quickly enough.很多人因为不能即时入院治疗而生命垂危。
since 也可以用来引导原因状语从句,表示显然的或已为人所知的理由,常译为“因为;既然”。
例如:Since everyone is here, let's start. 既然大家都到齐了,我们就开始吧。
中考重点状语从句中原因和结果的表达方式状语从句是英语中常见的从句类型之一,用来表示一个句子中某个成分的状况或情况。
其中,原因状语从句和结果状语从句是中考重点,下面将分别介绍这两种类型状语从句的表达方式。
一、原因状语从句的表达方式1. 使用连词"because"或"as"引导:原因状语从句通常由连词"because"或"as"引导,"because"直接表达原因,"as"则表示由于某个原因。
例如:I couldn't go to the party because I was sick.(由于生病,我无法去参加聚会。
)As it was raining heavily, we decided to stay at home.(由于下雨很大,我们决定待在家里。
)2. 使用其他连词引导:除了"because"和"as",我们还可以使用其他连词如"since"、"due to"等来引导原因状语从句。
这些连词在用法上有细微的差别。
例如:Since he was tired, he didn't want to go out.(由于他累了,他不想出去。
)Due to the bad weather, the match was canceled.(由于天气不好,比赛被取消了。
)3. 句型倒装:在原因状语从句中,为了强调或使句子结构更复杂而运用了部分倒装的情况也是很常见的。
例如:Not until he finished his homework did he go to bed.(直到他完成作业,他才去睡觉。
)Only when she saw the exam paper did she realize she had made many mistakes.(直到她看到试卷,她才意识到自己犯了许多错误。
“原因状语从句”、“结果状语从句”和“目的状语从句”的用法北师大版高中英语必修2 Unit 5 lesson 3:Adberbial Clauses (cause & result & purpose )一、Adberbial Clauses of Cause原因状语从句连词有:because, since, as; now that, in that, seeing that, considering that; when等。
(一) because, since, as1.表示不知道的原因时用because, 通常它被置于主句之后。
You want to know why I’m leaving? I’m leaving because I’m full.2. for是并列连词。
如果不是因果关系,而是对前面主句的内容加以解释或推断时,只能用for。
It’s morning now, for the birds are singing.3. 表示已经知道的原因时用as或since, since要比as正式一些,它们通常被置于语句之前,但有时却相反。
Since /As the weather is so bad, we have to delay our journey.4. 下列情况下只能使用because:①在回答why的问句时;---Why did you not come yesterday?---Because I was ill.②在用于强调句型时;It was because I was ill that I didn’t come yesterday.③被not所否定时。
(“not ... because”结构中的not否定的是because引导的整个从句)The country is not strong because it is large. 国强不在大。
(二) now that, in that, seeing that, considering that(这几个词汇与since引导的原因状语从句意思相近, 都表示“既然”。
