原因状语从句练习题及解析答案详解
原因状语从句练习题及解析答案详解原因状语从句是表达某件事情发生原因的从句，由because，since，as等引导；目前在英语中是比较常用的一类从句。
下面将为大家列举一些原因状语从句练题并附上详细解析答案，希望对大家在研究中有所帮助。
练题2. We must obey the traffic rules _____________ we may cause accidents.3. I didn't go swimming this afternoon ____________ I was busy.4. This is _________________ the little girl burst into tears.5. The reason why he is late is ______________ his car broke down.答案详解1. As指"由于"，表示原因，因此所填的状语从句为原因状语从句，因而可以形成“因果关系”，完整的句子为：“由于他病了，他没有来参加晚会。
”2. 一个句子中只有一个主语和一个谓语，在前面的句子中已经有了谓语，所以只能用连词“or”“and”“but”等来连接两个句子。
因此题目应填因果关系连词because。
完整的句子为：“我们必须遵守交通规则，因为否则我们可能会造成事故。
”3. as是一个比较平常的原因状语从句的引导词，as引导的原因状语从句，常作句子的前置状语。
表示由于，因为；它所在的句子通常已经表示了结果。
完整的句子为：“我今天下午没去游泳，因为我很忙。
”4. 笑是因为快乐，而哭是因为悲伤。
本句话含有转折关系，故可选but，表示转折；句意为“这就是为什么小女孩会哭"。
5. 这个句子又可以按照"why"型原因状语从句来处理，即后面宾语从句的结构就是“ “the reason” + “why” + “主语” + “谓语””，因此which是不可用的，答案应为：the reason why，意为“他迟到的原因是因为他的车坏了。
高中英语状语从句讲解及练习(含答案)
状语从句状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。
一、时间状语从句引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time等。
时间状语从句中一般用一般现在时或一般过去时。
1．When , while, as都可解释为“当```的时候”但侧重点有所不同。
1)WhenEg: When I arrived home , I had a little rest.注意点：when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。
Eg: When (she was) walking along the street, she met her class teacher.2)AsAs 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”Eg: He sang as he danced.(一面```一面)You will grow wiser as you grow older.(随着)3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。
Eg: While we were working, they were having a rest.While (they were) having a discussion, they got very confused.注意点：while 有对比的含义，解释为“然而”。
eg: I prefer black tee, while he likes coffee.2．until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。

2.原因状语从句原因状语从句表示主句中动作或状态发生的原因或理由, 可位于主句之前,之后或插在主句中间。
主句表示结果, 从句表示原因, 主要由because, as, since, for,seeing ( that), considering ( that), now (that), in that, not ... because 等引导。
1) because“因为’’, as‘‘由于”, since “既然”, for“因为”because意为“因为”, 表示直接的原因或理由, 着重点在从句, 用于回答why,语气最强。
He is absent today because he is ill.当主句为否定句时, 从句because须用逗号与主句隔开, 否则容易引起歧义。
I didn’t visit him, because I wanted to borrow some books.我没去拜访他, 因为我想借几本书。
I didn’t visit him because I wanted to borrow some books.我不是因为想借几本书才去拜访他的。
as意为“由于”, 表示十分明显的原因, 所引导的从句常位于主句之前, 有时也可位于主句之后, 一般说明因果关系, 着重点在主句, 原因或理由只是附带说明, 不用于回答why的问题, 常用于口语。
As it is snowing, we shall not go to the park.As this book is written in simple English, it is suitable for beginners.since意为“既然, 由于”时表示对方已知的、无须加以说明的既成事实的理由, 只是一个附带说明。
since = as it is the fact that ...全句中心在主句。
如从句表示的原因不是确定的事实, 就不能用since,通常用because.Since everybody is here, let’s begin our discussion.Since you seem to know them, why don’t you introduce me to them?for是一个并列连词, 由for连结的表原因的句子常看作并列句, 它只提供一些补充说明或对前一个分句加以解释, 不可前置。
与because 不同的是:because引导的从句位置可前可后, 而for引导的分句只能后置, 且往往须用逗号或分号与前一个分句分开。
I didn’t go to see him, for a heavy snow was falling.The days were short, for it was now December.有时, for引起的从句并不表示原因, 而是表示一种推断或解释, 而because则不能。
Someone in the house must be ill, for a doctor has just come out.He couldn’t have seen me, for I was not there.一、填入恰当的连词1. I didn’t go to school yesterday _________ I was ill.2. ________ everybody is here, let’s begin our meeting.3. ________ you are in poor health, you should not stay up late.4. I asked her to stay to tea, ________ I had something to tell her.5. ________ all the passengers are here, why don’t we start at once?6. Bill won’t make any progress ________ he doesn’t study harder than before.7. He might have gone to bed, ________ the light went out.1.because2.Since3.As4.because5.Since6.because7.for二、填入恰当的连词1. ______ you do not understand, I will explain again.2. ______ Jane was the oldest in this family, she had to look after the others.3. He must be ill, ______ he is absent today.4. The teacher must be strict with you ______they want you to make great progress.5. _____your father is well again, you no longer have anything to worry about.6. The day breaks, _____the birds are singing.7. ______ you are ill, you’d better go to see the doctor.8. ______ she was late for class, she had to say sorry.1.since2. As3. for4. because5. Since6. for7. Since8. As2) 用下列短语引导:seeing (that) “鉴于, 既然”, considering (that) “考虑到”now (that)“既然”, in that “因为”, not ... because “不是因为”not that……but that “不是因为……而是因为, ’seeing that与considering that同义, 含义近似since,所引导的句子中心在主句, 重在强调结果。
Seeing that the weather is bad, we’ll stay at home.Considering that they are newcomers, they’ve accomplished a lot.now that的含义与since(“既然”）接近, 区别在于:since表示原先已存在的情况, 而now that 表示由于新情况的出现而促成某事发生。
Now that it has stopped raining, let’s start at once.Now that you are all here, let’s try to reach a decision.in that作“因为”解时, 由于介词in的含义是指“在……方面”, 有限制作用, 因此多指由于某一方面的原因或理由, 不能位于句首。
I like the city, but I like the country better in that I have more friends in the country.I could understand his point of view, in that I’d been in a similar position myself.not ... because意为“不是因为”, 该结构中的not否定because。
She didn’t marry you because you had money.她不是因为你有钱才嫁给你。
The machine didn’t stop because the fuel was used up.机器不是因为燃料耗尽才停下来的。
not that ... but that作“不是因为……而是因为”解。
Not that I don’t like the film, but that I have no time for it.He felt a bit worried, not that they were not working hard, but that they didn’t pay enough attention to safety.家庭作业选择恰当的答案1.
