原因状语从句
1. 定义：在句中用来说明主句原因的句子叫原因状语从句。
2. 常用引导词: because(因为)，since(既然)，as(由于)，for(因为)
3. 时态：原因状语从句一般都是根据实际情况选用适当的时态，通常是主过从过、主现从现。
4. because, since, as和for的区别：
(1)because引导的原因状语从句一般放在主句的后面。because从句位于句首时要用逗号与主句分开，放在句中时可不用逗号分开。because表示直接原因，语气最强，适用于回答why引导的疑问句。
注意：because和so不可同时出现在一个句子里。
I didn’t go because I was afraid. = I was afraid so I didn’t go. 我没去,因为我害怕。
—Why not go out to see the movie with us 为什么不和我们一起去看电影呢？
—Because I have to finish my report. 因为我得完成我的报告。
(2)since引导的原因状语从句一般放在主句之前，表示已知的、显然的理由(通常被翻译成 “既然”，相当于now that)，较为正式，语气比because弱。
Since the weather is so bad, we have to stay at home.
由于天气如此糟糕,我们不得不待在家里。
Since everyone is here, let’s begin our meeting.
既然每个人都在这儿,我们开始开会吧。
Now that you have grown up, you should not rely on your parents.
既然你长大了，就不该依靠你的父母了。
(3)as 引导原因状语从句时表示附带说明的双方已知的原因，含有对比说明的意味，语气比since弱，较为正式，位置较为灵活(常放在主句之前)。
As the weather is so bad, we have to stay at home.
由于天气如此糟糕,我们不得不待在家里。
I went to bed early, as I was exhausted. 我睡得早，因为我精疲力尽了。
(4)for引导的是并列句，表示原因，但并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明。for引导的并列句只能放在主句之后，并且必须用逗号将其与主句隔开。
He could not have seen me, for I was not there. 他不可能见过我，因为我不在那里。
He seldom goes out now, for he is very old. 他现在难得出门了，因为他年事已高。
5. because和because of 的区别：
(1)because是连词，其后接原因状语从句或回答以why开头的特殊疑问句。
(2)because of是复合介词，其后接名词、代词或动名词，或者由what引导的名词性从句。
They didn’t go to the museum because it rained. ( it rained是句子)
= They didn’t go to the museum because of the rain. (rain是名词)
因为下雨，他们没去博物馆。
【典例1】（2021深圳光明区八年级下期末）
Because ________ this, the home for penguins has almost completely disappeared.
【答案】of
【解析】句意：正因为如此，企鹅的家几乎完全消失了。根据语境，设空处表"因为、由于"，分析句式，设空后是代词this,因此应用because of短语，其后接名词（短语）或代词。故填of。
【典例2】（2021广州中考）
He worked on it with the greatest care, but the corn was dying ______there had been no rain for a long time.
A. because B. where C. when D. if
【答案】A
【解析】考查从属连词辨析。考查原因状语从句。句意：他悉心地照料着他的玉米,但他的玉米却因长时间没有下雨快死了。because“因为”,引导原因状语从句;where“哪里”,引导地点状语从句;when“当……时”,引导时间状语从句;if“如果”,引导条件状语从句。根据设空前后的内容为因果关系可知,此处应用because,故选A。
【考点突破】
1. Once I flew home to visit Grandma and found that all the staff in the nursing home knew the details of my life_______ they often read letters to her. (2021广州白云区二模)
A. if B. when C. as D. but
【答案】C
【解析】本题考查连词。A. if如果；B. when何时；C. as因为；D. but但是；根据句意，有一次我乘飞机回家看望奶奶，发现养老院的所有员工都知道我生活的细节，因为他们经常给她读信。分析上下文可知，是因果关系，选项中只有as可意为因为。故选：C。
2. The letters of Abigail Adams to her husband, John Adams, are part of Revolutionary War history _______ they serve as a firsthand eye-witness account of political life during this time.
(2020广州白云区一模)
A. and B. because C. so D. or
【答案】B
【解析】本题考查连词。and 和；because因为；so因此；or或者。空格前后两句是因果关系，即阿比盖尔 亚当斯写给她丈夫约翰 亚当斯的信是革命战争（独立战争）历史的一部分，因为他们是当时的政治生活的第一手见证记录。故选B.
3. He became nervous, upset, and had trouble in sleeping at night _______ the accident.
(2021广州越秀区一模)
A. because of B. because C. as D. since
【答案】A
【解析】because of是复合介词，其后接名词; because是连词，其后接原因状语从句。而题目中the accident正是名词词组，因此本题选A。
4. ________ smoking has harmful effects, ________ many people give up smoking.
A. Because; so B. Because; / C. Because; for D. If; so
【答案】B
【解析】because和so不可同时出现在一个句子里。故选B
5. --- Why did you get up early yesterday morning
--- ________ I wanted to do my homework.
A. Since B. As C. so D. Because
【答案】D
【解析】because表示直接原因，语气最强，适用于回答why引导的疑问句。
过去进行时
1. 过去进行时的构成：
肯定句形式：主语+was/were+动词的现在分词.
否定句形式：主语+was not(wasn’t)/were not(weren’t)+动词的现在分词.
一般疑问句形式：Was/Were+主语+动词的现在分词
肯定回答：Yes, 主语+was/were.
否定回答：No, 主语+was not (wasn’t)/ were not (weren’t).
2. 过去进行时的基本用法：
(1)过去进行时表示过去某一段时间或某一时刻正在进行的动作。常用的时间状语有：at that time/ moment, (at)this time yesterday(last night/ Sunday/week …), at+几点钟+yesterday(last night / Sunday …)，when sb. did sth. 等。
They were having a class this time yesterday. 昨天这个时候他们正在上课。
(2)when和while表示“当……的时候”时，when后面通常接短暂性动词的一般时态，while后面通常接持续性动词的进行时态。
I was talking when the teacher came in. 老师进来的时候我正在讲话。
While you were writing, I was reading. 你在写东西的时候，我在看书。
He broke his leg when he was playing football.= He broke his leg while he was playing football. 他在踢球的时候把腿摔断了。
【典例1】（2021深圳中考）
The famous translator Xu Yuanchong _________ (sit) behind the window and staring at the computer screen.
【答案】was sitting
【解析】考查动词的时态。根据句意，著名的翻译许渊冲坐在窗户后面，盯着电脑屏幕。由空后的并列谓语结构and staring,可知这里应填入过去进行时（结构：主语+was/were + doing+其它），讲述的是过去发生的事情，主语为Xu Yuanchong, 所以填入was sitting。故答案为：was sitting。
【典例2】（2021深圳龙岗区八年级下期末）
That evening, Mr. Brown was ready to do the test while Mrs. Brown _______(cook) dinner in the kitchen.
【答案】was cooking
【解析】考查时态。根据句意可知此处是指当布朗夫人正在厨房里做饭的时候，布朗先生准备做这个测试，主句使用了一般过去时，从句中使用过去进行时，表示与主句动作同时进行，所以要用was cooking来填空。故填was cooking.
【考点突破】
1. --- I saw the light of your room was still on at two o'clock last night.
--- Oh, I _______ a football match of the Russia World Cup. (2020广东中考)
A. watched B. was watched C. am watching D. was watching
【答案】D
【解析】此题时态。提示词为two o'clock last night, 可知道对话中强调昨晚两点所发生的事情，即过去进行时的意义，故答案为D。
2. I'm sorry I didn't answer your call because I _____ online. (2021黑龙江齐齐哈尔改编)
A. was studying B. studied C. am studying D. study
【答案】A
【解析】考查时态。根据语境分析和从句中的didn't可知,(当时)没接到电话,是因为(那时)正在线上学习,应用过去进行时。故选A。
3. While Tom , I called him yesterday. (2020吉林改编)
A. read B. is reading C. was reading D. will read
【答案】C
【解析】根据yesterday可知用过去时,“我”打电话给汤姆时他正在读书, 并且while后要接可持续动作，故应用过去进行时。
4. I don’t know when he . When he here, I’ll call you in a minute. (2021四川成都高新区二模改编)
A. will come; will arrive B. will come; arrives
C. comes; arrives D. comes; will arrive
【答案】B
【解析】考查时态。第一空前的when引导宾语从句,根据语境可知,我不知道他将什么时候来(人还没到), 应用一般将来时。第二空前的When引导时间状语从句,主句和从句的时态一般遵循“主将从现”原则。由此可知,答案选B。
5. As I was trying to find my way out, I suddenly ____(hear) some noise. (2020内蒙古包头)
【答案】heard
【解析】句意:当我正努力找出路时,我突然听到一些吵闹声。本题考查时态。由时间状语从句中的 was trying可知本空也应该用过去的某种时态, hear为瞬间动词,故本空应该用一般过去时,故填heard。

原因状语从句
1. 定义：在句中用来说明主句原因的句子叫原因状语从句。
2. 常用引导词: because(因为)，since(既然)，as(由于)，for(因为)
3. 时态：原因状语从句一般都是根据实际情况选用适当的时态，通常是主过从过、主现从现。
4. because, since, as和for的区别：
(1)because引导的原因状语从句一般放在主句的后面。because从句位于句首时要用逗号与主句分开，放在句中时可不用逗号分开。because表示直接原因，语气最强，适用于回答why引导的疑问句。
注意：because和so不可同时出现在一个句子里。
I didn’t go because I was afraid. = I was afraid so I didn’t go. 我没去,因为我害怕。
—Why not go out to see the movie with us 为什么不和我们一起去看电影呢？
—Because I have to finish my report. 因为我得完成我的报告。
(2)since引导的原因状语从句一般放在主句之前，表示已知的、显然的理由(通常被翻译成 “既然”，相当于now that)，较为正式，语气比because弱。
Since the weather is so bad, we have to stay at home.
由于天气如此糟糕,我们不得不待在家里。
Since everyone is here, let’s begin our meeting.
既然每个人都在这儿,我们开始开会吧。
Now that you have grown up, you should not rely on your parents.
既然你长大了，就不该依靠你的父母了。
(3)as 引导原因状语从句时表示附带说明的双方已知的原因，含有对比说明的意味，语气比since弱，较为正式，位置较为灵活(常放在主句之前)。
As it is raining, you’d better take a taxi. 由于正在下雨，你最好乘坐出租车。
I went to bed early, as I was exhausted. 我睡得早，因为我精疲力尽了。
(4)for引导的是并列句，表示原因，但并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明。for引导的并列句只能放在主句之后，并且必须用逗号将其与主句隔开。
He could not have seen me, for I was not there. 他不可能见过我，因为我不在那里。
He seldom goes out now, for he is very old. 他现在难得出门了，因为他年事已高。
5. because和because of 的区别：
(1)because是连词，其后接原因状语从句或回答以why开头的特殊疑问句。
(2)because of是复合介词，其后接名词、代词或动名词，或者由what引导的名词性从句。
He didn’t come because he was ill.=He didn’t come because of his illness. 他因病没来。
【典例1】（2021深圳光明区八年级下期末）
Because ________ this, the home for penguins has almost completely disappeared.
【答案】of
【解析】句意：正因为如此，企鹅的家几乎完全消失了。根据语境，设空处表"因为、由于"，分析句式，设空后是代词this,因此应用because of短语，其后接名词（短语）或代词。故填of。
【典例2】（2021广州中考）

【答案】was sitting
【解析】考查动词的时态。根据句意，著名的翻译许渊冲坐在窗户后面，盯着电脑屏幕。由空后的并列谓语结构and staring,可知这里应填入过去进行时（结构：主语+was/were + doing+其它），讲述的是过去发生的事情，主语为Xu Yuanchong, 所以填入was sitting。故答案为：was sitting。
【典例2】（2021深圳龙岗区八年级下期末）

【答案】was cooking
【解析】考查时态。根据句意可知此处是指当布朗夫人正在厨房里做饭的时候，布朗先生准备做这个测试，主句使用了一般过去时，从句中使用过去进行时，表示与主句动作同时进行，所以要用was cooking来填空。故填was cooking.

A. will come; will arrive B. will come; arrives
C. comes; arrives D. comes; will arrive
【解析】考查时态。第一空前的when引导宾语从句,根据语境可知,我不知道他将什么时候来(人还没到), 应用一般将来时。第二空前的When引导时间状语从句,主句和从句的时态一般遵循“主将从现”原则。由此可知,答案选B。
B
5. As I was trying to find my way out, I suddenly ________
(hear) some noise. (2020内蒙古包头)
【解析】句意:当我正努力找出路时,我突然听到一些吵闹声。本题考查时态。由时间状语从句中的 was trying可知本空也应该用过去的某种时态, hear为瞬间动词,故本空应该用一般过去时,故填heard。
heard
