3.so/such ... that ... 结构中的 so, such 连 同它所修饰的成分共同位于句首表示强调时, 主句要用部分倒装。
So suddenly did he catch the disease that
the whole family were at a great loss. 他患病突然,全家人全然不知所措。 4.表示前面所说的情况也适合于后者时,
Not until the press reported the pollution did people know why the water supply had been cut off.
直到报纸报道污染情况,人们才知 道水供给为什么会被切断。
2.“only+状语”置于句首时,主句要进行 部分倒装。
Was it in the park that he met our new
teacher? 他是在公园里遇到我们的新老师的吗?
(3)强调句型的特殊疑问句结构:特殊疑问 词+is/was+it+that+句子其他部分?
注意:强调句型也可用于宾语从句中,但 注意语序要用陈述句语序。
高考英语语法一轮复习——状语从句讲解(附答案)

状语从句由从句担任的状语,在句子中可修饰谓语(或其它动词)、形容词、副词或是整个句子,它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。
第一讲时间, 地点状语从句时间状语从句:when, while, as, before, after, since , wheneveruntil, till, by the time(注意时态)as soon as, had hardly…when, had no sooner…than, (on doing sth…)the moment, every time/ each time, the first time, oncee.g: When he came, I had cleaned the classroom.He didn’t stop working until his mother came bake.He worked until his mother came back.As soon as he returned, he bought a new flat.He had no sooner returned than he bought a new flatHe came to scene the moment he heard the news.I thought her nice and honest the first time I met him.Once he makes up your mind, he won’t change his min d.It was two years before I met him again. = Two years passed before I met him again.注意点1. when引导的从句动词可以是延续性的或短暂性的,while引导的从句中动词必须是延续性的;while有时并不表示时间,而表示对比,表示“而”、“却”。

B.习惯表达式。 since 从句前后时态不一致。主句谓语用 is 或 has been, 从句用一般过去时;主句谓语用 was 或 had been,从句用过 去完成时。如: ①It is/has been three years since he joined the football club in our school. 他加入校足球俱乐部已三年。
3.until 引导的时间状语从句 (1)主句否定式的运用。 这要求我们要弄清主从句之间的逻辑关系,表示“直 到……”,主句用肯定句;表示“直到……才……”,主句 用否定句。如: ①We discussed the matter until the boss returned. 我们讨论这个问题一直到老板回来。 ②We didn’t discuss the matter until the boss returned. 直到老板回来我们才开始讨论这个问题。
before 从句中谓语动词不用否定式。如: Before they reached the station, the train had gone.他们 到火车站前,火车已开走了。
(2)since 引导的时间状语从句 A.时态问题。 since 引导时间状语从句,主句往往用现在完成时。如: Our hometown has witnessed great changes since he came to our village. 自从他来到我们村, 我们家乡的巨大变化是有目共睹的。
②The first time I climbed onto the wall, I felt nervous. 我第一次爬到墙上时,感到胆怯。 ③You’re welcome to come back any time you want to. 你想回来时随时可以回来。 ④Every time I catch a cold, I have a pain in my back. 我每次感冒背就疼。
②He came to our school last year, but it was/ had been three years since he had joined the football club in our school. 他去年来我校,但他参加校足球俱乐部已三年。
C.从句的理解。 当从句的动作是延续性动词且从句使用了一般过去时 时,它的语义应该是否定的。如: It’s many years since I enjoyed myself. 好多年我都没玩得这么开心过了。
在这一情况下,从句的动作一定是延续性动词,如果 是非延续动词,要用 when。如: Will you please take care of my house when I went away?
2.表示“一……就……”的时间状语从句 (1)the moment, the second, the minute, the time, the month/ week..., immediately, directly, instantly 都可引导时间 状语从句,相当于 as soon as,与一般将来时或一般过去时连 用。如: ①I’ll call you immediately I get to New York. 我一到纽约就给你打电话。 ②I recognized you the time/moment/second...I saw you. 我一见到你就认出了你。
6.before 和 since 都可引导时间状语从句。其区别是: (1)若表达“还未……就……”“不到……就……” “……才……”“趁还没来得及……”,要用 before。如: ①We had sailed four days and four nights before we saw land. 我们航行了四天四夜才看到陆地。 ②We hadn’t run a mile before he felt tired. 我们跑了还不到一英里他就累了。 ③Please write it down before you forget it. 在你还没有忘记之前把它记下来。
5.by the time 意为“到……时为止”,引导时间状语从 句时,如果谓语用一般现在时,其主句的谓语用将来完成时; 如果其谓语是一般过去时,主句就用过去完成时 By the time you come home next time, the building will have been finished. 到下次你回家的时候,这栋楼房就建起来了。
4. once 引导时间状语从句, 带有条件意味, 作“一旦…… 就……”;whenever 引导时间状语从句意为“无论什么时候 (=no matter when)”。 可以引导时间状语从句的还有: before, since,till,until 等 ①Once you have learned Spanish you will find Italian easy. 你一旦学了西班牙语,就会发现意大利语不难了。 ②Once you began you couldn’t stop. 你一旦开始就停不下来了。
when 可作并列连词用, 相当于 just then, at the time, 前一分句多用进行时、 be about to 或 be on the point of doing,表示“正在做……,就在这时发生了另外一件事”或 “届时”。如: ①I was reading when he suddenly came in. 我正在看书,这时他突然进来了。
(3)倒装句的问题。 not until 位于句首时,主句要倒装,其形式是部分倒装, 但如果用强调句,则不倒装。如: ①Not until he came back did he find his house had been broken into. 直到他回到家中,才发现他的家有人闯入过。 ②It was not until the fish in the river had died out that the villagers realized the importance of environment protection. 直到河里的鱼都死光了,村民们才意识到环保的重要性。
另外,the first time“第一次……”,the last time“最 后一次……”, any time“随时……”, all the time“总 是……”,each time“每次”,every time“每当……时”等 也可引导时间状语从句。如: ①Next time you come, do remember to bring your son here. 你下次来时,一定记住把你的儿子带来。
[答案] B
典例 3 —Why didn’t you tell him about the meeting? —He rushed out of the classroom ________ I could say a word. A. before C. when [解析] B. until D. after 句意:“你为什么没有告诉他这次会议
(3)while 强调主句动作发生在从句动作所发生的时间段 内,从句的动作必须是延续性动词。如: ①Strike iron while it’s still hot.趁热打铁。 ②Will you please take care of my house while I was away? 我外出时你能帮我看家吗?

状语从句
研习考纲重难点
状语从句的确定: 一般通过两句话之间有无句子成分的丢失来确定从句的的逻辑关系确定语意及相应的连词,最后作出正确的选择。
1.as,while,when 三个词在引导时间状语从句时,有 时间状语从句 以下异同 (1)as 强调主从句的动作同时发生,有 “一边……一 边……”的意思,也可说明两种正在发展或变化的情况,有 “随着……”的意思。如: ①He sang as he walked.他边走边唱。 ②As he gets older, he gets more open. 随着年龄的增长,他越发开朗起来。
(2)时态问题。 从句的动作发生在将来时,用一般现在时代替。如果从 句是将来完成时,用现在完成时代替;是过去将来时,用一 般过去时代替。如: ①The husband had left his key in his office. He had to wait until her wife came. 丈夫把钥匙落在办公室了,他不得不等到妻子回来。 ②Don’t get off until the bus has stopped. 直到车停下来再下车。
