1. when、as、while引导的时间状语从句分析：(1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用延续性动词又可用非延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。
注意体会如下例句：I’ll call you when I get there. 我一到那里就给你打电话。
// When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。
// He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。
// When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。
如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。

状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。
其位置一般放在句末，但也可放在句首或句中。

考点三、状语从句与非谓语动词之间的替换；考点四、根据从句与主句的逻辑关系选用从属连词；三、时间状语从句详解1.引导词（1）基本类：before ,after ,when ,while ,as ,since ,till ,until ,once ,as soon as.（2）名词类：（由名词词组充当引导词）the moment ,the minute ,the second ,the instant ,(一…就…)every time ,each time ,the first time ,the last time（3）副词类：（由副词充当引导词）immediately ,directly ,instantly (一…就…)（4）句型类：no sooner…than…,hardly/scarcely…when…（一…就…）2.引导词具体讲解：当…时候：It was six o’clock when I got home.Sb was doing sth when…1)when 这时Sb was about to do sth/was on the point of doing sth when…Sb had just done sth when…既然: It was foolish of you to take a taxi when you could walk there in five minutes.既然你能5分钟就走到那儿，再搭出租车真是太傻了。
当…时候(引导持续性动作): He fell asleep while he was reading a book.2) while 然而(用于句中) : He likes pop music while I am fond of folk music.虽然,尽管(用于句首) While volleyball is her main focus, she’s also great atbasketball.当…时候;随着He smiled politely as Mary apologized for her drunken friends.3) as 因为You can’t continue with the training as you have n’t recovered from the injury.尽管Hot as/though the night air was, we slept deeply because we were so tired after the long journey.正如,正像The air quality in the city, as is shown in the report, has improved in thelast two months.肯定句:主句的谓语动词必须是延续性动词。
He worked until late into the night.4)till, until否定句：主句的谓语动词是非延续性动词。
★not…until 的倒装句式和强调句式He didn’t consider having a holiday until he retired from teaching three years ago.倒装句式：Not until he retired from teaching three years ago did he consider having a holiday.强调句式：It was not until he retired from teaching three years ago that he considered having a holiday.5) before 在…之前,….才We had sailed four days before we saw land.还没来得及Before I could get in a word, he had measured me.★It was +时间段+before sb did sth…(…才)★It will be+时间段+before sb does sth (…才)It was two weeks before we met again.两周之后我们才见面。
It will be two weeks before we meet again. 我们再过两个周才能见面。
6) since 自从… She has been working in this factory since she left school.既然Since Babara is no longer my wife, I’m no longer responsible for her debts. 既然芭芭拉不再是我的妻子，我也不用再负责她的债务了。
★It is/ has been +段时间+ since sb did sth…（自从…以来多长时间）7) 关于一…就…的表达方式：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner…than…, hardly/scarcely…when, once 一…就…Hardly had I got home when it began to rain. 我刚一到家就开始下雨。
No sooner had I got home than it began to rain.8)每次…；每当…;下次…等表达方式：every time, each time, next time, the last time, any time, all the time 等名词短语用来引导时间状语从句。
Every time I was in trouble, he would come to help me out.9) 几个极易混淆的时间状语从句：1）It was +时间点+when…（当….的时候时间是….）It was 5 am when we arrived at the village.2）It was/will be+时间段+before…(没过…就／过了…才)It was/will be two weeks before we met/meet again.3）It is /has been +时间段+since…（自从…以来有…）It is/has been 3 years since we last met.★突破点：一看be动词的时态，二看时间段还是时间点。
3.时间状语从句和强调句的区别强调句的句型是：It is (was) 被强调部分+ that (who) + 句子其他部分It was seven o'clock when we reached the station.（状语从句）=It was "at" seven o'clock "that" we reached the station.(强调句，定语从句）强调句和时间状语从句的区别是：时间状语从句可以去掉，不影响句子的完整性。
而强调句that/who引导的句子是不能去掉的，否则句子就不完整了，单独的“It was at seven o'clock”是错误的。
(四)It is(was)+时间点+that的强调句型强调句仅是形似，与“when”句型的比较很明显：1. 强调句时间点部分通常带有介词或后面有副词；2. 去掉it is(was)……that之后，句子整合成一个完整的句子。
Eg:①It was in the morning that I was robbed in the street. （删除后还原：I was robbed in the street in the morning.）=It was this morning that I was robbed in the street.②It was at 7:00 that I met Tom this morning. （删除后还原：I met Tom this morning at 7:00.）=It was 7:00 when I met Tom this morning4.关于时间定语从句和时间状语从句的区别时间状语从句和定语从句的区别其实跟上面说的是一样的，强调句型其实就是一种特殊的定语从句。
本身最简单的表达法是：We reached the station at seven o'clock.强调句It was "at seven o'clock" that we reached the station（为了强调"at seven o'clock"）同时它也是定语从句：从句“that we reached the station”修饰的是it=the time.也就是说关键是看前面有没有先行词，有就是定语从句，没有就是时间状语从句。
如：1.By the time when you arrived in Beijing, we had stayed there for two weeks.有先行词the time 那么when you arrived in London就是定语从句2.when you arrived in Beijing, we had stayed there for two weeks.没有先行词when you arrived in London就是时间状语从句。
