表示动作发生的时间，地点，原因，方式，目的，条件，比较，让步等等的就是从句。用来做状语的从句，就是状语从句。状语的内容太多，今天只学习时间状语。
一，副词和介词短语做状语，说明动作发生的时间或状态。
Tom finished writing homework at night.他是晚上完成家庭作业。They came late yesterday.他昨天晚上来晚了。The grandmother has lived in the countryside since 2020.这位奶奶从2020年到现在一直和她的女儿住在乡下。Mary arrived home at eleven o'clock. 玛丽11点回到家的。We have a meeting on Monday. 我们星期一开会。We have been swimming since nine o'clock this morning.从今天早上九点到现在我们一直在游泳。My father worked until ten o'clock last night.我爸爸昨天晚上工作到10点钟。As a child, he had to work with his father.小时候，他就不得不和爸爸一起干活了。Then he went to a city with his friends.后来，他和朋友一起去了一个城市。二，表示时间的引导词构成的时间状语从句
When Tom came back, he was tired.汤姆回来的时候，就很累了。After he had finished his work, he went to bed.他完成了作业之后才睡觉的。By the time we arrived at the station, the train had left.当我们到达车站的时候，火车已经走了。I'll tell him about it as soon as he comes back tomorrow.每天他一回来，我就告诉他此事。They waited until the rain stopped.他们等到雨停。We won't leave until the rain stops.我们要等到雨停再走。Before I went to college, I had studied at this school.我上大学之前在这所学校读过书。By the time you get to the station, the train will have left.等我们到达车站的时候，火车将已经离开了。I have been able to swim since I was 12 years old.我从12开始，就一直会游泳了。We were about to leave when it began to rain.我们正要出门，天就开始下雨了Hardly had we arrived home when my aunt came.我们刚好到家，我的阿姨就来了。（倒装句）No sooner had he finished the homework than his father came back.他刚完成作业，父亲就回来了。（倒装句）It was at nine o'clock that he came back home last night.昨天晚上他是九点钟才回来的。（强调句，强调时间状语）It was not until he finished homework that he went to bed.他是完成作业后才睡觉的。（强调not until...）By 2027, she will have finished all her courses. 到2027年，她将会完成所有课程的学习。因此，很多时间副词和介词短语，直接做状语，说明动词发生的时间。在状语从句中，一定要注意主句和从句里谓语动词时态变化。
今天推荐几种小蜜蜂、耳机和其它实用的宝贝，喜欢的就带上，谢谢。
