比较状语从句也可以说是方式状语从句的一种，两者拥有很多相似之处，容易令人混淆，但在意思表达方面又有着很大的不同，这是学习者们必须注意的地方，所以这次沪江小编就来为大家比较一下这两者的相似与不同吧。 比较状语从句与方式状语从句比较： 一. 比较状语从句 引导比较状语从句的从属连词为 as...as，not as/so...as，than，the more...the more 等等，这些都是用来进行比较对比，并且通常会与比较级最高级等连用。 eg. The work is not so difficult as you imagine.       这个工作不像你想的那么难。       He is as handsome as that film star.       他跟那个电影明星一样帅。      The more you study, the more knowledge you can get.       你越学习就越能懂更多。 二. 方式状语从句 引导方式状语从句的从属连词有as，as if 或 as though等, 但和比较状语从句不同，方式状语从句的“像”“如同” 并不是表示单纯的比较，而是带有比喻或者依照的含义。 eg. Do as I told you.       按我告诉你的那样做。      I remember the whole thing as if it happened yesterday.       整个这件事我记得很清楚，就仿佛是昨天发生似的。      As water is to fish, so air is to man.      我们离不开空气，犹如鱼儿离不开水。 * 口语中like也可用连词引导方式状语从句。 eg. Do it like I do. 照我这样做。       I can’t dance like she does. 我没她舞跳状语从句也可以说是方式状语从句得好。 以上就是比较状语从句和方式状语从句的对照了，大家看明白没有？从例句中可以看出这两种状语从句有相似的引导词，翻成中文后意思的差别非常微妙，所以除了用英语思维来思考判断句子外，各位学习者们也要联系上下文和语境来进行一个句子类别的判断。

以是短暂的。 如：   Sometimes I watch TV as I am having breakfast．   4）when和while还可以是并列连词，意思分别是“就在这时”，“然而”。 如：   I was having a rest on the sofa when the telephone rang．   They were surprised that a child should work out the problem while they couldn’t .   注：并列连词when常用与以下句型中：   ①…was/were doing…when…（正在做…突然）    ②…was/were about to do…when…（刚要做…突然）   ③…was/were on the point of doing…when…(刚状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。 下面是着重为大家讲解：时间状语从句要做…突然)   ④…had just done…when….(刚一…就)   ⑤Hardly/Scarcely had…done…when…(刚一…就)    好了，以上就是关于时间状语中when, while, as区别的介绍，还请大家在平时勤加练习。

用表示时间的连词连接一个句子作状语，这样的主从复合句叫做时间状语从句（adverbial clause of time）。连接时间状语从句的连接词有when、before、after、while、as soon as、until、since...... 今天小编就就结合一些例句来为大家讲解一下这些从属连词的意义与用法。 Before“在…之前”，引导时间状语从句时，表示主句动作发生在从句动作之前。 Check your paper carefully before you hand in. 交卷前要仔细检查。（主句为检查试卷，发生在从句交卷之前） 与before 相反，after引导时间状语从句时，表示主句动作发生在从句动作之后，意为“在…之后”。 I went to bed after I finished my homework. 完成作业以后，我才上床睡觉。（主句为上床睡觉，发生在从句完成作业之后） 另一个常见的引导词为when，在引导时间状语从句时意为“当…时候”，while也可表示此意，但后者引导的从句谓语动作必须是延续性的，并强调主句和从句的动作同时发生，并且while有时还可以表示对比。 When I lived in the countryside, I used to climb trees with my friends. 在我住在乡下的时候，我经常和小伙伴们一起爬树。 She stared at me while I dance yesterday. 昨天我跳舞的时候，她盯着我看。（她盯着我看与我跳舞同时发生） Tom is a quiet boy while Jack is a naughty guy. Tom是一个安静的男孩，而Jack则很淘气。（安静与淘气形成对比） 在时间状语从句中，其它常见的引导词还有很多，例如till、until、since、as soon as、by the time等，还有一些不常见的用来连接主从句的结构，这里小编就不一一列举了。本文详述的四个引导词在时间状语从句中最为常见，也比较容易成为考点，希望同学们加强记忆。

常用的引导词。 ③ according as：“根据，取决于....” 使用这个引导词时，前后需一一对应 eg.You will be awarded or blamed according as the outcome of your reasearch is good or bad.      你被表彰还是被谴责取决于你研究结果的好坏。 ④ in proportion as：“成正比..../ 越.....就越.......” ，引导词前后都使用正常语序 eg.Men are happy in proportion as they are virtuous.      人的快乐与德行成正比。     Some people are happy in proportion as they are noticed.      有些人越被瞩目就越开心。 ⑤ The most…in/of eg.She is the most beautiful in her class. ⑥ the + 形容词+est…of/in eg.This school is the best school of our city. ⑦ no more than : 带有嫌少的意思 eg. I have no more than ten dollars. ⑧ not more than：表示前者不如后者 eg. Mary is not more pretty than Cathy. ⑨ one of the + 名词(复数)....in...... eg. Shenzhen is one of the most developed cities in China. 以上就是小编为大家整理的引导词了，不知道大家有没有记住呢？希望大家在学习的过程中不要光看光背，而是要懂得如何灵活地应用起来，可以根据例句来尝试仿写，写多了自然就熟悉了，这样才算状语从句得上是真正将知识吸收了。

除了常见的几种搭配外，结果状语从句还有着其他一些长期以来约定俗成的连词搭配，并且除了常用连词外，在一些特殊情况下结果状语从句也可以用其他特殊的结构来表示。这次沪江小编就和大家一起来学习一下这些特殊状况。 一. so与表示数量的代词many、 few、much、little等连状语从句用是常见固定搭配，并且so绝对不能替换成such。 1. so+many/few（+复数名词）+that eg. There are so many toys that the boy don't want to leave. 2、so+much/little（+单数不可数名词）+that eg. There is so much contradictory advice about this project that I become confused. 二. that也可以直接用来连接结果状语从句。 eg. What have we done that you should be so angry with us? （我们做了什么使你这么生气？） 三. 如果结果状语从句的主语与主句的主语相同， 可用so as to取代该结果状语从句。 eg.He was such a kind people that he phone for a taxi for the patient.      He was so kind as to phone for a taxi for the patient. 四. 在结果状语从句主从句主语一致的情况下，可省去从句主语，从句谓语变非谓语。这时，如果从句是肯定句，那么so就要换为enough。如果从句是否定句，那么so就要换成too。 eg.He is so old that he can't go to school.= He is too old to go to school.     He is so old that he can go to school.= He is old enough to go to school alone. 以上就是沪江小编为大家总结整理的结果状语从句的几种特殊情况了，大家都学到了没有呢？其实这几种特殊情况在实际中出现率也很高，并且规律性也强，所以大家只要通过例句来吃透规律，就能慢慢掌握了。

要你保证不告诉任何人，我就把这个秘密讲给你听。      Provided [Providing] that you keep quiet, you can come to the concert. 只状语从句和其他从句要你保持安静，你就可以去听音乐会。      Providing there is no opposition, we shall hold the meeting here. 如果没人反对我们将在这里开会。 这类从句通常置于主句之前，但置于主句之后也是可能的。 eg.I will stay here provided [providing] the climate agrees with me. 如果这里的气候合适的话，我就待下来。      You can borrow my bike providing [provided] you bring it back. 你可以借我的自行车，只要你还给我。  以上就是关于特殊引导词的知识点了，掌握好这些特殊引导词，不仅能够让你在考试中更有优势，更能让你在日常交流中更显地道自然，一起加油学习吧！

行时：this morning, the whole morning, all day, yesterday, from nine to ten last evening… when, while 将来进行时：soon, tomorrow, this evening, on Sunday, by this time, tomorrow, in two days, tomorrow evening 以上就是小编为大家带来的时间状语从句中时态与连词的搭配用法了，不知道大家看懂了没呢？说实话，这么多连词，这么多时态，小编在整理的时候也是非常晕头转向的，但是仔细看看就会发现这些全是日常生活中状语从句，顾名思义，时间是最重要的，而时间则通过时态的使用来表达，时态一错，整个句常见常用的单词，只要根据语法规律对号入座就行，所以大家也不妨在平常的英语使用中多留意留意这个方面。
