完整版)初中状语从句考点归纳

状语从句是指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。

时间状语从句常用when。as（当。时候）。while。before。after,since。till。until。as soon as等连词来引导。例如：在来中国之前，他学了一点汉语。他初中毕业后，去了一家工厂工作。在时间状语从句里，主句用将来时态时，从句通常不用将来时态，用现在时态表示将来的动作或状态。例如：我到纽约后会给你打电话。他回来时，我会告诉他一切。他不亲眼看到，是不会相信的。在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”,“在……以前不……”,谓语动词可用瞬间性动词。

条件状语从句通常由if。unless(除非)引导。例如：如果明天下雪了，我们该怎么办？除非我告诉你，否则不要离开建筑物。

2.条件状语从句

在条件状语从句中，谓语动词通常使用现在时态表示将来的动作或状态（即主将从现）。例如：

如果我明天有空，我会帮你学英语。

除非他生病了，他不会迟到。

祈使句+ and (or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。例如：

快点，否则你会迟到。

努力研究，你就能通过考试。

3.原因状语从句

原因状语从句通常由because、since和as引导。例如：

他因为生病了，所以没有来上学。

因为下雨，我们不去动物园了。

你回答不了这个问题，所以我会问别人。 因为表示直接原因，语气最强，多放在主句之后。而as和since语气较弱，一般用来表示明显的原因，放在句首。例如：

你为什么不去那里？

因为我不想去。

他没有车，所以不能轻易到达那里。

因为我们没有钱，所以不能买它。

因为和so不能同时出现在一个句子中。

4.结果状语从句

结果状语从句由XXX和XXX引导。例如：

他太穷了，以至于不能给儿子买自行车。

她是一位好老师，以至于每个人都喜欢她。

XXX cases。such as in result XXX clause introduced by so。the word so is an adverb that is used with an adjective or adverb

and followed by that and a clause。For example。"XXX ever see

her." In a result clause introduced by such。the word such is an

adjective that can modify a XXX or not。and if it is a singular

countable noun。it needs an indefinite article a or an。For

example。"It was such a hot day that nobody wanted to do anything." Sometimes。the two structures can be interchangeable。as in "It was such a wonderful film that all of us wanted to see it

again" and "The film was so wonderful that all of us wanted to see

it again." Another example is "It is such an important match that

nobody wants to miss it" and "The match is so important that

nobody wants to miss it."

When a noun is modified by words such as many。much。little。or few。only so can be used in the result clause。For

example。"Soon there were so many deer that they ate up all the

wild roses" and "He has so little time that he can't go to the cinema

with you."

Comparison XXX such as as。as (or the negative not so/as。as) or comparative adjectives followed by than。For example。"Tom runs faster than John does" and "This classroom is as big as

that one."

XXX such as so that。in order that。or lest。They indicate

the purpose of the n in the main clause。For example。"He studied hard so that he could pass the exam" and "XXX she wake

up the baby."

He was reading a book when the phone rang.

2.while只能指"时间段"，与延续性动词连用。如：

While I was studying。XXX.

注意：不要把while和when混淆，造成语法错误。

改写：

1.目的状语从句通常由so that或XXX引导，例如：我们早早出发是为了赶上第一班火车。他努力研究是为了将来工作更出色。我们使用电脑是为了节省时间。

2.so that既可引导目的状语从句，也可引导结果状语从句。区别这两种从句的方法有两个：一是目的状语从句里往往带有情态动词can、could、may、might等；二是从意思上看，目的状语从句往往表示的目的很明确，例如：说话清晰是为了让他们能听懂（目的状语从句）。XXX病得很重，以至于他必须休息（结果状语从句）。

3.让步状语从句通常由although或though等连词引导，例如：虽然他很年轻，但知识很渊博。虽然我很累，但我必须继续工作。 4.although（though）和but不能用在同一个句子中，例如：虽然下大雨，但他仍然出去了，而不是“虽然下大雨，但他仍然出去了”或“下大雨，但他仍然出去了”。

5.地点状语从句常常由where引导，例如：去你喜欢的地方。有志者事竟成。

6.while和when的区别：when既可以指时间点，与瞬间动词连用，也可以指时间段，与延续性动词连用（相当于while）。例如：他进来时，他妈妈正在做饭。电话响时，他正在看书。XXX只能指时间段，与延续性动词连用。例如：我在研究时，我的室友在看电视。不要混淆while和when，以免造成语法错误。

library。It's important to note that when using "while" to indicate a

time d。the verb in the while clause XXX。"XXX."

indicate a direct XXX "why." "As" is used to explain a reason and

emphasizes the main clause。XXX as "due to." "Since" XXX as

"since." For example。"Water is very important because we can't live without it." "He didn't XXX." "I'll do it for you since you are
