状语从句 §

状语从句^{（Adverbial Clauses）}是一种用来修饰主句的从句，以一个句子做状语，表达描述性信息。它提供了关于时间、地点、原因、条件、目的、方式等方面的描述信息，以增加句子的复杂性和详细性。

类型	引导词	示例
时间状语从句	when ; while ; since ; as ; before ; till ; until ; as soon as …	I will call you when I get home.
地点状语从句	where	They went to the park where they used to play as children.
原因状语从句	beacause ; since ; as ; for …	He didn't come to the party because he was feeling sick.
条件状语从句	if;unless	If it rains tomorrow, we will stay at home.^主将从现
目的状语从句	so that … ; in order that …	She took extra lessons so that she could improve her English.
方式状语从句	like ; as ; as if…	He speaks as if he knows everything. ^{天上知道完，地下知一半}
结果状语从句 *	so/such … that … ; so that …(所以)	The one with the money got such a fright that he dropped the bag.
比较状语从句	than ; as	Tomorrow he will be watching her anxiously as she swims the long distance to England.
让步状语从句 *	though ; although ; even though ; even if …	for even though it was still summer, it rained continually and it was often bitterly cold.

这些副词引导的从句可以在主句之前、之后或中间出现，具体位置取决于句子结构和所要表达的含义。

If 条件状语从句 ^{(If + 从句，主句)}

If + 从句 ^{如果A从句}	主句 ^{那么就B主句}
If he is sleeping,^{从句：如果他在在睡觉，}	don't wake him up. ^{主句：不要叫醒他}
if you don't hurry^{(条件,你再不快点的情况下).}	You will miss the train^{(主句,你将会错过火车),}
You can post these letters if you want to. ^{主句、从句位置可以互换} If it’s fine tomorrow, we can/may go out. ^{从句 + 主句} Please let me know if you cant’t come. ^{主句 + 从句}

if 引导的条件从句指能够发生、可能发生或可能发生过的事件。如果认为将来的事件很可能会发生^{(真实条件句)}，那么 if 从句中要用一般现在时^{（有时也用其他形式的现在时）}，主句中用 will^{（或 shall）}加动词形式或其他形式的将来时。
条件句的主句中的 will 表示肯定如此或几乎可以肯定会如此。如果觉得其“肯定”程度达不到使用 will 的程度，或者如果想表达建议等其他意思，就可以用别的情态助动词来代替 will；条件句中的主句还可以用祈使语气等表示请求、建议等。

* 真实条件句/虚拟条件句

格式	真实条件句		虚拟条件句
形式	零条件句	If +从句 ^(现在时)，主句^(现在时)	二型条件句	If + 从句^(过去时)，主句 ^{would/could/might + 动词原形}
说明		表达普遍真理或事实		表达与事实相反的情况或不太可能发生的情况
关键字		always, usually, often, sometimes, if		if, wish, were, had
例句		If it rains, the ground gets wet.		If I had a million dollars, I would travel the world.
形式	一般条件句	If + 从句 ^(现在时)，主句^(将来时)	三型条件句	If + 从句 ^{(过去完成时)}，主句 ^{would/could/might + have + 过去分词}
说明		表达可能发生的情况		表达对过去事件的遗憾、虚拟的情况以及无法改变的事实
关键字		when, unless		should, could, might
例句		If it rains tomorrow, I will stay at home.		If I had studied harder, I would have passed the exam.
形式			混合条件句	If + 从句 ^{(过去完成时)}，主句 ^{would/could/might + 动词原形}
说明				表达对过去事件的影响在现在的结果。
关键字				should, could, might
例句				If it hadn't rained, we would be having a picnic now.

一般现在时	一般将来时
If he is out,^{假设现在，} If he is working,	I will call him tomorrow.^描述将来 I won't disturb him.
we will stay at home. ✓ ^描述将来	If it rains tomorrow,^假设将来
~~If it will rain tomorrow, we will stay at home.~~ X ^{真实条件句假设将来描述将来，主将从现}

英文里的特殊规则在真实条件句里，要假设将来，还是得需要使用^(从句)一般现在时 + ^(主句)一般将来时。

一般过去时	过去将来时
If tall chimneys were built above sea level § ,^假设过去	the tunnel would be well-ventilated.^{描述过去将来}

规律总结：If 假设过去使用过去时，假设现在使用现在时，假设将来也是使用的现在时，但主句要成立则全部为相应的将来时。

真实条件句	IF从句	主句	使用率
假设过去	过去的各种时态	过去将来时	5%
假设现在	现在的各种时态	一般将来时	5%
假设将来	一般现在时^{(替代将来)}	一般将来时	90%

误解“主将从现”，即遇到条件句主句为一般将来时，从句使用使用一般现在时只是大多数的情况，并不是绝对的情况。要根据上下文灵活使用。

I shall see him, if he is here next week. ^主将从现
If he plays well, he will get into the school team.^主将从现
If they have time the day after tomorrow, they will fly to London to have a meeting with us.^主将从现
If you make a mistake, correct it. ^祈使句
If you like him, you may tell him. ^情态动词
If she enjoys concerts, why doesn't she come with us? ^疑问句

顺序问题：If 引导的是条件从句，要实现的是主句，所以不管是If在句首还是句中，它总是引导的是从句。

If you park your car in the wrong place, a traffic policeman will soon find it. ^{如果你把车停在错误的地方，交通警察不久将会找到它。}
A traffic policeman will soon find it , if you park your car in the wrong place. ^{【倒着翻译】}

let	let	let	letting

have a finger in every pie. ^{参与每件事}
