主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。

虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。

Were they here now, they could help us.

=If they were here now, they could help us.

Had you come earlier, you would have met him

=If you had come earlier, you would have met him.

Should it rain, the crops would be saved.

=Were it to rain, the crops would be saved.

注意：

在虚拟语气的从句中，动词'be'的过去时态一律用"were"，不用was， 即在从句中be用were代替。

If I were you, I would go to look for him.

如果我是你，就会去找他。

If he were here, everything would be all right.

如果他在这儿，一切都会好的。

典型例题

_____ to do the work, I should do it some other day.

A. If were I　　 B. I were　C. Were I　D. Was I

答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do.

当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.

当主句为过去时

①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生

②从句过去完成时表示该动作发生在主句谓语动作之前

③从句谓语用过去将来时表示该动作发生在主句谓语动作之后

④如果从句是一个客观真理，那么从句的时态不根据主句的时态而变化

⑤当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时，不能按正常语序安排，经常将这类引导词置于句首

无论任何时候都为陈述语序.但也有部分口语提问例外 E.G:What's the matter?What's wrong with you?

一般现在时、一般过去时用be +及物动词的.过去分词，be有人称、时、数变。

完成时态have(has)done，被动将been加中间。

一般将来shall(will)do，被动变do为be done。

将来进行无被动，shall(will)be doing。

现在完成时，被动 have(has)been done。

现、过进行be doing，被动be加being done。

情、助、有、是妥安排，一律随新主语变。

否定助后加not，疑问一助置主前。

主语恰是疑问词，直陈语序主在前。

一般情助加be done，双宾多将间宾变。

复合宾语宾变主，宾补、主补相应变。

第二句“be有人称、时、数变”即be有人称、时态和单、复数的变化。“情助”是指情态动词和助动词“must，may，can，shall，will”等一律随新主语(多是主动句中的宾语)来变化。“疑问一助置主前”是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。

宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词 (及物动词) 或介词之后。

1. 作动词的宾语

(1) 由that引导的宾语从句(that 通常可以省略)， 例如：

I heard that be joined the army. 我听说他参军了。

(2) 由what, whether (if) 引导的宾语从句，例如：

a) She did not know what had happened.　她不知道发生了什么。

) I wonder whether you can change this note for me.　我想知道你是否能帮我改一下笔记。

(3) 动词+间接宾语+宾语从句。例如：

She told me that she would accept my invitation.　她对我说她会接受我的邀请。

2. 作介词的宾语，例如：

Our success depends upon how well we can cooperate with one another.　我们的成功取决于我们之间的合作。

3. 作形容词的宾语，例如：

I am afraid (that) I've made a mistake.　我恐怕我已经犯了一个错误。

注意：that 引导的从句常跟在下列形容词后作宾语：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。

4. it 可以作为形式宾语

it 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如：

We heard it that she would get married next month. 我听说她下个朋就会结婚了。

5. 后边不能直接跟that 从句的动词

这类动词有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。如：

正确表达：I admire their winning the match.

错误表达：I admire that they won the match.

6. 不可用that从句作直接宾语的动词

有些动词不可用于“动词+间接宾语+that从句”结构中，常见的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：

正确表达：He impressed the manager as an honest man.

错误表达：He impressed the manager that he was an honest man.

7. 否定的转移

若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：

I don't think this dress fits you well. 我认为这件衣服不适合你穿。

表语从句

表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语+连系动词+表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如：

1) The question is whether we can make good preparation in such a short time.

2) This is why we can't get the support of the people.

3) But the fact remains that we are behind the other classes.

4) The reason he is late for school is that he missed the early bus.

同位语从句

同位语从句就是在复合句中作名词的同位语的名词性从句。

1. 同位语从句的功能

同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：

1) The king's decision that the prisoner would be set free surprised all the people.

2) The order that all the soldiers should stay still is given by the general.

2. 同位语在句子中的位置

同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：

He got the news from Mary that the sports meeting was put off.

3. 同位语从句与定语从句的区别

(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分(主语或宾语)，而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。

(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征;同位语从句是名词性的，其功能是对名词进行补充说明。例如：

1) The news that he told me is that Tom would go abroad next year.(他告诉我的消息是汤姆明年将出国。)(第一个that引导的从句是定语从句，that在从句中作宾语)

2)The news that Tom would go abroad is told by him.(汤姆将出国的消息是他讲的。)(同位语从句，that在句中不作任何成分)
