语法知识归纳：宾语从句宾语从句在复合句中作主句的宾语。

由连接词+ 主语+ 谓语构成

常由下面的一些词引导：

㈠由that 引导表示陈述意义that 可省略

He says (that) he is at home. 他说他在家里。

㈡由if , whether 引导表示一般疑问意义(带有是否、已否、对否等)

I don’t know if / whether Wei Hua likes fish.

我不知道韦华是否喜欢鱼。

㈢由连接代词、连接副词(疑问词) 引导表示特殊疑问意义

Do you know what he wants to buy? 你知道他想要买什么吗？

㈣从句时态要与主句一致

当主句是一般现在时，从句根据情况使用任何时态

He says (that ) he is at home. 他说他在家里。

I don’t know (that) she is singing now. 我不知道她正在唱歌。

She wants to know if I have finished my homework.

她想要知道我是否已经完成了我的作业。

Do you know when he will be back? 你知道他将会什么时候回来？

当主句是一般过去时，从句应使用过去某时态(一般过去时,

过去进行时，过去将来时，过去完成时)

He said (that) he was at home. 他说他在家里。

I di dn’t know that she was singing now. 我不知道她正在唱歌。

She wanted to know if I had finished m homework.

她想要知道我是否已经完成了我的作业。

Did you know when he would be back? 你知道他将会什么时候回来？

三、重点句型解读：

1．What would you do if you had a million dollars ?

用法：if引导的虚拟的条件状语从句，从句为非真实条件句。非真实条件句是指假设的条件与事实相反或不可能实现。当虚拟语气与现在事实相反时，从句用一般过去时。主句用should /would/could /might + 动词原形。

1)If I had time , I would go for a walk. _____________________

2)If I were invited , I would go to the dinner party.（翻译）

___________________________________________

3)If I won a million dollars in the lottery, I would put it in the bank.

__________________________________________

2. He doesn’t know if he should bring a present.

用法：1）此处if 表示“是否”，相当于whether ，引导宾语从句。

2)should 此处表示“ 应该”，不是用来表示虚拟语气。

拓展：if 作“是否”讲，引导宾语从句，从句可以用一般将来时或其他时态。

if 作“如果”讲，引导条件状语从句，从句用一般现在时代替一般将来时。

（翻译）

1) I don’t know if I should go to the party.

______________________________

2) He doesn’t know if we will arrive on time tomorrow morning.

_____________________________________________________

3)If I have enough money next year, I will go to England.

3. I don’t have a present , what if everyone else brings a present ?

____________________________________________________

用法：what if 表示“如果…，怎么办？要是…又怎样？”相当于

What would happen if … ?

Eg: 1) What if it’s true ?___________________________

2)What if aliens should come to the earth ?___ _______________

本单元语法学习：

if 引导的非真实性条件状语从句即虚拟语气

通过动词形式的变化来表示说话人对发生的动作或存在的状态所持的态度或看法的动词形式称为语气，虚拟语气表示说话人所说的

话不是事实，而是一种祝愿，建议或是与事实相反的假设等。

If 引导的条件状语从句分为真实和非真实条件句，非真实条件句应用虚拟语气。如果要表示与现在或将来事实相反时，其虚拟语气结构为：句型条件从句主句

谓语动词形式动词过去式(be动词用were)would+动词原形

即：(从句)if +主语+动词过去式(be 动词用were), 一般过去时

(主句) 主语+would+动词原形过去将来时

如：If I had time, I would go for a walk.

如果我有时间，我就会去散步。(事实上我现在没有时间)

If I were you, I would take an umbrella.

假如我是你的话，我会带上雨伞。(事实上我不是你)

I would say no if someone asked me to be in a movie. 假如有人请我当电影演员，我

会表示拒绝。(事实上瑞没有人请我当电影演员)

练习：If I were you, I should stay at home. 翻译_____________________

If I had time , I would go for a walk . 翻译_____________________

2.. 有时句子中的虚拟条件不一定都带有明显的虚拟条件从句，而是利用某

些短语或并列从句来表示；

Without your help he could not do it . 翻译_____________________________

I would feel sorry without giving you a present

特殊句型:

1.What would you do if your brother borrowed your clothes without permission ?

注意：borrow 是动词，意为“借入、借用”，表示“从……借”时，其后常跟介词from 。

I borrowed a book from my friend. 翻译：________________________

辨析: borrow , lend与keep

Borrow 表示主语借进，常用于borrow sth. from sb. 结构。

He borrowed some money from me this morning.

Lend表示主语“借出”，常用于lend sb. Sth. 或lend sth. to sb. 结构。

例如：Could you lend me some money ? = Could you lend some money to me ? keep在表示“借”的意思时，通常表示“借某物多长时间”，多接for 短语。

例如：---- How long can I keep the book ?

---- You can I keep it for a week .

注意：borrow ,lend 都是短暂性动词，不能和表示时间段的状语连用，要接时间段用keep 。

2.You would rather stay at home and read a good book than go to a party.

你会宁愿待在家里读一本好书而不愿去参加聚会。

句式：would rather do … than do… .= had rather do …than do…是固定用法，意为“宁可……（也）不愿……，与其……不如……”通常简写为’d rather do

注意：在would rather… than… 这个结构中，必须注意前项和后项的对称，即than 后所连接的词必须与前面的词在词性和结构上相一致。

例如：I’d ra ther have the red one than (have ) the green one.

我宁愿买这个红色的，而不是那个绿色的。

邀请: invitation n. 例如：Thanks for your invitation

自我测评：

1.Do you have experience _____ (deal ) with this problem ?

2.It’s very kind of you . Thanks for _____ ( invite ) me to your party.

虚拟语气的其他用法：

.虚拟语气用于wish后的宾语从句：a. "wish+宾语从句"表示不能实现的愿望,汉语可译为"可惜…"、"……就好了"、"悔不该……"、"但愿…"等。表示与现

在事实相反，从句的谓语动词用过去式;、例如: I wish I remembered her addres.
