宾语从句的句法功能

It all depends on whether it will be fine tomorrow.
3、作系表结构的宾语

宾语从句
宾语从句考点
1. 时态
2. 连词(引导词)
3. 语序
1. 主句时态为现在
2. 主语时态为过去
3. 特殊情况
1. that
2. if/whether
3. 特殊疑问词
陈述句
1. that引导的宾语从句
由that引导的宾语从句表示陈述意义。从连
词that无实际意义，不在从句中充当任何成。
I don’t think (that) there will be time to do it.
我认为没有时间做这件事了。
Many people believe (that) robots will do
most our work.
许多人相信机器人会做我们的大部分工作。
2. whether/if引导的宾语从句
whether/if引导的从句大多由一般疑问句直
接引语变化而来。whether/if在从句中不作，
但含有“是否”之义，在句中不可省略。
I ask them whether/if they would win the match.
Do you care whether/if you win
He asked me whether/if Miss Li was a teacher.
只用whether不用if的情况
①引导介词后的宾语从句时。
It depends on whether it will snow tomorrow.
I am interested in whether he likes English.
②与or not连用时。
I asked your secretary whether she could come or not.
Let me know whether he has passed the exam or not.
④有些动词，如discuss, doubt等后的宾语从句常用whether引导。
We’re discussing whether we should group these three companies.
I doubt whether he will keep his promise.
⑤宾语从句前置，置于句首时。
Whether they can come here on time, we don’t know.
Whether they will join in the camp, I don’t care.
③与不定式连用时。
I really don’t know whether to accept or refuse.
Next Monday the teacher will tell us whether to have a test.
在这里要注意, whether to do 在句中做宾语，并不是宾语从句。
3、疑问词引导的宾语从句
宾语从句可以由连接代词what, who, whom,
whose, which等引导，它们在宾语从句中充当
主语、宾语、表语和定语等，因此不能省略。
宾语从句可由连接副when, where, how,
why等引导，它们在宾语从句中作状语，不可
以省略。
Do you know who will come this afternoon
连词作主语
I don’t know whom you should depend on.
连词作宾语
I don’t know what it is.
连词作表语
Could you tell me which gate we have to go to
连词作定语
I wonder whose bike it is.
连词作定语
He didn’t tell me when the traffic accident had taken place.
连词时间状语
Your coat looks very nice. Could you tell me where you bought it
连词作地点状语
It is hard work. I wonder how you finished it in two days.
连词作方式状语
Please explain why you are late again.
连词作原因状语

连接代词一般表示疑问，但what除了表示疑

二、时态
宾语从句的时态
“宾从”时态怎么办？根据主句来判断；主句
现在，从随便；主句过去，从变换；“主从”动
词同发生，“过去进行”从句中；“宾从”动作先
发生，“过去完成”时态用；“宾从”动作后发
生，“过去将来”时态用；“宾从”表达是真理，
“一般现在”代“过去”。以上规则记心里，时态
呼应没问题。
主句现在，从随便
1. Mary says she _____________(come) back soon.
2. He says that he often ________ (play) football after school.
3. I hear that they _________________ (watch) a game now.
4. Do you know if he _____________(be) to Beijing ever
5. I don’t remember where he _________ (buy) the book yesterday.
will come
plays
are watching
has been
bought
主句过去，从变换
“主从”动词同发生，“过去进行”从句中；
He said that he was reading at that time.
“宾从”动作先发生, “过去完成”时态用；
I told him that I had had dinner already.
“宾从”动作后发生，“过去将来”时态用；
We thought that we would meet him soon.
“宾从”表达是真理，“一般现在”代“过去”

Everyone knew that there ______(be) sixty minutes in an hour.
goes
are
三、语序
所有从句中的语序都是陈述句语序，除倒装
句外。

2. Who will come to join us (Do you know)

3. My son has a cold. (she said)
She said that her son had a cold.
注意一下句子的语序。
Who went Beijing with you
What is the matter with you
What is wrong with you
What happened to you
上面的句子语序都是陈述语序，Who和what
是句子的主语。
1. 当主句的谓语动词是know, learn, forget,
remember, decide, ask, tell, show, teach等后面带特
殊疑问句转化的宾语时，主从句的主语也须一致这时
从句可以简化成“疑问词＋不定式结构”。
I don't know which sweater I should buy.
I don't know which sweater to buy.
Could you tell me how I can get to the park
Could you tell me how to get to the park
I haven’t decided whether I will go to the party.

2. 当句子满足一下条件，从句的否定往往体
现在主句中：
A: 主语是第一人称
B: 时态必须是一般现在时

think, suppose, guess, believe, expect,
consider。

3. 宾语从句中的虚拟语气
虚拟语气是一种动词形式，表示说话人的一
种愿望，假设，怀疑，猜测，建议等含义，虚
拟语气所表示的含义不是客观存在的事实。
建议 suggest 、advise、propose;
要求demand 、desire、request；
决定 decide; 命令 order、command、require;　坚决主张 insist;
等动词后跟宾语从句，用(should)+v

finished on time.
3. The boss ordered that all the employees

原因状语从句、结果状语从句
在这两种状语从句中，主从句之间的关系表
示因果关系。有时这两种从句可以相互转化。
原因状语从句: 从句说明主句动作发生的原因。
because, as, since
because表示直接原因， 语气最强， 最适合回
答why引导的疑问句。
I do it because I like it.
We went by bus because it was cheaper.
since引导的原因状语从句一般放于主句之前
表示已知的、 显然的理由(通常被翻译成“既然
” )，语气比because弱。
Since you are free today, you had better help me with my mathematics.
Since you don't trust him, you should not employ him.
Since you are grown up, you should not rely on your parents.
as 引导原因状语从句时表示附带说明的“双
方已知的原因”，含有对比说明的意味， 语气
比since弱， 较为正式， 位置较为灵活(常放于
主句之前)。
As it is raining, you’d better take a taxi.
As you are tired, you had better rest.
I went to bed early, as I was exhausted.
for连接的是并列句，不是复合句。表示前后
句之间的关系是原因关系，只提供一些辅助性
的补充说明。
He could not have seen me, for I was not there.
He seldom goes out now, for he is very old.
what for也可以用来提问原因
结果状语从句：从句说明主句动作发生的结果。

原因状语从句和并列句的转化
He didn’t come to work because he had a
bad cold.
表示因果关系的并列连词：for(原因), so(结果)
He didn’t come to work, for he had a bad cold.
He had a bad cold, so he didn’t come to work.
结果状语从句和简单句的转化
so… that (从句为肯定句)
= … 形/副 + enough + (for sb.) to do sth.
He is so old that he can go to school alone.
= He is old enough to go to school alone.
The question is so easy that I can do it.
=The question is easy enough for me to do.
当主从句主句不一致时，为了说明to do 动作的发出者，常在to do 前for sb.
so… that (从句为否定句)
= … too + 形/副 + (for sb.) to do sth.
The problem is so hard that I can’t work it out.
=The problem is too hard for me to work out.
=The problem isn’t easy enough for me to work out.
