  • 过去将来时
  • 宾语从句
过去将来时:
表示从过去的某一时间来看将来要发生的动作或存在的状态。过去将来时常用于宾语从句和间接引语中。
去将来时的出发点是过去,即从过去某一时刻看以后要发生的动作或状态。

过去将来时表达法:
1. would+动词原形
  例如:When you asked Li Lei for help, he would never refuse you.
2. was/were going to+动词原形
  例如:He told ustaht he was going to attend the meeting.
3. was/were to+动词原形
  例如:Li Lei was to arrive soon.
4. was/were about to+动词原形
  例如:We were about to leave there when it began to rain heavily and suddenly.
5. was/were+现在分词
  例如:He was leaving the next day.

句型结构
肯定句:主语+be(was,were)going to+动词原形~.
否定句:主语+be(was,were)not going to+动词原形~.
疑问句:Be(Was,Were)+主语+going to+动词原形~?

肯定句:主语+would(should)+动词原形~.
否定句:主语+would(should)not+动词原形~.
疑问句:Would(Should)+主语+动词原形~?
过去将来时的构成和一般将来时一样,只不过把助动词be变为过去式,把will,shall变为过去式。
例句:I didn''t know if he would come. =I didn''t know if he was going to come. 我不知道他是否会来。


过去将来时具体用法:
一、would+不定式
1.用“would+不定式”表示过去将来时间通常带有表示过去将来的时间状语,而且多见于从属分句。
He said he would come back the next day.
2.如果要表示在过去将来某一时间正在进行得动作,可用“would+不定式进行体”。
例如:He never imagined that some day he would be living away from his motherland.
这种“would+不定式进行体”结构也可能仅仅表示一般过去过去将来时间,如同“will/shall+不定式进行体”表示一般将来时间一样。、
例如:He told me that Mary would be coming the next day.
如果要表示在过去将来某时以前业已发生得事态,可用“would+不定式完成体”。
例如:The delegation would have arrived by four o'clock that afternoon.
如果要表示从过去某时开始一直延续到过去将来某时得动作或事态,可用“would+不定式完成进行体”。
例如: She said that by the end of May she would have been studying medicine for three years

二、was/were going to +不定式
用做表示过去将来,也通常带有表示过去将来时间得状语。
例如: He said that he was going to live in the country when he retired.
用做表示的动作或事态,也可以是没有实现的意图。
例如:Last  Sunday we were going to go for a picnic but it rained .

三、was/were to +不定式
用做表示过去将来,通常指按过去的计划安排将在某个过去将来时间发生得事态。
例如:They  were not to get away with it if they continued to violate the law.
用作表示过去将来的安排,如果这个安排后来被取消了,没有实现,则用“was/were to +不定式完成体”表示,并可与表示现在、过去或将来得时间状语连用。 此外,其也可用作于表示以后不可避免得要发生得事件。
例如:They said goodbye,little knowing they were never to meet again.

四、was/were about to +不定式
用半助动词be about to 的过去时形式也可使其表示过去将来。这种结构通常指最近的过去将来事态,而且在一定语境中通常指未曾实现的意图:
例如:We were about to start when it began to rain .

五、某些动词的过去进行时可表示过去将来时
come,go,leave,arrive,start等严格按照时间表发生的表起止的动词可用过去进行时代替过去将来时。
例1:He said the train was leaving at six the next morning.他说火车第二天早晨出发。
例2:She told me she was coming to see me.她告诉我她要来看我。

六、特定场合的一般过去时可表示过去将来时
条件状语从句和时间状语从句中须用一般过去时代替过去将来时。
例1:I didn't know when she would come, but when she came I would let you know.我不知道她什么时候来,但她来了我会告诉你。
析:第一个when引导宾语从句,可使用将来时,第二个when引导时间状语从句,只能用一般过去时代替过去将来时。
例2:I didn't know if she would come,but if she came I would let you know.我不知道她是否来,但如果她来我会告诉你。
析:第一个if引导宾语从句,可使用将来时,第二个if引导条件状语从句,只能用一般过去时代替过去将来时。


宾语从句:
在句子中起宾语作用的从句叫做宾语从句。
宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。
宾语从句连接代词主要有:
who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever 等。

宾语从句的特点:
1.宾语从句可以作及物动词、介词及形容词的宾语。
2.宾语从句的语序一律用陈述句语序。
3.连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。
4.whether 和 if 都可引导宾语从句,但 whether后可紧跟or not;whether从句可作介词的宾语。
5.如果从句太长,可以用形式宾语it.

宾语从句的时态:
1.主句是一般现在时,从句根据实际情况使用任何时态。
例句:The headmaster hopes everything goes well.
2.主句是过去时态,从句须用过去时态的某种形式。
例句:She was sorry that she hadn’t finished her work on time.
3.当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。
例句:The teacher told his class that light travels faster than sound.
4. 如果从句的动作发生在主句之前,则从句要用过去完成时态。 

宾语从句的语序:
A. 宾语从句必须用陈述语序。   
False: He is wondering when can he finish this difficult job.   
Right: He is wondering when he can finish this difficult job.
B. 有时候可以用it 作形式宾语,而把真正的宾语从句放在后面。    
Bad: I thought that he could finish this job in just two hours impossible.   
Good: I thought it impossible that he could finish this job in just two hours.  
C. 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.   
Good: I don’t think he likes the English teacher. 
D.  主句一般过去时态,从句也要用过去时态。
False: He wanted to know why he is crying in the corner.   
Right: He wanted to know why he was crying in the corner

宾语从句的否定转移:
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。
并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课,是不是?


宾语从句中引导词的用法比较
在复合句中作主句的宾语,引导词有:
连词:that (that 常可省略),whether, if
代词:who, whose, what ,which
副词:when ,where, how, why 等。

(一)that引导的宾语从句(在非正式场合that可以省略)
1.可跟that从句做宾语的动词有:
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句:The boy believes that he will travel through space to other planets.
注意事项:当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。
例句:I don’t think it is right for him to treat you like that.

2.在以下情况中that不能省略
a.当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省。
例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.
b.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省。
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
c.当that从句是双宾语中的直接宾语时,that不可省。
例句:I can’t tell him that his mother died.
d.注:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语。
例句:I find it necessary that we should do the homework on time.

(二)由whether,if 引导的宾语从句
1.由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。
一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的。
例句:I wonder whether(if) they will come to our party.

2.只能用whether,不能用if引导的宾语从句
a.在带to的不定式前
例句:We decided whether to walk there.
b.在介词的后面
例句:I’m thinking of whether we should go to see the film.
c.在动词后面的宾语从句时
例句:We discussed whether we had a sports meeting next week
d.直接与or not连用时
例句:I can’t say whether or not thet can come on time.

3.只能用if不能用whether引导的宾语从句
a.if引导条件状语从句,意为“如果”
例句:The students will go on a picnic if it is sunny.
b.if引导否定概念的宾语从句时
例句:He asked if I didn’t come to school yesterday.
c.引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about it.

if,whether在宾语从句中的区别
a.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
b.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether. 
c. whether后可以加or not,但是if不可以.
d.在不定式前只能用whether.
(如:I can’t decide whether to stay. 我不能决定是否留下。)
e.避免歧异时,我们常用whether而不用if.

(三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序。
用于这种结构的动词常常是:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
1.英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。
例句:Can you tell me whom you are waiting for?
2.英语中的连接副词有:when,where,why,how,在句中担任状语的成分。
例句:None of us knows where these new parts can be bought.


简化宾语从句常用六法:
方法一:
当主句谓语动词是hope, decide, wish, choose, agree, promise等,
且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。
例如:
Li Ming hopes he will be back very soon.
→Li Ming hopes to be back very soon.
We decided that we would help him.
→We decided to help him.

方法二:当主句谓语动词是know, learn, remember, forget, tell等动词,
且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
She has forgotten how she can open the window.
→She has forgotten how to open the window.
注:当主句谓语动词是tell, ask, show, teach等动词,
且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
Could you tell me how I can get to the station?
→Could you tell me how to get to the station?

方法三:当主句的谓语动词是order(命令),require(需要)等时,
如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。例如:
The headmaster ordered that we should start at once.
→ The headmaster ordered us to start at once.

方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。例如:
He insisted that he should go with us.
→He insisted on going with us.
The poor boy doesn’t know when and where he was born.
→The poor boy doesn’t know the time and the place of his birth.

方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。例如:
Liu Ping found that there was a wallet lying on the ground.
→ Liu Ping found a wallet lying on the ground.

方法六:动词seem后的宾语从句,也可以用不定式(短语)来简化,但句型需要进行适当的变化。例如:
It seemed that the boys were going to win.
→The boys seemed to win.
除上述方法外,还有一些特殊句式的转化。例如:
I found that it was difficult to learn English well.
→I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow.
→Soon we found the ground covered with thick snow.
They found that the box was very heavy.
→They found the box very heavy
