It had been raining cats and dogs for over a week and the downpour had caused landslides in many places.
(3)将来完成进行时表示在将来某一时刻之前开始的一个动作或状态一直延续到将来某一时刻。例如：
By the time you arrive tonight, she will have been typing for hours.
四：时态一致
时态一致是英语四、六级考试的一个重要内容。通常应由主句谓语的时态决定从句的谓语时态。一般原则是：
1、当主句谓语使用现在时或将来时，从句的谓语根据具体情况使用任何时态
He says that he lives in Wuhan.
We hope that there will be many people at your party today.
“Did you hear that Bill finally sold the house?” “Yes, but I don’t know who bought it.”
“There’s a lot of excitement on the street.”
“There certainly is. Do you suppose the astronauts have returned?”
2、当主句谓语使用过去时的时候，从句的谓语必须使用过去范围的时态
He said he was writing a novel.
The teacher wanted to know when we would finish the experiment.
He said his father had been an engineer.
3、当从句是表示没有时间概念的真理时，从句的谓语应使用一般现在时。例如：
The teacher told them since light travels faster than sound, lightning appears to go before thunder.
注：在此种情况下，即使主句谓语用了过去式的各种时态，从句谓语也应用一般现在时。
4、从句谓语只能用虚拟语气的情况
利用时态一致原则确定从句动词时态时，还应注意，若主语动词是表示命令、请求、要求、建议、劝告等的动词，从句谓语只能用虚拟语气，不能遵循时态一致原则。例如：
We insisted that we do it ourselves.
动词的语态
语态也是动词的一种形式，英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态表示主语是动作的承受者。
1)We use electricity to run machines. (主动语态)
2)Electricity is used to run machines. (被动语态)
1.不能用于被动语态的动词和短语
(1)在英语中，不及物动词不能用于被动语态，但有些不及物动词(包括短语)容易引起误用。如：appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。
(2)某些表示状态或特征的及物动词，如：become, contain, cost, fit, have, resemble, suit也没有被动语态。
2.被动语态的时态形式
常用的被动语态有表1所列的几种时态形式。
表1
时?SPAN lang=EN-US> 一般时 进行时 完成时
现在 am asked am being asked
is asked is being asked
are asked are being asked
过去
was be asked was being asked
were be asked were being asked
将来 shall be asked shall have been asked
will be asked will have been asked
过去 should be asked should have been asked
将来 would be asked would have been asked
3.短语动词的被动语态
短语动词转换为被动语态时，通常被看作是一个动词，后面的介词或副词不能拆开或省略。例如：
1)So far no correct conclusion has arrived at.
2)All the rubbish should be got rid of.
4.“get + -ed分词”的被动语态
“get + -ed分词”结构强调动作的结果，而非动作本身，常用来表示突发性的，出乎意料的偶然事件。例如：
The boy got hurt on his way home from work.
另外，“get + -ed分词”还可用于谈论为自己做的事，是主动的行为而不是被动的行为。例如：
get dressed(穿衣服) get divorced(离婚)
get engaged(订婚) get confused(迷惑不解)
get lost(迷路) get washed(洗脸)
get married(结婚)
5.能带两个宾语和复合宾语的动词改为被动语态
(1)能带两个宾语的动词改为被动语态时，一次只能由一个宾语作主语，另一个宾语被保留下来。例如：
1)We showed the visitors our new products.(主动语态)
2)The visitors were shown our new products.(被动语态)
3)Our new products were shown to the visitors.(被动语态)
(2)能带复合宾语的动词改为被动语态时，原来的宾语补足语变为主语补足语。例如：
1)The teacher appointed him League secretary.(主动语态)
2)He was appointed League secretary.(被动语态)
6.被动语态与系表结构的区别
(1)The novel was well written.(系表结构)
(2)The novel was written by Diskens.(被动语态)
7.少数动词的主动语态有时有被动的意思
例1：The book is selling remarkably well.
例2：The song sounds very beautiful.
能这样用的动词还有read(读起来)，clean(擦起来)，wash(洗起来)，write(写起来)。
例3：My watch needs cleaning. (= My watch needs to be cleaned).
能像need这样用的动词还有：want, require, deserve, do, owe, bind等。
例4：The meat is cooking.
例5：The book written by the professor is printing.
在英语中被动语态分时态,我给你举些例子:
(1)一般现在时:This song is often sung by children.孩子们常唱这首歌.
(2)一般过去时:This house was built in 1958.这房子建于1958年.
(3)一般将来时:Many buildings will be built in my home town.在我的家乡,许多大楼将要建成.
(4)过去将来时:The old scientist said that he would be invited to vist their country before long.那位老科学家说不久他将应邀访问他们的国家.
(5)现在进行时:The proposal is being considered now.正在考虑这个提案.
(6)过去进行时:Mr Wu was in hospital .When we went to see him,he was being operated on.吴先生住院了.我们去看他时,他正在动手术.
(7)现在完成时:Have the letters been posted ?信已经寄出去了吗?
(8)过去完成时:He came and told us that the work had been finished.他来告诉我们,工作已经完成.
(9)将来完成时:By the end of this year,the tall building will have been built.到今年年底,这幢高楼将建成.
(10)过去将来时:The boy told mother that his homework have been finished by ten o'clock.男孩告诉妈妈到10:00他将做完作业.
动词的语态
语态有两种：主动语态和被动语态.
主语是动作的发出者为主动语态；主语是动作的接受者为被动语态.
1）若宾语补足语是不带to 的不定式,变为被动语态 时,该不定式前要
加"to".此类动词为感官动词.
feel, hear, help, listen to, look at, make, observe, see, notice, watch
The teacher made me go out of the classroom.
--> I was made to go out of the classroom (by the teacher).
We saw him play football on the playground.
--> He was seen to play football on the playground.
2）情态动词+ be +过去分词,构成被动语态.
Coal can be used to produce electricity for agriculture and industry.
1 let 的用法
1）当let后只有一个单音节动词,变被动语态时,可用不锋誉带to 的不定式.
They let the strange go.---> The strange was let go.
2） 若let 后宾补较长时,let 通常不用被动语态,而用allow或permit 代替.
The nurse let me go to see my classmate in the hospital.
----> I was allowed / permitted to see my classmate in the hospital.
2 短语动词的被动语态
短语动词是一个整体,不可丢掉后面的介词或副词.
This is a photo of the power station that has been set up in
my hometown.
My sister will be taken care of by Grandma.
Such a thing has never been heard of before..
3 表示"据说"或团基帆"相信" 的词组

remain, sit, spread, stand

典：done,"不可能已经".must not do 不可以（用于一般现在时).
一、 被动语态的用法：

二、 怎样把主动语态改成被动语态?
把主动语态改为被动语态非常简单,可以遵循以下几个步骤：
1. 先找出谓语动词；
2. 再找出谓语动词后的宾语；
3. 把宾语用作被动语态中的主语；
4. 注意人称、时态和数的变化.
例：1. Bruce writes a letter every week. →A letter is written by Bruce every week.
2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
3. He has written two novels so far.→Two novels have been written by him so far.

三、 使用被动语态应注意的几个问题：
1. 不及物动词无被动语态.
What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
2. 有些动词用主动形式表示被动意义.
This pen writes well.
This new book sells well.
3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带to ,但变为被动语态时,须加上to .
例：make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定.
He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike. →A new bike was bought for me by my father.
5. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词.
We can’t laugh at him. →He can’t be laugh at by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.
你好
英语的语态分为主动语态和被动语态两种，而在英语中习惯誉岩使用被动语态，汉语中以主动语态为主。中主动语态表示主语是动作的发出者或执行者，而被动语态则表示主语是动作的承受者。那么主动语态如何转化成被动语态呢？
一、被动语态的构成
被动语庆汪御态由“be动词+过去分词”构成：如
Everybody likes the cute girl. 大家都喜欢这个可爱的女孩。(主动语态)
The cute girl is liked by everybody. 这个可爱的女孩受到大家的喜欢。(被动语态)
二、主动语态变被动语态的基本方法
将主动语态的宾语变为被动语态的主语，将主动谓语变为被动谓语(be+过去分词)，将主动语态的主语变为by短语(在被动句中用作状语)，如：
He finished the task. → The task was finished by him.
注：如果不强调动词发出者，被动语态中的by短语通常可以省略。
三、 特殊用法
主动句可以转换成两种被动句型，它们通常是一些表示客观说明的句子，如：
People believed that the old man is innocent. 大家相信那个老人是无辜的。
→ It’s believed that the old man is innocent.. 大家相信那个老人是无辜的。
→ The old man is believed to be innocent. 大家相信那个老人是无辜的。
比较上面两类被动句型可以发现，一类是“it+be+过去分词+that从句”，另一类则是“主语+be+过去分词+不定式”，通常可用于这两类被动句型的动词有suppose, think, understand, assume, believe, expect, presume, report, say, fear, feel, know,等，如：
It’s known that she is a kind girl. =She is known to be a kind girl. 大家知道她是个善良的女孩。
It’s expected that he will be better soon. = He is expected to be better soon. 他应该很快就会好起来。
以上就是主动句变被动句的方法。其实，主被动在我们写作或翻译过程中还是非常重要的，英语多被动，汉语多主动，所以学会这两种语态的转变对我们今后的学习至关重要。所以，希望大家能多思考对比，反复练习运用，尽快掌陵租握该知识点。
