几种常见时态的相互转换
英语中的几种时态在一定情况下可以互相转换，以下是几种常见的转换形式：
一、 一般过去时与现在完成时的转换
在现在完成时中，延续性动词能与表示一段时间的状语连用，瞬间动词却不能。但是，可用别的表达方式：①瞬间动词用于“一段时间 + ago”的一般过去时的句型中；②瞬间动词可改成与之相对应的延续性动词及短语，与一段时间连用；③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中，表示“自从……以来有……时间”的意思，主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看：
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、 一般现在时与现在进行时的转换
在一般现在时中，at加上名词表示“处于某种状态”，如at work（在工作）, at school（上学、上课）等。此短语可与进行时态转换。请看：
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、 现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如：I am coming, Mum! 意为“我就来，妈妈！”请看：
The train is leaving soon.
The train will leave soon.
四、“be going to+动词原形”与“will+动词原形”结构的转换
“be going to+动词原形”、表示打算、计划要做的事；将来时“will+动词原形”结构在书面语中，当主语为第一人称时，常用助动词shall。在口语中，所有人称都可以用will。请看：
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday.
英语句子被动问题
这里是两种主动表示被动。第一个不定式的主动表被动，遇到表示主语的性质，本性的词，如hard,easy,difficult,comfortable 等词时，主动表示被动。如The chair is comforable to sit in.
The problem is difficult to solve. The work is easy to do. The article is hard to understand.等
第二种时谓语动词的主动表示被动，在这里不强调主语被做，而是强调主语的性质，标志性的副词有well,easily,difficultly 等，如The book sells well.，be to rent（出租）也用主动形式表被动
我是辛辛苦苦打出来的，望采纳
高中英语主动表被动的单词和句型有哪些呢？
1.英语中有很多动词如break, catch, clean, drive, lock, open, sell, read，write, wash等, 当它们被用作不及物动词来描述主语特征时，常用其主动形式 表达被动意义,主语通常是物。例:
This kind of cloth washes well.
My pen writes smoothly.
These books sell well.
2. 表示“发生、进行”等的不及物动词和短语, 如: happen, last, take place, break out, come out, come about, come true, run out等以主动形式表示被动意义。
例: How long did it last?
Great changes have taken place in Shanghai in the last few years.
I wish my dream would come true.
3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, smell, look等在主系表结构中常以主动形式表示被动意义。
例:Your reason sounds reasonable.
* 注意区分它们作
行为动词时可以被动:
An air of depression
was felt.
4． 在need，want，require等词的后面, 动名词用主动形式表示被动意义, 其含义相当于动词不定式的被动形式。
例: The house needs repairing.
to be repaired
5. 形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。
例: The book is well
worth reading．
＝The book is well
worthy to be read．）
6. 动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。
例: I have a lot of things to do this afternoon．
试比较：I’ll go to the post office. Do you have a letter to be posted?
7. 在某些“形容词＋不定式”做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice, easy, fit, hard, difficult, important, impossible, pleasant, interesting .例:
•English is easy to be learned.
•English is easy to learn.
•这道题很难解出.
This problem is difficult to work out
8． 在too… to…结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。例:
This book is too expensive to buy.
6. blame仍用不定式的主动形式表示被动意义。
Who is to blame for starting the fire?
The children were not to blame for the accident
高中英语，完成句子第二题，为什么表被动还要加of 呢，谢谢！
因为从所给出的“如果被照顾得很好，这种鸟可以五年这么长时间。”可以知道是用被动，又因为of是“属于……的”这里是说属于被人照顾的鸟可以活很长时间。更多
.请问of是介词吗？
是
谢谢~
英语的主动表被动句型是怎样的？能否举例？
主动变被动和咱们汉语理解起来相差不多，我们只需要注意该主动句中的动词为及物的，那么就可以变被动了，变得时候规则是将主动句的宾语放最前面也就是作新句子的主语，然后加be动词的适当形式（时态及数的变化），再加上主动句谓语动词的被动式（动词的分词形式）。再补上动词的执行者by ...比如说，She sings a rock song at the party.变被动式：A rock song is sang by her at the party.
I took the phone yesterday.被动式：The phone is taken by me yesterday.
希望对你有帮助！
被动句的英语
谓语动词的语态表示句子的主语和谓语动作之间的关系
1）当句子的主语是谓语动作的执行者时，主、谓之间的关系称为主动语态；
2）当句子的主语是谓语动作的承受者时，主、谓之间的关系称为被动语态。例如：
I teach English.主动语态。
Our English is taught by him.被动语态。
在被动语态的句子中，谓语部分的结构是be + p.p.（过去分词）。被动语态的句子有时态的变化，这个变化反映在be动词上。也就是说，把一个句子做成被动语态的句子，只需要写出BE动词的所需时态，再加上所给动词的过去分词就行了。当然，这只是指谓语部分而言。我们知道，be动词作为一个独立的谓语动词有自己现在分词（being）和过去分词 （been）。那么，下面我们来看看be在各种时态中的变化形式：
一般现在时 am / is / are
一般过去时 was / were
一般将来时 shall / will + be
过去将来时 would / should + be
现在进行时 am / is / are + being
过去进行时 was / were + being
现在完成时 have / has + been
过去完成时 had + been
说明：1）以上的八个时态可用于被动式，其它没有列举的时态都不宜用于被动语态的句子中。2）另外，表中被斜线隔开的词表示，供根据具体情况作选择。弄清楚了be在各种时态中的变化形式以后，我们就能很轻松地写出被动语态的各种时态了。我们可看看下面的实例：
English is spoken in many countries all over the world .（一般现在时）
世界上许多国家都讲英文。
Some TV sets for sale in the department store were stolen last night. （一般过去时）
那家商场用来出售的部分电视机昨晚被盗。
He won't be allowed, by his father, to marry lucy. （一般将来时）
他父亲不会让他娶露西为妻的。
They would be sent to the army when they finished the training. （过去将来时）
他们结束训练时将被派往部队。
The project is being carried out.（现在进行时）
这个计划正在执行中。
The case was being investigated then.（过去进行时）
那时这案子正在调查中。
This novel has been translated into several languages. （现在完成时）
这本小说已被译成了几种语言。
They said that production costs had been reduced. （过去完成时）
他们说生产成本已经下降了。
一般来说，在我们日常生活中，能用主动语态的时候就尽量不去用被动语态。
只有在下列情况中我们才用被动语态：
1）不清楚动作的执行者是谁, 例如:
The front window in the classroom was broken yesterday. 昨天，教室的前窗被打破了。
The time-table has been changed .时间表已变动了。
We haven't been informed of it .还没有人通知我们这事儿。
2)说话人对宾语的兴趣大于对主语的兴趣（这时可用by引导出动作的执行者），例如：
My TV set is being repaired in the shop. 我的电视机正在这店里修。
These books are written especially for children. 这些书是专门为孩子们写的。
The song was composed by a young worker. 这首歌是一位年青工人谱写的。
3) 不愿意说出动作的执行者，其目的是为了使语言得体、圆滑等。在这种情况下，有时常用一些句式，如It is said that…（据说……），It is reported that …（据报道……），It is rumoured that …（据传言……）等等。例如：
You are requested to make a speech at next meeting. 请您在下次会议上作个发言。
It is said that she is going to be married to a foreigner. 据说她要嫁给一个外国人。
It is rumored that he has been appointed as successor to the president of our company . 据传闻，他已被任命为我们公司总裁的接班人了。
It is generally considered impolite to ask one's age, salary, marriage, etc.. 问别人的年龄、工资、婚姻状况等通常被认为是不礼貌的。
4) 出于修辞的原因，或是说为了更
The professor came to our school and warmly welcomed by the teachers and students.（句子的后半句用被动式就可以只安排一个主语。）那位教授来到我校并受到师生们的热烈欢迎。
I went to the party and was asked by my friends to do some cooking for them. （同上）我去参加了那个聚会，朋友们还请我为他们烧了几样菜。
The notion is especially opposed to by those who have invested much in the area.
（此句若选those作主语，就会使主语与谓语相距太远而显得句子松散，因为它的定太长了。）这个提议特别遭到了那些在本地区投资很大的人的反对。
这里我们还要进一步谈谈几种特殊的被动结构。
1）关于带情态动词的被动结构
带情态动词的被动结构的固定句式为情态动词 + be + 过去分词。也有个别带to的情态动词例外，如：ought to和have to ，它们的被动结构就只能在不定式中。例如：
The debt must be paid off before next month. 那笔债务必须在下个月前付清。
The debt has to be paid off before next month. 那笔债务必须在下个月前付清。
Oil can be turned into energy by burning it. 油经过燃烧可变为能源。
You ought to be criticized for your carelessness. 你由于粗心大意应当受到批评。
2) 关于带有两个宾语的主动态变成被动态
我们先来看看带有两个宾语的主动态句子的结构，重点看谓语部分 ：
She sent me a novel on my birthday .
主 谓 间接宾语 直接宾语 状语
I allowed him an hour to finish the work .
主 谓 间接宾语 直接宾语 状语
从上面的分析可以看出，两个宾语分别是：直接宾语和间接宾语。将这种主动态的句子变成被动态的句子，可选两个宾语中的任何一个作为被动态句子的主语，而将另一个宾语作为保留宾语写入被动态的句中。但有一点要说明，那就是，如果你选直接宾语作主语，有时要在被动态句子的保留宾语前加上合适的介词。因为这些动词常有两种句式，即：我们可以说give sb sth , send sb sth , buy sb sth ；我们也可以说give sth to sb, send sth to sb , buy sth for sb 。请看下面两种情况的对照：
She sent me a novel on my birthday.
I was sent a novel on my birthday.
A novel was sent to me on my birthday.
My brother bought me a watch yesterday.
I was bought a watch yesterday.
A watch was bought for me by my brother yesterday.
3)关于带有复合宾语的主动态变成被动态
如果将带有复合宾语（既：宾语 + 宾语补足语）的主动态的句子变成被动态的句子，我们只能选择原来句子的宾语作被动态句子的主语；而这时，原句里的宾语补足语就变成被动态句子的主语补足语了。例如：
The story made us laugh .
We were made to laugh by the story.
They asked me to help them.
I was asked to help them.
We saw them coming over.
They were seen coming over.
一、 被动语态的用法：
1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词
Our classroom is cleaned everyday.
I am asked to study hard.
Knives are used for cutting things.
2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词
A new shop was built last year.
Dinosaur eggs were laid long long ago.
3. 现在完成时的被动语态构成：has / have + been + 及物动词的过去分词
This book has been translated into many languages.
Many man-made satellites have been sent up into space by many countries.
4. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词
A new hospital will be built in our city.
Many more trees will be planted next year.
5. 含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词
Young trees must be watered often.
Your mistakes should be corrected right now.
The door may be locked inside.
Your homework can be handed in tomorrow.
6. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词
Uncle Wang is mending my bike now.→
My bike is being repaired by Tom now.
They are planting trees over there. →
Trees are being planted over there by them.
7. 不定式的被动语态：to + be + 及物动词的过去分词
There are two books to be read. →
There are twenty more trees to be planted.
二、 把主动语态改成被动语态的方法
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.
4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
5. Lucy is writing a letter now.→A letter is being written by Lucy now.
6. You must lock the door when you leave.→the door must be locked when you leave.
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 him. →He can’t be laugh 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.
