句型转换,求分析
解题思路: 如下
解题过程:
By whom invented
同学:你的原题中invited应为 invented ,对吗?
以下是被动语态的知识,希望对你有所帮助!
被动语态语法讲解
一、 被动语态的用法:
主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者
1. 一般现在时的被动语态:is / am / are + 及物动词的过去分词Our classroom is cleaned everyday.
2. 一般过去时的被动语态:was / were + 及物动词的过去分词A new shop was built last year.
3. 现在完成时的被动语态:has / have + been + 及物动词的过去分词This book has been translated into many languages.
4. 过去完成时的被动语态: had been +及物动词的过去分词 The dish had been eaten up when I got there.
5. 一般将来时的被动语态:will+ be + 及物动词的过去分词A new hospital will be built in our city.
6. 含有情态动词的被动语态:情态动词+ be + 及物动词的过去分词Young trees must be watered often.
7. 现在进行时的被动语态: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.
8. 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、 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.
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.
2. 有些动词用主动形式表示被动意义。This pen writes well. His novel sells well.他的小说畅销。
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
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.
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.
注意:
一.以下不及物动词或动词短语无被动语态:
appear, die ,disappear, end, fail, happen, last, lie, remain, break out, come true, fall asleep, take place.比较: rise, fall, happen是不及物动词;raise, seat是及物动词。
 (错) The price has been risen. (对) The price has risen.
 (错) The price has raised.          (对) The price has been raised.
二、 不能用于被动语态的及物动词或动词短语:
fit, marry, own, wish, cost,agree with, arrive at / in, succeed in, happen to, take part in, belong to
三、 系动词无被动语态:
appear, be, become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn
1) It sounds good. 2)The steel feels cold 3) The method proved (to be ) effective.
四、 带同源宾语的及物动词(dream, live, life),反身代词(oneself),相互代词(each other),不能用于被动语态:
 She dreamed a bad dream last night. He lives a p
五、当宾语是不定式时,很少用于被动语态。
   (对) She likes to swim. (错) To swim is liked by her.
六、“be+过去分词”并不一定都是被动语态,有时是系表结构。
当“be+过去分词”表示动作时为被动语态,be是助动词,be后面的过去分词是主要动词,动作的对象是主语;
当“be +过去分词”表示主语所处的状态时为系表结构,be是连系动词。be后面的过去分词是表语,相当于形容词。
其区分办法如下:
1.如果强调动作或句中有介词by引导出动作的执行者,该句一般为被动语态,否则为系表结构。例如:
The glass is broken. 玻璃杯碎了。(系表结构)
The glass was broken by the boy.玻璃杯被那男孩打碎了。(被动语态)
2.如果句中有地点、频率或时间状语时,一般为被动语态。如:
The magazine is published in Shanghai.这家杂志出版于上海。(被动语态)
The door is locked. 门锁着。(系表结构)
The door has already/just been locked.门已经/刚刚被锁上。(被动语态)
The shop is opened.这家商店开门了。(系表结构)
The shop is opened at 8 a.m. everyday.这家商店每天上午八点开门。(被动语态
七、用某些不及物动词表示被动意义,如carry,cut,drive,iron,keep,lock,open,pick,read,sell,shut,tear,wash,wear,write等等。这类动词既能作及物动词,也能作不及物动词。作不及物动词时,形式上虽为主动,却表示被动意义。例如:
Meat cuts easily.肉容易切。
The car drove easily.这车很容易开。
Your pen writes quite smoothly.你的笔写起来很滑。
八、某些感觉动词的主动态表示被动意义。例如:
This shirt feels much softer than that one.这件衬衫比那件衬衫摸起来柔软得多
That book smells old.那本书有一股霉味。
These oranges taste nice.这些橙子味道很好。
