被动语态的 be,什么时候用 is,什么时候用was书上讲被动语态,有的地方用 is,有的地方用 was.这个怎么用.下面两个例句都来自书上：Teachers are needed everywhere in chinaThe bowl was broken by Allen第二个问题：书上把：The bowl is broken 翻译成：这只碗是破的.为什么不是被打破,上面翻译成被打破的是 was broken,“被”必须是 was
不是、was表示过去被、是以前的动作、而is的话、是一般现在时的、The bowl was broken by Allen这只碗是被allen打破的（过去的动作 过去式） The bowl is broken broken 这里做形容词、意思为 破的
当表示一般现在时态时，用is，而当时态是一般过去时态时，用was。英语中“那只碗被打破了”在翻译成汉语时，习惯用主动语态“这只碗是破的。这里的was不能改为is，因为打破碗的这一动作发生在过去，故用was。
动作发生在过去的就用过去式was、were，发生在现在的就用一般现在时is、are；be动词加动词过去分词都表被动翻译为“被…”亦可灵活省略。你的例子注意第一个是被动句(碗是过去被打破的)，第二个是系表结构不是被动，此时broken为形容词
“为什么不是被打破，上面翻译成被打破的是 was broken，“被”必须是 was 吗"这里用was是指碗已经被打破了，已经是过去的事了，而且这个动作是短暂的， 还有“The bowl is broken
翻译成：这只碗是破的。”这里的is则是指物体带有……的性质，即这碗是破的。清楚吗？ 有的用is，有的用was，和它本身句子的时态是相联系的。Teachers初三中考复习 二 语法知识部分 (二)被动语态-英语-学科复习-中考复习-腾龙远程教育网

(二)被动语态(The passive Voice)
　　一、被动语态(Te Passive Voice)：语态是英语动词的一种形式，用来说明主语和谓语之间的关系，即主动语态和被动语态。主动语态是动作的执行者做主语，被动语态是动作的承受者做主语。只有及物动词才有被动语态。例如：
　　The boys like football.男孩儿喜欢足球。(主动语态)
　　Football is liked by the boys.足球被男孩儿喜欢。(被动语态)
　　二、被动语态的构成：被动语态的构成形式是be+及物动词的过去分词(P.P)，其中动词be是助动词，有人称和数的变化，其变化规则与其作连系动词时完全一样。被动语态的否定句是在第一个助动词后加not，一般疑问句是把第一个助动词提前放到句首。主要时态的被动语态的结构和肯定句、否定句及一般疑问句总结如下：
　　*一般现在时：am/is/are+P.P
　　　　　　　　 Our classroom is cleaned every day.
　　　　　　　　 Our classroom is not cleaned every day.
　　　　　　　　 Is our classroom cleaned every day?Yes,it is.No,it isn't.
　　*一般过去时：was/were+P.P
　　　　　　　　 Our classroom was cleaned yesterday.
　　　　　　　　 Our classroom wasn't cleaned yesterday.
　　　　　　　　 Was our classroom cleaned yesterday?Yes,it was.No,it wasn't.
　　*一般将来时：will+be+P.P
　　　　　　　　 Our classroom will be cleaned tomorrow.
　　　　　　　　 Our classroom won't be cleaned tomorrow.
　　　　　　　　 Will our classroom be cleaned tomorrow?Yes,it will.No,it won't.
　　*现在完成时：have/has+been+P.P
　　　　　　　　 Our classroom has been cleaned.
　　　　　　　　 Our classroom hasn't been cleaned.
　　　　　　　　 Has our classroom been cleaned?Yes,it has.No,it hasn't.
　　*现在进行时：am/is/are+being+P.P
　　　　　　　　 Our classroom is being cleaned now.
　　　　　　　　 Our classroom isn't being cleaned now.
　　　　　　　　 Is our classroom being cleaned now?Yes,it is.No,it isn't.
　　*情态动词：can/must/may/should+be+P.P
　　　　　　　 Our classroom must be cleaned well.
　　　　　　　 Our classroom mustn't be cleaned well.
　　　　　　　 Must our classroom be cleaned well?
　　　　　　　 Yes,it must.No,it needen't.(must提问，否定回答用neen't.)
　　三、被动语态的用法
　　1.不知道动作的执行者是谁。例如：Knives are used for cutting things.
　　2.没有必要指出动作的执行者。This desk is made of wood.
　　3.强调动作的承受者。English is spoken by many people.
　　四、主动语态变成被动语态的方法：
　　1.把主动语态的宾语变成被动语态的主语。
　　2.把主动结构的谓语动词变为被动结构。
　　3.把主动结构的主语变为介词by的宾语。(在含义明确时，by短语可以省略。)例如：
　　Students should speak English in and out of class.
　　 (主语)　　　　　　　　(宾语)
　　English should be spoken in and out of class by students.
　　(主语)　　　　　　　　　　　　　　　　　　　　 (介词宾语)
　　五、需要注意的几个问题。
　　(一)用不带“to”的不定式作宾语补足语的句子，变被动语态时，不定式符号“to”不能省略。
　　例如：
　　1.The boss made the workers work 14 hours a day.
　　　The workers were made to work 14 hours a day.
　　2.He saw the teacher go into the office just now.
　　　The teacher was seen to go into the office just now.
　　(二)相当于及物动词的短语动词，在变为被动语态时，不可丢掉词组末尾的介词或副词。
　　例如：
　　1.The babies must be taken good care of.
　　2.The books mustn't be taken away from the reading.
　　(三)含有双宾语(直接宾语和间接宾语)的句子，变被动语态时，将其中的一个宾语变为主语，另一个不动。(一般是将间接宾语变为被动结构的主语。)例如：
　　My mother gave me a present for my birthday.
　　I was given a present for my birthday by my mother.
　　A present was given to me for my birthday by my mother.
　　六、被动语态常见句型
　　1.be made of 由…构成 (发生物理变化) This desk is made of wood.
　　　be made from 由…构成 (发生化学变化) This kind of paper is made from wood.
　　　be made in 在…生产或制造 The TV set is made in Japan.
　　　be made by 被…制造 These machines are made by the workers.
　　2.be used for 被用于… The key is used for locking the door.
　　　be used to do 被用于做某事
　　　Man-made satellites are used to send and reveive massages.
　　　be used as 被作为…来使用
　　　English is used as a foreign language in many countries.
　　3.be covered with 被…覆盖 The ground was covered with snow after it snowed.
　　4.be filled with 被…装满 The bottle was filled with water.
　　5.It is said that… 据说…
　　　It is said that the population of the world was very small long long

改被动语态1、Someone caught the boy smoking a cigarette .改：The boy was caught smoking a cigarette by someone .（caught 后面加不加to ）2、People don not grow rice in the west of Japan .改：Rice is not grown by people in the west of Japan .3、What does the teacher often tell the boys to do 改：What are the boys often told to do by the teacher 4、Someone saw a stranger walk into the building .改：A stranger was seen to walk into the building by someone .5、It is said that the boy had passed the national exam .改：It is said that the national exam has been passed by the boy .那第一题到底加不加to 如果加to，后面的smoking要不要发生变化？
对的补充：第一题不用加to 因为强调 被抓到时正在吸烟,所以原句要用现在分词smoking做宾语the boy 的补足语,变成被动语态时只需把原句的宾语变为被动语态的主语,谓语改为被动形式,其他成分一般不需要怎么变化的.再如：He was heard singing in the next room.Tom was caught cheating in the exam.(考试作弊被当场抓住)
1.正确,因为是抓到"正在吸烟"2.by people还是省略把，这样比较好3.正确4.最好去掉by someone，不太舒服，虽然没有错5.正确整体来说做得不错，继续努力belong to 加现在分词要怎么使用?Put everything___to you in your bag A:belongs B:bilonged C:bilonging D to belong 标准答案是C 但是老师说过belong不能作被动,不能跟过去分词和进行时.解释是belonging属于现在分词_百度作业帮
belong to 加现在分词要怎么使用?Put everything___to you in your bag A:belongs B:bilonged C:bilonging D to belong 标准答案是C 但是老师说过belong不能作被动,不能跟过去分词和进行时.解释是belonging属于现在分词
belong to 加现在分词要怎么使用?Put everything___to you in your bag A:belongs B:bilonged C:bilonging D to belong 标准答案是C 但是老师说过belong不能作被动,不能跟过去分词和进行时.解释是belonging属于现在分词可以使用.还有怎么判断这里的belonging是属于现在分词还是进行时的?
这个很明显是belong to 的某种形式做everything 的后置定语,那么只能用过去分词（表被动）和现在分词（表主动）Put everything_C:bilonging __to you in your bag这里就是现在分词在做语法填空时,什么时候填非谓语动词的过去分词,什么时候填有be动词的被动式?比如说：The exam ,which was originally to be held in our classroom_______(change)to be the library at the library at the last minute becaus_百度作业帮
在做语法填空时,什么时候填非谓语动词的过去分词,什么时候填有be动词的被动式?比如说：The exam ,which was originally to be held in our classroom_______(change)to be the library at the library at the last minute becaus
在做语法填空时,什么时候填非谓语动词的过去分词,什么时候填有be动词的被动式?比如说：The exam ,which was originally to be held in our classroom_______(change)to be the library at the library at the last minute because of some unknown resons.答案是was changed而我填的是changed我时常犯这样的错误,看语境的话,应该怎么看?
答：你首先要分清谓语动词和非谓语动词.过去分词是非谓语动词,而be+过去分词是谓语动词.就本题而言,首先你要能将which was originally to be held in our classroom 无视掉,能判断出空格处要填的是谓语动词,而不是非谓语动词.你的题干有误,classroom后本应有个逗号的,有了这个逗号,则很容易判断,空格处是谓语动词.如果没有,则容易误以为是过去分词作后置定语.可能是出题者是故意的,其实是不对的.后面应为：to be held .,reasons2011高考语法填空分类练习1.The exam,which was originally to be held in our classroom,____(change) to the library at the last minute.(广州二模) 通过网络搜索,发现是你自己没有注意到这个逗号.另外后面的好象也有改编.评：这模拟题经常出得不好.本题句也有不妥：the exam was changed to the library.就有语病!Change A (in) to B是将A变成B.而出题的句意,显然是：考试改在图书馆进行!这是题外话.另外你还要考虑,-ed动词也有可能是过去式,也是谓语动词.本题如果用changed,只能认为是过去式.The exam changed to the library.和The exam was changed to the library.一样,都 是有语病的句子.只不过出题者的思维就是：那场本该在教室举行的考试在最后一刻（被）改到图书馆了.
fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffafffffffffffffffffffffffffffeeee
如果用被动式一般是谓语成分；而过去分词是表示状态，过去完成的动作对现在还有影响。
classroom后面应该有逗号吧？
要看这个动词在句子中的成分，如果是做谓语动词，就要用be+-ed,如果做定语，就不要用be动词
主要是看主语，这里的主语是“考试”，考试是人为安排的，所以动词要用被动，表示的意思就是“考试被改变了，地点在图书馆”
The exam was changed.
看句子主语和动词之间的关系，是主动关系还是被动关系，像这个句子，主语是the exam,和change的关系是被动关系就用was changed
