Answer 1

1.The flowers must be watered every day 2.A dictiomary can be used by you in the exam 3.Can this video be mend by you? 4.Children should not be allowed to work by us at night 5.Their classroom must be cleaned by the students every day 被动语态就是说实话真的是很简单的语法 也许刚学所以你可能不太懂 没关系 把握住三点就可以了 说明【大体框架结构是自己打的 中间例句是找的哦】

1，被动语态的基本形式 sb/sth +be+过去分词 这个形式记住了 剩下的就往里套就可以

例如：
主动：People regard him as brilliant.
被动：He is regarded as brilliant by people.
人们认为他很有才华。

2，时态的把握 如果学过时态 就是相当于在被动语态中使用时态而已 没什么不一样 只不过就是把名词被动化了

一般现在时：be done（be随人称变化）
一般过去时：was/were done
一般将来时：will be done
现在进行时：be being done（前面的be随人称变化，后面的being固定）
过去进行时：was/were being done（being固定）
将来进行时：will be being done（being固定）
现在完成时：have/has been done
过去完成时：had been done
将来完成时：will have been done
将来完成进行时：will have been done
现在完成进行时：have been being done
过去将来时：would be done
过去将来完成时：would have been done
过去完成进行时：had been being done
过去将来进行时：would be being done
过去将来完成进行时：would have been being done

三、千万注意一些词的在被动语态中的用法 常考点哦！
1， 不及物动词无被动语态。
2. 有些动词用主动形式表示被动意义。
This pen writes 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

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 him. →He can’t be laugh by us.

改被动语态就是把某人做了某事，改为某是被某人做了。
