一般现在时的被动语态
在英语中，动词有两种语态，即主动语态和被动语态。被动语态的基本结构是“助动词 be + 及物动词的过去分词”，其中助动词be有人称、数和时态的变化,其变化规则与be作为连系动 完全一样。
1.一般现在时被动语态的各种句式结构
肯定式 主语+am/is/are+过去分词（ + by…)
否定式 主语+am/is/are + not +过去分词 (+by…)
疑问式 Am/Is/Are+主语+过去分词(+ by …)
特殊疑问词+ am/is/are+主语+过去分词（+ by ...)
助记：
被动不离“be” “p.p.”, “p.p.”前面助动be。
主谓一致莫忘记，am, is, are现在时。
2.一般现在时被动语态的基本用法
用法 示例
表示经常性或习惯性发生的被动动作 I am often asked the question by my pupils.
表示近期正在发生的被动动作 These days people are moved by a teacher named Zhang Lili.
描述某种常态化的被动的客观事实 The spaceship is mainly controlled by computer.
强调目前存在的针对行为主体人的被 限制性动作
You aren’t allowed to take photos.
3.主动语态变为被动语态的方法
第一步:将主动语态的宾语改为被动语态的主语；
第二步:将主动语态的谓语改为“be+及物动词的过去
分词”结构；
第三步:将主动语态的主语改为介词by的宾语，放在
谓语之后(有时可省略)。
如图示：
They (主语）grow (谓语）tea (宾语）in the south-east of China.
被动语态:
主动语态:
Tea (主语）is grown (谓语）by them in the south-east of China.
含有情态动词的被动语态
句式 结构 示例
肯定句 主语+情态动词+be+及物动词的过去分词(+by…) Teenagers should be allowed to go shopping.
否定句 主语+情态动词+not+be+及物动词的过去分词(+by…) The word can’t be used in this sentence.
一般疑问句 情态动词+主语+be+及物动词的过去分词(+by…) Must the work be finished today
特殊疑问句 特殊疑问词+被动语态的一般疑问句？ Who should be asked for help

chance (a suitable time or situation when you have the opportunity to do sth.) 可数名词，意为“机会；机遇”，其后可接to do sth.或of sth.。若表示“做某事对某人来说是一次机会”，其后可接for sb. to do sth.。

manage to do sth. 与 try to do sth.

to clean it.
