GrammarFocus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...)?疑问式主语+am/is/are+not+过去分词(+by…)
否定式主语+am/is/are+过去分词（+by…)肯定式被动不离“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Youaren’tallowedtot
akephotos.强调目前存在的针对行为主体人的被限制性动作Thespaceshipismainlycontro
lledbycomputer.描述某种常态化的被动的客观事实Thesedayspeoplearemovedby
ateachernamedZhangLili.表示近期正在发生的被动动作Iamoftenaskedthequ
estionbymypupils.表示经常性或习惯性发生的被动动作示例
用法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）intheso
uth-eastofChina.被动语态:主动语态:Tea(主语）isgrown(谓语）bythemint
