动词的时态和语态
常考被动语态的构成 一般现在时 am/is/are+done 如:Football is played in most countries in the world.
一般过去时 was/were+done 如:My bike was stolen last night.
一般将来时 will/shall/be going to+be+done 如:The new film will be shown next Thursday.
含情态动词 情态动词+be+done 如:The environment should be improved.
主动语态变被动语态 巧记:宾变主,主变宾,谓语动词用被动。
主动形式表示被动意义 某些动词+副词well, easily, badly, smoothly等,且主语是物 动词包括:read, write, act, cut, wash, clean, draw, sell, lock, cook等 如:The cloth washes easily. This kind of pen sells well here.
其他结构 sth+needs/requires/wants+doing sth 如:The desk needs repairing.
be worth doing sth 如:The book is worth reading.
【注意】
使役动词和感官动词后接不带to的动词不定式作宾语补足语时,变被动语态时要还原to 此类常见词归纳: 一感(feel) 二听(hear/listen to) 三使(make/have/let) 四看(look/see/watch/notice) 如:I heard Amy sing that morning. 那天早上我听到Amy在唱歌。 →Amy was heard to sing that morning. 那天早上Amy被听到在唱歌。
带有双宾语的动词变为被动语态有两种表达方式 此类常见词包括:give, buy, sell, take, bring, make, hand, pass, keep, send等 如:He gave the girl a toy.他给了这个女孩一个玩具。 →The girl was given a toy.这个女孩分到了一个玩具。 →A toy was given to the girl.一个玩具被分给了这个女孩。
动词短语变被动语态时,不要丢掉动词后面的介词或副词 如:Mary looks after the children carefully. Mary很细致地照顾这些孩子。 →The children are looked after by Mary carefully. 这些孩子被Mary细致地照顾着。
