语法：时态语态综合初中阶段考查8种时态，分别是一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时和过去将来时。

今天我们涉及6个时态，分别是一般现在时、一般过去时、一般将来时、现在进行时、过去进行时和现在完成时。

英语的语态分为主动语态和被动语态，主动语态表示主语是动作的执行者。

被动语态表示主语是动作的承受者，目前中考主要考查一般现在时、一般过去时、一般将来时和现在完成时这四种时态的被动语态以及含情态动词的被动语态。

只有及物动词才有被动语态。

它的基本结构为：be动词+及物动词的过去分词。

所有的时态变化在be动词上。

动词时态：动词语态注意以下几种被动语态的特殊情况：一．被动语态中不定式要还原Let/make/see/hear/watch sb. do sth.----- sb. be let/made/seen/heard/watched to do sth.My mother made me look after the little sister yesterday.----I was made to look after the little sister by my mother yesterday.二．有些动词没有被动语态。

(及物动词才有被动语态)1) 不及物动词或动词短语无被动语态：appear, die，disappear, end (vi. 结束), fail, happen, last, lie, remain, sit, spread, stand break out, come true, fall asleep, keep silence, lose heart, take place.2) 系动词无被动语态：appear, be，become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn3) 不能用于被动语态的及物动词或动词短语：fit, have, hold, marry, own, wish, cost, notice, watch，agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to4) 系动词无被动语态：appear, be，become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn5) 当宾语是不定式时，很少用于被动语态。
