题目内容
12.The traffic accident______this morning.( )| A. | happens | B. | happend | C. | was happened | D. | will happen |
分析 早晨发生了交通事故.
解答 答案:B.
happen发生,为不及物动词,不能用被动语态;根据时间状语this morning,可知这里表示一个过去的时间,所以时态用一般过去时.故选B.
点评 一般过去时表示过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为;过去主语所具备的能力和性格.基本结构:主语+谓语(动词过去式)+句子其他成分;主语+was/were+形容词/名词/介词短语+过去时间;否定形式①was/were+not;②在行为动词前加didn't,同时还原行为动词;一般疑问句Did+主语+do+其他.
