| A. | was; was raining | B. | is; has rained | ||
| C. | is; is raining | D. | will be; will rain |
分析 ---事故是怎样发生的?
---你知道,因为在下雨很难看清路.
解答 答案:A.结合How did the accident happen可知表达的是过去的事情,故用一般过去时,结合it ________difficult to see the road clearly 用it was+adj+to do sth做某事是怎样的,后文是表达过去正在进行的动作,故用过去进行时was/were+doing,故答案是A.
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.
