    40、 或具体的时间连用,有时句中会有感官动词来提示,或通过上下文来暗示。21 教育网表示现阶段一直进行的动作。这类动词常常是延续性动词。常于 at present, this week, these days等连用。21cnjycom表示主语的特征、性格、能力等。现在完成时(1)含义:表示过去发生的动作对现在还有影响。(2)基本结构:主语 + have / has + 过去分词(3)基本用法:表示过去发生的动作,但强调对现在产生影响。特征:不能与表示具体的时间状语连用。表示过去发生的动作或存在的状态一直延续到现在,还可能继续下去。常常与 since, for, in the past + 时间名词

    41、,in the last +时间名词等时间状语连用,而且谓语动词要求是延续性动词。表示一种“经历或体验”,即可以表示经历过也可以是从来都没有经历过。被动语态初中阶段我们学习了七种被动结构,归纳如下:(1)一般现在时是被动语态:am / is / are + 过去分词(2)现在完成时的被动式: have / has + been + 过去分词(3)现在进行时的被动式:am/ is/ are + being + 过去分词(4)一般过去时的被动式:was / were + 过去分词(5)过去进行时的被动式:was / were + being + 过去分词(6)过去完成时的被动式:had + bee

    43、didnt use。在英式英语中,它的疑问式应当是:Used 主语 to sth?否定式应当是 used not to 或 use(d)nt to 。He used to stay up late. 他过去常熬到很晚。【实战演练】I. 用所给词的适当形式填空。1. The old man used _ (be) a teacher. 2.
