39、动作。特征：常常与now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。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。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，in th

40、e 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 + been + 过去

41、分词（7）一般将来时的被动式：will / be going to be+ 过去分词（8）含有情态动词的被动式：情态动词+be +动词的过去分词。情态动词情态动词表示说话人对某一动作或状态的态度，如认为“可能”、“应当”、“必要”等。情态动词本身有一定的意义，但不能单独作谓语，也没有人称和数的变化。后面一般跟动词原形。used to 结构used to意为“过去常常做某事”，指的是过去的习惯性动作，目的在于与现在形成对照。used to是个情态动词，其中的to是不定式符号，后面跟动词原形。在美式英语中。它的疑问式是：Did 主语use to do sth？否定式是：主语didnt use。在英

42、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. We should _ (clean) the room every day. 3.
