48、特征、性格、能力等。2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：用。表示过去发生的动作或存在的状态一直延续到现在，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还可能继续下去。常常与 since，for, in the past+时间名词，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”，既可以表示经历过也可以是从来都没有经历过。3被动语态 初中阶段我们学习了八种被动结构，归纳如下：(1)一般现在时的被动式：(2)现在完成时的被动
