X k b 1. c O m三情景解疑现在完成时1. 构成：has / had + 动词的过去分词2. 基本用法： 表示过去发生或已经完成的动作对现在造成的影响和结果。可以表示最近完成的动作，也可以表示经历或经验。表示过去已经开始、持续到现在（可能还会继续进行下去）的动作或状态，常和表示一段时间的状语连用。3. 时间状语：just, recently, so far, up to now, till now, in the past, ever, never, for, since, these days, this year, now等。4. 短暂性动词和延续性动词： 短暂性动词用于完成时态时，不表示延续概念，不能跟表示一段时间的状语连用，需要时要用相应的延续性动词替换。常见的有：buy have, borrow keep, leave be away, die be dead, return be back, put on wear, catch a cold have a cold, fall asleep be asleep【例】 Since two years ago.A. How long have you joined Greener China?B. How long did you join Greener China?C. When did you join Greener China?D. How long have you been with Greener China? 解析：Since two years ago.表示的是时间段，因此问话问的应该是多长时间，答案在A，B和D之间选。由于动词join是短暂性动词，无延续性，不能与表示一段时间的状语连用，故选D。w w w .x k b 1.c o m四合作探究【思考】读下列例句，说说一般过去时和现在完成时的区别是什么？ The light has gone out.
