现在完成时考频图 * 1 主讲人：谢嘉丽 现在完成时 The Present Perfect Tense 总结上海2015年十几个区的中考一模试卷语法部分之后，主要考查的时态有完成时、将来时、进行时、过去时和一般现在时。在考查到的这5种时态中，完成时占了很大的比例，也就是说每张卷子的2~4道时态题中至少都有一道题是考查完成时，完成时的基本结构是have/has+done（过去分词），常用的完成时分成三小类：现在完成时、现在完成进行时和过去完成时，整理上海2015年十几个区的中考一模试卷，发现一共有9个区的一模考查了现在完成时，2个区考查了过去完成时，没有涉及到现在完成进行时，所以在这里我主要强调说明各区语法题的宠儿----现在完成时 如何识别现在完成时 解题技巧和步骤 总结和练习 学习思路 现在完成时的结构 肯定句：主语 +have/has +过去分词 e.g. I have not crossed some sort of line. 否定句：主语+have/has+not+过去分词 e.g. I have crossed some sort of line. 如何识别现在完成时 1.现在完成时用来表示从过去一直持续到现在的动作或状态。 Eg: Mary _D_ in mat housing estate since she came back to Shanghai in 2005. (松江一模) A. is living B. had lived C. would lived D. has lived 2.现在完成时不仅表示动作在说话之前已经完成，而且强调对现在的影响和联系，动作本身对现在造成一定影响。也就是说动作或状态发生在过去但他的影响现在还存在。 Eg：：Our monitor __C__ to bring the key, so we can’t enter the classroom right now. (虹口一模) A. forgets B. forgot C. has forgot D. had forgot (含义是：刚刚我们进不了门) Michael has been ill. （含义是：现在仍然很虚弱） He has returned from abroad. （含义是：现在已在此地） 如何判断现在完成时 1.找标志词 2.联系上下文语境，看过去发生的事情是否对现在造成影响 Eg：：Our monitor __C__ to bring the key, so we can’t enter the classroom right now. (虹口一模) A. forgets B. forgot C. has forgot D. had forgot already , yet , just, before, so far, in the past few years, since +时间点, for +时间段 Eg：- Am I late? （普陀一模） - Don’t worry. Your favourite broadcast __D__ yet. A. doesn’t start B. didn’t start C. won’t start D. hasn’t started 3.现在完成时用来表示从过去一直持续到现在的动作或状态。 Eg: Mary _D_ in mat housing estate since she came back to Shanghai in 2005. (松江一模) A. is living B. had lived C. would lived D. has lived 与一般过去时的区别 一般过去时：有表示过去时间点的提示词 eg: Starbucks(星巴克)__B__ as a small coffee shop in a market in Seattle in 1971. (虹口一模) A. start B. started C. has started D. had started 本题中有明显的过去时间状语in 1971，所以用过去时，做题需要看清楚题目时间范畴。 现在完成时：有already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等提示词 Eg: -Have you ever
