现在完成时复习讲义（含答案）2023-2024学年仁爱版英语九年级上册

现在完成时（Present perfect） 一 现在完成时定义： (1) 表示过去发生的动作对现在造成的影响/结果。 例如： I have read the book. （影响可能是我能把书借给你。） I haven't finished my homework.（影响可能是我不能出去玩。） I have just visited the museum.（影响可能是我不去了。） 过去发生的动作或者存在的状态持续到现在。这个动作可能刚停止，可能仍然在进行。 例如： I lived in Canada in 2023. (过去住在加拿大，现在可能不住了。) I have lived in Canada for 10 years. (现在还住在加拿大。) I was a teacher at that time.(过去是一个老师，现在可能不是了。) I have been a twacher for 9 years.(现在还是老师。) （★Tips: 现在完成时与一般过去时都表示在过去发生的动作，但现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等。而一般过去时只表示过去的事实，不表示和现在的关系。所以，表示过去固定时间的状语只能与一般过去时连用，而不能与现在完成时连用。） (3) 现在完成时还可以表示一个动作到现在为止发生过多少次。 常带有twice, ever, never, three times等时间状语。 例如： I have already read this book three times. 这本书我已经看过三次了。 I have been to Beijing twice.我去过北京两次。 ★对多少次提问要用：How many times 二 现在完成时标志词： for+时间段； since+时间点 / 时间段ago / 从句(过去时)； 2. already（肯定句）, yet（否定句，疑问句）； ever（疑问句或者含有最高级、序数词的定语从句）； before, just ,recently, lately； 3. never, once, twice, three/four times...； 4. in recent years, in the past few years, in the last five months； 5. up to now,ever since, since then, so far（到目前为止）； 6. these days/years. 三 现在完成时公式： 主语 + have / has + Ved + 其他（have\has为助动词，有人称变化） 四 现在完成时句式： 肯定句: 主语 + have / has + 过去分词 + 其他 否定句: 主语 +have / has + not + 过去分词 + 其他 一般疑问句: --Have / Has + 主语 + V-过去分词 + 其他？ - Yes, 主+ have / has. （肯定回答） --No, 主+ haven’t / hasn’t.（否定回答） 特殊疑问句: 特殊疑问词 + 一般疑问句(have / has……) 练习： 1.
