(在团内的状态可延续) He has been a League member for three years. (是团员的状态可持续) 句子中如有过去时的时间副词(如yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。 (错)Tom has written a letter to his parents last night. (对)Tom wrote a letter to his parents last night. 返回动词的时态目录 11.11 用于现在完成时的句型 1)It is the first / second time.... that…结构中的从句部分,用现在完成时。例如: It is the first time that I have visited the city. 这是我第一次访问这城市。 This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。 注意:It was the third time that the boy had been late. 2)This is +形容词最高级+that…结构,that 从句要用现在完成时。例如: This is the best film that I've (ever) seen. 这是我看过的最好的电影。 典型例题 (1) ---Do you know our town at all? ---No, this is the first time I ___ here. A. was B. have been C. came D. am coming 答案B. This is the first time 后面所加从句应为现在完成时,故选B。 (2) ---Have you ____ been to our town before? ---No, it's the first time I ___ here. A. even, come B. even, have come C. ever, come D. ever, have come 答案D. ever意为曾经或无论何时,反意词为never,此两词常用于完成时。 注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。 (错)I have received his letter for a month. (对)I haven't received his letter for almost a month. 返回动词的时态目录 11.12 比较since和for Since 用来说明动作起始时间,for用来说明动作延续时间长度。例如: I have lived here for more than twenty years.我住在这儿二十多年了。 I have lived here since I was born. 我从出生起就住在这儿了。 注意:并非有for 作为时间状语的句子都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for many years.(现在我仍在这里工作。) 注意:用句型转换的方法,很容易排除非延续动词在有for/since结构的完成时中的误用。 1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now. 显然,第二句不对,它应改为 Harry got married six years ago. 或 Harry has been married for six years. 返回动词的时态目录 11.13 since的四种用法 1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。例如: I have been here since 1989. 1989起,我一直在这儿。 2) since +一段时间+ ago。例如: I have been here since five months ago. 我在这儿,已经有五个月了。 3) since +从句。例如: Great changes have taken place since you left. 你走后,变化可大了。 Great changes have taken place since we were here. 我们走后,变化可大了。 4) It is +一段时间+ since从句。例如: It is two years since I became a postgraduate student. 我考上研究生有两年了。 返回动词的时态目录 11.14 延续动词与瞬间动词 1) 用于完成时的区别 延续动词表示经验、经历; 瞬间动词表示行为的结果,不能与表示段的时间状语连用。例如: He has completed the work. 他已完成了那项工作。 (表结果) I've known him since then. 我从那时起就认识他了。(表经历) 2) 用于till / until从句的差异 延续动词用于肯定句,表示"做……直到……" 瞬间动词用于否定句,表示"到……,才……"。例如: He didn't come back until ten o'clock. 他到10 点才回来。 He slept until ten o'clock. 他一直睡到10点。 典型例题 1. You don't need to describe her. I ___ her several times. A. had met B. have met C. met D. meet 答案B. 首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several times告知为反复发生的动作,因此用现在完成时。 2. ---I'm sorry to keep you waiting. ---Oh, not at all. I ___ here only a few minutes. A. have been B. had been C. was D. will be 答案A. 等待的动作由过去开始,持续到现在,应用现在完成时。 返回动词的时态目录 11.15 过去完成时 1) 概念:表示过去的过去 ----|----------|--------|----> 其构成是had +过去分词构成。 那时以前 那时 现在 2) 用法 a. 在told, said, knew, heard, thought等动词后的宾语从句。例如: She said (that)she had never been to Paris. 她告诉我她曾去过巴黎。 b. 状语从句 在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。例如:When the police arrived, the thieves had run away. 警察到达时,小偷们早就跑了。 c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"。例如: We had hoped that you would come, but you didn't. 那时我们希望你能来,但是你没有来。 3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。例如: He said that he had learned some English before. 他说过他以前学过一些英语。 By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年,爱迪生开始自己谋生。 Tom was disappointed that most of the guests had left when he arrived at the party. 汤姆失望了,因为他到达晚会时,大部分客人已经走了。 典型例题 The students ___ busily when Miss Brown went to get a book she ___ in the office.
