初中英语语法总结三

来源:网络    作者:匿名    2009-10-26 15:14:14

标签:语法 英语说两句

  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.

  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.

  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。

  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。
