Module 1 Unit 3 A visit to Garden City
现在完成时
现在完成时表示一个发生在过去的、对现在仍有影响的动作,或表示开始在过去,并且一直延续到现在,甚至还可能延续下去的动作。
①在完成时由“助动词have (has)+动词的过去分词”构成。
②表示发生在过去的对现在仍有影响的动作时,时间状语有：already, yet, just, once, twice,ever, never,three times, before，in the past few years等。如：I have never en such fine pictures before. (我以前从来没有看过这么好的画)/ He has just gone to England.(他刚去英国)
③表示在过去开始一直延续到现在(可能延续下去)的动作或状态时,时间状语有：for+一段时间，since+过去时间点和since引导的状语从句。如：I have been away from my hometo
wn for thirty years.(我离开家乡有30年了)/ Uncle Wang has worked in the factory since it opened.(自从这家工厂开张,王叔叔一直在那儿工作)
④have been to与have gone to的区别：have gone to(“已经去了”)表示人不在这里,have been to(“去过”)表示人在这里。如：--Where is Mr Li? –He has gone to the UK.(李先生在哪里？他去了英国。)/ --Do you know something about Beijing? –Yes,I have been to Beijing three times. (你知道北京的情况吗？是的,我去过那里三次。)
⑤在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语连用,此时须将该瞬间动词改为延续性动词或状态动词。具体变化见下表：
瞬间性动词的完成时 | → | 延续性动词或状态动词的完成时 |
have | (already) | gone to… | have | been in / at … | for (two years) |
has | | come to… | has | been here | since (1990) |
(had) | | left… | (had) | been away from… | |
| | arrived… | | been in… | |
| | died | | been dead | |
| | begun | | been on | |
| | ended | | been over | |
