初中英语复习资料：现在完成时总结及习题

这是一份初中英语复习资料：现在完成时总结及习题，共6页。试卷主要包含了易丢掉have/has，have与has易用混，延续性动词与短暂性动词易弄错，在条件等内容，欢迎下载使用。

2)过去已经开始，一直持续到现在的动作或状态。注意：此时动作可能还要继续。（即它的＂未完成用法＂）。E.g. He has lived in Beijing fr ten years.
其结构是“have/has+过去分词”。过去分词的变化分规则与不规则两种。规则变化与过去式相同，不规则变化需要另记。
它的否定句是在have/has后边加nt，变一般疑问句是把have/has提前。E.g. I have ridden a hrse. I have nt ridden a hrse. Have yu ridden a hrse?
它的时间状语通常为already, just, yet, ever, never, befre等。另外还可和since+表过去的时间点，fr+时间段连用。
做题时常见错误如下：
一、易丢掉have/has
例：He taken (take) the medicine befre.
答案：has taken
解析：have/has 为助动词，起构成时态的作用，是不能省略的。我们可以这样记：“现在完成时态中，have/has 不可缺。”
二、have与has易用混
例：I has never heard (hear) f that befre.
答案：have heard
三、延续性动词与短暂性动词易弄错
例：She has left (离开) fr 2 hurs.
答案：has been away
解析：在肯定句中，与since或fr引出的时间状语连用的是延续性动词，不能是短暂性动词，但在否定句中短暂性动词也是可以的。E.g. I haven't bught clthes fr ne year. 在此题中leave是短暂性动词，不能与fr+时间段连用，须把它改成相应的延续性动词。如stp be ver等。此题中leave要改成be away。这两种词的转换是学习现在完成时需要注意的。

四、have been t与 have gne t 易弄混
例：我去过北京。
I have gne t Beijing.
答案：I have been t Beijing.
解析："have been t+地点" 是表示曾去过某地，但此刻不在那儿（即在说话的地方）。而"have gne t+地点" 是表示去某地了，此刻在路上或已经到了那个地方（即不在说话的地方）。注意：这两个句式后接副词时，需省t。E.g. He has gne there.
五、 忘记把already变成yet
例：I have already finished my hmewrk.(变一般疑问句)
Have yu already finished yur hmewrk?
答案：Have yu finished yur hmewrk yet?
解析：现在完成时态中，肯定句中有already，变否定句或疑问句时通常要改为yet．
六、在条件、时间状语从句中用一般现在时表示将来
例：I'll g with yu when I finish(finish) my hmewrk.
答案：have finished
解析：在条件、时间状语从句中表示将来完成的动作，用现在完成时。但注意，此时表示这动作将在另一动作之前完成，若两动作同时发生，或几乎同时发生，则一般不用现在完成时。
另外，现在完成时易与一般过去时弄混，前边已经讲过,这里不在重复。
