2023年中考英语现在完成时重点知识及习题

现在完成时表示1)过去发生或已经完成的动作或存在的状态对现在造成的影响或结果.(即它的"完成用法")e.g. I have just cleaned the classroom.

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 for 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not，变一般疑问句是把have/has提前。E.g. I have ridden a horse. I have not ridden a horse. Have you ridden a horse?

它的时间状语通常为already, just, yet, ever, never, before等。另外还可和since+表过去的时间点，for+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 before.

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) of that before.

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) for 2 hours.

答案：has been away

解析：在肯定句中，与since或for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 bought clothes for one year. 在此题中leave是短暂性动词，不能与for+时间段连用，须把它改成相应的延续性动词。如stop be over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 to与 have gone to 易弄混

例：我去过北京。

I have gone to Beijing.

答案：I have been to Beijing.

解析："have been to+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 gone to+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to。E.g. He has gone there.

五、 忘记把already变成yet

例：I have already finished my homework.(变一般疑问句)

Have you already finished your homework?

答案：Have you finished your homework 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 go with you when I finish(finish) my homework.

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。
