语法精析
初中阶段动词时态语态的用法汇总(二)
1.现在完成时的用法、构成和时间状语
用法 表示过去发生的动作对现在所造成的影响或产生的结果 。
基本结构 主语+have/has+过去分词+其他
时间状语 already , yet , ever , never , just , before , so far 等。 for和表示时间段的短语搭配since和表示过去某一时刻的词、短语连用。
We have already cleaned the classroom . 我们已经打扫过教室了。
She has worked in the factory since two years ago . 她从两年前就在这家工厂工作了。
2. 注意点
(1)通常情况下, 过去分词和过去式写法一致。但也有不一致的情况,如come 的过去式是came , 过去分词是come; drink的过去式是drank , 过去分词是drunk .
(2)现在完成时表示动作从过去某个时候开始一直持续到现在,与一段时间连用时应注意肯定句的谓语动词应是延续性动词,非延续性动词不能和一段时间连用。如:
我离开这所学校已八年了。
误:I’ve left this school for eight years.
正:I’ve been away from this school for eight years .
他借用我的词典已两天了。
误:He has borrowed my dictionary for two days .
正:He has kept my dictionary for two days .
(3 ) 当非延续性动词需要和时间段搭配时,可将非延续性动词(短语)转化为延续性动词(短语)或“be+形容词/副词”的结构 。如:
buy- have borrow – keep
open- be open close – be closed
start/begin- be on come – be here
finish -be over die – be dead
leave – be away join – be in/be a member of
They have been away for three months . 他们已经离开三个月了。
I have had the camera for one year . 这个照相机我买了一年了。
