初中英语现在完成时用法及综合练习
现在完成时的构成：助动词have（has）+ 过去分词
1．表示过去发生或完成的某一动作对现在造成的影响或结果。例如：
I have just cleaned my clothes. 我刚洗过衣服。（“洗衣服”是发生在过去的动作，对现在造成的结果是“衣服干净了”）
现在完成时常用的时间状语有： already （”已经” 用于肯定句的中间和末尾处）
never (“从不” 用于中间处)
ever （”曾经” 用于疑问句和肯定句的中间处）
just (“刚刚” 用于中间处)
yet (“已经” 用于疑问句的末尾处 / “还” 用于否定句的末尾处)
或不加任何的时间状语，但不能和表示过去的时间状语连用.
现在完成时与一般过去时的用法比较
现在完成时表示过去的动作一直延续到现在甚至会继续下去或表示过去的动作对现在造成的影响，强调的是影响；一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作。试比较：The plane has arrived . 飞机已经来了。（说明现在的情况：飞机在这儿）The plane arrived a quarter ago. 飞机是一刻中以前来的。（强调动作发生的时间在过去）I have taught here for fifteen years. 我在这儿已经教了十五年。（表示十五年前的动作一直延续到现在，还可能会继续。）I taught here for a year. 我过去在这儿教过一年。（表示“我“现在已经不在这儿任教了）
一般过去时 常与具体的表示过去的时间状语连用; 现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语: yesterday, last week，…ago, in1990, in October, just now等-- 具体的时间状语 现在完成时的时间状语: for, since, so far, ever, never, just, yet, till/until, up to now, in the past few years, recently, … --模糊的时间状语
句子中如有过去时的时间副词（如 yesterday, last, week, in 1960）时，不能使用现在完成时，要用过 去时
（错）Tom has written a letter to his parents last night. （对）Tom wrote a letter to his parents last night.
