　　備考現(xiàn)在完成時的六個要點

　　現(xiàn)在完成時是初中英語中最重要也是最難掌握的一個時態(tài)，同時它也是中考英語中一個最重要的時態(tài)考點，許多同學們對現(xiàn)在完成的用法似懂非懂，具體做題時 也往往是跟著感覺走。本文結合初中英語的教學內容和中考英語的考查特點，為同學們歸納學好定語從句必須注意的五個方面，供大家參考。

　　一、弄清基本構成方法

　　現(xiàn)在完成時由“have / has+過去分詞”構成。其中的have / has 為助動詞，構成疑問句時，可將其提前；構成否定句時，可直接在其后加not。

　　二、掌握兩種主要用法

　　現(xiàn)在完成時主要有兩種用法，一種是已完成用法，也叫影響性用法；另一種是未完成用法，也叫持續(xù)性用法。兩種用法的特點是：

　　1. 已完成用法(影響性用法)：該用法的現(xiàn)在完成時表示一個過去發(fā)生的動作在過去已經完成，并且這個過去發(fā)生并完成的動作對現(xiàn)在有影響或結果，同時說話強調的或感興趣的就是這個影響或結果。如：

　　She has left. 她離開了。(對現(xiàn)在的影響或結果：她現(xiàn)在不在這兒。)

　　Has she found her car key? 她找到她的車鑰匙了嗎?(對現(xiàn)在的影響或結果：她能開她的車了嗎?)

　　I have finished my work. 我的工作做完了。(對現(xiàn)在的影響或結果：現(xiàn)在我沒事了。)

　　He has eaten nothing today. 他今天什么也沒吃。(對現(xiàn)在的影響或結果：他現(xiàn)在一定很餓。)
