【正文】 如： e, go, buy, die, 等。 延續(xù)行動詞 是指那些動作意義不會一下完成，而是可以延續(xù)、發(fā)展的動詞。 I have taught this class for ten years. （還在教） I taught this class for two years. （曾教過兩年，現(xiàn)在不教了） . We have had the book for three years. . He has had a cold for three days. We bought the book three years ago. He caught a cold three days ago. 一般過去時態(tài)和現(xiàn)在完成時態(tài)同義轉(zhuǎn)換 . I have kept the book for a week . . I have been a student for over two years. I borrowed the book a week ago. I became a student two years ago. Black死了三年了。 I saw Mary an hour ago. She lost her handbag yesterday . 有些時間狀語，既能用于現(xiàn)在完成時，又能用于一般過去時，但意義上有差別。 常與 since或 for連用 (動作的持續(xù)性要通過一段時間來表示 ) . Kate has lived here for 3 years. Kate has lived here since 3 years ago. Kate has lived here since she came to China for 和 since的運用對比 : for: +一段時間 for two weeks for three years since 過去的某一時刻 since then since last month 一般過去時態(tài)的時間狀語從句 since she left 注意 :for 和 since 所引導的時間狀語都 表示一段時間 . He has been away for a week. He has been away since last week. 對劃線部分提問都用How long 現(xiàn)在完成時態(tài)是中考的必考時態(tài)，由于現(xiàn)在完成時態(tài)既涉及到過去，又聯(lián)系到現(xiàn)在，和一般過去時態(tài)，一般現(xiàn)在時態(tài)，現(xiàn)在進行時態(tài)既有聯(lián)系，又有 區(qū)別，所以同學們掌握起來比較困難。常與 yet 或 already連用。 如： Have you ever been to Hong Kong? I’ ve never traveled by air. 用 法 I have already written to her. She hasn’ t spent much time on it yet. 表示剛剛發(fā)生過的動作或事情 ， 常與just連用 。Wele to our class
