3、在完成時非常常用 但比較難是否學好現(xiàn)在進行時，事關五種時態(tài)的學習：過去完成時將來完成時現(xiàn)在完成進行時過去完成進行時將來完成進行時現(xiàn)在完成時非常常用 但比較難一、形式 have/has + done(過去分詞)二、用法完成的含義？不要望文生義完成 現(xiàn)在全部完成 現(xiàn)在部分完成現(xiàn)在的之前（不管這事做沒做完）只要站在現(xiàn)在的時間點回頭看過去，不管這事做沒做完 都可以用現(xiàn)在完成時一、形式他走了。He has left.（現(xiàn)在全部完成）我們學英語十年了。We have learned English for ten years.（現(xiàn)在部分完成） 以后還要繼續(xù)學三、否定 疑問助動詞+not助動詞提前他走了。H

4、e has waited for three hours. 現(xiàn)在完成他現(xiàn)在的之前等了三個小時。他現(xiàn)在還在么？不一定結論：等完 沒等完這句話容易發(fā)生歧義。具體情況可根據(jù)上下文判斷。如果沒有上下文呢？創(chuàng)造一個新時態(tài)現(xiàn)在完成進行時He has waited for three hours.現(xiàn)在完成進行時即在現(xiàn)在完成時的基礎上，強調這事還沒做完，還在進行。這個時態(tài)就彌補了現(xiàn)在完成時的缺陷公式：have /has+been+doing用法：發(fā)生在現(xiàn)在的之前，還在進行eg：He has left.(現(xiàn)在全部完成)We have learned English for ten years.(現(xiàn)在部分完成)這

7、just +d現(xiàn)在完成時和一般過去時的區(qū)別1、He has left.現(xiàn)在全部完成 可以換成一般過去時=He left.區(qū)別在于 看待事物的角度現(xiàn)完：站在現(xiàn)在看過去一過：站在過去看過去現(xiàn)在完成時和一般過去時的區(qū)別1、He has left.應用：如無明確要求，兩種均可。如有要求，要根據(jù)看待事物的角度進行選擇考試中，出現(xiàn)對現(xiàn)在有明確影響的，用現(xiàn)完 他離開了，所以現(xiàn)在我找不到他了He _,so I cant find him now. has left 他離開了兩個小時。He _two hours ago. left應用：對于第二種情況，現(xiàn)在部分完成，不能換成一般過去時,因為二者意思完全不同We
