八年級英語下學(xué)期現(xiàn)在完成時-免費閱讀
【正文】 現(xiàn)把這種時態(tài)的用法簡單的總結(jié)一下，和各位老師共同切磋。 Xiao Ming has been a soldier for half a year. Xiao Ming joined the army half a year ago. 8年學(xué)了。 Mr Black has been dead for three years. Mr Black died three years ago. ?，F(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(xué)們掌握起來比較困難。 Our teacher has left. We have studied English. I have already finished the homework. He has had his lunch. He has bee a doctor. 我們老師已經(jīng)離開了 . Our teacher has been away. (F) Our teacher has left.(T) 錯誤的認識 : (1)必須使用延續(xù)性動詞 . (2) 延續(xù)性動詞必須和一段時間連用 . have/has+過去分詞 ,一直持續(xù)到現(xiàn)在 ,還有可能持續(xù)到將來 .動作的持續(xù)性要通過一段時間來表示 . 一段時間的表達方法
