現(xiàn)在完成時與一般過去時比較課件

現(xiàn)在完成時與一般過去時比較一般過去時和現(xiàn)在完成時的區(qū)別：現(xiàn)在完成時是表示過去的動作與現(xiàn)在的聯(lián)系，主要說明的是現(xiàn)在的情況和狀態(tài)；而一般過去時則強調(diào)動作發(fā)生在過去某一時間，與現(xiàn)在不發(fā)生聯(lián)系.e.g.Wehaven‘tseenhimsincelastyear.我們自從去年以來一直未見到他。（現(xiàn)在還未見到）Wedidn‘tseehimlastyear.我們?nèi)ツ隂]見到他。（現(xiàn)在不一定未見到）Whohasopenedthedoor?誰把門開了？（現(xiàn)在門還開著）Whoopenedthedoor?誰開的門？(指過去，與現(xiàn)在無關(guān)?，F(xiàn)在門是關(guān)著還是開著，沒有說明。)—Haveyouhadyourlunch?你吃過午飯沒有？（意即你現(xiàn)在不餓嗎？）
