答案:B
解析:
|
現(xiàn)在完成時(shí)與一般過去時(shí)容易混淆,就是因?yàn)樗鼈兯硎镜膭?dòng)作都發(fā)生在過去,但二者又有區(qū)別:一般過去時(shí)表示過去某個(gè)時(shí)間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動(dòng)作,說話的側(cè)重點(diǎn)在于陳述一件過去的事情,與現(xiàn)在沒有關(guān)系;現(xiàn)在完成時(shí)表示與現(xiàn)在有關(guān)系的、發(fā)生在過去的動(dòng)作,它不與表示過去的時(shí)間狀語(如yesterday,last week,a moment ago等)連用。故答案為B。
