2) 現(xiàn)在完成時(shí)常與模糊的時(shí)間狀語連用(如for, since, so far, ever, never, just, yet, till/until, up to now, always等),或者干脆沒有時(shí)間狀語;
而一般過去時(shí)常與具體的時(shí)間狀語連用(如yesterday, last night, …ago, in 1980, in February等)。
3) 現(xiàn)在完成時(shí)表示持續(xù)時(shí)一般使用延續(xù)性動(dòng)詞(如live, teach, work, know等);
而一般過去時(shí)常使用瞬間動(dòng)詞(如begin, buy, die, marry等)。如:
