【正文】 He left here three years ago. 二、用“ It is +一段時間＋ since ＋一般過去時從句 ” It is three years since he left here. 三、用“ 一段時間＋ have/ has passed + since + 一般過去時從句” Three years have passed since he left here. 以上三種表示方法適用于所有瞬間動詞。具體辦法是將瞬間動詞轉(zhuǎn)化為表延續(xù)的動詞或者表狀態(tài)的 be+名詞／形容詞或副詞／介詞短語等。 Mr Black has been dead for three years.
