二、詞義辨析:


when,while,as

這些連詞均可表示“當(dāng)……時(shí)”引出時(shí)間從句。 when所引導(dǎo)的從句,其謂語(yǔ)動(dòng)詞既可是持續(xù)動(dòng)詞,也可是短暫動(dòng)詞;謂語(yǔ)動(dòng)詞動(dòng)作發(fā)生的時(shí)間可以與主句謂語(yǔ)動(dòng)詞的動(dòng)作是同時(shí),或之前、之后。 while句中的謂語(yǔ)動(dòng)詞應(yīng)為持續(xù)動(dòng)詞,不用短暫動(dòng)詞,謂語(yǔ)動(dòng)作發(fā)生的時(shí)間通常與主句謂語(yǔ)動(dòng)詞動(dòng)作發(fā)生時(shí)間是同時(shí)。 as側(cè)重指從句與主句的動(dòng)作同時(shí)進(jìn)行,謂語(yǔ)動(dòng)詞可以是持續(xù)性的,可以是短暫性動(dòng)詞。
