C解析時(shí)態(tài)的呼應(yīng),有一些從句，特別是在賓語(yǔ)從句中，謂語(yǔ)動(dòng)詞的時(shí)態(tài)經(jīng)常受主句謂語(yǔ)動(dòng)詞時(shí)態(tài)的影響。說(shuō)話人必須使之一致，如：I did not know you were here。本來(lái)you were here 該用you are here。但由于受did not know的影響，就要用you were here。這種現(xiàn)象就叫時(shí)態(tài)的呼應(yīng)，如下列句子：He told us that he would go abroad. 他告訴我們他要出國(guó)。
