時(shí)間狀語從句的從屬連詞與句子的時(shí)態(tài)有一些通常需要遵從的規(guī)律，如果在使用時(shí)不注意，就很容易引起語意不明的問題，小編這就為大家介紹幾個(gè)與時(shí)間狀語從句有關(guān)的時(shí)態(tài)問題。

?

(1) 當(dāng)主句為將來時(shí)態(tài)或具有將來意義時(shí)，時(shí)間狀語從句通常要用一般現(xiàn)在時(shí)表示將來意義，而不能直接使用將來時(shí)態(tài)：

?Wash your hands thoroughly with hot soapy water before you handle any food. 在拿吃的之前，用熱肥皂水把手好好地洗干凈。

As soon as the two chicks hatch, they leave the nest burrow. 兩只小鳥一出殼就離開了巢穴。

(2) 與since 從句搭配的主句的時(shí)態(tài)通常是現(xiàn)在完成時(shí)態(tài)：

Rock'n'roll has become so commercialized and safe since punk. ?搖滾樂自從朋克樂以后就已經(jīng)過于商業(yè)化而缺乏新意了。

The nation's unemployment rate has been climbing steadily since last June. 自去年6月以來，該國的失業(yè)率一直在不斷上升。

【注】在特定的語言環(huán)境中有時(shí)也可能用過去完成時(shí)或一般現(xiàn)在時(shí)：

It seems like years since we last met. 我們似乎幾年未見面了。

?I've had the hots for him ever since he came to college. ?自從他來上大學(xué)后，我就對他春心萌動。
