      英語時態(tài)學習:since謂語動詞的時態(tài)

      時間: 家志1175 分享

        學習啦:當since表示時間,謂語動詞的時候,since的時態(tài)應該怎么表達?下面我們一起看看這篇《since謂語動詞的時態(tài)》。

        一般情況下,since短語和since從句表示時間時,通常句子(或主句)謂語動詞用完成時。但是,在以下情況下,since短語與since從句表示時間時,句子(或主句)謂語動詞可以不用完成時:

        (1)句子(或主句)謂主動詞與情態(tài)動詞連用時,不用完成時。比如:

        Since the doctor operated on his throat, the boy can speak clearly.

        自從醫(yī)生給這男孩做過喉部手術后,他就能清楚地講話了。

        He can only stay in bed since he fell ill.

        他自從生病后,就一直臥床不起了。

        (2)當since引出的狀語修飾一個后置定語從句時,句子(或主語)不用完成時。比如:

        People were evacuated from the territories occupied (=which had been occupied) since the beginning of the war.

        人們被迫撤出了戰(zhàn)爭開始以來就被占領的領土。

        The couple had no photo of themselves taken (=which had been taken) since they got married.

        那對夫妻自從結婚后就沒照過相。

        (3)句子(或主句)謂語是be動詞,并且表示時間概念時,句子(或主句)謂語動詞用一般現在時比用現在完成時普遍。比如:

        It is (has been) three years since he joined the army.

        他參軍已經3年了。

        It is (has been) a long time since we parted.

        我們已分別久了。

        (4)有時句子(或主句)謂語動詞be也可用過去式,此時since從句的謂語動詞常用過去完成時。比如:

        It was two years since we had parted.

        我們分手有2年了。

        It was ages since I had had my last meat.

        我前一頓飯已經吃過好長時間了。

        (5)當所述是事實,或一種長期不變的習慣時,句子(或主句)謂語動詞常用一般現在時。比如:

        Ever sincehe recovered, he goes for an outing every other morning.

        自從他康復后,每隔一天早晨他都要到郊外遠足一次。

        My mother feels a lot better since she took the medicine.

        自從我母親服過那藥后,她感覺好多了。
