      英語中助動詞should, would的用法

        助動詞:輔助其他動詞構成時態(tài)、語態(tài)、疑問句式、否定名式的動詞。助動詞有些詞義,有些沒有詞義,或者暗含一點詞義。放在謂語首位置助動詞會受主語人稱、數(shù)的限制,其他位置不會受限制。

        should, would用來表示過去將來時態(tài),should用于第一人稱,would用于第二、三人稱(在美國也可用于第一人稱):

        I said I should turn in the exercise book the next day.

        我說我將在第二天交作業(yè)本。

        He asked whether they would come back that evening.

        他問他們是否當天晚上回來。

        should和would常用于虛擬語氣中:

        If it should rain tomorrow, I would stay at home.

        如果明天下雨,我會待在家里。

        If he should come back, we would welcome him.

        要是他回來,我們會歡迎他。

        Put on your raincoat in case it should rain.

        穿上雨衣,以防下雨。

        should表示驚訝和“應該”:

        It surprised us that he should have failed in the test.

        他竟然測試沒過關,我們感到很驚訝。

        Why should he have made such a big mistake?

        他怎么會犯這么大的錯誤呢?

        You should have informed me two days in advance.

        你們應該提前兩天通知我。

        We should learn from and help each other.

        我們應該互相學習,互相幫助。

        would常用于委婉、客氣地提建議、請求:

        Would you help me serve tea?

        你幫我上荼好嗎?

        What would you like to eat?

        你想吃點什么呢?

        I’d like some vanilla ice-cream.

        我想要些香草冰淇淋。

        would同will一樣常用于表示習慣或者傾向:

        When she was free, she would go shopping.

        她有空時就會逛商店。

        When asked a very simple question, he would laugh it off.

        當有人問他一個很簡單的問題時,他會一笑了之。
