(1)由should/would + 動(dòng)詞原形構(gòu)成。第一人稱用should; 第二、三人稱用would。美國(guó)英語(yǔ)所有人稱一律用would. should/would 的簡(jiǎn)略形式為’d, 如I’d, you’d; would not 和should not的簡(jiǎn)略形式分別為wouldn’t 和shouldn’t.
    (2)過(guò)去將來(lái)時(shí)表示從過(guò)去某時(shí)間看將要發(fā)生的事情，多用在賓語(yǔ)從句中。還可以表示過(guò)去的傾向或過(guò)去經(jīng)常發(fā)生的事情。如：
    They asked me if I would go to Guangzhou soon. 他們問(wèn)我是否很快要去廣州。
    She told me she would come again next week. 她和我說(shuō)她下周還來(lái)。
    I told him to leave immediately, but he wouldn’t. 我告訴他馬上離開(kāi)，但他不。
    He’d play the violin when he was in low spirits. 他情緒低落的時(shí)候，就拉小提琴。
    When I was in college, I would find a part-time job during the summer holidays every year to earn my tuition. 我上大學(xué)的時(shí)候，每年暑假都找份臨時(shí)工掙學(xué)費(fèi)。
