新概念英语第二册第65课语法知识点 Grammar in use
表示"应该"和"必须"的情态助动词 should, ought, have to 与must
(1)在第17课的语法中,我们学习了表示不可逃避的义务或表示"必须"的must。must通常只用于现在时和将来时,其他时态则用 have to代替。have to比 must往往更强调客观的要求或外在的原因:
In the play, she must appear in a bright red dress and long black stockings.演出时她必须穿一条鲜红色的裙子和黑色的长筒袜。
Last year in another play, she had to wear short socks and a bright, orange-coloured dress.去年在演另一个剧时,她不得不穿短袜和一件鲜艳的橘红色的衣服。
(2)should 和 ought to都可译为"应该",表示义务、责任或某个正确的行为。ought to比 should语气略强些,多用于肯定句;疑问句与否定结构则多用 should。与它们相比, must和 have to 的语气要强得多,没有选择余地:
(3)had to表示过去必须做某事,而 should/ought to+have+过去分词则表示过去应该做(或完成)而没有做的事
