Unit 6 Plan for Yourself
核心语法:情态动词 should, ought to, had better 表示建议
一、 核心概念
情态动词 should, ought to, had better 都用来向他人提出建议、劝告或意见,意为“应该”、“最好”。但它们的语气强弱和用法有所不同。
二、 用法详解
1. should
含义:应该。表示一种义务、责任或从常理上认为正确或明智的做法。是三个词中最常用、语气最中性的一个。
否定式:should not / shouldn't (不应该)
疑问式:将 should 提前至句首。
例句:You look tired. You should go to bed early. (你看起来很累。你应该早点睡觉。)-> 基于身体状况的合理建议。
We should respect our parents and teachers. (我们应该尊敬父母和老师。)-> 表达一种社会道德责任。
Should I wear a coat It's cold outside. (我应该穿件外套吗?外面很冷。)-> 征询意见。
He shouldn't eat so much junk food. It's unhealthy. (他不应该吃这么多垃圾食品。不健康。)-> 提出劝诫。
2. ought to
含义:应当,应该。语气比 should 稍强一些,更多地强调基于道德、规则或逻辑推理上的义务和责任。在实际口语中,不如 should 常用。
否定式:ought not to / oughtn't to (不应当)
疑问式:将 ought 提前至句首。(此结构不常见,通常用 should 提问)
注意:to 是固定搭配的一部分,不可省略。
例句:
You ought to apologize to her for what you said. (你为你所说的话应当向她道歉。)-> 基于道德礼仪的强烈建议。
He ought to be more careful with his work. (他应当更仔细地对待他的工作。)-> 基于工作职责的要求。
They ought not to waste water. (他们不应当浪费水。)-> 基于社会公德的劝诫。
3. had better
含义:最好。语气是三个中最强的,带有一种“强烈建议、警告或暗示如果不这样做可能会有负面后果”的含义。相当于中文的“你最好……(不然的话……)”。
缩写形式:'d better (口语和书面语中都极其常用)
否定式:had better not / 'd better not (最好别)
错误:~~had not better~~
疑问式:将 had 提前至句首。(不常用)
注意:had better 后面接动词原形。虽然形式是过去式(had),但永远表示现在或将来的含义。
例句:
You 'd better hurry up, or you'll miss the train. (你最好快点,否则要赶不上火车了。)-> 暗示错过火车的后果。
It's going to rain. We had better take an umbrella. (要下雨了。我们最好带把伞。)-> 暗示不然会淋湿。
You 'd better not be late for the meeting today. The boss is angry. (你今天开会最好别迟到。老板很生气。)-> 强烈的警告。
He had better stop smoking if he wants to get healthy. (他想健康的话,最好戒烟。)-> 暗示不戒烟的健康风险。
三、 核心对比与总结
情态动词 含义 语气强度 内涵与用法 否定式
should 应该 中等 (最常用) 提出一般性、合理的建议或意见。 should not / shouldn't
ought to 应当 较强 基于道德、责任、规则的义务。稍正式。 ought not to / oughtn't to
had better 最好 最强 (近乎警告) 在特定情况下,强烈建议采取行动以避免麻烦。 had better not / 'd better not
简单记忆:
普通建议用 should。
讲道理、论责任用 ought to。
快要出事、有麻烦了,用 had better 来警告。
四、 易错点提醒
1、had better 的时态:形式是过去,意义是现在或将来。
正:You had better do it now. (你现在最好就做。)
误:~~You have better do it now.~~ (had 不能换成 have)
2、had better 的否定:否定词 not 必须放在 better 之后,动词原形之前。
正:You had better not go. (你最好别去。)
误:~~You had not better go.~~
3、ought to 的 to:后面的 to 绝对不能省略。
正:You ought to see a doctor. (你应该去看医生。)
误:~~You ought see a doctor.~~
