英语建议表达的情态动词课程 - TOEIC®备考

在备考TOEIC®时,掌握用情态动词表达建议的用法至关重要。在英语中,有多种表达方式可以用于建议或鼓励某人采取行动。最常见的表达有:should、ought to 和 had better。此外,像 could 或 might want to 这样的结构,也可以用来给出更加委婉或不那么直接的建议。
1. "Should" 用于给建议或推荐
A. “Should” 的使用场景
情态动词 “should” 用于给建议或提出建议。当你想建议某个行动或想法,认为它是在特定情境下最好的选择,但又不强加严格的义务时,可以使用“should”。无论是个人还是职场环境,“should”都是较为礼貌的选择。
- You should eat more fruits and vegetables.
(你应该多吃一些水果和蔬菜。) - I think you should call your parents more often.
(我认为你应该更常给父母打电话。) - Should we leave now or wait a bit longer?
(我们现在走还是再等一会儿?) - She should try to finish her project before the deadline.
(她应该试着在截止日期前完成她的项目。)
B. “Shouldn't” 的使用场景
“Shouldn’t” 是 should 的否定形式,用于建议不要做某事。它表达某个行为或态度不被推荐,或者可能带来负面结果。和“should”一样,“shouldn’t”也很礼貌,没有强制性,只是建议避免某些被认为不理想或有问题的行动。
- You shouldn’t worry so much about what people think.
(你不必太在意别人的看法。) - He shouldn’t spend all his money on unnecessary gadgets.
(他不应该把钱都花在没必要的小玩意上。) - They shouldn’t ignore the safety instructions.
(他们不应该忽视安全指示。)
C. “Should” 和 “Shouldn’t” 的时态用法
用于现在和近期未来
这是 should 和 shouldn’t 的主要用法。用于给出当前或即将发生情境下的建议或建议。
- You should study for the test tomorrow.
(你明天考试应该复习一下。) - You shouldn’t eat so much junk food.
(你不应该吃那么多垃圾食品。)
用于过去时
使用 should have + 过去分词 或 shouldn’t have + 过去分词,可以表达遗憾、批评或过去本应采纳的建议。
- You should have called me earlier.
(你本应该早点给我打电话。) - He shouldn’t have spent so much money on that car.
(他不应该在那辆车上花那么多钱。) - They should have arrived by now.
(他们现在应该已经到了。)
2. “Ought to” 用于正式场合的建议
半情态动词 “ought to” 和 should 意思几乎一样,但更加正式。一般来说,“ought to” 在日常对话中用得较少。
- You ought to see a doctor if you keep feeling sick.
(如果你总是觉得不舒服,应该去看医生。) - He ought to pay more attention to the details.
(他应该更加关注细节。) - We ought to finish this report before going home.
(我们应该在回家前完成这份报告。) - You ought not to speak so rudely to your coworkers.
(你不应该对同事说话那么粗鲁。) - Ought she to call her boss now or wait until tomorrow?
(她现在应该给老板打电话还是等到明天?)
3. “Had better” 用于警告性建议
表达结构 “had better”(常缩写为 'd better)也是给建议的方式,但它比 should 更紧迫或更强烈。有时听起来甚至像是一种警告。使用这一结构时,通常如果不采纳建议会有负面后果。
在中文中,常可以翻译为“你最好......”或“最好......”。
- You’d better leave now if you don’t want to miss your flight.
(如果你不想错过航班,现在最好离开。) - He had better not forget his presentation.
(他最好别忘了自己的演讲。) - They’d better check the weather forecast before going hiking.
(他们最好在去徒步前查一下天气预报。) - You’d better call her right away, or she’ll worry.
(你最好赶快给她打电话,否则她会担心。) - We’d better study for the test tomorrow.
(我们最好复习一下明天的考试。)
4. “Could” 用于提出建议
情态动词 could 用于提出建议或想法,语气比 should 更轻、更委婉。常用于提供替代方案或表达可能性,而不是强烈建议。
- You could talk to your manager about getting a raise.
(你可以考虑和经理谈谈加薪的事。) - You could try a different approach for this project.
(你可以试试对这个项目采用不同的方法。)

5. “Might want to” 用于委婉建议
表达结构 might want to 用于非常委婉地给建议。尤其适用于希望保持礼貌或避免显得咄咄逼人的场合。这种表达方式提出建议时给对方很大选择空间。
- You might want to take a break if you feel tired.
(如果你觉得累了,可以考虑休息一下。) - They might want to consider hiring more staff.
(他们可以考虑多招一些员工。)
6. “Why don’t you...?” 用于建议想法
表达结构 Why don’t you...? 是口语中常见的反问表达,用于建议或提出解决方案。这是一个鼓励别人采取行动的好方法,不会让人感觉强加建议。
- Why don’t you join us for dinner tonight?
(今晚要不要一起吃晚饭?) - Why don’t you try calling customer service?
(要不要试着打电话给客服?)
7. “You’d be better off + V-ing / with something” 用于推荐
习语表达 You’d be better off 用于表述做某事后情况会更好。它提出一个看起来更有益或适合的替代方案。
结构 You’d be better off + V-ing
- You’d be better off spending your time on more productive tasks.
(你把时间花在更有成效的任务上会更好。) - We’d be better off finding a cheaper supplier.
(我们找一个更便宜的供应商可能更合适。)
结构 You’d be better off + with something
- You’d be better off with a reliable car for long trips.
(长途旅行时有一辆可靠的车会更好。) - They’d be better off with a more experienced team for this project.
(这个项目如果有经验更丰富的团队会更好。)

建议类情态动词要点和常见错误
-
与带“to”的动词混淆
- 提醒:should、ought to、had better、could、might want to,动词后一般用原形(除了ought to本身自带“to”)。
- 错误:You should to go. / 正确:You should go.
-
用“must”替代“should”
- Must 表示强制性或必要性,不建议用来给建议,因为过于严厉。
- 示例:You must finish this report by tonight.(几乎不可协商的要求)
- 建议表达:You should finish this report by tonight.
-
疑问句形式
对于 should,正确的疑问形式是:Should we wait here? 而不是 Do we should wait here?
-
否定用法
- 用 should:You shouldn’t eat so much junk food.
- 用 had better:You had better not stay up too late.
-
正式和非正式语境
有些表达如 had better 或 you'd be better off 在正式场合可能太直接。用 should 或 might want to 更适合专业场合。
- You had better submit the report today.(在正式场合太直接)
- You should submit the report today.(礼貌且合适)
-
用“Could”和“Might”表达更委婉的建议
这些情态动词可以更加温和地给建议,不太具强制性。非常适合避免显得专断。
