In the process of learning English, modal verbs play a special role. Modal verbs are used to modify or reinforce the meaning of verbs and are primarily used to express possibility, necessity, ability, permission, advice, etc. In particular, the modal verbs that express advice and obligation are a very important part of English grammar, and through them, we can use appropriate expressions according to the situation.
What are Modal Verbs?
Modal verbs are verbs that assist the main verb and supplement its meaning. Important modal verbs in English include:
- can – can
- could – could
- may – may
- might – might
- must – must
- should – should
- would – would
These modal verbs each have unique meanings and usages, and should be appropriately chosen and used according to the context of the sentence. In this article, I will focus specifically on modal verbs related to advisability and necessity.
Modal Verbs that Indicate Advisability
Modal verbs that indicate advice primarily include should, ought to, and had better. Unlike other modal verbs, these are used when recommending a certain action to someone.
1. Should
Should is the most commonly used modal verb to express advice. It is mainly used when providing practical advice or recommendations.
Example: You should study hard for the exam.The above sentence expresses the recommendation that “you should study hard for the exam.”
2. Ought to
Ought to has a similar meaning to should but carries a slightly stronger nuance of advice. It is used to emphasize psychological or moral obligation.
Example: You ought to apologize for your mistake.This sentence means “it is right to apologize for your mistake” and provides stronger advice.
3. Had better
Had better expresses advice in more urgent situations. This expression carries implications of negative consequences if the advice is not followed.
Example: You had better finish your homework before going out.This sentence implies that “it is better to finish your homework before going out,” suggesting that problems may arise if you don’t.
Modal Verbs that Indicate Necessity
Modal verbs that indicate obligation primarily include must, have to, and need to. These emphasize that a certain action or situation is absolutely necessary.
1. Must
Must is a modal verb that expresses a strong sense of obligation. It emphasizes that action is necessary based on personal strong judgment.
Example: You must wear a seatbelt while driving.This sentence expresses a strong obligation that “you must wear a seatbelt while driving.”
2. Have to
Have to expresses obligation based on external demands or rules. This expression is used to emphasize essential necessity.
Example: I have to submit the report by Friday.This sentence expresses the external requirement that “I have to submit the report by Friday.”
3. Need to
Need to is used to express a less strong sense of obligation in a low-key manner. It indicates a necessity that has been raised by someone or something.
Example: You need to practice regularly to improve your skills.This sentence emphasizes the necessity that “you need to practice regularly to improve your skills.”
Examples of Using Modal Verbs
Now let’s look at how to structure conversations using modal verbs in different situations.
Situation: Giving advice to a friend about study methods for an exam
A: I’m really stressed about the upcoming exam.
B: You should take regular breaks while studying.
Situation: Expressing obligation to meet a deadline at work
A: I don’t have enough time to finish this project.
B: You have to submit it by the end of the week.
Situation: Giving health advice
