배울 내용
안녕하세요! 이제 기초를 넘어 상대방의 마음을 움직이는 '조언과 지시'의 기술을 배울 차례예요. 일상생활에서 친구에게 맛집을 추천하거나, 직장에서 동료에게 업무 지침을 전달해야 할 때가 정말 많죠? 이번 챕터에서는 가벼운 권유를 나타내는 'should'와 강력한 의무를 표현하는 'must'의 미묘한 차이를 완벽하게 마스터할 거예요. 단순히 단어만 배우는 게 아니라, 'If'와 결합해 '만약 ~라면 이렇게 하세요'라는 조건부 조언(If + should)과 명령(If + imperative)까지 깊이 있게 다룹니다. 예를 들어, 'If you're tired, you should take a break(피곤하면 좀 쉬어야 해요)'처럼 상황에 맞는 다정한 조언은 물론, 'If the fire alarm rings, leave the building(화재 경보가 울리면 건물 밖으로 나가세요)' 같은 긴급한 지시도 막힘없이 할 수 있게 돼요. 이 챕터를 끝내고 나면, 단순히 문장을 만드는 수준을 넘어 원어민처럼 상황의 무게감에 맞춰 적절한 톤으로 의견을 제안하고 가이드할 수 있는 능력을 갖추게 될 거예요. 자, 이제 더 설득력 있는 영어 대화를 시작해 볼까요?

챕터 가이드
Overview
You should try that new cafe.You'll also master must for those times when something is truly essential, as in
You must submit your report by Friday.We’ll also explore how to combine these with the first conditional – using
if clauses to give advice and commands that are relevant to specific situations, such as If you want to pass the exam, you should study every dayor
If you see a problem, tell your manager immediately.By the end, you'll be confidently guiding others and understanding important directions like a native speaker.
How This Grammar Works
You should drink more wateror
They should call their parents more often.It implies a good idea, but the choice is still up to the listener.
All visitors must check in at receptionor personal vows like
I must finish this project tonight.If there’s no other option, or the consequences of not doing it are serious, must is the word.
If you feel tired, you should take a breakor
If it rains tomorrow, we should bring umbrellas.This makes your advice more practical and targeted.
should, you give a direct command or instruction in the second part of the sentence. The structure is: If + present simple, imperative (base verb form).If you arrive late, wait outsideor
If you have any questions, ask the teacher.This is perfect for giving clear, actionable instructions based on a potential future event. These structures together give you a powerful toolkit for guiding conversations and ensuring clarity in your interactions.
Common Mistakes
- 1✗ Wrong: You must try the new coffee shop. (Sounds too strong, like an order)
should for suggestions, not must, which implies a necessity or obligation.- 1✗ Wrong: If you want to lose weight, you must to exercise. (Incorrect grammar with
to)
must or should, always use the base form of the verb without to.- 1✗ Wrong: If it rains, you should to take an umbrella. (Incorrect grammar with

Quick FAQ
When should I use should versus must for advice?
Use should for advice, recommendations, or what's generally a good idea. It's a suggestion. Use must when there's a strong obligation, a rule, a necessity, or a strong personal conviction. It implies no real choice.
Can I use if with must?
While grammatically possible (e.g.,
If you must leave, please close the door), it's less common for *giving advice*. It usually expresses a resignation or necessity already acknowledged. For conditional advice, stick to
should or an imperative.
Is you should always polite?
Generally, yes, you should is polite. However, if used too frequently or with a lecturing tone, it can sometimes sound a little preachy. To soften it further, you can say
I think you should...or
Perhaps you should...
What's the difference between
If you want to...and
If you need to...when giving advice?
If you want to...implies a personal desire or goal (e.g.,
If you want to improve, you should practice daily).
If you need to...implies a requirement or necessity (e.g.,
If you need to contact me, call this number). Both are useful in conditional advice.
Cultural Context
You might want to...or
I suggest you...) even for important advice, to maintain a friendly tone.주요 예문 (8)

자주 하는 실수
Modal verbs like 'should' and 'must' are followed directly by the base verb. Never use 'to' after them.
In conditional advice, the second clause still needs a subject (you, he, she) before the word 'should'.
In the 'if' clause of a first conditional, we use the Present Simple, not 'will'.
