應該不應該(should)

🎯 這一課你會學會

給建議、講「應該/不應該」——用 should / shouldn't。它比 must 語氣軟,是「我覺得這樣比較好」,不是強制。學完你能給人建議、也能問人「我該怎麼辦?」

💬 先聽一段對話

Amy: I have a headache and I'm really tired.（我頭痛,而且好累。)
Ken: You should go home and rest. You shouldn't work so much.（你應該回家休息。不該工作那麼拚。)
Amy: You're right. Should I see a doctor?（你說得對。我該看醫生嗎?)
Ken: Maybe. If it's still bad tomorrow, you should.（也許。明天還是不舒服的話,就該去。)

🔑 關鍵句型

• should + 原形(應該):You should rest.
• shouldn't + 原形(不應該):You shouldn't worry.
• 問建議:Should I…?　Should I call her?
• 也常配 I think…:I think you should try.

🧩 文法點:should 怎麼用

① should = 建議、「我覺得比較好」,語氣比 must 軟:

• must / have to = 必須(沒得選)　vs　should = 應該(建議,還是有選擇)。
• You must stop at a red light.（強制)　You should drink more water.（建議)

② should 是情態動詞,規則跟 can / must 一樣:

• 後接原形:✅ You should see a doctor.　❌ should to see / sees。
• 所有主詞都用 should(不加 s):he should、she should…。
• 否定 shouldn't、問句把 should 提前:Should I go?

③ 常見用法:

• 給建議:You should talk to her.
• 問建議:What should I do?（我該怎麼辦?)
• 委婉不同意:I don't think you should do that.

📒 高頻單字

單字	KK 音標	中譯	例句
should	/ʃʊd/	應該	You should rest.（你該休息。)
rest	/rɛst/	休息	Get some rest.（休息一下。)

try	/traɪ/	試	You should try.（你該試試。)

🗣️ 發音提醒

• should /ʃʊd/:l 不發音,唸「shʊd」(像「書的」的短音),別唸出 l。
• shouldn't /ˈʃʊdənt/:同樣 l 不發音。
• advice /ədˈvaɪs/(名詞,結尾 /s/)vs advise /ədˈvaɪz/(動詞,/z/)——A2 先認名詞 advice。

✍️ 開口練習

練習 1:給建議(should / shouldn't)。

• 朋友很累 → You ＿ rest.（should)
• 朋友熬夜 → You ＿ stay up so late.（shouldn't）

練習 2:抓錯。

• ❌ You should to see a doctor. → ✅ You should see a doctor.
• ❌ She shoulds try. → ✅ She should try.

練習 3:給三個建議。

If you want to learn English, you should ＿. You shouldn't ＿.
