用法筆記
The conjunction 'that' after 'make sure' is optional and frequently omitted, especially in spoken English. The to-infinitive pattern ('make sure to do something') is common in instructions and warnings. 'Make sure' is not usually followed by a bare infinitive — ❌ 'make sure lock the door' is incorrect.
