用法筆記

This adjective is commonly placed before the noun it describes (attributive position), as in 'compulsory education' or 'compulsory military service'. However, it also works naturally after a linking verb like 'is' or 'became' in a predicative pattern, e.g. 'Voting is compulsory in Australia.'

常見錯誤

❖ 'It is compulsory to attend the meeting.' ✅ 'Attendance at the meeting is compulsory.' — 'compulsory' describes the event, rule, or thing itself, not the action someone takes.

❖ 'I have compulsory to finish the report.' ✅ 'It is compulsory to finish the report.' OR 'Completing the report is compulsory.' — 'compulsory' is an adjective and cannot replace the modal verb phrase 'have to'.
