常見錯誤
What are common mistakes with "Occasionally"?Which "Occasionally" sentences look correct but are wrong?
×He is an occasionally visitor.
✓He is an occasional visitor.
「occasionally」是副詞，用來修飾動詞、形容詞或其他副詞，不能修飾名詞。修飾名詞（如 visitor）應使用形容詞「occasional」。
×I occasionally go to the cinema, maybe once a year.
✓I rarely go to the cinema, maybe once a year.
「occasionally」表示「有時、偶爾」，頻率比「rarely」（很少）高。若事件發生的頻率極低（如一年一次），使用「rarely」或「seldom」更為準確。
×She very occasionally visits her grandparents.
✓She very rarely visits her grandparents.
雖然「occasionally」可以受「very」修飾（如 very occasionally），但在口語中較不自然，且可能造成語意模糊。若要強調頻率極低，使用「very rarely」或「hardly ever」更為常見且清晰。
×Occasionally I will, when I have time, go for a walk.
✓I will occasionally go for a walk when I have time.
「occasionally」作為頻率副詞，通常置於主要動詞之前（如 will occasionally go），或句首、句尾。不應插入在助動詞與主要動詞之間（如 will, ... , go），這會破壞句子結構的流暢性。
×I go to the gym sometimes, but not occasionally.
✓I go to the gym occasionally, but not regularly.
「occasionally」和「sometimes」在頻率上相近，常可互換，但語意重點不同。「occasionally」強調不頻繁、非規律性，而「sometimes」僅表示「有時」。此錯誤在於將兩者對立使用，邏輯不通。應使用「regularly」（規律地）或「often」（經常）來與「occasionally」形成對比。
