toxic to do vs toxic doing
- 當 toxic 用來描述某種行為或活動本身具有毒性或危害性時，通常使用 toxic doing（動名詞）的形式，強調該行為的普遍性質。
- 當 toxic 用來描述某個特定情況、物質或環境對人體或事物「會造成毒害」時，則常使用 toxic to do（不定詞）的形式，強調其潛在的負面影響或後果。

常見錯誤
What are common mistakes with "Toxic"?Which "Toxic" sentences look correct but are wrong?
×The toxic of the chemical is high.
✓The toxicity of the chemical is high.
「toxic」是形容詞，意為「有毒的」。當需要表達「毒性」這個名詞概念時，應使用其名詞形式「toxicity」。
×That snake is very toxic.
✓That snake is very poisonous.
「toxic」通常指化學物質或人造物（如廢氣、廢水）的有毒性。對於動植物本身具有的、透過攝入或接觸使人中毒的天然毒性，更常用「poisonous」。
×He works in a toxic environment for his health.
✓He works in an environment that is toxic to his health.
原句結構容易造成語意混淆，讓人誤解「for his health」是修飾「environment」。使用關係子句或「toxic to...」的結構能更清晰地表達「對健康有害的」這個意思。
×My math homework is toxic.
✓My math homework is very difficult / frustrating.
「toxic」用於比喻時，通常描述對心理或情感健康有害的人際關係、文化或行為（如 toxic relationship, toxic positivity）。直接用來形容「作業」並不自然，會顯得像過度延伸或誤用這個比喻。
×This substance is toxic.
✓This substance is toxic. / The substance is toxic.
原句文法上正確，但在許多情境下會顯得不自然。當首次提及或泛指某個物質時，應使用不定冠詞「a」或指示詞「this/that」。只有在上下文已明確指涉特定物質時，才適合單獨使用「the substance」。此錯誤凸顯了中文母語者常忽略英文冠詞使用的問題。
