exposure to formaldehyde
exposure to 是固定搭配，to 为介词，后接名词。

contain formaldehyde
contain 是及物动词，直接接宾语，不接介词。

Common mistakes
The room smells formaldehyde.The room smells of formaldehyde.
动词smell表示“散发…气味”时是不及物动词，不能直接接名词作宾语；要表达“有…的气味”需用smell of + 物质。所以应说smells of formaldehyde。注意与及物用法smell sth（闻到某物）相区别。
Formaldehyde harms to the human body.Formaldehyde harms the human body.
动词harm是及物动词，直接接宾语，中间不能加介词to；这是受harmful to搭配影响而产生的错误。应说harm the body，而不是harm to the body。

Pronunciation & Spelling
