用法說明
How is "Contaminated" different from similar structures?What usage mistakes are common with "Contaminated"?
contaminated with vs contaminated by
- contaminated with 通常用於指出污染物質的具體成分或類型，強調「含有」某種污染物。
- contaminated by 則更常強調污染的來源、媒介或原因，即「被...所污染」。
- 在許多情況下，兩者可以互換使用，但細微差別在於 with 聚焦於污染物本身，而 by 聚焦於污染過程或來源。

常見錯誤
What are common mistakes with "Contaminated"?Which "Contaminated" sentences look correct but are wrong?
×The water was contaminated by chemicals.
✓Chemicals contaminated the water.
Learners often use the passive voice when the active voice is more direct and natural, especially when the agent (the thing causing contamination) is known and important to the sentence.
×The air is contaminated with smoke.
✓The air is contaminated by smoke.
While 'contaminated with' is common for describing the state (e.g., 'water contaminated with lead'), 'contaminated by' is typically used to introduce the active agent or cause of the contamination, especially in passive constructions. Using 'with' for the agent is less precise.
×He contaminated the news with fake information.
✓He tainted the news with fake information. / He spread misinformation.
'Contaminate' is primarily used for physical substances (water, air, food, soil) or abstract things like data/samples. For abstract concepts like reputation, truth, or atmosphere, words like 'taint', 'corrupt', 'poison', or 'sully' are more idiomatic.
×I contaminated my phone with water.
✓I got water in my phone. / My phone got wet.
'Contaminate' implies making something impure or dangerous by adding a harmful substance. For common accidents like spilling water on a device, simpler and more natural phrases like 'got water in', 'got wet', or 'damaged with water' are used.
×The factory contaminates the river for years.
✓The factory has been contaminating the river for years.
When describing an action that started in the past and continues to the present, or has present results, the present perfect continuous tense ('has been contaminating') is required, not the simple present.
