常見錯誤
What are common mistakes with "Chemistry"?Which "Chemistry" sentences look correct but are wrong?
×I have a chemistry with my new colleague.
✓There is chemistry between me and my new colleague.
當「chemistry」指人與人之間的默契或吸引力時，是不可數名詞，前面不加冠詞「a」。通常使用「There is chemistry between...」或「We have chemistry.」的句型。
×I need to improve my chemistry knowledge.
✓I need to improve my knowledge of chemistry.
表示「某個學科的知識」時，通常使用「knowledge of + 學科名稱」，而不是將學科名稱作為形容詞放在「knowledge」前面。
×Chemistry is interesting subject.
✓Chemistry is an interesting subject.
當「chemistry」作為學科名稱時，是不可數名詞，前面不加冠詞。但當它後面接「subject」、「field」、「course」等可數名詞時，需要根據該可數名詞的單複數和語境使用適當的冠詞。
×The chemistries of these two compounds are very different.
✓The chemistry of these two compounds is very different.
當「chemistry」指物質的「化學性質、組成或反應」時，是不可數名詞，沒有複數形式。動詞應使用單數。
×I bought a new chemistry for the lab.
✓I bought new chemicals / chemical reagents for the lab.
「Chemistry」指的是化學這門學科或抽象的化學原理/互動，不是指具體的化學藥品。具體的化學物質應使用「chemicals」、「chemical reagents」、「compounds」等詞。
×She is major in chemistry.
✓She is majoring in chemistry. / Her major is chemistry.
表達主修某個學科時，正確的動詞片語是「major in」。不能直接用「is major in」。
