常見錯誤
What are common mistakes with "Concentration"?Which "Concentration" sentences look correct but are wrong?
×I need a high concentration to study.
✓I need a high level of concentration to study.
「concentration」本身是一個抽象名詞，表示「專注」的狀態或能力，而不是一個可以「擁有」的具體物品。通常會說「a high level of concentration」或「great concentration」。
×He lost his concentration during the meeting.
✓He lost concentration during the meeting.
「concentration」在這裡是一個不可數的抽象概念，通常不加所有格代名詞「his」。正確用法是「lose concentration」或「lose one's focus」。
×The concentration of students in the library is high.
✓The number of students in the library is high. / There is a high concentration of students in the library.
「concentration」用於描述事物在特定區域的「密集度」或「集中度」，而非單純的「數量」。若要表達數量多，應使用「number」。若要表達在特定區域內密集聚集，則可使用「concentration of」。
×She has a good concentration on her work.
✓She concentrates well on her work. / She has good concentration when working.
「concentration」是名詞，不直接與「on」連用構成「concentration on」。正確的動詞搭配是「concentrate on」。若要用名詞，可以說「her concentration is on her work」或「she has good concentration」。
×I can't keep my concentration for long times.
✓I can't maintain concentration for long periods.
「for long times」不是地道的英語表達。應使用「for long periods」或「for a long time」。同時，「keep concentration」不如「maintain concentration」或「sustain concentration」正式和常見。
×The chemical has a 50% concentration.
✓The chemical has a concentration of 50%. / It is a 50% concentration solution.
表達濃度百分比時，通常使用「a concentration of X%」的結構，或者將百分比作為形容詞放在前面，如「a 50% solution」。直接說「has a 50% concentration」聽起來不自然。
