陷阱
⚠️concentrate on（介词 on）——× concentrate at / × concentrate to
To perform well in an examination, students must concentrate on the question being asked rather than writing everything they know about the topic.
✗
× concentrate at the question / × concentrate to the question
✓
concentrate on sth.（专注于某事，固定介词 on）；× concentrate at / concentrate to 均不正确；对比：focus on = 同样用 on；put one's mind to = 用 to（× concentrate to）
为了在考试中表现出色，学生必须专注于所问的问题，而不是写出他们所知道的关于该话题的一切。（concentrate on，× concentrate at/to）
⚠️concentration（专注）vs. concentration（浓度）——同一词，两种含义
✗
The scientist measured the concentration of students in the classroom to determine how focused they were.
科学家测量了学生的专注程度，以确定他们的注意力有多集中。（concentration 两义：专注/浓度——此句混用）
concentration 有两个独立义项：① 专注力（powers of concentration = 专注力；lack of concentration = 注意力不集中）；② 浓度/密集度（a high concentration of pollutants = 高浓度污染物；concentration of CO₂ = CO₂浓度）；此句 concentration of students（学生的密度/集中度）= 有多少学生集中在某处，但 to determine how focused they were 说的是注意力，语义混乱；若要说「测量学生专注度」，用 levels of concentration
✓
The researcher measured the concentration of carbon dioxide in the air sample taken from the urban traffic zone.
研究人员测量了从城市交通区采集的空气样本中二氧化碳的浓度。（concentration = 浓度，此义项正确）
近义辨析
concentrate vs focus
concentrate concentrate (on)（专注于：concentrate on the task = 专注于任务；强调将所有注意力汇聚于一点） focus focus (on)（关注，聚焦：focus on the key issues = 聚焦关键问题；比 concentrate 更广泛，也可指方向性关注而不只是高强度专注）

concentrate investment in（将投资集中于某处）用法正确；rather than + 动名词 spreading = 正确对比结构；too thinly = 副词修饰，语法正确
Q2近义选词
选择最恰当的词填空：
The report recommends that future research should ___ on the long-term health impacts of air pollution rather than immediate symptoms.
Aconcentrate
Bfocus
✓ 报告建议未来的研究应聚焦于空气污染的长期健康影响，而不仅仅是即时症状。
focus on（聚焦于）更适合研究方向性语境；concentrate on 通常指个人高强度专注；research should focus on = 研究方向应指向，是学术写作标准表达
