consider

Compared meaning: to use your mind to think about something (verb).

比较义项：用心智考虑某事（动词）。

• think

  The plainest, most everyday word for using your mind on something; it does not suggest special care, depth or length of time.

  最普通、最日常的用词，只是笼统地动脑筋想一想，没有特别强调认真、深入或耗时长。

  I think it will rain later this afternoon.

  我想今天下午晚些时候会下雨。

• consider 本词

  Suggests weighing something carefully and deliberately, often before making a decision; more formal than think and implies a purposeful process.

  强调认真、有目的地权衡某事，通常是在做决定之前；比 think 更正式，暗示一个有目的的过程。

  You should consider all your options before making a decision.

  你在做决定之前应该考虑所有的选择。

• ponder

  Implies thinking deeply and for a long time, often about a difficult or serious matter, with a quiet, reflective or worried tone; formal or literary.

  暗示长时间、深入地思考，通常是关于困难或严肃的事情，带有安静、沉思甚至忧虑的语气；用词正式或偏文学化。

  He sat quietly, pondering whether to accept the new job.

  他静静地坐着，沉思着是否要接受这份新工作。

Think, consider and ponder all mean using your mind on something, but tone differs. Think is the plainest, everyday word. Consider means weighing something carefully, more formal than think. Ponder means thinking deeply and long. Think can mean 'believe'; consider can mean 'regard'; not compared.

这三个词在“动脑筋考虑某事”这个意义上相近，但语气强弱和正式程度不同：think 最普通，只是笼统地想一想；consider 强调认真、有目的地权衡；ponder 强调长时间、深入地沉思，语气更正式、更书面。这里不比较 think 表示“认为，相信”的意思，也不比较 consider 表示“认为…是，把…看作”的意思。

Compared meaning: to judge that something is true (verb).

比较义项：认为、判断（某事属实）（动词）。

• think

  The everyday, informal way to state an opinion; naturally followed by a clause, with no extra grammatical structure needed.

  日常口语中表达看法最常用的说法，后面自然接从句说明想法，不需要特殊结构。

  I think we should leave soon, or we'll be stuck in traffic.

  我觉得我们该早点出发，不然会堵在路上。

• consider 本词

  More formal; typically takes a direct object followed by a complement, suggesting a judgment reached after some thought rather than a casual opinion.

  更为正式，通常直接接宾语和补语，强调经过一番思考后得出的判断，而不是随口说出的看法。

  The committee considers him fully qualified for the job.

  委员会认为他完全胜任这份工作。

Think and consider both mean to judge that something is true, but structure differs. Think is informal, usually followed by a clause. Consider is more formal, taking a direct object, suggesting judgment after thought. Think can mean 'ponder a problem'; consider can mean 'weigh choices'.

这两个词在“认为某事属实”这一义项上意思相近，但语气和结构不同：think 是日常口语里最常用的说法，后面常接从句说明想法；consider 更正式，常直接接宾语和补语来表达经过考虑后的判断。这里不比较 think 表示“思考、琢磨某个问题”以及 consider 表示“考虑、权衡各种选择”的用法。
