drill

Compared meaning: to make a hole (verb).

比较义项：钻孔、打洞（动词）。

• drill 本词

  Drill specifically means to use a rotating pointed tool to make a hole; it is the everyday word for small, precise holes in wood, metal, teeth, and similar materials.

  drill特指用旋转的尖头工具打孔，是日常用语，多用于在木头、金属、牙齿等材料上钻出较小而精确的孔。

  The carpenter drilled several holes before inserting the screws.

  木匠在拧入螺丝之前，先钻了好几个孔。

• bore

  Bore is a more general or technical word for cutting through material to make a hole, often used for larger or deeper holes such as a tunnel or a well, without implying a drill.

  bore是更笼统或更专业的说法，指切除材料以形成孔洞，常用于较大或较深的孔（如隧道、水井），不一定使用钻头。

  Workers bored a tunnel through the mountain for the new railway.

  工人们为修建新铁路，在山中钻凿出一条隧道。

Drill and bore both mean to make a hole. Drill means using a rotating tool for small, precise holes. Bore is more formal, for larger or deeper holes, like a tunnel or well. Bore's 'tedious' and drill's 'training' meanings are not compared.

这两个词在“钻孔”这一意义上相近，但语域和用法不同：drill是日常用词，强调用钻头等工具打孔；bore更正式、技术性更强，常指去除材料形成较大或较深的孔（如隧道、水井）。这里不比较bore的“使人厌烦”之义，也不比较drill的“操练、训练”之义。

Compared meaning: repeated practice to master a skill (verb).

比较义项：反复练习以掌握技能（动词）。

• practice

  The most general, everyday word for repeating an activity to get better at it; used for almost any skill (language, sport, music) and works for both self-directed and instructor-led practice.

  这是表示为提高技能而反复做某事的最通用、最常见的词，几乎可用于任何技能（语言、体育、音乐），既可以是自主练习，也可以是有老师指导的练习。

  You should practice speaking English every single day.

  你应该每天都练习说英语。

• exercise

  Rarer and more formal than practice; it emphasizes actively using or applying a skill or mental faculty (memory, vocabulary, judgment) rather than mechanical repetition.

  比practice更少见、更正式，强调主动运用或发挥某种技能或能力（记忆力、词汇量、判断力），而不是机械地反复操作。

  You can exercise your listening skills by watching movies without subtitles.

  你可以通过看没有字幕的电影来练习你的听力技能。

• drill 本词

  Implies structured, often teacher-led or mechanical repetition; it can take a person as its object ('drill students in grammar'), suggesting imposed, rote training rather than self-directed practice.

  强调有结构、通常由老师主导或带有机械性质的反复操练；可以以人作宾语（如“drill students in grammar”训练学生语法），带有被动接受、反复操练的意味，而不是自主练习。

  The teacher drilled the students on irregular verbs every morning.

  老师每天早上反复训练学生掌握不规则动词。

Practice, exercise, and drill mean repeating something to master a skill. Practice is the most common, for any skill, alone or with a teacher. Exercise is rarer and more formal, meaning to use a skill you have. Drill means teacher-led, mechanical repetition.

这三个词都可以表示为掌握某项技能而反复练习或训练，但语气和用法不同：practice最常用、最口语化，exercise更正式、强调运用已有能力，drill则强调由老师主导或带机械性质的反复操练。这里不比较exercise表示“体育锻炼”（如例句中的健身义）或作名词的用法，也不比较drill表示“钻头、钻孔”的工具义，也不比较practice表示“惯例、习惯”或律师、医生“执业”的用法。
