hit

Compared meaning: to hit something with force (verb).

比较义项：用力击打或撞击某物（动词）。

• knock

  Knock refers to a light, often repeated tapping action, typically with the knuckles or a small object against a surface, not a single hard blow.

  knock表示轻轻地、通常反复地敲击，比如用指关节敲门，而不是一次用力的重击。

  He knocked gently on the window to get her attention.

  他轻轻敲了敲窗户，想引起她的注意。

• strike

  Strike implies a sudden, forceful, often unexpected blow, and is the natural word for attacks by animals, weapons, or natural forces, sounding more dramatic than hit.

  strike强调突然、猛烈、常常出人意料的一击，常用于动物、武器或自然力量的攻击，语气比hit更强烈、更具戏剧性。

  The snake struck without warning, sinking its fangs into his leg.

  那条蛇毫无预兆地猛地一击，将毒牙咬进了他的腿里。

• hit 本词

  Hit is the most common, neutral, everyday word for physical contact with force, used for accidents, sports, and casual roughhousing alike, without strike's formality or knock's lightness.

  hit是最常见、最中性的日常用词，指用力接触某物，适用于事故、体育运动或一般的打闹场景，不像strike那样正式，也不像knock那样轻。

  The boy accidentally hit his sister with the ball while playing catch.

  男孩在玩接球游戏时，不小心用球打到了他妹妹。

Hit, strike, and knock all mean to hit something. Knock is a light, repeated tap, often with the knuckles. Strike is a sudden, forceful, dramatic blow, as from an attack. Hit is the common, neutral word for force. Knock can mean to criticize; not compared.

这三个词都表示「击打」，但用力方式和语境不同：hit最通用，strike更用力、更突然或更正式，knock指用拳头或物体轻敲表面。这里不比较strike的「罢工」义、knock的「批评」义，以及hit的「命中」「走红」义。

Compared meaning: to arrive at a place or level (verb).

比较义项：到达（某处、某数值或某阶段）（动词）。

• reach

  Neutral, general verb for arriving at a place, level or result, often after effort or distance; also covers physically extending or stretching to touch something.

  中性、通用的动词，指经过努力或距离到达某个地方、水平或结果；也可指身体伸展去够到某物。

  You need to stand on a chair to reach the top shelf.

  你需要站在椅子上才能够到最上面的搁板。

• hit 本词

  Informal, conversational verb often used when someone suddenly arrives at a number, milestone or low point; carries a sense of impact or surprise, and is not used for physical extension.

  口语化、较随意的动词，常用于突然达到某个数值、里程碑或低谷，带有冲击感或意外感，不用于表示身体延伸够到某物。

  After losing his job, he felt like he had hit rock bottom.

  失业之后，他感觉自己跌到了人生谷底。

Reach and hit both mean to arrive at a place, number, or level. Reach is neutral and formal, often after distance or effort. Hit is informal, suggesting a sudden arrival at a number or a low point. Hit meaning to strike something is not compared.

reach 和 hit 在表示“到达”时意思相近，但 reach 语气中性、书面，强调经过距离或努力到达某处、某数值，也可指身体延伸够到某物；hit 语气更口语化，强调突然到达某个数值、阶段或低谷，带有一点意外或戏剧性的意味。这里不比较 hit 表示“撞击、打中”的意思，例如 the ball hit the window and broke the glass 中的用法。

Compared meaning: a hard, forceful blow (noun).

比较义项：一次用力的打击（名词）。

• strike

  A forceful, deliberate blow, often used in formal, sporting, or violent contexts such as boxing or military attacks; more formal in tone than hit.

  指强烈、蓄意的一击，常用于正式、体育或暴力语境，例如拳击或军事打击；语气比hit更正式。

  The champion landed a powerful strike to his opponent's jaw in the final round.

  冠军在最后一回合给了对手下巴一记有力的strike。

• hit 本词

  The plain, everyday word for an act of striking something; neutral in tone and used for accidental or ordinary contact, not limited to sports.

  是表示打击动作最普通、日常的词，语气中性，常用于意外或普通的碰撞，不限于体育场景。

  A hit on the head from a falling branch left him dizzy.

  一根掉落的树枝hit了他的头，让他感到头晕。

• smash

  A powerful overhead shot in racket sports like tennis or badminton, struck hard to win the point; not used for ordinary or violent blows.

  指网球、羽毛球等球拍类运动中用力扣杀得分的高压球，不用于日常或暴力性的打击。

  Her smash flew past the net and landed just inside the line.

  她的smash飞过球网，正好落在界内。

Strike, hit, and smash all mean a forceful blow. Strike is formal, used in sports, military, or violent contexts. Hit is the plain, everyday, neutral word. Smash means a powerful overhead shot in tennis or badminton. Other meanings of these words are not compared here.

这三个词都可以表示“用力打击”的动作，但语气和使用场合不同：strike较正式，常见于体育、军事或暴力语境；hit最常用、最中性；smash则专指网球、羽毛球等运动中用力扣杀的高压球。这里不比较strike的“罢工”义、hit的“热门作品”义，以及smash的“猛力打碎”义。
