• snap 本词

  Snap means the object breaks suddenly and completely, usually into two pieces, with a short sharp sound; it happens instantly and suits thin, brittle or rigid things like branches or pencils.

  snap指物体突然、彻底地断裂，通常断成两截，并伴随一声清脆的响声；这个过程是瞬间发生的，常用于树枝、铅笔等细长而脆的东西。

  她踩到那根干树枝时，树枝“啪”的一声断成了两截。

Both mean an object breaks, but differently. Crack means a fissure appears on the surface, usually staying in one piece, common for glass or bones. Snap means it breaks suddenly and completely into two pieces, with a sharp sound. Other senses are not compared here.

这两个词都表示物体“断裂”，但crack强调物体表面出现裂纹而通常仍连在一起，snap强调突然发出清脆响声、彻底断成两截。这里不比较crack的“讲笑话”“破解密码”等义项，也不比较snap的“拍照”“突然发火”等义项。

  "Get out of my way," he snarled, gripping the knife tighter.

Both mean speaking angrily, but with different force. Snap suggests a short, sharp, irritable reply, from impatience rather than real threat. Snarl suggests a low, growling, menacing tone, like an animal baring its teeth. Snap's other meaning, breaking suddenly, is not compared here.

这两个词都表示以严厉、愤怒的语气说话，但语气强度和联想不同：snap更强调说话简短、尖刻、不耐烦；snarl则带有低吼般的凶狠语气，让人联想到动物的咆哮。这里不比较snap“啪地折断”等其他含义。
