• easily 本词

  The standard, general-purpose adverb; freely combines with almost any verb and is natural in both formal and casual writing.

  标准的通用副词，几乎可以自由搭配各种动词，正式或口语语体中都很自然。

  She easily lifted the heavy box without any help.

  她毫不费力地就搬起了那个沉重的箱子，没有借助任何帮助。

• easy

  An informal adverb limited to fixed expressions and casual speech, such as take it easy, go easy, or win easy; it cannot freely modify ordinary verbs the way easily does.

  口语化副词，仅用于固定搭配和随意口语中，例如 take it easy、go easy、win easy，不能像 easily 那样自由修饰普通动词。

  Go easy on the salt — the soup is already salty enough.

  盐少放一点——汤已经够咸了。

Both mean 'without effort'. Easily is the standard adverb, combining freely with almost any verb. Easy as an adverb is informal, limited to fixed phrases like 'take it easy' or 'go easy'; it cannot modify other verbs freely. Not covered: easy meaning 'not difficult'.

这两个词都表示毫不费力地，但 easily 是标准副词，可以自由修饰几乎任何动词，书面语和口语都能用；easy 用作副词是口语用法，只出现在少数固定搭配中，例如 take it easy、go easy、win easy，不能像 easily 那样自由搭配其他动词。这里不比较 easy 作形容词表示容易的这一义项。
