• excited

  The everyday, general word for feeling eager and happy about something; moderate in strength, used constantly in casual speech, and pairs naturally with 'about' or 'to' + verb.

• thrilled 本词

  A stronger, more emphatic word than excited, describing intense, almost overwhelming happiness at unexpected or very good news; often used in the fixed phrase 'thrilled to bits', which does not work with 'excited'.

  这个词比excited语气更强，形容因意外或特别好的消息而感到强烈到近乎难以抑制的高兴；常出现在固定搭配thrilled to bits中，这个搭配不能换成excited。

  He was thrilled to bits when he found out he'd won the lottery.

  他得知自己中了彩票时高兴得不得了。

Excited and thrilled both describe feeling happy and eager about something, but they differ in strength. Excited is the common, everyday word, showing moderate eagerness. Thrilled is stronger, describing intense happiness at unexpected or very good news, as in 'thrilled to bits'.

这两个词都表示对某件事感到高兴、兴奋，但程度不同：excited是最常用的日常用词，程度适中；thrilled语气更强，强调因意外或特别好的消息而感到极度兴奋，常见于thrilled to bits这类固定搭配中。两词的义项范围都只限于这一种含义，此处不涉及其他义项。
