[✌形容词前有too时，a/an要置于形容词之后、名词之前，类似位置的词还有as, so, how]

音组-oo/-uː/

too; zoo

同音 to; too; two

常犯错误

I'm only too glad to join you. 译为：

✗ 我太高兴了而不加入你们。

✓ 我很乐意加入你们。

用法only too和all too为固定用法，都是very的意思，所以only too/all too ... to do sth 并不表示否定概念，而是肯定概念。某些表达心情的形容词放在too ... to do sth结构时，就是too前面没有only，也表示肯定的含义。如：too ready/willing to do sth意为“很乐意/很愿意做某事”。

谚语It's never too old to learn. 活到老，学到老。

辨析also; too; as well
