谁知道单词use，used的用法

Question

谁知道单词use，used的用法，短语之类的，
例如：used to do sth. 过去做某事

Answer 1

use是动词原形，也可以作名词
used是过去时或者过去分词，也可以作形容词
used to / be used to

used to + do："过去常常"表示过去习惯性的动作或状态，但如今已不存在。
Mother used not to be so forgetful.
Scarf used to take a walk. (过去常常散步)

be used to + doing： 对……已感到习惯，或"习惯于"，to是介词，后需加名词或动名词。

Scarf is used to taking a walk.(现在习惯于散步)

典型例题
---- Your phone number again? I ___ quite catch it.
---- It's 69568442.
