must do sth 还是 must to do sth

must do sth 还是 must to do sth
Must如果当助动词用,后方加的是不带TO的不定式.
Must do sth.
如果用作名词,句型就不是这样写,应该是:
It's a must to do sth.
Promptness on the job is a must.Comfortable shoes are a must when taking a walking tour of Wales.
工作上准时是绝对必要的.步行去威尔士旅行时舒服的鞋是绝对必要的物品
n.attributive.(定语名词)
Often used to modify another noun:
常用来修饰另一个名词:
a new book that is must reading; a list of must legislation for the session.
一本不可不读的新书;开庭不可缺少的立法一览表

must 后面只能加动词原形,所以应该是must do sth.

must do sth
情态动词 must 后用动词原形
