解釋 need to be 同 need to 既分別

NEED TO

need to do something

If you need to do something, it is necessary for you to do it.
Need is followed by infinitive with “to”
to 後面是 bare infinitive; That is a verb (base form)
For example, 用 “do”, 不是 does, doing, did, done.

You need to do your homework.

除此之外,

Need to be + adjective
