need

2 used to show what you should or have to do.用来表示你必须要做的事eg:All you need to do is complete this form.
want

2 to lack sth 缺少什么东西,这个例子就不举啦.
require
1 to need sth; to depend on sb/sth注意是depend.eg:These pets require a lot of care and attention.
2 常被动语态.sth (of sb) to make sb do or have sth,especially because it is necessary according to a particular law or set of rules注意后面的particular law or set of rules
eg：All candidates will be required to take a short test.
有不明白的再追加问题~我基本都在线的
require sb to do True marriage requires us to show trust and loyalty
require that The situation required that he be present
require doing Lentils do not require soaking before cooking
require sb of sth常被动 What exactly is required of a receptionist
want to do eg:It’s time you did your homework.’ ‘I don’t want to!’
want sb to do eg:Do you want me to help
want doing eg:I don’t want you coming home so late.
want还可以直接接宾语
need to do eg:I need to get some sleep
need doing/to be done eg:This shirt needs washing.This shirt needs to be washed
need也可以直接接宾语
然后结合我上面说的跟语境判断用哪一个.
