題目：

這三個詞在語法上有什麼特點
need want require
詳細的加送50分 最好有例句
在後面接的詞上有什麼要求嗎?

解答：

need
1 to require sth/sb because they are essential or very important,not just because you would like to have them.就是說需要的人或物是必須的或者很重要的.eg:What do you need your own computer for?You can use ours
2 used to show what you should or have to do.用來表示你必須要做的事eg:All you need to do is complete this form.
want
1 to have a desire or a wish for sth 有主觀願望在裡面 eg：She’s always wanted a large family
2 to lack sth 缺少什麼東西,這個例子就不舉啦.
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 常被動語態.sth (of sb) to make sb do or have sth,especially because it is necessary according to a particular law or set of rules注意後面的particular law or set of rules
eg：All candidates will be required to take a short test.
有不明白的再追加問題~我基本都在線的
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常被動 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還可以直接接賓語
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也可以直接接賓語
然後結合我上面說的跟語境判斷用哪一個.
