We need a lot of energy to study every day .
本句可改成：
In order to study every day,we need a lot of energy.所以,是目的状语.
I get the boy to study every day.
In order to study every day,I get the boy.就不对了,意思不对的.
怎么区分动词不定式作目的状语还是宾补
宾补：其实就是宾语的意思上的谓语呢.
也就是说：宾语和宾补是意思上的主谓关系.把宾语和宾补拿出来,可以组成一个新句子的.
I get the boy to study every day:
宾语和宾补成句：、
The boy studies every day.
He made me happy.
宾语和宾补成句：
I was happy.
I think it right.
宾语和宾补成句：
It is right.
