同时告诉我
It's important ( ) the boy to learn a foreign language.
English is important ( ) the boy because he wants to go abroad.
各用for of to的哪个,为什么,理由,
比如说:什么是用于什么的

It's for sb.和 It's of sb.

1)for sb. 常用于表示事物的特征特点,表示客观形式的形容词,如easy, hard, difficult, interesting, impossible等:
It's very hard for him to study two languages. 对他来说学两门外语是很难的。
2)of sb的句型一般用表示人物的性格,品德,表示主观感情或态度的形容词,如good, kind, nice, clever, foolish, right。
It's very nice of you to help me. 你来帮助我,你真是太好了。

for 与of 的辨别方法:
用介词后面的代词作主语,用介词前边的形容词作表语,造个句子。如果道理上通顺用of,不通则用for。如:
You are nice. (通顺,所以应用of)。
He is hard. (人是困难的,不通,因此应用for。)

这些知道就可以了吧~to应该不太难搞吧

1. for
for sb to do sth

2. to
be important to sb
