請問This is the rules for we have to follow for school.句中for文法解釋?

These are the rules for us to follow at school.
原句可能改寫成上面這樣才通順。

for us是修飾前面名詞rules的「介系詞片語」。

第一個for 當連接詞意指原因，而第二個 for當介詞，為了-----目的

This is the rule-------s+v
------or These are the rules(Plural no)
(which=pronoun,shows what rules are meant) we have to follow--------adj.cl.of reason, manner,condition,purpose to qualify rule 
---(no "for" the prep here.)
for school;-----o---->for=prep,meant to be given to,,used by, used in students in school.

.......................................for you，為你而設

所指的意思是 去 或是 到達的意思。

兩個for都是介系詞第一個可以改為which/that，其實並沒有意思哦，相當於一些古文中的無意例如（斯）
