句式剖析

We wish to change the SLA and include a provision for an agency representative to review all your works before it is sent for uploading on our website.

to review all your works修饰 an agency represnetative做目的状语

介词for这里表示什么？

那样for an agency representative to review all your works修饰 a provision做句子的什么成份呢？

before it is sent for uploading on our website.修饰works是看作时间状语吗？

for an agency representative to review all your works before it is sent for uploading on our website

这是不定式复合结构for sb to do sth. 作include a provision的目的状语。其中before从句是不定式的时间状语，是不定式复合结构的一部分。
