求英语高手帮忙分析下句子结构26

首先ABC不是句子的主谓宾，ABC只是that引导的同位语从句的主谓宾。句子没有主语，因为句子是祈使句！see to it.确保它、that是it的同位语从句。whatever引导的是宾语从句，做inlucde的宾语。所以DEF修饰的是include。howto answer是know的宾语。
把句子顺序调好如下：
See to it that you include whatever questions they didn't know how to answer last week in the the examination paper.
希望能帮到你。

注意将他们上次不知道如何作答的问题都归纳到考试卷上。
see to it是整个句子的主句，启使句。it是形式宾语，that引导的后面的全部是实际宾语，也就是宾语从句。而这个实际宾语本身又包含一个定语从句：you include in the examination paper whatever questions是小主句，they didn't know how to answer last time是 whatever questions的定语从句。E中how to answer是D中they didn't know的宾语从句。F中的last time只是最后一个定语从句的时间状语，并不是从句。whatever等中带的ever都等于no matter.
