没完全看懂后半句的意思,因为你没给出例句.
so that 结构的复合句的有关从句是状语从句：
1.so that
We held a meeting so that we might discuss the matter thoruthly.
We worked fast and well,so that we overfulfilled our production plan.
His father died so that no one supported his living.
2.so ……that
The little girl was so poor that she could not afford to buy a pair of shoes for herself.
He runs so fast that he wins the race.
在上面的句子中,“that”都是不能省掉的.
好象都没有与宾语从句扯上什么关系,虽然句中还可能会有宾语从句.
