so as to 和so that

OG 11原题：

In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled so as to marry Anne Boleyn.

A) so as to marry

B) and so could be married to

C) to be married to

D) so that he could marry

E) in order that he would marry

OG说A错给的解释是：so as to marry is not idiomatically correct; it does not identify who will marry

不过我查了一下，很多句子都直接用 so as to do something表示目的di

e.g.: he observed the snakes so as to describe their behavior。

有些糊涂了，向NN请教。

一般我们看到的so as to例句都是只有1个动作对象的。

(you)Go in quietly so as not to wake the baby.
(you)Go in quietly in order that you will not wake the baby.

Tom kept quiet about the accident so as not to lose his job.
Tom kept quiet about the accident in order that he would not lose his job.

这里的句子是

In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled so as to marry Anne Boleyn.
In 1527 King Henry VIII sought to have his merriage to Queen Catherine annulled in order that (  ) would marry Ann Boleyn.

这里的blank中可以填King Henry VIII，也可以填Queen Catherine。这样，与GMAT严谨细致的风格就不符合了。

找到一句例句。

大全219：

Congress is debating a bill requiring certain employers provide workers with unpaid leave so as to care for sick or newborn children.

(A) provide workers with unpaid leave so as to
(B) to provide workers with unpaid leave so as to
(C) provide workers with unpaid leave in order that they
(D) to provide workers with unpaid leave so that they can（D）
(E) provide workers with unpaid leave and

可见so as to 在表现人物动作关系方面没有so that强大。
