GMAT:OG一道SC实在是没懂,
In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled _________ Anne Boleyn.
a.so as to (原文就是so as to,不好区别划线部分所以提出来）
b.and so could he married to
c.to be married to
d.so that he could marry
e.in order that he would marry
e12,p704其实有解答.我选的A,因为我觉得so as to marry可以用,平常说话也经常用到“do...,so as to do..."的句型呀,为什么解答里面说"so as to marry is not idiomatically correct; it does not identify who will marry."可是我觉得这个很明显,是King Henrry VIII要marry,没有其他主语了,这是一个单句呀.
请高手释惑.
所以一楼你的意思是，如果按照parallel理解，应该是：so as to have Anne Boleyn married?
那么相比之下d比较简洁。
