大全219

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

我知道so as to 和so that是区分是否是单一逻辑主语的，我的问题是主语是指哪个，比如这题：如果用了so as to，主语是指向了Congress还是employer呢？

两个考点:

1.require that & require to的区别,没有问题;

2.清晰指代:其实OG里有几乎是一样的原题,用OG的口气解释B错是ambiguous,so as to会混淆是指向employers还是workers,所以楼主的sense非常棒

关于D项我还有一个疑问:

so that they can的they有没有指代不明的问题? 因为they既可以指workers, 也可以指employers.
