几个语法点请教！[求助]

关于require of sb to do
OG 181
Because of the enormous research and development expenditures required (of firms to survive) in the electronic industry, an industry marked by rapid innovation and vilatile demand, such firms tend to be very large.

109
Legislation in the Canadian province of Ontario requires of both public and private employers (that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are usually held by men.)
其中该题选项中出现了
require of both public and private employers to pay……OG中的解释说到其中的require of sb 的of不对。

我想问的是到底有没有这样的用法呢？如果没有，那么前一题的of又怎么解释呢？



关于which的指代
OG164  The commission proposed that funding for development of the park, (which could be open to the public next year, be )obtained theough a local bond business.

这题的E选项为development funding for the park, which could be open to the public early next year……OG的解释中说这个选项里的which指代的是development funding而不是park所以它是错的。我想问的是为什么在which前面明明就是park，而说他指代的是development funding，而正确答案中的却指的是park。是不是因为介词的区别呢？


还有一个问题就是关于分词的修饰对项：我的理解是如果分词被，隔开，那么它应该修饰的是句子的主语，若没有隔开则修饰的是紧跟着在前的名词，可是在看OG的时候却常常碰到一些让我迷惑的解释。不知道有没有nn能告诉我我的这个理解对不对？或者说应该怎么去判断分词的修饰对项呢？尤其是当他被，隔开时。谢谢！

另外还有的就是关于if句型的时态问题，有时候会在OG上看到 if x do, y do 而不是我们通常要求的 if x do, y will do。我可不可以理解为 如果有符合后者的应选后者，而没有的话只能选择一个较好的？
