require of A to do到底对不对？－og109和181的矛盾

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.

(A)     that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are

(B)      that pay for jobs historically held by women should be the same as for a job requiring comparable skills

(C)     to pay the same in jobs historically held by
    women as in jobs of comparable skill that are

(D)     to pay the same regardless of whether a job was
    historically held by women or is one demanding
    comparable skills （A）

(E)      to pay as much for jobs historically held by women
    as for a job demanding comparable skills

Choice A is best. In choice B, should is illogical after requires, or at least unnecessary, and so is better omitted; in choices B and E, job does not agree in number with jobs（尤其要注意，在并列中，单复数也要对应，一致）
    ; and in choices B, D, and E, the wording illogically describes the comparable skills rather than the jobs as being "usually held by men." （用定语从句多重修饰就没问题）Choices C, D, and E produce the ungrammatical construction requires of... employers to pay, in which of makes the phrase incorrect. In C, the use of in rather than for is unidiomatic, and jobs of comparable skill confusedly suggests that the jobs rather than the workers possess the skills(仔细体会表大意思的细微差别，这大概就是所谓的语感吧). In D, the phrase beginning regardless ... is awkward and wordy in addition to being illogical.

Require somebody to do sth

分词和定语从句的多重修饰！

Require of somebody that…

181. Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.

(A)             to survive

(B)              of firms to survive

(C)             for surviving

(D)             for survival （B）

(E)              for firms' survival

The subject of the main clause (such firms) presumes a prior reference to the firms in question. Furthermore, the logical subject of to survive and the logical complement of required should be made explicit. All three demands are met by B, the best choice. Choices A, C, and D, with no reference to the firms in question, meet none of these demands. In choice E, the illogical and awkward use of a prepositional phrase (for firms' survival)—这个结构本身就很笨拙
    buries the needed initial reference to firms in a possessive modifier.------很重要，用所有格以后，后面的such firm 就没有指代对象了

这道题中的require of A to do 就是正确的，但是103怎么就说没有这种结构呢？这种结构到底是不是正确的呢？

up~

没有看出被动语态啊,是说require sth of to do是可以的，而require sb to do就不行了么？

说第二个

because　ｏｆ　后面只能是名词成分，　　

１　required　ｔｏ　ｓｕｒｖｉｖｅ　可以看成前面的后置定语

　　拆开看　required　本身做过去分词非谓语，后面to survive 做REQUIRED的补语

2      因为我们要把OF FIRM这个定语加进去（后面such的限制）

       最佳位置就在required后面，不然有歧义

所以两个不一样

第一个是 required that 。。。 它把PAY后面 OF 的定语提前了。

所以根本就没有 required OF N 这种结构 

哦~~一语惊醒梦中人,还是对句子的理解不够啊..谢谢jbyupei

我觉得是 require sth of sb..这个词组。   第一句中 that 修饰 sth， 所以是 require of sb that...

第二个是 这个词组的被动... sth be required of sb    to do 是require 的补语
