为什么og181和og109对require of..to do对错解释不同?

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

(E) for firms’ survival

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         

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

为什么这两题对require of .....to do的解释不同

109说这个词组错,当然C,D,E错还有其它错误.

181就认为对.

请高手指点

my two cents:

in 181, "expenditure" is the actual requirement "required". In 109, "Legislation" is the subject of "require".

In other word,

sth (the actual requirement) required of sb to do ...  correct

sb requires of sb that ...   correct

sb requires of sb to do ......  incorrect

good catch, I didn't realize there is such a subtle difference in using "require of" and "require that"

thanks a lot.

My personal opinion is that in 181  "of firms " is used to modify the "research and development expenditures" instead of being used with "require" to form a verb.

我也发现了这个问题，这个总结可以记住吗？我的意思是，它一定是对的吗？

一点总结:

Sth require that sth (should)be do 

sb require sb to do         

sb is required to do sth  被动

sth require of sb that sth (should)be   

sth required of sb to do   被动
