50. That educators have not anticipated the impact of microcomputer technology can hardly be said that it is their fault: Alvin Toffler, one of the most prominent students of the future, did not even mention microcomputers in Future Shock, published in 1970.

(A)         That educators have not anticipated the impact of microcomputer technology can hardly be said that it is their fault

(B)         That educators have not anticipated the impact of microcomputer technology can hardly be said to be at fault

(C)        It can hardly be said that it is the fault of educators who have not anticipated the impact of microcomputer technology

(D)        It can hardly be said that educators are at fault for not anticipating the impact of microcomputer technology

           (E)The fact that educators are at fault for not anticipating the impact of microcomputer technology can hardly be said

请问是否可以这样总结: 主语从句加被动往往错？

根据OG解释，a的主要错误在于主语从句中又套了一个从句,打乱了正常的语序.而b中

主要是can hardly be said to be at fault 很难在语法上完成这一从句.我们可以简化

下看,就变成That...(这件事) be at fault.在正确句子里我们发现是educators(人)be

at fault.所以在这里指事是不合语法的.

主动大于被动的前提是主动在语法上都没有错误,且动作发起者和接受者都是明确的.若

主语从句中出现只能用无明确动作接受者的被动语态,并不能很肯定地说是错误的.
