Prep part1 37 (关于否定句中or 和 nor的用法)

holddreams

One report concludes that many schools do not have, or likely to have, enough computers to use them effectively.
(A) or
(B) nor
(C) or are
(D) nor are they
(E) nor are not

答案是d 但是c中not ..or也同样表达不是而是地意思，they被省略可以理解成因为和主句主语一样，但为什么不选c呢

many schools do not have, or are likely to have, enough computers to use ...

 

这个句子里面 or are likely to have 和 do not have 并列阿 意思就不对了 少了一个否定词

同问。我的疑问是为什么不选A呢？

楼主问的or 跟nor这个问题我也等待高人回答。

至於are的部分，
One report concludes that many schools do not have, or likely(adv) to have

由於likely是adv，代表or省了subject跟verb，往前找看省了什麽？
many schools(subject) do not have(verb) likely(adv) to have
这样句子怪怪

且 be likely to 是习惯用法。

或许否定句中or用法是用於名词类，至於动词类可能是另一条规则。

Please correct me if i am wrong.

既然楼上已经说到了be likely to是习惯用法，那么are必须要出现，所以只能在C,D,E中选。

另外，nor的意思是“也不”。如果两个谓语动词一致，那么可用not...or...， 如果不一致，需要在第二个动词处用nor。所以在D，E中间选。而E中，nor与not重复，错。
