标题: 求指教！！！旧PREp 的37题。。。nor的单独用法。。。
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，是正确答案。。。。
(E) nor are not
但是，为什么nor 不对。。。并且我一开始选了or are.....请问怎么做这道题。。。

首先根据前面do not have判断句意为否定，排除AC（E也可以在此时排除，因为用双重否定，而且表达awkward）
然后nor前面的谓语动词是do，而后面be likely to have的结构需要一个be，因此该系动词不能省略，需要补出系动词和其主语。

好晕呀~~还是不明白这个or和nor到底是什么区别呀，or也可以表示否定呀，He cannot read or write.
哪位NN能够帮忙解答下？？谢谢

darkbaby给出的例句里read和write是两个平行的动词，所以被前面的cannot引领否定，并不是or表示否定~
比如在本题中do not have，后面如果是一个同have平行的动词，就无需再否定了比如
I do not have or like banana（谎话！我最喜欢了！）
而本题中的平行对象则是do not have中的do，因此需要用nor表示否定

(a) and (b) are incorrect because of their poor parallelism. in this "or" construction, the first half is "do not have", a tensed verb. therefore, the second half of the construction must also contain a tensed verb.
(a) and (b) don't have a tensed verb ("likely to have" contains only an infinitive - not what we want here).

--

as you've said, (e) contains a double negative, so it's out.

--

(c) is, as far as i can tell grammatically correct (although the commas are superfluous in such a construction), but it's simply absurd. the use of "or" here creates a sentence that is weirdly self-contradictory.
the clear point of the sentence is that the schools don't have enough computers, so you need to select the choice that's grammatically correct but also in line with that meaning. (d) is the only choice that satisfies both criteria.
