Question

李楠楠的sat语法笔记里 不能pro-verb,per-sentence 不能pro-none;
11．代词pronoun
（it,they,their,which,that）
①singular & plural；
②不能pro-verb,per-sentence；
例：During the labor dispute,barrels of potatoes were emptied across the highway,and they thereby blocked it to all traffic.（P599.4）
(A) highway,and they thereby blocked it to all traffic
(B) highway and thereby blocking it to all traffic
(C) highway,by which all traffic was therefore blocked
(D) highway,and therefore this had all traffic blocked
(E) highway,thereby blocking all traffic
③不能pro-none;

Answer 1

不能pro-verb不能pro-sentence就是代词不能指代动词和句子,只能指代一个名词.
这个题选E,最简练而且语法正确
第三个不能pro-none是抄错了吧,是代词只能pro-noun,就是只能指代名词
