Question

9.What we need ______good textbooks. A. is B. are C. have D. has

选了A 为什么错了。

Answer 1

因为语法书上说不能这样用。
实际上像这样的题已经跟不上形势了。在现实生活中，人们多是跟着主语来选择谓语单复数形式，并非一定要照顾到后面的表语是单数还是复数。也就是说，在上述例子中，用 is 并不能算错。这类例子不难找到：
"What we need is more people who specialize in the impossible." - Theodore Roethke
“What we need is more WikiLeaks about the Federal Reserve,” he said.
What you're going to do today is to tour around the factories and to meet with employees.

聪明的出题者是不会在考试中出这种引起争议的题的。

Answer 2

textbooks是复数，所以is不对
