Great changes ________ in that school. It is no longer _______ it was 20 years ago.
A．have taken place, that
B．have been taken place, what
C．have taken place, what
D．took place, the place what
答案
答案：C
第一空考查词组：take place，不能用被动式，而且这题用现在完成时，表示现在的结果，第二空填what引导表语从句，表语从句中缺少表语，句意是：这个学校已经发生了很大的变化，它不再是20年轻的样子了。选C。
