Question

It’s the test system rather than the teachers ________to blame for the students’ heavy burden nowadays.

A．who are

B．whom is

C．that is

D．that are

Answer 1

C

解析试题分析:考查强调句型和主谓一致。分析结构可知此处是强调句型，被强调部分既有人也有物，所以用that，排除A、B选项；被强调部分the test system rather than the teachers在句中做主语，根据主谓一致的原则谓语动词应和the test system 一致，所以正确答案为C。
考点：考查强调句型和主谓一致。
