问题
The physicist has made a discovery, ______ of great importance to the progress of science and technology.
选项
A、I think which is
B、that I think is
C、which I think is
D、which I think it is
答案
C
解析
逗号后为非限制性定语从句,修饰a discovery,用which连接,I think可视作插入语,故答案为C。引导词which在从句中可充当句子成分,D项中的it多余;that不能引导非限制性定语从句,B不正确。
