问题
_______ is the center of our planetary system was a difficult concept to grasp in the Middle Age.
选项
A、It is the sun and not the earth
B、Being the sun and not the earth
C、The sun and not the earth
D、That the sun and not the earth
答案
D
解析
根据句子结构我们可以看出,在was前面是一个主语从句,而主语从句必须有引导词,但A,B和C中都没有引导词,因此三个均错。D中that引导主语从句,在句中不作任何成分,只起引导词的作用,因而D是正确答案。
