问题描述:

选择Didn't you know the sun _____in the east?
选择Didn't you know the sun _____in the east?A.rise B.rises C.roseD.rising

普通从句,主句是过去时的话,从句一般也是用过去的某种事态。但
"the sun rises in the east"(太阳从东方升起)是一种普遍的客观事实;从句仍然用现在时,不受主句时态的影响。
选B

A
前面know是base form, 后面也是base form
所以就是Didn't you know the sun rise in the east?

B
当主句是一般过去时 ( Didn't ),在宾语从句中,如果是客观规定仍然用一般现在时
翻译: 难道你不知道太阳在东方升起吗

D
