问题 ______, computer has played an important role in modern life.
选项 A、What is known to all
B、Since it is known
C、As long as it is known
D、As is known to all
答案 D
解析 句意：众所周知，计算机在现代生活中起着重要的作用。What is known to all后面通常接is that…+从句，what引导主语从句。Since it is known后面也接that+从句，引导原因状语从句。As long as意为“只要”。A、B、C三项均不符合句子逻辑，故正确答案为D。
