24.___________ is known to all, the earth moves around the sun once a year.
A That B. As C. What D. It
[B]本题考查的是as 引导的非限制性定语从句,as 指代后面的整个句子,句意为:正如大家所知道的,地球一年绕太阳转一圈。这种表达方式已经相对固定了如果此处填it ,这句话应该这样表达:It is known to all that the earth moves around the sun once a year. that the earth moves around the sun once a year是主语从句后置,it 只是个形式主语。选项that 不能引导非限制性定语从句,what不能引导定语从句。
