问题描述：
112 _______is known to all,China will be an_____ and powerful country in 20 or 30 years’time.
A That ….advancing B This ….advanced C As….advanced D it ….advancing
为什么选C
答
as is known to all是一个短语成分，后面句是句子的主干。如果选择ABD那么这句话就是两句句子，在英语中一句话不可能由两句句子构成，因此只能选C
答
C
as is known to all 众所周知
答
这是一个典型的as 引导的定语从句.as 指后面 China will.这个句子.as 放在句首引导一个定语从句,它的意思是“正如...”
as is known to all 正如大家所知,
As is reported,正如报道的一样,
As is talked about above,如上所说,
答
C
