问题
选择题
__________ is known to all, China will he an ________ and powerful country in 20 or 30 years' time.
A．That, advancing
B．This, advancing
C．As, advanced
D．It, advancing
答案
答案：C
题目分析：As is known to all 这是固定搭配，意为众所周知，是一个非限定性定语从句，而advanced 意为先进的、高级的，结合句意，故选C
点评：平时常见的句式要经常在进行积累，另外英语常有一些动词或名词后加ing或者ed变成形容词，要注意。若此题改为___is known to all that China will be an advanced and powerful country in 20 or 30 year’s time.,该怎么办呢？
