问题
Some Martian rock structures look strikingly like structures on Earth that are known ______ by microbes.
选项
A、having been created
B、being created
C、to have been created
D、to be created
答案
C
解析
空格所在的定语从句为“sth.be known to do”结构,因此排除A、B项。that指代structures on Earth,与created之间存在被动关系,故要用被动式,C、D都符合。地球的岩石结构早已由微生物创造出来,即created动作先于are known发生,故选C。
