问题补充：

in this way, the result seems unsatisfactory, so we’d better have another try.

A. To look at

B. Looking at

C. Looked at

D. To be looking at

答案：

A. To look at

B. Looking at

(答案→)C. Looked at

D. To be looking at

解析：考查非谓语动词。主语the result 与look at之间是动宾关系，故用过去分词。句意：用这种方法看这个结果，似乎令人不满意，因此我们最好再试一试。故选C。
