The Pet Place opened almost eight years ago, and it has ________to be a very successful enterprise.
A、improved
B、approved
C、proved
D、disapproved
【正确答案】：C
【名师解析】:The correct answer is C, "proved." The sentence is discussing the outcome of The Pet Place over the past eight years. The word "proved" fits best in the context as it means to demonstrate or show something to be true through evidence or results. In this case, The Pet Place has demonstrated through its performance over the years that it is a very successful enterprise. The other options do not fit as well: "improved" suggests a process of becoming better, "approved" implies a formal acceptance or endorsement, and "disapproved" would mean a formal rejection or disagreement, which does not align with the success mentioned in the sentence.
