问题补充：
Mr. Lee, who as a carpenter for over 10 years, is now a very famous statesman in this country.
A. has worked
B. had worked
C. worked
D. works
答案：
A. has worked
B. had worked
(答案→)C. worked
D. works
解析：考查动词的时态。根据is now a very famous statesman in this country，可知他作为木匠是过去发生的事，现在已不是，选A表明现在还是木匠，不符合句子，排除；had worked过去完成时态，用在过去的过去，不符合句子，排除；所以选C，一般过去时态。
