I’ll never forget the days I spent in the country with the farmers, , of course, has a great effect on my life.
A. that; which
B. when; which
C. that; who
D. when ; who

(答案→)A. that; whichB. when; whichC. that; whoD. when ; who解析：考查定语从句。The days是先行词，定语从句中的spent缺少宾语，故排除when；第二空是非限制性定语从句，用which引导，指前面那件事。故选A。
