问题补充：

Only when Jim was away from home how nice his family was.

A. did he realize

B. he realized

C. has he realized

D. he has realized

答案：

(答案→)A. did he realize

B. he realized

C. has he realized

D. he has realized

解析：

试题分析:考查倒装句。Only+状语并且位于句首时，主句部分要用部分倒装语序，故排除B、D选项。而根据when Jim was away from home可知句子应该用一般过去时，所以A选项正确。句意：直到他离开家以后，他才意识到家是多么的好。
