现在完成时
一、其构成
"助动词hav. gone to     C. been in      D. been to
析：据句中的have，排除A，B项意为"去某地了"，C项意为"一直呆在某地"，D项意为"去过某地"，符合题意，故选D。
2. My parents ______ Shangdong for ten years.
A. have been in    B. have been to    C. have gone to     D. have been
析：本题句中有"for+段时间"结构，据此可排除C，B项意为"去过某地"，不合题意，D项缺介词，故选A。
四、现在完成时与其他时态的联系和区别。如：
1. Sun's aunt has gone there for ten years.(改成正确的句子)
析：非延续性动词与"段时间"连用时，除了把非延续性动词改成延续性动词外，还可把动词改为一般过去时或借助句型"It's +段时间+since+从句"进行句子转换。故答案为：Sun's aunt has been there for ten years. /Sun's aunt went there ten years ago. /It's ten years since Sun's aunt went there.
2. Susan has been in this city for more than ten years.(改为同义句)
________more than ten years ____Susan ______to this city.
析：据上题分析，且since引导的从句要用一般过去时，故填It is, since, came。
3. I won't go to the concert because I ____my ticket.
A. lost   B. don't lose   C. have lost   D. is coming
