问题 I______my experiment report all the morning and haven’ t finished yet.

选项 A、write
B、was writing
C、have written
D、have been writing

答案 D

解析本题考查时态。句意：我整个上午都在写实验报告，但还没有写完。此句为并列句，and后的时态是现在完成时，haven’t finished yet表示还没有完成，所以前面应该用现在完成进行时，表示动作从某一时间开始，一直持续到现在或可能仍要继续下去。选项D为现在完成进行时，符合语法要求。选项A为一般现在时态，选项B为过去进行时态，选项C为现在完成时态。根据句子结构，本题选D。
