Question

—Where have you _____ all day? —I came back at noon and I ____ in this room ever since.

A．gone; had been	B．gone; was
C．been; have been	D．been; am

Answer 1

C

解析试题分析：句意：你整天都去了哪里？我在中午回来的，自从那时起我一直在这个房间里。have been to曾经去过某地，强调经历，如果是地点副词to 要省略。have gone to去了某地，表示不在这里。ever since现在完成时的标志词，故选C。
考点：考查现在完成时的用法。
