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

解析試題分析：句意：你整天都去了哪里？我在中午回來的，自從那時起我一直在這個房間里。have been to曾經去過某地，強調經歷，如果是地點副詞to 要省略。have gone to去了某地，表示不在這里。ever since現在完成時的標志詞，故選C。
考點：考查現在完成時的用法。
