【答案】D
【解析】
题干句意：不管这块手表花多少钱，它都值。however引导的让步状语从句，相当于no matter how，其结构是however/no matter how + 主谓；主句“it will be worth it.”是一般将来时，从句应当是一般现在时，the watch是第三人称单数，动词cost应当用其三单形式costs。选项D符合题意，故选D。

【解析】
句意：—进来，彼得，我想给你看些东西。—哦，你真好。我从没想过你会给我带个礼物。根据oh，how nice of you可知后句表示在前者说话之前，后者没有想到会有礼物，所以think用过去式，而go用过去将来时。C选项的第2个空错误，D选项的第1个空错误，故选B。

【答案】D
【解析】
句意：杰克到达时，他得知玛丽已经离开了将近一个小时。从题目可以看出应该是用过去式，但后面有an hour表示一段时间，所以应该用延续性动词be away，由于玛丽是已经离开了，所以要用完成时。综合过去时，完成时，延续性动词。答案应该是had been away。故选D。

【答案】A
【解析】
题干句意：—你搬进房子了吗？—还没有。房间正在粉刷。“房间”是“粉刷”的承受着，所以答句应当是现在进行时的被动语态，其动词部分结构为“am/is/are +being+过去分词”，“the rooms”是复数，be动词用are，paint的过去分词是painted，所以动词部分为are being painting。选项A符合题意，故选A。
