1.C
have been 表示曾经去过某地 , 而 have gone 表示某人去了某地,当事人不在现场 , 其他两个选项不符合事态,根据句意应选C .
2.D

第一个因为时态 表示时间段 第二个因为change没有被动

1A或B
2B或C
因没讲过被动语态,所以不确定被动语态对不对

1.b 单纯提问过去时 where强调刚才到的地方
2.无答案 排除bc change 应该是changed

1:C 虽然是问你刚刚去了哪,但是后半句说了现在你的手很脏,所以是表示过去与现在的联系。故用现在完成时
2:D 这句为宾语从句,故用陈述语气,从A,C中选,因为王宫是被变成博物馆的,所以用被动,故选D

CD

D C

c用现在完成时have been 表示去过某的 have gone 表示去了某的
d 应有个d
