解析:
1.last year,去年,所以用过去时
2.句意为：对不起,我忘了你的名字.对话用一般现在时.
3.last month,上个月,所以用过去时
4.before,现在完成时的标志,故答案为has never visited
5.yesterday,昨天,故用过去时,lost
6.句意为Bill没有找到他的手表,由于句意限制,过去时最好
7.now是现在进行时的标志,故用are enjoying
8..这一题比较特殊,源于疑问词who,这个词可以做主语,所以不需加助词,因为现在冷是因为过去有人开了窗,所以用过去时
9.后半句句意为我到处都找不到它,前半句句意为,你把盒子放哪儿了?肯定是发生过了,故用过去时
10.结合语境和句意,可知这是一个对话.她去办公室了,肯定还没回来,故用现在完成时.注has gone to somewhere表示去了某地还没回来
