I _______for an hour but he still _____. A have been waiting; hasn’t turned up B have been waiting; didn’t show up C have been waited; hasn’t turned up D have been waiting; wasn’t turn up

解题思路：见下
解题过程：
答案A
句意：我已经等了一个小时但是他还未露面。
Have been waiting是现在完成进行时，译成“一直在……”
Has turned up 是现在完成时，译成“已经露面” 否定式hasn’t turned up “还未露面”
现在完成时表示“过去的一个动作持续到现在”或者“过去的动作对现在的影响和后果”
这个题突出了以上2个含义。第一空强调“等待”一直持续了一个小时。第二空强调“露面的动作对现在的结果和影响’
1、给分18分。语句通顺灵活。还不错啊小胡同学！
