The manager ____ workers how to improve the program since 9:00.
A. has told B. is telling C. has been telling D. will have told
提供答案为C,但是在没有上下语境的情况下,A也是可以的,所以该题不算严谨。
我期盼更多其他专家老师对此的详细评析。
The manager has been telling workers how to improve the program since 9:00.
A. has told B. is telling C. has been telling D. will have told
解答:以上最佳答案为C。应该用现在完成进行时态,即从上午9点一直持续到说话人说指的时间,动作一直都在持续着,中间没有出现暂停或者停止。复数现在完成进行时态所表示语法含义。
