she often kept the office clean when she was at work.这个句子对吗,

4个回答

不对,时态上这是一个常态的话（用了often）就应该用一般现在时
she often keeps the office clean when she is at work.
或者去掉often,改成she used to keep the office clean when she was at work.（过去常常）
she often keeps the office clean when she is at work.
前面用keeps已经解释过了
后面的clean是作形容词,自然不能加ed
