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

often 是不是要去掉呢
kept是不是要改成keeping
He used to keeping the office clean when he was at work
???

这个句子不对
often应该去掉,因为often只用在现在时中
如果你想表达他过去经常这样做的话就用used to do sth
能把题目打清楚点吗

没什么问题
