可以啊。如:she does not do it.

does not後面可以加do，但do是實意動詞做的意思。例如，Li Lei does not do morning exercises every morning.(李雷不是每天早上都做早操。)又如，Mary does not do her homework at home when her parents are away.(瑪麗沒有在家做作業，當她的父母不在家的時候。)

does not後面當然可以加do。

does not或者縮寫成doesn't，這是一般現在時態否定句的助動詞。如果主語是第三人稱單數那麼助動詞就需要加doesn't，如果加了助動詞doesn't那麼動詞就要改成原形。如：He does his homework on Sundays.的否定句是He does not do his homework on Sundays.

donot後面跟動詞原形，具體內容如下。

動詞原形是指使用英語時動詞本身的形態，即與助動詞或情態動詞do，does，did，shall，will，should，would，may，might，can，could，must，need，ought to等一起構成謂語的動詞時，要用原形。感官動詞look at, see, watch, notice, listen to, hear, feel等的賓語與其補足語構成邏輯上的主謂關係，表示動作的最後結果或全過程時，作賓語補足語的動詞要用原形。
