動名詞的否定式是將否定詞not置于動名詞之前。若動名詞為完成式或被動式，否定詞not應置于整個結構之前。如：
Don’t be angry with me for not having written. 我沒給你寫信請別生我的氣。
He felt bad for not being able to lend a hand. 他因不能幫忙感到遺憾。
I am sure you will excuse me for not speaking to you first. 我肯定你會原諒我事先沒跟你說。
He said he so much regretted not being able to swim. 他說他對不會游泳感到非常遺憾。
She was angry about not having been invited. 她沒被邀請很生氣。
I must offer my apology for not coming to your party. 我沒來參加你的晚會，必須向你道歉。
【注】若動名詞帶有邏輯主語，則否定詞應置于邏輯主語之后。如：
I’m surprised at your not having noticed. 你竟未注意到我感到吃驚。
Jenny’s not having been trained as a dancer is her one regret. 杰妮沒受過舞蹈的專業(yè)訓練是她感到遺憾的事。
