非謂語動詞的否定式

　　非謂語動詞的否定式通常是就在非謂語動詞之前加 not 或 never。如:

　　Try not to make a noise. 盡量別弄出聲來。

　　He told the children not to play in the street. 他叫孩子們不要在街上玩耍。

　　He apologized for his not being able to arrive on time. 他因沒能按時到來而道歉。

　　I told him not to make a mess in the kitchen. 我叫他不要把廚房弄得亂七八槽。

　　Not having finished his work, he could not leave the office. 由于工作沒干完他不能離開辦公室。

　　Not having met him, I cannot tell you what he is like. 我沒有見過他，所以說不出他的模樣。

　　Not having received his letter, she decided to write to him again. 她沒收到他的們，就決定再給他寫一封。

　　二、注意之點

　　當(dāng)前面有邏輯主語時，要放在邏輯主語與非謂語動詞之間。如：

　　I’m surprised at your not having noticed. 我對你沒有注意到感到驚奇。

　　Jenny’s not having been trained as a dancer is her one regret. 詹尼未被培養(yǎng)成一名舞蹈演員，是她的一件憾事。
