非謂語(yǔ)動(dòng)詞的否定式

　　非謂語(yǔ)動(dòng)詞的否定式通常是就在非謂語(yǔ)動(dòng)詞之前加 not 或 never。如:

　　Try not to make a noise. 盡量別弄出聲來(lái)。

　　He apologized for his not being able to arrive on time. 他因沒能按時(shí)到來(lái)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(guò)他，所以說(shuō)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(diǎn)

　　當(dāng)前面有邏輯主語(yǔ)時(shí)，要放在邏輯主語(yǔ)與非謂語(yǔ)動(dòng)詞之間。如：

　　I’m surprised at your not having noticed. 我對(duì)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。
