问题描述：
12.______ any friends in the city,he felt quite lonely and helpless.
A.No to have B.No having C.Not to have D.Not having
为什么not+ing?
答
D
答
首先No是不对的，No表示“没有”，意思上讲不通。Not表示否定后面跟的东西。
Not to have是不打算有的意思，Not having是现在没有的意思。
答
having 在这里是现在分词作原因状语,not表否定,这个句子可以还原为 because he didn't have any friends in the city,he felt quite lonely and helpless.
