動(dòng)名詞的否定形式與分詞否定形式一樣，由動(dòng)名詞前加not構(gòu)成。
例句： She always has dozens of excellent excuses for not being able to help you.
分析： 該句是簡單句。not being able to help you是動(dòng)名詞的否定形式。
譯文： 對(duì)于未能幫助你，她總是有太多借口。
例句： She is considering not asking her mother to send her to the airport.
分析： 該句是簡單句。not asking...作considering的賓語。
譯文： 她正在考慮不讓母親送她去機(jī)場。
