后接定语是用to do sth还是用of doing sth
请看下面一题：
I was excited at his idea _________ rid of the habit _________.
A. to get, to smoke B. of getting, of smoking
C. to get, of smoking D. of getting, to smoke
【分析】此题容易误选A，许多同学认为 one’s idea to do sth, the habit to do sth 等结构读起来很顺口的，感觉也是对的。其实正确答案应是B。英语中有些名词(如time 时间，wish 想法， courage 勇气，decision 决定，ambition 雄心，等)后习惯上接不定式作定语，有些名词(如 idea 想法，habit 习惯，hope 希望, danger 危险，possibility 可能性，等)后习惯上接“of+动名词”作定语，而有些名词(如 way 方法，chance 机会，opportunity 机会，等)则两类结构均可接。如：
I have no wish to go. 我不想去。
I have no hope of going. 我没有去的希望。
This is the best way to do [of doing] it. 这是做此事最好的方法。
