典型例題
She reached the top of the hill and stopped ___on a big rock by the side of the path.
A. to have restedB. resting C. to restD. rest
答案：C。由題意可知，她到了山頂，停下來(lái)在一個(gè)路邊的大石頭上休息。因此，應(yīng)選擇"stop to do sth. 停下來(lái)去做另一件事"。而不僅僅是爬山動(dòng)作的終止，所以stop doing sth。不正確。
stop doing/to do
forget doing/to do
forget to do忘記要去做某事。(未做)
forget doing忘記做過(guò)某事。(已做)
The light in the office is stil on. He forgot to turn it off. 辦公室的燈還在亮著，它忘記關(guān)了。(沒(méi)有做關(guān)燈的動(dòng)作)
He forgot turning the light off. 他忘記他已經(jīng)關(guān)了燈了。( 已做過(guò)關(guān)燈的動(dòng)作)
Don't forget to come tomorrow. 別忘了明天來(lái)。(to come動(dòng)作未做)
典型例題
---- The light in the office is still on。
---- Oh, I forgot___.
A. turning it off B. turn it off C. to turn it off D. having turned it off
答案：C。由the light is still on 可知燈亮著，即關(guān)燈的動(dòng)作沒(méi)有發(fā)生，因此用forget to do sth。
而forget doing sth表示燈已經(jīng)關(guān)上了，而自己忘記了這一事實(shí)。此處不符合題意。
