典型例題

A. to have rested B. resting C. to rest D. rest
答案：C。由題意可知，她到了山頂，停下來在一個路邊的大石頭上休息。因此，應選擇"stop to do sth. 停下來去做另一件事"。而不僅僅是爬山動作的終止，所以stop doing sth.不正確。
2 forget doing/to do

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，即關燈的動作沒有發(fā)生，因此用forget to do sth.
而forget doing sth表示燈已經(jīng)關上了，而自己忘記了這一事實。此處不符合題意。
