  A. to have rested B. resting  C. to rest D. rest5 R- `( \% n+ k% j5 E, M
  答案:C。由题意可知,她到了山顶,停下来在一个路边的大石头上休息。因此,应选择"stop to do sth. 停下来去做另一件事"。而不仅仅是爬山动作的终止,所以stop doing sth.不正确。6 c( n; |. R! w; ?. W5 D

, O5 b# r; K# B, g& _; X  A. turning it off  B. turn it off  C. to turn it off  D. having turned it off
: e( ^! X% d6 h6 ^$ S1 W  答案:C。由the light is still on 可知灯亮着,即关灯的动作没有发生,因此用forget to do sth.+ P3 e$ p6 Q% r) y& i: D
  而forget doing sth表示灯已经关上了,而自己忘记了这一事实。此处不符合题意
