A. to have restedB. resting C. to restD. rest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。,2) forget doing/to doforget to do忘记要去做某事。(未做)forget doing忘记做过某事。(已做)The light in the office is stil on. He forgot to turn it off.办公室的灯还在亮着，它忘记关了。(没有做关灯的动作)He forgot turning the light off. 他忘记他已经关了灯了。 ( 已做过关灯的动作)典型例题- 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 可知灯亮着，即关灯的动作没有发生，因此用forget to do sth. 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。,3) remember doing/to do remember to do 记得去做某事 (未做)remember doing记得做过某事 (已做) Remember to go to the post office after school. 记着放学后去趟邮局。 Don't you remember seeing the man before? 你不记得以前见过那个人吗?,4)regret doing/to do regret to do 对要做的事遗憾。(未做) regret doing 对做过的事遗憾、后悔。(已做) I regret to have to do this, but I have no choice. 我很遗憾必须这样去做，我实在没有办法。 I don't regret telling her what I thought. 我不为告诉她我的想法而后悔。典型例题-You were brave enough to raise objections at the meeting. -Well, now I regret _ that.to do B. to be doing C.to have done D.having done答案：D。regret having done sth. 对已发生的事感到遗憾。regret to do sth. 对将要做的事感到遗憾。本题为对已说的话感到后悔，因此选D。,5) cease doing/to do cease to do 长时间，甚至永远停做某事。 cease doing 短时停止做某事，以后还会接着做。That department has ceased to exist forever. 那个部门已不复存在。 The girls ceased chatting for a moment when their teacher passed by.姑娘们在老师走过时，停了会聊天。6) try doing/to do try to do努力，企图做某事。try doing 试验，试着做某事。 You must try to be more careful.你可要多加小心。 I tried gardening but didn't succeed. 我试着种果木花卉，但未成功。,7) go on doing/to do go on to do做了一件事后，接着做另一件事。 go on doing 继续做原来做的事。 After he had finished his maths，he went on to do his physics. 做完数学后，他接着去做物理。8) be afraid doing/to do be afraid to do不敢，胆怯去做某事，是主观上的原因不去做，意为"怕"；be afraid of doing担心出现doing的状况、结果。 doing 是客观上造成的，意为“生怕，恐怕”。She was afraid to step further in grass because she was afraid of being bitten by a snake. 她生怕被蛇咬着，而不敢在草丛中再走一步。She was afraid to wake her husband. 她不敢去叫醒她丈夫。She was afraid of waking her husband. 她生怕吵醒她丈夫。,9) mean to doing/to do mean to do 打算、想mean doing意味着I mean to go, but my father would not allow me to.我想去，但是我父亲不肯让我去。To raise wage means increasing purchasing power.赠加工资意味着增加购买力。,感官动词 + doing/to do 感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel + do 表示动作的完整性，真实性；+doing 表示动作的连续性，进行性I saw him work in the garden yesterday.昨天我看见他在花园里干活了。(强调"我看见了"这个事实)I saw him working in the garden yesterday. 昨天我见他正在花园里干活。 （强调"我见他正干活"这个动作）典型例题1）They knew her very well.
