现在完成时与现在完成进行时 He has taught here since 1981。 他自1981年就在这儿教书。（可能还要继续教） 2、反复：过去某时某刻到现在的经验 I have been to Beijing twice. 我去过北京二次。 3、完成：现在刚完成的工作 I have just stopped reading. 我刚刚停止读书。(读书动作停止) 4、结果：做的某事的结果，对现在仍然有影响。 I have opened the window. 我已经打开窗户了。 下列句型需要用现在完成时： It/this/that is the first/ second time that ... It is the best/ the only/ the first..that ... 现在完成时在从句中，表示动作先于主句动作。 I know all that she has done to me. 标志性词：just,?already,?yet,?before,?twice,?three?times，since，for, in the last few years，so far，recently, never 等。 （4）注意点 have been to 去了已经回来，have gone to 去了没有回来 他已经到香港去了(还没回来)。He has gone to HongKong. 他曾去过香港（去了已经回来）。He has been to HongKong. 现在完成时不能喝明确表示过去的时间状语连用。如yesterday, last night, in 2008,three days ago. 现在完成进行时 （1）构成：have/has been doing （2）用法：表示动作从过去开始一直进行到现在,并且仍在继续中，通常用来谈论较短暂的动作或情况，还可表示一种感情色彩。或者是过去的动作刚刚结束，和现在有关联。 You look hot and tired. Have you been exercising? I’m sorry I am late. Have you been waiting long? I?am?tired.?I??have?been?painting in?the?living?room?all?day.? 三、现在完成时和现在完成进行时的区别 1、现在完成进行时表示动作未结束，仍要继续，有一定的感情色彩。而现在完成时相对强调动作的结果或成就。 a. My hands are very dirty. I’ve been painting the house. b. I have painted the house green. The house was white, but now it’s green. 句a中painting动作一直在持续，活动还没有结束引发的状态是我的手很脏. 句b中painted动作已经结束，动作导致的结果是房间现在是绿色的了。 在表示反复的动作时，现在完成时强调次数，而现在完成进行时强调动作持续的时间。提问分别用how many times 和how long ----How many times have you visited Egypt this mouth? ----twice. ----How long have you been visiting Egypt? ----For two months. I have been drinking five cups of coffee this afternoon.(×) 翻译上句：我下午一直喝５杯咖啡．不和语意．所以现在完成进行时不能表示喝咖啡的次数，而只能用完成时，表示喝完５杯咖啡这个事实． 表示状态和心理的词不能用现在完成进行时。如know，like，hate，love等。 I have known him for years. 近三年高考真题 1. — Look!
