中考英语复习：现在完成时讲解与练习
现在完成时讲解与练习一、构成现在完成时是由助动词h a v e(h a s)+动词的过去分词构成。
助动词说明该谓语是属于现在时范围，它和主语的人称、数要保持一致。
过去分词是主要的谓语动词，说明句子的意义。
二、用法（1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。
常被j u s t、a l r e a d y、y e t等副词修饰。
如：-H a v e y o u h a d l u n c h y e t?-Y e s,I h a v e.I'v e j u s t h a d i t.你（已经）吃午饭了吗？我刚刚吃过。
（现在我不饿了）（2）表示从过去某一时刻开始一直持续到现在的动作或状态。
这个动作可能刚停止，可能仍然在进行。
常带有f o r和s i n c e等表示一段时间的状语。
如：H e h a s t a u g h t h e r e s i n c e1981他自1981年就在这儿教书。
（可能还要继续教）I h a v e n't s e e n h e r f o r f o u r y e a r s.我有四年没见到她了。
（3）表示说话前发生过一次或多次的动作，现在成为一种经验，（即表示过去的经历）一般译为汉语“过”，常带有t w i c e,e v e r,n e v e r,t h r e e t i m e s等时间状语。
如：I h a v e b e e n t o B e i j i n g t w i c e.我去过北京二次。
三、结构1）．陈述句结构：主语＋h a v e(h a s)（n o t）+过去分词＋其它。
h a v e n o t=h a v e n’t h a s n o t=h a s n’t.2）．一般疑问句结构：H a v e(H a s)＋主语＋过去分词＋其它？3）．特殊疑问句：特殊疑问词＋h a v e(h a s)+主语+过去分词＋其它？e g.H e h a s a l r e a d yf i n i s h e d h i s h o m e w o r k.H e h a s n’t f i n i s h e d h i s h o m e w o r k y e t.H a s h e f i n i s h e d h i s h o m e w o r k y e t?--Y e s,h e h a s./N o,h e h a s n’t./N o,n o t y e t.四、现在完成时的时间状语（1）现在完成时属于现在时范围，故不能和过去的时间状语连用。
英语语法教学 现在完成时复习
简析：现在完成时的时间状语常有如下 四类：
⑴ 现在完成时常与already（已经），just （刚 刚，正好），ever（曾经），never （从来，也不；从不），before（以前）， yet（仍然）等连用。
⑵现在完成时常与recently（近来）， so far（到目前为止），in the past/“last + 一段时间”等时间状语连 用。因为上述短语表示的是从现在起往 前推算的一段时间，句中的动作是从过 去某一时间或时刻开始持续到现在的。
１. have/has been to表示“过去曾去过 某地”，但现在已经回来了。
２. have/has gone to表示“已去了某 地”，现在还没有回来。
３. have/has been in 表示“已在某地 （呆了多久）”，如果是小地方用at代替in。
四、中考考点：

现在完成时专项复习和训练
现在完成时时态讲解一、注意弄清时态的实际意义现在完成时表示的是在过去某个时间开始并持续到现在的动作/状态,或者过去的动作或状态对现在造成的影响或结果。
They have left. --他们已经离开了,也就是说现在他们人不在这里I have had my lunch. --我已经吃过午饭了,也就是说我现在不饿也可表示持续到现在的动作或状态，或有可能有可能停止，或有可能继续延续下去。
He has learned English since 2001. -从2001年开始学的,现在还在继续学着呢二、基本句型结构现在完成时的构成形式：have /has (助动词)+done(过去分词)I/You/They/We have talked . He/She has talked.现在完成时的否定结构就是在助动词have或has后加上否定词not；I/You/They/We haven’t(have not) talked . He/She hasn’t(has not) talked.其一般疑问句就是将助动词have或has提到句首，Have I/You/They/We talked . Has he/she talked.肯定的简略回答是：Yes，主语＋have/has.，否定的简略回答是：No，主语＋have/has not.。
如：I have seen the film. →Have you seen the film？Yes，I have./No，I haven’t.三、注意掌握两种基本用法1.“过去的经历”：动作发生在过去的某一时刻且已经结束，但未说明动作发生的具体时间或情景，强调该经历(即动作发生后)对现在所造成的影响或产生的结果。
如：I have heard of the man. 我听说过这个人。
2. “完成情况”：表示过去已经开始并持续到现在的动作或状态，或有可能继续延续下去。
句子中一般有说明其完成情况的短语或从句。
