语法篇之-现在完成时1.什么是现在完成时? 表示过去发生的动作对现在造成的影响或结果。 表示说话之前发生的动作,可能发生过一次,也可能发生过多次。 2.与一般过去时的区别? 一般过去时是过去某一特定时间你做的事情,你就是在描述你过去那时侯在干吗 现在完成时是从现在为起点,除了你可以从 since,for 中看出这是完成时以外,这个时态 代表的是一个时间段中,她已经做了什么。另外这个时态强调的是对现在的影响,或者可 以影响到现在的行为。 3. 现在完成时的构成 助动词 Have (has) +动词的过去分词 4.过去式和过去分词的区别? 一、形式上的区别 1、规则动词的过去式和过去分词没有区别,基本都是在动词后面加上 ed。 2、不规则动词的过去式和过去分词有些不一样,但也有不少是一样的。比如 read,它的 过去式和过去分词和动词原形是一样的,只是读音有所区别。 二、意义上的区别 动词的过去式和过去分词实际上都是用来描述一个“已经发生的行为”,区别只是着重点不 同,过去式着重点在“行为本身”,相当于汉语的“了”。过去分词着重点在“行为的结果或 影响”,也就是说动词的过去分词主要是用于说明相当于汉语“已”或“被”这样的概念。 4.现在分词的构成? 规则动词的过去式和过去分词是一样,不规则动词的过去式、过去分词如下表不规则动词过去式、过去分词表不规则动词过去式、过去分词表(1) AAA 型(动词原形、过去式、过去分词同形)型(动词原形、过去式、过去分词同形) cost(花费)(花费)cost cost cut(割)(割) cut cut hit(打)(打) hit hit hurt(伤害)(伤害) hurt hurt let(让)(让) let let put(放)(放) put put read(读)(读) read read (2) AAB 型(动词原形与过去式同形)型(动词原形与过去式同形) beat(跳动)(跳动) beat beaten (3) ABA 型(动词原形与过去分词同形)型(动词原形与过去分词同形) become(变成)(变成) became become come(来)(来) came come run(跑)(跑) ran run(4) ABB 型(过去式与过去分词同形)型(过去式与过去分词同形) dig(挖)(挖) dug dug get(得到)(得到) got got hang(吊死)(吊死) hanged hanged hang(悬挂)(悬挂) hung hung hold(抓住)(抓住) held held shine(照耀)(照耀) shone shone sit(坐)(坐) sat sat win(赢)(赢) won won meet(遇见)(遇见) met met keep(保持)(保持) kept kept sleep(睡)(睡) slept slept sweep(扫)(扫) swept swept feel(感觉)(感觉) felt felt smell(闻)(闻) smelt smelt leave(离开)(离开) left left build(建设)(建设) built built lend(借出)(借出) lent lent send (传送)(传送) sent sent spend(花费)(花费) spent spent lose(丢失)(丢失) lost lost burn(燃烧)(燃烧) burnt burnt learn(学习)(学习) learnt learnt sell(卖)(卖) sold sold tell(告诉)(告诉) told told mean(意思)(意思)meant meant catch(抓住)(抓住)caught caught teach(教)(教) taught taught bring(带来)(带来)brought brought fight (战斗)(战斗) fought fought buy(买)(买) bought bought think(想)(想) thought thought hear (听见)(听见)heard heard say(说)(说) said said find(找到)(找到) found found have/has(有)(有) had had make(制造)(制造) made made stand(站)(站) stood stood understand(明白)(明白)understood understood现在完成时练习题现在完成时练习题一、用一、用 sincesince 和和 forfor 填空填空1._two years 2. _two years ago3. _last month 4. _ 19995._yesterday 6._ 4 oclock7. _ 4 hours 8._an hour ago9. _we were children 10._ lunch time11. _she left here 12.
