人教版八年级英语下册现在完成时态讲解和练习
现在完成时态讲解和练习一、结构现在完成时态由“助动词have/ has+过去分词” 构成陈述句I have lost my pen.否定句I haven’t （have not）lost my pen.一般疑问句Have you lost your pen? Yes, I have. / No, I haven’t.特殊疑问句I have lost my pen. (提问) What have you lost?选择疑问句Have y ou lost your pen or pencil?过去分词变化：(1)与过去式一样：直去双改(2)不规则：AAA ABB ABA ABC AABbuy-bought-bought make-made-made read-read-read write-wrote-written beat-beat-beaten become-became-become 二、基本用法：（一）表示过去的动作或状态对现在造成的影响或结果。
如：（1）He has come 他来了（他现在在这儿）（2）He has turned on the light 他已经把灯打开了（房间是亮的）（3）She has learned to skate 她学过滑冰（她现在会滑冰）（4）He has been to Armenia 他去过美国（他现在不在那里，但知道那里的情况）✧考点探究：1、对这种用法的考查，主要考查学生对现在完成时态的判断。
这种用法强调过去动作对现在造成的影响，因此，在题干中常用一般现在时态或一般将来时态的句子来说明这种影响或结果。
（口诀：前后两句呈因果，必用现在完成时）如：（1）I ___________ (spend) all the money, so I have to walk home.答案为have spent. 花光钱是过去的动作，但对现在造成了影响，“我现在必须得步行回家”。
（2）—Will you go to see the movie, King Kong this evening? —No, I won’t, I ___________ it.(see)答案为have seen。
正是由于“我看过了的”，所对对现在的影响是“我今晚不去看”。
2、常用的时间状语：just刚刚, already已经（只用于肯定句助后实前）, yet还、仍然（用于疑问句和否定句句末）, never从来没有, ever曾经, before以前, once一次, twice两次, many times许多次, so far迄今为止, in(during) the past(last) few years最近几年来等等（二）现在完成时态表示过去开始的动作或存在的状态一直持续到现在或将来，常接for或since短语表示时间段或so far, in the last few years, all day等时间短语。
✧考点探究：1、对for 和since的考查。
for 接时间数量，since后接过去时间点或一般过去时态的从句。
如：(1) I have been here for three years. (2) I have been here since three years ago.(3) I have been here since I came here three years ago.2、这种用法强调过去开始的动作延续到现在，因此就要求谓语动作是可延续性动词。
在考查中就较为注重非延续性动词与延续性动词之间的转换。
如：（1）I came here three years ago→ I have been here for three years.（2）She left home two weeks ago→ She has been away from home for two weeks.注意：非延续性动词与延续性动词的转换有以下几种情况：1）转换成“be+介词短语”结构come → be in / at come back → be backjoin → be in / be a member of begin / start → be on get up → be up2) 转换成“be+形容词”结构die → be dead leave → be away (from) get married →be married finish → be overfall asleep → be asleep close → be closed open → be open fall ill → be ill3) 转换成相应的可延续性的动词buy → have borrow → keep put on → wear catch(get) a cold → have a cold become——be三、重点句型：It is\ has been + 时间数量+ since+从句（一般过去时态）如：It’s two years since he died. He has been dead for two years/ since two years ago. He died two years ago.四、have / has been to 与have / has gone to 的比较。
1、have / has been to “去过某地”，现在已经回来了，后面可接表示“次数”的状语。
如Once, twice等2、have / has gone to “去了某地”，表示已经去了或在途中，还没有返回。
五、一般过去时态与现在完成时态的比较。
1.一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。
注意：一般过去时的时间状语：yesterday, last week, …ago, in 1980, just now, etc.I saw this film yesterday. 我昨天看了这部电影。
（强调看的动作发生过了。
）I have seen this film. 我看过这部电影了。
（强调对现在的影响，电影的内容已经知道了。
）六、巩固练习✧将非延续性动词转化为延续性动词1)He has become a doctor. → He has ________ a doctor for 2 years.2)He has joined the party. →He has ________________the party for 3 hours.3)The shop opened 3 years ago.→ The shop since 3 years ago.4)I have borrowed the book.→ I have ___ the book for 2 weeks.5)She has bought the pen.→ She has ____ the pen for one year.6)She has died.→She for 3 years.✧用所给动词的适当形式填空。
1. I________ already ________ (see) the film. I ________ (see) it last week.2.-- _________ he ________ (finish) his work today?--Not yet.3. My father ________ just _________ (come) back from work.

The students _________ (read) English when the teacher came in.13. Look! The monkey __________(climb) the tree.14. My mother ___________ (come) to see me next Sunday.15.

Our teacher has studied Japanese ___________ three years.4. She has been away from the city ___________ about ten years.5. It’s about ten years ____________ she left the city.✧用“never, ever, already, just, yet, for, since”填空。
1. I have ___________ seen him before, so I have no idea about him.2. Jack has ____________ finished his homework.3. Mr. Wang has taught in this school ____________ ten years.4.-Have you ______________ seen the film?-No, I have ____________ seen it.5. -Has the bus left _____________?-Yes, it has ___________ left.✧用have / has been to / in, have gone to及go的各种形式填空。
