现在进行时
现在进行时的用法: 其结构是助动词be的过去形式is/are/am +v-ing.
其句式变化仍然要在be上做文章。
现在(说话的瞬间)正在进行或发生的动作,强调“此时此刻”。E.g. He is reading . They are talking now.
2、当前一段时间内的活动或现阶段正在进行的动作。E.g. They are working these days.
3、某些动词的现在进行时,表预定的计划或即将发生的动作。E.g I am coming.
其结构为be+现在分词. 现在分词的变法有
1、一般在动词词尾加上-ing ,E.g. jump
2、以不发音字母e结尾的动词,先去e,再加-ing. E.g have write
3、.以重读闭音节末尾只有一个辅音字母结尾的词,它前面是单个元音字母时要先将词尾的辅音字母双写,再加上-ing. E.g. sit put
其句式变换都在be上做文章。
E.g. He is buying a bike.
Is he buying a bike?
He isn’t buying a bike.
一般由look,listen,now, at this moment等时间状语做标志。
4. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。
Mr. Green is writing another novel.
(说话时并未在写,只处于写作的状态。)
She is learning piano under Mr. Smith.
5. 表示渐变的动词有:get, grow, become, turn, run, go, begin等。
The leaves are turning red.
It's getting warmer and warmer.
6.与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。
You are always changing your mind.
典型例题
My dictionary ___, I have looked for it everywhere but still___ it.
A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.
答案D. 前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时。
不用进行时的动词
1) 事实状态的动词
have, belong, possess, cost, owe, exist, include, contain, matter, weigh, measure, continue
I have two brothers.
This house belongs to my sister.
2) 心理状态的动词
Know, realize, think see, believe, suppose, imagine, agree, recognize, remember, want, need, forget, prefer, mean, understand, love, hate
I need your help.
He loves her very much.
3 ) 瞬间动词
accept, receive, complete, finish, give, allow, decide, refuse.
I accept your advice.
4) 系动词
seem, remain, lie, see, hear, smell, feel, taste, get, become, turn
You seem a little tired.
(一) 、单选

答案:A C A B D
(二)、填空

2、 What____he _____(mend)?
3、 We _____(play)games now.
4、 What ____you____(do) these days?
5、 ____he ___(clean) the classroom?
6、 Who____(sing)in the next room?
7 、The girl____(like)wearing a sweater. Look! She ____(wear)a red sweater today.
答案:1 is lying 2 is mending 3 are playing 4 are doing
5 Is cleaning 6 is singing 7 likes ; is wearing
一、把动词变成现在分词形式易出错
例:1、They are swiming.(swim)
2 、Jenny is plaiing(play)football.
答案:1.swimming 2 .playing
解析:动词变现在分词可有如下口诀:“一添一去y不变”. “一添”指双写规则;“一去”指去掉不发音字母e规则;“y不变”指要与名词变复数区分开。
二、丢掉be动词或忘记把动词变成现在分词
例:1、 Look,two children flying.(fly) a kite in the park.
2 、Li Mingisn’t read ( not read) a book in bed now.
答案:1 are flying 2 isn’t reading
解析:现在进行时肯定句的结构规律为: “be+现在分词,缺一不可”。这一点必须牢记。
三、对动词或动词词组提问时丢掉doing
例:1 、The students are singing in the room.(对划线部分提问)
What are the students in the room?
答案:What are the students doing in the room?
解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”
或简写为“What......doing......”?句式。
四、现在进行时态的选择疑问句中易忽视or后用现在分词形式
例:孩子们在跑还是在跳?
Are the children running or jump?
答案:Are the children running or jumping?
解析: or连接的是两个并列成分,动词形式须一致。
