②行为动词
否定形式:①am/is/are+not;
②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,
则用does n't,同时还原行为动词。

一般疑问句:
①把be动词放于句首;
②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。

在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。

如:
He likes watchi ng TV. 他喜欢看电视。

She has lunch at twelve. 她十二点吃午餐。

It looks like a cat. 它看起来像只猫。

(口诀:I用am you用are , is用于她他它,单
数名词用is,复数名词都用are)
二、单个人名、地名或称呼作主语;是第三人称单数。

如:
①Han Mei looks like her mother. 韩梅看起来像她的母亲。

②Beiji ng is in Chi na. 北京在中国。

③Uncle Wang ofte n makes cakes. 王叔叔经常做蛋糕。

三、单数可数名词或"this / that / the+ 单数可数名词”作主语时,是第三人称单数。

① A horse is a useful an imal. 马是有用的动物。

②This book is yours. 这本书是你的。

四、不定代词some one, somebody, no body, everythi ng, somethi ng 等及指示代词this, that作主语时,是第三人称单数。

② There is someth ing wrong with the watch. 五、 不可数名词作主语时为第三人称单数。

如: ① The milk is in the glass. 牛奶在玻璃杯里。

② The bread is very small.
那面包很小。

六、 当数字或字母作主语时,看作第三人称单数。

因此when在状语从句中的动词可以终止性动词,也可以是延续性动词
while只指一段时间。

while从句中的动词必须是延续性动词。

②when说明从句的动作和主句的动作可以是同时,也可以是先后生;while则强调主句的
动作在从句动作的发生的过程中或主从句两个动作同时发生。

③when引导的时间状语从句。

后用一般过去时。

While后面一般用过去进行时。

如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,

五、现在完成时:
概念:过去发生或已经完成的动作对现在造成的影响或结果, 或从过去已经开始,
持续到现
在的动作或状态。

(一)
构成:主语+ have/has + V 过去分词。

have /has "如何使用需记清。

当主语是 I , you
和复数名词或代词时要用 have ;单数主语后跟 has 。

也就是说have/has 需同主语的人称或
数保持一致。

(二) 用法 接触一:肯定句式
现在完成时的肯定句式是
have (has )+过去分词”女口:
① We have just fini shed our homework
.
② She has gone home .
注意:1)该句式中的have 或has 是助动词,has 用于第三人称单数,
其它人称一律用 have 。

2 )该句式中have (has )和过去分词之间可用 just 插入。

3
)把该句式译成汉语时,往往用
已经” 刚刚” 过”或了 ”等。

接触二:疑问句式
现在完成时的一般疑问句式是把助动词 have 或has 提到主语之前。

如:
③ Have you read this story book yet
?
(改


句)
特殊疑问句及反意疑问句结构如下:
④What have you done with my bike?
⑤You've read this story book, have n't you?
注意:1)现在完成时的•般疑冋句往往在句末加yet 。

2 )把现在完成时的-一般疑问句译成汉语时,往往译成“••…过吗?”、已经……了吗?'等。

3 )其肯定回答用Yes, ... have (has).”,否定回答用No,... have n't (has n't ). ”,有时用No, not yet ."或No, never . ”。

接触三::否定句式:现在完成时的否定句式是have n't (has n't )+过去分词”。

女口:
⑥ We have n't studied Un it 2 yet .⑦ The train has n't stopped yet
注意:1)现在完成时的否定句句末往往加yet。

2 )否定句常译为还没有……”等。

接触四:用法之一:现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果。

如:
Have you read that story ?你读过那个故事吗?
(读”这一动作发生在过去,对现在造成的影响是:是否知道故事的内容。


I have bought two apples . 我买了两个苹果。

(买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果。


在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already , just , ever, yet , never等。

already , just多用于肯定句中,ever , yet , never多用于疑问句和否定
句中。

如:
I have already fini shed my homework .我已经做完家庭作业了。

He has just had his meal .他刚吃过饭。

Have you ever sung this En glish so ng ?你曾唱过这首英文歌吗?
They have n't started yet .他们还没有动身。

We have never heard of it .我们从来没有听说过这件事。

接触五:用法之二:表示过去已经开始,一直持续到现在的动作或状态。

注:这一用法即现在完成进行时的用法
因为表示的是持续的动作或状态,所以使用的动词通常是延续性动词:be, stay, study, wait, keep, have … 等;
使用的时间状语通常由for或since引导,但二者后接的词有所不同:
for后常跟一个时间段,指某个动作到现在为止已持续了多长时间,如for three years,
for half an hour 等。

since作介词,后面可以接一个时间点,如since 1980,也可以接一段时间+ago”,
女口: since three years ago, since two mon ths ago 等。

since还可用作连词,引导一个过去时态的时间状语从句。

女口:We have known each other since we went to college.
非延续性动词不能直接和for或since连用,但我们可以找一个相应的延续性动词或动词
短语来替换这些非延续性动词,如:come T be, come to be in / at, go out be out, leave T be away, begin / start T be on, stop T be over , buy T have, borrow T keep, open T be open, close T be closed, join T be a member of, die T be dead, catch a cold T have a cold, get to know r know, become a teacher T be a teacher, fall asleep T be asleep, fall ill T be ill 等。

句型It is the first (seco nd, third...) time that... 的that 从句中,谓语动词须
用现在完成时,表示到说话时为止动作发生过几次。

如:It is the first time that I have
bee n here.
接触六:现在完成时与一般过去时的用法比较
现在完成时表示过去的动作对现在造成的影响;一般过去时表示动作发生的时间在过
去。

试比较:
The pla ne has arrived . 飞机已经来了。

(说明现在的情况:飞机在这儿。

)
The pla ne arrived a quarter of an hour ago. 飞机是一刻钟以前抵达的。

(强调动
作发生的时间在过去。

)
接触七:have been in, have been to 与have gone to 的用法
1. have(has) been in 意为已经在某地呆了多长时间”,常与表示一段时间的状语连
用。

They have bee n in Can ada for five years. 他们至U加拿大有五年了。

2. have(has) been to 意为曾经去过某地”,表示现在已经不在那里了。

总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语。

如:
—Where is Tom? 汤姆在哪里?一He has gone to the bookshop. 他到书店去了。

接触八:常用于现在完成时的时间状语
除了我们讲过的already, yet, still , just, ever, never, since 短语和for 短语外,
还有许多时间
状语常用于现在完成时,我们要留心将它们和一般过去时的时间状语区分开来:
1. lately, recently 是完成时的时间状语;just now 有a moment ago 之意,是过去时的
时间状语。

如:
Have you heard from your family lately/rece ntly? Did you see Joa n just now?
2. in the past few years 意思是过去几年来”,常用于完成时中;
in the past 意思是在过去”,常用于过去时中。

女口:

3. ever si nee the n 与from then on / after that 都有打那以后"之意,
但前者常用于完成时,而后两者常用于过去时。

如:

4. before 通常用于完成时;...ago通常用于过去时。

如:

5. so far 到目前为止”,these days 这些天来"也是现在完成时常见的时间状语。

如:

Mr. Smith died yesterday. He had bee n a good friend of mine. 史密斯先生昨天去世
了。

他以前是我的好友。

(5)过去完成时常常用在told,said,knew,heard,thought 等动词后的宾语从句(或间接引
语)中,这时从句中的动作发生在主句表示的过去的动作之前。

He said that he had known her well. 他说他很熟悉她。

(6)状语从句:在过去不同时间发生的两个动作中,发生在前,用过去完成时;发生在后,
用一般过去时。

When I woke up, it had already stopped raining. 我醒来时雨已停了。

She didn 'go to bed until she had finished her work. 她直到把工作做完之后才睡觉。

注意:如果两个动作紧接着发生,则常常不用过去完成时,特别是在包含before和after的复合句中,因为这时从句的动作和主句的动作发生的先后顺序已经非常明确,这时可以用一般过去时代替过去完成时。

After he arrived in En gla nd, Marx worked hard to improve his En glish. 马克思到达
英格兰之后,努力提高他的英语水平。
