一般现在时
一、一般现在时的特征:
1.表示事物或人物的特征、状态。如:The sky is blue.天空是蓝色的。
2.表示经常性或习惯性的动作。如:I get up at six every day.我每天六点起床。
3.表示客观现实。如: The earth goes around the sun.地球绕着太阳转。
二、如何判断句子中的主语是单数第三人称?
句子中的主语S可以归纳以下三类:

三、结构:
1.Be 动词的一般现在时态。.
在没有实义动词的句子中使用be动词,am, is,are
构成:
肯定句: I amWe are He is She is It is They areYou are +表语
如:I am a student. 我是一个学生。
否定句:I amWe are He is She is It is They areYou are +not+表语
如:I am not a student.我不是一个学生。
疑问句:be动词+主语 +表语

(1) 在肯定句中寻找isamare这几个单词
I am a good student. He is a tall boy.
(2)若句子中出现以上几个单词,就直接把这几个单词放到句子的最前面,后面句子
照抄, 注意大小写字母的变化,并把句点改为问号。
I am a good student. →→→→Am I a good student? Are you a good student?
(I am 是特殊的,通常用Are you…?进行提问)
He is a tall boy. →→→→ Is he a tall boy?
They are cute flowers. →→→→ Are they cute flowers?
2. 实义动词的一般现在时态
(1)当主语是第三人称单数时:动词变相应的第三人称单数形式
肯定句:主语+动词s(动词第三人称单数形式)+其它
She likes to eat pizza.她喜欢吃比萨。
否定句:主语+doesn't+动词原形+其它
She doesn’t like to eat pizza.她不喜欢吃比萨。
一般疑问句Does+主语+动词原形+其它
Does she like to eat pizza.她喜欢吃比萨吗?
肯定回答 Yes,主语+does Yes, she does.
否定回答 No,主语+doesn't No, she doesn’t.
(2)当主语不是第三人称单数时:
肯定句: 主语+动词原形+其它
We like to eat pizza.我们喜欢吃比萨。
否定句:主语+don't+动词原形+其它

We don’t like eat pizza.我们不喜欢吃比萨。
一般疑问句 Do+主语+动词原形+其它
Do you like to eat pizza?你们喜欢吃比萨吗?
肯定回答 Yes,主语+do Yes, we do.
否定回答 No,主语+don't No, we don’t.
四、当句子中的主语S是单数第三人称时,动词单数第三人称形式的变形规律如下:
1.大部分的动词+s , 如run→runs , swim→swims, hop→hops等
2.以ch, sh, o, x, s结尾的动词,必须+ es 如:wash→washes,teach→teaches, do→does,
watch→watches,catch→catches, go→goes X, S结尾的动词较少只要记住此概念即可。
3. 以y结尾的动词,有两种情况
a. 动词以y结尾,并且在y字母旁边含有a,e,i,o,u其中一个字母,动词直接+s
如:play→plays (动词中y旁边有a字母) sway→sways
b. 动词以y结尾,并且在y字母旁边不含有a,e,i,o,u其中一个字母,动词必须去掉
y+ies 如:fly→flies, cry→cries, (动词中不含有元音字母)
study→studies (动词中含有u, 但是不在y的旁边,必须去y+ies)
五、不规则变化的动词三单形式:
have---has
六、按要求改写句子
1. My dog runs fast.
否定句: 一般疑问句:
2. Mike has two letters for him.
否定句: 一般疑问句:

一般过去时
一、一般过去时:指已经发生过的动作或事件,至今为止这个动作或事件已经停止。
二、标志词:yesterday, last week, last year, last month, a year ago, a minute ago
Eg: I went to Eric’s party last week.
三、结构:
1.Be 动词的一般过去时态.
在没有实义动词的句子中使用be动词,am, is 的过去式为was; are的过去式为were.
构成:
肯定句:主语+was (were) +表语
如:I was late yesterday. (昨天我迟到了。)
否定句:主语+was (were) +not+表语
如:We weren't late yesterday. (我们昨天没有迟到)
疑问句:was (were) +主语 +表语+表示过去的时间
Were you late yesterday? 你们昨天迟到了吗?
2.实义动词的一般过去时态
肯定句要使用动词的过去式,否定句和疑问句要使用助动词do和does 的过去式did.
肯定句:主语+动词过去式+宾语
I went to school yesterday. 我昨天去了学校。
否定句:主语+didn't +动词原形+宾语
I didn’t go to school yesterday. 我昨天没有去学校。
疑问句:Did +主语+动词原形+宾语
Did you go to school yesterday?你昨天去学校了吗?

四、动词的过去式变形
1.直接加ed:work—— worked look——looked
2.以不发音e结尾的单词,直接加d:live ——lived hope——hoped use——used
3.以辅音字母+y结尾的 (以y结尾, 并且y旁边没有元音字母的动词),变y为i加ed:
study—— studied carry——carried worry——worried
4.重读闭音节动词,要双写最后一个字母, 再加ed
所谓“重读闭音节”:从动词的末 尾开始寻找,如果倒数第二个字母是元音字母,并且
元音字母两边的字母没有组合音,没有变音,都独自 发音,这样的动词都必须,双写
后,以一个辅音字母结尾的,双写最后的辅音字母+ed:stop—— stopped plan——planned
五、不规则变化的动词过去式:
have ---had are---were get---got say---said feel---felt dodoes---did is---was go---went
drink--drank eat--ate bring----brought think----thought buy ----bought catch---- caught
teach ---- taught sit----sat wear----wore cut----cut sweep----swept sleep——slept see----saw
become----became
[1]
read——read
六、按要求改写句子。
are all happy.(改成一般过去时) We _____ all happy.
2. I visited my grandparents last week. (改成疑问句)
__________________________________________________ _____
4. I played a lot of games with my friends in the park. (对划线部分提问)
___________ ____________________________________________
5. I did my homework last night(改成疑问句并作肯定否定回答)
_____________________________________________ ___________

6. There were some ducks in the zoo last year. (改为一般疑问句并作肯定回答)
___________________________ ____________________________________
现在进行时 一、现在进行时:表示正在发生或进行的动作。现在进行时表示动作发生的时间是“现
在”,动作目 前的状态是“正在进行中”。所谓“正在进行中”,是指在谈到这件事的时候,
这个动作还在进行中。至 于它是什么时候开始的,什么时候会停下来,不是我们关心
的。所以“正在进行时”的事件,可能发生几 年了,也可能只有几分钟。仍在进行中这
是“正在进行时”的关键所在。它是一件持续进行的事情。
二、现在进行时常用以下几种情况: (现在进行时标志词:now, at the moment)
1、当句子中有now时,常表示动作正在进行,这时要用现在进行时。
如:They are playing basketball now.现在他们正在打篮球。
2、以look, listen开头的句子,提示我们动作正在进行,这时要用现在进行时。
如: Listen!She is singing an English song.听,她正在唱英语歌。
三、构成:由动词+ v-ing构成。(V-ing表示在动词后面加上ing)
肯定句式:主语 + be( am, is, are)+ V-ing +其它.
e.g I am doing my homework. He is washing his clothes. You are flying a kite.
否定句式:主语 + be(am, is, are) +not + V-ing +其它.
e.g I am not doing my homework. He is not washing his clothes. You are not flying a kite.
一般疑问句:Be(am, is, are) + 主语 + V-ing +其它?
e.g Are you doing your homework? Is he washing his clothes? Am I flying a kite?
e.g What are you doing in the house? Where is he going? When is she doing her homework?
四、动词的ing形式变形
6
北文何老师



1)一般情况在动词原形后直接加 -ing
go---going , stand ---standing , cook---cooking, do---doing
2)以e 结尾的动词,要去掉 e + ing.
take---taking, make---making, have---having
3) 重读闭音节动词,要双写最后一个字母, 再加ing
所谓“重读闭音节”:从动词的末尾开始寻找 ,如果倒数第二个字母是元音字母,并且
元音字母两边的字母没有组合音,没有变音,都独自发音,这样 的动词都必须,双写
后,再加上ing
get- getting , put--- putting, run—running, begin---beginning swim--- swimming
e.g eat---eating 这个动词有ea组合音,所以不能双写
study---studying 这个动词倒数第二个字母不是元音字母,不能双写
4)以 -ie 结尾的动词,把 ie 变成 y ,再加 ing.
die--dying , lie—lying, tie--- tying
五、用所给的动词的正确形式填空:
1. The boy __________________ (draw) a picture now.
2. Listen! Some girls _______________ (sing) in the classroom.
3. My mother _________________ (cook) some nice food now.
4. What _____ you ______ (do) now?
5. Look! They _______________ (have) an English lesson.
6. They ____________ (not, water) the flowers now.
7. Look! The girls ________________(dance )in the classroom .
8. What is our granddaughter doing? She ____________(listen ) to music.

现在完成时
一、现在完成时:表示到说话时 为止(或到现在为止)已经发生或完成了(不一定结
束)的动作或状态。过去某一时间开始并一直持续到 现在并且有可能还会持续的动作
或状态。
二、标志词:
already(已经, 用于肯定句),yet(已经,用于否定,疑问句中),just(刚刚),even
(曾经),sin ce(自从 ) , recently(最近), never(从不)等:
三、构成havehas+动词的过去分词
肯定句中:主语+hashave+动词的过去分词(p.p)(V-ed)+宾语(或者其他)
She has already had her holiday this year.她今年已经度过假了。
否定句中:主语+haven'thasn't+动词的过去分词(p.p)(V-ed)+宾语
She hasn’t had her holiday yet this year.她今年还没有度过假。
一般疑问句中:HaveHas+主语+动词的过去分词(p.p)(V-ed)+宾语(或者其他)
Has she had her holiday yet this year?她今年已经度假了吗?
四、动词的过去分词变形
1.直接加ed:work—— worked look——looked
2.以不发音e结尾的单词,直接加d:live ——lived hope——hoped use——used
3.以辅音字母+y结尾的 (以y结尾, 并且y旁边没有元音字母的动词),变y为i加ed:
study—— studied carry——carried worry——worried
4.重读闭音节动词,要双写最后一个字母, 再加ed stop—— stopped plan——planned
五、不规则变化的动词过去式:
