一般现在时与一般过去时的讲解与练习

一般现在时的讲解及练习

一般现在时是英语中应用最广泛的时态之一，是初中英语语法重点。

一般现在时表示：

1．经常性、习惯性的动作或存在的状态。

e.g. I go to school on foot. He is very busy now.

2．表示主语的特征、性格、能力、爱好等。

e.g. He can swim. I work hard. I like watching TV.

3．表示客观真理。

e.g. There are seven days in a week. The moon moves round the earth. 其结构按正常语序，即“主语+谓语+其它”，有时为了起强调作用，时间状语也可提前.

其句式变化可分为两种情况：

1．表示动作， 一般人称作主语的，变否定句须在动词前加助动词don’t；变一般疑问句须在句首加助动词do。

E.g. They have lunch at 12:00.

They don’t have lunch at 12:00.

Do they have lunch at 12:00?

2．单三人称做主语的，变否定句须在动词前加助动词doesn’t；变一般疑问句须在句首加助动词does。

E.g. Jenny speaks English very well.

Jenny doesn’t speak English very well.

Does Jenny speak English very well?

含有be动词的要在be上做变化：

E.g. Danny is a good student.

Danny isn’t a good student.

Is Danny a good student?

其时间状语为often、 usually、 always、 sometimes等频率副词，on Saturdays、 in the morning(afternoon evening) 、every day 等。 常见错误如下：

一、be动词与行为动词同时出现在句子中

例：We are plant (plant) the trees in spring.

答案：plant

解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”

自我检测：

(一)、 单选

1． Jenny ____ in an office. Her parents ____in a hospital.

A work; works B works; work

C work; are working D is working; work

2． One of the boys_____ a black hat.

A have B there is C there are D has

3． We will go shopping if it____ tomorrow.

A don't rain B didn't rain C doesn't rain D isn't rain

4． He said the sun ____in the east and ____in the west.

A rose; set B rises; sets C rises, set D rise; sets

5． Wang Mei ____ music and often ____ to music.

A like; listen B likes; listens

C like; are listening D liking ; listen

6． Jenny____ English every evening.

A has study B studies C study D studied

答案：1 B 2D 3C 4B 5B 6B

(二)、填空

1 I can take Li Ming there when he _____ (come) to visit.

2 _____your sister_____(know)English?

3Her home____ _____ ______(远离 )her school.

4The pot_____(not look) like yours very much.

5 Where _____you____(have)lunch every day?

6 Who_____(想要)to go swimming?

7 ______she_____(do) the housework every day?

8 Jenny and Danny usually______(play) games in the afternoon . 答案：1 comes 2 Does know 3 is away from 4 doesn't look

二、单三人称形式易出错

例：1 He plaies (play) football very well.

2 Danny gos (go) to school at 7:10.

答案：1 plays 2 goes

解析：1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；2与名词变复数不同，变单三人称形式以o结尾的词要加es.

三、在句式变换时易出错

例：1 Does Jenny has (has) a good friend?

2 Brian doesn’t lives (not live) in China.

答案：1 Does have 2 doesn’t live

解析：单三人称做主语的一般现在时做句式变化时，可记住如下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g. He didn't go home yesterday.

四、对do的理解易出错

例：We don’t (not do) our homework in the afternoon.

答案：don’t do

解析：do是一个比较难理解的词，它有三个含义:

a)是所有行为动词的总称；

b)是助动词，无实义；

c)是一个具体的行为动词“做，干”。此句中给出的do指“做，干”，not指把此句变为否定句，故须在do前加助动词don’t。

五、对主语的数判断有误

例： Li Ming with me are (be) in Beijing.

答案: is

解析:表面一看是“我和李明两个人在北京”，但with在此做伴随状语，不能做主语，故用is.

另外，宾语从句中，从句部分若是表示客观真理，不管主句是何时态，从句都要用一般现在时；在时间和条件状语从句中，主句表将来，从句要用一般现在时。

一般过去式的讲解与练习

一般过去式表示过去的动作和状态。

如：I met him yesterday. 昨天我碰见了他。

一般过去式构成： 表示一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。

动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化如下：

一般情况下，动词词尾加 -ed ，如：

worked played wanted acted

以不发音的 -e 结尾动词，动词词尾加 -d，如： lived moved decided hoped judged raised

以辅音字母 + y结尾的动词，把-y变为-i 再加-ed，如： Studied tried copied cried carried

以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed，如： stopped begged dragged dropped planned dripped 注：不规则动词的过去式变化规律性不强，须多加记忆。

go - went make - made get - got buy - bought come - came fly-flew

一般过去式的用法：

1) 表示过去某一时刻或某一段时间内所发生的动作或情况，通常一般过去式带有表示动作时间状语的词，词组或从句,如 yesterday, the day before last, last week, two days ago 等,上下文清楚时可以不带时间

状语。

I worked in that factory last year.

去年我在那一家工厂工作。

I went to the Tian Long Mountain yesterday.

昨天我们去了天龙山。

一般过去时表示(1)过去某个特定时间发生，并且一下子就完成了的动作（即：非持续性动作），

(2)可表示过去习惯性的动作。一般过去时不强调动作对现在的影响，只说明过去。

I had a word with Julia this morning.今天早晨，我跟朱丽亚说了几句话。

He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子，抽烟抽得可凶了。

一般过去时常与表示过去的时间状语或从句连用，如：yesterday, last week, in 1993, at that time, once, during the war, before, a few days ago, when 等等。

句子中谓语动词是用一般过去时还是用现在完成时，取决于动作是否对现在有影响。

Have you had your lunch? 你吃过午饭了吗？（意思是说你现在不饿吗？）

Yes, I have. 是的，我已经吃过了。（意思是说已经吃饱了，不想再吃了。）

When did you have it? 你是什么时候吃的？（关心的是吃的动作发生在何时。）

I had it about ten minutes ago. 我是大约十分钟以前吃的。

Used to do something 表示过去常做而现在已经停止了的习惯动作。

I used to work fourteen hours a day. 我过去常常一天干十四个小时。 I eaten it at 6：45。我在六点四十五分吃了。

一般过去时的基本用法

1 带有确定的过去时间状语时，要用过去时

如：yesterday（昨天）、two days ago…（两天前…… ）、last year…（去年…）、the other day（前几天）、once up on a time（过去曾经）、 just now（刚才）、in the old days（过去的日子里）、before liberation（解放前…）、 When I was 8 years old（当我八岁时…）、at+一个时间点 Did you have a party the other day？

前几天，你们开了晚会了吗？

Lei Feng was a good soldier.

雷锋是个好战士。

注意

1在谈到已死去的人的情况时，多用过去时。

2 表示过去连续发生的动作时，要用过去时

这种情况下，往往没有表示过去的时间状语，而通过上下文来表示。 The boy opened his eyes for a moment，looked at the captain，and then

died.

那男孩把眼睛张开了一会儿，看看船长，然后就去世了。

3 表示过去一段时间内经常或反复的动作，常与always，never等连用。

Mrs. Peter always carried an umbrella.

彼得太太过去老是带着一把伞。

（只是说明她过去的动作，不表明她现在是否常带着伞。） 比较

Mrs. Peter always carries an umbrella.

彼得太太老是带着伞。

（说明这是她的习惯，表明她现在仍然还习惯总带着一把伞） I never drank wine.我以前从不喝酒。

（不涉及到现在，不说明现在是否喝酒）

4 如果强调已经终止的习惯时要用used to do

He used to drink.

他过去喝酒。

（意味着他现在不喝酒了。喝酒这个动作终止了）

I used to take a walk in the morning.

我过去是在早晨散步。

（意味着现在不在早晨散步了）

比较：

I took a walk in the morning.

我曾经在早晨散过步。

（只是说明过去这一动作）

5 有些句子，虽然没有表示过去确定时间的状语，但实际上是指过去发生的动作或存在的状态的话，也要用过去时，这一点，我们中国学生往往出错，要特别注意！

I didn’t know you were in Paris.

我不知道你在巴黎。

（因为在说话时，我已经知道你在巴黎了。这句话指的是说话之前，所以只能用过去时表示。实际上，这句话暗指：But now I know you are here.）

I thought you were ill.

我以为你病了呢。

（这句话应是在说话之前，我以为你病了。但是现在我知道你没病） 辨别正误

Li Ming studied English this morning.

（把此句变为一般疑问句）

（×）1.Did Li Ming studied English this morning？

（动词应该用原形）

（×） 2. Does Li Ming Study English this morning？

（时态应该用原句子的时态）

（×） 3.Was Li Ming studied English this morning？

（应该用一般动词，而不是be动词）

（О） 4.Did Li Ming study English this morning？

一般过去时口诀

一般过去时并不难，表示过去动作、状态记心间。

动词要用过去式，时间状语句末站。

否定句很简单，didn't 站在动词原形前，其它部分不要变。

一般疑问句也好变，did放在句子前，主语、动词原形、其它部分依次站。

特殊疑问句也简单，疑问词加一般疑问句记心间。
