I.学习目标:复习There be与have/has(got)的用法

II.重难点:There be与have/has(got)的用法和区别

Ⅲ.知识链接:

【结构】使用动词原形do或者第三人称单数does

【用法】 1)经常性、习惯性的动作或存在的状态。

e.g. I go to school on foot on weekdays. / He is very busy every day.

2)表示主语的特征、性格、能力、爱好等。

e.g. He can swim. / I work hard. / She likes watching TV.

【标志】often(经常),usually(通常),sometimes(有时),always(总是),never(从不),on Sundays(在星期天), every day/month/year(每一天/月/年)

【针对练习】

1. My father always __________(come) back from work very late.

2. Where __________ you __________ (have) lunch every day?

3. I often _____(get) up at half past six.

(二)现在进行时:

1. work___________ sing__________ play__________ study__________

2. dance__________ have__________ write__________ take__________

3. run__________ sit__________ shop__________ swim__________

4. lie__________(以ie结尾的动词,把ie改为y, 再加ing) tie_________

【用法】 1)表示现在(说话瞬间)正在进行或发生的动作。常和now连用,有时用动词look!(瞧),listen!(听)来表示“此时此刻”这一时间概念,或者使用祈使句Don’t…引导的句子。

eg. He is watching TV now.现在他正在看电视。

Look! The bus is coming. 看!公共汽车来了。

2)表示当前一段时间内的活动或现阶段正在进行的动作,常和at present(目前),at the moment(此刻),this week(本周),this year(今年), these days(这些天)等时间状语连用。

eg. I’m writing a book this month. 这个月我在写一本书。

We are working on a farm these days. 这些天我们在农场工作。

3)有时可用来表示一个最近按计划或安排要进行的动作。既是说可以用现在进行时来代替将来时。但此时,一般要与表示将来的时间状语连用,而且仅限于少量的动词,例如:go(去), come(来), leave(离开), start(开始), arrive(到达), return(返回), sleep(睡觉) 等。

eg. Are you going to Tianjin tomorrow? 你明天去天津吗?

I know you are arriving next Sunday. 我知道你下个星期天要到。

2. It’s eight o’clock. The students _____(have) an English class.

3. Listen! The baby _____ (cry)in the next room.

4. Don’t talk here. Grandparents _____(sleep).

(三)一般现在时和现在进行时的区别

一、概念不同:

一般现在时表示主语经常性和习惯性的动作或存在的状态,也表示说话者的能力及自然现象。而现在进行时表示说话时(瞬间)正在进行的动作,也表示目前或现阶段一直进行的动作。 如:She often does her homework in the evening. 她经常在晚上做作业。

She is doing her homework now. 现在她正在做作业。

二、在构成方式上的不同:

一般现在时中谓语动词的构成有以下三种情况:

①be动词的一般现在时形式:am,is,are.

②动词have的一般现在时形式:have,has.

③其他行为动词的一般现在时形式有动词原形或第三人称单数形式。

而现在进行时中谓语动词的构成是:am/is/are+动词的-ing形式(现在分词)。

三、时间状语不同:

一般现在时的时间状语主要有:always,usually,often,sometimes,never,every day,on Sundays,in the morning/afternoon/evening等;

现在进行时的时间状语主要有:now,these days,this week,at the moment等,有时句首有“Look!”、“Listen!”或“It’s+时刻”等词、句存在。

如:We play football in the afternoon.我们在下午踢足球。(一般现在时)

My mother is reading a newspaper now. 我妈妈正在看报纸。(现在进行时)

四、感情色彩不同:

一般现在时往往不带任何感情色彩,语气比较肯定。现在进行时常带有一定的感情色彩,并多与always, often等副词连用。

如:Mr. Li works hard in the factory. 李先生在工厂工作努力。(说明事实,语气比较肯定) Mr. Li is always working hard in the factory.李先生在工厂工作一直很努力。(表示赞扬)

五、用语范围不同:

某种表示情感、意识(如want,like,know等);表示“有”的have等动词,一般不用于现在进行时,但可用于一般现在时。

如:我现在就想回家。 误:I am wanting to go home now. 正:I want to go home now.

他有一台电脑。 误:He is having a computer. 正:He has a computer.

六、时间范围不同:

这两种时态所表示的时间范围都可能有“过去——现在——将来”的意味,但相对而言,一般现在时持续的时间较长,甚至无限。而现在进行时持续的时间较短,可能片刻完成。

如:She comes from Shanghai. 她是上海人。She is coming from Shanghai.她正从(或即将从)上海来。

(四)一般现在时和现在进行时的比较

一般现在时表示的是一般、重复的动作或者事情

现在进行时表示说话时或说话前后正在发生的动作或事情,

如:Tom plays tennis every Sunday.

Where’s Tom? -------He is playing tennis.

What do you do? 你是干什么工作的?

What are you doing here? 你在这里干什么?

一般现在时是表示经久的情况,而现在进行时表示的是暂时的,

如:My parents live in Shanghai. They have been there for 50 years.

2

She’s living with some friends until she can find an apartment.
