小学时态综合讲解与练习

一、 一般现在时的用法

A、当谓语是be动词时，构成为：主语+be动词( am, is, are )+其他。如：I am a student. B、当谓语是行为动词时，构成有两种：

（1）主语（非第三人称单数）+动词原形+其他。如：We often watch TV at the weekends. （2）主语（第三人称单数）+动词第三人称单数形式+其他。 如：Jim usually goes to the park on Sundays. C、句型变换：

肯定句 否定句 一般疑问句及回答

They watch TV at six everyday. They don’t watch TV at six everyday. ---Do they watch TV at six everyday. ---Yes, they do. / No, they don’t.

She watches TV at six everyday. She doesn’t watch TV at six everyday. ---Does she watch TV at six everyday. ---Yes, she does. / No, she doesn’t. 肯定句 They watch TV at six everyday. everyday.

1． “是”动词的现在式是：am，is和are。其用法如下 (1) I a teacher. (2) You a student. (3) He a worker

2． “有”动词的现在式是：have (got)或has (got) (1) I a book. I ( not) a book. (2) He a radio. He (not) a radio

3．如果主语是第三人称单数，谓语动词要用第三人称单数形式，如果主语是其他人称，谓语动词用动词原形。

如：We study English well. He studies English well. (1) She (like) playing football

(2) WangHua (love) animals very much. (3) I ( enjoy) watching TV every weekend. (4) We (play) football every day

否定句 They don’t watch TV at six everyday. six everyday. 一般疑问句及回答 ---Do they watch TV at six everyday. ---Yes, they do. / No, they don’t. ---Does she watch TV at six everyday. ---Yes, she does. / No, she doesn’t. She watches TV at six She doesn’t watch TV at

二、什么情况下用一般现在时？

1．表示经常性或习惯性的反复发生的动作

(1) Sometimes she ( go) to see a film in the evening (2) How do you usually ( come) to school? (3) He often (watch) TV on Saturdays 2．表示现在的状态或特征

(1) This book (be) easy to read. (2) Lily (draw) well.

(3) It often ( rain) here in summer (4) I ( have) a dictionary 3．表示客观事实或普遍真理：

(1) Winter (be) colder than summer in China (2) The earth ( move) round the sun.

(3) The sun (rise) in the east and (set)（落下）in the west. (4) The light (travel) much faster than the sound.

(5) Shanghai (be) in the east of China

4．常与一般现在时连用的时间状语有：often, sometimes, usually, always, every day( week, year, month) on Sundays, in the morning( afternoon, evening)等。

二、现在进行时的用法。

1．现在进行时：它是由“主语+be动词+实义动词的-ing形式”构成的，表示正在发生和进行的动作或存在的状态。如：Now I am talking，and you are listening.现在我在讲，你在听。

2．判断依据：句中往往有now、look、listen等词。注意：千万不要忘了一定得有be动词。 3．句型变换： 肯定句 I am working. You are working. He/She/It is working. 否定句 I am not working. You are not working. He/She/It is not working. are working.

疑问句及回答 Are you working? Yes,I am. No,I am not. Yes, we are. No, we aren't. not Are they working? Yes, he/she/it is. Yes, they are. No, they aren't. Is he/she/it working? No, he/she/isn't. We/You/They are working. We/You/They

4．两种进行时的基本法：一种与now连用；另一种是与一些表示一段时间的词连用，表示现阶段正在进行的动作。也常与listen/hear/look特征词和具体的时间、具体的地点状语连用。

5．一般情况下，实义动词是可以直接加“-ing”的，但有两种特殊的情况是需要有一些变化的。第一种是像put和get这样以一个元音字母加一辅音字母结尾并重读的实义字母，需双写结尾的辅音字母再加-ing，就是putting和getting。第二种是以不发音的e字母结尾的实义动词，要把“e”去掉，再加-ing，如dance-dancing（跳舞），come-coming（来）；另外以ie结尾的实义动词要把ie变y再加-ing， 如lie-lying（躺：说谎），die-dying（死），tie-tying（捆绑）。

一、写出下列动词的现在分词形式。

Stay do listen suffer refuse close operate die work spend look make put sit run tie begin open lie

二、按要求改写句子。

1. The boy is playing basketball

否定句： 一般疑问句： 肯定回答： 否定回答： 对“The boy”提问： 2．造句：

(1) she，the window, open，now.（用现在进行时连词成句）

(2) is．who, the window, cleaning?（连词成句）

(3) they, the tree，sing，now, under.（用现在进行时连词成句）

三、用所给的动词的正确形式填空。

1. The boy (draw) a picture now 2. What you (do) now?
