小学一般现在时

当我们谈论以下几种情况时,用一般现在时。

1、表示经常性,习惯性的动作。(常与表示频率的时间状语连用。)

2、表示现在存在的状态。

3、表示客观事实或普遍真理。

标志词(时间状语):always, uauslly, often,sometimes,never,every week (day, year, month?) at?, on Sunday,....

一、肯定句(看主语)

主语第一,二人称单复数,第三人称复数和复数总是加动原;除非主语是三单,三单动词变一变s/es.

例如:I/We/You/You / They/Boysand girls like reading books. Amy /She/ He likes reading books.

二、变否定(找动词)

动原前加don’t;三单前加doesn’t后面动词改原形.

例如: I often play (动词原形) football in the park. { ↓

I often don’t play(动词原形) football in the park.

He (三单动词) TV at home.

↓ ↓

He doesn’t watch (动词原形)TV at home.

三、变疑问(找动词)

动原句首加do;如果动词是三单,助动词does句首请,主语紧随在其{

后,动词改原形。

例如: They go (动词原形) to school on foot. {

{ ↙ ↓

Do they go (动词原形) to school on foot?

She (三单动词) to school by bus.

↙ ↓

Does she go (动词原形) to school by bus?

一般现在时动词 “单三” 的变化规则

1. 一般在动词结尾直接加s

e.g. help --- helps climb --- climbs talk --- talks sing --- sings

2. 以s, x, ch, sh, o结尾的动词加es;

e.g. teach --- teaches guess --- guesses wash --- washes watch --- watches go --- goes do --- does

3. 如果词尾已有e, 直接加s

e.g. close --- closes dance --- dances

love --- loves like --- likes

4. 以辅音字母 + y结尾的动词, 变y为i后, 加es e.g. study --- studies fly --- flies

5. 以元音字母+ y结尾的动词,

e.g. play---plays

say ---says.

stay---stays

s; 结尾加
