〔TheSimplePresentTense〕

一般现在时表示经常发生的、习惯性的动作或存在的状态。其时间状语为often、usually、always、sometimes等频率副词，onSaturdays、inthemorning(afternoon/evening)

、everyday〔week/year〕等.二．只有主语在第三人称单数时用动词的“三单形式〞，其他人称用动词原形。动词三单形式的变化规那么：〔1〕多数直接在动词词尾加-s

play

plays

like

askasks

workworks

getgets

callcalls

〔2〕以字母s,

x,

ch,

sh或o结尾的动词，在词尾直接加-es.

watchwatches

wishwishes

dodoesgogoes

〔3〕以“辅音字母加-

y〞结尾的动词，要先变y为i再加-estrytriesstudystudies

crycries

flyflies

不规那么变化：be

ishavehas

三、一般现在时的句子转换：〔1〕变一般疑问句：当句子中有be动词或情态动词时，那么把be动词或情态动词(can,could等)提到主语的前面，〔口诀：一调二变三问号〕〔2〕变否认句：在be动词或情态动词后面直接加not变成否认句

(be〕后not莫忘记)

例：①陈述句：She

is

my

sister.否认句→

She

is

not

my

sister.疑问句→

Is

she

your

sister?

②陈述句：I

否认句→
