（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.50二．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则：（1）多数直接在动词词尾加-s

play

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

不规则变化：be

ishavehas

51三、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，则把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）变否定句：在be动词或情态动词后面直接加not变成否定句

(be）后not莫忘记)

例：①陈述句：She

my

sister.

否定句→

She

疑问句→
