★ 动词三单形式的变化规则:
1. ( 1)多数直接在动词词尾加 -s. play — plays like — likes ask---asks work---works get---gets call---calls
(2) 以字母s, x, ch, sh 或o结尾的动词,在词尾直接加-es. watch---watches wish---wishes do---does go---goes

2. 不规则变化: be -- is have ------ has 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 is my sister..
疑问句f Is she your sister? Yes, I am./ No, I ' m not. 否定句f She is not my sister.
②陈述句: I can play soccer.
疑问句f Can you play soccer? Yes,lcan./ No, I can ' t. 否定句f I can not /can ' t play soccer.
★注意:对一般疑问句的回答:
— 一般用什么问就用什么来回答。

Is that your backpack? Yes , it is./ No, it isn ___________ ' t. Are these your parents? Yes, they _____ o, they aren ' t. Are those Jim ' s brothers? Yes, they ' re./ No, they aren ' t. (3) 当句子中没有be动词,也没有情态动词时,变一般疑问句时,在主语前加 助动词do (I, we, you, 以及复数),does (第三人称单数she,he,it 等)变成 问句; (4) 变否定句时,在主语后谓语动词前加助动词 don' t, doesn ' t变成否定 句,切记:助动词后的动词则还原成动词原形。
例:①陈述句: We get up (起床)at 7:00 every morning. 疑问句f Do you get up at 7:00 every morning? 否定句f We don' t get up at 7:00 every morning. ②陈述句:She has a brother.
疑问句f Does she have a brother? 否定句f She doesn ' t have a brother. 探 在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单 数形式,即常在动词原形后加-s或-es。
但有些同学们对于哪些主语是 第三人称单数 还不十分清楚, 现归纳总结如下: 一、 人称代词he, she, it 是第三人称单数。如: He likes watchi ng TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 二、 单个人名、地名或称呼作主语;是第三人称单数。 女口: ① Han Mei likes salsd . 韩梅喜欢萨拉。 ② Beiji ng is in Chi na. 北京在中国。 ③ Un cle Wang ofte n plays volleyball.. 王叔叔经常打排球。 三、 单数可数名词或\单数可数名词\作主语时,是第三人 称单数。女口:

六、 当数字或字母作主语时,看作第三人称单数 。如: ① \是个吉利数字。 ② \是个字母。 、按照要求改写句子
