① be动词时,主语是I时要用am,主语是you时要用are,其他用is。 ② 是情态动词时,后面动词用原型 ③ 例:I am a student.

He can do his homework by himself. (2) 没有be(am,is, are)动词和情态动词:
主语为第三人称单数(she ,he ,it )、单数可数名词、不可数名词,动词要按规则加上s或es;主语是复数可数名词肯定句,动词用原形。
例:①She(He, It )likes fish. 她(他,它)喜欢鱼。(主语为第三人称单数) ②The table has four legs.桌子有四条腿。(主语为单数可数名词)

They go to school every
day .他们每天都去上学。(主语是复数可数名词,动词用原形) 注意问题:第三人称单数以及第三人称单数时动词变化规则
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:
1、人称代词he, she, it是第三人称单数。如: He likes watching TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 It looks like a cat. 它看起来像只猫。
2、单个人名、地名或称呼作主语;是第三人称单数。如: ①Han Mei looks like her mother. 韩梅看起来像她母亲。 ②Beijing is in China. 北京在中国。
③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。 3、单数可数名词或\"this / that /
the+单数可数名词\"作主语时,是第三人称单数。如:
①A horse is a useful animal. 马是有用动物。 ②This book is yours. 这本书是你。 ③That car is red. 那辆小汽车是红色。 ④The cat is Lucy's. 这只猫是露茜。
4、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时,是第三人称单数。如:
①Everyone is here. 大家到齐了。
②There is something wrong with the watch. 这块手表有毛病。 ③This is a pen. 这是一支钢笔。 ④That is an eraser. 那是一块橡皮擦。

5、不可数名词作主语时为第三人称单数。如: ①The milk is in the glass. 牛奶在玻璃杯里。 ②The bread is very small. 那面包很小。
6、当数字或字母作主语时,看作第三人称单数。如: ①\"6\" is a lucky number. \"6\"是个吉利数字。 ②\"I\" is a letter. \"I\"是个字母。 动词+s变化规则
1.一般情况下,直接加-s,如:cook-cooks, make-makes
runs gets likes collets takes plays climbs
2.以s. x. sh. ch. o结尾,加-es,如:guess-guesses, wash-washes, watch-watches, go-goes
3.以“辅音字母+y”结尾,变y为i, 再加-es,如:study-studies
方法与发音:
1.一般情况下,直接加 -s
eg. works, plays, rains, sees
2.以 sh, ch, s, x 或 o 结尾词后加 –es eg. washes, teaches, fixes, does, goes 3.以辅音字母加 -y 结尾,先把 ‘y’ 改成 ‘i’, 再加 -es
eg. studies, flies, carries 注意: 动词加 -s 以后读音. 动词加-s后读音

由肯定句变为一般疑问句步骤:
①. 把be 动词(am , is , are )或情态动词(may , can , must , should)提前。 ②.大写和小写转换,句首第一个字母要大写。 ③.句末要加问号。
例:肯定句:She is a student . 疑问句:Is she a student ? 肯定句: He can swim. 疑问句:Can he swim? . 疑问句回答:用什么问就用什么来回答。 Is she a student ? Yes, she is . No,she isn’t. Can you swim? Yes, I can . Yes, I can’t.
(2) 句中如果没有be动词(am , is , are )或情态动词(may , can , must ,
should)时,主语为第三人称单数(she ,he ,it )、单数可数名词、不可数名词疑问句要用does 来提问。即在句首加does,句子中原有动词用原形
例:—Does he like Chinese? 他喜欢汉语吗? —Yes, he does. 是,他喜欢(汉语)。 —Does a dog eat meat? 狗吃肉吗? —No, it doesn’t. 不,它不吃(肉)。 (3) 句中如果没有be动词(am , is , are )或情态动词(may , can , must , should)时,主语为复数可数名词疑问句要用do 来提问。 Do you like monkeys? No, we don’t. Do students study Englsih ? Yes , they do.
同时还要注意在肯定句变成否定句时,若是遇I/we→you, my→your. Some→any. 句号→问号(?)
