I am an English teacher. Are you an English teacher?Eg7. We can speak English fluently. Can you speak English fluently?2、第二家族：含行为动词（或称为实义动词）的句子秘诀：一加二变三问号一加：即在句首加助动词Do或Does； 二改：1、把谓语动词改为原形；2、改换主语称谓（同第一家组）；some改为any，and改为or。三问号：句末的句号改为问号。Eg8. We read English every morning. Do you read English every morning?Eg9. Toms father listens to English every evening. Does Toms father listen to English every evening?特别注意：对于第二家族一定要注意动词的还原，因为时态与数的变化已经体现在助动词上了。3、 加强记忆口诀：“肯变一，并不难，can 或be提在前；谓语若为行为动，do 或does句首用，（是三单要还原）”五、特殊：肯定句变否定句和一般问句时1.some变为any。如： There are some birds in the tree.There arent any birds in the tree. 但是，若在表示请邀请、请求的句子中，some可以不变（即some用于表示请求，征询意见的问句中，表示语气委婉）。如： Can I bring some books to school?(此时表示请求，语气委婉，用some)2.and变为or。如： I have a knife and a ruler.I dont have a knife or a ruler. 3.a lot of (=lots of)变为many或much。如： They have a lot of friends.（可数名词）They dont have many friends. There is lots of orange in the bottle.（不可数名词） There isnt much orange in the bottle. 练习，变否定，一般问句并作否定回答。1. It is a yellow bag. 2. This is my English book. 3. Those are our friends. 4. Tom and Jam_( have) some photos. 5. I am a middle school student . 6. I can speak English . 7. We come from America . 8. He_(like)his brother . 9.

Tom can take a lot of books to school.知识点3. 动词单数第三人称专练 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 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。 二、单个人名、地名或称呼作主语；是第三人称单数。如： Han Mei looks like her mother.韩梅看起来像她的母亲。 Beijing is in China.北京在中国。 Uncle Wang often makes cakes.王叔叔经常做蛋糕。 三、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： A horse is a useful animal.马是有用的动物。 This book is yours.这本书是你的。 That car is red.那辆小汽车是红色的。 四、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： Everyone is here.大家到齐了。 This is a pen.这是一支钢笔。 五、不可数名词作主语时为第三人称单数。如： The milk is in the glass.牛奶在玻璃杯里。 The bread is very small.那面包很小。 六、当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number. 6是个吉利数字。 I is a letter. I是个字母。 巩固练习题：肯定句的现在时，不是三单用原形，是三单就加s，es。若是否定疑问句，没有be就加个do，碰到三单加does。I.写出下列动词的.第三人称单数： wash_ listen _ guess_ study_do_ go_ like _ carry_ come_eat _ run _play _ give_ photo_ watch_have_II.用所给动词的适当形式填空： 1I _(write) to my sister every week.2.
