英语里的be动词，就是am is are.
带有be动词的句型，be动词在里面的主要意思就是“是”
他的句型转换比较简单。
肯定句变疑问句： be动词直接提前，首字母大写，句末变问号。 否定句：be动词后面加not 肯定回答： Yes, 主语+be 否定回答： No, 主语+be+not
肯定句： He is a boy. You are boys. 疑问句： Is he a boy? Are you boys? 肯定回答：Yes, he is. Yes, we are. 否定回答：No, he is not. No, we are not. =isn’t. = aren’t.
否定句： He is not a boy. You are not boys. =isn’t =aren’t
英语中的实意动词句子，实意动词就是有实际动作的动词，比如 jump run see eat like have 等。碰到实意动词的句子，他们句子里面没有be动词am, is,are, 那么他的句型转换就不够用了，这个时候，他就需要助动词（帮助动词的词---do, does.）
肯定句变疑问句，开头统统用do或者does，其他照抄，动词用原型，句末变问号。 肯定句变否定句，在动词前面加上do not（don’t）或者does not(doesn’t)就可以。 肯定回答：Yes. 主语+助动词. 否定回答： No, 主语+助动词+not.
肯定句： He likes apples. They run with dogs. I like eating apples.
疑问句：Does he like apples? Do they run with dogs? Do you like eating apples? 肯定回答：Yes, he does. Yes, they do. Yes, I do. 否定回答：No, he does not. No, they do not. No, Ido not. =doesn’t. =don’t don’t
否定句： He doesn’t like apples. They don’t run with dogs. Idon’t like eating apples. 另外碰到主语是I和we的肯定句，改疑问句时要把I 和we改成you。
带有be动词的句子，单复数变化比较简单，把东西和人物变复数，把is改成are就可以。 He is a boy.----------They are boys. This is a pen.--------These are pens.
实意动词的句子，要注意第三人称后面动词要单数。 我你我们你们是第一人称和第二人称，其他的一个人或一个物体就是第三人称，如he， she， it， Lucy, box, apple等。 He has a pencil. He goes to school.
Ilike swimming.(第一人称原型不用变)
You eat pears.（第二人称动词原型不用变）
肯定句： He likes to eat watermelon. We want to eat food.
否定句：He doesn’t like to eat watermelon. We don’t want to eat food. 疑问句：Does he like to eat watermelon? Do you want to eat food? 对画线部分提问： What does he like to eat? What do you want to eat? 对画线部分提问，划线的东西不能出现，其他部分基本要出现，按实际问的来。
练习：
1、The cat likes to drink milk. 2、He walks to school everyday. 3、Tom is tall in class. 4、Mary has a bird. 改否定句、一般疑问句、有划线的对对划线部分提问
答案：1、The cat doesn’t like to drink milk. Does the cat like to drink milk?
What does the cat like to drink?
2、 He doesn’t walk to school everyday. Does he walk to school everyday? 3、Tom isn’t tall in class. Is Tom tall in class?
4、Mary doesn’t have a bird. Does Mary have a bird? What does Mary have?
