there be 句型造句：1. There are many people on the street these days.（这几天街上有好多人）2. There are so much homework to do that i can not go to bed early.（有如此的多作业要做以至于我不能早睡）3. I am really hungry, is there some food on your desk？（我真的饿了，你桌子上有可吃的吗？）4. There is so much housework to do.（这有很多家务要做） 知识扩展：there be 句型表示“有。
” 一、There be句型的用法：1)There与be中间可插入一些表示推测的情态动词、表示时态的短语和一些动词短语，以强调某种语气。
例如：There must be some flowers in the box. 盒子里肯定有些鲜花。There happened to be some money in my pocket.我的口袋里碰巧有一些钱。
There will be a meeting this afternoon.注意：be不能换成have及have的变化形式。2)There be句型常与过去时间状语连用，构成一些固定句型，用于故事发生的开头，交代故事发生的时间。
例如：Many years ago,there was such a beautiful girl called Caixia.很久以前有一个叫彩霞的美丽女孩。3)There be句型可换成There come / go，以引起注意，加强语气。
例如：There comes the bus公共汽车来了。4)There be句型或There加其他动词的句型，其动词的单复数，常采用就近一致的原则。
例如：There is a desk, two chairs and three benches in the room. There are two chairs, a desk and three benches in the room. 5)There be或There加其他动词的句型，其反意疑问句一律用…there挂 例如：There is a cat in the garden, isn't there挂 There used to be no house here, used there / did there挂（过去这儿没有房子，是吗？） 二、使用There be句型时应注意：1)There be句型中的be 有各种时态。There is going to be a meeting tonight.今晚有个会议。
There was a knock at the door.有人敲门。There has been a girl waiting for you.有个女孩一直在等你。
There will be rain soon.不久天就要下雨了。2）动词be单复数形式要跟there be之后的主语保持一致。
并且要根据就近一致原则来变换be 的单复数形式。例如：There is a book on the desk.课桌上有一本书。
How many people are there in the city挂这个城市里有多少人口。There is a pen and two books on the desk.课桌上有一个钢笔和两本书。
There are two books and a pen on the desk. 课桌上有两本书和一个钢笔。There are some students and a teacher in the classroom. 在教室里有一些学生和一位老师。
There is a teacher and some students in the classroom. 在教室里有一位老师和一些学生。3)there be引到的句子结构中，用来修饰主语的不定式用主动形式和被动形式均可。
例如：There is no time to lose (= to be lost).时间紧迫。There is nothing to see (=to be seen).看不见有什么。
4)There be句型的否定句和一般疑问句。记住下面的口诀：There be句型有特点，主语放在be后边。
例如：（1）. There is a book on the desk. （变否定句） →There is not / isn't a book on the desk. (2). There are some chairs in the room. （变否定句） →There are not / aren't any chairs in the room. (3). There are some boys over there. （变一般疑问句） →Are there any boys over there?5)There be句型和have/has的区别：There be 表示某物存在于某个地方， have/has表示某人拥有某一样东西。例如：There is a book on the desk.书桌上有一本书。
I have a book. 我有一本书。二者有时也可以通用，表示"某物本身拥有…。
