一、Sentence 1: I have a book.

Sentence 2: There is a book on the desk.

引出：There be 句型

表示某地存在某物，表示客观存在这种状态，但物体的主人并不清楚，意为“有、存在”，句中be动词应与其后的主语的数保持一致。

二、There be 句型的肯定句的两种基本句型：

1. There is +主语（a/an+单数名词或不可数名词）+地点状语

Eg: There is a box in my schoolbag.

There is some water in the bottle.

2.There are+主语（可数名词的复数）+地点状语

Eg: There are some chairs in the house.

自我检测：

Fill in the blanks with “is/are”

1.There____ a pen in my hand.

2. There____ some juice in the glass.

3.There____ some books on the shelf.

(学生自主完成——展示——纠错——教师精讲)

Step 2 Exploration(探究)

一、比较句子：

1.There ____ a ruler、two pictures and an eraser in my box.

2.There ____ two pictures、a ruler and an eraser in my box.

注意：

在There be句型中，当有多个名词并列做主语的时候，be动词要与最邻近的主语的数保持一致，即就近原则。

Eg:There is a chair、two desks and a clock in my classroom.

二、合作探究

结合含有be动词的一般现在时的否定句、一般疑问句的结构，完成下面的句子：

There is some water in the cup.

→There____ ____ water in the cup.(否定句)

→____ ____ ____ water in the cup?(一般疑问句)

肯定回答：Yes,there is/are

否定回答：No,there isn＇t/aren＇t
