表示某個地方存在某物或某人，be動詞的單複數必須依主語的變化而變化。牢記以下決口，there be 句型就變的很簡單。
there be 有特點，單數不可數用is，複數主語用are。
否定be後把not填，疑問提be there前，
疑否some any換，單數複數就近選。
一、 There be 句型的結構：
1.常見句型結構
（一）There is+單數可數+其他
eg：There is a ruler on the desk. 書桌上有一把尺。
（二）There are+複數主語+其他
eg：There are four apples on the tree. 樹上有四個蘋果。
There are some flowers in the park. 公園裏有許多花。
（三）there is + 不可數名詞 +其他 （即使有some 也是 單數）
eg：There is some water in the bottle. 瓶子裏有一些水。（水是不可數名詞）
2. There be選擇就近原則：
There be句型中be動詞的單複數形式由最挨近的一項的單複數決定。
如：There is a pencil, three books and many pens on the desk.
(解析：在本句中儘管有鉛筆、書和鋼筆，但是由於離be動詞最近的一項是單數a pencil，因此，be動詞用單數is。)
二、There be 句型的疑問句及回答
（一）There be 句型的疑問
1. 在“There is/are...”的疑問句中,要把Be動詞放在there之前,並將句號變問 號。
難點:句中出現的some要改成any。
2. 肯定回答爲：Yes, there is/are.
3. 否定回答爲: No, there isn’t/aren’t.
eg：可數名詞單數
肯定句There is an apple on the tree.
疑問句 Is there an apple on the tree?
肯定回答: Yes, there is.
否定回答: No, there isn’t.
eg：可數名詞複數
肯定句There are five pens on the desk.
疑問句Are there five pens on the desk?
肯定回答: Yes, there are.
否定回答 No, there aren’t.
eg：不可數名詞的時候
肯定句 There is some water in the cup. （水是不可數名詞）
否定句 Is there any water in the cup?
肯定回答: Yes, there is.
否定回答: No, there isn’t.
三、There be 句型的否定形式
否定形式只要在be動詞後面加not即可，
is not =isn’t ；are not= aren’t
但要注意的是句中如果出現some則改成any.
1.There is a book in the school.
——否定:There is not a book in the school.
2.There are six birds in the tree.
—— 否定:There are not six birds in the tree.
（外來物在樹上用介詞 in ）
3.There is some water in the bottle.
——否定:There is not any water in the bottle.
4.There are some pears on the tree.
——否定:There are not any pears on the tree..
（樹上生長的用介詞on）
