There be 句型與have, has的區別
一、There be句型
1．表示：在某地有某物或某人。
2．在there be 句型中，主語是單數或不可數名詞，be 動詞用is ；主語是複數，be 動詞用are ；如有幾件物品，be 動詞根據最近be動詞的那個名詞決定。
There is a book on the desk.
There is some water in the glass.
There are three men under the tree .
There is a bag,two books and three pens on the desk.
3．there be句型的否定句在be 動詞後加not , 一般疑問句把be動詞調到句首。
There is a duck in the river.
否定句：There is not a duck in the river.
一般疑問句：Is there a duck in the river?
4．some 和any 在there be 句型中的運用：some 用於肯定句， any 用於否定句或疑問句。5．and 和or 在there be句型中的運用：and 用於肯定句， or 用於否定句或疑問句。
5．針對數量提問的特殊疑問句的基本結構是：
How many + 名詞複數 + are there + 介詞短語？
How much + 不可數名詞 + is there + 介詞短語？
6．針對主語提問的特殊疑問句的基本結構是： What’s + 介詞短語？
二、have，has
1．表示：某人或某物「擁有」什麼東西，強調「所屬關係」，而且某人某物作為句子的主語。
2．have用在人稱I，we，you，they和複數的人或物後面。
has用在人稱he, she, it和單數和人或物後面。
I have a daughter. He has a lucky dog.
三、There be句型與have，has有時也可以通用。
如：The classroom has ten desks. = There are ten desks in the classroom. 教室里有十張桌子。
注意：
1．「have ＋ 表示一日三餐的名詞」，意為「用餐」。如：have breakfast吃早餐，have lunch吃午飯，have supper吃晚飯。
2．「have ＋ 表示食品、飲料等名詞」，意為「吃；喝」。如：have (some) bread吃麵包，have eggs (for breakfast) (早餐)吃雞蛋，have (a cup of) tea 喝(一杯)茶。

have a look (at ．．．)(朝„„)看一眼
4．「have ＋ 表示某種活動的名詞」，意為「進行，舉行」。
