否定句：There + be + not + 主语 + 地点状语

特殊疑问句：How many/much + 名词 + be + there + 地点状语？

不可数名词 没有复数形式 不与a/an直接连用 可与much, little, some连用 4. 表示数量时需用单位词 water, air, sunlight, soil, rice, wheat（指谷物时）

六、易错点提醒
1. There be句型与have/has的混淆：
There be 表示“某处有某物”（存在关系）。
have/has 表示“某人/物拥有某物”（所属关系）。
错误：There have a tree in the garden.
正确：There is a tree in the garden. 或 The garden has a tree.
2. 可数与不可数名词的修饰词误用：
错误：There are much trees.
正确：There are many trees.（trees可数）
错误：The plant needs many water.
正确：The plant needs much/a lot of water.（water不可数）
3. leaf, life等名词复数形式不规则：
leaf → leaves（去f加ves）
life → lives
错误：The tree has many leafs.
正确：The tree has many leaves.
4. How many与How much的混淆：
How many + 可数名词复数：How many flowers
How much + 不可数名词：How much sunlight
错误：How much trees are there
正确：How many trees are there
5. 情态动词后接动词原形：
错误：Plants can makes food.
