四年级上册英语《Unit 4 When do you have classes Unit 4 When do you have classes（通用）》精品课教案

e.g There is a book on the desk.

桌子上面有一本书。

结构：There be +主语（某人/某物）+地点状语

e.g There is some water in the bottle.

二． Be 的确定。

be （is/ are ）其中is +可数名词单数或不可数名词，are +名词复数。

e.g 1.There is a boy under the tree.

树下面有一个男孩。

2. There is some milk in the fridge.

冰箱里有一些牛奶。

3. There are some flowers in the garden.

花园里有一些花

温馨提示：

若句子中有几个并列主语时，be 动词的形式要与离其最近的主语在人称和数上保持一致，也就是所谓的就近原则。

e.g 1. There is a dog and two cats under the tree.

2. There are two cats and a dog under the tree.

三．There be 与have /has 区别

There be 句型强调“某处有某人/某物”,着重“存在”，have/has则强调“某人拥有某物”，注重“拥有”。

e.g 1.我家里有四个孩子。

There are four children in my family.

2.我有两个孩子。

I have two children.

四． 一般疑问句

方法：把be 提前，放于句首，如果句中有some ,则some变any.

肯定回答：Yes .there is /are.
