初中英语重要句型:否定前移

Ithink..意为“我认为...”是对某人或某事的看法或态度的一种句型。

其否定式常用I don't think...Idon't think+肯定句 我想....不

eg.l don't think l' ll take it.(我想我不买它了)

请注意:翻译成中文意思否定在从句中，但是英语的表达否定在主句中。

宾语从句否定前移满足三个条件:

1.主句主语为第一人称(l,we)2.主句为一般现在时3.主句谓语用来表达观点，推测等词

(believe,suppose ,think,imagine,consider,expect )

初中英语句型There be结构

There be 结构 There+ be+主语+地点状语/时间状语

(1)这是英语中常见的一种结构，表示“某地有某物其含义为“存在;有”

如:There are twenty girlsin our class.

have与there be的区别have的含义是“所有,拥有”其主语一般为人.

eg.l have a nice watch.

(2)There be结构中的 be动词的单复数形式由后面挨近的一项的单复数决定，即就近原则。

There is a river near ourschool.否:There is not a river nearour school.

问:ls there a river near our school?

回答: Yes, there is.No there isn't.

There are many riversnear our school.

(3)there be 结构的一般将来时,同学们较难掌握,其正确形式为: there is goingto be 或 there will be.

There is going to be ameeting next week.

(4)反意疑问句的构成:There is no water in theglass, is there?
