【讲练结合】五年级上册英语Unit 2 A new student语法划重点
1. 语法精讲
(一)there be 结构
01. There be句型变一般疑问句,be动词提至句首,句尾加问号。
Is there an apple on the table? (Yes, there is. No, there isn’t)
Is there any milk in the glass? (Yes, there is. No, there isn’t)
Are there any apples on the table? (Yes, there are. No, there aren’t.)
注:在There be句型中,some用于肯定句,any用于否定句和疑问句中。
02. and和or在there be句型中,and用于肯定句,or用于否定句。
There is a ruler, an eraser and a pen on the desk. 书桌上有一把直尺, 一块橡皮和一支钢笔。
There is not a ruler, an eraser or a pen on the desk. 书桌上没有一把直尺, 一块橡皮和一支钢笔。
03、There be句型的就近原则。当主语是两个或两个以上的名词时,谓语动词要跟它最近的那个名词的数保持一致。
There is a book and some pens on the floor.
There are some pens and a book on the floor.
