二．重点单词和短语

1. There be句型

(1)结构：There be+sb./sth.+地点表示“在某地有某人或某物”（there是引导词，没有词义；be是谓语动词；某人/物是主语，地点作状语，多为介词短语）

E.g. There is a bank in the neighborhood.

(2)There be句型的谓语动词be在人称和数上应以后面的第一个名词保持一致。

▲如果后面的名词是可数名词单数或不可数名词，谓语动词用is.

E.g. There is some salad on the table.

▲如果后面的名词是可数名词复数，谓语动词用are.

E.g. There are some students in the classroom.

▲如果There be句型中有多个名词，be动词通常与第一个名词保持人称和数的一致。

E.g. There is a boy and two girls in the room. There are two girls and a boy in the room.

(3)There be句型的一般疑问句：将be动词提到句首。

→Are there any students in the classroom?肯定回答：Yes, there is/are.否定回答：No, there isn’t/aren’t.

E.g. —Is there a bank near here?—Yes,there is./No,there isn’t.

(4)There be句型的否定句：在be后加not

E.g. There is a post office near hear.→There isn’t a post office near hear.

(5)There be句型的特殊疑问句：特殊疑问词（组）+be +there +其他

E.g. There are three pens in my schoolbag.(请对划线部分进行提问).

→How many pens are there in your schoolbag?

【拓展】there be和have 都表示“有...”，但有所区别：

①含义不同。

there be 结构表示的是“某地有某物/人”，强调“存在关系”；

have则表示“某人/某物所有”，强调“所属关系”。

E.g. There is a bus in our factory. Our factory has a bus.

②句型不同。

there be 结构的句型为“There be +某物/某人+某地”，

否定句是把not放在be 之后，疑问句是把be提到句首；

have句型为“某人/某物+ have/ has +某物/某人”，否定句通常是在have前加don’t ( has前加doesn’t )，疑问句是在句首加do（第三人称单数加does）。

E.g. There isn’t a cat under the chair.

She doesn’t have two brothers.

③用there is或there are还是用have或has均取决于句子的主语。但there be 句型里有两个或多个并列主语时，be习惯上和最靠近的那个在数上保持一致。

E.g. There is a bike under the tree. There are some bikes under the tree.

There is an apple and two oranges on the table.

You have a new book./ You have some new books.

He has a new book./ He have some new books.

④当表示某物的构成和组成部分时，用there be 和have均可。

E.g. Our school has twenty classes. (= There are twenty classes in our school.)

2. across from 意为“在……的对面”，后面接表示地点的名词或代词。

E.g. We live across from the street. There is a bank across from the library.

表示“在……的对面”的短语还有：

①on the other side of... The bus stop is on the other side of the river.

②be opposite to... The fruit shop is opposite the post office.

3、next to表示“在...旁边；靠近；紧挨着”，后接表地点的名词或代词。

E.g. The pay phone is next to the library. The garden is next to my house.

【辨析】near也表示“在...旁边”，但与next to有所区别：

从空间上讲，near只表示“在...旁边；在...附近”而next to有“紧挨着”之意；也就是说next to比near 靠的更近。试比较：

E.g. Peter sits next to Mike. Peter sits near Tom.

4.【辨析】between和among

▲between 表示“在....中间”，常与and连接，构成短语between....and.....，指在两者之间
