句型:

1、一般疑问句

可以直接用yes或者no回答的疑问句叫做一般疑问句。

陈述句改一般疑问句的方法:

(1)先找出句子中的be动词(am,is,are)、助动词(do,does,did)、情态动词(can,should,must,would等),将它移到句子最开头,首字母大写。

(2)其它部分顺序不变,直接照抄。

(3)句末打上问号。

一般疑问句的回答:

肯定回答:Yes,主语+be动词/助动词/情态动词(跟主语配套)

否定回答:No,主语+be动词/助动词/情态动词(跟主语配套)+not

2、there be句型

(1)意义

There be 是英语中常用句型,意思是“有”,表示“人或事物的存在”。There在此结构中是引导词,已经没有副词“那里”的含义。There be 后面的名词是句子的主语,属倒装结构。疑问句形式是将be或will/have/can/must等助动词、情态动词提至there之前,否定形式则直接在be或助动词、情态动词后加not,因此要表达“某个地方或某个时间存在什么事物或人”的时候常用“There be + 名词+ 地点(时间)这一句型。

There are some sharks there.

Excuse me. Is there a repair shop near here for MP3?

There are lots of people there who can actually help you.

(2)结构

1、There be 句型中的be 应和其后出现的主语在数上一致,即“就近原则”,如:

There is a lamp on the table.

There are some apples in the bowl.

There are five books,two pens and a ruler in the school bag.

There is a ruler,two pens and five books in the school bag.

2、如果主语是复数名词,却表示一笔金额或一个总数或表达一个单个概念时,则仍用单数be形式,如:

There is five hundred dollars to pay.

There is still another 20 miles to drive.

There is duck and green vegetables for supper.

3、There be 中的be 有时可以是lie,stand,used to be,seem to be,appear to be 等,如:

There lies a river to the south.

There lived an old man in the small house.

There stood a temple near the river.

There used to be a castle at the foot of the hill.

(3)语法

主谓一致

1.当动词be后所接的名词是单数可数名词或不可数名词时,be 应该取单数is;当其后所接的名词是复数的可数名词时,be用复数are。

There's a man at the door.门口有个人。

There is some apple juice in the bottle.瓶子里有些苹果汁。

There are some strangers in the street.大街上有一些陌生人。

2.如果There be 后面是几个并列名词做主语时,动词be的形式和最靠近它的那个名词保持数的一致。

There is an ashtray and two bottles on the shelf. 架子上有一只烟灰缸和两个瓶子。There are two bottles and an ashtray on the shelf. 架子上有两个瓶子和一个烟灰缸。(4)时态

1.There be 句型中动词be可以有一般现在时、一般过去时、将来时和完成时。

There is no harm in trying.不妨一试。

There were fabulous wildflowers in the hills last spring.去年春天,山中有极美的

野花。

There will be a fine day tomorrow.明天将是一个晴天。

2.There be 句型可以和各种助动词、情态动词连用。

There may be a cigarette in that box.那只盒子里或许有支香烟。

There must be some cakes on the table.桌子上一定有些蛋糕。

There used to be a hospital there before the war.战前,那里曾经有家医院。

3.There be 句型也可以和这样一些的谓语动词连用:be going to 、seem to 、appear to 、used to、be likely to 、happen to ….

There seem to be a few trees between me and the green.在我与草坪之间好像有一些树。There is gong to be a meeting tonight.今天晚上有个会议。

There is likely to be a storm.可能有一场暴雨。

There happened to be a bus nearby.碰巧附近有辆公交车。

There appears to have been a nasty accident.似乎发生了一起严重事故。

4.there be 结构中除可以用be 外,还可以用其它动词。例如:

There came a scent of lime-blossom.飘来一阵菩提树的花香。

Once upon a time there lived a king in China.从前中国有一个国王。

否定句

1.There be 句型的否定句有两种构成方式,一种是将否定副词not放在be 之后,如:There isn’t a box in the room.房间里没有盒子。

There aren’t any pens on the desk.课桌上没有钢笔。

There hasn’t been any rain for a week.一周没下雨了。

There won’t be a meeting today.今天没有会议。

另一种是在主语前加上不定代词no , 如:

There is no water in the bottle.瓶子里没有水。

There are no pictures on the wall.墙上没有图画。

There will be no one at home tomorrow morning.明天上午不会有人在家。

There might be no money left。或许没有剩下什么钱。

疑问句

2.There be 句型的一般疑问句是将be 放在there 之前,回答时用yes或no,后接简单答语。如:

Is there a cake on the table?桌子上有块蛋糕吗?
