U3 there be 句型与练
There be 句型
1. 定义：There be句型表示某处存在某物或某人。

2. 结构：
There is+第三人称单数可数/不可数名词+地点状语
例：There is a ruler on the desk. 书桌上有一把尺。

There is some water in the bottle. 瓶子里有一些水。

There are+复数名词+地点状语
例：There are four apples on the tree.树上有四个苹果。

There are many flowers in the park.公园里有许多花。

there是引导词，在句中不充当任何成分，翻译时也不必译出。

注意：句子的主语是某人或某物，谓语动词be要与主语（某人或某物）的数保持一致。

当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。

eg. ① There is a bird in the tree. 树上有一只鸟。

② There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。

③ There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。

3. There be句型与have的区别：
(1) There be 句型和have都表示“有”的含义。

区别如下：There be表示“某处存在某物或某人”；have表示“某人拥有某物/某人”，它表示所有、拥有关系。

①He has two sons. 他有两个儿子。

②There are two men in the office. 办公室里有两个男人。

(2)当have表示“包括”、“存在”的含义时，There be 句型与其可互换。

eg. A week has seven days. =There are seven days in a week. 一个星期有七天。

4. There be 句型转换
have，has
一．1．表示：某人或某物“拥有”什么东西，强调“所属关系”，而且某人某物作为句子的主语。

2．have用在人称I，we，you，they和复数的人或物后面。

has用在人称he, she, it和单数和人或物后面。

I have a daughter. He has a lucky dog.
二、have的搭配
1．“have ＋表示一日三餐的名词”，意为“用餐”。

如：have breakfast
吃早餐，have lunch吃午饭，have supper吃晚饭。

2．“have ＋表示食品、饮料等名词”，意为“吃；喝”。

如：have (some) bread 吃面包，have eggs (for breakfast) (早餐)吃鸡蛋，have (a cup of) tea 喝(一杯)茶。

3．“have ＋表示动作的名词”，没有固定的意思，常与表示动作的名词同义。

如：
have a rest 休息一下have a swim 游泳have a drink (of．．．)喝一点(……)
have a look (at ．．．)(朝……)看一眼
4．“have ＋表示某种活动的名词”，意为“进行，举行”。

如：
have a class (学生) 上课have a birthday party 举行生日聚会
三、have/ has的用法：
1) 谓语动词have表示“有”，有两种形式：have和has，前者用于第一人称(I, we)，第二人称(you)和第三人称复数(they)，后者用于第三人称单数(he, she, it)或单数名词。

I have an apple and he has two bananas. You have a new English teacher.
It has two big eyes. Julie and Jack have a nice car.
2) have/has句型与there be句型的比较：两者都表示“有”，但用法不同。

前者表示所属关系，即表示“某人或某物有什么”，而后者表示存在，表示“某地有什么”。

She has a lot of pretty skirts. There are a lot of pretty skirts in the shop.
3) have/ has的否定句，一般要加助动词do/ does，再加not构成，即do not have (don’t have)/ does not have (doesn’t have)
She does not have a sister. We don’t have any classes on Saturday. 我们星期六没有课。

Ann and I don’t have a big room. 我和安没有一个大房间。

4) 一般疑问句由“助动词Do/ Does + 主语+ have + 宾语”构成，回答用Yes, … do/ does.或者No, … don’t/ doesn’t.
--Do you have a big house? 他们的房子大吗？--No, they don’t. 不，他们的房子不大。

--Does he have an eraser? 他有橡皮吗？--Yes, he does. 他有的。

Step 1 It is +adj. +动词不定式的用法
------------------------------------------
I. It is + adj. + to do something结构
句中it是形式主语，真正主语是动词不定式to do something。

因此也可以表达为to do something + is +adj.。

e.g. It is amazing to drive past fields which seem to go on forever or whole hills covered with neat rows of grapevines。

本句形式主语为it。

真正主语to drive…grapevines移到了句子后部，使句子变得平稳，不致主语太长。

如果把真正主语放在前面，那么整个句子就显得头重脚轻。

因此，就用it 作为先行主语。

这种结构还有两种动词不定复合结构。

1. It is + adj. + for somebody to do something
e.g. It was very difficult for them to fly because men have not got wings.
此句真正的主语是动词不定复合结构for them to fly。

其中them是to fly的逻辑主语。

2. It is + adj. + of somebody to do something
e.g. It is sensible_____ you to bring an umbrella in such weather.
A. in
B. for
C. with
D. of
答案为D。

这里sensible跟逻辑主语you的关系是表达人的特点、性格、本质等。

像此类形容词还有kind, foolish, clever, wise, friendly等。

II. It is +名词+ to do something结构
e.g. It is great fun to see the pandas walking in the zoo.
III.另外, it作先行主语时还有其他用法
1. it +及物动词+宾语+不定式
e.g. It cost me 100 dollars to repair the car.
It takes me two hours to finish my homework every day.
It gave me great pleasure to watch them.
2. it + be +名词/形容词+ doing
e.g. It is no use studying for an exam at the last minute .
It is a waste of time talking to him.
It is pleasant sitting here.
