There be句型
考点一 基本用法
1.There be句型主要用来表达“某地或某时有某人或某物”，其基本句型为“ There be+某物/某人+某地某时”，其中 there没有实际意义；be是谓语动词；“某人或某物”做句子的主语；“某地或某时”做句子的状语，一般是介词短语。
There is a ftball under the chair.椅子下面有个足球。
2.There be句型中的be动词在人称和数上应与其后的主语保持一致。主语是不可数名词或可数名词单数时用is，是复数时用are。
There is a flwer in the bttle.瓶子里有一朵花。
There are sme bks in the backpack.背包里有些书。
3.There be句型的否定结构在is/are后面加nt，一般疑问句把is或are放在there之前，肯定回答“Yes, there is/are.”，否定回答“N,there isn't/aren't.”。如果肯定句中有sme，否定句和疑问句一般要改成any。
There aren't any children n the playgrund.操场上没有一些孩子。
—Is there a bank near here？在这附近有银行吗？
—Yes,there is.是的，有。/N,there isn't.不，没有。
There are sme children in the picture.照片里有一些孩子。
There aren't any children in the picture.照片里没有一些孩子。
考点二 特殊用法
1.若句子中有几个并列的主语时，be动词要与离其最近的一个主语在人称和数上保持一致。（就近原则）
There is a by,a girl and tw wmen in the huse.房子里有一个男孩、一个女孩和两个妇女。
There are ten students and a teacher in the ffice.办公室里有十个学生和一个教师。
2.“There be+名词或代词+动词-ing形式”意思是“有某人或某物正在做……”。
There are sme teachers playing basketball n the playgrund.有些老师正在操场上打篮球。
3.There be句型的一般将来时的肯定结构为“There will be+名词+其他成分.”或“There is ging t be+名词+其他成分.”，意为“将要有……或“将举行……”。（注意：不论be后的名词是单数还是复数，be不能写成is/are）
There will be a meeting tmrrw mrning.明天上午有个会议。
考点三 难点突破
There be句型与 have/has都可以意为“有”，但它们的含义不同。There be句型表示的是“存在关系”，而 have/has表示的却是“所有关系”，have/has的主语一般是人，有时也可以是物。
There is a car in frnt f the schl gate.学校门前有辆小汽车。（强调车在门前）
I have a car.我有一辆小汽车。（强调车归我所有）
注意（1）如果这两个表示“有”的句型中含有sme，改为否定句或疑问句时sme要改为any。
There is sme water in the glass.杯子里有一些水。
→ There isn't any water in the glass.杯子里没有水。
（2）表示“构成”关系时，have/has与 There be结构常常表示相同的意思，可以进行同义句转换。
A week has seven days.
=There are seven days in a week.一周有七天。
一.用括号内所给词的适当形式填空
1.There (be) fifty bks here.
2.There (be) sme water in the glass.
3.There (be) a lt f apples n the table.
4.There (be) an ld building in frnt f ur schl.
5.There (be) sme cups f tea n the table.
二．.按要求完成句子,每空一词
1.There is a library acrss frm the schl.(改为否定句)
a library acrss frm the schl.
2.There are sme birds in the tree.(改为一般疑问句)
birds in the tree?
3.Is there a baseball under the chair?(作肯定回答)
Yes, .
4.There are sme children in the street. (改为一般疑问句)
children in the street?
5.There is a cat under the tree.(改为一般疑问句)

三 设空处表示“拥有”,主语是I,故填have。
2.There is 设空处表示“存在”,用there be句型,be动词后面的名词是可数名词单数basketball,故be动词用is。
3.have 设空处表示“拥有”,主语是They,故填have。

答案详析
1.B根据2空后的“the sea water flws int peple's hmes and gardens”可知，海水流入了人们的家里和花园里，由此可知此处指现在斐济人民面临一个大问题。
2.A根据空后的“the sea water flws int peple's hmes and gardens”可知，海水流入了人们的家里和花园里；再结合常识可知，这是海平面上升造成的，故此处指海平面上升。g up“上升”，符合语境。7空后的sea levels rise也为提示信息。
3.C 根据上一句及空前的 they can't grw anything可知，因为气候变化海水进入了人们的家里，他们不能种植任何东西，故此处指人们不得不搬走。mve away“搬走”，符合语境。
4. A 根据空后的“but sme lder peple dn' like it”可知，许多老人不喜欢这么做；but表示转折，故此处指有些人很乐意离开他们的村庄。
5. D根据空后的“because they hpe t live in the village all their lives”可知，因为他们希望一辈子都住在村子里，故可知他们想留下来。
6.B 根据上文可知，海平面上升导致海水进入了人们的家里，人们不得不搬离。再结合常识可知，人们会搬到地势更高的地方来预防海水进入家里。故此处指2014年，一个村庄搬到了岛上一个地势更高的地方。
7.A 空后的“海平面上升”和空前的“人们离开他们的家园”构成因果关系，故选连词because。
8.C结合语境可知，此处指他们中的许多人仍然几乎每天回到他们的旧村庄。句子主语为sme f them，故此处应选their。
9.B 根据空前的“have t leave their village”可知，他们不得不离开他们的村庄；再结合空后的“new hmes in ther places”可知，此处指他们在其他的地方建造新的房子。

答案详析
1.G根据上一句可知，昆虫是很重要的，因.为它们是一些动物的食物；再结合下文介绍的昆虫的重要性可知，空处内容应与昆虫的重要性有关，故G项“如果没有昆虫，这些动物会没有东西吃”可承接上文，符合语境。
2. A 根据下一句“It says that the number f insects is falling.”可知，它表明昆虫的数量正在下降，此处的It指代的应是上一句提到的某个事物，故A项“这里有一项关于昆虫的新研究”可引出下文，符合语境。It指代选项中的a new study。
