一、选择题
1.首先观察题目本身的提示tonight，判断该题的时态是将来时，首先排除选项Ａ和Ｄ。Ｃ选项的结构不正确，故选Ａ。
2、首先观察题目本身的提示just now，判断该题的时态是一般过去时，首先排除选项Ａ和Ｂ。Ｃ选项是复数，不符和题意，故选Ｄ。
3、首先观察题目本身的提示now，判断该题的时态是一般现在时，首先排除选项Ｄ。选项B为原形不正确，排除。虽然原句中的主语是a pen and two books，但是根据就近原则，离there be 最近的是a pen，选项Ａ为复数形式，排除。故选Ｃ。

There be 句型的用法：表示某个地方存在某物或某人，Be动词的单复数必须依主语的变化而变化。(单数is 复数are )
eg：There is a table in the room. 房间里有一张桌子。
There are some birds on the tree.树上有很多鸟。
一、 There be 句型的结构：
1.常见句型结构
（一）There is+单数可数+地点状语
eg：There is a ruler on the desk. 书桌上有一把尺。
（二）There are+复数主语+地点状语
eg：There are four apples on the tree. 树上有四个苹果。
There are some flowers in the park. 公园里有许多花。
（三）there is + 不可数名词 +地点状语 （即使有some 也是 单数）
eg：There is some water in the bottle. 瓶子里有一些水。 （水是不可数名词）
2. There be选择就近原则：
3
There be句型的就近原则是There be句型中语法项目的重点考点。There be句型中be动词的单复数形式由最挨近的一项的单复数决定。
如：There is a pen, two books and many pencils on the desk.
(在本句中尽管有钢笔、书和铅笔，但是由于离be动词最近的一项是单数a pen，因此，be动词用单数is。)
二、There be 句型的疑问句及回答
（一）There be 句型的疑问
1. 在“There is/are...”的疑问句中,要把Be动词放在there之前,并将句号变问号。难点:句中出现的some要改成any。
2. 肯定回答为：Yes, there is/are.
3. 否定回答为: No, there isn’t/aren’t.
eg: 可数名词单数1. 肯定句There is an apple on the tree.
疑问句 Is there an apple on the tree?
肯定回答: Yes, there is. 否定回答: No, there isn’t.
可数名词复数2. 肯定句There are five pens on the desk.
4
疑问句Are there five pens on the desk?
肯定回答: Yes, there are. 否定回答 No, there aren’t.
不可数名词的时候 3.肯定句 There is some water in the cup. （水是不可数名词）
否定句 Is there any water in the cup?
肯定回答: Yes, there is. 否定回答: No, there isn’t.
（二）There be 句型的特殊疑问句：
There be句型的特殊疑问句形式有以下三种变化：
① 对主语提问：当主语是人时，用\\\"Who\\'s+介词短语?\\\"；
当主语是物时，用\\\"What\\'s + 介词短语?\\\"。
（注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。）
② 对地点状语提问：提问地点用\"Where is / are+主语?\\\"
③对数量提问：一般有两种句型结构：
How many+复数名词+are there+介词短语？
5
How much+不可数名词+is there+介词短语？
eg:How many people are there in the picture?
How much water is there in the bottle ?
三、There be 句型的否定形式
There be 句型的否定： 否定形式只要在be动词后面加not即可，is not are not= aren’t
但要注意的是句中如果出现some则改成any.
1.There is a knife in the kitchen.
——否定:There is not a knife in the kitchen.
2.There are five apples on the tree.
—— 否定:There are not five apples on the tree.
3.There is some water in the bottle.
