There is some ink in the bottle. 瓶子里有墨水。 →否定:There is not any ink in the bottle.  三、There be选择就近原则: 重点考点:There be句型中,几个名词并列时,be的单复数形式由最近名词单复数决定。如:There is a pen, two books and many pencils on the desk. 本句中有钢笔、书和铅笔,离be最近的是单数a pen,因此,be动词用单数is。 四、There be 句型的疑问句及回答 (1) 一般疑问句 把be动词调整到句首,再在句尾加上问号即可。当肯定句中有some时,要改为any(否定变化也一样)。 There is some water on Mars.(火星上有一些水)→Is there any water on  Mars?(火星上有水吗?) There are some fish in the water.(水里有一些鱼)→Are there any fish in the water?(水里有鱼吗?)(二)There be 句型的回答  肯定回答:Yes, there is/are. 否定回答: No, there isn’t/aren’t.

There is a little girl in the room.(房间里有个小女孩)→Who is in the room?(谁在房间里?) 3. 对地点提问:提问地点用“Where is/are+主语”。 There is a computer on the desk.(桌子上有一台电脑)→Where is the computer?(电脑在哪里?)3.对数量提问: How many+复数名词+are there+地点短语? How much+不可数名词+is there+地点短语? There are two chairs in the bedroom.卧室里有两把椅子。 →How many chairs are there in the bedroom?卧室里有多少把椅子? 【典例】 (一)单项选择 1.There ________ a foreign teacher and some students talking about Chinese tea. A.has B.have C.are D.is 【答案】D 【详解】句意:有一位外教和一些学生在谈论中国茶。 考查There be句型。has有,第三人称单数形式;have有,动词原形;are是,用于第二人称单复数现在时,第一、三人称复数现在时;is是,用于第三人称单数现在时。根据题干“There…a foreign teacher and some students talking about Chinese tea.”可知是There be句型,不能与have/has连用,故排除选项A和B;There be句型需遵循就近原则,空后的“a foreign teacher”为单数,空处应填is。故选D。 2.Let’s save pandas! There ________ only about 2,000 pandas living in the forests now.

Thanks for telling me.
