-How many classrooms are there in our school?我们学校有多少间教室?
-There are24 classrooms.有24间教室。

【例句】(1)-How many bowls are there on the table 桌子上有多少个碗?
-There is only one.只有一个。
(2)-How many computers are there in the computer room 电脑室里有多少台电脑?
-There are fifty.有五十台。

Are there any computer rooms 有电脑室吗?
解析:句型“Is/Are there. ”为there be句型的一般疑问句句式,用来询问某地是否存在某(些)人或某(些)物(品),其肯定回答为“Yes,there is/are.”,否定回答为“No,there isn't/aren't.”。将there be句型的陈述句改为一般疑问句,先将be动词移至句首,如果原句中有some,要将some改为any;如果原句中有I/we,my/our,me/us,则要将I/we,my/our,me/us分别改为you,your,you。

易错易混全解
易混淆基数词与序数词的用法。
【例题】根据中文提示,完成句子。
(1)那个园子里有两只大猩猩。
There are gorillas in the garden.
(2)在第二个园子里的那只动物是一只大猩猩。
The animal in garden is a gorilla.
【答案】(1)two (2)the second
点拨:基数词前面一般不加the,后接可数名词复数(除one以外),而序数词前一般要加the,后接可数名词单数。第(1)小题,“两只”指的是大猩猩的数量,没有强调顺序,所以设空处应该用基数词,故填two。第(2)小题,“第二个”强调园子的顺序,故填the second。
易混淆there be句型与have/has的用法。
【例题】单项选择。
( ) some bees among the flowers.
A.There have B.Have C.There are
【答案】C
点拨:there be句型与have/has都译为“有”,但there be句型表示某地存在某(些)人或某(些)物(品),强调存在性,而have/has为动词,表示拥有某(些)物(品),强调所属关系。本题句意为“花丛中有一些蜜蜂”,主语some bees和the flowers之间不属于所属关系。故选C。
易混淆“It's time for”与“It's time to..”的用法。
【例题】按要求完成句子。
It's time for the birthday cake.(改为同义句)
It's time the birthday cake.
【答案】to have/eat
点拔:向型“It's time for”意为“是…的时候了”,相当于“It's time to”,两者的区别在于:It's time for后接名词,而It's time to后接动词原形。故填to have/eat。
