原七年级英语下册 Unit 8 Is there a post office near here（第3课时）(Grammar Focus3c)同步语法精讲精练课件 （新版）人教新目标版

第三课时(Grammar Focus3c)单元同步语法精讲精练定义：there be句型也称为“存在句”，表示“某地有某物”。用法及构成there be句型结构为：There be名词(主语)地点副词/介词短语(表示地点)。there be句型属于倒装句，主语通常放在谓语后面，动词be为谓语。be动词应根据主语的单复数而变化，主语是单数，用there is；若主语是复数用there are，若主语是不可数名词，则用there is。eg：There are 50 students in our class.我们班有50个学生。there be句型中的谓语应和后面的主语保持一致，若有两个或两个以上的主语，动词be的形式应由和它位置最近的那个主语的人称数决定。即遵循“就近原则”。eg：There is a pen and two books on the desk.桌子上有一支钢笔和两本书。There are two books and a pen on the desk.桌子上有两本书和一支钢笔。there be句型的否定句，直接在be动词后加not；其一般疑问句，要将be动词放在句首。肯定回答为Yes，there is/ are；否定回答为No，there isnt/ arent。【注意】若there be句型的否定句和一般疑问句中有some时，则应将some改为any。There be句型一般现在时的特殊疑问句由“特殊疑问词主语is/ arethere地点状语”构成，有时地点状语可省略。答语不能用Yes或No，需根据情况直接回答。eg：How many apples are there in the bag？包里有多少苹果？Five.五个there be与have/ has的区别there be结构表示客观存在，意为“某地有某物(人)”；have/ has表示所属关系，意为“某人拥有某物”。eg：There is a TV in our classroom.在我们的教室里有一台电视机。We have a TV in our classroom.我们有一台电视机在教室里。next to 紧挨着，与相邻near 在附近behind 在后面across from 在对面in front of 在的前面(范围之外)【拓展】in the front of 在的前面(范围之内) 一、用be动词的适当形式填空。(必要时可加not)1There _a pay phone near here.2_there any books in the bag?No，there _3There _an apple and two books on the desk.4_there an English boy in the room?Yes，there _5There _some food in the kitchen.isArearentisIsisis二、从方框中选择合适的词或短语完成句子。6The post office is across _the bookshop.7My school is _Bridge Street.8Is there a hotel _here?9The pay phone is _the bank.10The park is _the restaurant and the supermarket.fromonaroundnext_tobetween三、按要求完成下列句子。11There are some apples on the tree.(改为一般疑问句)_apples on the tree?12There are some trees near the house.(改为否定句)There _trees near the house.13Are there any new storybooks on the bookshelf(书架)？(作否定回答)_ Are there anyarent anyNo，there arent
