英语七年级下Unit6Topic1 Our Local Area知识点讲解与练习

英语七年级下Unit6Topic1 Our Local Area知识点讲解与练习

Unit6 Our Local AreaTopic1 There is a study next to my bedroom一、语法精讲:there be句型总结1、there be句型表示某地有某物或某人,表示客观存在的这种状态,这里there是引导词,本身无词义,句中谓语动词be的人称和数量与其后的主语保持一致。

①肯定句:There is/are+人/物+地点(介词短语)如:There is a pen on the desk. There are some apples on the desk.翻译下列句子:那儿有一条狗在我书包里有一本英语书There be 是个近视眼,如果句中有多个名词并列时,be动词要与邻近的主语保持一致。

即就近原则:eg: There is a pen and some books in the pencil-box.There are some books and a pen in the pencil-box.用be动词的正确形式填空1.There______ a pen in my hand。

2.There______ some juice in the glass.3.There______ some books on the shelf.②一般疑问句:把be动词提前,句末加问号,肯定回答:Yes, there is/are. 否定回答:No, there isn’t/aren’t.如:Are there any pens in your bag? Yes, there is/are. No, there isn’t/aren’t.把下列句子别为一般疑问句There is some water in the glassThere is a bird in the tree.There are a few people in the classroom.③否定句:直接在be动词后加not. 当肯定句中有“some”时要改为“any”There is some milk at home.------- There isn’t any milk at home.把下面句子改为否定句There is 50 students in our class.There are some bananas in the kitchen.There is some water in the bottle.④there be句型的特殊疑问句A:对there be句型中的主语提问,当主语是人时,用“who’s+介词短语”当主语是物时,常用“what’s + 介词短语”,注意:主语无论是单数还是复数,be动词都用is,且省略there (回答时却要根据实际情况) 如:There is a little girl in the room.------- Who is in the classrrom?There are two desks in the room.------ What’s in the room?B:对数量提问用How many或how much语序:How many/much +be+there+地点(介词短语)?如:There are ten oranges in the basket.----How many oranges are there in the basket?There is some milk in the bottle.----------How much milk is there in the bottle.C:对地点状语进行提问,用“where is/are+ 主语”There is a computer on the desk.------ Where is the computer?There are 4 students in the classroom--- Where are the 4 students?划线部分提问练习题1.There are 5 bikes in my house.(对划线部分提问)2.There is an English book on the desk.(对划线部分提问)3.There is a cat in the garden.(对划线部分提问)4.There are few people in the bus.(对划线部分提问)2.There be 句型与have、has的区别:①have、has表示“某人或某物有…….”强调的是拥有,即某物或某人与主语是所属关系。
