中考复习之There be句型的用法 教学目标: 能力目标:1.了解there be 句型的基本信息。掌握四会句型。知识目标:强化 there be 句型的各种句子形式。情感目标:了解“存在”和“拥有”的区别。教学重难点:重点:熟记there be 句型的各种句子形式及运用。难点:1、掌握四会句型。2、强化there be 句型的特殊疑问句及答语,就近原则句子中be动词的单复数的运用。教学准备:1、纸质练习题。2、PPT 复习内容:熟记there be 句型的各种句子形式及运用。 教学步骤:Step 1(一)、定义: There be 结构主要用以表达 “某地有某人(某物)”。其基本句型为“There be + 某物或某人(主语) + 某地”。(二)、be动词的选择: There be 结构中的谓语动词be(is / are)在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词用is ;主语是复数时用are。 (三)、具体结构:(1) There is + 单数可数名词/不可数名词+ 地点状语. E.g. There is a pear in the basket. E.g. There are 3 pencils in the box. 盒子里有三只铅笔。 巧计语法: “有”字放前面,有“啥”放中间; 时间地点放后面;单数is, 复数are 注意be的两变化。 (四)句型变化: (1)、否定句:there be的否定式通常在be后加not。 E.g. There is a ball under the tree. 树下有一个球。 There isn't a ball under the tree. E.g. There are six boys in the classroom。教室里有六个男孩。 There aren't six boys in the classroom.
(2)、一般疑问句及其答语: 1、一般疑问句:把be动词提前,首字母大写,句末用问号即可。 2、回答时,“用什么问,就用什么答”,用Is / Are there来问,就用there is / are来回答。 肯定回答:Yes, there is / are. 否定回答:No, there isn't / aren't. E.g. 1、There are eight birds on the sofa. → Are there eight birds on the sofa? Yes, there are. / No, there aren't. . 2、There is a cup on the table . → Is there a cup on the table . Yes, there is. / No, there isn't.课堂练习:1. There is a student and a teacher in the classroom .否定句 一般疑问句 否定回答 (五)、some和any在“there be”句型中的用法: 1 ). some 一些(some用于肯定句) 2 ). any 一些(any用于否定句和一般疑问句) 注意:There be句型在变成否定句或一般疑问句时,要注意把句中的some变成any。 E.g.1、There is some milk in the glass.→ There isn't any milk in the glass.(否定句) Is there any milk in the glass?(一般疑问句) 2、There are some women on the playground. → There aren't any women on the playground. . (否定句) Are there any women on the playground?(一般疑问句)课堂练习:1. -- Are there _____ banks behind the park? -- No, there are _____ banks behind the park. A. some, not B. some, any C. any, not D. any, no 2.There is a book in the bag.(变为否定句) (六)、就近原则: 若句子中be动词后有两个或两个以上并列的名词作主语时, be动词的形式要与离其最近的一个主语在人称和数上保持一致。 E.g. 1.There is a box, two pens and some erasers on the desk. 书桌上有一个盒子、两支钢笔和一些橡皮擦。 2.There are two boxes, a pencil and some erasers on the desk. 书桌上有两个盒子、一支铅笔和一些橡皮擦。3.There some erasers ,two boxes and a pencil on the desk. 书桌上有一些橡皮檫、两个盒子和一支铅笔。课堂练习:There milk and eggs on the table .在桌子上有牛奶和鸡蛋。 There eggs and milk on the table. (七)、“there be” 和 “have”的区别 There be结构和have都表示“有”,但用法不同。(1)there be结构强调客观存在,表示“某处有(存在)某人/物”。(2)have强调所属关系,表示主语“拥有”。(3)There be 句型表示“存在”关系,have表示“所属”关系,两者不能混在一个句子中。Eg:There is a watch under the tree.(表示某处有(存在)某物) I have a watch .我有一块手表。(表示某人拥有某物)(八)、there be 句型的一般将来时态有两种形式:(1)a.there is going to be 指已计划或打算好的,“be”不变化,但is会随着人称,数和时态的变化而变化。此句可理解为:Something is going to be there.(2) there will be 指“临时决定的” be 是不变化的。此句可理解为:Something will be there.(3) There is/are going to be 或There will be 其否定形式是在is /are/will后加否定词not; 一般疑问句是直接把is/are/will提到句子开头。a. 肯定回答:Yes,there is/are或Yes,there will。b. 否定回答:No, there isn’t/aren’t.或No,there won’t.Eg: a). There is going to be a sheep on the farm.→Is there going to be a sheep on the farm?There is not going to be a sheep on the farm.b). There will be an egg on the plate.→Will there be an egg on the plate?There will not be an egg on the plate. (九)、含有there be结构的反意疑问句 如果陈述部分为there be结构时,则疑问部分用be(not)there或will not there 。例如: a).There is not much news,is there?b). There will be a new hospital nearby, won’t there? 这 附近要建一家新医院,是吗?(十)、 there be句型的特殊疑问句形式有以下三种变化: 对主语提问:a). 当主语是人时,用“Who’s+介词短语?”b). 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). 对地点状语提问:提问地点当然用“Where is / are+主语?” 对数量提问:一般有两种句型结构:a). How many+复数名词+are there+介词短语?b). How much+不可数名词+is there+介词短语?Eg: How many books are there in the bag ? How much bread is there in your bowl ?最后总结巧计语法:There be结构表存在,记清be有四时态,肯疑否反特明白,三词两句可互换,就近原则动名带,have所属是关键。 Step2 中考链接:一.单选题 1. ______ there a radio on your desk? A. Are B. Is C.
