Unit3My School语法(There be句型和方位介词)讲解与练习 第一部分 there be 句型完整语法梳理 一、核心含义 there be 句型表示某地存在某物/某人，强调 “存在有”； 区别于 have/has（表示人/事物拥有） 时态：本单元全部为一般现在时，动词只用 is /are 二、基础结构：就近原则（必考核心） 1. There is +单数可数名词/不可数名词+地点 主语是单数/不可数，be 动词用 is There is a whiteboard in your classroom. There is a teachers’ building across from the school hall. There is a student centre between the library and the gym. 2. There are +复数可数名词+地点 主语是复数名词，be 动词用 are There are some lockers in our classroom. There are some trees in front of the sports field. 3. 就近原则难点 如果后面并列多个物品，be 动词单复数看离它最近的名词： There is a desk and two chairs in the room.（靠近is的a desk单数→用is） There are two chairs and a desk in the room.（靠近are的two chairs复数→用are） 三、四大句型变换（肯定/否定/一般疑问 /特殊疑问） 1. 肯定句 There is +单数/不可数+地点. There are +复数+地点. 例句：There are some trees in front of the sports field. 2. 否定句：be后直接加 not is not = isn’t；are not = aren’t There isn’t a whiteboard in your classroom. There aren’t any lockers. 3. 一般疑问句：be 动词提前放句首 结构：Is there + 单数/不可数…? Are there + 复数…? 问答模板 1).—Is there a whiteboard in your classroom? —Yes, there is. / No, there isn’t. 2).—Are there any lockers? —Yes, there are. / No, there aren’t. 4. 特殊疑问句（对地点/物品提问） ① 对地点提问：Where + be +主语？ （课本配套问答，基础地点问答） Where is the library? It is behind the classroom building. Where are the bookcases? They are next to the window. ② 对物品数量/事物提问 What’s + 地点？（某地有什么） How many +复数名词+ are there +地点？（问可数数量） 四、限定词 some & any用法（高频考点） 1.some：用于肯定句，后接可数复数/不可数名词 There are some trees... 2.any：用于否定句、疑问句 Are there any lockers? / There aren’t any lockers. 五、易混易错点 1.there be 不与 have/has 混用 ❌ There has a book. ✅ There is a book. / He has a book. 2.主谓一致只看后面名词，不看地点 ❌ There are a pen on the desk. ✅ There is a pen on the desk. 3.in front of vs in the front of *in front of：在物体外部前面（树在操场前） *in the front of：在物体内部前部（黑板在教室前部） 4.回答 there be 问句，必须用 there，不用 it/they ❌ Yes, it is.（回答 Is there... 时错误） ✅ Yes, there is. 第二部分 方位介词 &方位介词短语讲解 （一）单个方位介词 1.behind 在…… 的后面 例句：It is behind the classroom building. 2.between 在（两者）中间，固定搭配：between A and B 例句：There is a student centre between the library and the gym. 3.under 在…… 正下方 例句：The ball is under the desk. 4.on 在…… 上面（物体表面相互接触） 例句：There’s a screen on the wall. （二）高频介词词组（考试必考） 1.next to 在…… 旁边，紧挨着 例句：They are next to the window. 2.across from 在…… 对面 例句：There is a teachers’ building across from the school hall. 3.in front of 在……（物体外部）前面 例句：There are some trees in front of the sports field. 4.in the front of 在……（物体内部）前部（拓展易混对比短语） 例句：The whiteboard is in the front of the classroom. 三、核心易混辨析（考试高频考点） 1. in front of VS in the front of in front of + 物体：在物体外面的前方 There are trees in front of the classroom. 树在教室外面前面。 in the front of + 物体：在物体内部的前部 The whiteboard is in the front of the classroom. 白板在教室内部前排。 2. between 固定搭配规则 between 只能用于两个事物之间，必须写 between A and B ❌ between the screen（错误，只有一个参照物） ✅ between the library and the gym（正确，两个建筑） 3. on the wall / in the wall on the wall：图画、屏幕、白板等贴挂在墙面表面 in the wall：窗户、门洞等镶嵌进墙体内部 四、做题判断小技巧 1.看到两个并列参照物（A and B）→ 优先用 between 2.物体紧贴相邻 → next to 3.一者在另一者后方 → behind 4.两者面对面、隔着空地 → across from 5.人/物在建筑物、场地外部前方 → in front of 6.物品贴在墙面、坐椅子 → on 7.物体垂直下方 → under 【综合练习题】 一、用所给单词的适当形式填空 考点：there be 单复数就近原则、is/are变形、some/any变换、方位介词搭配、 be 动词时态 1.There ______ (be) a big library behind the classroom building. 2.There ______ (be) some trees in front of the sports field. 3.______ (be) there a whiteboard between the two windows? 4.There ______ (be not) any lockers next to the door. 5.There ______ (be) two bookcases and a screen on the wall. 6.There ______ (be) a screen and two bookcases beside the window. 7.______ (be) there any students in the classroom now? 8.There ______ (be not) a teachers’ building across from the hall. 9.There ______ (be) some chairs under the desk. 10.There ______ (be) a student centre between the gym and library. 11.There ______ (be) a pen and three books on the table. 12.There ______ (be) three books and a pen on the table. 13.Is there ______ (some) water in the cup? 14.There aren’t ______ (some) pictures on the wall. 15.There ______ (be) many desks in front of the whiteboard. 16.There ______ (be) an orange behind the box. 17.______ (be) there a cat under the chair? 18.There ______ (be not) any balls across from the window. 19.There ______ (be) some flowers next to the teachers’ desk. 20.There ______ (be) a map between the two posters. 21.There ______ (be) fifty students in our classroom. 22.There ______ (be) a blackboard in the front of our room. 23.There ______ (be) not any desks behind the library. 24.______ (be) there any trees across from the school gate? 25.There ______ (be) a sofa and two chairs in the corner. 26.There ______ (be) two chairs and a sofa in the corner. 27.There ______ (be) no gym in our small school. 28.There ______ (be) some boxes under the big table. 29.Is there ______ (some) furniture in the student centre? 30.There ______ (be not) any playground behind the classroom. 二、单项选择 考点：就近原则、方位介词辨析、some/any、there be 问答、介词短语辨析 1.There ______ a library and two gyms in our school.
