七年级英语上册Unit 3 Welcome to our school! 语法专项分层精讲精练 第一部分 单元核心语法精讲 语法一:人称代词(主格和宾格单元重点)★★★ 人称代词是代替人或事物的词,本单元只考查主格、宾格,区分用法是考试核心易错点。 一、核心概念与用法规则 1. 人称代词主格 主格在句中作主语,永远放在句子开头、实义动词/be动词之前,发出动作。 常用主格:I, you, he, she, it, we, they 课本原文例句:We love our school. 我们热爱我们的学校。(we作主语) 课本原文例句:She shows me around the classroom. 她带我参观教室。(she作主语) 2. 人称代词宾格 宾格在句中作宾语,永远放在动词后、介词后,承受动作,不能放句首。 常用宾格:me, you, him, her, it, us, them 课本原文例句:Let me show you around. 让我带你参观。(me、you放在动词后作宾语) 二、必背对应变形(必考变形) 第一人称:I(主)—me(宾) we(主)—us(宾) 第二人称:you(主)—you(宾)(单复数同形,不变形) 第三人称:he(主)—him(宾) she(主)—her(宾) it(主)—it(宾) they(主)—them(宾) 三、三大必考易错点(考试高频丢分点) 1. 句首必须用主格,动词、介词后面必须用宾格,是固定规则,无特殊例外。 2. he/him、she/her 极易混淆:指代男生用he/him,指代女生用she/her。 3. you主宾同形,很多学生盲目变形,属于典型易错陷阱。 四、场景句式精讲(贴合单元校园场景) 1. 主格造句:They are my classmates. 他们是我的同学。 2. 宾格造句:Our teachers help us every day. 我们的老师每天帮助我们。 3. 介词后宾格:Please look at me. 请看我。(介词at后用宾格) 语法二:There be 句型【单元核心句型】★★★ 本单元专门用于描述某地有某人/某物,是校园场景描写专用句型,区别于have(某人拥有某物)。 一、核心句式结构 1. 肯定句 There is + 单数可数名词/不可数名词 + 地点状语 There are + 复数可数名词 + 地点状语 教材场景例句:There is a big library in our school. 我们学校有一个大图书馆。 教材场景例句:There are many classrooms in the building. 这栋楼里有很多教室。 2. 否定句 There isn’t + 单数/不可数名词 There aren’t + 复数名词 例句:There isn’t any water in the bottle. 瓶子里没有水。 例句:There aren’t any books on the desk. 桌子上没有书。 3. 一般疑问句 Is there + 单数/不可数名词? 回答:Yes, there is. / No, there isn’t. Are there + 复数名词? 回答:Yes, there are. / No, there aren’t. 二、核心解题黄金原则(就近原则) be动词的单复数只看紧跟其后的第一个名词,和后面其他名词无关。 1. 就近单数/不可数 → 用is 例句:There is a pen and two books on the desk.(紧跟a pen单数,用is) 2. 就近复数 → 用are 例句:There are two books and a pen on the desk.(紧跟two books复数,用are) 三、There be 和 have 的终极区分(必考辨析) 1. There be:某地存在有,无主语人称,只表位置存在。 2. have/has:某人拥有有,主语必须是人/物,表所属关系。 正确:We have a nice school. 我们拥有一所漂亮的学校。(人拥有) 正确:There is a nice playground in our school. 学校里有一个漂亮的操场。(地点存在) 绝对禁忌:there be 和 have 绝对不能同时出现在一个句子里。 四、高频固定搭配 本单元专用地点状语:in our school, in the classroom, on the wall, in the hall 第二部分 语法专项精练(原创分层习题) 基础过关练(夯实课本基础) 一、用括号内代词的适当形式填空(主格宾格专项) 1. ______ (I) am a student of this school. 2. Let ______ (we) help ______ (you) with your English. 3. ______ (she) is our new teacher.
