语法速记口诀
近处This远处That,搭配is永不差;
This is不缩写,That is可简写;
my加名词表我的,一般疑问it来答。
一、核心语法精讲
语法点1:近指/远指介绍核心句型(单元必考)
1. This is… (近距离介绍)
用法:介绍近处的人或事物,本单元用于介绍身边的家庭成员
例句:This is my father. 这是我的爸爸。
2. That is… (远距离介绍)
用法:介绍远处的人或事物
例句:That is my mother. 那是我的妈妈。
缩写形式:This is(无缩写);That is = That’s
语法点2:形容词性物主代词 my
用法:my + 名词,表示“我的……”
单元固定搭配:my family(我的家庭)、my father(我的爸爸)、my mother(我的妈妈)、my sister(我的妹妹/姐姐)
核心规则:my 后面必须接家庭成员名词,不能单独使用
语法点3:be动词is单数用法
本单元专属搭配:This / That 作主语,be动词统一用is
句型结构:This/That + is + my + 家庭成员名词
语法点4:一般疑问句及简答(拓展必考)
问句:Is this/that your + 家庭成员? 这/那是你的……吗?
肯定回答:Yes, it is. 是的。
否定回答:No, it isn’t. 不是。
高频易错点
❌ This is 不能缩写,That is 可缩写为 That’s
❌ 问句用 your(你的),答句不用 my,固定用 it 作答
❌ 主语This/That,be动词只能用is,不能用are/am
❌ my 后漏加名词,单独使用my(错误用法)
