译林版四年级上册Unit 5 Different toys, same fun
常考易错语法专项练习
语法一:have/has 主谓一致用法【核心必考、失分重灾区】
1. 核心含义:have/has 均表示“拥有”,是单元核心谓语动词,唯一区别由主语人称和单复数决定。
2. 固定用法规则:第一人称(I/We)、第二人称(you)、复数主语(they/students/toys等)后统一用have;第三人称单数(he/she/it/单个人名/单数物品)后统一用has。
3. 基础句型结构:肯定句:主语+have/has+物品/特征;否定句:主语+don’t/doesn’t+have+物品(三单主语用doesn’t,其余用don’t);一般疑问句:Do/Does+主语+have+物品?
4. 例句示范:I have a nice toy plane.(我有一架好看的玩具飞机);She has two big eyes.(她有一双大眼睛);They have many different toys.(他们有许多不同的玩具)。
1. 主谓搭配错误:高频失分!单数主语误用have,复数主语误用has,错例:He have a toy car.(正确:He has...)。
2. 否定句拼写错误:三单主语否定误用don’t,或否定句中have变has,错例:She doesn’t has a doll.(正确:doesn’t have)。
3. 疑问句规则混淆:助动词Does开头的问句,后面动词未还原成have,是期末判断题、改错题高频考点。

语法二:a lot of / a lot 用法辨析【易混难点、填空常考】
1.a lot of = lots of,意为“许多、大量”,后面必须接名词,可修饰可数名词复数或不可数名词,多用于句中修饰事物。
2.a lot 意为“非常、很多”,后面不接任何名词,多用于句末,修饰动词、形容词,表程度。
3.核心例句:We have a lot of toys.(我们有许多玩具,修饰名词toys);I like my toy bear a lot.(我非常喜欢我的玩具熊,修饰动

词like)。
4.拓展:fun为不可数名词,可用a lot of fun表示“很多乐趣”,无复数形式,不可说many funs。
1.搭配混用错误:a lot 后误加名词,错例:I have a lot toys.(正确:a lot of toys)。
2.句式位置混淆:句末表程度误用a lot of,错例:I like it a lot of.(正确:a lot)。
3.名词单复数误区:a lot of 修饰可数名词时,名词必须用复数,遗漏s为常见拼写错误。
