人教版八年级上册 Unit 3 Same or Different？ 语法专项精讲精练 一、语法精讲：形容词/副词比较级（融合“校园双减与体育美育”热点） 1. 核心逻辑：用比较级描述“双减”下的校园变化 本单元的形容词/副词比较级，本质是用“对比”的语言，描述人/事物的差异。我们可以结合双减政策下校园体育、美育活动的变化来理解和运用： 对比过去与现在的校园设施： The new playground is bigger than the old one.  （新操场比旧操场大） 对比不同同学的特长： Li Ming runs faster than Wang Tao in PE class.  （体育课上李明比王涛跑得快） 对比不同活动的吸引力： The after-school art club is more popular than the chess club.  （课后美术俱乐部比象棋俱乐部更受欢迎） 2. 比较级的构成（结合校园场景记忆） 类型 变化规则 校园相关例子 单音节词 直接加 -er    fast → faster （跑步更快）、 tall → taller （个子更高） 以 e 结尾 加 -r    nice → nicer （更好）、 late → later （更晚） 重读闭音节 双写尾字母加 -er    big → bigger （操场更大）、 thin → thinner （体重更轻） 辅音+y结尾 变 y 为 i 加 -er    happy → happier （学生更开心） 多音节词 加 more  interesting → more interesting （活动更有趣） 不规则变化 特殊记忆   good/well → better （表现更好）、 many → more  （活动更多）、 little → less （作业更少） 3. 核心句型（结合热点场景） 两者对比： A + 比较级 + than + B  例：  Students have more free time than before under the "double reduction" policy.  （双减政策下，学生比以前有更多空闲时间） 同级比较： as + 原级 + as  例：  The art class is as popular as the PE class in our school.  （我们学校的美术课和体育课一样受欢迎） 否定同级比较： not as/so + 原级 + as  例：  The homework now is not as heavy as it was two years ago.  （现在的作业不像两年前那么多了） 二、精练试题（融合双减校园热点） （一）用所给词的适当形式填空 1. Under the "double reduction" policy, students have ______ (much) time to take part in after-school activities than before. 2. The new school sports meeting is ______ (exciting) than the last one, with more events for students to join. 3. Li Hua runs ______ (fast) than most of his classmates, so he will represent our school in the city sports meet. 4. The after-school reading club is ______ (popular) than the basketball club in Grade 8. 5. The new school library is ______ (big) than the old one, and it has ______ (many) books about sports and art. （二）单项选择 1. The PE classes now are ______ interesting than before, and students are ______ active in them.
