译林英语八上Unit3语法讲解及习题: 副词比较级与最高级、反身代词、职业后缀构词法 第一部分 核心语法一:副词比较级与最高级 一、语法总述 副词比较级、最高级用于比较动作发生的方式、速度、程度。比较级用于两者动作对比,意为“更……地”;最高级用于三者及以上动作对比,意为“最……地”。副词最高级前的定冠词the可省略,这是区别于形容词最高级的核心考点,广泛用于单选、句型转换、词形填空题型。 2、 变形规则 1. 规则变化 (1)单音节副词:直接在词尾加-er(比较级)、-est(最高级) 例:fast(快速地) faster fastest;hard(努力地) harder hardest;high(高地) higher highest;early(早地) earlier earliest (2)多音节及部分双音节副词:词前加more(比较级)、most(最高级),单词本身不变形 例:carefully(认真地) more carefully most carefully;quickly(快速地) more quickly most quickly;actively(积极地) more actively most actively 2. 不规则变化(必考必背) well(好地) better best;badly(糟糕地) worse worst;far(远地) farther/further farthest/furthest 三、核心句型与用法 1. 副词比较级句型(两者对比) 结构:主语 + 动词 + 副词比较级 + than + 对比对象 例句:He studies harder than his deskmate.(他比同桌学习更努力。) 2. 副词最高级句型(三者及以上对比) 结构:主语 + 动词 + (the) 副词最高级 + 范围(in/of...) 关键考点:副词最高级前the可加可省略,无硬性要求,是高频易错点 例句:She sings (the) best in our class.(她是我们班唱歌最好的。) 3. 拓展用法 可套用比较级固定句型:比较级+and+比较级(越来越……)、The+比较级,the+比较级(越……越……) 例句:He runs faster and faster.(他跑得越来越快。) 第二部分 核心语法二:反身代词 一、语法总述 反身代词意为“某人自己”,核心使用场景:句子主语和动作承受者为同一人/物。反身代词不能单独作主语,只能作宾语、表语或同位语,常搭配固定短语考查。 二、反身代词表格 人称 单数 复数 第一人称 myself(我自己) ourselves(我们自己) 第二人称 yourself(你自己) yourselves(你们自己) 第三人称 himself/herself/itself(他/她/它自己) themselves(他们/她们/它们自己) 3、 固定短语 1. by oneself 独自、单独 = alone 例句:I can finish the work by myself.(我可以独自完成这项工作。) 2. enjoy oneself 玩得开心 = have a good time 例句:They enjoyed themselves at the party.(他们在派对上玩得很开心。) 3. teach oneself 自学 例句:She teaches herself English every day.(她每天自学英语。) 4. hurt oneself 伤到自己;look after oneself 照顾自己 第三部分 核心语法三:职业后缀构词法(-er/-or/-ist) 一、语法总述 本组后缀为名词构词考点,通过在动词、名词后添加固定后缀,转化为对应职业、身份的人,三类后缀分工明确,含特殊变形规则,主要考查词形转换、词义辨析。 二、三大后缀精讲 1. 后缀 -er(最常用) 多用于普通动作动词后,表“执行者、从业者”;以不发音e结尾的动词,直接加-r。 例:work worker(工人)、visit visitor(游客)、write writer(作家)、dance dancer(舞者)、print printer(印刷工)、win winner(获胜者) 2. 后缀 -or 多用于部分特殊动词,多为科技、管理类职业,无规律,重点记忆高频词。 例:invent inventor(发明家)、manage manager(经理)、act actor(演员) 3. 后缀 -ist 多用于学科、艺术、专项领域名词后,表“专家、从业者、爱好者”。 例:science scientist(科学家)、piano pianist(钢琴家)、tour tourist(游客)、biology biologist(生物学家) 三、易错点总结 1. 区分动词原形与职业名词,做题禁止混用(invent动词,inventor职业名词); 2. 去e变形为高频考点:write/dance直接加r,不可重复加e; 3. -ist多对应专业领域人才,是词义辨析核心区分点。 第四部分 综合专项练习题 题型一:单项选择 1.
