2.理解-ness名词的属性及常见搭配,能正确变词

4.会用比较级表两者对比、最高级表三者及以上对比
第一部分 后缀-ness - 核心定义
后缀-ness是形容词变抽象名词的名词后缀
加在形容词后,表事物的性质、状态、程度
转化后保留原形容词的核心语义,仅改变词性
核心特点:构成的名词多为抽象概念,贴合原形容词描述属性
例:careful(小心的)→ carefulness(谨慎,表状态)
后缀-ness - 构词规则(一)基本规则
多数形容词可直接加-ness,无需改变原词拼写
规则:形容词原形 + -ness → 抽象名词
直接衔接,字母无增删,拼写简单易掌握
高频例词:
bright(明亮的)→ brightness(亮度)、fit(健康的)→ fitness(健康)
cold(寒冷的)→ coldness(寒冷)、clean(干净的)→ cleanness(干净)
后缀-ness - 构词规则(二)特殊变形
两类特殊情况,需重点记忆,避免拼写错误
1.以y结尾的形容词:变y为i,再加-ness
例:happy→happiness、busy→busyness、lazy→laziness
2.特殊形容词ill:直接加-ness,无需变形
例:ill(生病的)→ illness(疾病)(初中阶段重点掌握)
技巧:特殊变形单独记,结合例词强化记忆
后缀-ness - 名词的核心属性
1.词性:均为不可数名词,无复数形式,不能加s/es
2.修饰词:可被great、deep、strong等形容词修饰
例:great happiness(巨大的幸福)、deep sadness(深深的悲伤)
3.句法功能:可作主语、宾语、表语,符合普通名词用法
例:Happiness is important for everyone.(作主语)
后缀-ness - 常见搭配
搭配结构 核心用法 例句
the + -ness名词 + of 表“……的性质/状态” the brightness of the sun(太阳的亮度)
a sense of + -ness名词 表“……感” a sense of sadness(悲伤感)
动词 + -ness名词 作动词的宾语 show carefulness(表现出谨慎)

第二部分 形容词比较级&最高级 - 核心功能
比较级和最高级用于表示事物的比较程度,用法分两类
1.比较级:用于两者之间的对比,表“一方比另一方更……”
常与than连用,可加much/a little/even加强程度
2.最高级:用于三者及以上的对比,表“最……”
前必须加the,后常接in/of等表范围的短语
形容词比较级&最高级 - 规则变化
变化类型 构成方式 例词(原级→比较级→最高级)
一般单音节词 +er / +est fast → faster → the fastest
以e结尾的单音节词 +r / +st late → later → the latest
辅音字母+y结尾 y变i+er / y变i+est busy → busier → the busiest
重读闭音节(辅+元+辅) 双写末尾辅音+er / +est thin → thinner → the thinnest
多/部分双音节词 more+原级 / the most+原级 interesting → more interesting → the most interesting
形容词比较级&最高级 - 不规则变化
原级 比较级 最高级
good/well better the best
bad/ill worse the worst
many/much more the most
little less the least
far farther/further the farthest/furthest
形容词比较级 - 用法拓展
1.程度修饰:可用much/a little/even/very much修饰,表“……得多/一点”
例:much colder(冷得多)、a little bigger(大一点)
2.省略结构:比较对象相同时,可省略than后的重复部分
例:She is taller than I (am).
3.特殊句式:A+be+比较级+than+any other+单数名词(表“A是范围内最……”)
例:He is taller than any other student in his class.
形容词最高级 - 用法拓展
1.范围提示:后常接in+大范围/of+具体群体,明确比较范围
例:the best student in our class、the tallest of the three boys
2.修饰词:可用the very/the most等修饰,加强语气
例:the very best book(最好的书)
3.省略the:形容词最高级前有物主代词时,省略the
例:It’s my happiest day.(不用the happiest)
形容词比较级&最高级 - 高频易错点
1.规则变化:辅音+y结尾忘变i、重读闭音节未双写辅音
2.最高级:漏加the、忘记接表范围的短语
3.不规则变化:混淆good/well的比较级最高级(错写为gooder)
4.比较级:用more修饰单音节词(错写为more fast)
5.程度词:用very修饰比较级(错写为very taller,正确为much taller)
