形容词和副词的概念 形容词:是修饰名词(人或事物),表示名词的性质,特征或属性一种词类。 它在句中作定语、表语和宾语补足语 副词:用来修饰动词、形容词及其他副词的词叫副词。副词在句中多作状语. 形容词和副词的用法 ①形容词作定语一般放在被修饰的名词之前。如: a new book, two big trees 等。 特殊:如果形容词作定语修饰不定代词something, everything, nothing等时,要放在不定代词后面。 如:something interesting nothing new ②形容词放在系动词be 、look、 get、keep、turn、feel、become、seem、 grow、 smell等之后叫表语。如:1.I am short. 2.She looks fine. 3.They turn green. ③如果形容词作宾语补足语的情况I find him handsome. I think it easy to play soccer. We should make our country strong. Please keep our classroom clean. ④副词放在所修饰的动词之后、形容词和副词之前。如果前面是行为动词,则后面用副词。如: 1.She works hard .(修饰动词) 2.I am very busy.(修饰形容词) 3.He runs too quickly .(修饰副词) 4.We play happily. (修饰动词) ⑤通常在形容词后加-ly变成副词。 slow → ______ real → ______ usual →______ careful→______ easy → ______ happy→ ______ heavy →______ angry→ ______ 形容词和副词的级 形容词和副词有三个等级: 原级、比较级、最高级 1.原级:即形容词和副词的原形。 The box is small. They has many books. She is good . We work hard 程度副词very,too,so,quite等修饰形容词和副词的原级。 Yao Ming is very tall. It’s too/so hot today. The story is quite interesting. 2.比较级: 形容词比较级用于两者(人或事物)之间的比较,表示其中一个比另一个“更……”或“较……”,后面用连词than连接另一个所比较的人或事物。例如: (1).That ruler is longer than this one. (2).Mary is younger than me (I). 3.最高级:三个或三个以上的人或物之间 的比较。标志词:in+时间/空间范围, of +与主语同一类的人或物,表示“最……”的意思在形容词的最高级前必须加the; 副词之前可以不加。 Eg:I am the shortest in my family. She has the most books of all the students. He runs fastest in my class. He is the tallest of the 3 boys. 4.比较级和最高级词的构成: 构 成 方 法 原 级 比 较 级 最 高 级 单音节词和少数双音节词 一般在词尾加-er/ə/或-est/ist/ cold colder coldest fast faster fastest 以字母e结尾的形容词,加-r或-st nice nicer nicest large larger largest 重读闭音节词只有一个辅音字母时,应先双写辅音字母;再加-es或-est big bigger biggest hot hotter hottest 以“辅音字母+y”结尾的双音节词,先改“+y”结尾的双音节词,先改“y”为“i”,再加-er或-est easy easier easiest early earlier earliest 多音节词和部分双音节词 在词前加more或most tired more tired most tired easily more easily most easily 不规则变化 good/well→ → many/much → → little → → bad/badly/ill→ → far→ / → / 特殊情况: ①有些双音节和单音节形容词,既可以加er或est构成比较级和最高级,也可以加more 和most构成比较级和最高级。 friendly –friendlier-friendliest/more friendly-most friendly ②某些单音节形容词,加more, most 构成比较级和最高级。 glad – more glad – most glad pleased – more pleased – most pleased tired – more tired – most tired often-more often- most often 写出下列词的比较级和最高级形式 long new cheap young late safe thirsty hard high few old expensive interesting carefully quickly 比较级的具体用法: (1) …than… 汤姆比杰克高.
