初中形容詞比較級(jí)和最高級(jí)及練習(xí)

1、形容詞、副詞的比較級(jí)和最高級(jí)的用法：1.大多數(shù)的形容詞都有三個(gè)級(jí)別：原級(jí)、比較級(jí)、最高級(jí)。一、形容詞、副詞的比較級(jí)和最高級(jí)的變化規(guī)律：1. 單音節(jié)形容詞或副詞后面直接加-erer或-esti:st talltallertallest fastfasterfastest2. 以-e結(jié)尾的單音節(jié)形容詞或副詞直接加-r或-st largelargerlargest nicenicernicest3. 以-y結(jié)尾的形容詞或副詞，改-y為-i再加-er或-est busybusierbusiest earlyearlierearliest4. 形容詞或副詞是重讀閉音節(jié)時(shí)，雙寫(xiě)最后的輔音字母，再加-er或

2、-est hothotterhottest bigbiggerbiggest5. 多音節(jié)形容詞或副詞前面直接加more或most deliciousmore deliciousmost delicious beautifulmore beautifulmost beautiful6. 不規(guī)則變化 good (well)betterbest bad (badly)worseworst注意：形容詞的最高級(jí)前通常要加冠詞the，副詞前可加可不加。 二、比較級(jí)的定義： 當(dāng)兩種事物（人或物體）之間相互比較時(shí)，我們要用形容詞或副詞的比較級(jí)，比較級(jí)表示“更”，用于兩者之間的比較，用來(lái)說(shuō)明“前者比后者更”，比

3、較級(jí)前面一般用much, even, a little修飾，表示程度；其中even, much 只能修飾比較級(jí)。形容詞、副詞的比較級(jí)和最高級(jí)的句子構(gòu)成：1.比較級(jí)：表達(dá)“A大于B” 物體A + am / are / is + 形容詞比較級(jí) + than + 物體B. I am taller than you. Pasta is more delicious than pizza. 物體A + 行為動(dòng)詞 + 副詞比較級(jí) + than + 物體B. Mary runs faster than Sam . He studies better than me.表達(dá)“A和B一樣”，用asas的結(jié)構(gòu)。 A

5、armer天氣越來(lái)越暖和。He is running faster and faster他跑得越來(lái)越快。0ur country is becoming more and more beautiful我們祖國(guó)越來(lái)越美了。2.表示“越，就越”，“the more， the more”，The more，the better.多多益善。The more careful you are,the fewer mistakes you will make.你越細(xì)心，犯錯(cuò)就越少。三、最高級(jí)的定義：當(dāng)三個(gè)或三個(gè)以上的人或事物進(jìn)行比較時(shí)，我們需要用到形容詞（副詞）的最高級(jí)1）物體A + am / are / i
