形容詞的比較級

1、形容詞的比較級形容詞的比較級1. 含義絕大多數(shù)形容詞有三種形式，原級，比較級和最高級，以表示形容詞說明的性質(zhì) 在程度上的不同。（1） 形容詞的原級：形容詞的原級形式就是詞典中出現(xiàn)的形容詞的原形。例 如:poor，tall ，great， glad， bad。（2）形容詞的比較級：形容詞的比較級表示 更”，用于兩者之間的比較，用來說明前者比后者更”，比較級前面一般用 much, even, a little, a lot修飾，其中even, much只能修飾比較級。2. 形容詞比較級的構(gòu)成：單音節(jié)詞和少數(shù)雙音節(jié)詞類別構(gòu)成方法原級比較級一般直接加-erlongIon gertalltaller不發(fā)

2、音的e結(jié)尾時(shí)加-rlatelaterlargelarger單音節(jié)詞和少 數(shù)雙音節(jié)詞輔音字母加y結(jié)尾時(shí)把y變i，再加-ereasyeasierhappyhappier重讀閉音節(jié)結(jié)尾并且只有 一個(gè)輔音字母時(shí)，雙寫最后bigbigger的輔音字母，再加-erhothotterfat/thi nfatter/th inner多音節(jié)詞和部分雙音節(jié)詞:類別構(gòu)成方法原級比較級多音節(jié)詞和部分雙 音節(jié)詞在原級前加morecareful beautifulmore carefulmore beautiful在原級前加lessimporta nt usefulless importa ntless useful少數(shù)

5、 比較級+ of the twoHe is the betterof the two . 他是這兩個(gè)人中比較好的。(2)關(guān)于形容詞比較級的更多用法比較級前面可以加上表示具體數(shù)量差別的結(jié)構(gòu)，表示具體 大多少”小多少” 長多少”短多少”等。I am two years older tha n he我 比他大兩歲。This building is 20 meters higher than that one這個(gè)建筑物比那個(gè)高 20 米。練習(xí)一.用括號中所給動詞的正確形式填空。1.
