形容詞比較級和最高級絕大多數(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。 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 形容詞的比較級和最高級: 形容詞的比較級和最高級形式是在形容詞的原級形式的基礎(chǔ)上變化的。 分為規(guī)則變化和不規(guī)則變化。 規(guī)則變化如下: 1) 單音節(jié)形容詞的比較級和最高級形式是在詞尾加 -er 和 -est 構(gòu)成。 great (原級) (比較級) (最高級) 2) 以 -e 結(jié)尾的單音節(jié)形容詞的比較級和最高級是在詞尾加 -r 和 -st 構(gòu)成。 wide (原級) (比較級) (最高級) 3)少數(shù)以-y, -er, -ow, -ble結(jié)尾的雙音節(jié)形容詞的比較級和最高級是在詞尾加-er 和-est 構(gòu)成。 clever(原級) (比較級) (最高級)4) 以 -y 結(jié)尾,但 -y 前是輔音字母的形容詞的比較級和最高級是把 -y 去掉,加上 -ier 和-est 構(gòu)成. happy (原形) (比較級) (最高級) 5) 以一個輔音字母結(jié)尾其前面的元音字母發(fā)短元音的形容詞的比較級和最高級是雙寫該輔音字母然后再加-er和-est。 big (原級) (比較級) (最高級) 6) 雙音節(jié)和多音節(jié)形容詞的比較級和最高級需用more 和 most 加在形容詞前面來構(gòu)成。 beautiful (原級) (比較級) (比較級) difficult (原級) (最高級) (最高級) 常用的不規(guī)則變化的形容詞的比較級和最高級: 原級-比較級-最高級 good-better-bestmany-more-most much-more-most bad-worse-worst far-farther, further-farthest, furthest old -older,elder-older,eldest 形容詞前如加 less 和 least 則表示較不和最不 important 重要 less important 較不重要 least important 最不重要 形容詞比較級的用法: 形容詞的比較級用于兩個人或事物的比較,其結(jié)構(gòu)形式如下: 主語+謂語(系動詞)+ 形容詞比較級+than+ 對比成分。 也就是, 含有形容詞比較級的主句+than+從句。注意從句常常省去意義上和主句相同的部分, 而只剩下對比的成分。 Our teacher istaller thanwe are. 我們老師的個子比我們的高。 It is warmer today than it was yesterday. 今天的天氣比昨天暖和。 This picture is than that one. 這張照片比那張照片漂亮。This meeting is than that one. 這次會議不如那次會議重要。 The sun is than the moon. 太陽比月亮大得多。形容詞最高級的用法: 形容詞最高級用于兩個以上的人和物進行比較, 其結(jié)構(gòu)形式為: 主語+謂語(系動詞)+the+形容詞最高級+名詞+表示范圍的短語或從句。 She is student her class. 她是班上最好的學(xué)生。 Shanghai is one of cities China. 上海是中國最大城市之一This is apple I have ever met. 這是我見到的最大的蘋果。 Tom is boy in his basketball team. 湯姆是他們籃球隊中個子最高的孩子。 1.
