形容詞,副詞:比較級,最高級
(一)形容詞的比較級
1.形容詞比較級在句子中的運用:兩個事物或人的比較用比較級,比較級后面一般帶有單詞than。比較級前面可以用more, a little來修飾表示程度。than后的人稱代詞用主格(口語中可用賓格)。
2.形容詞加er的規(guī)則
?、?一般在詞尾加er ;
?、?以字母e 結(jié)尾,加r ;
?、?以一個元音字母和一個輔音字母結(jié)尾,應雙寫末尾的輔音字母,再加er ;

twenty-first,two hundred and forty-fifth
基數(shù)詞轉(zhuǎn)為序數(shù)詞的口訣:
基變序,有規(guī)律,詞尾加上-th.
一,二,三,特殊記,詞尾字母t,d,d.
八去t,九去e, ve要用f替。
ty將y變成i,th前面有個e.
若是碰到幾十幾,前用基來后用序。
