形容詞和副詞比較級的變化規(guī)則
形容詞和副詞比較級的規(guī)則變化
分類 變化方式 示例
一般情況 直接在詞尾加 er tall—taller short—shorter
以不發(fā)音的字母e結(jié)尾 的詞 只在詞尾加 r nice—nicer late—later
重讀閉音節(jié)詞詞尾只有一個輔音字母 先雙寫該輔音字母，再加er thin—thinner
big—bigger
以“輔音字母+y”結(jié)尾的雙音節(jié)詞 先變y為i，再加er heavy—heavier
easy—easier
多音節(jié)詞和部分雙音 節(jié)詞 在詞前加more outgoing—more outgoing beautiful—more beautiful
比較級要變化，一般詞尾加 er。
詞尾若有啞音e，直接加r就可以。
輔音字母若加y, 記得變y為i。
一輔重讀閉音節(jié)，末尾字母要雙寫。
多、雙音節(jié)有規(guī)律，詞前加more就可以。
比較級規(guī)則變化助記口訣
good/well → better
bad/badly → worse
many/much → more
little → less
far → farther/further
