英語語法：形容詞、副詞
1、形容詞表示某一事物或人的特徵，副詞表示某一動作的特徵。形容詞和副詞有三種形式：原形、比較 級、最高級。比較級：+er 最高級：the …+est
兩個重要特徵：as……as中間一定用原形，than的前面一定要+er。
2、形容詞、副詞比較級的規則變化如下：
（1）一般直接+er。如：tall - taller, fast - faster 單音節詞如果以-e結尾，只加-r。如：late - later （2）重讀閉音節詞如末尾只有一個輔音字母，須雙寫這個字母，再加-er。如：big - bigger, fat - fatter （3）以輔音字母加-y結尾的詞，變y為i，再加-er。如：heavy - heavier, early - earlier （4）雙音節和多音節詞的比較級應在原級前加more構成。如：beautiful - more beautiful, careful - more careful, quietly - more quietly, interesting - more interesting
（5）有些不規則變化的，須逐一加以記憶。如：good/well – better, bad/ill – worse, many/much – more, far – farther/further, old – older/elder…
練一練：
1、寫出下列形容詞、副詞的比較級。
big good long tall old
short thin heavy young fat
light strong high far low
early late well fast slow
