1、形容詞表示某一事物或人的特征，副詞表示某一動作的特征。

　　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

　　兩個重要特征：asas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(guī)則變化如下：

　　(1)一般直接+er。如：tall - taller, fast - faster 單音節(jié)詞如果以-e結(jié)尾，只加-r。如：late - later

　　(2)重讀閉音節(jié)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(jié)尾的詞，變y為i，再加-er。如：heavy - heavier, early - earlier

　　(4)雙音節(jié)和多音節(jié)詞的比較級應在原級前加more構(gòu)成。如：beautiful - more beautiful, careful - more careful, quietly - more quietly, interesting - more interesting

　　(5)有些不規(guī)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

　　2、用括號內(nèi)所給單詞的適當形式填空。

　　1) I can swim as _______ (fast) as the fish, I think.

　　2) Look! His hands are _______ (big) than mine.

　　3) I think you do these things_______ (well) than your classmates.

　　4) Whose bag is _______ (heavy), yours or mine?

　　5) Does Jim run as _______(slow) as David? Yes, but Mike runs_______ (slow) than them.

　　6) You have seven books, but I have _______ (many) than you. I have ten.
