形容詞和副詞的特殊表達法一、形容詞與副詞的同級比較： 由"as(so)…as"引出，其否定式為"not so…"或"not as…as",此外還應注意下列含有"as"結構或短語的句子

六、比較中的省略
1. 在as…as中，as從句可省略整個謂語部分，保留主語

2. 可以省去謂語部分，保留主語和be、have等助動詞

3. 可以省去主語和謂語，只剩下狀語

5. than從句省去部分謂語，保留主語和be,have或助動詞

這時 我們可以進行倒裝，即將than后從句中的be,have或助動詞移到該從句的前邊

相對來說，大變動比小變動畢竟容易些。

10. 為了避免重復，我們經常用that代替不可數名詞, those代替復數名詞,one代替可數名詞單數
七、隱含比較級
有時比較級并不一定出現than，這時通過上下文可喑示出，如：-Of the two oranges, which do you choose? -I like the larger one.這里的larger one是指前邊提到的兩個當中的較大的一個。而且有些形容詞在表示比較的時候，跟"to"而不用"than"
1. prior to 較早的，較重要的
