比较等级和比较结构
英语中大多数形容词和副词都是“可等级的”（Gradable），因而可以用于比较结构。当形容词和副词用于比较结构时，它们采取特殊的语法形式，这就是比较结构。
25．1 形容词和副词的比较等级亲情作文结尾
大多数形容词和副词的比较等级有三：原级（Positive/Absolute Degree）、比较级（Comparative Degree）和最高级（Superlative Degree）。比较级和最高级又可分为、规则形式和不规则形式。大多数形容词和副词的比较级和最高级都是规则的，只有少数几个是不规则的。兹分述如下。
1） 形容词比较级和最高级的规则形式
形容词比较级和最高级的规则形式有两种表示方法：一是由原级加后缀-er和-est构成，即所谓“综合形式”（Synthetic Form）；二是在原级之前加more和most构成，即所谓“分析形式”（Analytic Form）。
一般说来，单音节形容词的比较级和最高级多采用综合形式，即加-er和-est的形式。例如：
Kind kinder kindest
Clear clearer clearest
Old older oldest
Cold colder coldest
Long longer longest
三音节或多于三音节的形容词，其比较级和最高级通常采用分析形式，即在原级之前加more和most的形式。例如：
Instructive more instructive most instructive
Beautiful more beautiful most beautiful
张英俊Difficult more difficult most difficult
Complicated more complicated most complicated
Contemptible more contemptible most contemptible
双音节形容词的比较级和最高级通常既可采用综合形式，也可采用分析形式。例如：
Tender tenderer/more tender tenderest/most tender
Clever cleverer/more clever cleverest/most clever
双音节形容词的比较级和最高级通常既可采用两种形式，但以-y结尾和以水土保持与荒漠化防治-ow结尾的双音节形容词多半采取综合形式。例如：
Happy happier happiest
Pretty prettier prettiest
Narrow narrower narrowest
Shallow shallower shallowest
2） 副词比较级和最高级的规则形式
副词比较级和最高级规则形式的构成与形容词比较级和最高级基本相似。单音节副词通常采用综合形式。例如：
Fast faster fastest
Hard harder hardest
Soon sooner soonest生活因友谊而精彩
Late later latest
而以-ly结尾的副词以及某些频度副词则多半采用分析形式。例如：
Clearly more clearly most clearly
Wily more wily most wily
Frugally more frugally most frugally
Often more often most often
3） 形容词、副词比较级和最高级的不规则形式
有少数几个形容词和副词的比较级和最高级是不规则的，它们是：
Bad wor worst
Good/well better best
Old older/elder oldest/eldest
Far further/farther furthest/farthest
Much more most
Badly wor worst
Well better best
