  (一)形容词、副词的比较级和最高级
  英语中当要表示“比较......”以及“最......”的时候,往往要用比较级和最高级。形容词和副词都有比较级和最高级,其构成方法有两种:一种是直接在形容词或副词后加词缀-er,-est;另一种是在形容词和副词前面加副词more,most。
  1.加-er,-est(适合于单音节词和一部分双音节词),如:
  原型     比较级    最高级
  early     earlier    earliest
  quick     quicker    quickest
  small     smaller    smallest
  2.加副词more,most(适合多音节词和一部分双音节词),如:
  原型      比较级     最高级
  beautiful more beautiful most beautiful
  complicated more complicated most complicated
  valuable more valuable most valuable
  3.少数形容词和副词在变比较级和最高级时有特殊的形式,如:
  原型     比较级     最高级
  good/well better best
  many/much more most
  little less least
  在使用比较级的时候,常常用than引导状语从句,指出谁与谁相比。如:
  He is taller than I.
  She went to school earlier today than (she did ) yesterday.
  I did morning exercises more often this year than(I did ) last year.
