副词的比较级，副词的最高级形容词副词不定式现在完成时

考点名称：副词的比较级，副词的最高级

• 副词的比较级和最高级：
  当两种物体之间相互比较时，我们要用形容词或副词的比较级；
  当相互比较的物体是三个或三个以上时，我们就要用形容词或副词的最高级。
  副词比较级和最高级的变化规则和形容词相似。

• 副词比较级的变化规则：
  

  一、规则变化<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />

  1.一般在词尾直接加er或est。hard—harder—hardest ；long-longer-longest

  2.以不发音的字母e结尾的单词在词尾直接加r或st。nice-nicer-nicest

  3.以辅音字母+y结尾的词，把y变为i，再加er或est。early—earlier—earliest 
  4.重读闭音节，末尾只有一个辅音字母，双写这个辅音字母，再加er或est，例如，big-bigger-biggest

  5.部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级， carefully—more carefully—most carefully
  
  二、不规则副词的比较级和最高级
  

  原级	比较级	最高级
  well	better	best
  badly	worse	worst
  much	more	most
  little	less	lest
  far	farther(指距离)	farthest(指距离)
  	further(指距离和抽象概念)	furthest(指距离和抽象概念)

• 以ly结尾的副词，比较级有两种情况：
  一种单词里本身就以结尾early；
  另一种是由形容词+变为的副词 slowly，happily ，easily，他们改为比较级时 是不一样的。
  例如：第一种情况，直接进行词尾变化early-earlier；
  而第二种情况， 就要在副词原级前面+more，构成比较级。
  因此，easily 的比较级应该是：more easily 。

• 副词等级的用法：
  一、原级的用法
  1.只能修饰原级的词，very，quite，so，too。例如：
  He is too tired to walk on.他太累了以至于不能再继续走了。
  My brother runs so fast that I can‘t follow him.我弟弟跑得那么快以至于我跟不上他。
  2.原级常用的句型结构
  (1)“甲+实意动词+(倍数)+as+副词原级+as+乙”表示“甲和乙程度相同”或“甲是乙的几倍”。例如：
  Tom runs as fast as Mike.汤姆和迈克跑得一样快。
  Tom runs twice as fast as Mike.汤姆跑得速度是迈克的二倍。
  (2)“甲+助动词+not+动词原形+as/so+副词原级+as+乙”甲不如乙…例如：
  He doesn’t walk as slowly as you.他走路不像你那样慢。
  
  二、比较级的用法
  1.可以修饰比较级的词，much，a lot，far，…的多； a little，a bit，…一点儿； even甚至;；still仍然。例如：
  Lesson One is much easier than Lesson Two.第一课比第二课容易得多。
  Tom looks even younger than before.汤姆甚至比以前更年轻。
  This train runs much faster than that one.这辆火车比那辆跑地快。
  She drives still more carefully than her husband.她开车仍然比她丈夫还认真。
  
  2.比较级常用的句型结构
  (1)“甲+实意动词+(倍数)+副词比较级+than+乙”表示“甲比乙…”或“甲比乙…几倍”。例如：
  I got up earlier than my mother this morning.我今天早晨起床比我妈妈还早。
  He runs three times faster than his brother.他跑的速度比他弟弟快三倍。
  (2)“甲+实意动词+副词比较级+than+anyother+单数名词(+介词短语)”表示“甲比同一范围的任何一个人/物都……”，含义是“甲最……”。例如：
  Mike gets to school earlier than any other student in his class.
  = Mike gets to school earlier than any of the other students in his class.迈克比他们班上任何一个其他的同学到校都早。
  = Mike gets to school earlier than the other students in his class.迈克比他们班上其他的同学到校都早。
  = Mike gets to school earliest in his class.迈克在他们班到校最早。
