一般情况下，形容词和副词的最高级的规则变化是在词尾加-est或在其前加most构成，不规则变化则要牢记。形容词和副词的最高级(重读闭音节词词尾只有一个辅音字母时,先双写辅音字母再加-est)(以不发音的字母e结尾的加-st)(词尾加-est)原形最高级规则变化quickquickestfreshfreshestcloseclosestbigbiggest规则(多音节词和部分双音节词前加most)comfortablemostcomfortable(以辅音字母+y结尾的双音节词，变y为i加-est)earlyearliest原形最高级规则cheaply(the)mostcheaplycarefully(the)mostcarefullygood/well—bestill/bad/badly—worstmany/much—most(不规则变化需专门记忆)little—leastfar—farthest/furthest不规则变化old-oldest/eldest2.用法1)形容词的最高级前一般要加定冠词the,但如果其前有形容词性物主代词或名词所有格等修饰语时,则不用定冠词the。

副词的最高级前面可以加定冠词the,也可以省略。

e.g.Thisbookisthemostinterestingone.

Heryoungestdaughteriselevenyearsold.LiuJunran(the)fastestintherace.2)形容词和副词的最高级常与介词in或of短语连用,说明比较的范围。

一般情况下,如果主语与介词短语中的名词属于同一类,用介词of;如果不是同一类,则用介词in。e.g.Tinaisthemostoutgoinginherfamily.Jimjumps(the)highest

ofalltheboys.【温馨提示】有时最高级和比较级可以转换。如：Thiscarruns(the)fastestofallthecars.=Thiscarrunsfasterthantheothercars.=Thiscarrunsfasterthananyothercar.theleast也可表示最高级，表示否定意义。如：Itisoneoftheleastimportantmeetings.
