用法归纳
①“否定词+比较级(+than...)”相当于最高级,通常意为“　 　 　　　　　　 ” “……是
最……的”或“完全,十分,非常”。用“否定词+比较级”表示最高级的意义比直接用最高
级更有说服力。

a.一些否定词,如nobody、　　　 等作主语,或“no+名词”“no other+名词”作主语与比
较级连用。
b.can't/cannot/couldn't或never、not、no等否定词与比较级连用。

用法归纳
　　①too...to do sth.结构在多数情况下表示否定意义,意为“太……而不能做某事”。该结
构中,too为副词,后接形容词或副词,不定式作　　　 状语。
结果
②在too...to do sth.结构中,若too后是表示某种心情或倾向的形容词,如anxious、glad、
pleased、delighted、willing、eager等,该结构往往不表示否定意义,而表示肯定,此时too前通
常有only、simply、just等词修饰,too和前面的only、simply、just等词一起相当于very。
③“　　　 /can never be+too+adj.+to do sth.”表示做某事时再……也不过分,做某事时越
……越好。

化,还可以与某些情态动词连用(通常不与can连用),甚至还可以有非谓语动词形式。
易混辨析(can/be able to)
can和be able to都可以表示能力,前者表示主语原本就具有某种能力,后者表示通过努力可以
