1. hard, hardly
hard与hardly这两个副词形式上很接近,但意义上相差甚远。hard可用作形容词或副词。用作形容词时意为“困难的,硬的,勤奋的,严厉的,苛刻的”;用作副词时,意为“努力地,猛烈地,剧烈地”。hardly是副词,意为“简直不能”,多和can连用,接近almost not;也可表示“几乎没有”的意思,常和any连用,接近almost no。

no可用作形容词,也可用作副词。not只可用作副词。no用作形容词,可直接置于名词前面。no后面的名词可用单数形式,也可用复数形式,但有时应依实际情况而定。如果名词前已有a, the, his, much, any等词时,则应该在这些词前面用not。

a lot和a lot of都可以作“许多”解。a lot可以用作名词,在句子中充当宾语,也可以用作副词,修饰动词或用来修饰比较级。a lot作副词用时,也可作“非常,特别”解,用作程度状语,相当于very much。a lot of后接名词,既可接可数名词,又可接不可数名词,多用于肯定句中。在疑问句和否定句中常用many或much代替a lot of。
