英语中in or with后加名词=形容词加ly,

in和with是介词,后面跟名词。in 或with后加名词=形容词加ly,这句话的意思是说：In 或with 后加名词就相当于是一个副词,在句中作状语。例如： I will give him the present in person。可变为 I will give him the present personally。其中in person的意思是“亲自”修饰动词give,修饰动词的词是副词,所以in person就相当于是一个副词。 还有in general就等于generally, He jumped with joy。可变为 He jumped joyfully。 关键理解这句话In 或with 后加名词就相当于是一个副词。
