An adjective modifies a noun or a pronoun．Adjectives answer such questions as these:Which?What kind of?How many?Whose?The use of adjectives helps to make both written and oral communications more interesting and more meaningful to readers and listeners．While they appear in all types of business communications，adjectives are especially important in those that have a sale or sales-promotion purpose．

形容词在句中通常修饰名词或代词。在口语中和书面语中恰当地使用形容词可使得交际活动更为生动形象并饶有趣味。形容词在各类商务英语信函中的使用都相当普遍，在商品促销一类的信函中则显得尤其重要。

Adjectives can be classified as descriptive adjectives which describe a quality or a characteristic of someone or something，demonstrative adjectives telling which，limiting adjectives telling how many，proper adjectives，compound adjectives and articles．

形容词按其功能分为描述性形容词、指示性形容词和限定性形容词。另外一些专有的词汇、一些复合形容词和冠词也能在句中起修饰作用。
