 ♣ buy sb sth, buy sth for sb
　buy　接双宾语时可采用上面这两种语序，但并非任何情况下都可以互换。当直接宾语是名词时，这两种语序均可使用，但直接宾语是代词时，只能用buy sth for sb. 例如：

 ♣ buy, afford
　参见afford条。
 ♣ buy, purchase
　这两个词的共同意思是“买”。其区别是：buy是普通用词，通常用于买菜、买肉、买房子、买珠宝等；purchase是正式用语，表示经过周密计划以后才买，或是由于业务上的需要大规模地购买，所以在许多用purchase的场合都可以用buy，但许多用buy的场合却不一定能用purchase. 例如：
　You can buy anything in that store for less than ten dollars.　在这家商店里，花上不到10美元你就可以买上任何东西。
　They purchased〔bought〕 a new house.　他们买了一栋新房子。
