trade的用法：

1.trade用作名词表示一般性非具体的“买卖，贸易，生意”时，是不可数名词，其前一般不加冠词。

2.trade用作可数名词时，可表示“具体的生意或行业”“谋生手段，手艺，职业”等。作“生意”解时，通常后接介词in引导的短语，表示“…方面的生意”，作“谋生手段，手艺，职业”解时，通常指需要特殊手工的技巧。

3.trade还可作集合名词，在英式英语中是“(从事某行业的)同仁，同行，同业”的总称，在美式英语中是“顾客，主顾”的总称，此时通常要加定冠词the，只有单数形式。当其在句中充当主语时，其谓语动词既可用单数形式，也可用复数形式。

4.trade用作动词的基本意思是从事贸易、做买卖或进行商品交换。引申可指交换位置、交换邮票等。

5.trade既可用作及物动词，也可用作不及物动词。用作及物动词时，接名词或代词作宾语，常与for，in等连用，用作不及物动词时，常与on〔upon〕，with等连用，还与at连用表示“在…买东西”，多用于美式英语中。
