cost的用法：
cost的用法1：cost的基本意思是“对得到的事物、行为或事情的结果付出代价”,可依据上下文灵活译为“值…”“花费”或“失去”“蒙受”“招致”等。引申还可表示“估算成本”“计算费用”。cost侧重的是“以…为代价”,而不仅仅是数量的陈述。
cost的用法2：cost主要用作及物动词。作“花费”“付出代价”解时,不用于被动结构,主语通常是物或事物。接名词或代词作宾语时,宾语为金钱、时间、精力等(在当代英语中,这一范围正不断扩大)。接双宾语时,直接宾语为金钱、时间、精力等,间接宾语则总是人。作“计算费用”“估算”解时主语一定是人,且可用于被动结构。
cost的用法3：cost也可用作不及物动词,意为“需要花费”“需要付出代价”,这时其后一般有副词性状语。
cost的用法4：cost也可用作系动词,可接形容词,表被动意义。
cost的用法5：cost的过去式和过去分词有两种形式,作“花费”“失去”解时用cost,作“估算”解时则是costed。
