常见误用提醒
使用 expended：I expended my money to buy a book. → I spent my money on a book. (在口语或非正式语境中，'spent' 更常用；'expended' 通常用于更正式或强调资源耗尽的场合，搭配 'on' 而非 'to'。)
使用 expended：He expended all his time for studying. → He expended all his time on studying. ('expended' 后应接 'on' 表示花费在某个活动上，而不是 'for'，这是介词搭配错误。)
使用 consumed：He is consumed about his job. → He is consumed by his job. (“consumed”后通常接“with”或“by”，而不是“about”。“about”用于表示关于某事的普通兴趣，而“consumed”强调完全占据的状态。)
