用法筆記

More formal than 'spend' or 'use up'. The object must name a resource — typically time, effort, energy, or money — not a physical item. Frequently followed by 'on' plus a noun phrase or by an '-ing' verb form showing the activity the resource was put towards. Common in academic, business, and official contexts.

常見錯誤

✅He lifted the heavy box onto the shelf.
💡'expend' only applies to abstract resources like time, effort, or money, not to physical objects.
❌The company expended a lot on advertising last year.
✅The company expended a lot of money on advertising last year.
💡'expend' is transitive and requires an object naming the resource; do not use it without stating what was spent.
