expend

expend 是及物动词，表示为了某个目的消耗、用尽资源，常用于时间、精力、金钱等较正式的语境。

💡 记忆钩子

把资源想成一笔存量：一旦为了某个目标主动拿出来使用，就是 expend；重点不只是“用”，而是把一部分资源花掉、耗掉。

📝 学习建议

先把 expend 记作较正式的“消耗、花费”，不要只按普通的“花钱”理解。
它和 spend 意思接近，但 expend 在日常会话中不如 spend 常见，学习时可先掌握 spend，再把 expend 作为正式替换词记忆。

📖 中文释义

verb

core 消耗；用尽资源

📖 为了完成某件事而主动消耗某种资源，如时间、精力、金钱或其他有限的东西；语气常带有“把存量用掉”的感觉。

💡 常见搭配是“expend time/energy/resources on something”或“expend effort in doing something”。它是及物动词，后面通常直接接被消耗的资源；与 spend 意思相近，但 expend 更正式，不能自然地用于所有日常“花钱”场景。

transitive

The team expended a great deal of effort on the project.

团队在这个项目上投入了大量精力。

We should not expend all our resources at once.

我们不应该一下子耗尽所有资源。
