在英语学习中,很多同学对动词 spend 的搭配感到困惑:它后面到底应该接 on 还是 in?本文将为你清晰梳理规则,并通过例句帮助你掌握正确用法。
1. spend + 时间/金钱 + on + 名词
这是最常见且标准的结构,用于表示“在某事上花费时间或金钱”:
- I spent $50 on books.
- She spends two hours on homework every day.
2. spend + 时间 + (in) + 动名词(-ing)
当后面接动词时,通常使用 spend time doing something。此时 in 可省略,现代英语中几乎总是省略:
- He spent the whole afternoon (in) reading. → He spent the whole afternoon reading.
- We spent hours (in) discussing the plan. → We spent hours discussing the plan.
注意:这里不能用 on + 动名词(如 ❌ "spend on reading" 是错误的)。
3. 常见错误提醒
- ❌ I spent money in books. (错误!应为 on)
- ❌ She spent time on watching TV. (错误!应为 watching TV,不加 on)
总结
✅ spend ... on + 名词
✅ spend ... (in) + 动名词(通常省略 in)
记住这个口诀:“on 接物,doing 接动作”,就能轻松掌握 spend 的正确用法!
