不可数名词也能加数字?以 percent 为例
✅ 正确理解
percent
虽然是不可数名词,但可以加数字,读作:
- 10 percent
- 75 percent
- 100 percent
❌ 错误形式
类似结构
名词 |
是否可数 |
举例 |
percent |
❌ |
20 percent of the class |
advice |
❌ |
some advice |
tip |
✅ |
a tip / some tips |
money |
❌ |
a lot of money |
dollar |
✅ |
ten dollars |
equipment |
❌ |
some equipment |
🧠 小结
不可数名词通常不能加 -s,也不能直接用 a/an,但一些固定结构(如 percent、度量单位)例外,可以配数字使用。
副词修饰形容词的位置:famous nationwide 合法吗?
✅ 基础规则
- 副词修饰形容词时,通常放在形容词前:
- deeply impressed
- widely known
✅ 特殊情况:范围副词
一些表达范围/地点的副词(如 nationwide, worldwide, abroad)可以放在句末:
- ✅ He is famous nationwide.
- ✅ The singer became famous worldwide.
- ✅ She is known globally for her work.
✅ famous nationwide 和 nationally famous 都正确!
✅ 原句省略了关系从句:
完整句是:
→ Anyone who is willing to assist can contact this number.
✅ 类似结构:
- Anyone interested → Anyone who is interested
- Someone ready to help → Someone who is ready to help
- People tired of waiting → People who are tired of waiting
✅ 总结:
当形容词短语(如 willing to…)修饰人时,常可省略 “who is” / “who are”。
