percents
类似结构

advice | ❌ | some advice |
tip | ✅ | a tip / some tips |

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!
句子分析:Anyone willing to assist can contact this number.
✅ 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”。
“start” 和 “begin”的区别
维度 | start | begin |
---|---|---|
语气 | 更口语、直接 | 更正式、文雅 |
使用频率 | 常见于日常 | 常见于正式、书面 |
搭配对象 | 机器、程序、活动 | 表演、旅程、演讲、进程 |
✅ 中文“你可以开始你的表演”常见英文表达:
- You can start your performance.(日常口语)
- You may begin your performance.(正式、庄重)
- The stage is yours.(主持风格,地道表达)
- Go ahead and begin.(鼓励+指令感)
📌 两者可以互换,但选择哪个更自然,要看语境。
玩梗场合:选 start 还是 begin?
✅ 正确选择:start
✅ 推荐句式(搞笑/玩梗风):
- You can start your performance.
- Now, start your performance.
- Go ahead, start your performance.
- You may now start your performance.(装模作样地正式)
❌ 不推荐:
- You can begin your performance.(太温和,不搞笑)
“when” 和 “while”的区别
词 | 用法 | 例句 |
---|---|---|
when | 强调时间点或时期 | When summer comes, bamboo mats are essential. |
while | 强调动作同时发生或对比 | While summer is hot, bamboo mats help keep people cool. |
你的表达
- 当表示“夏天来临时”用 when 更合适
- 当表示“夏天这段时间”或“两个动作同时发生”用 while
“唯物主义”和“物质主义”的英文区别:
中文 | 英文 | 说明 |
---|---|---|
唯物主义 | philosophical materialism | 哲学范畴,马克思主义哲学概念 |
物质主义 | materialism / materialistic values | 强调物质财富和消费的价值观 |
例句:
- Dialectical materialism is a core theory in Marxism.
- Materialism as a lifestyle has become more common in urban China.
地名、国家名使用所有格 ‘s 说明
用法 | 例句 | 说明 |
---|---|---|
国家名 + ‘s | China’s rural regions | 表示所属关系 |
of + 国家名 | rural regions of China | 另一种所属表达方式 |
地名直接修饰名词 | rural China | 形容词性质的短语,较少使用 |
小结
- 国家或城市名做所属关系时,常用
's
,更口语化 - 正式写作中,用 “of” 结构也非常常见且准确
常见英语后置定语表达(过去分词)

- We are reviewing the results obtained in the experiment.
- The company denied the charges filed against it.
- She responded to the complaints received last week.
✅ 小贴士:
- 普通形容词常前置:an important decision
- 分词作修饰(特别是过去分词)常后置:the decision made
✅ 过去分词是否等同形容词?
🧠 简要结论:
- 动词的过去分词可以作形容词用,词典常标为 adj.
- 但与“原生形容词”在语义、搭配、词序上存在细微差别
📘 原生形容词 vs 过去分词形容词
特点 | 原生形容词 | 过去分词形容词 |
---|---|---|
来源 | 本来是形容词 | 动词的过去分词形式 |
语义 | 描述属性 | 含有“被动 / 状态 / 完成”等动词语义 |
词序 | 常前置 | 多数只能后置(特别是结构复杂时) |
举例 | happy, important, large | concerned, involved, broken, known |
✳️ 举例对比:
- ✅ a happy child
- ✅ the people concerned
- ✅ the time wasted
- ✅ the questions asked by students
🔁 常见只能后置的表达:
- the people concerned(相关人员)
- the difficulties involved
- the plan proposed by the board
- the damage caused by the storm
✅ 结论:
- 分词作形容词 ✅ 是合法用法
- 但需要注意词序、搭配习惯、动词原义残留
