Overview
for example、such as 和 like 虽然在功能上相似，却有着截然不同的语法属性、正式程度和逻辑内涵。很多母语为中文的学习者在雅思、托福作文甚至高端商务沟通中，常常会因为混淆这三者而显得表达不够地道，甚至出现语法错误。- 1
For example是副词短语 (Adverbial Phrase)：
- 1
Such as是介词短语 (Prepositional Phrase)：
- 1
Like在引出例子时也是介词 (Preposition)：
such as，但在 C1 级别的学术写作或正式报告中，like 往往被认为不够严谨。它更像中文里的“像……这种”。For example倾向于引出一个完整的观点或事件。Such as倾向于列举名词列表，且语气正式。Like倾向于非正式的类比或随意列举。
- 句首用法 (Sentence-initial): 这是最常见的用法。后面必须加逗号。
The company faced many challenges. For example, the global chip shortage delayed production.- *中文逻辑：* 公司面临很多挑战。例如，全球芯片短缺延误了生产。（注意：英语中
For example之后通常是一个完整的句子。） - 句中插入 (Mid-sentence): 这种用法更具文学性或高级感，通常用双逗号隔开。
Some industries, for example, the tourism sector, were hit hard by the pandemic.- *结构：*
[名词], for example, [例子], [谓语]... - 句末用法 (Sentence-final): 较少见，用于补充说明。
You should include more data in your report, for example.
Such as 的标点规则取决于它引出的信息是“必要的”还是“补充性的”：- 限制性用法 (Restrictive - 不加逗号): 如果例子是定义该类别所必需的，则不加逗号。
Programming languages such as Python and Java are essential for data scientists.- *解析：* 这里
such as明确了是“哪类”编程语言，不能省略。 - 非限制性用法 (Non-restrictive - 加逗号): 如果例子只是额外的补充，则前面加逗号。
Many Asian cities, such as Tokyo and Shanghai, have world-class subway systems.- *解析：* 即使去掉
Tokyo and Shanghai，主句“很多亚洲城市拥有世界级地铁”依然成立。
Like 的用法相对简单，通常直接放在名词后面，不需要复杂的标点。I prefer refreshing drinks like iced Americano or fruit tea.- *注意：* 在正式写作中，尽量将
like替换为such as。
For example | 副词短语 | 句首、句中、句末 | 句首后加逗号；句中用双逗号 |Such as | 介词短语 | 紧跟名词后 | 补充说明加逗号；定义类别不加 |Like | 介词 | 紧跟名词后 | 通常不加逗号 |for example。它给读者一个“暂停”的信号，提示接下来的内容是用来证明前面的观点的。- 场景： 雅思写作、商务报告、正式演讲。
- 例子：
Remote work offers flexibility. For example, employees can save hours of commuting time every day.(这里引出的是一个完整的因果逻辑，而非简单的名词列举。)
such as 是最佳选择。它在学术论文和法律文件中是标准用法。- 场景： 学术论文、技术文档、说明书。
- 例子：
The app supports various payment methods, such as WeChat Pay, Alipay, and credit cards.(这里是在界定支付方式的范围。)
like 显得更亲切、自然。此外，当你想强调“像……一样”的相似性时，like 比 such as 更合适。- 场景： 朋友聚会、社交媒体、非正式职场沟通。
- 例子：
I need a vacation to a place like Sanya or Bali.(这里强调的是“像三亚或巴厘岛那样的地方”，侧重氛围的相似。)
Such as 引导独立句子 (The Sentence Fragment)- 错误：
I like many Chinese festivals. Such as Spring Festival and Mid-Autumn Festival. - 原因： 在中文里，我们可以说“我喜欢很多中国节日。比如春节和中秋节。”但在英语中，
Such as是介词，不能独立引导一个句子。它必须依附于前面的主句。 - 修正：
I like many Chinese festivals, such as Spring Festival and Mid-Autumn Festival.或者使用For example:I like many Chinese festivals. For example, I enjoy Spring Festival...
For example 与 Such as 混用导致语法缺失- 错误：
Many tech giants for example Huawei and Tencent are investing in AI. - 原因： 这里
for example被当成了介词使用。如果要在名词后直接加例子，应该用such as。 - 修正：
Many tech giants, such as Huawei and Tencent, are investing in AI.
etc. 或 and so on- 错误：
We sell fruits such as apples, oranges, etc. - 原因：
Such as本身就暗示了这只是一个非穷尽的列表（不完全列举），后面再加etc.会显得语义重复（Redundant）。这是 C1 级别写作中非常低级的错误。 - 修正：
We sell fruits such as apples and oranges.
Like 在学术写作中的过度使用- 原因： 很多同学受美剧影响，习惯用
like举例。但在学术论文中，like更多表示“相似”而非“举例”。 - 修正： 在论文中，请将
like替换为such as或including。
Specifically | 强调接下来的例子非常具体 | 深入解释某个细节时 |To illustrate | 比 for example 更正式，带有“描绘”感 | 演示复杂理论或长篇论述 |A case in point is... | 极度正式，引出一个非常典型的个案 | 辩论、学术论文、法律陈述 |Notably | 强调例子中的“显著性” | 突出最重要的例子时 |Including | 强调例子是整体的一部分 | 侧重于包含关系时 |Standard:We need to improve our service. For example, we should respond to emails faster.
Advanced (C1):We need to enhance our service quality; to illustrate, a more responsive email protocol would significantly boost client satisfaction.
e.g. 和 for example 有什么区别？e.g. 是拉丁语 exempli gratia 的缩写，意思就是 for example。在现代英语中，e.g. 主要用于书面记录、括号内说明或非正式笔记。在正式论文的正文中，建议拼写出完整的 for example 或使用 such as。记得 e.g. 后面通常也要加逗号。Such as 吗？Such as 必须紧跟在它所修饰的类别名词后面。如果你想在句首举例，请使用 For instance 或 For example。唯一的例外是极少数文学修辞，但在 C1 级别的学术或商务写作中，应视其为禁忌。For instance 和 For example 有区别吗？For instance 稍微正式一点点，且更倾向于引出一个“具体的事件”或“实例 (Instance)”，而 For example 则更通用。在写作中交替使用这两者可以避免词汇重复。such as 吗？Such as 暗示这只是部分例子。如果你要列举全部，请使用 namely（即）或 consisting of（由……组成）。例如：The United Kingdom consists of four countries: England, Scotland, Wales, and Northern Ireland. 这里不能用 such as，因为你已经把四个都说完了。for example），还是在列举类别成员（用 such as），抑或只是在做非正式的类比（用 like）？精准的标点和正确的句法结构，将让你的英语表达瞬间提升一个档次。Placement and Punctuation of Exemplifiers

常见问题 (8)
It is generally discouraged. Use `such as` or `for instance` instead to maintain a formal tone.
`e.g.` stands for 'exempli gratia' (for example), while `i.e.` stands for 'id est' (that is). Use `e.g.` for a list of examples and `i.e.` for a definition or clarification.
Yes, when it starts a sentence or follows a semicolon, a comma is required to set it off from the rest of the sentence.
They are very similar, but `for instance` is often perceived as slightly more formal or sophisticated in professional writing.
Generally, no. `Such as` is a prepositional phrase that should follow the noun it is illustrating. Use `For example` to start a sentence.
Because `such as` already indicates that you are providing a partial list. Adding `etc.` is repetitive and considered poor style.
The correct phrase is `such as`. `Such like` is non-standard and should be avoided.
The comma goes *before* `such as`, never after it. For example: 'I like fruit, such as apples.'
