Grammar Rule in 30 Seconds
Start with what your listener knows (Theme) and end with the exciting new information (Rheme) to ensure perfect flow.
- Place 'Given' information at the start of the sentence to provide context (e.g., 'The house...').
- Place 'New' information at the end of the sentence for emphasis (e.g., '...was built in 1920').
- Use the passive voice or cleft sentences to shift information into the correct position for flow.
Overview
- 1提升学术写作的连贯性：在撰写论文或商务报告时，确保上一句的末尾（Rheme）与下一句的开头（Theme）有逻辑关联。例如：
The company launched a new app. This app changed the market.这里的“This app”就是完美的主位衔接。
- 1增强修辞效果：当你想要强调某种背景时，使用有标记主位。例如：
In the middle of the night, a loud noise woke me up.这种结构比A loud noise woke me up in the middle of the night更有画面感，因为它先铺陈了时间背景。
- 1职场沟通中的重点突出：在给老板发微信或邮件时，将你最想强调的结论放在句子的最后（Rheme），因为英语中句末位置具有“末端重心”（End-focus），听者或读者会给予此处最高程度的注意力。
- 1句首堆砌新信息（L1干扰）：中文习惯把长定语放在主语前，例如“那个昨天我在淘宝上买的红色手机坏了”。如果直接翻译成
The red phone I bought on Taobao yesterday broke，对于英语母语者来说，开头太沉重。建议改为：My new phone broke; it's the one I bought on Taobao.拆分句子，平衡信息量。
- 1滥用被动语态：许多学习者认为被动语态高级，但如果不考虑主位，会显得生硬。只有当你想把受事者（Patient）作为已知信息（Theme）时，才使用被动语态。不要为了用而用。
- 1忽视逻辑连接词的主位功能：中文连接词常省略，但英语中
However,Therefore,In addition作为文本主位非常关键，它们直接告诉读者：下一句信息的逻辑走向是什么。

Use 'It' as a dummy subject and move the long clause to the end.
Use an 'It-cleft' to put that person in the spotlight.
Ensure your first sentence (the Topic Sentence) has a clear Theme that connects to the overall theme of the text.
Vary your Themes. Don't start every sentence with 'I' or 'The company.' Use time phrases or adverbs as 'Marked Themes.'

常见问题 (8)
Not always, but in English, it usually is. When the Theme is not the subject (e.g., 'Yesterday, I went...'), we call it a 'Marked Theme.'
Because it looks at the *function* of the words in a conversation (what is known vs. what is new) rather than just their grammatical labels (noun, verb).
In complex sentences, yes. Each clause can have its own internal Theme/Rheme structure.
Absolutely. In speech, we use intonation to highlight the Rheme, but the word order still usually follows the Old-to-New pattern.
It's the principle that longer, more complex phrases should come at the end of a sentence to make it easier to process.
Ensure the Theme of your new sentence relates to the Rheme of the previous one. This creates a 'chain' of logic.
It's very effective for *introducing* a new subject for the first time. Once introduced, that subject becomes 'Old' info.
Yes, for specific effects. For example, 'Fronting' puts the new info first to surprise the reader (e.g., 'Incredibly, he won!').
