Grammar Rule in 30 Seconds
Use past participles to replace 'which was' or 'because it was' for elegant, professional, and concise English writing.
- Drop the subject and 'be' verb: 'The book, which was written in 1920' becomes 'Written in 1920'.
- Ensure the subjects match: The person/thing doing the action in both clauses must be identical.
- Use for reasons or descriptions: 'Shocked by the news, she fainted' (Because she was shocked).
Overview
broken, written, taken）本身就自带“被动”和“已完成”的属性。当它被用作分词短语时，它实际上是一个“缩水版”的从句。which, who, that）和 be 动词后的产物。- 全句：

Start the sentence with the -ed participle to immediately set the mood.
Combine them by turning the first one into a participle clause.
Replace 'If it is...' with the past participle for a more concise, 'instruction manual' style.
发音
Comma Pause

Introductory Clause

文化笔记
In Western academia, using participle clauses is seen as a sign of high literacy and objective 'distancing' from the subject.
News headlines often omit the 'be' verb entirely to save space, creating 'headlinese' which is essentially a participle clause.
Contracts use these to define terms precisely without repeating the subject.
These structures evolved from Latin 'Absolute' constructions, which were heavily used in legal and religious texts.

常见问题 (8)
It's a common mistake where the participle clause describes the wrong subject. For example, `Walking to the store, the rain started.` implies the rain was walking. You must ensure the subjects match.
Yes, but they sound quite formal. In casual conversation, we usually use `because` or `so`. You might hear them in speeches or formal presentations.
`Seen` describes a state or simultaneous action. `Having been seen` emphasizes that the action was completed *before* the main verb happened.
If the clause comes at the beginning, yes. If it follows the noun it describes (e.g., `The car stolen yesterday...`), you usually don't need a comma unless it's non-defining information.
Yes! Just put `not` at the very beginning. `Not surprised by the news, she continued her work.`
Because the subject of the sentence is the *receiver* of the action in the participle clause. `Struck by lightning, the tree fell` (The tree was struck).
Only with transitive verbs (verbs that take an object) because only they can be made passive.
Yes, `Given the circumstances...` is a very common fixed participle clause used to mean 'Considering the circumstances'.
