Questions & Answers about yóuyú kuāndài duànwǎng le, yīncǐ jìshùrényuán jīntiān huì lái.
Why does the sentence use both 由于 and 因此? Don’t they both mean because / therefore?
Yes, they work together as a cause → result pair.
- 由于 introduces the cause: 由于宽带断网了 = because the broadband is down
- 因此 introduces the result: 因此技术人员今天会来 = therefore the technician(s) will come today
This pairing is fairly formal and very clear in written Chinese.
You can think of it like:
- 由于 X，因此 Y = Because of X, therefore Y
In English, using both because and therefore in one sentence can sound heavy, but in Chinese this pattern is normal, especially in formal writing.
Can I omit either 由于 or 因此?
Yes.
All of these are possible:
- 由于宽带断网了，技术人员今天会来。
- 宽带断网了，因此技术人员今天会来。
- 因为宽带断网了，所以技术人员今天会来。
- 宽带断网了，技术人员今天会来。
Using both 由于 and 因此 makes the relationship especially explicit and a bit more formal.
