HSK 7
基于
jī yú
Based on
Explanation
"基于" (jī yú) is a preposition (a word placed before a noun indicating a relationship: at, with, for, etc.) used to state the basis, foundation, or grounds of a matter, action, or conclusion; it means "based on", "on the basis of". It carries a written (used in books and formal texts, seldom in speech), formal tone.
基于 (jī yú) + noun / noun phrase / verb phrase (serving as the basis). The phrase "基于…" usually serves as an adverbial (the element indicating time, place, or manner) placed before the predicate, or as the predicate after "是".
in argumentative writing, reports, and scientific reasoning, when presenting the grounds or premises leading to a judgment.
"基于" emphasizes the foundation/premise of an argument; "根据" (gēn jù) emphasizes concrete grounds or materials to act upon; "由于" (yóu yú) indicates cause. "基于" is more formal and abstract than "根据".
using "基于" right before a full clause with a long subject-predicate structure (it should be condensed into a noun/verb phrase); confusing "基于" with "基础" (jī chǔ, the noun "foundation") — "基于" is a preposition taking an object (the entity acted upon by the action).
