Formal High Degree with 极为 in Chinese
极为
极为 is a formal degree adverb meaning extremely or highly. It normally precedes an adjectival or stative predicate in reports, evaluations, and careful prose. The two-character adverb forms one unit: aspect particles cannot split it, and it cannot be moved after the predicate as though it were a degree complement.

极为 is a formal degree adverb meaning extremely or highly. It normally precedes an adjectival or stative predicate in reports, evaluations, and careful prose. The two-character adverb forms one unit: aspect particles cannot split it, and it cannot be moved after the predicate as though it were a degree complement. Keep the model Subject + 极为 + Adjectival Predicate visible while you compare each sentence.

Choose the right context
Use 极为 before a formal adjectival evaluation. Use it to mark a very high degree in expository prose. Let it scope over the complete following predicate.
当地的生态环境极为脆弱。
The local ecosystem is extremely fragile.
Respect the boundary
Do not split 极为 with a particle. Do not place 极为 after its adjective. Do not attach perfective 了 directly to this adverb.

Repair the pattern
Particle splits the degree adverb: 极为 is an indivisible degree adverb; 了 cannot occur inside it. Degree adverb follows the adjective: 极为 must precede the adjectival predicate it modifies.
