只有…才…
Only if/only…, (then)…
HSK 4HSK 3.0 · 3
只有 + condition (the only one),(S) + 才 + result
只有…才… states the ONLY, necessary condition: without A there is no B. The second clause must use 才 (after the subject, before the verb), never 就. 只有 can also precede a noun or pronoun subject: 只有他才知道 'only he knows'. 才 sentences do not end in 了. Compare: 只要 = as long as (easy), 只有 = only if (no alternative).
