Learn to present two possible actions, choices, or outcomes with 或者……,或者……. See how the paired pattern works in statements and questions, and how its alternatives differ from actions happening at the same time.
The paired pattern 一会儿……,一会儿…… presents two or more actions or conditions that alternate over a period of time. Learn how to form it, when it sounds natural, and how it differs from describing two simultaneous actions.
Use 又…又… to combine qualities, states or actions in one description. Learn the repeated form and distinguish coordination from a claim about order, alternation or precise simultaneity.
一边……,一边…… connects two actions that happen at the same time or overlap. Learn where to place each half, how to use the pattern in statements and questions, and when a simpler sentence may be clearer.
Use 不但……,而且…… to connect two related facts and present the second as an additional, often stronger or more noteworthy point. Learn where to place the subject, how to form both clauses, and when simple addition is a better fit.
Use 虽然……可是…… to acknowledge a condition or fact, then show that the outcome differs from what someone might expect. Learn the two-part structure, how to avoid a mismatched contrast, and how this pattern works in everyday statements.
如果……,就…… is a common way to present a possible situation and say what follows if it happens. Learn how to form both parts, when 就 can be omitted, and how this pattern differs from nearby HSK 3 sentence types.
Use ……的话,就…… to name a possible situation and say what follows if it applies. Learn subject placement, how it overlaps with 如果……就……, and when 就 can be omitted.
Use 只有……,才…… to say that a condition is necessary for a stated result: the result happens only if that condition is met. Learn the word order, how to ask about necessity, and how this pattern differs from 只要……,就…….
只要……就…… presents a condition as enough for a result in context. Learn subject placement, the difference from 只有……才……, and why a past condition can still be relevant.
Use 为了 (wèile) before a goal to explain what someone does, plans, or chooses in order to achieve it. This lesson covers the pattern, natural contexts, and the key distinction between purpose and cause.
