要是……就…… Everyday Condition in Chinese
要是……，就……
要是……就…… introduces an everyday spoken condition and its expected result. 要是 opens the condition, while 就 normally appears before the result predicate or after the result-clause subject. The construction is close to 如果……就…… but is especially common in conversation and does not itself imply a feared outcome.

Read the structure
要是……就…… introduces an everyday spoken condition and its expected result. 要是 opens the condition, while 就 normally appears before the result predicate or after the result-clause subject. The construction is close to 如果……就…… but is especially common in conversation and does not itself imply a feared outcome. Keep the model 要是 + Condition，Subject + 就 + Result visible while you compare each sentence.
要是明天下雨，我们就不去了。
If it rains tomorrow, we will not go.
Choose the right context
State an everyday condition and its expected result. Place 就 after the result-clause subject when that subject is overt. Use the pattern for plans, advice, warnings, or predictions.
要是你累了，就休息一会儿。
If you are tired, rest for a while.
Respect the boundary
Do not place 就 inside the unfinished 要是 clause. Do not assume the condition must be undesirable. Do not confuse 要是 with the verb 要 meaning want.
要是就明天下雨，我们不去了。
(If then tomorrow rains, we do not go.)
Repair the pattern
就 appears before the condition: The condition follows 要是; 就 belongs with the result clause rather than before the condition predicate. The result is left incomplete: The result clause needs a predicate after 就 in this standalone sentence.
要是明天下雨，我们就不去了。
Use the repaired structure without changing the intended meaning.

要是你累了，就休息一会儿。
If you are tired, rest for a while.

05 / REPAIR
Compare Right and Wrong
Compare the smallest meaningful change. Each explanation identifies a placement, scope, form, or clause relationship instead of treating the whole sentence as one undifferentiated mistake.
要是就明天下雨，我们不去了。
要是明天下雨，我们就不去了。
就 appears before the condition
The condition follows 要是; 就 belongs with the result clause rather than before the condition predicate.
要是你累了，你就。
要是你累了，你就休息一会儿。
The result is left incomplete
The result clause needs a predicate after 就 in this standalone sentence.
要是就明天下雨，我们不去了。
The condition follows 要是; 就 belongs with the result clause rather than before the condition predicate.
要是你累了，你就。
The result clause needs a predicate after 就 in this standalone sentence.
06 / PRACTICE
Practice the Grammar Point
Complete three short tasks in order: judge the pattern, repair a common error, and build the sentence. Feedback is fixed and reviewed, so these activities do not use a checker allowance.
1. Judge the sentence
2. Choose the correction
3. Build the sentence
Build a complete sentence with 要是……，就…….
07 / APPLY
Apply It in Your Sentence
Write one original sentence with 要是……，就……. Your draft moves to the checker through this browser session, selects this grammar point as the first review focus, and waits for you to submit.
08 / QUESTIONS
要是……就…… Everyday Condition Questions
Is 要是……就…… different from 如果……就……?
Their core condition-result meanings overlap. 要是 is especially common in conversation, while 如果 is broadly neutral across spoken and written contexts.
Can 就 be omitted?
Yes, when the relationship is already clear. Keeping 就 is useful for making the consequence explicit and for practising standard result-clause word order.
