HSKReadyGet the appHSK 2 Fixed Expressions: Expressing the Immediate Future with 要/快要/就要……了
In Chinese, the fixed expressions 要……了, 快要……了, and 就要……了 indicate that an action or change of state is about to happen very soon. While they share the same core meaning, they differ significantly when you add a specific time word to the sentence.
要下雨了。
Uses 要……了 to announce an upcoming change in weather; the object 雨 stays before 了.
× 电影八点快要开始了。
In this schedule pattern, replace 快要 with 就要 before 开始. This is a date/time adverbial before an event, not a time predicate like 快要八点了.
Corrected example: 电影八点就要开始了。

Core Meaning and Syllabus Scope
When you want to say that something is about to happen, is going to happen soon, or is on the verge of changing in Mandarin, you do not rely on a verb tense suffix. Instead, Chinese uses a framing pattern that wraps around the predicate. In the supplied HSK 3.0 syllabus outline (edition 2025-11, implementation label 2026-07), the group 要/快要/就要……了 is classified at Level 2 under fixed formats and fixed phrases. Note that this level designation reflects the supplied reference outline rather than a guarantee of what version a particular test center currently administers.
In this frame, the first element (要, 快要, or 就要) sits directly before the verb or adjective to point forward in time, while the sentence-final particle 了 signals an upcoming emergence or change of situation. Learners often associate 了 with past actions, so it is helpful to remember that final 了 marks a new situation. When combined with 要, 快要, or 就要, that new situation is right on the horizon.
要下雨了。
Uses 要……了 to announce an upcoming change in weather; the object 雨 stays before 了.
公共汽车快要到了。
Uses 快要……了 without a specific time word to emphasize that the arrival feels very close.
Basic Sentence Structure
When no specific point in time is mentioned, all three options work in the same basic slot. The subject comes first, followed by 要, 快要, or 就要, then the verb phrase or adjective, and finally 了 at the end of the clause. If the verb takes an object, such as rain in下雨 or class in上课, the object stays inside the frame before 了.
Without a stated date, all three can present an approaching event. 要 is relatively neutral, while 快要 stresses nearness and 就要 can stress that the event is soon or already on the horizon. These are tendencies, not a fixed ranking in seconds or minutes: 下个月就要毕业了 can refer to next month.
就要上课了，请大家坐好。
In this context, 就要...了 presents class as about to begin; the request to sit adds urgency.
Crucial Contrast: Adding Specific Time Words
Although the three expressions look interchangeable in simple sentences, they behave very differently when you include a specific time word or time phrase (such as tomorrow, eight o'clock, or next month). If you want to state the exact time when an imminent event will take place, 就要……了 is the standard and most natural choice.
飞机十点就要起飞了。
The specific time word 十点 sits after the subject and directly before 就要.
For a scheduled event with a stated date or clock time before the event clause, use 要 or 就要 in these beginner examples. Distinguish that scheduling phrase from a time/quantity predicate after 快要: 快要八点了 (“It is almost eight”) is possible.
姐姐下个月要毕业了。
Uses 要……了 with the time phrase 下个月 to state an approaching milestone.
- 就要……了: Freely combines with specific time words placed before 就要.
- 要……了: Can combine with future time words to state when an upcoming event will occur.
- 快要...了: focuses on an approaching event; in the scheduling examples here, use 要/就要 with a stated date before the event clause.
Common Learner Mistake and Limits
In the schedule pattern 电影八点...开始了, use 就要 rather than 快要. Learn this as a constructional contrast; it does not follow simply from translating 快 as “fast”. A phrase such as 快要八点了 has a different structure and is possible.
× 电影八点快要开始了。
In this schedule pattern, replace 快要 with 就要 before 开始. This is a date/time adverbial before an event, not a time predicate like 快要八点了.
Corrected example: 电影八点就要开始了。
电影八点就要开始了。
就要...了 accepts the scheduling phrase 八点 before the event predicate here.
There are two more practical limits to keep in mind when using these phrases:
- Do not form “not about to” by mechanically inserting 不 before 要; 不要 can instead be a prohibition. To say an event has not happened yet, use 还没 + verb phrase, often with 呢. A negative predicate can occur inside an approaching-change frame: 快要没钱了 means “about to run out of money”.
- Distinguish intention from imminence: When 要 is used with a human subject, context determines whether it means wanting/planning to do something or being about to do it. Adding 了 at the end of the sentence shifts the focus toward an imminent change of state, whereas omitting 了 usually expresses personal intention or obligation.
Frequently asked questions
Why is 了 used here if the action has not happened yet?
Sentence-final 了 does not mark past tense; it marks a change of state or a new situation. When paired with 要, 快要, or 就要, it indicates that a new state is about to begin.
Where does the object go in a 要/快要/就要……了 sentence?
The object goes after the verb and before the final 了, such as 雨 in 要下雨了 or 课 in 就要上课了.
Is 快……了 the same as 快要……了?
Often, for an approaching event: 电影快开始了 and 电影快要开始了 both work. They share the scheduling contrast illustrated above. Do not extend it to a time predicate such as 快要八点了, which is also possible.
