HSKReadyGet the appHSK 4 Fixed Phrase: Verb + 一X是一X
The fixed pattern Verb + 一X是一X expresses a practical attitude when facing a large task or limited resources: every single unit completed, saved, or gained counts as solid progress.
咱们省一分是一分。
Here 省 (shěng, to save) is followed by the repeated money unit 分 (fēn, cent).
× 时间不够了，背一个生词是一个句子。
Incorrect: In this context of incremental progress, the two X slots cannot contain different nouns (生词 vs. 句子). See “时间不够了，生词能背一个是一个。” for the natural replacement.
Corrected example: 时间不够了，生词能背一个是一个。

Core Meaning and Syllabus Scope
In the supplied HSK 4 grammar outline, 动词+一X是一X is listed as a fixed phrase under fixed patterns. Note that this level tag reflects the local syllabus document rather than a guarantee about which exam version a specific test center currently administers.
Speakers use this pattern when a goal feels large, time is tight, or resources are scarce. Instead of worrying about completing everything at once, the speaker focuses on immediate, tangible gains. In English, it often translates to 'every bit you [verb] counts' or 'each one [verbed] is one gained or taken care of.'
咱们省一分是一分。
Here 省 (shěng, to save) is followed by the repeated money unit 分 (fēn, cent).
Structure and Component Slots
- The verb is only provided once at the very beginning of the phrase; it is not repeated after 是 (shì).
- Short action verbs are common, such as 省, 记, 做, 卖 and 帮. A longer verb or result expression can also fit when the unit makes sense, as in 完成一项是一项 (“each task completed counts”).
- The X slot is filled by a measure word (classifier), a time or money unit, or occasionally a short measure-plus-noun combination. Both X slots must be identical.
生词很多，考试前能记一个是一个。
Preceded by 能 (néng), showing a practical effort under time pressure.
Natural Contexts and Pragmatic Tone
A constraint such as a deadline or limited resources often explains why the speaker focuses on one unit at a time. In savings or learning contexts this can be encouraging. In an expression such as 过一天是一天, the same one-unit focus can sound resigned or show that someone is only getting by; tone depends on the whole context.
活儿太多了，做一件是一件吧。
Uses 件 (jiàn), the measure word for tasks or matters.
Structural Limits and Learner Mistakes
In the basic model, the repeated unit refers to the same thing: one more word remembered, one more task completed or one more cent saved. If the second unit changes from “word” to “sentence”, it no longer expresses that intended incremental meaning. Practice the simple unmarked verb frame first; aspect and negation in other sentence constructions should be judged in their own context.
× 时间不够了，背一个生词是一个句子。
Incorrect: In this context of incremental progress, the two X slots cannot contain different nouns (生词 vs. 句子). See “时间不够了，生词能背一个是一个。” for the natural replacement.
Corrected example: 时间不够了，生词能背一个是一个。
时间不够了，生词能背一个是一个。
Correct replacement for “时间不够了，背一个生词是一个句子。”: both X slots use the identical classifier 个 (gè).
Useful Contrasts
In casual conversation, you will also hear 动词+一X算一X, where 算 (suàn, to count as) replaces 是 (shì). Both expressions share the same core meaning in contexts of limited capacity. Using 是 sounds slightly more assertive that the result is a solid, undeniable gain, whereas 算 explicitly highlights the idea of tallying or settling for whatever number you can manage.
能帮一个算一个。
A close conversational parallel using 算 (suàn) instead of 是 (shì).
Do not confuse this use with 说一是一 (“keep one’s word / mean what one says”) or 一是一，二是二 (“be precise and clear about what is what”). 说一是一 itself begins with the verb 说, but its established meaning is different from counting each small gain.
Frequently asked questions
Do I repeat the verb after 是 in 动词+一X是一X?
No. The verb appears only once at the start of the phrase. After 是, you only repeat 一 and the unit X.
Can I replace 一 (yī) with other numbers like 两 (liǎng) or 三 (sān)?
The outline’s one-unit pattern uses 一 in both positions. Learn that model first. Other parallel expressions can use a different quantity, such as 省两块是两块 (“saving two yuan still counts”); this changes the quantity and is not inherently ungrammatical.
