Grammar [HSK 1 · Sentence types › Sentence patterns › Simple sentences](https://hskready.app/en/grammar/hsk-1#hsk-1-g045) # HSK 1 Sentence Types: Non-Subject-Predicate Sentences (非主谓句) In Mandarin Chinese, not every complete sentence divides into a subject and a predicate. Non-subject-predicate sentences (非主谓句) are standalone single-clause sentences formed by a single word or phrase—such as a verb phrase, adjective phrase, or noun phrase—that express a complete meaning in a clear real-world situation. Verb or Verb-Object Phrase 。 Example sentence 下雨了。 Xià yǔ le . It's raining. / It has started to rain. A verbal non-subject-predicate sentence describing a natural phenomenon without a grammatical subject. **Read the full explanation and examples** ## What Is a Non-Subject-Predicate Sentence? Within the HSK 1 grammar syllabus, single sentences (单句) are divided into two main structural categories: subject-predicate sentences (主谓句) and non-subject-predicate sentences (非主谓句). While a subject-predicate sentence clearly states who or what is being talked about (the subject) and what happens or is true about it (the predicate), a non-subject-predicate sentence consists of a single structural unit that cannot be split into those two parts. English speakers are often taught that every complete sentence requires an explicit grammatical subject, forcing English to use placeholder words like 'it' in 'It is raining.' Mandarin does not require a dummy subject. When the immediate environment makes the meaning completely clear, a standalone phrase with appropriate sentence intonation and punctuation is a fully grammatical, standard sentence. ## Verbal Non-Subject-Predicate Sentences: Weather and Polite Directives The most common non-subject-predicate sentences at HSK 1 level are built around a verb or verb-object phrase. These occur primarily in two everyday situations: describing natural or weather phenomena happening right now, and giving direct, polite instructions or invitations where no specific subject needs to be named. Verb or Verb-Object Phrase 。 下雨了。 Xià yǔ le . It's raining. / It has started to rain. A verbal non-subject-predicate sentence describing a natural phenomenon without a grammatical subject. 请进！ Qǐng jìn ! Please come in! A polite directive formed by a standalone verb phrase used when welcoming someone at the door. In the weather statement, the verb 下 (xià, to fall) takes the noun 雨 (yǔ, rain) as its object, and 了 (le) marks a new situation. There is no missing subject; the event itself is the entire message. Similarly, in polite directives such as inviting someone through a door or asking someone to sit down, the verb phrase stands alone naturally. ## Exclamations, Addressing People, and Conversational Formulas Beyond verb phrases, HSK 1 learners frequently use adjective phrases, noun phrases, and fixed routine expressions as complete non-subject-predicate sentences. These rely heavily on the shared physical context between speaker and listener. Degree Adverb / Modifier Adjective ！ 太好了！ Tài hǎo le ! That's great! / Wonderful! An adjectival non-subject-predicate sentence used as a direct exclamation reacting to a situation. Noun or Title ！ 王老师！ Wáng lǎoshī ! Teacher Wang! A nominal non-subject-predicate sentence used to call or greet someone directly. 谢谢！ Xièxie ! Thank you! A standalone polite formula that forms a complete sentence on its own. - Adjectival exclamations: Reacting immediately to good news, temperature, or taste using an adverb and adjective (such as 太好了！ or 很冷！). - Nominal calls and labels: Calling out a person's name or title to get their attention (vocative use), or naming an object you are pointing at. - Polite formulas and interjections: Standalone conversational routines like thanking, apologizing (对不起), or saying goodbye (再见) that function as independent sentences. ## Important Contrast: Non-Subject-Predicate vs. Omitted Subject vs. Subject-Predicate To use this sentence type accurately, you need to distinguish three things: a genuine non-subject-predicate sentence, a full subject-predicate sentence, and a conversational reply where the subject is simply left out (ellipsis). 北京今天下雨了。 Běijīng jīntiān xià yǔ le . It rained in Beijing today. / It is raining in Beijing today. In a common subject-predicate analysis, 北京 is the place subject, 今天 is a time adverbial, and 下雨了 is the predicate. Do not combine 北京今天 into a single subject, or assume that every initial time expression is a subject. The example 北京今天下雨了 can be analysed with 北京 as a place subject and 今天 as a time adverbial. The important distinction is the role a phrase plays, not merely its position. Adding a time expression to 下雨了 does not automatically create a subject: in 今天下雨了, 今天 may simply be a time adverbial. Do not confuse a non-subject-predicate sentence with an omitted subject in dialogue. If someone asks 'Did you buy apples?' and you reply '买了' (Bought them), your reply has a specific understood subject ('I') recovered from the question. In a true non-subject-predicate sentence like '下雨了。' or '太好了！', you do not need to supply a missing noun to make the grammar complete. ## Frequently asked questions **Why shouldn't I add 他 (tā) or 它 (tā) before 下雨了 to translate English 'It is raining'?** English it can fill a weather sentence's subject position without referring to an object. Chinese 它 normally refers to an identifiable nonhuman entity or idea in context; it is not the routine dummy subject of 下雨了. Use 下雨了 naturally, and add a place or time expression when needed without mechanically translating the English it. **Can a non-subject-predicate sentence be a question?** Yes. You can add a question particle like 吗 (ma) to a weather statement—for example, 下雨了吗？ (Is it raining now?)—or use rising intonation on a single noun phrase when offering something or checking identity. The sentence remains a non-subject-predicate sentence because it still has no subject-predicate split. **Are non-subject-predicate sentences considered slang or incomplete grammar?** No. They are a standard, officially recognized category of Chinese single sentences (单句). Weather statements, polite requests, signage, and exclamations are completely grammatical in both spoken and written Mandarin. **Source**[hsk.cn-bj.ufileos.com · PDF page 387](https://hsk.cn-bj.ufileos.com/3.0/%E6%96%B0%E7%89%88HSK%E8%80%83%E8%AF%95%E5%A4%A7%E7%BA%B21219.pdf#page=387) ## Continue in the app Full mock exams are available in HSKReady.
