Existential sentences (3): 存现句
In Chinese, existential sentences (存现句, cúnxiànjù) are used to describe the appearance, disappearance, or movement of people or objects at a specific location. These sentences always begin with a locative word or phrase in the subject position. In English, they are often translated using “There is/are...” or by placing the location at the beginning of the sentence (e.g., “From behind, two people walked past”).
Grammar Rules
1. Locative Word Starts the Sentence: The sentence begins with a location word (处所词语) acting as the topic or subject (e.g., 后边, 前面, 楼上).
2. Verb + Complement: The verb must be followed by a directional complement (趋向补语: 过来, 过去, 下来) or a result complement (结果补语). The aspect particle 了 (le) can be inserted to indicate completed action.
3. Indefinite Person/Thing: The person or object at the end of the sentence must be indefinite (unspecified to the listener). Therefore, it is always preceded by a numeral + measure word phrase (数量短语: 两个人, 很多车, 几个人).
