ABSTRACT
A subject-predicate sentence consists of a subject part and a predicate part; non-subject-predicate sentences consist of neither subject nor predicate. There are two types of non-subject-predicate sentences, one of which is without the subject and the other of which consists of a word or phrase. The former is called a sentence with no subject; the latter is called a single word/phrase sentence. For the latter, neither the subject nor the predicate can be functioned by this word or phrase. The sentence with no subject does not have any subject, mainly describing actions, behaviors, or changes, rather than narrating “who” or “what” related to them. It differs from the sentence with an omitted subject or with a hidden one. Usually, the sentence with no subject consists of a verb, based on which its adverbial and object can be parsed further. A single word/phrase sentence is also a complete one. It can express an independent or definite meaning without depending on the context.
