Analysis:

Sentence is the basic unit of language use, which consists of words and phrases (phrases) and can express a complete meaning, such as telling someone something, asking a question, asking or stopping, expressing some emotion, and indicating the continuation or omission of a paragraph. There is a big pause between sentences. It should end with a period, question mark, ellipsis or exclamation point.

In order to express the meaning clearly, commonly used sentences include two parts: one part is the "who" or "what" said in the sentence (subject part); The other part is "what", "how" or "what to do" (predicate part) in the sentence.

Sentence pattern:

According to the structure, sentences can be divided into simple sentences and complex sentences, and simple sentences can be divided into subject-predicate sentences and non-subject-predicate sentences. According to the nature of predicates, subject-predicate sentences can be divided into verbal predicate sentences, adjective predicate sentences, nominal predicate sentences and subject-predicate sentences.

Non-subject-predicate sentences are divided into verbal non-subject-predicate sentences, adjective non-subject-predicate sentences, nominal non-subject-predicate sentences, exclamatory non-subject-predicate sentences and onomatopoeic non-subject-predicate sentences. See section 9 for complex sentences. The following focuses on the analysis of subject-predicate sentences and several special verb-predicate sentences.
