As to meaning: II. As to Form:1. Declarative Sentence 1. Simple Sentence2. Interrogative Sentence 2. Compound Sentence（并列）3. Imperative Sentence 3. Complex Sentence （复合）4. Exclamatory Sentence 4. Compound –Complex SentenceRhetorical Classification of SentencesIII. As to Arrangement1. Periodic Sentence （圆周句）left-branching sentence2. Loose Sentence（松散句）right-branching sentence3. Balanced Sentence4、The short and long sentence①Short sentences, on the whole, are characterized by their brevity, quick tempo and force. The short sentence is relatively simple in form, clear in grammatical relation, and terse and forceful in style.②Long sentence is relatively complex in form, fully expressive in capacity, and often used in formal style to show one’s complicated mentality or various kinds of relationship of different things.5、the simple，compound and complex sentence①A Simple sentence has only one clause to make a statement, and so it is good for directness and clearness.②The Compound Sentence consists of two or more independent clauses which are of equal status, that is, the clauses are paratactic (parallel; coordinate) in relationship.③The complex sentence makes clear the logical relationship between events or ideas through subordination. Subordinate clauses are named according to their functions.Left-branching sentence(periodic sentence)：*6、the branching sentencesRight-branching sentence（loose sentence）：Left-branching sentence(periodic sentence)：the periodic sentence has its main idea at the end of the sentence.supportive or qualifying information are placed before the main clause or assertion. Right-branching sentence（loose sentence）：in a loose sentence, the main idea is put at the beginning of the sentence,and supportive or qualifying information comes from it.*7、Balanced sentence：When a sentence contains tow parallel clauses similar in structure butcontrasted in meaning,it is balanced sentence.The main ideas are often presented in parallel phrases or clauses.⑴Parallelism排比：the main function of parallelism is to add clarity and coherence to what one wishes to communicate。

⑵Antithesis对比：antithesis is the deliberate arrangement of contrasting words or ideas in balanced structural forms to achieve force and emphasis。

⑶Chiasmus回文and antimetabole交叉：chiasmus is a device that consists of two balanced statements，the second of which reverses the order of the words in the first，with or without a repetition of words。

For example：①we eat for live，not live for eat。

（here the key words in the first statement are repeated，and reversed in order in the second。
