Try starting your sentences in different ways
Not necessarily all declarative sentences（陈述句）.
• Declarative sentence: a statement that gives information
• Interrogative sentence（疑问句）: a question
• Imperative sentence（祈使句）: a command
• Exclamatory sentence（感叹句）: shows strong emotions or feelings
2. Varying sentence types改变句子类型
- Use simple sentences for emphasis（强调） and clarity（阐明）.
A simple sentence contains only one independent clause, but it is not necessarily short. It can have more than one subject, more than one verb, and several modifiers.
- Use compound sentences（并列句） to show relationships among equally important ideas.
• With a coordinating/correlative conjunction（关联词，并列连接词）

• With a semicolon（分号）

• With a semicolon and a conjunctive adverb（连接副词）

- Use complex sentences（复合句） to show that one or more ideas are less important than another idea.
- Use compound-complex sentences（并列复合句） occasionally to express complicated relationships.
3. Varying sentence length改变句子长度
- Use sentence length to achieve a specific effect.
• Short Sentences
— sharp and emphatic;
— definition, statements of weighty truth, or emphatic assertion.
• Longer sentences
—move the reader more slowly through the essay
—appropriate for description, explanation, or argument
A combination of long sentences and short ones is preferred.
