高中英语中，句子结构复杂多样，但基本上都包含主语、谓语和宾语。

1. 简单句：只有一个主语和一个谓语。例如：I love English.2. 并列句：有两个或以上的主语和谓语，用连词连接。例如：I love English, and she loves math.3. 复合句：由主句和从句组成，从句可以是名词性从句、形容词性从句或副词性从句。例如：He said that he was tired. (名词性从句)The book, which was written by a famous author, is very interesting. (形容词性从句)I will study hard so that I can get a good grade. (副词性从句)4. 倒装句：将谓语动词提到主语之前，或将助动词或情态动词提到主语之前。例如：Never have I seen such a beautiful sunset. (部分倒装)Not only does he play basketball well, but also he excels in football. (全部倒装)5. 强调句：通过强调某个词或短语来表达强烈的感情或重要的意义。例如：It was John who won the first prize. (强调主语)I did finish my homework last night. (强调谓语)总之，理解句子结构是理解英语语法的基础，能够帮助我们更好地理解阅读材料，提高听、说、读、写能力。
