小升初英语专题复习 陈述句的构成与句式变化 知识点归纳及专项练习（附答案解析） 一、知识点归纳 （一）陈述句的构成 陈述句一般用于陈述事实或者说话人的看法。包括肯定句和否定句两种形式。陈述句在书写时句末用句号，朗读时降调。 如：I’m a student.→ I’m not a student. I’m a teacher.→ I’m not a student. I like reading.→ I don’t like reading. I like cats.→I don’t like cats. 陈述句一般由主语、谓语动词、宾语、补语、状语等成分构成。 主语一般包括名词或名词性短语、人称代词（I、you、he、she等）、指示代词（this、that）等。 谓语动词指的是在句子中可以单独作谓语的动词，一般指实义动词（like、eat等）。情态动词（can、should等）、be动词（am、is、are）和助动词（do、does等）只能协助主要动词一起构成谓语动词。 （二）句式变化 1.陈述句的肯定形式 结构 例句 主语+be动词+表语 This is my brother. She is kind and funny. 主语+实义动词（+宾语+其他） I study very hard. He often plays football after class. 主语+情态动词+动词原形（+其他） I can swim very well. She should finish her homework on time. 2.陈述句的否定形式 结构 例句 主语+be动词+not +表语 I’m not a teacher. They are not my new friends. 主语+助动词+not+实义动词原形（+宾语+其他） He doesn’t like maths.
