精讲精练
知识点01：原句：Six years ago, Mike could read and draw, but he could not write.六年前，迈克会读书和画画，但是他不会写字。
【语法解析】
·could是can的过去式，意为“能够，会，可以”，表示某人具有做某事的能力；
其否定形式为couldn’t =could not;
·两者没有人称和数的变化，其后都要接动词原形。即
can/could + 动词原形
·肯定句型结构：主语 + could + 动词原形（+其他）.
否定句型结构：主语 + couldn’t + 动词原形（+其他）.
一般疑问句结构：Could + 主语 + 动词原形（+其他）？
肯定回答：Yes, 主语+could./否定回答：No, 主语+couldn’t.
拓展：could也可以表示委婉、客气地提出问题或陈述看法，此时可以与can互换使用，但could的语气较can委婉，两者没有时态上的区别。
例如： When I was five years old, I could sing, but I couldn’t dance.
【牛刀小试】
