读音指导
字母组合er在非重点音节中，尤其是作为后缀时，常发短元音/ə/，如：teacher，wrker
拓展：字母组合er在重读闭音节中，常发长元音/ɜː/，如：term, her
culd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culdn’t =culd nt;
两者没有人称和数的变化，其后都要接动词原形。即can/culd + 动词原形
肯定句型结构：主语 + culd + 动词原形(+其他).
否定句型结构：主语 + culdn’t + 动词原形(+其他).
一般疑问句结构：Culd + 主语 + 动词原形(+其他)?
肯定回答：Yes, 主语+culd./否定回答：N, 主语+culdn’t.
拓展：culd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culd的语气较can委婉，两者没有时态上的区别。
典例：When I was five years ld, I culd sing, but I culdn’t dance.
当我五岁的时候，我会唱歌，但是我不会跳舞。

以“辅音字母+y”结尾的动词，变y为i，再加es, 如：fly--flies;
特例：have--has
注：当主语是he, she, it以及单数，不可数名词时用三单。
