在英语中，"早餐吃饱了吗"可以用以下几种方式表达：
"Did you have a good breakfast?" 这是一个简单的问句，意思是"你早餐吃得好吗？"
"Are you full from breakfast?" 这是一个问句，意思是"你早餐吃得饱吗？"
"Did you eat enough breakfast?" 这是一个问句，意思是"你早餐吃得足够吗？"
"Were you satisfied with your breakfast?" 这是一个问句，意思是"你对早餐满意吗？"
这些表达都源自英语中的动词"have"、"eat"和形容词"full"、"enough"、"satisfied"。
下面是一些例句：
"I had a big breakfast this morning, so I'm pretty full." (我今天早上吃了一份大早餐，所以我很饱。)
"I didn't eat enough breakfast, so I'm still hungry." (我早餐吃的不够，所以我还是有点饿。)
"I wasn't very satisfied with my breakfast this morning. The toast was burnt and the coffee was too weak." (我对今天早上的早餐不是很满意。面包烤焦了，咖啡太弱了。)
