英语翻译问题!

stay in bed就是待在床上，可能是睡觉，可能就躺着，反正就是在床上

他待在床上直到午餐时间。
（stay in bed:待在床上：躺在床上；译为睡觉）
出自新概念英语第二册，嘿嘿，我学过
原文：It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunchtime. Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy. 'I've just arrived by train,' she said. 'I'm coming to see you.'
'But I'm still having breakfast,' I said.
'What are you doing?' she asked.
'I'm having breakfast,' I repeated.
'Dear me,' she said. 'Do you always get up so late? It's one o'clock!'

译文：
那是个星期天，而在星期天我是从来不早起的，有时我要一直躺到吃午饭的时候。上个星期天，我起得很晚。我望望窗外，外面一片昏暗。“鬼天气！”我想，“又下雨了。”正在这时，电话铃响了。是我姑母露西打来的。“我刚下火车，”她说，“我这就来看你。”
“但我还在吃早饭，”我说。
“你在干什么？”她问道。
“我正在吃早饭，”我又说了一遍。
“天啊，”她说，“你总是起得这么晚吗？现在已经1点钟了！”
