这就是我们一家的一日三餐的英语怎么说

"One's daily three meals" in English is commonly referred to as "breakfast, lunch, and dinner." The origins of these terms come from the words "break" (to break the fast of the night) for breakfast, "lunch" (a shortened version of "luncheon," a meal taken in the middle of the day) for lunch, and "dinner" (from the Old French "disner," meaning to dine) for the evening meal.

Examples:

I always have a big breakfast before going to work. (我总是在去上班前吃一顿大早餐)
Let's meet for lunch at noon. (我们中午12点见面吃午饭)
We're having guests over for dinner tonight. (我们今晚有客人来吃晚饭)
