lunched

这组词均为餐名,一般不加冠词。它们的区别是：

dinner指正餐,多在晚上吃,也可指宴会; breakfast指早餐; lunch指午餐; meal指任何一餐; supper指晚餐; tea在英国,指下午茶。例如:

He asked me to dinner tonight.他邀请我今天晚上吃饭。

The dinner we had was excellent.我们吃的晚餐很丰盛。

I hope you will honour us with your presence at the dinner.我希望您能光临此次晚宴。

I have breakfast at seven.我在7点吃早餐。

We have lunch at noon.我们在中午吃午饭。

He had a light meal at home.他在家吃了顿便餐。

I have supper at six.我6点吃晚饭。

They are having tea in the garden.他们正在园子里喝下午茶。

这两个名词都含“午餐”之意。

lunch普通用词，系luncheon的略语。

luncheon比lunch正式而优，指在某一特定场合举行的非常正式的午餐。
