dinner和supper常见错误：
1、dinner：
我们邀请他来吃饭好吗?
错误 Shall we ask him to the dinner?
正确 Shall we ask him to dinner?
分析： to dinner是固定用法,不能加定冠词the。像这样的短语还有at dinner, before dinner, after dinner等。
2、supper：
昨天我吃了一顿很棒的晚饭。
错误 I had wonderful supper yesterday.
正确 I had a wonderful supper yesterday.
分析 supper作“晚饭”解泛指一顿饭的名称时,前面通常不加冠词; 但当有定语修饰时,前面通常加不定冠词a。
supper：n.晚饭，晚餐； 夜点心； 晚餐会。
dinner：n.正餐，主餐； 宴会； 晚餐。
区别：“supper”主要指的是晚餐，而“dinner”指的是正餐。
