新概念英语第一册82课有几个句子的用法弄不清楚，请高手帮解答，谢谢。

谢谢、You had a good time、I had a glass of milk. 与 We went for a holiday last month. 与 You emjoyed yourself. 与 I drank a cup of coffee.
3.
4. 与 I drank a glass of milk.
21、They are having their lunch. 与 They ate a meal at a restaurant.
5？或者语法上面的区别.

以上每个句子中的两句话有什么用法上的区别、I had a cup of coffee、We had a holiday last month、They had a meal at a restaurant.
6. 与 They areeating their lunch

英语中的have 是个万能动词 与不同的名词搭配 就有不同的意思
你的以上每个句子中的两句话 都是同义句 用法和意思上几乎没有区别 后者比前者更具体一些

1.it took me two hours to correct this paper.

2.mom told me not to play soccer in the street，she wanted me to go to school early.

3.he has already picked up his suitcase. but this suitcase is too big to carry.

4.my grandma was ill yesterday，father wanted me to visit her tomorrow afternoon.

但是用的句式不一样，那么两者句式都要掌握。如果你是初学者第一个句子于第二个句子意思上是一样的
