等了24小时英文怎么说

在英语中，"等了24小时"可以用"waited for 24 hours"来表示。这个短语的来源是由两个单词组成的：

"wait"：这个动词的意思是等待，等候，常用于表示等待某件事情发生或某个人出现。例如：
I waited for the bus for half an hour. (我等公交车等了半小时。)
She waited for him at the airport for three hours. (她在机场等他三个小时。)
"for"：这个介词的意思是表示时间的持续长度。例如：
I will be away for a week. (我将离开一周。)
He has been sick for three days. (他已经病了三天。)

结合以上两个单词，就可以得到"waited for 24 hours"这个短语，意思是等了24小时。下面是一些英文例句及其中文翻译：

I waited for the bus for 24 hours, but it never came. (我等公交车24小时，但它从未来过。)
She waited for him at the airport for 24 hours, but he never showed up. (她在机场等他24小时，但他从未出现。)
