快速答案
hora 表示钟表时间；vez 表示次数、场合或轮次。
可靠的方法是先判断这个词在句子里的功能，再翻译。
每个词的作用
hora
hour or clock time
Use hora for time on the clock or a period measured in hours.
vez
time, occasion, or turn
Use vez for one occurrence or someone’s turn in a sequence.
如何选择
- hora: Choose hora if the sentence points to time on the clock or a period measured in hours.
- vez: Choose vez if the sentence points to one occurrence or someone’s turn in a sequence.
例句
Que horas são?
What time is it?
Agora é a minha vez.
Now it is my turn.
常见误区
English “time” hides the difference: uma hora is one hour, while uma vez is once or one occasion.
放到语境中练习
从你的真实生活中选一个句子，写两遍：一次用 hora，一次用 vez。如果两个版本都可以，说明意思怎样变化。
