"but"和"otherwise"都是英语中用来表示转折关系的连词。它们的用法和意义略有不同,具体如下:
1. "but"表示转折、对比、否定、限制等关系,常用于将两个相对的信息对比并联系起来,表达一种不同于前面所说的相反或者排除的意思。例如:
- I like spicy food, but my friend prefers bland food.
- She is smart but lazy.
- I have plenty of time, but I should start working on this project.
2. "otherwise"表示否则,常用于表示一种不同于前面情况的结果。它通常和"if"一起使用,表示“如果不这样,就会发生另外一种情况”。例如:
- You need to finish your work by 5 o'clock, otherwise you won't be able to go home.
- Please turn off your phone during the movie, otherwise it will disturb others.
- We need to catch a taxi, otherwise we will be late for the appointment.
总之,"but"用来表达相反、对比、限制等意思,而"otherwise"则用于表示一种不同于前面情况的结果。
