under construction
The phrase "或是" (huò shì) is used in Chinese to present alternatives or choices, similar to "either... or..." in English. It connects two or more options, indicating that one of the options is true or applicable.
For example, in the sentence "这件事或是哥哥做的，或是弟弟做的" (This matter was either done by my older brother or my younger brother), "或是" introduces two possible subjects responsible for the action.
Similarly, in "你或是参加这次考试，或是明年再学一遍这门课" (You can either take this exam or study this course again next year), it presents two choices regarding the action the listener can take.
The structure typically follows the pattern: "或是 + option 1，或是 + option 2". This construction is useful for expressing uncertainty or offering choices in conversation.
