The phrase "come up" has several meanings depending on the context. For example, in a conversation, you might say, "Something came up, so I had to cancel our meeting," which means an unexpected event occurred. If someone mentions an idea during a discussion, you can say, "That topic came up during the meeting." It can also refer to something rising, like "The sun came up at six this morning," or someone approaching physically, as in "He came up to me and asked for directions." In exams or interviews, people often say, "I hope that question doesn't come up," meaning they hope it won’t appear. So, whether it’s about something happening, appearing, rising, or being mentioned, “come up” is pretty versatile in everyday English!

「come up」是一個常見的英語片語，最基本的概念是某件事即將發生、被提到，或突然出現，所以它可以根據情境有不同含義。例如：在聊天時，朋友可能說 “I have to go—something has come up.”，這表示突然有緊急的事情發生；又或者老師提醒學生 “The mid-term exam is coming up next week.”，意思是考試快要到了；還有在會議中，有人可能說 “Your idea came up during the discussion.”，表示你的點子被提到了。用法上，come up 後面常接時間、事件或原因，語氣自然、口語感十足，記得不要加受詞時態錯誤就可以輕鬆使用！

The word attend is a verb that means to go to or be present at an event, like a meeting, class, or concert—for example, “I plan to attend the conference tomorrow.” Someone who attends an event is called an attendee, which is a noun—so you might say, “There were over 300 attendees at the workshop.” Finally, attendance is also a noun, but it refers to the act of being present or the number of people present—for instance, “Attendance was low due to the bad weather.” So basically, you attend something, an attendee is the person who attends, and attendance is the overall presence or headcount.

「attend」這個動詞最常見的意思就是「參加、出席」或「照顧」。口語中我們常說 I will attend the meeting tomorrow.，表示「我明天要出席會議」；若是講到照顧，可以說 She attends to her grandmother every weekend.。使用時記得 attend 後面若是接活動（meeting, class, party 等）通常不需要介系詞，不要說 attend to the meeting；但若是 attend to 表示「處理、照料」，就一定要加 to。
