上舞蹈课为什么用take

也可用have a class ,但have a class 也有给学生上课的意思，take a class就没有给学生上课的意思。

Let him go take a class or volunteer somewhere. Don\'t take no for an answer.

让他去参加一些课程学习，或者去哪里服役。

Take a class or even get an advanced degree to arm yourself with skills that are more enduring.

参加一门培训课程，或干脆考取更高级的学位，以此来得到更持久的技能来武装自己。

I will definitely regret it if I take a class without any of my friends in it.

如果我选修的课程没有朋友去上，我绝对会后悔的。
