看你要形容什么了。如果你要形容人很多的话，就是busy，eg：1. 苏州有条禁令， 不准在这条热闹的街上停车。Suzhou has a ban on parking cars in this busy street. 2. 是的。 一年的这个时候故宫总是非常热闹。Yes, it can be very busy at this time of year. 如果你要形容气氛，lively。eg：1. As you might imagine, this is a very lively group. 正如你所能想象的，这是个非常活跃的团队。2. Liquor was a kind of liquid food to him and made his mind lively. 酒对他而言是一种液体的食物并且可以使他的思维活泼。
