get up to talk 看了你追问中的前后文才比较好翻译,有时后光几个字无法判断.
一楼的有诚意也很努力但功力还有待加强：
before the class 在此的意思是 在全班同学面前
got up to talk before the class 自然就是 “站在全班同学面前说话” 这样的描述
nine months out of the year 意思就是一年中的九个月,不存在“过不过完”的概念,比如：
His parents live in Beijing nine months out of (a / the) year,the rest of the time they travel all over the world.
Seattle is a rainy city,it usually rains nine months out of the year.
look through travel magazines 是 翻阅旅游杂志 （但隐含了试图从中寻找某种资讯）的意思
