英语翻译
This is particularly important in a meeting where complex arguments need to be put forward and where it is vital to get the best out of the situation and those present in as little time as possible.
get the best out of sth 有这个短语吗?the situation 又指什么?更费解的是后一句的those 指什么?
你们的意思是the situation and those present是连一块的？可是，如果是这样的话in不就很多余吗？
没有in as little time as possible这种说法吧？而且这句话是出自BEC中级 真题辑（二）TEST3 中的改错题——删掉句子中多余的词。修改后的结果就是上面那句话，in不是多余的。所以我觉得present in 是连一块的。但是又弄不明白those指什么。
