回复 梦·风过无痕：Perhaps he sensed that the abilities that seemed to come naturally to so many others didn't come naturally to him ._____ the entire team runs ,only the top seven runners could be accepted.是这样吗?如果是的话我认为这段话的意思是（加上although之后）：大概他感到他没有别人与生俱来的能力吧.尽管整个队伍都在跑（给点背景……我直译了）,只有跑的最快的前七个才会被接受（录用）.although后面用一般式是因为在阐述事实（或者规则?求背景呀亲……）.before肯定是不能替换although了,表示的意思不一样,更何况although还有转折的意思,所以就更不行了.
再问： 嗯，谢谢。能不能讲下although的用法呢？是不是也像if一样“主将从现”？
再问： 1.是不是只要是一般事实，就用一般式？ 2.although有没有特殊用法？
