问题：英语选择题______heis,heseldomshowshis 
______ he is,he seldom shows his precus coins to others.A.Coin-collector as B.As a coin-collectorC.A coin-collector asD.Coin-collestor that
回答：选择A, n + as + sb is = Although sb is a n.
例如该题Coin-collector as he is = Although he is a coin-collector
这个结构需要注意两点:
1. 这是as的让步转折结构,因此暗含"虽然...但是"这个意思在里面,通常用来表示一种吃惊;因此这句话可以翻译成,他是个硬币收藏家,可他很少.....
2. 这个结构里的名词若是单数,前面不加a,所以C是错误的.
