Question

as的确很复杂啊！花了3小时还是弄不懂！

as ..as可以引导定语从句，前一个as什么意思
【she can marry as healthy a man as she can find（第一个as什么意思，要死adv，同样地，就好假啊）
【the boy has as much progress as we had expected. 前一个as）
【As many children as came were given some cakes. (后一个as 作主语，前一个匪夷所思！视乎是等于while？？)
【He is as diligent a man as ever lived. (as 作主语，百度文库里的什么的主语？)
【I give him as much as he could eat（.第三句我有【一些】把握，因为as第一个绝对是副词，所以much是副词不是代词，所以i give him much,as he could eat.这里的as就是连词而不是关系代词了）
【e've got food for as many people as want it（两个as好难理解，分别什么意思，能翻译句子吗）
【She will marry as healthy a man as she can find . 她将嫁给她能找到的任何一个有钱人。（主句中出现the same, as, such, so修饰先行词，需选择as做关系代词在定语从句中做主语或宾语。
那么一个as什么意思啊，不适形容词吗》》？

Answer 1

1. as...as引导定语从句时，第一个as还是程度副词，意思就是“同样，相同”。
第二个as为定语从句的关系代词，类似于which/that/who等，代指其前面的名词/代词，并在定语从句中充当主语、宾语、表语等。
所以楼主发现as在定语从句中充当主语，那是经常出现的情况，不足为奇。

比如：As many children as came were given some cakes.
第二个as，代替先行词children，在后面的定语从句中充当主语。
再如：He is as diligent a man as ever lived.
同样，第二个as代指前面的先行词a man，做ever lived的主语。

2. I give him as much as he could eat.
也通常理解为定语从句，much为代词，相当于much food.
第二个as代替much (food)，在定语从句中充当eat的宾语。

3. We've got food for as many people as want it.
翻译：我们弄到了无论多少人吃都够了的食物。
第一个as还是“一样地”，第二个as代指people，做want it的主语。

4. She will marry as healthy a man as she can find.
还是引导定语从句。
第一个as依旧是程度副词“一样地”（用法上类似于so），修饰形容词healthy，表示程度。
