for questions 1 and 2,你只要记住当你形容一个物品(subject)的quality 和 quantity的时候,你要把形容它quality或quantity的单词放在物品的前面:
copies -> 你的subject, as many -> 它的quantity
parcels ->你的subject, as heavy ->它的quality
列如: you are as pretty as the flower. the flower -> subject, as pretty as -> quality
3, 前面说了It, 所以success是singular, 那就不能用much了.
4, are 不应该在里面
5, Paper tiger is not as fierce as it is painted.
