as much as & as many as

2000.11.

32. Female sea turtles, before laying her eggs, swim as much as 2000 kilometers to return to the beaches where they themselves were hatched.

answer is A, why as mush as is correct....

38. Rarely has a technological development had as great an impact on as much aspects of social, economic, and cultural development as the growth of electronics.

answer is B, much-->many

求教 In what condition we could use "as many as " or "as much as "....thanks a lot!!!!

第二题其实考的不是as..as结构，much错是因为后面接的是可数名词复数，应用many修饰。

至于你说的两者区别，我查了一些资料，没有找到，抱歉！等高人指点吧
