问题补充：
We don’t need a lot of friends they are good.
A. as many as
B. as much as
C. as long as
D. as more as
答案：
A. as many as
B. as much as
(答案→)C. as long as
D. as more as
解析：句意：我们不需要很多朋友，只要他们对我们友善就行。as many as意为“和什么一样多”，修饰可数名词，as much as 意为“和什么一样多”，修饰不可数名词，as long as意为“和什么一样长”或“只要”，as ... as中间多用原级，不用比较级。故选C。
