下列说法正确的是： Which options may be correct？（there are more than one correct answers）

A、如果函数f(n)是O(g(n))，g(n)是O(h(n))，那么f(n)是O(h(n))【 if f(n) is O(g(n))，g(n) is O(h(n))，then f(n) is O(h(n))】

B、如果函数f(n)是O(g(n))，g(n)是O(h(n))，那么f(n)+g(n)是O(h(n))【if f(n) is O(g(n))，g(n) is O(h(n))，so f(n)+g(n) is O(h(n))】

C、如果a＞b＞1, 下列说法正确的是： Which options may be correct？（there are 是，但不一定是【if a＞b＞1,is，may not be】

D、函数f(n)是O(g(n))，当常数a足够大时，一定有函数g(n)是O(af(n))【if f(n)是O(g(n))，When constant a is big enough ，there must be g(n) is O(af(n))】
