我觉得成功靠运气，因为人不能决定在哪儿长大了，不能决定爸妈是谁，也不能决定遇到什么人。

I think that success depends on luck,because people cannot decide where they grow up, cannot decide who their parents are ,cannot decide what people they meet.A student who studies hard will have the choice to go to the best university in the country, but if that student cannot afford the tuition fees, or their family is too poor, then these uncontrollable factors all depend on luck. A poor country could have many clever children but have not received education, so don't have the ability to develop their abilities.

当然拼命学习的学生有选择去全国最佳的大学的机会，但是万一那个学生买付不起学费，、家庭贫穷，呢？而这些不能控制的因素都靠运气。
