请翻译：我们不能在世界上独立生存

We cannot live/survive alone in this world.

We cannot survive in the world alone.
个人认为survive更适合 生存

We can't live all by ourselves in this world.

We can not survive in the world, independent

We can't live in the world individually~~ 呵呵个人观点，意思是，我们不能独立的在世界生存~

we can't in the world individually
