1. Let me give you an example, just like your desk is full of books, but you do not learn by yourself, knowledge is still not in your mind, you must pay enough attention to it, active learning, to achieve the goal. 2. Swimming, as long as you get into the pool, you can swim a few times, you can learn to swim, is a relatively simple thing. 3. The competition is not an easy thing, you have to spend a lot of energy to get good results.

“你当比赛是游泳啊, 扔进去自己学” 你当(这项）比赛（须要做的事能自己学会吗？就象）是（学习）游泳（一样）啊, （别人把你）扔进（游泳池）去（你）自己（就能）学（会游泳），（把你拉到比赛场你就会比赛）。 这句子是口语，它省略了很多常识内容。

Doing competition is not as easy as you think that it couldn't be learnt naturally just like we learn to swim.

You treat competition like swimming, throw yourself into it to learn.
