　　4.What's the difference between swimming in the pool and swimming in the sea?

　　It's gonna be very different, cuz scientifically speaking , sea water has a higher density than the fresh water in the pool which effects our buoyancy, we will float better because of the higher density in the sea. And what’s more, there is current in the sea, obviously it is harder to swim against the current or waves at least.

　　有很大的不同，因为科学地说，海水比游泳池的淡水密度更大，影响我们的浮力，由于海水的高密度，我们可以更好地浮着。另外，海里有海浪，很显然，至少逆着海浪游泳更困难。
