如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。 导致海洋的盐度变化的基本过程有三个。

其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。这样由于盐留了下来，所以盐度增大。

当然，如果这种方式走向极端，将会余下白色的盐晶体。 与蒸发相反的是降水，如降雨，由此水被加入海中，海水被稀释，从而盐度降低。 这种情形会发生在大量降雨的地区，或江河入海岸处。 因此，盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。

一般来说，在阳光很强烈的`热带地区，海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。 同理，在江河稀释海水的海岸地带，海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。 海水冻结时，溶于其中的物质被留了下来。 这样，在新形成的海水冰面的正下方的海水比在冰形成之前有更高的盐度。 当然，当冰融化的时候，会降低周围水中的盐度。 在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。 这些大密度的海水下沉，可以在世界海洋的深水域发现。

Campus love

Nowadays, campus love is popular. Some college teachers argue that students should give up love for the sake of learning. They maintain that love is time consuming and influences one's learning. Some students, however, hold that a student who falls in love will study harder and will make greater progress. They don't believe that a person in love lags behind in his studies. Please write an essay of no less than 150 words and talk about your views on campus love.
