什么因素不使含盐量下降呢?这要求我们留意文中对含盐量高低变化起作用的因素的细节描述。文中第二段末句总结了影响含盐量的因素:蒸发(evaporation)使含盐量增加,降水(rainfall)和河水流入(runoff)使含盐量降低,后文中提到海冰的形成和融化也影响含盐量。因此,该题很明显应选B项。 |
(2) |
文中提到Weddell海是在叙述了第三种改变含盐量的过程之后,这一种改变主要与冰的形成与融化有关。海水结成冰后含盐量升高,冰融化后含盐量又变低。随后,文中以Weddell海为例,说明海水结冰后,冰冷的海水含盐量增高。所以,该题应该选A项。 |
(3) |
B项表示“海水结冰的结果是使水的含盐量下降了”。而文中却提到海水结冰后,冰下的水含盐量增高。因此B项不是事实。 |
(4) |
此文主要围绕海水的含盐量进行叙述,列举了三种不同情况下含盐量的增减。因此最合适的答案为C项。而A项“水分的去除或减少”,B项“水由液态转为固态”和D项“降水对海水含盐量的影响”,都只是文中叙述的一个方面,而不是主要观点。 |
