The ground water can be divided into "soft water" and "hard water". Soft water has few impurities or none at all while hard water contains some more dissolved minerals. In general, hard water is drinkable, but it may have a slight taste because of various minerals.
One place where hard water can be found is a ground underlying a base of limestone and shale. Rainwater dissolves materials as it comes down and this results in water’s taste and hardness.
We can sometimes find ground water that is almost as soft as rainwater under a bare sandy area. These clays hard water from the underground is popular among the citizens of this country. They believe that mineral water is good for health, but some hard water has the dissolved minerals that are harmful to our body.
Scientists suggest that all the ground water should be specially treated before, it is sold.
选项
A、Soft water contains more dissolved minerals.
B、Hard water contains more dissolved minerals.
C、Hard water is not drinkable.
D、Soft water is easier to drink.
答案
B
解析
事实细节题。软水和硬水的主要区别在于"Soft water has few impurities... while hard water contains some more dissolved minerals.”故B正确。A将软水和硬水的水质特点弄混了;文章说到,一般来说,硬水是可以饮用的,所以选项C不正确;而无论软水还是硬水,都要经过特殊的处理后才能饮用,因此排除D。
