The human body demands that the amount of salt in the blood always stay the same.When the body does not get enough salt, it protects itself by letting less salt leave the body in urine and sweat. But it cannot reduce this output to zero. Some salt is always escaping. On a completely saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys (肾) and sweat glands (腺). It then tries to ad-just to this loss by speeding up its secretion (分泌) of water. In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and, finally, death. The person dies of thirst. In cases where there is little or no water to drink, the body tries to do the opposite thing. Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant. Some African people once drank animal urine______.

However, there are many words with the same denotative meanings but different connotative meanings. For instance, “bat” is an evil animal in European folk legends. The English idioms like “as blind as a bat” and “as crazy as a bat” give explanation by themselves. But many Chinese people believe that “bat” is the symbol of good luck, health and happiness. This is mainly because in “蝙蝠” “蝠” is pronounced the same with “福” (good fortune) in “幸福” (happiness) and “洪福” (limitless blessing). Still, there are many other words whose denotative and connotative meanings are both different in English and Chinese. For example, in the western world, “dragon” is a fire-spitting mythical animal, signifying violence, as in “He is a bit of dragon here.” By contrast, most Chinese people regard “龙” (Long) as a symbol of dignity and power, as in the idiom “望子成龙” (hold high hopes for one’s child). 1.
