Chinese Reading Excerpt

人体内部的温度称体温。保持恒定的体温,是保证新陈代谢和生命活动正常进行的必要条件。体温并不是固定不变的,可随性别、年龄、运动和情绪的变化等因素而有所波动,但这种改变经常在正常范围内。

在健康状态时,如饮食正常,衣着适宜,人体的体温一般是比较恒定的,即保持在37℃(大致介于36.2℃~37.2℃),而不因外界环境温度的改变而变化。人体正常体温平均在36~37℃之间(腋窝)。

在正常生理状态下,体温升高时,机体通过减少产热和增加散热来维持体温相对恒定;反之,当体温下降时,则产热增加而散热减少,使体温维持在正常水平。正常体温的标准是根据多数人的数值,并非为个体的绝对数值。

The temperature inside the human body is called body temperature. Maintaining a constant body temperature is necessary in ensuring conditions for normal metabolism and life activities. Body temperature is not fixed and can fluctuate with factors such as gender, age, movement and mood changes, but this change is often within a normal range.

When in a healthy state, such as with normal diet and proper clothing, the body temperature is usually relatively constant, maintaining a 37 ℃ (roughly between 36.2 ℃ ~ 37.2 ℃), and not does not change much even with changes in ambient temperature. Normal body temperature averages between 36 ~ 37 ℃ (armpit).

In normal physiological state, when the body temperature increases, the body reduces heat production and increases heat dissipation to keep the body temperature relatively constant; on the other hand, when the body temperature drops, the heat production is increased and heat dissipation is reduced, so that the body temperature is maintained at normal levels. The normal body temperature standard is based on the measurements of most people, and is not the absolute measurement of each individual.
