Air conditioning is the use of mechanical systems to 【C1】______ that control in such places【C2】______homes, offices, theaters, institutions, factories, airplanes, and automobiles. The most familiar type of air conditioning is summertime cooling. Although important, this is【C3】______one of several aspects of air conditioning. Other applications【C4】______the control of the humidity (or air moisture), cleanliness, circulation of the air, and heating.
Tests have 【C5】______ that people generally feel best 【C6】______ certain temperature, humidity, and air velocity conditions. Temperatures can 【C7】______ from 21.5°C with 70 percent relative humidity to 28 °C with 30 percent relative humidity. Relative humidity is the 【C8】______ of moisture in the air 【C9】______ a specific temperature compared【C10】______the amount it could hold at that temperature.【C11】______air velocities range from 4.5 to 10.5 meters per minute. It is also desirable that an air conditioner【C12】______dust, pollen, smoke, and odors from the air.
In many industrial environments, air conditioning is essential. Most print shops, for example, 【C13】______constant humidity in order to control paper shrinkage and【C14】______the【C15】______operation in some processes.
Libraries, especially ones with rare books, require air control to【C16】______the physical quality of their collections. Bakeries and the tobacco and cotton industries require high humidity【C17】______their products, and perishables such as fruits must be stored in cool, dry rooms. Some electronic components, drugs, and chemicals must be manufactured【C18】______the air is as free as possible【C19】______dust and other particles. Air conditioning is【C20】______in hospitals, especially in operating rooms.
【C7】
选项
A、alter
B、range
C、differ
D、move
答案
B
解析
考查动词辨析。空格处所在句意为:气温可以在21.5℃、相对湿度70%,到28℃、相对湿度30%之间变化。“在…范围内变化”一般用range,故B为正确答案。alter“改变;变更”;differ(常与from连用)表示“不同;不像;相异”,(常与with连用)表示“不同意;意见相左”;move“移动”,均不符合题意。
