Air-conditioner is a kind of machine used at home, at the office or in the shopping hall and any other places.It is designed to change the air temperature and humidity within an area.Air-conditioner is used for cooling and sometimes heating depending on the air properties at a given time to create more favourable conditions.It's frequently used during in the hot summer.In the north of China, it's used for heating in the cold winter.I like air-conditioner in the summer days and nights.Once it turns on, the cool air will spread all over the room and I don't want to leave there anymore.But people often feel dry in the air-conditioning area.Therefore, remember to drink more water to prevent you from too dry.
空调是一种供居家，办公，商场以及其他场所使用的电器。它是用来改变某一区域内的空气温度和湿度的。空调是用来降温或升温的，它是根据特定时间的空气性质来创造更适合的条件的。空调在炎热的夏天使用频率最高。在中国的北方，空调在寒冷的冬天用来升温。夏天我喜欢日夜吹空调。只要一打开它，凉快的空气就会散布整个房间，我就再也不想离开房间了。但是有的人在有空调的地方会觉得皮肤干燥。因此，记得要多喝水以防干燥。
