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.

 

　　空調是一種供居家，辦公，商場以及其他場所使用的電器。它是用來改變某一區域內的空氣溫度和濕度的。空調是用來降溫或升溫的，它是根據特定時間的空氣性質來創造更適合的條件的。空調在炎熱的夏天使用頻率最高。在中國的北方，空調在寒冷的冬天用來升溫。夏天我喜歡日夜吹空調。只要一打開它，涼快的空氣就會散布整個房間，我就再也不想離開房間了。但是有的人在有空調的地方會覺得皮膚干燥。因此，記得要多喝水以防干燥。
