The pie chart illustrates the proportions/percentages of reasons why students use mobile phones at a certain university. Specifically, the percentage for doing academic study accounts for 59.5%, which is the highest percentage among the options. The proportion for killing time and scanning information accounts for 20.5% and 17%, respectively while “other” is a mere 2%. There are two fundamental factors involved in this phenomenon. First, undergraduates are facing fierce competition in modern society. Only if they do their utmost to study to get good points and learn/grab necessary skills, can they obtain a decent job after graduating. Thus, most students would rather use their mobile phones to do academic work and scan information than kill time. (Scanning information is less than killing time) Second, mobile phones have become the main way to relax and get information nowadays. When students get tired from studying, they like to use them for leisure. From my perspective, mobile phones have already played an essential role in university life. However,It seems like a double-edge sword. Students should remind themselves do not be addicted to their phones, especially, by staying far away from computer games and social media.
