B Just now, I entered the website “Topic for Today”, I feel   3 6 (interest) in the report on middle school students’ using cell-phones on campus．In fact, many students now come to school 3 7   cell-phones．My schoolmates have different opinions．Some think 3 8   is convenient to get in touch with others with the cell-phone, which also makes you feel safe especially in time of trouble． 3 9   , it is nice to enjoy various functions of different cell-phones． 40   think differently．First, the cell-phone is not 41   must in school, as 42   are some IC phones in the school 43   (make) it easy to call others．Second, many students often play e-games and send e-messages with their cell-phones, even in class, 44   will surely have bad effects on their study．What’s more, it will result in a great waste of time and money．In my opinion, the cell-phone is a 4 5   (use) tool in our daily life．But it doesn’t mean we can use it freely in school．
