11.Just now,I entered the website"Topic for Today".I feel (41)interested(interest) in the report on middle school students'using cell-phones on campus.In fact,more students now come to school with cell-phones.My schoolmates have different opinions.Some think it is(42)convenient(convenience) to get in touch with others with the cell-phone,and it also makes you feel safe(43)especially(especial) in time of trouble.Besides,(44)itis nice to enjoy various functions of different cell-phones.
Others think differently.First,the cell-phone is not a must in school,as there (45)are(be)
some IC phones there,(46)making(make) it easy to call others.Second,many students often play e-games and send e-messages with their cell-phones,even in class,which will surely have bad(47)effects(effect) on their study.What's more,a great deal of time and money will(48)be wasted(waste).In my opinion,the cell-phone is (49)a useful tool in our daily life.(50)But it doesn't mean we can use it freely in school.
