【答案】Good morning，ladies and gentlemen.I'm Li Hua.It's my great honor to stand here on behalf of all the students，and share with you my point of view on using cellphone wisely.Using cellphone has increasingly become an important means for people to acquire knowledge and solve problems.But using cellphone for teenagers has its advantages and disadvantages.
First of all，as a wise cellphone user，we can make full use of the most extensive educational resources to broaden the horizon.Besides，we can take the initiative in our study by ourselves without time and space limit.Of course，these disadvantages are as follows.Faced with all kinds of information on the internet，we can't tell the difference between the true and the false，which may be harmful to our study and life.On the other hand，using cellphone itself has some imperfections，making it difficult for us not to be affected.
In conclusion，we should have a good understanding of its advantages and disadvantages and find a proper way to use cellphone more efficiently.That's all I want to say about this point.Thank you!
