Present Perfect называется

I want to explain my position: I don't think that phones in class can make us less concentrate and I have some examples to prove that. First of all, you need to have some useful materials that not always in touch, like internet-resources or online quizzes. On the other hand, we can distract more often on our messages without even understanding this. But, in my humble opinion, phone allows me to always be on the wave, if I haven't understand something by teacher's words, I can search it and find the right explain. Obviously, our phones make us to be more lazy, because we can find all answers here. To sum up, I said 2 pros and cons and the final point of me will be the following: phones - are generation C best friends, and it makes us defenseless against the world, we can't predict our relation and go deeper in that tech-sphere. But, in conclusion, phones are our air, our connection link to that world, we study by online system and always must be prepared for the emergency situation. So, I think, that phones should be in class.
