1- Examples that confirm the statement: In the text itself, (it's a good idea to start from the document itself and extract main points) , in real life...

2- and why is it dangerous? :  desire to imitate and impossibility to do so. Teenagers often look for models, and celebrities offer very superficial ones

2- Why? How?  Celebrities benefit from media treatment, papers/tv/the net etc.. so their importance is exagerated compared to " real heroes"

3- But then, what do we mean by " real heroes" ? So give some examples for you ( this is necessarily subjective) : brave people who save lives or " daily life heroes" who manage with daily difficulties? Artists who create beauty? etc...People who set examples because they convey human qualities?

4- Conclusion : Your point of view : for instance ( = for example) It is true that we have come to put more value on celebrities than on real heroes, However if we are trained to think for ourselves, we can make a difference between  them and decide who we really want to be inspired by.
