Take an example of dress shows excessively highlighted by TV channels.
You could say, "For example many dresses are shown" and you could add "which are" between excessively and highlighted.
Similarly, lavish life styles shown in dramas affect many young-ones
You could put "have" in between styles and shown. affect=affected
For instance,week-end
weekend is one word.
society will become even tense
add a "more" in between even and tense.
Hope this helps! :)
