[阅读材料]

There is a real joke.When some guys were talking heatedly about “F4”in the living room, the father came in and interrupted: “Which is more powerful, F-4 or F-16?” The boys burst into laughter.Obviously, the father took F4 for a type of fighter plane.He didn’t know that F4 is a pop group extremely popular among young people these two years.

Then what does the “F” in  F4 stand for? Fever or fortune? It is certainly not “failure” for sure! We look at the success and appeal of these 4 stars from the popular drama Meteor Garden 《流星花园》,who took the island by storm during their brief visit here.For sure, they look good.Each of them being 1.80 meters tall, they are all very popular throughout the world.

But what exactly is the appeal of these 4 young guys? Nobody can tell.Maybe some of young students are just following the fashion.Then why is Meteor Garden stopped from being shown on TV in China? Well, some young people just could not agree.In fact, students are not too young to tell black from white.And they must be clear that every coin has two sides.While they find interest in F4, they must be clear what bad that drama will do us.
