A possible version
As is shown in the first drawing, it is windy and rainy outside, and yet the flower in the greenhouse is at its best. In the second drawing, however, things are quite different. When exposed to the outside, the flower appears weak and fails to stand against the bad weather.
Based on the above drawings, we can see that one can hardly challenge possible difficulties if he stays in a comfortable surrounding too long a time. Similarly, with living standards improving, people tend to provide their children with material comfort and as a result, children are often spoiled. They may possibly succeed with the protection of the comfort. But what if they leave the so-called comfort? They’ll probably be destroyed by the tough reality as what happens to the flower.
It is obvious that the education of the young is vital to the nation. Don’t let them grow up in the greenhouse all the time. If exposed to the outside surroundings, they’ll be stronger and better prepared for their future.
