I do really be thoughtful by the above pictures,as these vivid cartoon depicted a popularized phenomenon concerning today's children.A beautiful flower seems very well on account of the flower is hiding inside the protect of greenhouse.No winding,no rainy.It grows booming.In the first picture dipicted above contents.However,the second picture,without the protect of greenhouse,the flower was shrucking.
Just as today's children,they are health and happy because their parents solved all the difficult things which their children faced.But these parents didn't find children couldn't accept or solve all of the disordered stiuation by themselves.
Parents should not show their best love to children and also should not do everthing for their children.No difficults,no grow!

只改一篇,太困了去睡觉了.别用太多定语从句,显得罗嗦和生硬,还容易出错.英语要尽量摆脱中式英语.
