Challenge, this is a frightening but exciting word.

For it, there is Amundsen, a warrior who is still bravely exploring in the ice and snow; For it, there is a pilot who lives in the desert-Saint Exupery. In order to uncover the mystery of nature, human beings have challenged nature with their tiny bodies. When Gagarin became the first astronaut, human beings completely got rid of gravity for the first time. When young China climbers climbed from the northern slope, crossed the Millennium ice and snow, climbed over rocks and planted a bright white five-star red flag on the top of the earth, mankind defeated the highest peak on the earth-Mount Everest. It is the challenge that keeps mankind growing, and it is the challenge that fills life with blood and never back down's courage.

The 20 14 Winter Olympics is in full swing, which is a challenge for mankind. Such a challenge requires higher and stronger faith. When they rushed to the finish line, their sweat brought many shouts, cheers and applause. When they stood on the podium, they successfully challenged themselves! However, there are still many athletes whose names we don't know who are training hard. No reporters interviewed them, no schools talked to them, and no one remembered their faces. But they are still persisting, struggling, striving, and persistence is their label. They are still challenging, and they have not failed.

In the vast universe, there are few human beings, but in this small body, what a huge heart! The challenge spirit of human beings is great enough to shake the universe!

Now the whole world is challenging the future, and so is China. We firmly believe that as long as we also carry forward this fearless spirit, we can win. There is hope for our country. Look at Beijing. How many people are struggling there? They are "drifting north". They are shouldering the burden of their families and are working hard resolutely. They firmly believe that they can use their own hands to support a blue sky for themselves, their families and their children. However, they did not complain, but faced it calmly. Isn't this a more amazing challenge spirit?

Only by constantly challenging can we have a better tomorrow. So life needs challenges!
