From my point of view,I am in for that no matter what you do-Never,never give up .Perhaps you unfortunately failed,you would not regret cause you had done your best,and at least you had tried,you had opptunity of success.If you just give it up,that means you abandon the chance of success.

You must kown Edison ,the guy who invented the light bulbs and brought the whole world the light.In spite of his talent as a great scientist,he didn’t succed immediately.In fact,he had tried thousands of materials to find an appropriate one.In other words,as a genius as Edison,he had failed for thousands times before he succeed.He had said that a genius is made of 1%talent and 99%diligence.So what made Edison a famous scientist was not only his innate talent but also his spirit of never giving up and keeping working for his goal.Let’s suppose that Edision didn’t insisit on working ,probably we are still using oillight today.

I also had this kind of experience.In China,a 800-meters-running exam is included in the entrance exam for junior students getting into seniors.For us girls,the 800 meters seems endless.And to run 800 meters within 3minutes is too afflicted to bear.We should circle the playground for 4 times.The first ring,was always simple and full of energetic.And the second ringwas often still tolerable.Nonetheless,when it came to the third ring,I felt unable to breath,and strong pain in my legs,it was hard to lift my legs like it was filled with lead.My heart beated fast as if it would jump out my chest.I almost feel unconscious of things around..I only knew that lots of my classmates had given up.But I couldn’t,if I did.The first two circles would be in vain.Since I had carried on to this step,I was getting closer and closer to the final line.I told myself that I must go on running,I could do it as long as I didn't give up.Eventually,I passed the final line within the demanding time.I succeeded as I knew.

From the up two instances,you can see that most time,the power of spirit can take equal or more vital role in our life.Please remember,whatever difficulty is in your life,face it and keeping trying,you can succeed unless ou give up.Never stop working for your goal,one day,your goal will finally achieve.

I will take TOFEL within 20 days,please help me correct the essay and give me some advices,thanks a lot.
