Be Grateful to Life 感恩生活
Once President Roosevelt’s house was broken into and lots of things were stolen. Hearing this，one of Roosevelt‘s friends wrote to him and advised him not to take it to his heart so much. President Roosevelt wrote back immediately，saying：“Dear friend，thank you for your letter to comfort me. I’m all right now. I think I should thank God. This because of the following three reasons：firstly，the thief only stole things from me but did not hurt me at all；secondly，the thief has stolen some of my things instead of all my things；thirdly，most luckily for me，it was the man rather than me who become a thief...”
It was quiet unlucky for anyone to be stolen from. However， President Roosevelt had such three reasons to be so grateful. This story tells us how we can learn to be grateful in our life.
Being grateful is an important philosophy of life and a great wisdom. It is impossible for anyone to be lucky and successful all the time so long as he lives in the world. We should learn how to face failure ormisfortune bravely and generously and to try to deal with it. If so，should we complain about our life and become frustrated and disappointed ever since then or should we be grateful for our life and rise again ourselves after a fall？ William Thackeray，a famous British writer，said：“Life is a mirror. When you smile in front of it，it will also smile and so will it when you cry to it.”If you are grateful to life，it will bring you shining sunlight. If you always complain about everything，you may own nothing in the end. When we are successful，we can surely have many reasons for being grateful，but we have only one excuse to show ungratefulness if we fail.
I think we should even be grateful to life whenever we are unsuccessful or unlucky. Only by doing this can we find our weakness and shortcomings when we fail. We can also get relief and warmth when we are unlucky. This can help us find our courage to overcome the difficulties we may face，and receive great impetus to move on. We should treat our frustration and misfortune in our life in the other way just as President Roosevelt did. We should be grateful all the time and keep having a healthy attitude to our life forever keep having perfect characters and enterprising spirit. Being grateful is not only a kind of comfort，not an escape from life and nor thinking of winning in spirit like Ah Q. Being grateful is a way to sing for our life which comes just from our love and hope.
When we put a small piece of alum into muddy water，we can see the alum can soon make the water clean. if each of us has an attitude of being grateful，we‘ll be able to get rid of impulse，upset，dissatisfaction and misfortune. Being grateful can bring us a better and more beautiful life.
如果我们每个人都有感恩的态度，我们就能摒弃冲动、沮丧、贪念和不幸。感恩可以使我们的生活变得更加美好。

有一次，罗斯福总统的家遭到洗劫，丢失了大量的物品。他的一位朋友听闻此事就写信给他，并劝他不要过多地把这件事放在心上。罗斯福总统立刻给他回信，他写道：“亲爱的朋友，谢谢你写信来安慰我。我现在很好。我想我应该感谢上帝。有以下三点原因可以解释：首先，贼只偷了一些东西但却丝毫没有伤害我；其次，贼只偷了部分而不是我的全部财物；再次，对我来说最幸运的是，是他成为了小偷而并非是我……”
对任何人来说，家里被盗都是不幸的。但是，罗斯福总统却用了这样三个理由来感恩。这个故事告诉我们，在生活中我们应该学会感恩。
感恩是一项重要的生活哲学，也是生活的伟大智慧。只要活在世上，任何人都不可能永远幸运和成功。我们应该学会勇敢地、豁达地面对失败和不幸，并要想办法解决。倘若我们遇到了困难，自那一刻开始，我们是该抱怨生活、沮丧气馁、丧失信心，还是应该对我们的生活满怀感恩之心、跌倒后再爬起来呢？英国著名作家威廉·萨克雷说过：“生活是一面镜子，如果你在它跟前笑，它也会对你笑；如果你对着它哭，它也会对着你哭。”如果你对生活充满感恩之心，它就会给你带来明媚的阳光。如果你总是事事抱怨，你最终将一无所有。当我们成功时，我们一定会有很多感恩的理由，但是一旦失败了，只需要一个借口就可以表现出忘恩负义。
我认为每当遭遇失败和不幸的时候，我们都应该感恩生活。只有这样，在失败的时候我们才能发现自身的弱点和缺陷；在不幸的时候我们同样也能获得慰藉和温暖。这样就可以帮助我们鼓起勇气克服遇到的困难，并获得更大的冲力继续前进。我们应该效仿罗斯福总统，换种方式处理生活中的挫折和不幸。我们应该一直感恩，永远对我们的生活抱有健康客观的态度，拥有完美的人格和进取精神。感恩不是一种安慰，也不是对生活的逃避，更不是阿Q式的精神胜利。感恩是用我们的爱和希望歌颂生活。
我们把一小片明矾放入污水中，可以看到它能够使污浊的水变清澈。如果我们每个人都有感恩的态度，我们就能摒弃冲动、沮丧、贪念和不幸。感恩可以使我们的生活变得更加美好。
