我们每个人都应该懂得感恩,学会感恩.请以I should thank----（我应该感谢---）写一篇短文 急用呢

I should thank my parents 。They have raised me up while they rarely ask for pay back。I should thank my friends who acompanied with me when I was upset。I should also thank those people who cast their whole lives in the construction of our nation while I even not know their names。Thank all o them with my best wishes。
