My name is Xiao Fang and I am twenty-three years old ,and graduated two years ago. My major is  business management, I am working in environmental protection company, perhaps you will ask me (or "you are wondering why...") “why are you ready to leave this company”. I will give you an appropriate answer. I think everybody (or every person) has a life goal and wants to live better than other people who your friends or classmates, I am no exception. Every people know neither a free lunch nor free pies ,only ability and more hard work than other people. So I chose to leave to find a new development direction or new working environment ,because the company I am working now cann ’t give me that I want to get.
If I can be working in your company, I will work hard and study hard to get the skillse with the fastest speed for the new job .
Perhaps I am not the most suitable candidate for this job, but I will study hard to prepare myself for this job as soon as possible. thanks

My name is Xiao Fang and I am twenty-three years old. I graduated two years ago with my major in business management and I am working for an environment protection company. Perhaps you will ask me “why are you ready to leave this company,” I will give you an appropriate answer .I think everyone has a life goal and wants to live better than other people such as your friends or classmates, I am no exception. Everyone knows (there's no such thing as a free lunch) only the ability to workharder than other people. I chose to leave to find a new development direction or new working environment because the company I am working with now can’t give me that I want to get.
If I can working for your company I will work hard and study hard to gain new knowledge very quickly. 
Perhaps I am not the most appropriate for this job, but I will study hard and make myself  the right fit for this job. Thank you.

My name is Xiao Fang. I am twenty-three years old ,and have graduated two years ago. My major is in business management  and currently I am working in an environment protection company. perhaps you are thinking to ask me “why are you ready to leave this company” , an appropriate answer is that I think every person has a life goal and wants to live better than other people even your friends or classmates and co-workers, I am no exception .Everyone knows neither a free lunch nor free pies ,only ability and more hard work than another person. So I chose to leave in order to find a new development direction or new working environment ,because the company I am working at now can not provide me the tool or challenges necessary to get what I want to get.
If I can work for your company ,I will work hard and study hard. I will learn quickly and fit  into the new job.  
Perhaps I am not the best appropriate for this job, but I will do what is necessary to make myself perfect for this job
