Today, I was blamed by my boss again.... but i don't think she is reasonable

First, I was a green hand in trade line and I want to do something related with foreign trade but they just make me do things with domestic trade so I have no stage  to  give play to my english ability.  There are a lot,lot numbers for me to remember: cost of every purchaser and applier with each different products and different transportation fees. Sometimes even the senior collegues don't know the number ethier...I just begin this job about one month so when the boss askeed me the number in random, I answered her another number.Actually what she asked was not taught to me ......Then i was blamed .....It is not the first time i was blamed.

I don't like the  depressed atmosphere here and fake, hypocritical interrelationship here. They want to imitate the boss' style no matter it is right or wrong. They show their admiring in front of the boss but turn to be another attitude behind her.....I know I am not same with them and I don't want to change. I don't want to live for life but want to live for what i like and want. I don't know this is perseverence or  stubborness....So how do U guys make this change when U were in my state??
