---->(During all the time that I study in The US high school, history class is always a big challenge for me. Because my English ability was not good enough, most of the time I just can not understand what is the teacher said, there are a lot of new words and teacher’s speak speed are too fast for me. Also, although I am really hard study at home to understand all the notes, I still cannot get a good grade in the test, cause I cannot understand question--- people can not improve language ability in a short time. It was makes me feel frustrated in a long time, Before 2019, I just think I cannot do anything good to my history study, and I almost want to give up. However, I am not a negative person that just let failure defeat me. One day, I have a idea in my mind: why I don’t try to study harder and to change the way to study? In that time, I feel a strong energy to pushed me do this idea. There is two days to next quiz, I study six hours per day and change my way to study that I find lot of example questions online to review over and over again makes me understand as much as possible. Finally, during that quiz I got a good grade. This things teach me that when you face to challenge how important people persevere. )
