About Jewish Life in World War 2 (oral presentation)

I changed book once, and the first book was <Anne Frank>. Actually, the book was not diary that I want to read and boring. But, I am interested in her life, especially Jewish life. So, my oral presentation topic is "Jewish life in World War 2"

During World War 2, Nazis wanted to exterminate Jewish because some unreasonable reasons made them crazy. Because of these unreasonable reasons, a lot of Jewish were killed by seriously terrible method including absorbing toxic gas in a concentration camp or eating poor foods. Sometimes, Jewish forced to go into Ghetto, which was a town where Nazis gathered Jewish. To add the death of Jewish, they could not do anything freely they want. They couldn't go to school, establish their own company, and they should attach patch on their clothes to show they were Jewish so that they had to be segregated by other people. At that time, Jewish lives were not the human being's lives.
