Summary：
           This week, I read chapter 4 for this book. This chapter's title is "Mom, Did You Vote?". In 1917, women wanted to vote. They thought American soldiers are fighting for democracy in Europe, and they also should fight for it at home. However, like many men, The president Woodrow Wilson thought that most other issues are more important. Well, some women marched in front of the White House with big banner. They wanted to vote. Finally, in 1920, American women went to the polls.
