同学你好哦~
1. ...  I work at home I have a flexible schedule.【英文中because的使用要有发生因果关系的逻辑，这里工作11小时和后面这句没有因果关系，直接去掉because】

2.Working at home has both advantages and disadvantages. 这里advantages和disadvantages是复数，后面是单数？需要尽量一致

3.when I finish my work I can do anything what I want to and the disadvantage is that I have a lot of work to do，even Sunday and Saturday.【want后面要加介词，have sth to do有...要做】

4.If I plan to take my son to the beach on Sunday，but something comes up at my work，and  I have to finish my work at first.【at first表示首先，at the first后面常加time表示第一次】

5.... but that is how life is可以直接说but that is life
祝同学学习愉快~
