I remember that I like paper because of another people.He like paper,so I like paper.If I will remember him all the life?I don't konw.

1.Today is Thursday,it's January 31th,it's raining and wouding.不能用“，”并列简单句，要用连词。改为Today is January 31th,Thursday,and it's raining and winding all day.你有一处拼写错误。
2.I am very unhappy because of those former things . 没交代清什么是those former things .
3.Since than,I will work harder in my English,and I hope I will be first place in English like math and physice.
Since than是从那以后的意思，意义不对，改为From now on“从现在起”
4.I hope I will be first place in English like math and physice.少介词on,改为I hope I will be on the first place
单词拼写错误，physice改为physics.
5.I remember that I like paper because of another people.根据下文 another people改为a person.
6.He like paper,so I like paper.主语为he,谓语改为likes.
7.If I will remember him all the life?I don't konw.
改为Wheather I can remember him all the life?I don't konw.
总之，错误不少且全为简单句，句式欠丰富。
