请大家帮我看看这篇英语文章有没有什么语法错误?
Today is National Day.We have no classes.In the morning,I went to the People's Square with my parents.We had a good time.In the afternoon,I went to Pudong New District to visit my grandmother.On my way home,the roads were very crowded .But the continuous vehicles actually are such systematic .I thought that is because everybody is very coordinates the police .At evening,I helped my parents to cook supper.I had a busy day today.

I thought that is because everybody is very coordinates the police 应该是I thought that was because everybody was ……
还有at evening应该是in the evening
如果要用at的话应该是at night的.
