主要找语法错误

I'm really happy to receive your letter.
In addition to study,I do exercise with my father every morning.Because my PE is so bad.
1.because 前应改为逗号；
2.exercise 应改为复数
3.整句话有些中国式英语,是否作如下的调整：
I do exercises with my father every morning besides studying,because my PE is very poor.或者：My PE is so bad that I have to do exercises with my father every morning besides studying.
Also I read some books including 《Jane Eyre》、《水浒传》、《泰戈尔诗集》,listen to music,watch movies.Sometimes I helped mum cook dinner.
1.in addition 用在此处取代also更加地道；
2.including 最好用such as列举后面的小说,而且还用逗号隔开；
3.英语中没有顿号,改为逗号；
4.I helped要用一般现在时.
About my grade,the No.72 among all the eighth grade students in our school.In Yantai,junior high school don't have gifted classes.
1.句子不完整,缺少谓语动词,改为I am the 72nd of all of the students in Grade 8 of our school
2.About my grade改为as for my position in a name list in the competition
Only senior high school have gifted classes.
Anyway,thank you for giving me advice about physics.
After reading the a review article about Harry Potter movie from New York Time,I think it is a little difficult to read.Because it have some new words.And I have a poor vocabulary.
1.犯了和第一句话一样的错误,后面的because从句前改为逗号；
2.the a review article冠词重复,因为是特指,去掉 a；
3.New York Times 纽约时报
4.Harry Potter movie改为the movie Harry Potter,Harry Potter用作movie的同位语；
5.it have some new words改为it has (或there are) some new words.
Here is my own opinion.
I think full of magic life is really good.应该说a life full of magic,形容词短语作后置定语.
But the Harry Potter movie（改为the story of the movie Harry Potter）isn't as good as（添加that of用以呼应the story of ）the book.(添加therefore,以承接上文) I （also累赘,去掉） read the book again.I found some interesting things in the book that the movie didn't show.I told you I am （am改为was,主句是过去时,宾语从句也需要与之一致）disappointed about watching （watching改为seeing,看电影习惯用see a movie） Harry Potter 6.But I really hope the Harry Potter 7 can be better.And when I knew that the Harry Potter 7 will split into two movies that will hit (movie与hit是动宾关系,所以从句中要用被动语态will be hit) in late 2010 and summer 2011,
I think it will make me wait to long so that I will forget what it tells me.
1.改成so long that …it will make me wait so long that …
2.that从句改为完成时：I will forget what it has told me.
But I like to wait.I also hope it could be better than Harry Potter 6.
August 1st is the Army Day,
(also) grandpa and grandma have been married for 50 years.
上面这句话很别扭,与前面的Army Day承接不紧密,可以改为非限制性定语从句,修改如下：
on which Grandpa and grandma got married 50 years ago,and we had celebrating party at Lijiaoqiao Hotel
(此句去掉We ate dinner at the Lijiaoqiao Hotel,需要指出的是专有名词前不可再用the).Grandpa and grandma were really happy.We talked lots of old things.The next day,my father and I saw （改为visited或called on） my grandpa,grandpa Liu and Grandpa Wang‘s exhibition.
后面的半句不明白要表述什么意思,不过名词所有格用法不对,
如果同姓一家人,可以说grandpa and Grandpa Wang’s exhibition；如果不同姓,则应该说grandpa Liu’s and Grandpa Wang‘s exhibition.
