急需一篇英语读后感作文！！!

I have read a book named Harry Potty,the famous novel around the world.The writer created a wonderful and magical world,which is loved by all children in the world.
What I gained from the book is that you should have a good heart and not be afried of any difficulties.To be a brave and good person,halping the one who is in trouble.
Not only the people but the details in that book give me a deep depression.I hope that if you have a chance to read it,you will like me,loving it.
