《Harry Potter》读后感
《Harry Potter》is one of the most famous novel in the world.It is a story about a boy named Harry Potter.His parents were gone when he was a baby.So he lived with his uncle and aunt,but they were bad to him.When he was 11 years old he felled he is unordinary.He is a wizard!He went to a school named Hogwarts School of Witchcraft and Wizardry.He knew a very dangerous wizard-Voldemort killed his parents there and the wizard killed a lot of people.Just Harry Potter could kill Voldemort.If he couldn’t,then Voldemort will kill him.Harry had two good friends in Hogwarts.They’re Ron and Hermione .They helped Harry to do lots of difficult thing.A teacher named Dumbledore helped Potter,too.At last Harry potter kill Voldemort and he lived happily.
I think Harry Potter was brave and kind.He is very helpful.I like him.He fought with the dragon and went into the river.It causes me very amazing.Hermione and Ron were brave,too.They did lots of things for Harry.I admire them very much.
Harry and Voldemort was both orphan,but why one is kind and one is bad?I think the answer is “love”.Harry had love from his friend,Sirius Black,Dumbledore and Mrs.Weasley.He is happy.But Voldemort didn’t have.He was alone.He just wanted to be the king of the world.He didn’t see the other thing.For example friendship,help others…… If he feels that he will be real happy.And I think Voldemort was poor.Nobody loves him.His friends hate him or just afraid of him.
