请帮忙看看有木有语法错误!
My Favorite Pet
Everyone has their favorite pets,and they want to keep them very much.I am ,too.And my favorite pet is dog,I like it very much.Although buying them are not cheap,and keeping them are not easy.But usually they are good for us.When you are tired,they can make you feel happy.When you are boring,they can make you life get interesting.And they can keep out the thief into the house.Those are so good.So I like dog very much.

Answer 1

Everyone has their favorite pets,and everyone have the desire to keep their pets,as do I.(这里得用do,而不是am.并且,直接用they 和them看不出来到底指的是everyone 还是pets)
My my favorite pets are dogs (句子不能用and 或者but开头),I like them very much(这里狗得用复数),.
Although it's not cheap to buy them,and the upkeep is not easy,I feel that dogs are good for us.(这里是一句话,不是两句话,因为although开头的话,是经典的"虽然...我仍然...”句型.并且,buying them are not cheap不通)
They are good for me because when I am tired,seeing them makes me happy.When I am bored,playing with them keeps my life interesting.(以“你累了,他们..."并不能说明跟前面话题的关系,所以要解释为什么说这句话.并且因为这是你最喜欢的宠物,要以你自己为主语,而不是其它任何人.并且,这里用bored,不是boring)
Besides from keeping me happy,dogs can also keep the thieves from getting into the house.(不能用and 开头,还有要和上文衔接.语法上也有点小小的错误)
Dogs have many good traits,which is why they are my favorite pets.
