  My name is Tony.I have a twin brother. Well, my twin brother is called

Daniel, and he is four minutes younger than me. We were both born on the 5th of

January, and I think that we look alike very much. Daniel is a little taller than me

and he has very dark hair, but we have the same eyes and nose and smile.We

weren't always in the same classes at school because my parents wanted us to be

a bit more different.We used to be dressed the same way, but different in color,

me in red and him in blue, and we used to have a birthday cake that was always

half was red and half was blue, but I guess we are quite different.He’s really,

really active, and just very different from me. At school I was always in the top

classes getting A's and he was always failing the exams. He did a lot of sports

but I didn’t, so people say we are very different.

阅读下面文段,根据要求答题。(15分)

包弟在我们家待了七年,同我们一家人处得很好。它不咬人,见到陌生人,在大门口吠一阵,我们一声叫唤,它就跑开了。夜晚篱笆外面人行道上常常有人走过,它听见某种声音就会朝着篱笆又跑又叫,叫声的确有点刺耳,但它也只是叫几声就安静了。它在院子里和草地上的时候多些,有时我们在客厅里接待客人或者同老朋友聊天,它会进来作几个揖,讨糖果吃,引起客人发笑。(选自《小狗包弟》)

请学习《小狗包弟》描写一种动物。要求运用拟人手法,通过具体场景,写出它的习性和性情。不少于200字。
