“BANG!”the door caused a reverberation(回声).It was just standing there,with father standing on one side,and I was on the other side.We were both in great anger.“Never set foot in this house again!”stormed father.I rushed out of the flat and ran along the street.The street lights were shining,causing rather a sad feeling.

A young father who held a child in his arms walked past me.I felt as if I saw my childhood from another space:happy and carefree.But now…I don’t know whether it is because I have grown up or because dad is getting old.We differ in our ways of thinking.He always put his opinions and codes(习俗)of behavior on me.Whenever I do something wrong,he never admits(接纳)it.We are just like two people coming from two different worlds.1 wandered(徘徊)in the streets,until I had only the street lights to keep me company.When I finally reached the high-rise apartment block in which I lived,I saw that the light was still on.

I thought to myself:“Is father waiting for me.or is he still angry with me?”

All the lights were off except father's.Dad was alwys like this.Maybe he didn't know how to express himself.After an argument he has the habit of creeping up(悄悄地来到)in my sleep.This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature.With the key in hand,1 was as nervous as I had ever been.At last,I decided to open the door.As soon as I opened the door tears ran down my cheeks.I suddenly realized that the iron(铁的)door that I had imagined between us did not exist at all.Love-it's second to none.

A.Perhaps the father is getting older and older.

B.Perhaps the son has already grown up.

阅读下列材料:

材料一:新朝代首先遇到的第一个大问题是帝国跨地过广,不能全部由中央集体管制,于是采取了一种“斑马式”的省级组织。有些地区秦朝所设郡县原封不动地任其存在,其他地区则派遣新任命的王侯,世守为业。……这样的安排纯系一时权宜之计,从未预计长久保持。即使在创业人刘邦去世之前,已有不少侯国,因有心和无心的差错,被削被除。……这种加强中央统治的政策,至第五个皇帝刘彻在位期间达到极点。

——黄仁宇《中国大历史》

材料二: 本朝鉴五代藩镇之弊,遂尽夺藩镇之权,兵也收了,财也收了,赏罚行政一切收了,州郡遂日就困弱。……靖康之役,虏骑所过,莫不溃散。 

——朱熹《朱子语类》
