B

    An old man was going home late one night with his horse and cart after a day's hard work. When he was not far away from his house, the light on the cart went out. He tried but could not repair it. He was near his home, and so he went along the road without a light. When a policeman saw this, he stopped the old man.

    "Where is your light?" asked the policeman. "No man may take a cart along the road at night without a light. You know that. You have broken the law." "I had a light, but it has just gone out," said the old man.

    "I don't believe that story. What's your name and where do you live?" asked the policeman. "Please don't write down my name," said the old man. "My home is just there. You can see it from here. I had a light nearly the whole way."

    "You came all the way without a light. What's your name?"

    The old man quickly took the policeman's hand and put it down on the top of the light. The light was still hot and burnt the policeman's hand. The policeman jumped and he was very angry. "Now, what do you think?" said the old man. "Did I come all the way without a light?"

阅读下面两则文言文，完成小题。

     【甲】至若春和景明，波澜不惊，上下天光，一碧万顷；沙鸥翔集，锦鳞游泳；岸芷汀兰，郁郁青青。而或长烟一空，皓月千里，浮光跃金，静影沉璧，渔歌互答，此乐何极！登斯楼也，则有心旷神怡，宠辱偕忘，把酒临风，其喜洋洋者矣。

       嗟夫！予尝求古仁人之心，或异二者之为，何哉？不以物喜，不以己悲；居庙堂之高则忧其民；处江湖之远则忧其君。是进亦忧，退亦忧。然则何时而乐耶？其必曰“先天下之忧而忧，后天下之乐而乐”乎。噫！微斯人，吾谁与归？（选自《岳阳楼记》）

     【乙】若夫日出而林霏开，云归而岩穴暝，晦明变化者，山间之朝暮也。野芳发而幽香，佳木秀而繁阴，风霜高洁，水落而石出者，山间之四时也。朝而往，暮而归，四时之景不同，而乐亦无穷也。

       已而夕阳在山，人影散乱，太守归而宾客从也。树林阴翳，鸣声上下，游人去而禽鸟乐也。然而禽鸟知山林之乐，而不知人之乐；人知从太守游而乐，而不知太守之乐其乐也。醉能同其乐，醒能述以文者，太守也。太守谓谁？庐陵欧阳修也。
