    Every fast-food employee knows that the drive-through window is the worst position. The window sticks with constant ice; the roar of engines hurts your 1; your words are lost in the howling wind.

    On a 2 afternoon, everything changed.   

    Every once in a while, the sub-zero temperatures seal a 3 windows shut. Drivers don't exactly enjoy having to stand outside in the cold, 4 their orders into a speaker box, when they expect to drive through on their heated leather seats. In such cases, most customers tend to show their annoyance to the employees.

    This woman was 5.

     “I'll get the next car's 6 a s well,” she said as she came up to the window to pay. She stood outside, 7 much snow on her hair. Though she was obviously freezing, her bright 8 lit up her face like a fire.

     “You can't 9 their drinks,” I said, confused and tired.

     “No, but I'll buy them,” she said. “Pay it forward and all that.”

    Completely puzzled, I charged her as 10, and when the next customer arrived at the window I explained what had just happened. I watched as his 11 changed — first angry to be out in the cold, then 12 at the random act of kindness, and finally, delighted by his 13.

     “I suppose I'll pay for the next order then,” he replied, nodding and waving at the impatient driver 14 him. He 15 over the cash and received his pre-paid hot drink.

    The trend continued. Customers arrived annoyed, only to leave 16 and pleased. Some were shocked to spend much more than they had expected, 17 others ended up receiving their order for less than half the price.

    Five vehicles passed, then ten, then twenty. No one refused to pay. Customers stood at my window 18 a fist-full of change to buy drinks for a complete stranger. Cars drove off, honking (鸣笛) and 19 their thanks.

    It only takes one customer, one person, to change the entire 20 of traffic. It only takes one moment, one smile, to warm up even the coldest of days.

材料：说地理大发现是资本主义性质的运动，主要是就其发展趋势或结果而言的。我们还应该说，它是一场资本主义和封建主义的联合扩张，或双重扩张。关于荣誉的追求是否属于地理大发现的三大追求（上帝、荣誉和黄金）之一的问题，需要谨慎对待。当我们讨论荣誉之类的问题时，千万不能忘记：主观的追求不是地理大发现的根本原因，那背后的客观条件或客观可能性才是根本性的。

《明史·杨巍传》记载：“明制，六部分莅天下事，内阁不得侵。至严嵩，始阴挠部权，迨张居正时，部权尽归内阁，逡巡请事如属吏，祖制由此变。”这一变化表明明代内阁（    ）
