Producing money requires both artistic and technological skills. Dollar bills are made so

Producing money requires both artistic and technological skills. Dollar bills are made so that they are interesting to look at but very hard to copy. In total, there are sixty-five separate steps required to make a dollar bill．
The money making process begins when a yearly order is sent by the Federal Reserve Board. That order will then be divided in half. Half will be done here in Washington, D.C. and the other half will be done in Fort Worth, Texas. Next, the Bureau orders special paper which is actually cloth since it is 75% cotton and 25% linen．
This paper is made so that it can last a long time. And, it is made with details that make it hard to copy. For example, bills contain security threads. These narrow pieces of plastic are inside the paper and run along the width of the bill. This special paper is also made with very small blue and red fibers．
Once the money is printed, guillotine cutters (切纸机) separate the sheets into two notes, then into individual notes．The notes are organized in bricks, each of which contains forty one-hundred-note packages. The bricks then go to one of twelve Federal Reserve Districts, which then give the money to local banks. Ninety-five percent of the bills printed each year are used to replace money that is in circulation, or that has already been removed from circulation．
You may know that America's first president, George Washington, is pictured on the one- dollar bill. But do you know whose face is on the two, five, ten, twenty, fifty and one hundred-dollar bills? They are, in order. President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin．
The average life span of a one-dollar bill is twenty-one months. But a ten-dollar bill lasts only about eighteen months．The one hundred-dollar bill lasts the longest, eighty-nine months．One popular question is about the two-dollar bill. This bill is not printed very often. This is because many Americans believe two-dollar bills are lucky, so they keep them．

(答案→)C 解析：本文叙述了美元生产制作的过程及要求。美元制作时要求既好看，耐用又难以复制，因此用使用独特的材料。并且里面有用塑料制成的防伪线。不同面值的美元上印着不同的重要人物的图像，如美国总统和一些重要的官员。【小题1】 细节理解题。根据第一段的Dollar bills are made so that they are interesting to look at but very hard to copy.和第三段的This paper is made so that it can last a long time.可知美元制作时要求既好看，耐用又难以复制。故选C.【小题2】推理判断题。根据第五段的George Washington, is pictured on the one- dollar bill.They are, in order. President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin．其中Treasury Secretary Alexander Hamilton,和statesman Benjamin Franklin．不是美国总统。因此被印在美元上的总统图像共5位。故选A【小题3】细节理解题。根据第三段的For example, bills contain security threads. These narrow pieces of plastic are inside the paper可知美元中的防伪线是一些窄的塑料片。故选B。【小题4】推理判断题。根据最后一段的.
