The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere (大气层) with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero .Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of comet(彗星).When the fragments(碎片)landed in the southern part of the giant planet, the explosions were watched by scientist here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the earth’s atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The waves moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the earth, but the north won’t escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.

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 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．
1.During money production, we must consider all EXCEPT that it must .
A．last a long time
B．be hard to copy
C．be interesting to look at
D．be done by the president's order
2.We can learn from the passage that the security threads .
A．are narrow pieces of plastic
B．are pressed outside the bills
C．are longer than the width of the bills
D．are actually made of cotton and linen
3.How many presidents are printed on the American money?
A． Four B． Five C． Six D． Seven
4.Why are the two-dollar bills not made often?
A．Because no one wants them．
B．Because their material is a bit more expensive．
C．Because they aren't used in America any more．
D．Because they aren't damaged quickly like other bills．
