Space is where our future is—trips to the Moon,Mars and beyond. Most people would think that aside from comets (彗星) and stars,there is little else out there. But,since our space journey started we have left so much trash (垃圾) there that scientists are now concerned that if we don't clean it up,we may all be in mortal (致命的) danger.

The first piece of space junk was created in 1964,when the American satellite Vanguard I stopped op?erating and lost its connection with the ground centre. However,since it kept orbiting around the Earth with?out any consequences,scientists became increasingly comfortable abandoning things that no longer served any useful purposes in space.

It is estimated that there are now over 500,000 pieces of manmade trash orbiting around the Earth at the speed of up to 17 ,500 miles per hour. The junk va?ries from tiny pieces of paint chipped off rockets to cameras,huge fuel tanks,and even odd items like the milliondollar tool kit that astronaut Heidemarie Ste-fanyshyn-Piper lost during a spacewalk.

The major problem with the space trash is that it may hit working satellites and damage travelling space?craft. Moreover,pieces of junk may collide (碰撞) with each other and break into pieces which fall back to the Earth. To avoid this,scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

A little old couple walked slowly into McDonald's on one cold winter eve?ning. It seemed that they didn't come to the right place with the young families and young couples eating that night.

The little old man walked right up to the cash register,placed his order with no hesitation and then paid for their meal. The couple took a table near the back wall and started taking food off the tray. There was one hamburger,one order of French fries and one drink. The little old man unwrapped the plain hamburger and carefully cut it in half. He placed one half in front of his wife. Then he carefully counted out the French fries,divided them in two piles and neatly placed one pile in front of his wife. He took a sip of the drink and then set the cup down between them.

As the man began to eat his few bites of hamburger,the crowed began to get restless. You could tell what they were thinking,"That poor old couple. All they can afford is one meal for the two of them."

As the man began to eat his French fries,one young man stood and came over to the old couple's table. He politely offered to buy another meal for the old couple to eat. The old man replied that they were just fine. They were used to sharing everything.

As the little old man finished eating and was wiping his face neatly with a napkin,the young man could stand it no longer. Again he came over to their table and offered to buy some food.

After being politely refused again,he finally asked a question of the little old lady,"Ma'am,why aren't you eating? You said that you share everything. What is it that you are waiting for?"

She answered,"The teeth."
