Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes, the pieces of paper that you can fasten almost anywhere and then remove without leaving any sign that they were there, are an example of such an invention.
Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from a frustrating experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.
Around that time, Fry heard about a new adhesive (粘合剂) that a workmate, Dr. Spence Silver, had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough to not tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.
A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new "bookmarks" and attached it to a report he was going to give to a workmate. Soon, co-workers were asking Fry for more samples of his invention so that they could use the new type of notes themselves.
Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the "sticky pieces of paper" for trial use(试用). When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off. The invention of Post-it Notes showed that Art Fry________.

We are all busy talking about and using the Internet, but how many of us know the history of the Internet? Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time, At first the Internet was only used by the government, but in the early 1970s. universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" the Internet easier. Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among young people. The Internet has now become one of the most important parts of people's life.How long has the Internet been used?

A 5R Rule for Environment
1. Reduce(减少)
If you want to reduce waste, you should use things wisely. A large number of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste.
2. Reuse（再利用）
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle（回收）
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed(打碎) flat and melted(融化) and the metal things are made for new coke cans.
4. Recover （恢复）
When you buy a box of apples, there may be a few rotten apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.
5. Repair（修补）
If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw—away” society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.The “Reduce” rule mainly requires(要求) us ______.
A. to use things wisely
B. to cut down many trees
C. to use less paper The right order of recycling coke cans is ______.
a. collect the used cans b. melt them c. smash them flat d. send them to a factory
A. a b c d B. a d c b C. d b c aThe “Recover” rule mainly requires us ______.
A. to throw waste thing away
B. to cover waste thing with the earth
C. to get back the useful parts ______ is the best way to do with your broken tables.
