　　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 any where 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(令人沮丧的)experience he often had while singing in his church choir(唱诗班). 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 colleague(同行), 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(附着)it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more samples(样品)of his invention so that they could use the new type of notes themselves.

　　Fry and some other people at 3 M 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. 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.

What is colour? Why do some of the things around us look red, some green, others blue?

　Colours are really made by reflected(反射)light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.

　Some of the light is reflected and some is taken in(吸收)and turned into(变成)heat(热能).The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes.

A．see its colour      B．see its heat        C．not see its colour    D．see nothing

What does it mean to say that we live in a world of persuasion? It means that we live among competing interests. Your roommate’s need to study for an exam may take priority（优先）over pizza. Your instructor may have good reasons not to change your grade. And the object of your romantic interest may have other choices.
　　In such a world, persuasion is the art of getting others to give fair and favorable consideration to our point of view. When we persuade, we want to influence how others believe and behave. We may not always prevail— other points of view may be more persuasive, depending on the listener, the situation, and the merits of the case. But when we practice the art of persuasion, we try to ensure that our position receives the attention it deserves.
　　Some people, however, object to the very idea of persuasion. They may regard it as an unwelcome interruption into their lives. Just the opposite, we believe that persuasion is unavoidable — to live is to persuade. Persuasion may be ethical（合乎道义的）or unethical, selfless or selfish, inspiring or degrading. Persuaders may enlighten our minds or catch our vulnerability(弱点). Ethical persuasion, however, calls on sound reasoning and is sensitive to the feelings and needs of listeners. Such persuasion can help us apply the wisdom of the past to the decisions we now must make. Therefore, the most basic part of education is learning to resist the one kind of persuasion and to encourage and practice the other.
　　Beyond its personal importance to us, persuasion is necessary to society. The right to persuade and be persuaded is the bedrock of the American political system, guaranteed by the First Amendment to the Constitution（美国宪法）.
