Question

Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago.

Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Company. The idea for the product came from an awful 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. Around that time, Fry heard about a new adhesive (粘合剂) that a colleague, Dr. Spence Silver, had created. This adhesive was special because it was strong enough to hold papers together, but not strong enough to tear the paper when it was removed.

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 colleague. Soon, co-workers were asking Fry for more 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 asked 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.

【解析】

试题分析：文章主要介绍了便签纸的发明过程。一些很有用但看似很简单的发明让人们不禁思考很早以前的人怎么就没有想到这样做呢？便签纸是大约二十年前一个叫Art Fry的人发明的。

1.Fry heard about a new adhesive (粘合剂) that a colleague, Dr. Spence Silver, had created. ...it was strong enough to hold papers together, but not strong enough to tear the paper”可知，Dr. Spence发明的粘合剂帮助Fry发明了便签纸，故选C。

2.Fry used pieces of paper as bookmarks to mark the places in his book of songs”和第三段“he wrote a note on one of his new “bookmarks” and attached it to a report”可知，Post-it Notes是一种边缘带有粘合剂的便签，贴在其它物体上时，它不会掉下来，说明便签纸是方便用来记东西的一种便条，故选A。

3.Fry heard about a new adhesive (粘合剂) that a colleague, Dr. Spence Silver, had created”和第三段“Fry realized that his new invention had even more uses than being a great bookmark...Soon, co-workers were asking Fry for more of his invention”可知，在Fry的同事发明了新型的粘合剂之后，Fry才发明了便签纸，之后，这种发明在同事之间很受欢迎，顺序应该是b, d, e，故选D。

4.Some inventions are so useful...that we wonder why no one thought of them long ago.”可知，文章讲的是一些看似简单却非常有用的发明，由此可知，文章应该是刊登在报纸的科技专栏，故选C。
