More than a century ago, the composer and bandleader John Philip Sousa warned that technology would destroy music, who said, “These talking machines are going to ruin the artistic development of music in this country. When I was a boy … in front of every house in the summer evenings you would find young people together singing the songs of the day or the old songs. Today you hear these terrible machines going night and day. We will not have a vocal cord (声带) left.”

Music has greatly changed in the past hundred years, which has been everywhere in our world: rivers of digital melody flow on the Internet or on disc; MP3 players with forty thousand songs can be put in a back pocket or a purse. Yet, for most of us, music is no longer something we do ourselves, or even watch other people do in front of us. It has become a radically virtual medium, an art without a face.

Ever since Edison invented the phonograph cylinder(留声机), people have been assessing what the medium of recording has done for and to the art of music. Sousa was a spokesman for the party of doom; in the opposite corner are the utopians(乌托邦), who argue that technology has not imprisoned music but liberated it. Before Edison came along, Beethoven’s symphonies could be heard only in select concert halls. Now the recordings carry the man from Bonn to the corners of the earth. Glenn Gould, after renouncing live performance in 1964, predicted that within the century the public concert would disappear into the electronic air.

Having discovered much of my favorite music through LPs and CDs, I am not about to join Sousa’s party. Modern urban environments are often so soulless or ugly that I’m grateful for the humanizing touch of electronic sound. But neither can I accept Gould’s slashing futurism. I want to be aware of technology’s effects, positive and negative. Fortunately, scholars and critics have been methodically exploring this terrain for many decades, trying to figure out exactly what happens when we listen to music with no musicians in the room.

Why do we laugh and get amusement from so many different things，from puns (双关语) to pratfalls? Why are some things funny to some people and not to others? How is that while a successful joke can cause pleasure，a sick one can cause serious harm?

Over the centuries，various scholars have attempted to produce a universally agreed-upon theory of humor．Plato and Aristotle introduced the superiority(优越感) theory，the idea that people laugh at the misfortune of others．Their theory seems to explain teasing，but it doesn’t work well for knock-knock jokes．Sigmund Freud argued for his relief theory，the concept that humor is a way for people to release psychological tension and reveal their inner fears and desires．His theory works well for dirty jokes，less well for most puns．

The majority of humor expels today agree with the incongruity theory，the idea that humor arises when there’s a gap between what people expect to happen and what actually happens．Incongruity has a lot going for it — jokes with unexpected funny lines，for example，fit well．But scientists have found that in comedy，unexpectedness is overvalued．

With the goal of developing a new，more satisfactory explanation，I produced “the gentle violation(违背)theory”，the idea that humor arises when something seems wrong or threatening，but is actually OK or safe．A dirty joke，for example，trades on moral or social violations，but it’s only going to get a laugh if the person listening is open enough to consider the subject OK to talk about．Similarly，puns can be seen as linguistic violations that still make grammatical sense．

And while most humor theories have struggled to account for tickling (挠痒痒)，or just avoided the phenomenon altogether，my theory accounts for even this kind of laughter．Tickling involves violating someone’s physical space in a gentle way．People can’t tickle themselves — because it isn’t a violation．

1.What is the author’s attitude towards Plato and Aristotle’s theory?

A．Critical．B．ApprovingC．uncaringD．Unclear

2.According to Sigmund Freud’s theory，we can infer that __________ .

A．people will laugh when they see others suffer

B．telling dirty jokes is a relief of one’s nervous feelings ’

C．unexpectedness can explain how humor works

D．tickling doesn’t involve psychological tension

3.According to the author，why are some things funny to some people but not to others?

A．Because the sense of humor varies greatly from person to person．

B．Because people have different expectations for the same thing．

C．Because some people lack the sense of safety deep in their heart．

D．Because people’s understanding of violation is different．

4.What is the author’s main purpose of writing this passage?

A．To draw people’s attention to the research of humor．

B．To criticize people’s misconceptions about humor．

C．To explain what exactly causes people to laugh．

D．To prove the sense of humor can be developed．

-- Has he apologized for his rudeness?

-- __________ .

A．No doubtB．No luckC．Not yetD．Not exactly

Most people know precious gemstones (宝石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It’s more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone’s origin.

Beneath the surface of a gemstone, on the tiny level of atoms and molecules, lie clues to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.

Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.

To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles called electrons separate from atoms.

The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.

In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.

Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.
