Fumbling with the buttons to find a good song while driving has been linked to increased risk of crashes, but is listening to music risky? “It depends on the music,” says a report published in the October issue of Accident Analysis & Prevention.

The study found teenage drivers who played their own music had significantly more traffic violations（違規(guī)） compared with background music designed by the researchers to minimize driving distractions, or no music.

Researchers at Ben-Gurion University in Israel recruited(招募) 85 drivers about 18 years old; just over half were male. The subjects were each assigned to drive six challenging road trips that were about 40 minutes long, accompanied by an experienced driving instructor. Music was played on four trips, two with selections from the drivers' playlists, mostly fast-paced vocals, and two with background music, which was a mixture of easy listening, soft rock and light jazz designed to increase driver safety. No music was played on two trips. Subjects rated their mood after each trip and in-car data recorders analyzed driver behavior and errors.

All 85 subjects committed at least three errors in one or more of the six trips; 27 received a warning and 17 required steering or braking by an instructor to prevent an accident. When the music was their own, 98% made errors; without the music, 92% made errors; and while listening to the safe-driving music, 77% made errors. Speeding, following too close, inappropriate lane use, one-handed driving and were the common violations.

The male subjects were more aggressive drivers and made more serious errors than female subjects. The teens played their own music at a very loud volume but significantly decreased the sound level when listening to the safe-driving music, researchers said. Mood ratings were highest on trips with driver-preferred music.

1.What is the key information the author wants to give in Paragraph 1?

A. Many drivers played their favorite music while driving.

B. Drivers shouldn’t search for the buttons to find a good song.

C. Song selection has nothing to do with increased risk of crashes.

D. Listening to certain types of music can increase drivers’ errors.

2.What does the underlined word “ subjects” refer to in this passage?

A. Something being discussed. B. People being written about.

C. People being tested. D. Areas of knowledge or study.

3.In the research, soft rock and light jazz are likely to _______.

A. increase drivers’ safety

B. add to the pleasure of driving

C. change drivers’ idea of safe driving

D. lower drivers’ guard against danger

4.It can be inferred from the passage that in the research ______.

A. the teens committed the most errors

B. the male were more skillful in driving

C. traveling with no music made the least errors

D. driver-preferred music increased the mood ratings

First you need to open an account at “Bux. to”. “Bux. to” is a new international and FREE English based service that allows advertisers to reach thousands of potential customers by displaying their ads on our “Surf Ads” page.

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 (聲帶) 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(留聲機(jī)), 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(烏托邦), 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.

1.The first paragraph is intended to .

A. defend an argument B. make a prediction

C. criticize an attitude D. summarized a viewpoint

2.The author’s attitude towards the recorded music may best be described as .

A. dissatisfied B. defensive C. optimistic D. objective

3.The underlined word “terrain” in the last paragraph most nearly means .

A. region B. subject C. land D. distinction

4.The primary purpose of the passage is to .

A. explain different attitudes of scholars and critics

B. defend the view of one group from the criticism of another

C. advocate an unexpected solution to a pressing problem

D. present the key issues in an ongoing debate
