Researchers from Zogby International did a study for the American Speech-Langusge-Hearing Association. It involved 300 high school students and 1,000 adults. They were asked about their use of portable music devices. Some of the most popular are Apple Computer's iPud, C.D. players and portable laptop computers. 40 percent of students and adults said they set the sound levels, or volume, at high on their iPods. But students were two times more likely to play the music at a very loud volume. More than half of the students said they would probably not limit their listening time. And about a third said they were not likely to reduce the volume.
The study found that more than half of the students and less than 40 percent of the adults had at least one kind of hearing loss. Heating experts say part of the problem is the listening equipment people are using. They say large earphones that cover the whole ear are probably safer than the smaller earplugs that come with most music players. Earplugs are thought to be less effective than earphones in blocking out foreign noises.
Hearing loss may not be apparent for years. But once it happens, it is permanent. About 30 million Americans have some hearing loss. One third of them lost their heating as a result of loud noises.
How can listening equipment cause hearing loss in people？

A．People may use portable laptop computers to listen to music.
B．People may set them at high volume when they listen to music.
C．People may listen to music while walking on the street.
D．People may use large earphone when they listen to music.
The sensation of sound involves a variety of factors in addition to its speak level. Advertisers are skillful at creating the impression of loudness through their expert use of such factors. One major contributor to the perceived loudness of commercials is that much less variation in sound level occurs during a commercial. In regular programming the intensity of sound varies over a large range. However, sound levels in commercials tend to stay at or near peak levels.
Other "tricks of the trade" are also used. Because low-frequency sounds can mask higher frequency sounds, advertisers filter out any noises that may drown out the primary message. In addition, the human voice has more auditory (听觉的) impact in the middle frequency ranges. Advertisers electronically vary voice sounds so that they stay within such a frequency band. Another approach is to write the script. so that lots of consonants (辅音) are used, because people are more aware of consonants that vowel (元音) sounds. Finally, advertisers try to begin commercials with sounds that are highly different from those of the programming with which the commercial is buried. Because people become adapted to the type of sounds coming from programming, a dramatic change in sound quality draws viewer attention. For example, notice how many commercials begin with a cheerful song of some type.
The attention-getting property of commercials can be seen by observing one-to-two-year-old children who happen to be playing around a television set. They may totally ignore the programming. However, when a commercial comes on, their attention is immediately drawn to it because of its dramatic sound quality.
According to the passage, the maximum intensity of sound coming from commercials ______.
A．does not exceed that of programs
B．is greater than that of programs
C．varies over a large range than that of programs,
D．is less that that of programs
A．That they don't always use the TOEFL and the Michigan Test scores correctly.
B．That they look at transcripts instead of scores.
C．That they should insist on a rigid cut-off score.
D．That they are looking for an appropriate alternative.

We can begin to see the importance of color selection. Although red might be perfect for a restaurant，it would be wrong for an art exhibition room，where we want to look at the paintings，not at the walls behind. Because of its effect on size，white could be used to make a small room seem larger，or dark blue to make a large one seem smaller.
Another way that we sometimes speak of colors is to say that they are loud or quiet. Again we are talking about the feeling that colors give us. We use sound to express how much colors catch our attention.
16. If a man wants to make a room warmer，which color will he choose for the walls？
A. Green.
B. Yellow.
C. Black.
D. Brown
