Complete silence is found only in laboratories called anechoic(无回声)rooms．The walls and ceilings, made of blocks of special sound-sucking materials, are more than three feet thick, while floor coverings are six-foot layers of feathers or cotton wool．Silence here can be as painful to the ears as the din(continuous loud noise)of a steelworks or a rocket blast-off, yet scientists get used to this and stay in these silent rooms for hours at a time, using microphones and electronic equipment to test the various materials being developed to make the world a less noisy place．
Architects have used scientific discoveries to solve noise problem in a number of ways．Walls are hollowed(having empty space inside)and then filled with sound-sucking materials similar to cotton wool．Extra-thick carpets(毯子)cover the floors, and thick woolen curtains cover the windows．Air conditioning and heating channels are made less noisy by having the air passing through hundreds of tiny holes in baffles(屏蔽)made of sheets of soundsucking materials．
Unfortunately, these techniques and others often work too well in some buildings．Noise-proof rooms become almost anechoic and people living in them are disturbed by the lack of sound．One way of handling this problem is to use what they call “sound perfume”－artificial(similarly produced, made by man)noise is piped to rooms through small loudspeakers．

BELIEVE it or not, the color of the tie Barack Obama wore to the inauguration(就职典礼)is now a hotly debated topic．The level of public interest in Obama’s tie might seem strange but many people believe his choice will symbolize the type of government he plans to run, as the color of a politician’s tie is thought to convey ideas of power, trustworthiness and more．
Polities of ties．
It may be the least practical item of male dress, but it is arguably the most expressive．In the UK and many other coun－tries around the world, conservative(保守的)politicians may wear a blue tie and their liberal opponents a red one．In America, the colors go the other way round．The Republicans have in recent years become associated with the color red, and the Democrats with blue．But in spite of this, bush wears blue ties more often than any other color．
What they mean
According to Sharon Haver, editor of focusonstyle．com, in America the feelings associated with colors overrule their political significance．“a guy who want to be regarded as strong and in charge would wear red,” Haver says．Unsurprisingly, the business tycoon Donald Trump is known for wearing red ties．But what about blue? According to Haver, “Blue is a softer color… Look at the sky．It’s peaceful and calm and trustworthy．”
Selecting the right tie for the right occasion．
●Perfect job interview tie．
Perhaps no other tie －wearing occasion is as important as the job interview．Gilchrist, the fashion expert, advises playing it safe and choosing a conservative one．Best choices are solids, stripes or small patterns．An excellent color is burgundy(深红色)or another serious color．Avoid pink or yellow, which suggests that the wearer lacks gravity．
Pattern ties, Gilchrist suggests, should be limited to a maximum of three colors．A striped tie is a safe choice as this is acceptable to everyone．Last, Gilchrist recommends saving the expensive “hip” tie for those applying for glamorous creative jobs．
●Date－night tie
When picking out the right tie for taking a girl out on a date, spend more time considering color than pattern．According to studies, women are attracted to men wearing the color blue, because blue gives the image of a “stable, faithful, constant, always there” person．So what is the worst color to wear on a date? “Flattened caterpillar(毛虫)yellow－green,” according to Gilchrist, “it will repel both sexes equally．”
(1)
Why are people interested in the tie that Obama wore to the inauguration?
[ ]
A．
Because they think the tie he wore will enable them to know about his personalities and policies．
B．
Because they want to advise him how to select an appropriate tie for such a big occasion．
C．
Because they think the tie will tell if he is trustworthy as they expected when he assumes office．
D．
Because they believe the tie is an essential part of dressing to a mature politician like Obama．
(2)
What can we infer about Bush, the former president, from the passage?
[ ]
A．
He was probably liberal in his policies when he was in power．
B．
He was a Republican when he served as president．
C．
He wore only blue ties and had no ties of alternative colors．
D．
He wanted to make himself unique by the tie that he wore．
(3)
The example of “the business tycoon Donald Trump” is given to _________．
[ ]
A．
prove that color reflects people’s feelings to a certain degree
B．
show that Donald is so wealthy that he can afford expensive ties
C．
tell that Donald is physically strong and can handle everything
D．
explain that red is a popular color, especially with businessmen
(4)
Which of the following statements is TRUE according to the text?
[ ]
A．
Ties can be ignored by politicians since they are the least practical item of male dress．
B．
Do choose ties carefully before dating, because it is the most important occasion．
C．
Why to avoid pink or yellow ties in job interviews is that they don’t match the atmosphere．
D．
The more colorful the tie is, the more likely you’ll get the job you want．

Careercast．com is out with its list of best and worst jobs of 2012．It's bad news for the writer of this story, but much brighter for the folks who program the code that keeps this website busy．
Using a method that looked at physical demands, work environment, income, stress and hiring outlook, career Website Careercast．com, ranked the top 200 jobs．They also ranked the jobs with the most stress．Not surprisingly, none of the most stressful jobs show up on the best jobs list．
At the top is software engineer and at the bottom is the lumberjack．Cutting trees failed to skate above the bottom 10 percent in all ranking categories, except income．“Unemployment for lumberjacks is very high, and the demand for their services is expected to continue to fall through 2016．And while working outside all day may seem like a great job perk(有额外津贴的工作), being a lumberjack not only is considered the worst job, but also one of the world's most dangerous,” according to Careercast．com．And, for that most dangerous job, a lumberjack earns a little more than ＄32,000 a year．That's about ＄56,000 less than the easy job of a software engineer, which has the average salary at ＄88,000 a year, according to Careercast．
Here's a complete look at the best and worst jobs．And, take a look at the most stressful jobs．You may be surprised．
Best Jobs Worst Jobs Most Stressful Jobs
