The Internet has been found a new usage. Increasingly, more and more Americans are having a(an) {#blank#}1{#/blank#}to become their own doctors, by going online to order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店). Some people{#blank#}2{#/blank#} doctors because of the high cost medical care, especially if they{#blank#}3{#/blank#} health insurance. Or they may{#blank#}4{#/blank#} to see a doctor because they find it embarrassing to discuss their weight, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of {#blank#}5{#/blank#}in the past. But to become their own doctors can be{#blank#}6{#/blank#}.

    Every day, more than six million American search the Internet for medical answers. Most of them have no{#blank#}7{#/blank#} about what they find. In 2002, a survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. Actually, most of such web sites are only interested in doing{#blank#}8{#/blank#} business. Of the 169 websites the researchers rated, only 16 scored as "high quality". Recent studies found faulty facts about all sorts of other disorders, causing one research team to {#blank#}9{#/blank#} that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.

    The problem is that most people don't know the safe way to surf the web. "They use a search engine like Google, get 18 trillion choices and start clicking. But that's risky, because almost anybody can put up a site that looks {#blank#}10{#/blank#} , so it's hard to know National Cancer Institute.

    The elementary means of communicating with other people is conveying messages by voice. This fact is widely acknowledged and we recognize the voice as a(n) {#blank#}1{#/blank#} characterizing the identity of a person. The array of voices is immeasurable as no two are exactly similar. They can be nasal, resonant or shrill produced in accordance with the individual physical {#blank#}2{#/blank#} of the throat.

    One possible implementation of the {#blank#}3{#/blank#} of voice recognition is voice profiling used by police analysts as a method of substantiating court evidence in trials. Every year, thousands of audiotapes with recorded interviews or {#blank#}4{#/blank#} utterances are put to the purpose to help identify the probable {#blank#}5{#/blank#}. Specialists dealing with the voice investigation claim that people can give themselves away by their {#blank#}6{#/blank#}, inflections or other voice attributes like pitch, intensity and loudness. A recorded sample is usually {#blank#}7{#/blank#} into electric impulses and later transformed into a pictorial recoding which is processed by a computer program. Very frequently voice analyst have a stake at deciphering the relevant information which may be {#blank#}8{#/blank#} with background noise or other interfering sounds until they attain the {#blank#}9{#/blank#} results.

    Thankfully, these efforts help the police detect individuals who threaten their victims by phone or inform about bomb {#blank#}10{#/blank#} or those who make offensive calls disturbing the peach of decent citizens.

    Frederick Douglass was an escaped slave in the movement that fought to end slavery in the United States. He became a{#blank#}1{#/blank#} voice in the year before the Civil War.

D.C. The two-story house, which contains many of Douglass's personal possessions, had undergone a three-year {#blank#}4{#/blank#} . (Thanks to the NTS website, however, you don't have to live in the nation's capital to visit it. Take a tour online.)

He was born in Frederick Augustus Washington Bailey to a slave mother and a white father who never knew Douglass grew up to become the first black {#blank#}5{#/blank#} to hold a government office— as US minister and consul general (总领事)to Haiti.

    As a youth, he never went to school. Educating slaves was illegal in the South, so he{#blank#}6{#/blank#}  taught himself to read and write. At 21 years old, he escaped from his slave owner to Massachusetts and changed his last name to Douglass, to hide his identity.

    In the 1850s, Douglass was involved with the Underground Railroad, the system {#blank#}7{#/blank#} up by antislavery groups to bring runaway slaves to the North and Canada. His home in Rochester, N.Y. was near the Canadian border. It became an important station on the {#blank#}8{#/blank#} , housing as many as 11 runaway slaves at a time.

New York and New Tax

According to a Manhattan Institute survey, more than half of high-earning New Yorkers are working entirely from home and 44% are considering leaving the city. Ned Lamont, Connecticut's governor, has said "the old idea of the commuter(通勤者) going into New York City five days a week may be outdated." It does seem {#blank#}1{#/blank#} that the tens of thousands commuting from Mr. Lamont's state will continue to do so. The region's governors have {#blank#}2{#/blank#}well together to deal with the pandemic(流行病), but the friendliness may soon end over taxes.

When people from {#blank#}3{#/blank#}states like New Jersey and Connecticut commute to New York to work for a New York-based employer, they must pay New York tax on the related earned income. Even those who work from home must pay New York taxes unless the employee is working outside New York by {#blank#}4{#/blank#}.

Taxpayers and those states are looking closely at this loophole(漏洞). In December, Connecticut and New Jersey applied to the Supreme Court to consider a case which {#blank#}5{#/blank#}a state's authority to tax non-residents' income while they are working remotely. They think this is definitely a(n) {#blank#}6{#/blank#} to the city's finances. "Firms have considered leaving the city before, and employees are gradually accepting the idea. They have been working remotely for almost ten months and they've {#blank#}7{#/blank#}to that idea."

Companies are also watching the progression of the billionaire Mark to Market Tax Act, which would treat capital {#blank#}8{#/blank#}from billionaires' property as taxable income. New York's Democratic governor said he would reject any laws {#blank#}9{#/blank#}heavy taxes on the rich, because it would drive out wealthy, mobile residents. It would not take too many moving trucks for the city to feel the economic loss, says Michael Hendrix. A 5% {#blank#}10{#/blank#}of New Yorkers making about $10,000 would result in an annual loss of $933m—roughly the amount distributed to the city's health department.
