Question: Article: Music comes in many forms;most countries have a style of their own. Poland has its folks. Hungary has its czardas. Argentina is famous for the tango. The U.S.A.is known for jazz,the type of music that has gained worldwide popularity. Jazz is an American contribution to popular music. While classical music follows formal European tradition,jazz is rather a free form. It is full of energy,expressing the moods,interests,and emotions of the people. It is breaking and exciting with a modern sound. In the 1920s jazz sounded like America. And so it does today. The origins of the music are as interesting as the music itself. Jazz was invented by American Negroes,or blacks,as they are called today,who were brought to the southern states as slaves. They were sold to farm owners and forced to work long hours in the cotton and tobacco fields. This work was hard and life was short. When a Negro died his friends and s would gather and carry the body to have a ceremony before they buried him. There was always a band with them. On the way to the ceremony the band played slowly,solemn music suitable for the situation. But on the way home the mood changed. Spirits lifted. Everyone was happy. Death had removed one of their members,but the living were glad to be alive. The band played happy music. This music made everyone want to dance. It was an early form of jazz. Music has always been important in Negro life. The black,who were brought to American from West Africa,had a rich musical tradition. In the fields,they made up work songs. Singing made the hard work go faster. And when they got to Christianity,they made lovely spirituals,which have become an everlasting part of American music.
Answer: was started by blacks in America

Answer: From the passage,we can see that jazz _ .

Question: Article: Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space. This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling. This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat. Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling. "We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are _ by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
Answer: result in a warming climate

Answer: .According to the new findings, taking steps to prevent northern forest fires may _ .

Question: Article: When I opened my e-mail the other day,a pretty woman named Rachel appeared on my computer screen.She greeted me by name and started talking with great enthusiasm.Every now and then she stopped to smile at me or blow a kiss.She was reading to me an e-mail from my brother,and a lot of it was about his getting the phone company to give him a highspeed Internet connection.It was pretty cool. Rachel was there thanks to a new technology called Facemail.Facemail lets you send an email that gets ready to the receiver by an attractive male or female form or by a clown .The software,which is free,can be downloaded at www.Facemail.com. Facemail faces are lifelike,and they simulate emotions based on emotions that you put in your text.For example,type in X,and Rachel will blow a kiss. LifeFX,the company that develops the Facemail,is sure there are broad business uses.The reason ebusiness is not popular,the company says,is that buying over the Internet lacks the human touch.But what if you went to the Nike website and Michael Jordan greeted you by name,waited for you and personally closed the sale?And it is talking with Whirlpool about using the technology in a computer screen on a fridge.Then if Mom can't be home when the kids get back from school,she can leave a note with voice and image telling them what there is to eat. Facemail could get hot fast.Personally,I'm a fan.But Facemail should be used with care.The clown looks lively and funny at first.But if you select the clown,put a few rude words in an email and add some angry emotions,you've got a Psychomail .
