1、Gun Rights in the US
Immediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president and the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.
Strictly speaking, the US is not the only country here gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seem unwilling and politically incapable of doing anything serious to stop it.
In countries like Britain and Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) and the electoral (选举) system.
The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both, they prefer power.
According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don't want to give up their arms they keep to protect themselves.
Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professor in the Virginia incident had been carrying a legal weapon, they might have been able to stop all this. "In his opinion, the massacre (大屠杀) is an argument for more people to carry weapons, not fewer.
Americans' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK's Guardian newspaper.
One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American's responsibility to have a gun.
"Each person," he said, "should not rely solely ____ the government for protection."

3、What Is the Coolest Gas in the Universe?
What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.
We encounter an interesting situation when we discuss temperatures in _____ Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.
The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.
Why is the two scientists' work so important to science?
In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein's calculations helped him theorize would behave as Bose thought but only at very cold temperatures.
Scientists have also discovered that ultra-cold atoms can help them make the world's atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.

4、An Early Form of Jazz Music
Music comes in many forms; most countries have a style of their own. At the turn of the last century, when jazz was born, America had no prominent music 0f its own. No one knows exactly when was invented or by whom. But it began to be heard in the early 1890s. Jazz is America's contribution to popular music. In contrast to classical music, which follows formal European traditions, jazz is spontaneous and free in form. It bubbles with energy, expressing the moods, interests, and emotions of the people. In the 1920s' jazz sounded like America. And so it does today. The ____ 0f the music are as interesting as the music itself. American Negroes, or blacks, as they are called today, were the jazz pioneers. They were brought to the Southern states as slaves. They were sold to plantation owners and forced to work long hours. When a Negro died, his friends and relatives formed a procession to carry to body to the cemetery. In New Orleans, a band often accompanied the body . On the way to the cemetery the band played slow, solemn music, suited to the occasion. Furthermore 0n the way home the mood changed. Spirits lifted. Death had removed one of their numbers, but the living were glad to be alive . The band played happy music, improvising on both the harmony and the melody of the tunes played at the funeral. This music made everyone want to dance. It was an early form ofjazz.
