(Turns out here a)point drivers with passengersare sixty percent more likely to have a car accident that result inhospitalization.
(Turns out here a)point 是什么意思?
The effect(effects) contributeto the 4,000 automobile dust(death)in the U.S. annually, that’s about the sizeof family park.
family(?不确定) park 是什么意思?

有很多语法错误 ...555555555555555555555555:funk:
佩服你的听力水平:loveliness:
还有背景知识:loveliness:

(Turns out here a)point drivers with passengersare sixty percent more likely to have a car accident that result inhospitalization
1.我听到的是turns out yet plain,(是不是插入语啊,是说:然而结果很清楚的显示出~~)driver with passengener are ~~~~
The effect(effects) contributeto the 4,000 automobile dust(death)in the U.S. annually, that’s about the sizeof family park.
我听到的是 the size of fun with park.是不是说死亡人数差不多是一个公园容纳的人数
有些地方听的太费劲了 只能猜了   
PS:小媚去哪里了  没正确答案了
I can hear "Hallelujah chorus"

May 25th  

My grandmother was always a bit of chatty cathy. That is until she was a passenger in a car. Then she fall silent. Her reason? Driving a car is a difficult work and requires concentration, or so my grandfather told her. It turns out he had a point: drivers with passengers are 60 percent more likely to have a car accident that results in hospitalization. That’s according to research from the George Institute for international health. But as much as the passengers distract drivers, nothing beats mobile phones for increasing the risk of crashing. The institute analyzed nearly 500 serious accidents and found that the use of cell phones even hands free increase the likelihood of accidents by four times. While researchers haven’t figured out exactly how car conversations impair driving, the effects contribute to the 4000 automobile death in the US annually. That’s about the size of a friendly park. So with new cars being suited up wit TV, internet access and more cup holders, then you can image there is a Disney land of distraction inside. May be it’s time to end plud and focus our eyes and ears on the road ahead.

I can hear "Hallelujah chorus"  中Hallelujah chorus是赞美上帝的赞美诗,去祷告时大家都会一起唱的
此句话是形容,当我们遇到幸福的事情(难以完成的事情完成了,困难被击败了等),一定是上帝在暗中帮助我们.所以要感谢上帝
说白了,中国的上帝就是皇上,就是我们以前常说的"皇上万岁"差不多  :)

我是用的听写的一个软件
把音频下下来之后听写
感觉还不错,但是还是觉得用不惯
从今天开始,向lz学习
我也要坚持!

May 29, 2007: 60-Second Science

Stanley Miller died last week. Back to 1952, he performed what has become an iconical experiment in history of science. What the big question concerning history of life on the earth was, where the complex organic compound come from, that all life needs to exist. Researchers at that time had pretty good ideas that the early earth had ample of hydrogen, water, just oxygen and hydrogen, methane, which consists of carbon hydrogen, and ammonia made of just nitrogen hydrogen. Miller put water and ammonia in to flask with methane and hydrogen gas. With exact electricity which approximate energetic input ,lightening strike in this judge.  He analyzed the result of the flask of course, contain same element, nitrogen hydrogen, nitrogen, oxygen. Very interesting chemical changes have taken place. Breaking existed chemical bond and formation of new one had turned out start of it into ammonioacid, the building block of protein. And now, for a familiar notion, primino soup, from which, Complex Molecules branch was born.

And now, familiar notion of primordial soup, from which complex bio-molecules sprung, was born.
In electricity, a corona discharge is an electrical dischargebrought on by the ionization of a fluid(ps:primordial soup:) surrounding a conductor, whichoccurs when the potential gradient (the strength of the electric field)exceeds a certain value.

forerunner‘S SCIENCE TIME

[size=+1]In 1950,a graduate student (Stanley Miller) designed an experimental test for Oparin'shypothesis. Oparin's original hypothesis called for : 1) little or no freeoxygen (oxygen not bonded to other elements); and 2) C H O and N in abundance.Studies of modern volcanic eruptions support inference of the existenceof such an atmosphere. Miller discharged an electric spark into a mixturethought to resemble the primordial composition of the atmosphere. In awater receptacle, designed to model an ancient ocean, Miller recoveredamino acids. Subsequent modifications of the atmosphere have produced representativesor precursors of all four organic macromolecular classes. Miller'sfirst report of his results was in: Miller, S. L.,[size=+2]"A production of amino acids under possible primitive Earth conditions"[size=+1],Science 1953; 117: 528-529.

At the age of 20:funk::loveliness:, Stanley L. Miller did the Miller Urey experiment...........................genius
What is your age?;)


Stanley L. Miller, a scientist whose spectacular discovery as ayoung graduate student pioneered the study of the origin of life onearth, died Sunday at a hospital near his home in National City, Calif.He was 77.
The cause was heart failure, said his brother, Donald Miller.
      Dr. Stanley L. Miller in 1999.
