Obesity Causes Global Warming

    The list of ills attributable to obesity keeps growing: Last week, obese people were accused of causing global warming.

    This conclusion comes from Sheldon Jacobson of the UniversityofIllinois, US, and a doctoral student, Laura McLay. Their study calculates how much extra gasoline is needed to haul fat Americans around. The answer, they say, is a billion gallons of gas per year.  ____1____

    There has been calls for taxes on junk food² in recent years.  ____2____"We tax cigarettes partly because of their health cost," Schmidt said. "Similarly, leading a lazy life style will end up costing taxpayers more."

    US political scientist Eric Oliver said his first instinct was to laugh at these gas and fast food arguments. But such claims are getting attention.

    At the US Obesity Society"s annual meeting, one person correlated obesity with car accident deaths, and another correlated obesity with suicides.  ____3____"The funny thing was that everyone took it seriously." Oliver said.

    In a 1960s study, children were shown drawings of children with disabilities and without them, and a drawing of an obese child. They were asked which they would want for a friend?  ____4____

    Three researchers recently repeated the study using college students. Once again, almost no one, not even obese people, liked the obese person. "Obesity was stigmatized." the researchers said.

    But, researchers say, getting thin is not like quitting smoking. People struggle to stop smoking, and, in the end, many succeed. Obesity is different. But, not because obese people don"t care.  ____5____Genes also play a part.

Einstein Named "Person of the Century"

    Albert Einstein, whose theories on space time and matter helped unravel the secrets of the atom and of the universe, was chosen as "Person of the Century" by Time magazine on Sunday.

    A man whose very name is synonymous with scientific genius，Einstein has come to represent more than any other person the flowering of the 20th century scientific thought that set the stage for the age of technology.

    "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic，but technological 一 technologies that flowed directly from advances in basic science. ” wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein"s significance ____1____    

    Time chose as runner-up President Franklin Roosevelt¹ to represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi2 as an icon for a century when civil and human rights became crucial factors in global politics.

    "What we saw was Franklin Roosevelt embodying the great theme of freedom"s fight against totalitarianism, Gandhi personifying the great theme of individuals struggling for their rights, and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom. ” said Time Magazine Editor Walter Isaacson.

    Einstein was born in Ulm,Germanyin 1879. ____2____He was slow to learn to

speak and did not do well in elementary school. He could not stomach organized learning and loathed taking exams³ ？

    In 1905, however, he was to publish a theory which stands as one of the most intricate

examples of human imagination in history.   ____3____ Everything else — mass， weight, space, even time itself — is a variable. And he offered the world his now-famous equation ： energy equals mass times the speed of light squared — E = mc².

     ____4____  "There was less faith in absolutes, not only of time and space but also of truth and morality."

    Einstein"s famous equation was also the seed that led to the development of atomic energy and weapons. In 1939, six years after he fled European fascism and settled at Princeton University, Einstein，an avowed pacifist⁴，signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did. ____5____Einstein did not work on the project.

    Einstein died inPrinceton,New Jerseyin 1955.

练习：

A "Indirectly, relativity paved the way for a new relativism in morality, art and politics. ” Isaacson wrote in an essay explaining Time"s choices.

B How he thought of the relativity theory influenced the general public"s view about Albert Einstein.

C ” Clearly, no scientist better represents those advances than Albert Einstein. ”

D Roosevelt heeded the advice and formed the "Manhattan Project" that secretly developed the first atomic weapon.

E In his early years, Einstein did not show the promise of what he was to become.

F In his “ Special Theory of Relativity ”，Einstein described how the only constant in the universe is the speed of light.

Across the Deserts

　　The SaharaDesertis the largest desert in the world. It stretches across Africa fromSenegaltoEgypt. TheSaharaDesertis an unfriendly environment. During the day it"s very hot, and at night it’s sometimes very cold. It is also difficult to find water in theSahara.

　　In 2006, Kevin Lin, Ray Zahab, and Charlie Engle decided to do something very difficult. They made the decision to run across the Sahara Desert 4,300 miles (6,920km). It seemed impossible to do, but they wanted to try. The three men liked to test themselves, and this would be a very big test.

　　On the morning of November 2, Kevin, Ray, and Charlie started their trip across theSahara. Every morning they began running at 5:00. At11 a.m. they stopped and rested until 5 p.m. Then they ran again until 9:30 in the evening. Each day they ran about 40 miles (64 km). Every day it was the same thing. They got up and ran. They listened to music on their iPods, and they ran and ran.

　　Kevin, Ray, and Charlie needed to eat a lot of food during their trip. Most people need about 2,000 calories of food each day. Kevin, Ray, and Charlie needed between 6,000 and 9,000 calories every day. That"s a lot of food! They also needed to drink a lot of water.

　　The three men had some problems on their trip, and many times they wanted to quit and go home. It was often very hot (140°F/60°C) during the day, and the heat made them sick. Their legs and feet hurt. Sometimes it was very windy, and they couldn"t see. One time they got lost. But they didn"t quit. After 111 days, Kevin, Ray; and Charlie successfully finished their trip across theSaharaDesert. They hugged each other and put their hands in the water of theRed Sea. Then they ran to a hotel to take a long shower.
