Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn't know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

    But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

    Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

    Twenty –five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.

    The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

    As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

    Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii.

    The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

    To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos（胚胎）. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

    Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that can be cheaply extracted, especially in countries that can't afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

    The rabbits are expected to have the same life span as their non-glowing counterparts（副本）, but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

    "To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

    Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

    All over the world people enjoy sports, Sports help to keep people healthy and happy, and to live longer.

    Many people like to watch others play games. They buy tickets or turn on their TVs to watch the games. Often they get very excited when "their" player or team wins.

    Some sports are so interesting that people everywhere go in for(参加)them. Football, for example, has spread (展开)around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy! And think of people in cold countries. Think how many love to skate or ski(滑雪)in Japan, Norway or Canada.

    Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. Water-skiing is one of the newest in the family of sports.

    People from different countries may not be able to understand each other, but after a game together they often become good friends. Sports help to train(培养，训练)a person's character(性格，品格).One learns to fight hard but fight fair, to win without pride and to lose with grace(胜不骄，败不馁).

    Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.

    The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen "at risk" patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: "I am so excited about this form of technology." Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. "I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a completely new example in the way we manage healthcare."

    The technology is the brainchild of Dr Vishal Nangalia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.

    He found the technique forecast outcomes of patients with kidney problems with up to 95 per cent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. "This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient." Prof Young said, "Instead of waiting for people to get worse, we will be able to treat them earlier."

    When I was in primary school, I had an argument with a boy in my class. I thought that "I" was right and that "he" was wrong. But he thought "I" was wrong and "he" was right.

    The teacher asked him to stand on one side of her desk and me on the other. In the middle of her desk was a large and round ball. I could see it was black. She asked what color the ball was. "White," he answered.

    I couldn't believe the boy's answer, because from my side it was obviously black!

    The teacher told me to stand in the boy's place and told him to stand in my place. We changed our places, and then the teacher asked me what color the ball was. I had to answer, "White."

    It was a ball with two different colors. From his side it was white. Only from my side was it black.

    My teacher taught me a very important lesson that day: You must stand in other people's shoes and look at the situation through their eyes in order to truly understand their view.
