【推荐3】Marco Springmann and his colleagues, at the Oxford Martin School's Future of Food Programme, built computer models that predicted what would happen if everyone became vegetarian by 2050. The results indicate that if the world went vegan, the greenhouse gas emissions declines would be around 70%.

In the US, for example, an average family of four emits more greenhouse gases because of the meal they eat than from driving two cars——but it is cars, not steaks, that regularly come up in discussions about global warming.

Food, especially livestock, also takes up a lot of room. 68% of agricultural land in the world is used for livestock. When these lands become grasslands and forests, they would capture carbon dioxide and further ease climate change.

However, if the whole world went vegan, there would be negative effects too. First, it is necessary to keep livestock for environmental purposes. "I'm sitting here in Scotland where the Highlands' environment is very man-made and based largely on grazing by sheep," says Peter Alexander, a researcher in socio-ecological systems modeling at the University of Edinburgh. "If we took all the sheep away, the environment would look different and there would be a potential negative impact on biodiversity. "

Plus, meat is an important part of history , tradition and cultural identity. Numerous groups around the world give livestock gifts at weddings, celebratory dinners such as Christmas with turkey or roast beef.

And nowadays, moderation in meal-eating's frequency and portion size is key to solving these conflicts. "Certain changes would encourage us to make healthier and more environmentally friendly dietary decisions," says Springmann, "like putting a higher price lag on meat and making fresh fruits and vegetables cheaper. "

In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock industry. What is lacking is the will to implement those changes.

【推荐1】Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”

Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.

Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?

Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. As a result, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!

Once, a young school boy was caught in a fire accident in his school and was assumed that he would not live. His mother was told that he was sure to die, for the terrible fire had destroyed the lower half of his body. Even if he were to survive, he would be lame throughout his life.

But the brave boy did not want to die nor did he want to be lame.  Much to the amazement of the doctor, he did survive. But unfortunately from his waist down, he had no motor ability. His thin legs just hung there, lifeless. Eventually he left the hospital. But his determination to walk was unshakable. At home, when he was not in bed, he had to stay in a wheelchair. One day, he threw himself from the chair and pulled himself across the grass, dragging his legs behind him. He reached the fence, raised himself up and then began dragging himself along the fence, firmly determined. He did this every day, with faith in himself that he would be able to walk unaided. With his iron determination, he did develop the ability to stand up, then to walk on and off, then to walk by himself and then to run.

He began to walk to school, and then run to school, to run for the joy of running. Later in college he was on the track team.

In February 1934, in New York City's Madison Square Garden, this young man who was not expected to survive, who would surely never walk, who could never hope to run-this determined young man, Dr. Glenn Cunningham, ran the world's fastest mile.

A good example of the power of positive thinking and faith in one's self, Glenn Cunningham continues to be an inspiration for many, and his story, a brilliant evidence to how one can bounce back even when all difficulties are piled against one, to the degree that death seemed the preferable option.

A．Strengthen determination	B．Stand up after failure
C．Go after dreams	D．Face difficulty bravely

【推荐3】Looking at Rosa Ferrigno's new suit, you could swear it was knitted(织) with regular yarn(毛线).It’s only when you touch it and hear the characteristic rustling(沙沙声 )of plastic that you realize there's something special about it.In fact, the suit is made out of over 300 plastic grocery bags.

Ferrigno, who once worked as a tailor before starting a family, got the idea for her unique hand-made suit last August.She was at a family picnic and saw on of the other guests carrying a purse made from re-purposed plastic bags.It attracted her, so she and her daughter searched for instructions on how to make one on You Tube.The 75 -year-old ended up making a purse from colorful plastic bags.But that was only the beginning.After finishing her second plastic bag purse, Ferrigno realized she needed something to match it with, so last November she told her daughter she was going to make a skirt and jacket suit out of plastic bags, as a winter project.

Rosa started by cutting up the plastic bags into strips(A.)and then tying them together to make longer, yarn- like strips that could be knitted.But to knit the plastic yarn, she needed that didn't exist on the market so she made them on her own.

The suit took Rosa two months to complete.The jacket was made out of 170 plastic bags, and the skirt required another 140.Although she didn’t even use a pattern when knitting the impressive suit, it ended up fitting her perfectly, and when she finally showed it off at the supermarket earlier this month, everyone went crazy.

“We love it when our customers reuse or recycle grocery bags, but never have we seen a work of art like Rosa's! It's really fantastic "Jo Natale, the supermarket chains vice president of media relations, said.
