The world39。s cities produce 2 billion tons of trash every year. By the year 2050 that number is expected to rise to 3 billion tons. The World Bank estimates that the largest amount of trash today, about 44 percent, is plastic. But we often have to buy packaged goods. And often that packaging is made of plastic. Now, that may be changing. A new environmentallyfriendly shopping model was recently launched at the World Economic Forum in Davos, Switzerland. This shopping model, called Loop, aims to replace throwaway containers with reusable ones. Loop is the idea of Terra Cycle, an Americanbased recycling pany. Its chief, Tom Szaky told the Associated Press (AP) that removing plastics from the ocean is not enough. He said the point is to get away from singleuse packages. Szaky said that Loop is the future of shopping. But it es from an idea of the past. He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste. Jennifer Morgan from the environmental nonprofit organization Greenpeace also joined in the discussion about Loop at Davos. She said that Greenpeace weles the aim of the Loop Alliance to move away from throwaway culture and disposability. But Morgan questioned whether panies worldwide are ready to change their business models. Loop is set to launch later this year in three eastern . states, and also in Paris, France and some of the surrounding area. Then Loop plans to expand to the . West Coast, Toronto, Canada and Britain by the end of this year or 2020.（1）What does the author intend to do in Paragraph 2?

It was thought impossible. Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high. The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模擬)10w, medium, and highaltitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel. Birds already have a better heart and lungs than mammals for sustained
