4、ea. In a region of China known for thousands of years of tea growing, a new crop is beginning to change the countrys landscape: coffee. This town near the Laos border is surrounded by green hills; it produces a variety of tea which is also called Puer. But the regions mild climate is also perfect fo
5、r growing Arabica coffee. And as Chinas young people move away from traditional tea in favor of the invigorating coffee, Puers farmers are catering to the demand. Yunnan accounts for 98% of Chinas coffee harvest, with half coming from the misty landscape around Puer. Today, China is the 13th biggest
6、 coffee producer in the worldrising from zero output three decades ago to 136,000 tons annually today.In April, Seattles annual Specialty Coffee Expo decided to showcase China as its portrait country of origin. It follows on the heels of Starbucks launching its first singleorigin Yunnan coffee last
7、year after eight years of partnership with Yunnan farmers.With global coffee prices at record lows, Yunnan farmers are processing beans in bespoke (定制的) ways to create distinct flavorsallowing them to enter the market of specialty coffee. “At current coffee prices, I cant even feed my family，” says
8、the farmer Yang. “My only way out is to produce specialty coffee, to make the best coffee beans.” That means letting beans dry in their cherries, thus producing a wild, fruity flavor, or allowing them to “honey” in their sugary inner layer, which adds the slight sweetness.“If I told you this was Col

The professional athlete who became a gold medalist in the Olympics for the disabled has never met a challenge she couldnt overcome, whether i
13、t was a mountain bike race or cancer.One morning in 2007, Whitmore found her leg muscles were tight when going for a jog. Thinking shed pushed herself too hard in the last race, she ignored the pain. Later at a sports camp in Arizona, she realised something was wrong. “Once I got on my bike I was so
14、 painful that it was hard to lift my legs. I flew back home to go to hospital.” What doctors found shocked them all: Whitmore had a soft tissue tumour (肿瘤) that started in the bone, and the tumour wrapped around her nerves of waist, touching several vital organs.After the surgery, Whitmore had to le
15、arn to walk again with the help of a physical doctor. She also started radiation treatment, but four months later, doctors had worse news: A scan showed the cancer was back. “This time it was more aggressive. Doctors took the rest of my nerves in the waist, and removed some tumours from my tail bone
16、.” Whitmore developed sepsis (败血症) from the surgery and endured a twomonth recovery. “My scans were coming back, showing I was clear of cancer, but now I had all of these other complications (并发症)”Today, Whitmore is a mother and cancerfree. She has won a gold medal in the Paralympics, and has set tw

Some doctors told me I would never ride anything more than a stationary bike. And yet I rode my mountain bike 104 miles climbing from 9,000 fee

20、AHumorous and unhealthy.BOutgoing and honest.CStrongminded and optimistic.DDetermined and naughty.CAnyone who commutes (通勤) by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential traffic jams. Ants also commutebetween their nests and sources of f
21、ood. The survival of their colonies (群体) depends on doing this efficiently.“The more they are, the more food theyre going to bring back. But at the same time, they might end up in a traffic jam because there are too many of them，”SebastienMotsch, a professor in Arizona State University said. When hu
22、mans commute, theres a point at which cars become dense enough to slow down the flow of traffic, causing congestion. Motsch and his colleagues wanted to know if ants on the move could also get blocked. So they controlled traffic density by constructing bridges of various widths between a colony of A
23、rgentine ants and a source of food. Then they waited and watched.The flow of ants did increase initially as ants started to fill the bridge and then stabilised at high density. But it never slowed down, even when the bridge was nearly filled with ants. The researchers then took a closer look at how
24、the behaviour of individual ants impacted traffic as a whole. That meant cautiously tracking thousands of separate ants as they made their way across the bridge.Motsch and his team found that when ants sense overcrowding, they adjust their speed and avoid entering highdensity areas, which prevents c
25、ongestion. The behaviour may be made by pheromones (外激素), the chemicals that tell other ants where a trail is. The ants also manage to avoid colliding with each other at high density, which could really slow them down.Can ants help us solve our own traffic problems? “Not likely，” says Motsch. Thats
26、because when it comes to getting from point A to point B as fast as possible, human drivers put their own goals first. Individual ants have to be more cooperative in order to feed the colony. But the research could be useful for bettering traffic flow for selfdriving cars, which can be designed to b

28、 bridges of different widths.BThey made the ants on the move.CThey watched the ants closely.DThey got the ants blocked.11What is the result of the research?AThe ants avoid entering highdensity areas.BThe ants never stop and no traffic jam happens.CThe ants sense overcrowding and adjust their speed.D
