and slept with them,” said Shelley. So, they are totally used to people. However, these are wild animals. For that reason, Shelley and Casey explained, the walk is totally on the wolf’s terms. “We don’t approach them, but if they come up to us, we can touch them. ”
With all this in mind, we headed for the woods. We were walking on a logging road when suddenly，Flora, all 60 pounds of her，hurried up to me and raised up on her legs. She was almost as tall as me. As she leaned in, put her huge muddy paws on my shoulders and sniffed my face, apparently she was saying hello in wolf talk.
We walked farther, maybe half a mile, while Scrappy and Flora dashed in and out of the woods stopping to occasionally roll in the snow，dig for this or that and just play. Then we all headed into the trees to a picturesque stream where the wolves splashed，drank and had a great time.
One could point out that this whole adventure was staged and quite artificial. But the purpose, Casey and Shelley said，is to explain the wolves' place in the environment and，primarily，to let people know wolves don' t have to be universally feared—they really don' t hide secretly in the woods just waiting to eat people，but they' d rather avoid people，for the most part.

Have you ever heard of agritourism where you can experience farm life? If not, Dr. Cindy Ayers-Elliott will tell you the real story of Foot Print Farms.
The original concept of building Foot Print Farms was simple. When Ayers-Elliott returned to her hometown after graduation，she didn' t have to look any further than her state' s alarming health statistics to find a mission. Everywhere she turned, there were reports of high blood pressure, diabetes, obesity and heart disease. “The problem was already identified.\“Too many Mississippians were seriously unhealthy and it didn’t take research to see that. And many of the state' s greatest health challenges could directly result from poor diet. ”
These days，Foot Print Farms, which started with a few raised beds of herbs and vegetables, is making fresh, naturally grown food. \，the co-op model works because we share the work and rewards，” notes Ayers-Elliott. “ A perfect example is the Wingfield High School football team. To earn the money for equipment and other items, players committed to working five hours a week on the farm，and by the end of the summer they had produced 1，000 melons and the profits from their sales helped to buy weights，T-shirts，sweat suits and pregame meals. But the lessons they learned about the rewards of hard work and working together to accomplish something were even more valuable products of their efforts. ”
\current partners do just that——to take what they have learned here and spin it off in other communities,\farm, where visitors can experience farm life, learn new skills and take with them seeds of inspiration they can sow in their own communities when they return home.
28. What made Ayers-Elliott set up Foot Print Farms? A. The problems faced by local farmers. B. Her further research into heart disease. C. The failure of her career after graduation. D. The health state of people in her hometown.
29. Why does the author take the football team as an example? A. To advocate the concept of independence. B. To stress the importance of teamwork. C. To support the idea of co-op model. D. To explore the key to success.
30. What is Ayers-Elliott' s attitude towards the future of Foot Print Farms? A. Optimistic. B. Skeptical. C. Cautious. D. Ambiguous. 31. What is the main idea of the text?
A. Naturally grown food benefits people’s health. B. Food Print Farms is making a difference in Mississippi. C. Ayers-Elliott encourages people to experience farm D. Agritourism is becoming increasingly popular in America.

We can video chat with astronauts aboard the International Space Station and watch live footage from the frozen heights of Everest. But communicating with a submarine (潜艇）or a diver is not so easy. The lack of practical methods for sharing data between underwater and airborne devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar (声呐）signals used by underwater sensors reflect off the surface of the water rather than reaching the air.
Now，researchers at MIT have developed a method with the potential to revolutionize underwater communication. “What we’ve shown is that it’s actually feasible to communicate from underwater to the air,\，a professor at MJT’ s Media Lab，who led the research.
The MIT researchers designed a system that uses an underwater machine to send sonar signals to the
surface, making vibrations (震动)corresponding to the ls and Os of the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. It has any number of potential real-world uses, Adib says. It could be used to find downed planes underwater by reading signals from sonar devices in a plane' s black box and it could allow submarines to communicate with the surface.
Right now the technology is low-resolution. The initial study was conducted in the MIT swimming pool at maximum depths of around 11 or 12 feet. The next steps for the researchers are to see if TARF is workable at much greater depths and under varying conditions—high waves, storms， schools of fish. They also want to see if they can make the technology work in the other direction— air to water.
If the technology proves successful in real-world conditions, expect “texting while diving” to be the latest underwater fashion.
32. What does the author mainly talk about in Paragraph 1? A. The future of video chat underwater and in air. B. The frustrations of developing underwater devices. C. The difficulty of communication from water to air. D. The current situation of communicating with a submarine. 33. What does the underlined word “feasible” mean? A. Achievable. B. Convenient. C. Changeable. D. Alternative. 34. What do we know about TARF? A. It is widely used to find downed planes. B. It can work well at great depths underwater. C. It is an underwater machine that sends signals. D. It can send，receive and read signals from underwater. 35. What is the best title for the text? A. The Real-world Uses of Sonar Technology B. Full Water-to-air Communication Closer to Reality C. A Breakthrough in the Application of Video Chat D. TARF Becoming a New Means of Communication 第二节（共5小题；每小题2分，满分10分）
