Apologizing the Right Way to a Friend
Why are apologies so difficult？ Saying you are sorry can be one of the most difficult things you do． But we all make mistakes， so you'll probably have an occasion when you need to apologize．
Perhaps you had a big blow up and realized later you reacted poorly．1. Whatever the reason，apologizing can help you both heal and move on from the situation．
2. First， you acknowledge that you did something wrong． With an apology，you take responsibility for your actions，which allows your friend to forgive you． Second，an apology gives you sincerity as a friend．3.，but that doesn' t mean you still shouldn't apologize．
Now， what are elements of a proper apology？ 4.，depending on what the offense was，where it was done， and who you are apologizing to． In general， a good apology should include the following： a request for their attention，an acknowledgment of what happened，sincerity in admitting you did something wrong and the words． "I'm sorry" or "I apologize．"
Here are things never to say when apologizing． Note that the art of apologizing involves taking responsibility． Never apologize as a way to "shut someone up" when they are saying you hurt their feelings and you don't think you did．5.，you should talk things through with your friend until you see why they are hurt or how you came across． You'll really need to self﹣reflect so you can see things from your friend' s point of view．
A． When you make your apology in person
B． If you really believe you did nothing wrong
C． Apologies benefit friendships in a variety of ways
D． The way you apologize is going to be slightly different
E． Or maybe you just didn't show support when you needed to
F． Apologizing the right way，however， may take a little practice
G． Sometimes our pals forgive us easily for the minor things we do wrong
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," says Fadel Adib，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.

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." explains Ayers-Elliott. “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. "When speaking of the key to my success，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. ”
"It' s a model that can easily be learned in other places and I' m looking forward to seeing some of our current partners do just that——to take what they have learned here and spin it off in other communities,"Ayers-Elliott remarks. She is now looking forward to developing an agritourism aspect to the 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.

Created in 1998 by Casey and Shelley Black， the Northern Lights Wildlife Wolf Center focuses on not only rescuing young abandoned wolves but educating the public． Unlike other centers， you can actually walk with the wolves and have exciting， hands﹣on interaction with them here． And so， we gathered one late winter morning to learn， prepare and walk．
Scrappy and Flora，our wolves that day，were brought to the center when only a few days old． "They lived in the house with us for the first several months． We treated them like human babies， fed them 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．
1.How is the Northern Lights Wildlife Wolf Center different from others？
A. It trains and educates wild wolves．
B. It aims to rescue young abandoned wolves．
C. It raises wolves for commercial purposes．
D. It allows visitors to take a walk with wolves．
2.What can be inferred from Shelley and Casey's explanation in Paragraph 2？
A. The walk can be potentially dangerous．
B. The wolves have lost all their wildness．
C. People should get close to the wolves actively．
D. The wolves can read people's mind like human babies．
3.Why did Flora behave like that when she saw the author on the logging road？
A. To express curiosity．
B. To show friendliness．
C. To attract attention．
D. To seek companionship．
4.Why do Casey and Shelley organize such an adventure？
A. To advertise the center．
B. To publicize wolf hunting．
C. To promote environmental protection．
D. To clarify some conventional views of wolves．
