Last month our class organized a hiking along the Chaobai River，which run through Hebei， Beijing and Tianjin． Much to my disappoint， I found the river was serious polluted． At that moment， I was determined to do what I could protect it． First， under my teacher's help， I used the equipments from the school lab to test the quality of the river water． But then，I used the data I had collected it to analyze the pollution of the water． Finally，I write a report on the pollution of the river to the local government． I also gave a presentation in class where I suggested that we must make small changes to protect our water resources．

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.
