In the western Pacific Ocean lies the deepest place on the planet — the Mariana Trench, which runs as deep as about 7 miles below the ocean’s surface. That’s greater than the height of Mount Everest measuring about 5 and a half miles above sea level.
The Mariana Trench is home to a variety of sea life. Coral reefs and underwater volcanoes are all found there. But because few humans have been able to go far into the trench, scientists know little about it.
Now they are working to change that. Recently, the Okeanos Explorer has been on an exploration there. Remotely operated vehicles sent out from it are taking videos of life in its deepest, darkest areas. Scientists around the world, along with the general public, can watch the videos in real time. These videos are showing the most mysterious parts of the ocean. Much of the area that the Okeanos Explorer is exploring has been protected since 2009 as part of the Marianas Trench Marine National Monument. Covering more than 95,000 square miles, it is one of the world’s largest marine protected areas.
It’s very dark, so the animals must use many other senses other than sight to understand their surroundings, find food and escape from enemies. The water is also very cold — slightly above freezing — and its pressure is extremely high. That means only certain animals can live there, like shrimp, crabs, and starfish.
So far, the expedition’s cameras have filmed a variety of rarely seen deep-sea creatures, including ghost sharks, huge lobsters, and sea pigs. Perhaps the most amazing sight is beautiful red jellyfish that scientists have never seen before.
Scientists hope this expedition will help them unlock the mysteries of the Mariana Trench. They’ll learn about the deep-sea animals and plants found there. They’ll also study its unique features, including underwater mountains, mud volcanoes, and hot springs produced by the volcanoes.
They say that this knowledge will also help scientists better understand how the deepest part of the ocean affects the rest of the world. "The ocean plays a role in the air we breathe, the food we eat, and the transportation of the goods we buy — not to mention the weather and climate change," a scientist said. "The deep sea may also hold cures for diseases. How will we know what is out there if we aren’t looking into it?"

China says 16 endangered finless porpoises（江豚）have been found dead since the beginning of the year and experts blame water pollution and climate change for pushing the species toward extinction．
The freshwater porpoise-popularly known in Chinese as the"river pig"-mainly lives in China's Yangtze River and two lakes linked to the river．
Authorities（官方）have discovered 10dead porpoises in Dongting Llake in the central province of Hunan since March, according to a statement by the government of Yueyang City, which is located on the lake's shore． Another six dead porpoises have been found in Poyang Lake in the eastern province of Jiangxi since the beginning of the year． Experts warn that the species will be extinct within a matter of years．
Wang Kexiong, a researcher at China's Institute of Hydrobiology, said water pollution, shipping and sand dredging（挖掘）were all possible contributing factors to the recent deaths．
Many rivers in China have become heavily polluted with poisonous waste from factories and farms-pollution blamed on more than three decades of rapid economic growth and slow enforcement（实施）of environmental protection laws．
The report said climate change also could be to blame as the dry weather has caused water levels to drop and makes it more difficult for the porpoises to find food． Tests have shown that some of the porpoises are believed to have died of starvation（饥饿）．
In 2006, China was estimated（估计）to have only 1,200 finless porpoises left． That same year, the Baiji-a freshwater dolphin also native to the Yangtze River-was declared extinct． Earlier this year, a survey found just 65"river pigs"in Dongting Lake and 300-400 in Poyang Lake．
Following the recent deaths, Yueyang City promised to investigate and increase protection of the remaining porpoises in Donting Lake．

People can't see you when you're speaking on the phone,but they can hear you．So,the way you speak is especially important．In fact,researchers have calculated that 80% of communication over the phone is through your tone of voice； and only 20% is from the words you use．Here are our top tips on how to speak over the phone．
Facial Expressions
Your facial expression can influence your voice．For example,if you smile,your voice will sound warm and friendly,just the opposite,if you have an angry look on your face,it can make you sound unpleasant．
Volume
If you speak too loudly,you could sound angry．And if you speak too softly,it'll be difficult to hear you．So,speak loudly enough to be heard clearly,but not so loud that you're shouting．
Pace
The pace of your voice is how quickly you speak．And this can show how you feel．For example,an angry person might speak faster than normal．Or a downhearted person might speak very slowly．Try speaking a little more slowly than normal．This will make you sound confident,and it'll make it easier for the other person to understand you．
Gestures
Gesturing can influence the tone of your voice．When you gesture,you bring more air into the lungs,which can make your voice sound warmer．Gestures are also useful to help you stress the right words or even find the words you need．The best thing about gesturing during a phone call is that no one can see what you're doing,so you can gesture as wildly as you like!
Movement
If you're feeling nervous,stand up and move around．It will reduce the nervousness in your body and help your voice to sound more confident．
Pauses （停顿）
Using pauses every now and then can help you to slow down．This will make you sound more confident and in control．Also,if you pause after giving some new information,it'll give the other person time to understand it．At the same time,listen to how the other person uses pauses．They could tell you something about the speaker's feeling．For example,when a speaker is really angry,he might use pauses and says,"I…am…so…angry…"
