    Researchers following tiger sharks off the southern coast of Belize couldn't believe their eyes when they recently caught a different kind of fish.It turned out to be a Greenland shark，which is typically found in the Arctic and can live to be about 400 years old.
   The team of scientists thought the shark was dead when they finally pulled it to the surface.Unlike the tiger sharks they saw，this particular shark had black，worn-looking skin and pale blue eyes.Devanshi Kasana，a Ph.D．candidate at the Florida International University's Predator Ecology &；Conservation Lab，said the shark looked "really old".
   There was no doubt that the discovery was unexpected.Kasana said， "As soon as it entered our field of vision，we saw a black figure that was getting bigger and bigger.When it came to the surface，none of the crew with all of their combined fishing experience had seen anything like that." She said the discovery was especially exciting.She wondered how on earth these sharks，which were thought to mainly exist in the Arctic，could be found in the tropics as well.
   Greenland sharks can be several hundred years old.The reason for their long life may have something to do with their speed of growth，which is very slow.Greenland sharks grow approximately one-third of an inch per year and can grow to more than 20 feet in length.And researchers believe the sharks don't reach sexual maturity until sometime after the first 100 years of their life.
   According to Kasana，some scientists have theorized that the Greenland sharks can be found across the globe，if one knows where to look.They love cold water，which is why they're found in the Arctic.However，they've also been discovered as far south as off the coast of Georgia，thousands of feet beneath the ocean surface.
   The theory is that the closer the sharks are to the equator，the deeper researchers have to go to find them.And they go deep over 7，000 feet down，according to NOAA．

2．How to protect your ears You and your friends are leaving a concert on a Friday night.When you get outside，your ears are ringing.You have to shout to be heard. （1）

So no harm done…right？
   Not quite.Temporary buzzing may be easy to ignore，but repeated exposure to loud noise will eventually cause serious and irreversible（不能治愈的）hearing loss.A new study conducted by researchers at Brigham and Women's Hospital in Boston shows that one in five people between the ages of 12 and 19 are experiencing slight hearing loss，and one in 20 have mild hearing loss.（2）

But the good news is that there are plenty of ways you can protect your ears from further damage - and still listen to the music you love.
   Ask around.Put your earbuds in or your headphones on，and then ask a friend next to you whether or not he or she can hear what you're listening to.（3）

Turn it down.
   Buy noise-canceling headphones.A pair of earbuds or headphones that fits comfortably will limit outside noise so that you can hear your music better at lower volume.
   Take breaks. （4）

So when listening to music，take your headphones off for 15 or 20 minutes and let your ears enjoy the quiet.
   （5）

You can buy a cheap pair at any drugstore as an easy way to lower volume at concerts or while playing or practicing your own music without changing the quality of the sound.

A.Use earplugs.
B.Keep the volume below 70 percent.
C.If the answer is yes，your music is too loud.
D.But by morning，your hearing is totally back to normal.
E.Like every other part of your body，your ears need rest.
F.Unfortunately，there's no way to get back hearing you've already lost.
G.The exposure to noise is louder and longer than in an previous generation.
