12．Dolphins are not fish，but warmblooded animals．They live in groups，and speak to each other in their own language．In this way they are like other animals，such as bees and birds．But dolphins are very different from almost all land  animals．Their brain is nearly the same size as our own，and they live a long time-at least twenty or thirty years．
Like some other animals，dolphins use sound to help them find their way around．They also make these sounds to talk to each other and to help them find food．We now know they do not use their ears to receive these sounds，but the lower part of the mouth，called the jaw．
Strangely，dolphins seem to like man，and for thousands of years there have been stories about the dolphin and its friendship with people．There is a story about sailors in the 19th century．In a dangerous part of the sea off the coast of New Zealand，they learnt to look for a dolphin called Jack．From 1871to 1903 Jack met every boat in the area and showed it the way．Then in 1903 a passenger on a boat called the Penguin shot and wounded（伤害）Jack．He recovered and for nine years more continued to guide all ships through the area-except for the Penguin．
Today，some people continue to kill dolphins，but many countries of the world now protect them and in these places it is against the law to kill them．

7．Sitting for more than three hours a day can decrease a person's life expectancy（预期寿命）by two years，even if her or she is physically active and gets rid of （摆脱）dangerous habit like smoking，according to a study．Watching TV for more than two hours a day can worsen that problem，decreasing life expectancy by another 1.4 years．
The analysis comes just two years after Australian researchers found that people who said they watched TV for more than four hours a day were 46% more likely to die of any cause than people who said they spent less than two hours a day watching TV．Those watching TV more than four hours a day were also 80% more likely to die of cardiovascular （心血管的） disease．"Long-sitting behavior is something we need to take note of beyond telling people to get 30 minutes of activity a day，"said Peter T．Katzmarzyk，one of the lead researchers．But while the evidence of illnesses is increasing，it remains difficult for many people to find time to get on their feet，especially if they do desk jobs．
"Try to stand as much as you can，"Dr Katzmarzyk said．"Typically when you are on the telephone you can stand and use the speakerphone．Instead of e-mailing someone in the office，just get up and so to talk to them．"However，Dr Katzmarzyk added，standing shouldn't be alternative to exercising，but an alternative to sitting．"Several studies show that when you're sitting，your leg muscles are completely inactive，"he said．"When you're sitting and completely inactive，this is when you run into trouble managing blood sugar．"

B．It's a bad behavior worth considering seriously．

A．phone your friends and talk about your problem
