●你从中获得的启发．

　　Last week，I visit two painting classes at a primary school．In one class a student called Amy dipped her feet in ink and made a painting out of footprints．By contrast，the same student used a brush to make a beautiful landscape painting．
　　The two paintings both intrigued me．They reminded me of a famous saying"Keep your eyes on the stars and your feet on the ground．"The first painting represents that we should remain grounded and be cautious of being carried away with temporary success．
　　Success needs more than being simply down-to-earth，which also need dreams．The second painting embodied the reach of our dreams．Instead of ignoring the gleam of light that flashes across our mind，we'd better trust that the gleam and the spark will one day shine if we have faith in ourselves．
　　So we should dream big and act small．Only by doing so，can we really make our dream come true．．

12．Lately，everywhere you look，people are running around with fitness trackers on their wrists．Along with a smartphone and an accompanying app，these trackers can report how many calories you've burned and the distance you've traveled．Still curious about yourself？You can also learn the number of stairs you've climbed and steps you've taken，metrics（度量）it had never occurred to me to wonder about．
Not one to resist peer pressure，however，I paid $100for a Fitbit Flex．I chose that brand on  the basis of research：asking my friend Sari which tracker she used．
The Fitbit website offered instructions on setting up my new tracker．I entered my height  and gender（性别）and certain information I considered none of its business：birth date and  weight．Then I established goals．The American Heart Association recommends we all walk 1 0，000steps a day-about five miles，and so does Fitbit．I decided 6，000steps was a good place for me to start．
I changed my tune when，on day one，I hit 6，000steps and tiny LED lights flashed on my  wristband．Confident enough now，I went back to my phone and upped my goal to 8，000steps．
OK．So I got a little obsessed（着迷）．On day five at a department store，I decided to check  my progress．My target number was just 275steps away!I walked around the dress department  watching my smartphone register each step I took．I hate to tell you how much pleasure this gave me．
Now I always wear my tracker，not because I've grown to love fitness but because I like  being trendy and self-absorbed．Last night I was leaving a restaurant when Fitbit emailed to  congratulate me on walking more than 10，000steps．Who wouldn't love a tool that turns your  every footstep into an accomplishment？

12．Why do men die earlier than women？The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age．
The largest study of the effects of ageing on the heart has found that women's longevity may be linked to the fact that their hearts do not lose their pumping power with age．
"We have found that the power of the male heart falls by 20-25percent between 18and 70years of age，"said the head of the study，David Goldspink of liverpool john moores university in the UK．
"Within the heart there are millions of cells that enable it to beat．between the age of 20and 70，one-third of those cells die and are not replaced in men，"said Goldspink．"this is part of the ageing process．"
What surprises scientists is that the female heart sees very little loss of these cells．A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's．
"This gender difference might just explain why women live longer than men，"said Goldspink．They studied more than 250 healthy men and women between the ages of 18 and 80，focusing on healthy persons to remove the confusing influence of disease．"The team has yet to find why ageing takes a greater loss on the male heart，"said Goldspink．
The good news is that men can improve the health of their heart with regular exercise．goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age．
