15．Does happiness have a scent？
When someone is happy，can you smell it？

You can usually tell when someone is happy based on seeing them smile，hearing them laugh or perhaps from receiving a big hug．But can you also smell their happiness？Surprising new research suggests that happiness does indeed have a scent，and that the experience of happiness can be transmitted through smell，reports Phys．org．
For the study，12 young men were shown videos meant to bring about a variety of emotions while researchers gathered sweat samples from them．All of the men were healthy and none of them were drug users or smokers，and all were asked to abstain from drinking or eating smelly foods during the study period．
Those sweat samples were then given to 36equally healthy young women to smell，while researchers monitored their reactions．Only women were selected to smell the samples，apparently because previous research has shown that women have a better sense of smell than men and are also more sensitive to emotional signaling-though it's unclear why only men were chosen to produce the scents．
Researchers found that the behavior of the women after smelling the scents-particularly their facial expressions-indicated a relationship between the emotional states of the men who produced the sweat and the women who sniffed them．
"Human sweat produced when a person is happy brings about a state similar to happiness in somebody who breathes this smell，"said study co-author Gun Semin，a professor at Koc University in Turkey．
This is a fascinating finding because it not only means that happiness does have a scent，but that the scent is capable of transmitting the emotion to others．The study also found that other emotions，such as fear，seem to carry a scent too．This ensures previous research suggesting that some negative emotions have a smell，but it is the first time this has proved to be true of positive feelings．
Researchers have yet to isolate （分离） exactly what the chemical compound for the happiness smell is，but you might imagine what the potential applications for such a finding could be．Happiness perfumes，for instance，could be invented．Scent therapies （香味疗法） could also be developed to help people through depression or anxiety．
Perhaps the most surprising result of the study，however，is our broadened understanding of how emotions get communicated，and also how our own emotions are potentially managed through our social context and the emotional states of those around us．
28．What is the main finding of the new research？C
A．Men produce more sweats．
B．Negative emotions have a smell．
C．Pleasant feelings can be smelt out．
D．Women have a better sense of smell．
29．The underlined part"abstain from"in Paragraph 3probably meansA．
A．avoid B．practice C．continue D．try
30What is the application value of the new research？B
A．Perfumes could help people understand each other．
B．Some smells could be developed to better our mood．
C．Perfumes could be produced to cure physical diseases．
D．Some smells could be created to improve our appearance．
31We can learn from the last paragraph thatD．
A．happiness comes from a scent of sweat
B．positive energy can deepen understanding
C．people need more emotional communication
D．social surroundings can influence our emotions．

2．It is not our mistakes that define who we are； it is how we __ from those mistakes that counts．（　　）

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？

25．Why do people wear fitness trackers while running？C
A．To measure their blood pressure．
B．To tell them the right direction．
C．To report the amount of exercise．
