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．

B．Some smells could be developed to better our mood．

31We can learn from the last paragraph thatD．
A．happiness comes from a scent of sweat
B．positive energy can deepen understanding

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．
D．To email information to others．

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．

17．Many people give up studies because of money，but they have not got the realization that they need studies more than ever because of their poverty．Without studying，how could you change your fate？The final result may be that you are always short of money．I have been long holding a view that you can save money in every aspect in your life but not in your study．
I used to save every penny when I was studying abroad and bought everything as cheap as possible．When it came to textbooks，I would never think about saving money but bought it without the least hesitation even though it might cost me almost 70euros．My classmates might borrow my books to copy，but I thought it to be time-consuming and I would easily get some pages lost．Besides，it was because I knew that the book was bought at a high price that I would try my best to finish it，while my classmates might put it away after flipping through a few pages．
It is the same with studies．When you use a lot of money trying to learn a language or a skill，and the money was earned with your hard work or was even borrowed from others，would you give it up easily？For a rich student and a poor student who spent the same money for a course，will their attitudes towards the course are the same？Definitely not!And I can claim for sure that the poor student would study harder than the rich student．
Moreover，from my students'case，I also see a common problem in our society：When coming across difficulties，the first thing popping up in our mind is not to think about how to try them，but to give up．Many people would feel headache when meeting a small problem and then  amplify the problem to find an excuse of giving up．Actually what we need to do is not fearing the problem but trying every means to solve it．When you get addicted to this habit，no matter what you do，you will not succeed，because everything you do will have its own problems，whether small or big．

32．Which of the following is TRUE according to the article？D
A．Even if we don't study，we can change our fate．
B．The author used to spend little money in buying books．
C．The poor students'and the rich students'attitudes towards a course are the same．
D．We should try our best to solve the problems that we face．
33．Why didn't the author borrow books from his classmates to copy？C
A．Because he was a rich students．
B．Because those books were not what he needed．
C．Because it might be time-consuming and he would easily get some pages lost．
D．Because he would try his best to finish reading it．
34．In the fourth paragraph，the underlined word"amplify"most probably means"B"．
A．ignore           B．expand
C．shrink           D．solve
35．By writing the article，the author wants toB．
A．advise us to form good habits
B．tell us we should study hard and don't fear challenges
C．learn from the poor students
D．encourage us to save money in every aspect in our life．
