8．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 36 equally 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（分離） 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（香味療法）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．
24．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．
25．The underlined part"abstain from"in Paragraph 3 probably meansA．
A．a(chǎn)void          B．practice             C．continue           D．try
26．What 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．
27．We 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．

7．Passenger pigeons once flew over much of the United States in unbelievable numbers．Written accounts from the 18th and 19th centuries described flocks（群） so large that they darkened the sky for hours．
It was calculated that when its population reached its highest point，there were more than 3billion passenger pigeons-a number equal to 24to 40percent of the total bird population in the United States，making it perhaps the most abundant bird in the world．Even as late as 1870when their numbers had already become smaller，a flock believed to be a mile wide and 320miles （about 515kilometers） long was seen near Cincinnati．
Sadly，the abundance of passenger pigeons may have been their undoing．Where the birds were most abundant，people believed there was an ever-lasting supply and killed them by the thousands．Commercial hunters attracted them to small clearings with grain，waited until pigeons had settled to feed，then threw large nets over them，taking hundreds at a time．The birds were shipped to large cities and sold in restaurants．
By the closing decades of the 19th century，the hardwood forests where passenger pigeons nested had been damaged by Americans'need for wood，which scattered （驅(qū)散） the flocks and forced the birds to go farther north，where cold temperatures and spring storms contributed to their decline．Soon the great flocks were gone，never to be seen again．
In 1897，the state of Michigan passed a law prohibiting the killing of passenger pigeons，but by then，no sizable flocks had been seen in the state for 10years．The last confirmed wild pigeon in the United States was shot by a boy in Pike County，Ohio，in 1900．For a time，a few birds survived under human care．The last of them，known affectionately as Martha，died at the Cincinnati Zoological Garden on September 1，1914．
24．In the 18th and early 19th centuries，passenger pigeonsD．
A．were the biggest bird in the world             
B．lived mainly in the south of America
C．did great harm to the natural environment       
D．were the largest bird population in the US
25．The underlined word"undoing"probably refers to the pigeons'B．
A．escape              
B．ruin
C．liberation            
D．evolution
26．What was the main reason for people to kill passenger pigeons？C
A．To seek pleasure．
B．To save other birds．
C．To make money．
D．To protect crops．
27．What can we infer about the law passed in Michigan？B
A．It was ignored by the public．
B．It was declared too late．
C．It was unfair．
D．It was strict．
