8．There is an English saying："Laughter is the best medicine．"Until recently，few people took the saying very seriously．Now however，doctors have begun to study laughter and the effects it has on the human body．They have found facts that laughter really can improve people's health．
Tests were carried out to study the effects of laughter on the body．People watched funny films while doctors checked their heart rate，blood pressure，breathing and muscles．It was found that laughter has similar effects to physical exercise．It increases blood pressure，the heart rate and the rate of breathing； it also works several groups of muscles in the face，the stomach，and even the feet．If laughter exercises the body，it must be beneficial．
Other tests have shown that laughter appears to be able to reducing the effect of pain on the body．In one experiment doctors produce pain on the body．In one experiment doctors produce pain in groups of students who listened to different radio programs．The group which tolerated（忍受） the pain for the longest time was the groups which listened to a funny program．The reason why laughter can reduce pain seems to be that it helps to produce endorphins in the brain．These are natural chemicals which diminish both stress and pain．
There is also some fact to suggest that laughter helps the body's immune system，that is，the system which fights infection．In an experiment，one group of students watched a funny video while another group of students served as the control group----in other words，a group with which to compare the first group．Doctors checked the blood of the students in both groups and found that the people in the group that watch the video had an increase in the activity of their white blood cells，that is，the cells which fight infection．
As a result of these discoveries，some doctors and psychiatrists in the United States now hold laughter clinics，in which they try to improve their patients'condition by encouraging them to laugh．
They have found that even if their patients do not really feel like laughing，making them smile is enough to produce beneficial effects similar to those caused by laughter．

6．Guide dogs enjoy their work very much，and they get a lot of satisfaction from a job well done，but there is no room for typical dog fun during the work day．Games，treats and praise distract the dog from helping its handler navigate （指引方向） the course．Even when the handler doesn't need assistance，a guide dog on the job is trained to ignore distractions and keep still．This is because a guide dog must be able to come to handler's workplace or be in public places without creating a disturbance（干扰）．
When you see a guide dog on the job，it is extremely important that you recognize that it is at work．Petting or talking to the dog spreads its concentration，which weakens the handler's ability to get around in his or her surroundings．People are very impressed with guide dogs and so we have a natural inclination（倾向）to praise them，but the best thing you can do to help a guide dog is to leave it alone so that it can pay attention to its surroundings and maintain its focus on its handler．Guiding is very complicated，and it requires a dog's undivided attention．
When a guide dog gets home at the end of the day，however，it will play and soak up praise just like an ordinary pet．Guide dogs make the difference between work and play based on their lead harness（牵狗用的皮带）：When the harness is on，they must stay completely focused----when it comes off，it's play time．Guide dogs work very hard every day，but they lead extremely happy lives，full of lots of attention and stimulation．
Working as a guide dog requires good physical and mental shape，so guide dogs typically retire just before they enter old age．Retirement is usually at age 8 or 10； but some work for a little longer，and some guide dogs retire earlier if they're having trouble with the work．

5．The human body is designed to move．But modern lifestyles and office jobs rarely give us the chance to move around．As we know，we're while we're eating； we sit in the car and we sit while we watch TV．And many of us sit for many hours at work．
New research shows that sitting less than three hours a day might extend your life by two years．Peter Katzmarzyk，a scientist at the University of Louisiana in the southern United States，says that sitting is ubiquitous in our lives，meaning it is something we do all the time，everywhere．
However，Mr．Katzmarzyk says that does not mean you can sit for the rest of your waking hours．He also says you may exercise often，"We can't throw away physical activity．It's extremely important．We have 60years of research showing us that．"
Mr．Katzmarzyk and his colleagues are part of a new generation of researchers studying how sitting all day affects length of life．"Studies that have assessed the relationship between sitting and mortality（死亡率）or television viewing and mortality are very rare．There's only been a few of them，actually five or six now，in the last four or five years．"They found that cutting television time to less than two hours a day could add one-point four years to life．
Luckily，change is already coming to some offices，especially in the design of desks．A"standing desk"lets people stand while they work．Another new design is called the"treadmill desk．"A treadmill is an exercise machine that lets you walk in one place．Even some U．S．schools are beginning to experiment with desks that are part bicycle to keep children moving．That's one of the strategies that many companies are using now．
Mr．Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives．
28．The underlined word"ubiquitous"is closest in meaning toD．

B．Exercise is important and don't sit too long．
C．Watching TV is bad，but can broaden one's horizons．
D．Stopping watching TV is a necessary but hard task．
30．What does Mr．Katzmarzyk think of his study in Paragraph 4？A
A．It's a relatively new area of study．
B．It's a hot subject studied by experts．
C．It's a study that begins too late．
D．It's not ignored by many experts．
31．Why are the desks of all kinds designed for those who sit more？C

4．They may have text，email，Facebook and Twitter，but young people are still lonelier than any other age group．The Loneliness in New Zealand Report，published by Statistics New Zealand，shows under 30s are more likely to feel lonely than older people because loneliness decreases with age．Loneliness and poor mental health were strongly related across all ages．Young people were not as likely to feel lonely because of financial hardship，but among older people，lack of money was a significant influence on loneliness．Women were more likely to feel lonely than men．
Philip Walker，spokesman for the General Social Survey，said because it was relatively new it was hard to know whether loneliness among young people was a new trend．But overseas research has found that levels of loneliness in youth today are growing．
Mr．Walker said the finding needed more exploration，including looking at the role of technology and social media．"It could be that people's expectations of connection have gone up，so we expect increased levels of connection，"he said．"While technology like cell phones could help young people stay connected，on the other hand for those who do get bullied（欺辱），especially bullied online，it's quite isolating．A lot of the time potentially it is a big contributor to loneliness．"
Figures from online dating website FindSomeone also confirmed more young people were looking for love．Manager Rick Davies，said younger dating hopefuls were the fastest growing group on the site．
Mr．Davies noted that since the report data was collected in 2010there had been huge growth in smart phones，which meant people were online even more．He believed online tools，such as Skype，could help people stay connected．"People can keep in touch with a wide range of friends from all over the world much more easily now．It's like you're sitting in your living room having a chat with them．"
Bemardine Reid，operations committee chairwoman for Samaritans，which operates a free helpline，said many of their calls came from people who were lonely．"It might be that they've got some problem，just like all the things people would normally talk to a friend about，but people who are alone lack those normal contacts．"
The Statistics New Zealand report also showed people who didn't have face-to-face contact with family and friends were more likely to feel lonely，as were those who lived alone．
12．Which of the following may Mr．Walker agree with？A
A．High technology may become a reason for loneliness．
B．People shouldn't use the Internet to get to know strangers．
C．It's hard for people to get enough connection online as expected．
D．Social media should play an important role in helping lonely people．
13．It can be inferred from the passage thatD．
A．FindSomeone is a website where you can find old friends
B．without technology，young people would not feel lonely

3．Like any good mother，when Karen found out that another baby was on the way，she did what she could not help her 3-year-old son，Michael，prepare for a new baby．Day after day，night after night，Michael sang to his mommy's tummy（肚子）．
Finally，Michael's little sister was born．But she was in a very serious condition．With sirens（警报）howling in the night，the ambulance rushed the baby to St．Mary's Hospital．The days inched by．The little girl became worse．The pediatric（儿科的） specialists told the parents to prepare for the worst．
Michael kept begging about singing to his sister，but kids are not allowed in pediatric department at St．Mary's Hospital．Karen made up her mind to take Michael to see his sister．She dressed him in an over-sized suit and marched him into the hospital．He looked like a walking laundry basket，but the head nurse recognized him as a child and shouted，"Get that kid out of here now!"Karen rose up strong，and the usually mild-mannered lady glared steel-eyed into the head nurse's face．"He is not leaving until he sings to his sister!"
Karen towed Michael to his sister's bedside．He gazed at the tiny baby losing the battle to live．And he began to sing．In the pure-hearted voice of 3-year-old，Michael sang："You are my sunshine，my only sunshine．You make me happy when skies are gray．"Instantly the baby girl responded．Her pulse rate became calm and steady．Her strained breathing became smoother．
"Keep on singing，Michael，""The other night，dear，as I lay sleeping，I dreamed I hold you in my arms．"Michael's little sister relaxed as healing rest seemed to sweep over her．"Keep on singing，Michael．"Tears conquered the face of the nurse．"You are my sunshine，my only sunshine．Please don't take my sunshine away．"

2．It's too soon to form a judgementabout this matter．

1．The movies just wouldn't be the same without the warm buttery taste of popcorn（爆米花）．Amazingly，this delicious treat started its life as a corn kernel（玉米粒）---and not from just any corn．Popcorn is a type of sweet corn that was originally grown in Mexico and spread to China，India and elsewhere．It is the only kind of corn that will pop．Today，most of the world's popcorn is grown in the United States．
Every popcorn kernel contains a tiny drop of water，surrounded by soft starch （淀粉）．When the popcorn is heated，the water turns into steam．This puts pressure on the surrounding hard kernel，forcing it to explode．The soft starch increases about 40times in size as the corn kernel turns itself inside out．
In the 1500s popcorn was an important food source for the Aztec Indians of central and southern Mexico．But it wasn't only food．It was also used in ceremonies or on red dresses and in necklaces．By the time the Europeans arrived in America，popcorn had spread through most of the American Indians．
Some early American settlers ate popcorn with cream and sugar for breakfast．But it wasn't until the late 1800s that popcorn became popular．The demand for popcorn increased and farmers began farming popcorn．The first mobile popping machine was invented in 1885，and popcorn was sold by street sellers much like hot dogs that are sold today．
During the Great Depression of the 1930s，the popcorn business still thrived as people could still afford it．Then in the 1950s television arrived and popcorn consumption decreased．People stayed home and stopped going to the theatre．But the link between movies and popcorn had already existed．Soon people began making popcorn at home on the stove and，later，microwave popcorn was introduced．
Today the movies have regained popularity and popcorn has once again become the favorite．
