3．How many times have you laughed today？Have you ever wondered what makes you laugh？In the whole animal kingdom，only we humans are capable （有能力的） of laughter．On average，we laugh about 17times a day．
Laughter is a spontaneous reaction of the body to some-thing funny or pleasant．Have you noticed that when you laugh，many parts of your body respond （反應(yīng)）？Your face changes expression，your breathing changes，and muscles throughout your body are affected．
An interesting story dates back to 1962．In a school in Tanganyika，in Africa，a group of schoolgirls started laughing uncontrollably over a joke．This laughter became epidemic （傳染的），jumping from one person to the next，spreading across communities，and lasting for six months!So strong was the"laughter epidemic"that schools had to shut down till it ended．
How we laugh remains a mystery．Whatever the reasons，laughter，as the saying goes，"is the best medicine．"In fact，science has proven that being happy and laughing can not only keep us healthy and fit but help deal with serious illnesses．
Laughing exercises all the important muscles，and keeps you fit．People have started forming laughter clubs that use laughter to treat illnesses．They meet at specific places at fixed times and laugh together．Laughter spreads，so this exercise works best in groups； once one person starts laughing，others automatically （自動(dòng)地） join in．
32．The underlined word"spontaneous"in the second paragraph probably means"B"．
A．perfect            
B．natural          
C．strange           
D．terrible
33．People have formed laughter clubs toD．
A．kill time          
B．relax         
C．meet others        
D．keep healthy

B．How Laughter Helps Cure Disease
C．Laughter，What It Is，and What It Can Do
D．The Relationship Between Laughter and Health
35．The passage is probably taken from a（n）A．
A．health magazine        
B．a(chǎn)d          
C．novel

8．"YOUR password has expired （過期），"a message said on my screen，with instructions for changing it．Coming up with a new code doesn't seem like a big deal，unless you work at my company，where we have to change it monthly，using at least one uppercase （大寫的） character，one lowercase character，one symbol，and one number．Oh，the whole password can't be fewer than eight characters．And I can't use any of the same passwords I've used in the past three months．
Suddenly I was furious．What didn't make it any better was that I was deeply depressed after my recent divorce．Disbelief about what she had done to me was all I thought about every day．
I remembered a tip I'd heard from my former boss．He'd said："I'm going to use a password to change my life．"
I couldn't focus on getting things done in my current mood．There were clear signs of what I needed to do to get control of my life again．
My password became the sign．My password reminded me that I shouldn't let myself be a victim of my recent breakup and that I was strong enough to do something about it．
I made my password Forgive@h3r．
I had to type this several times a day．The simple action changed the way I looked at my ex-wife．That constant reminder led me to accept the way things had happened and find a new way of dealing with my depression．As the month wore on，I felt a slow healing begin to happen．By the time my server asked me to reset my password the following month，I felt free．
One month later，my dear Exchange server asked me yet again to reset my password．I thought about the next thing that I had to get done．
My password became Quit@smoking4ever．
I quit smoking overnight．
This password was a painful one to type during that month，but doing it helped me to yell at myself in my mind as I typed that statement．It motivated me to follow my monthly goal．
One month later，my password became Save4trip@thailand．
Guess where I went three months later：Thailand．
Seeing how these reminders helped to achieve my goals kept me motivated and excited．While it's sometimes difficult to come up with your next goal，keeping at it brings great results．

41．Which of the following passwords fits the company's requirements？D
A．Seeme@like
B．Dream4future
C．Visit﹩me
D．Stay@4ever
42．What does the underlined word"furious"mean in the second paragraph？B
A．excited
B．a(chǎn)ngry
C．tolerate
D．pleased
43．Why couldn't the author focus on doing things？C
A．Because he couldn't come up with a new password．
B．Because he always forgot his password．
C．Because he was in low spirits due to his divorce．
D．Because his wife stole his password before their breakup．
44．What happened to the author after he had used his password to change his life？A
A．He finally overcame his depression and forgave his ex-wife．
B．He started smoking to heal his broken heart．
C．He quit his job and went traveling around the world．
D．He became furious about his passwords getting longer and longer．
45．What message does the author intend to convey through his story？D
A．Never let yourself be a victim of others'faults．
B．Be patient with the healing process for any pain．
C．Constant reminders can be positive as well as negative．
D．Setting yourself a goal and keeping at it can bring great results．

8．What did you eat for lunch today？Did you choose this dish because it was healthy，cheap or because it was just very tasty？Are you a particular eater or an adventurous diner？
I love exploring trends in food．‘Fusion（融合） cuisine'is not for everybody．My Italian grandmother would turn her nose up in disgust at the thought of tandoori pizza with mango topping but this marriage of tastes is perfectly fine in the 21st century．Chef and food writer Ching-He Huang，who presented a series of Chinese Food for the BBC，is a fan of the movement．She says："Fusion has been happening for centuries，for as long as people have travelled，but with the Internet，and global travel，the exchange of ideas makes the process much faster．"
Wolfgang Puck is seen by many as one of the chefs who made‘fusion'elegant．He got his experience in this aspect in his native Vienna and made a name for himself when he opened his own restaurant in Los Angeles in the 1970s．This European dug into Asian cuisine and became one of the first in a long line of distinguished chefs．He said in an interview with the Wall Street Journal that initially he got negative responses from traditional American-Chinese restaurant owners but he is not bitter．"I believe authenticity is about evolution，not repeating your grandmoter's recipe．"he explains．"Cooking is like painting or writing a song．Just as there are only so many notes or colours．there are only so many flavours-it's how you combine them that sets you apart．"
My granny's cup of tea would be the Slow Food Movement．Founded by her countryman Carlo Petrini in the 1980s and still going strong，it seeks to preserve regional cuisine and the use of ingredients that are grown locally．Petrini wants to see farmers connected more directly with consumers．
All these trends give us food for thought．We might be wasting an exciting opportunity to wake up our taste buds when we swallow a sandwich at our desks．Tomorrow，why not find an exotic restaurant and enjoy a feast？You dress trendy so eat trendy!
28．Fusion cuisine isD．
A．a(chǎn) BBC cooking programme      
B．a(chǎn) balanced diet rich in nutrition
C．a(chǎn) new trend of global travelling

12．There is an island called Kitava，way out there in the Pacific Ocean，in the Milne Bay Province of Papua New Guinea．It is one of the four main Trobriand Islands with a total population of 12，000 native residents．Rich with culture，surrounded on all sides by clear blue water and abundant rainforest，Kitava is as apealing as it is remote．But it has more to offer than good views．
As Byrdie reports，Kitava is also home to a people whose diet and nutritional habits remain healthy，untouched by Western influence．A lifetime of not knowing the sweet，sweet sensation of the salt from a potato chip hitting the roof of your mouth has done more than just spare Kitavans from illnesses like diabetes and cardiovascular disease； it's also given them a lifetime of smooth，acne（痤瘡）-free skin．
In a study of l'，200 subjects-including 300 teens and young adults-conducted by a team led by medical doctor and professor Steffan Lindeberg over 843 days，not one breakout was reported．They also found that genetics played little to no role in the results．
In fact，the average Kitavan diet is fairly common．It's simple，with no"miracle fruit"or"rare nut"to speak of，and Kitavans don't even exercise much．That diet consists mainly of yams（ 山荮），sweet potatoes，and taro （芋頭），local fruits （namely coconut），fish，and vegetables．
But if you're already pulling out your suitcases and drafting a resignation letter to your boss，you might want to slow your step．For one thing，the closest airport is over 700 miles away from the island，so good luck getting there．And consider this：do you really want to move somewhere where you'll be the only person with acne until the diet kicks in？I don't think so．

28．Which are the contributing factors of attracting visitors to the island？B
a．Rich culture．b．Clean white sand     c．Thick rainforest   
d．Clear blue water  e．Romote tribes
A．a(chǎn)bc       B．a(chǎn)cd         C．bcd        D．a(chǎn)de
29．What accounts for the fact that the Kitavans own good skin？D
A．They don't like eating salt．．
B．They enjoy varieties of rare fruits．
C．They are sick of exercising．．
D．They follow simple but healthy diet．
30．What is unlikely to be included in the Kitavans'diet？C．
A．Taro            B．Fish              C．Potato chips        D．Coconut
31．What can we learn from the last paragraph？A
A．Think twice before moving to Kitava．
B．Don't hesitate to quit your job and move there．
C．One can reach Kitava by plane without difficulty．
D．Anyone will own acne-free skin on stepping on Kitava．
