2．In the heart of Tokyo，a skyscraper，the Grand Prince Hotel Akasaka，is being demolished（拆除）．But there are no explosives in sight．Instead，all that can be seen is the roof slowly sinking as the building shrinks beneath it．
The Demolition is being carried out by the Taisei Corporation，which has developed what it claims is a cleaner and more environmentally friendly way to tear down high-rises．Called the Taisei Ecological Reproduction System，it works from the top down，breaking a building apart floor by floor．The once 140-metre tall hotel is now missing its top 30meters and by May it will disappear．The levels being pulled down are sealed within an enclosure that wraps around the building，while huge jacks（千斤顶）slowly lower the original roof down as floors are removed．Fully enclosing（围住）the demolition area reduces the dust emitted（散出）from the site compared with conventional methods，say Taisei's Hideki Ichihara．
Before the demolition begins，all non-structural elements of the building are removed by hand．Workers then take out beams（横梁）and concrete flooring．By recycling building materials and getting rid of heavy machinery that runs on fossil fuels（矿物燃料），Ichihara says，the process reduces carbon dioxide emissions by as much as 85percent．"In Japan alone there are 797skyscrapers over 100meters tall，around 150of which will be between 30and 40years old in the next decade，"says Ichihara．This has historically been the age when such buildings are arranged for demolition，but conventional methods are not suitable for such tall skyscrapers．Taisei and its competitors Kajima and Takenaka Corporations need to develop new demolition systems．Kajima's"cut and down"method removes floors from the ground up，while Takenaka's approach is almost the same as Taisei's．
After Tokyo was shaken by earthquakes in March 2011，the billionaire Akira Mori called for the country to stop building skyscrapers over 100meters high．Instead he suggested lower，wider-based structures should be built．Takuro Yoshida，a professor at Kogakuin University in Tokyo，argues that newer engineering techniques could keep buildings safely standing for longer periods．"The idea that buildings are rebuilt on a 30-to 40-year cycle is itself about 20years old，"he says，adding that the ecological benefits of demolition．

1．Absorbed in my to-do list of yesterday，I was walking into the office without paying any attention to my surroundings，when suddenly I turned the corner and there it was，
sitting on my chair．"Oh，my God，"I said surprisedly．"Zucchini（小胡瓜）"．"Isn't it that
nice？"said Rachel，my workmate．"Somebody left zucchini for everyone!"
Have you ever noticed how somebody actually gives you zucchini？At least，not in
the same way they give you corn or apples or tomatoes．I mean，if someone wants to give you a few fresh，juicy peaches off their tree，they walk right up and hand them to you．You will be pleased．It seems that they have confidence you will like their gift．But with zucchini，they left it and went away．No note．No calling card．I thought zucchini is the
abandoned orphan of the vegetable kingdom．
"Yeah，it's nice，"I said．"Who should we thank for this gift？""I don't know，"Rachel
said．"You know how it is with zucchini．"Of course I do．Nobody actually grows it．At least，not on purpose．It just grows like weeds．"So what are you going to do with yours？"I asked．"I will just do what I always do
with zucchini，"she said．This morning I stepped into my office area carefully，afraid of what might be there waiting for me．There was a piece of bread in a white box sitting on my desk．I picked it up．It smelled wonderful．I took a bite．It tasted wonderful．
"Who made the banana bread？"I asked．Rachel said，"It isn't banana bread．It's zucchini bread．"I stopped chewing．"This couldn't be zucchini．It's delicious!"I paused，and added，"But I dislike zucchini!""So do I，"Rachel admitted．"But a few years ago I found this great way to cook zucchini bread，and now I actually look forward to zucchini season．"I took another bite of the bread．I couldn't help wondering："How could anything so tasty come from something so distasteful？""It's a fact of life，"Rachel said．"You mix effort with creativity and you can turn almost anything around．"

20．Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight，according to scientists．The simple trick works because it stops diners eating for pleasure rather than for calories．It also triggers （引发） a part of the brain that is worried that unseen food may go bad．
An experiment by the University of Konstanz，in Germany，found that people who were blindfolded consumed nine percent fewer calories before they felt full，compared to those who could see．They also vastly overestimated how much they had eaten because they could not see how much was left on the plate．Blindfolded volunteers estimated they had eaten 88percent more than they actually had．
Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full．
In the experiment，50people were blindfolded and 40were allowed to see their food．All were told not to eat within two hours of the experiment．They were then given three 95g bowls of chocolate ice cream and invited to eat for 15minutes．Their bowls were taken away and the remaining ice-cream weighed，while the participants were quizzed on how much they thought they had eaten．
On average the group who could see ate 116g while the blindfolded groups ate 105g．However，the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers．They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see．
"The experienced pleasure of eating was significantly lower in the blindfolded group．Not seeing the food might have decreased the appetite．Sight plays an important role in the eating experience and in the overall dining experience．"
Previous studies have shown that the visual influence of food plays a large part in the taste．While restaurants that allow diners to eat in the dark state that it triggers other senses，in fact eating in darkness is likely to taste far milder than usual．

28．With the lights out，diners eat less partly becauseD．
A．they want to quickly finish their meals
B．they trust their feelings more than ever
C．they focus more on fun than the calories
D．they worry about the quality of the food
29．We can learn from the passage that the blindfolded groupB．
A．spent a much longer time eating the same food
B．believed they ate more than they really did
C．depended on past experiences to feel full
D．thought the food tasted better than usual
30．The last two paragraphs tell us thatA．
A．diners are likely to lose their appetite eating in darkness
B．senses rather than sight play an important role in the taste
C．findings of this experiment differ from the previous studies
D．restaurants benefit a lot from allowing diners to eat in the dark
31．The main purpose of the passage is toC．
A．provide statistics related to eating in the dark
B．offer reasons for people to eat in the dark areas
C．inform the readers of the result of an experiment
D．persuade the readers to lose weight in a new way．

19．Some people are like homing pigeons：Drop them off anywhere，and they'll find their way around．Other people，though，can't tell when they're holding a map upside down．Are the directionally challenged just bad learners？
Not all of your navigational （导航的）skills are learned．Research shows that your sense of direction is innate．An innate ability is something you are born with．Your brain has special navigational neurons-head-direction cells，place cells，and grid cells （网格细胞）-and they help program your inside compass when you're just a baby．
In 2010，scientists carried out an experiment to study baby rats'neural activity in their brains．Although the rats were newborns，the researchers discovered that their head-direction cells （which help them recognize the direction they're facing） were fully grown and developed．The rats，it seemed，were born with a sense of direction．And they hadn't even opened their eyes yet!
Humans，of course，are not rats．But the hippocampus-the brain area we use for navigation-is similar in most mammals．If the rat's compass develops this way，then it's likely that a human's compass does，too．
If we're born with a sense of direction，then why are some people so good at getting lost？The scientists found that the two other cells-place and grid cells-developed within the first month．Place cells are thought to help us form a map in our mind，while grid cells help us navigate new and unfamiliar places．The two cells work together，and that's where the trouble might be．
People who took part in a 2013study played a video game that required them to travel quickly between different places．Monitoring their brains，the scientists found that grid cells helped the gamers recognize where they were-even without landmarks．According to researcher Michael Kahana，differences in how grid cells work may help explain why some people have a better sense of direction than others．

32．What did the 2010research find？A
A．Rats have a natural ability to recognize directions．
B．Rats'hippocampus is different from that of humans．
C．Rats usually find their way without opening their eyes．

A．Place cells let us know how to read a map．
B．Grid cells help us reach the place we are going to．
C．They help us use a compass when we lose our way．

18．Can you imagine a car racer is so eco-friendly that its tyres are made from potatoes，its body is created from hemp （大麻） and rapeseed oil and it runs on fuel made from wheat and sugar beet？The one-seater racing car called Eco One is built by experts from Warwick University，who hope that Eco One will be adopted by the automotive industry．It is sold at﹩51，000．
Pollution-sensitive Dress
Don't be caught outside unaware of pollution levels in the air．The pollution-sensitive EPA Dress by Stephanie Sandstrom notices pollution in the air accordingly．This dress-which is actually quite pretty-looks like you pull it from the bottom of the dirty laundry pile when the air is dirty．It might protect your health by advising you to stay indoors for the day，but it won't do you any favor if you're meeting with clients．
Eco-friendly Umbrella
Traditional umbrellas come with a fixed surface．Although it is changeable，you cannot replace it easily．This eco-friendly design is more flexible．It is actually only an umbrella skeleton without any surface，which can be folded，so you can put anything such as newspapers，plastic bags or whatever you want to serve as the protecting surface．
Eco-friendly Moss （苔藓） Carpet
It is said that walking on fresh grass increases your blood circulation．The Moss Carpet，created by Nguyen La Chanh，looks at getting the grass to your feet．The mat includes ball moss，island moss and forest moss．The humidity （湿度） of the bathroom ensures that it grows well．And that's why you need to place it there and not anywhere else．

17．New research shows that sheep are clever
People often make jokes about how dull sheep are，but new research shows they may be cleverer than we think．Researchers at the University of Cambridge discovered that Welsh mountain sheep have brainpower that equals rodents （啮齿动物）．Tests found that the sheep can map the area they live in，and some may even be able to plan ahead．
Young fish prefer noisy neighbors
A new study has shown that young fish like to live on reefs with noisy neighbors!Researchers from the universities of Auckland and Bristol found that young fish looking for a home choose areas where other noisy fish live．The scientists produced all kinds of sounds which had been recorded in different natural environments．The young fish seemed to prefer the sounds of natural reefs，complete with noisy animals!The scientists compared the choice to a music fan wandering around at a music festival，choosing to set up a tent closest to the music they like best!
Butterflies are disappearing
A new study has shown that 17species of butterflies found in Europe have dropped by 70% in the last 20years．The information collected from 3，000sites across 15countries shows it may be caused by the loss of grasslands covered with flowers．You can encourage butterflies to come into your garden by planting flowers．

16．Although the United States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society Less than a tenth of the people are engaged in agriculture and forestry（林业），and most of the rest live in or around towns，small and large．Here the traditional picture is changing：every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more．Half the population now lives in some thirty metropolitan areas（1arge cities with their suburbs、of more than a million people each-a larger proportion than in Germany or England，let alone France．The statistics（统计）of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day．As the rush to live out of town continues．rural areas within reach of towns are gradually filled with houses，so that it is hard to say at what moment a piece of country becomes a suburb But more and more the typical American lives in a metropolitan rather than a small town environment．

15．Canada travel has become exciting as a number of lakes including"Great Lakes"in Canada make it attractive．In fact，Canada has more lakes than any other country which contains fresh water．In addition to lakes，Canada has a number of beaches as it has a long coastline on its north，east，and west．Travelers from around the world come in large numbers to enjoy sunbath at various beaches．
Niagara Falls lie on the border of Canada and the US．It is now popular for its beauty and is a valuable source of hydroelectric （水利发电的） power．Niagara Falls are most attractive during summer season when weather condition is charming and attractive．At the Canadian side，floodlights illuminate（照亮） both sides of the fall for several hours after dark and the whole scene becomes magnificent．
When traveling to Canada，travelers can enjoy doing shopping at Toronto which is considered a leading city．It symbolizes American culture and the spirit of independence．Migrants form European．Latin American，Asian and Caribbean races inhabit the place and make it a plural society．Ottawa，on the other hand，is the capital of Canada and center of political activities．
Vancouver is an enlightening city in Canada which was named after British Captain George Vancouver，who explored the area in the 1790s．The city is a leading industrial place in Canada．Another tourist attraction in Canada is the capital city of British Columbia，Victoria．The city is located on the southern tip of Vancouver Island．
Travel in Canada is being made easy as transportation facilities are of higher standard．Besides，very few people know that Canada is a high-paying country in terms of wages per hour．In addition to a popular tourist destination，Canada is an economic powerhouse of North America，particularly in agriculture products．Canada dairy industry exports（出口） milk products around the world．

14．Before I studied psychology，I used to think that people would laugh when funny things occurred．While I was right about that，I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke．When someone laughs at a joke，there will usually be more than one reason that makes him laugh-and the more reasons there are，the more powerful the joke will be．
I was attending a stand-up comedy show in Egypt，and when the man started to make fun of pedestrians crossing streets，everyone laughed their hearts out．The main reason those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly．The joke wasn't only funny，it also made the audience feel that they were right about being angry at those pedestrians．That is，people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got．
The better a joke makes a person feel，and the more it includes other psychological factors，the more the person will like it．For example，if you envy one of your friends，and someone tells a joke that is funny and，at the same time，makes your friend seem stupid，then you will probably laugh at it louder than if you weren't jealous of him．
In short，we don't laugh only when we hear something funny； we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke．I strongly discourage making fun of anyone or belittling someone to make someone else laugh．All I want to explain is that if your joke supports a person's emotions，he will certainly like it a lot．

32．What did the author find out after studying psychology？B
A．Only good jokes make people laugh
B．Many factors lead to people laughing．
C．Funny things can make people laugh
D．Laughter can make people healthy．
33．Why did the audience laugh loud at the pedestrians？D
A．They played a trick on the pedestrians．
B．The pedestrians behaved in a funny way．
C．They could feel the pedestrians'happiness．
D．Their emotion was approved of by the show．
34．What does the underlined word"belittling"probably mean？C
A．Annoy B．Blame C．Look down on D．Make up to
35．Which of the following best shows the structure of the passage？B

13．News reports warn us that the smog is expected to stay with us for a couple of months．Air quality is 10times worse than the World Health Organizaion's recommended levels．
