3.There are many reasons why fast food has become so popular all over the world.Some think that fast food is such a hugely profitable business-and obviously people enjoy eating it,but the popularity of fast food has increased as our lifestyles have changed over the years.
The social landscape has changed immeasurably since fast food appeared in the second half of (lie 20th century.Back then,mums mostly stayed at home with the kids.Dads went to work,and they all got a healthy home-cooked meal at the end of the day.The lifestyle was slower.In this age,some mums still stay at home,but many are out at work,and some are single parents.If both parents are at work,they are often content just to throw something into the oven or the microwave,because after a hard and busy day,people don't have the time to create a meal-or at least they think they don't.
Fast food isn't just limited to eating out and ordering in-it'S now so easy to get a ready meal from the supermarket.You can pick up any kind of food you can think of at most supermarkets-Chinese,Italian,Japanese or Thai.There are healthy lifestyle options,but most people,unless they are on a specific diet,tend to be seduced(引誘)by the images they see on the packaging,and the description of the meal inside.
The proportion of single households has increased greatly since fast food was invented.While families might make an effort to eat together and eat fresh,home-cooked food,the single lifestyle doesn't often allow for this.Many people who live alone simply can't be bothered to make a big effort to cook for themselves.Some don't know how to.
It will take a major shift in lifestyle and cooking ability to lessen the hold that junk food has over the population and replace it with good home cooking.

68.According to the author,what's the most probable reason why fast food has become so popular?A
A.People's lifestyles have changed.
B.Fast food makes people's life easy and convenient.
C.Businessmen can make big profit from selling fast food.
D.People don,t have the time to create a meal after a hard and busy day at work.
69.What was the life like in the first half of the 20th century?D
A.Fast food was somewhere to be found. B.People knew a little about fast food.
C.Things were cheap but life was hard. D.Most family ate a mum-cooked meal at home.
70.What might be the author's attitude towards the future of"home-cooked food"?B
A.Negative. B.Optimistic. C.Uncertain. D.Not mentioned.

15.The Israeli farmers who pioneered the revolutionary technology known as drip irrigation weren't trying to solve one of the world's most urgent problems.They were just trying to survive.They lived in the desert,and they didn't have enough water to grow their crops.
In its simplest form,it was little more than a pipe with holes in it.But behind each hole was a hi-tech dripper that let out just the right amount of water.Snaked along a row of crops so that the holes were positioned directly above the roots,the pipe could direct each precious drop of water directly to the plants,getting a bigger harvest while using a very small amount of the water.
Over time,the farmers improved upon the technology,perfecting the drippers that regulated the flow of water,and connecting the pipelines to computers that could determine exactly how much water each plant needed and when.
If the global population kept growing,the rest of the world would increasingly resemble their little community in the desert.So they began selling their irrigation systems in other parts of the world,eventually expanding to more than 110countries.Netafirm,the company says it's lifting people out of poverty and conserving water at a time when the importance of doing so has never been clearer.
The mass adoption of drip irrigation won't save the world by itself.To avoid the coming catastrophe,nearly everybody will,in some way,have to do more with less,perhaps through accepting and using other new technologies.Otherwise,it's going to get ugly.
32.Why is drip irrigation called"the revolutionary technology"?C
A.It saves the world all by itself.        
B.It is controlled by computers.
C.It makes irrigation more effective.    
D.It provides deserts with water.
33.What does"one of the world's most urgent problems"in Paragraph l refer to?A
A.lacking water.  
B.lacking labor.    
C.lacking food. 
D.lacking energy.
34.How does the drip irrigation help farmers with crops?B
A.By drilling holes on the pipes.    
B.By regulating water via drippers.
C.By snaking pipes along the crops.
D.By placing pipes just above roots.
35.Which of the following will be the best slogan for Netafirm to sell the irrigation systems?A
A.Less water;More harvest.    
B.New technology;New world.
C.More grain;Less starvation.
D.Water saving;World surviving.

14.In Silicon Valley,it's never too early to become an entrepreneur.Just ask 13-year-old David Moore.The eighth-grader has launched a company last October to develop low-cost machines to print Braille(布萊葉盲文).David built a Braille printer with a Lego Mindstorms EV3 kit as a school science fair project last year after he asked his parents a simple question:How do blind people read?"Google it,"they told him.David then did some online research and was shocked to learn that Braille printers cost at least 2,000-too expensive for most blind readers."I just thought that price should not be there.I know that there is a simpler way to do this,"said David,who demonstrated how his printer works at the kitchen table where he spent many late nights building it.David wants to improve the"Braigo"-a name that combines Braille and Lego-and develop a  Braille printer that costs around 350 and weighs just a few pounds,compared with current models that can weigh more than 20 pounds."My end goal would probably be having most of the blind people…using my Braille printer,"said David,who lives in the Silicon Valley suburb of Santa Clara,just minutes away from Intel headquarters.
     After the Braigo won numerous awards and enthusiastic support from the blind community,David started Braigo Labs last summer with an initial 35,000 investment from his dad."We as parents started to get involved more,thinking that he's on to something and this new way process has to continue,"said his father,Matthew Moore,an engineer who works for Intel.
Intel officials were so impressed with David's printer that in November they invested an undisclosed sum in his start-up.They believe he's the youngest entrepreneur to receive venture capital money invested in exchange for a financial stake in the company."He's solving a real problem,and he wants to go off and challenge an existing industry,"said Edward Ross,director of Inventor Platforms at Intel.Now the company is using the money to hire professional engineers and advisers to help design and build Braille printers based on David's ideas.It aims to have a prototype (樣機(jī)) ready for blind organizations to test this summer and have a Braigo printer on the market later this year.

66.Which of the followings is NOT the description of Braigo?C
A.The name"Braigo"comes from Braille and Lego.
B.The blind are in favor of the new type of printer.
C.It costs less money and weighs just a few pounds.

68.Which of the following is the correct order?A
①Intel officials invested money in David's start-up.
②David launched a company. 
③David got an initial 35,000 investment from his dad.
④David created a new Braille printer model called Braigo.

11.When e-mail first came into general use about twenty years ago,there was a lot of talk about the arrival of the paperless office.However,it seems that e-mail has yet to revolutionize office   communication.According to communications analyst Richard Metcalf,some offices have actually    seen an increase in paper as a result of e-mail."Information in the form of e-mal messages now floods our computer screens.These messages can be sent so quickly that memos(備忘錄) tend to be distributed in the hundreds.For those secretaries whose bosses ask them to print out all their e-mails and leave them in their in-trays,this means using up a great deal of paper every month,"Metcalf says.
Metcalf has found that because some e-mails get lost in cyberspace,important documents are     increasingly likely to be asked by clients(客戶)and colleagues to send all important documents both     by e-mail and by fax or"snail mail"-through the post.This highlights a further potential problem        with e-mail in today's offices-it is taking up time rather than saving it."With e-mail,communication is much easier,but there is also more room for misunderstandings,"says psychologist Dr David Lewis.Generally,much less care is taken with e-mails than with letters or faxes and the sender will probably print the document and reread it before putting it in an envelope or sending it by fax.
More worrying is still the increasing misuse of e mail for sending"flame-mail"-abusive or inappropriate e-mail messages,Recent research in several companies suggests that aggressive  communications like this are on the increase.E-mail has become the perfect medium for expressing  workplace dissatisfaction because it is so instant.
E-mail can also be a problem in other ways.Staffs all too often make the mistake of thinking that the contents fan e-mail,like things said over the phone,are private and not permanent.But it is not only possible for an employer to read all your e-mails,it is also perfectly legal.E-mail messages can be traced back to their origin for a period of at least two years,so you might want to rethink e-mailing your dissatisfaction about your too to your friends.The advice is to keep personal e-mails out of the office.
It goes without saying that e-mail exists to make Jife easier,and if used correctly,it is an invaluable tool for businesses of all sizes.But perhaps,for the time being,the fact that in the business world 70percent offal documents are still in paper form is not such a bad thing after all.

60.Why has the promise of the paperless office not come true in many offices?D
A.People write more memos than they used to.
B.Staff leave messages lying around their offices.
C.Many managers prefer to read their messages on paper.
D.Many secretaries keep paper copies of their bosses'e-mails.
61.What does Richard Metcalf say about e-mail in Paragraph 2?A
A.It is not an appropriate channel for sending important information.
B.It increases the amount of paperwork done in offices.
C.It is not popular with many secretaries.
D.It is a less efficient channel than fax.
62.Why should employees not use company e-mail systems for personal messages?B
A.Because company e-mail systems are not easy to use.
B.Because e-mail is not a private means ofcommunication.
C,Because they allow people to express their anger immediately.
D,Because the people the messages are sent to can't respond immediately.
63.What does the writer conclude about e-mail in the last paragraph?C
A.It has already made life a lot easier for many businesses.
B.It is not being used enough in business today.
C.It is really useful when people use it properly.
D.It will never replace written communication.

8.There are always minorities,either people or enterprises,that have absolute advantage(絕對優(yōu)勢)in a field; the majority apply their comparative advantage(相對優(yōu)勢) to professions where they do their best to be effective players.Based on comparative advantage,different divisions are formed as international trade and the globalized economy develop.
Oranges are flourishing in Florida in the United States,for example,shoes are made perfectly in Wenzhou of China,and people in both areas need oranges and shoes.In Wenzhou,one could try to create an artificial environment for orange trees of an international standard,and in Florida workers could be trained to make shoes as effectively as workers in Wenzhou using the same resources.However,the costs would be too high.The best solution,therefore,is to allow each location to specialize in its own product,producing enough to meet local needs and exporting the rest.As a result,people in both areas end up with lower cost and higher quality goods than if each tried to produce both.It is obvious that absolute advantage occurs in this process.
However,absolute advantage may not necessarily apply everywhere.For instance,I know a capable company boss,who is also an expert in private cars and very skillful at changing car oil,even more efficiently than a mechanic,But,almost every time he drives his car to a garage to have the oil changed by a mechanic since he believes he can use the time to do something more valuable.What he uses here is his comparative advantage rather than absolute advantage.
The same theory may also apply to individual careers.You may not be the best in a certain area,but still have a comparative advantage,which will not be reduced in relation to others'absolute advantage,and you can still find an advantaged position in which your disadvantage is smaller relative to others.
An ordinary talent can,therefore,achieve outstanding results by rightfully exploring his or her comparative advantage.In this sense,we may say that comparative advantage really works.

72.From the example about orange in Florida and shoes in Wenzhou,we can draw the conclusion thatC.
A.the field in Wenzhou can be improved to grow oranges.
B.Florida workers could be trained to make shoes.
C.we should fully use our absolute advantage in our advantaged field.
D.our comparative advantage is equal to our absolute one as to making fortunes.
73.Why doesn't the capable company boss change his car oil himself?C
A.The mechanic is more efficient than him.
B.He needn't do it by himself for his riches..
C.He would rather do something more valuable.
D.Changing oil is beyond his ability.
74.Which of the following is right according to paragraph 4.?D
A.You should use your absolute advantage in your work definitely.
B.You must work hard to improve your absolute advantage to be the best worker.
C.If other's absolute advantage is larger,your comparative advantage is smaller.
D.Sometimes you may still use your comparative advantage to find your advantaged position.
75.This article can be entitled"A".
A.The Advantage of Comparative Advantage.
B.The Advantage of Absolute Advantage
C.Absolute Advantage-the secret to make different talents
D.Comparative Advantage-the way to achieve outstanding results.

15.A wood fire can be handy when you're camping.You can roast marshmallows or stay warm,for example.Forest fires that rage out of control,however,are a big problem.
Wildfires cause hundreds of millions of dollars in damage every year.And the amount of destruction has grown over the last 2 decades,especially in the western United States.
To understand better why the northern Rocky Mountains region has been hit especially hard by wildfires,scientists from the University of Arizona in Tucson looked at weather,snow,and fire records from 1970 to 2003.^
Their study showed that,between 1987 and 2003,fires burned an area 6.5 times larger than the area burned between 1970 and 1986.The fire season also started earlier-,and its average length increased by 78 days.
Warmer spring and summer temperatures appear to be part of the explanation for this change.The average temperature in the study's more recent period was 0.871 higher than it was in the earlier period.And this trend is likely to continue.Experts predict that average summer temperatures may rise between 2¾and 5¾by the year 2050 in western North America.‘
Hie timing of snowmelt appears to be another cause of the fire boom.When snow melts early in the season,forests become drier through the summer and catch fire and burn more easily.Western snow packs now typically melt a week to a month earlier than they did 50 years ago,according to recent studies.
Some people have blamed the growing fire risk on policies that allow bush and branches to build up on forest floors.But clearing bush by itself won't help much if changes in climate are largely responsible for increasingly severe forest fires.
43.The main purpose of studying the records from 1970 to 2003 was toD.
A.find out solutions to forest fires
B.prevent wildfires from happening frequently-
C.know more about the climate changes in the past decades
D.find out the causes of wildfires in the northern Rocky Mountains region
44.Scientists fix>m the University of Arizona found out the following EXCEPTD
A.western snow packs melt earlier than they did 50 years ago
B.fires burned larger area between 1987.a(chǎn)nd 2003 than between 1970 and 1986

12.To help make up for sleep lost during marathon night flights,migrating(遷徙) birds take hundreds of power nap(小睡) during the day,each lasting a few seconds.
Every autumn,Swainson's thrushes(畫眉) fly up to 3,000miles from their breeding grounds in northern Canada and Alaska to winter in Central and South America.Come spring,the birds make the long trip back.
The birds fly mostly at night and often for long hours at a time,leaving little time for sleep.So to get through these tiresome periods,thrushes,during autumn and spring when the birds are normally migrating,change their sleep patterns,staying awake at night and resting during day.But instead of sleeping for a long period at a time,the birds took several naps a day,each one lasting only 9seconds on average.
The thrushes also mixed up their shut-eye sessions with two other forms of sleep.In one,called unilateral eye closure,or UEC,the birds rested one eye and one half of their brains while their other eye and half brain remained open and active,protecting them from danger.
The birds also occasionally slipped into another state,one that any college student who has ever been stuck in a boring lecture can relate to.Called drownsiness(睡意),this state is characterized by a partial shutting of both eyes that still allows for some visual processing.
"In terms of quality,drowsiness may be less useful than normal sleep,but it may also be safer."said Fuchs.
What's interesting is that even animals should make up for sleep loss.That a need for sleep cannot be lost even in these birds means the importance of sleep for many,if not all,animals,not to mention human.

29.What would be the best title for the text?D
A.Migrating Birds Travel for Long Hours
B.Migrating Need Help
C.How Birds Migrate during Autumn
D.Migrating Birds Take Many Daily Power Naps
30.According to the text,when having drowsiness,the thrushesC.
A.will rest one eye and the other active
B.will often sleep during day
C.will still be careful with the possible dangers
D.will not see anything in front of them
31.What can we learn from the text?A
A.Sleep is important for human being.
B.Animals need sleep to rest.
C.Migrating birds need sleep only during day.
D.College students often have drowsiness in fall.

13.A glass a day keeps obesity at bay.Alcohol has always been thought to cause weight gain because of its high sugar content,but new research suggests a glass a day could form part of a diet.Looking at past studies they found that,while heavy drinkers do put o weight,those who drink in moderation can actually lose weight.
A spokesman for the research team at Navarro University in Spain says,"Light to moderate alcohol intake,especially of wine,may be more likely to protect against,rather than promote,weight gain."The Inter national Scientific Forum on Alcohol reviewed the findings and agreed with most of the conclusions,particularly that current data do not clearly indicate if moderate drinking increases weight.
Boston University's Dr.Harvey Finkel found that the biologic mechanisms (生物學(xué)機(jī)制) relating alcohol to changes in body weight are not properly understood.His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes (糖尿。,which related to increasing obesity.Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.
The group says alcohol provides calories that are quickly absorbed into the body and are not stores in fat,and that this process could explain the differences in its effects from those of other foods.They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks,taking,into consideration drinking patterns and including the past tendency of participants to gain weight.
For now there is little evidence that consuming smfill to moderate amounts of alcohol on a regular basis increases one's risk of becoming obese.What's more,a study three years ago suggested that resveratrol,a compound present in grapes and red wine,destroy fat cells.
24.Who is the passage intended for?B
A.Those who produce wine.
B.Those who have drinking habit.
C.Those who sell alcohol      
D.Those who wish to quit drinking.
25.What does the phrase"in moderation"in the first paragraph refer to?C
A.Excitedly.B.Carefully.C.Properly.D.Frequently.
26.What can we learn from the passage?D
A.Current data clearly show that moderate drinking increase weight.
B.Resveratrol is proved to increase the risk of becoming fat.
C.The specific roles of different types of alcoholic drinks are very clear.
D.The research found moderate drinking has a strong protective effect.
27.What is most likely to be discussed in the paragraph that follows?D
A.How to do some easy experiments.
B.How to reduce the calories contained in wine.
C.How to make wine in a healthy way.
D.How to prove the finding mentioned above.
