3.We regularly hear how important consumer spending is for the economy.The story goes like this:the more consumers spend,the more money circulates in the economy,which contributes to healthy job growth and profits.Keynes,a British economist,went as far as to say that individuals saving their money may actually be hurting the economy.Sounds troubling,doesn't it?
Fear not.You aren't actually hutting anyone else by saving money.Strong economic growth only comes from one place:savings.Not consumption.In fact,economic activity should not be mistaken for economic growth.For example,somebody takes their money,walks into a store,and purchases goods.The store increases its revenue.
But what happens to all of those goods and services that people have chosen not to consume by saving their money?Simple:Other people are allowed to consume them.Think of it this way:When you lend out your savings,you are actually saying,"Here,I am not going to consume right now,so why don't you?"Banks simply play the middleman:they collect lots of people's savings and then lend out lots of funds.
It takes an unbelievable amount of goods and services to construct a building.It takes food,shelter,and entertainment for all of the workers,as well.Without savings,it is quite impossible to finance such a construction.The coordination(协调)between savings and consumption is a necessary basis for sound economic growth.This coordination is also why consumer lending (say,to borrow a big sum of money to buy a car) is not productive,in a strict sense.It doesn't increase the net (净的) amount of wealth of an economy.Those savings could have been used to construct,say,factory equipment.
None of this means consumption and spending are"bad"things.They simply do not make us wealthier.Alter all,the final goal of production and savings is to consume.But to say that consumption is the engine of economic growth is to put the cart before the horse.Or,to rephrase:the consumption of wealth can never make you wealthier.Happier,perhaps.Wealthier,no.

63.What is the author's attitude towards Keynes'theory?D
A.Approving.
B.Reserved.
C.Uncertain.
D.Critical.
64.The underlined word"revenue"in Paragraph 2 is closest in meaning toD

65.The author holds the view thatD.
A.governments shall cut out banks as financial middleman
B.economic activity is equal to economic growth
C.consumer lending is the engine of economic growth
D.consumption is likely to lead to increased happiness

11.Well,parents,surprise!Lots of us are using Twitter and Facebook to find rides,and not just to school.It's awkward to call a friend and ask for a ride,and half the time they'll say,"Sorry,my car is full."But with Twitter,you just tweet#AshleysPoolParty and look for other people heading the same way.
It may sound risky,but many teens stay within their own social circles to find rides,and don't branch out beyond friends of friends when asking on Twitter.For me,I only rideshare with people I know,but to some young people,especially those taking longer trips,stranger danger is less of a concern.
The sharing economy got big during the recession(经济衰退).It allows people to access more goods and services using technology,while also allowing them to share cost.And that technology,for me,is what the car was for my mom,a gateway to more freedom.
According to the researchers at the University of Michigan,30 years ago,eight in ten American 18-year-olds had a driver's license.Today it's six in ten.So it's not that surprising that on my 16th birthday I wasn't rushing to get a license.All I wanted was an iPhone.Juliet Schor (Sociology professor at Boston College) knows people my age love being connected and for young people driving means they have to disconnect from their technology,and that's a negative.So if they could sit in the passenger side and still be connected,that's going to be a plus.
To me,another plus is ridesharing represents something much bigger than trying to save money.I see it as evidence that people still depend on each other.My generation shares their cars and apartments the way neighbors used to share cups of sugar.For the system to work,some of us still need our own cars.But until I get my own version of the silver Super Beetle,you can find me on Twitter.
66.The writer usually rideshares withB.
A.anyone heading the same way      B.people he knows
C.friends of friends               D.strangers of his age
67.Fewer young people choose to ride by themselves becauseD.
A.driving means offering free rides to others.
B.getting a driving license becomes more difficult.
C.driving one's own cars causes a negative impression.
D.driving makes them disconnected from technology.
68.We can conclude from the passage thatC
A.the writer rideshares just to save money
B.people under 18 are not allowed to drive
C.silver Super Beetle is the writer's favorite
D.the older generation had to fight for freedom
69.Which is the best title for the passage?A
A.Teens use Twitter to thumb rides.
B.Tips on reducing risks in ridesharing.
C.Car is no longer a gateway to freedom.
D.New generation knows how to save money.

18.These young men were a different kind of prisoner from those we had seen before.They-were brave,hostile(怀敌意的)and(1)     they would not take orders,and shouted
"Amandla!"at every opportunity.Their instinct was to confront(对抗)rather than cooperate.
The authorities②did not know how to handle them,and they turned the island upside down.
During the Rivonia Trial,I remarked to a security policeman that if the government did not reform itself,the freedom fighters who would take our place③would some-day make the
authorities miss us.That day had indeed come on Robben Island.
In these young men we saw the angry revolutionary spirit of the times.I had had some
warning.On a visit with Winnie a few months before,she had managed to tell me through our coded conversation that there was a rising class of discontented youths④who were violent and Africanist in beliefs.She said they were changing the nature of the struggle and that I should be aware of them.
The new prisoners were shocked by what they considered the inhuman conditions of the island,and said that they could not understand how we could live in such a way.We told them
that they should have seen the island in 1964.But hey were almost as sceptical of us as they were of the authorities.They chose to ignore our calls for discipline and thought our advice weak and unassertive(不果断).
It was obvious that they regarded us,the Rivonia Trialists⑤,as moderates⑥(温和派).
After so many years of being branded a radical(激进的)revolutionary,to be seen as a moderate was a novel and not altogether pleasant feeling.I knew that I could react in one of two ways:I could scold them for their disrespect or I could listen to what they were saying.I chose the latter.
'4hen some of these men,such as Strini Moodley of the South African Students'
Organization and Saths Cooper of the Black People's Convention,came into our section,I
(2)     
Shortly after their arrival on the island,the commanding officer came and asked me as a
favour to address the young men.He wanted me to tell them to behave themselves,to recognize the fact that they were in prison and to accept the discipline of prison life.I told him that I was not prepared to do that.Under the circumstances,they would have regarded me as a follower of the authorities.

B.the author's activities were strictly monitored
C.many were concerned about the influence these young men could make
D.these young men were willing to cooperate in face of difficulties
68.Sentences are missing in Blank (2)regarding the author's following reactions.Which of the  following reactions do you think he would have?A

8.A.How much sleep you need 
Sleep cycles & stages,lack of sleep.
Getting the hours you need to sleep consist of a series of distinct cycles and stages that restore and refresh your body and mind.
Even minimal sleep loss takes a toll on your mood,energy,efficiency and ability to handle stress.
B.Panic attacks and panic disorder
A panic attack is a sudden surge of overwhelming anxiety and fear.Left untreated,panic attacks can lead to panic disorder and other problems.They may even cause you to withdraw from normal activities.But panic is treatable and the sooner you seek helps,the better.
C.How to stop worrying
Continuous doubts and fears are paralyzing,not motivating or productive.Worrying can be,when it spurs you to take action,helpful to solve a problem.You need self-help strategies for anxiety relief.
D.Generalizes anxiety disorder
Everyone gets worried sometimes,but if you have a generalized anxiety disorder (GAD),worries and fears are so constant that they interfere with your ability to function and relax.
E.What you need to know about anti-anxiety drugs
Under guidance from a health professional,medication can relieve some of the symptoms of anxiety,but it requires non-drug treatments to produce lasting changes and continuing relief from anxiety.Medication doesn't cure the underlying problem and is usually not a long-term solution.Anxiety medications also come with side effects and safety concerns,including the risk of addiction.
F.Understanding stress
Modern life is full of hassles,deadlines,frustrations,and demands.For many people,stress is so commonplace that it has become a way of life.Stress isn't always bad.In small doses,it can help you perform under pressure and motivate you to do your best.But when you're constantly running in emergency mode,your mind and body pay the price.

15.The Republic of Vanuatu is an island nation located in the South Pacific Ocean.It was one of the poorest nations in the region.Within the last five years,however,it has become a hot spot for adventure travelers.In 2006 it was voted the happiest place on Earth.The reason is not that Vanuatu are the richest but that Vanuatu has white-sand islands,clear waters,the world's most accessible live volcano,great diving and food that grows faster than it can be picked.
With a population of about 221,000,Vanuatu has 113 languages,which is a result of 3,000 years of immigration from many Pacific countries.There are three official languages:English,French,and Bislama.Bislama developed from South Pacific English,a simplified language that traders and other foreigners used it to communicate with speakers of the many local languages.

13.The relationship between exercise and cancer has long both intrigued and puzzled oncologists and exercise physiologists.
Exercise is strongly associated with lowered risks for many types of cancer.At the same time,exercise involves biological stress,which typically leads to a short-term increase in inflammation(发炎)which can contribute to higher risks for many cancers.
Now,a new study in mice may offer some clues into the exercise-cancer paradox.It suggests that exercise may change how the immune system deals with cancer by boosting adrenaline(肾上腺素),certain immune cells and other chemicals that,together,can reduce the severity of cancer or fight it off altogether.
To try to better understand how exercise can both elevate inflammation and simultaneously protect the body against cancer,scientists at the University of Copenhagen in Denmark and other institutions decided to closely examine what happens inside mice at high risk for the disease.
So,for the new study,they began by gathering a group of adult lab mice.These animals generally like to run.
The scientists then implanted melanoma(黑素瘤) skin cancer cells into the mice before providing half of them with running wheels in their cages while the other animals remained sedentary.After four weeks,far fewer of the runners had developed full-blown melanoma than the sedentary mice and those that had been diagnosed with the disease showed fewer and smaller lesions.
They drew blood from both the exercising and sedentary animals and cells from any tumors in both groups.As expected,they found much higher levels of the hormone adrenaline in the blood of the exercising animals,especially right after they had been working out on the wheels but also at other times of the day.The body releases adrenaline in response to almost any type of stressful experience,including exercise.
They also found higher levels of interleukin-6in the blood of the runners.This is a substance that is released by working muscles and is believed to both increase and decrease inflammation in the body,depending on where and how it goes to work.
Perhaps most important,they found much higher numbers in the bloodstreams of runners than in the sedentary mice of a type of immune cell named natural killer cells that are known to be strong cancer fighters.
So the scientists repeated their original experiment multiple times,inducing cancer while allowing some mice to run and others to sit.In some of these follow-up experiments,the scientists injected the runners with a substance that blocked the production of adrenaline and gave sedentary animals large doses of added adrenaline.
What they now found was that when running mice could not produce adrenaline,they developed cancer at the same rate as the sedentary animals,while the sedentary animals that had been injected with extra adrenaline fought off their tumors better than other sitting mice.
More remarkably,the scientists determined that adrenaline seemed to be sending biochemical signals to some of the animals'IL-6cells,making them physiologically more alert,so that when a tumor began to develop in the affected animal,those IL-6cells in turn activated the natural killer cells in the bloodstream and actually directed them to the tumors,like minute guide fish.
With these results,"we show that voluntary wheel running in mice can reduce the growth of tumors,and we have identified an exercise-dependent mobilization of natural killer cells as the underlying cause of this protection,"said Pernille Hojman,a researcher at the University of Copenhagen who oversaw the new study.It perhaps provides one more incentive for us to get up and move.

63.The relationship between exercise and cancer has long puzzled oncologists and exercise physiologists becauseB
A.exercise is strongly associated with lowered risks for many types of cancer.
B.exercise can both elevate inflammation which can contribute to higher risks for many cancers and meanwhile protect the body against cancer.
C.exercise may change can reduce the severity of cancer or fight it off altogether.
