9.In colleges around the country,most students are also workers.
The reality of college can be pretty different from the images presented in movies and television.Instead of the students who wake up late,party all the time,and study only before exams,many colleges are full of students with pressing schedules of not just classes and activities,but real jobs,too.
This isn't a temporary phenomenon.The share of working students has been on the rise since the 1970s,and one-fifth of students work yearround.About one-quarter of those who work while attending school have both a full-courseload and a full-time job.The arrangement can help pay for tuition (学费) and living costs,obviously.And there's value in it beyond the direct cause:such jobs can also be critical for developing important professional and social skills that make it easier to land a job after graduation.With many employers looking for students with already-developed skill sets,on-the-job training while in college can be the best way to ensure a job later on.
But it's not all upside.Even full-time work may not completely cover the cost of tuition and living expenses.The study notes that if a student worked a full-time job at the federal minimum wage,they would earn just over 15,000each year,certainly not enough to pay for tuition,room,and board at many colleges without some serious financial aid.That means that though they're sacrificing time away from the classroom,many working students will still graduate with at least some debt.And working fulltime can reduce the chance that students will graduate at all,by cutting into the time available for studying and attending classes.
There is little reward for attending but not finishing college.Students who wind up leaving school because of difficulty in managing work and class are likely to find themselves stuck in some of the same jobs they might have gotten if they hadn't gone at all.The difficulty of working too much while in school can create a cycle that pushes students further into debt without receiving any of the financial or career benefits.
63.According to the passage,the reality of college students is thatD.
A.they throw parties a lot
B.they stay up late every night
C.they pay no attention to exams
D.they work besides attending classes
64.What is the indirect cause of an increasing number of working students?C
A.The need of developing social networks.
B.The lack of summer jobs for young adults.
C.The chance of finding a job after graduation.
D.The expenses of high tuition and living costs.
65.We can learn from the passage thatD.
A.working students are more likely to finish college
B.students can cover their college expenses through working
C.students receive a huge reward for managing work and class
D.dropping out of college may not help students get career benefits
66.What is the best title for the passage?B
A.The Difficulties of Landing a Job
B.The Struggle of Work-School Balance
C.The Reward of Working While Studying
D.The Images of Working College Students.

17.A tailgate party is a social event held on and around the open tailgate of a vehicle.Tailgating,which originated in the United States,often involves consuming alcoholic drinks and frilling food.Tailgate parties usually occur in the parking lots at stadiums,before and occasionally after games and concerts.People attending such a party are said to be tailgating.Many people participate even if their vehicles do not have tailgates.
The idea for eating out of the back of a car may have started in 1866with Charles Goodnight,a Texas farmer.He noticed that the cowboys he employed needed a way to eat on the road,so he transformed a U.S.Army wagon(马车) into a mobile kitchen.There,hungry workers could eat,relax,and socialize after a long day of working.
Nowadays,people tailgate for lots of reasons,everything from college football games to Jimmy Buffet concerts.In schools and communities,some athletic departments,coaches and parents of student athletes rely on post-game tailgating parties to build community and support for their program and team.
What people consider essentials(必备)for tailgating spreads isn't the same across the country.Different areas of the country have their own favorite foods for tailgating.While foods like burgers and chips may be common everywhere,some areas have specialties.For instance,those in Louisiana may consider jambalaya a tailgating must,while those in the Midwest simply can't go without brats.And the West Coast?Don't be surprised to see grilled fish or pasta.While dishes may differ from area to area,one thing is the same across the country:beer.
24.Why did Charles Goodnight invent a mobile kitchen?B
A.To show off his cooking skills            
B.To build a canteen
C.To celebrate the army's victory           
D.To attract more cowboys
25.What can we learn about tailgate parties?C
A.They are usually held before concerts
B.They are mainly held for cowboys
C.They are also occasions to make friends
D.They are meant for football teams
26.What do people think a must for all tailgate parties?A
A.Beer             B.Sports            C.Music          D.Vehicles with tailgates
27.What is the last paragraph mainly about?C
A.The spread of tailgating
B.The popularity of jambalaya
C.Favorite foods on tailgate parties
D.Necessary equipment for tailgating.

7.When I came home to London at the end of my first term at university in December 1968,I was flat broke,and more broke because it was Christmas,so I went to an employment agency for a job.
"Would you like to work for the Beatles?"they asked.
Don't you have anything better?"I asked.
Fifteen minutes later I got the job.Wen I asked why they accepted me when millions would have done the job for free,the answer was"That's just the proble."Yes.I owed the job to the fact that I was not a crazy fan.
But of course I was a fan.It was difficult not to be.I worked over the winter holiday in 1968 and also during Easter 1969.I had to take a taxi in the days to deliver papers sealed in envelopes to the Beatles'house.I took the envelopes to the address,handed them over to whoever answered the door and lift.Who would entrust(委托)such papers to an unknown student today-the envelopes would be opened and the contents of the papers copied and sold to the Press,I t never opccurred to me to do that.Much has been lost in 40 years!
I am always asked how many autographs(签名) I collected,and the answer is none.How uncool would it have been to ask for an autograph?Far better just to hear the Beatles's greets--"Hi,boy."How's it goping?"
More than 40 years later,this remains the best job I have ever had.It met my immediate material need and provides a memory that can be my life treasure.For a child of the 60s,this was its peak.If some details of the memory are not so fresh,it's because they weren't important then.At 19,you take man you things that happen for granted.At 61,they become gold dust.If I had known that then,I would have kept a diary.

11.The way people hold to the belief that a fun-filled,pain-free life equals happiness actually reduces their chances of ever attaining real happiness.If fun and pleasure are equal to happiness then pain must be equal to unhappiness.But in fact,the opposite is true:more often than not things that lead to happiness involve some pain.
As a result,many people avoid the very attempts that are the source of true happiness.They fear the pain inevitably brought by such things as marriage,raising children,professional achievement,religious commitment,self improvement.
Ask a bachelor (单身汉)why he resists marriage even though he finds dating to be less and less satisfying.If he is honest he will tell you that he is afraid of making a commitment.For commitment is in fact quite painful.The single life is filled with fun,adventure,excitement.Marriage has such moments,but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night's sleep or a three-day vacation.I don't know any parent who would choose the word fun to describe raising children.But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations.It liberates time:now we can devote more hours to activities that can genuinely increase our happiness.It liberates money:buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless.And it liberates us from envy:we now understand that all those who are always having so much fun actually may not be happy at all.

71.According to the author,a bachelor resists marriage chiefly becauseC.
    A.he finds more fun in dating than in marriage
    B.he believes that life will be more cheerful if he remains single
    C.he is reluctant to take on family responsibilities
    D.he fears it will put an end to all his fun adventure and excitement
72.Raising children,in the author's opinion,isD.
    A.a moral duty                         B.a thankless job
    C.a source of inevitable pain          D.a rewarding task
73.From the last paragraph,we learn that envy sometimes stems fromB.
    A.hatred           B.misunderstanding          C.prejudice       D.ignorance
74.To understand what true happiness is one mustA.
    A.be able to distinguish happiness from fun
    B.make every effort to liberate oneself from pain
    C.put up with pain under all circumstances
    D.have as much run as possible during one's lifetime
75.What is the author trying to tell us?C
    A.It is important to make commitments.
    B.One must know how to attain happiness.
    C.Happiness often goes hand in hand with pain
    D.It is pain that leads to happiness.
