4.Christian Eijkman,a Dutch doctor,left the Netherlands for the island of Java.Many people on the island had a disease called beriberi(脚气病).He was going there to try and find a cure.

At first,Eijkman thought some kind of germ (细菌) caused beriberi.He raised some chickens.He didn't eat them,but made experiments on them.The local people were quite surprised at that.One day he noticed that his chickens became sick when they were fed the food most Javanese ate-refined white rice (精炼米).When he fed them with unrefined rice,also known as brown rice,they recovered.Eijkman realized that he had made an important discovery-that some things in food could prevent disease.These things were named vitamins (维生素).The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins.Later,other diseases were also found to be caused by the lack of vitamins in a person's food.

Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat.If they don't,they can also take vitamin pills.

14.You are busy filling out the application form for a position you really need; lets assume you once actually completed a couple of years of college work or even that you completed your degree.Isn't it tempting to lie just a little,to claim on the form that your diploma (文凭)represents a Harvard degree?Or that you finished an extra couple of years back at State University?

More and more people are turning to an utter deception (欺骗)like this to land their first job or to move ahead in their careers.For personnel officers'like most Americans'value degrees from famous schools.A job applicant may have a good education anyway,but he or she assumes that chances of being hired are better with a diploma from a well-known university.Registrars(学籍管 理员)at most well-known colleges say that they deal with dishonest claims like these at the rate of about one per week.

Personnel officers do check up on degrees listed on application forms.If it turns out that an applicant is lying,most colleges are unwilling to accuse the applicant directly.One Ivy League school refers to them as"special cases."One well-known West Coast school,in perhaps the most delicate phrase of all,says these claims are made by"no such people."

To avoid complete lies,some job seekers claim that they"attended"or"were associated with"a college or university.After careful checking,a personnel officer may discover that"attending"means being dismissed after one semester.It may be that"being associated with"a college means that the job~seeker visited his younger brother for a football weekend.One school that keeps records of false claims says that the practice dates back at least to the turn of the century that's when they began keeping records,anyhow.

If you don't want to lie or even stretch the truth,there are companies that will sell you a fake diploma.One company,with offices in New York and on the West Coast,will put your name on a diploma from any number of nonexistent colleges.The price begins at around twenty dollars for a diploma from"Smoot State University."The prices increase rapidly for a degree from the"University of Purdue."As there is no Smoot State and the real school in Indiana is properly called Purdue University,the prices seem rather high for one sheet of paper.

68.The writer mainly wants to tell us thatC,

A.college degrees can now be purchased easily

B.nowadays it is very hard for people to find jobs

C.lying about college degrees is becoming a widespread problem

D.employers are no longer interested in applicants'actual performances

69.As used in the first line of the second paragraph,the word"utter"meansA

A.thorough B.careful C.incomplete D.spoken

70.Once finding applicants with false diplomas,most colleges would.C

A.keep the records of them

B.drive the them out of college

C.avoid direct conflicts with them

D.accuse them of such behaviors

71•We can Ieam from the passage thatA.

A.US employers value their job applicants with a degree from top universities

B.University of Purdue and Purdue University are the same school

C.people with fake diplomas can get their first jobs in US easily

D.people pay the same price for a fake diploma from different universities.

15.Linden Wolbert on What It's Like to Be a Real-Life Mermaid

Many little girls dream of swimming with or meeting a mermaid,but Linden Wolbert actually left her day job to become one.

"I have always been attracted to water,"she said in an interview."Not just because of the animals that live in it,but because I feel so comfortable swimming in it.I just was always a swimmer and loved to be in the water."

After three years of working 9 to 5 as a residence director for Emerson College,"I was just daydreaming over every single lunch break about being in the water and among the fish,"she said.As an experienced swimmer and scuba diver,Wolbert also loves free diving,in which you dive as deep as you can and swim back up to the surface in a single breath-perfect training for a professional life as a mermaid.She made the change from office worker to mermaid in 2005 and hasn't looked back since.

Though Wolbert,32,loved movies like"The Little Mermaid"and"Splash"as a kid,she says that she really spent most of her time watching the wildlife documentary(纪录片)."My goal was to become an underwater wildlife documentary filmmaker like Jacques Cousteau,"she says-and she also works in the Los Angeles area as an advisor on underwater photo and video shoots.When special-effects artist Allan Holt asked her to help him with an underwater music video a few years ago,she mentioned that she'd always wanted an artificial mermaid tail but didn't know where to find one.

With the help of advanced technology,Holt ended up making a 35-pound,6-foot-long tail for her,sealing a fish tail inside high-quality rubber,hand-making the scales(鱼鳞),and creating a detailed copy of Wolbert's body.It took seven months to complete and cost approximately $15,000.

She also produces and stars in her own internet show,"The Mermaid Minute",in which she teaches kids about the oceans and the creatures that live in them.

"I am a smart science mermaid."she said."And working with children is my favorite."

49.Why did Linden become a mermaid?D

A.She wanted to do scientific research

B.She felt stressed in her office work.

C.She enjoyed feeding sea animals

D.She liked water and swimming.

50.What MOST helped Linden become a mermaid?B

A.Her love for mermaid films

B.Her experience in freediving.

C.Her knowledge of life under the sea

D.Her desire to be an underwater filmmaker.

51.Which of the following words best describes Linden's mermaid tail?A

A.High-tech.B.Real.C.Colorful.D.Inexpensive.

52.As a mermaid,what's the most valuable thing that Linden gives kids?D

12.Count Me Out

Call me old-fashioned.Call me old.Call me what you want,but refuse to become part of this new Internet world.

I do not possess a computer at home or at the office.Actually,I stopped going to an office 35years ago,when all communications were done with a pen,a typewriter,or,if the matter was of world-shaking importance,over the telephone.Likewise,if you like something advertised in a newspaper or magazine,you visited the shop selling it at the given address,or you phoned,the number shown.Then you spoke to the fellow and asked for further details.

Tell me what you think of the following ad that appeared the other day in the newspaper.It was for a cure for cancer and this is what it said:"Awareness is the key.Visit spfulford.com at the awareness site."There was no address or telephone number for the site.So what do unfortunate people without a computer do it they are seeking a cure for their illness?

There are,I am told,certain advantages in having access to the Internet.You can,for example,send love messages across the world or even get married to someone that you meet online.This bit doesn't interest me; I have been happily married for 60years.There are,of course,other activities for Internet users besides finding love.They can pay bills,order groceries,or discuss with their doctors.

And this is by no means all.More amazing things are yet to come in the near future.I read a newspaper report recently that quoted Stephen Hawking,an important British scientist."The complexity of a computer as it exists today is probably less than the brain of an earthworm,"he said."But,as technology advances,computers will become more complex,and a time may come when the Internet may develop‘consciousness.'In other words,the Internet will be able to think,have feelings,and may well be able to act on its own."

If Professor Hawking is right,I may change my attitude about conjurers.As I grow older each day,I would like one of those that not only thinks for me but also accepts responsibilities for all my mistakes.

60.What's the meaning of the title"Count Me Out"?D

A.Get me out of the Internet world.

B.Computers are trying to take control of life.

C.Modern technology pushes old people away.

D.Do not expect me to be a supporter of the Internet.

61.According to Paragraph 2,the author thinks computers areA.

A.unnecessary  B.convenient  C.expensive  D.advanced

62.What might the author like about the future computer?A

A.Taking blames.

B.Curing illnesses.

C.Delivering messages.

D.Responding to emotions.

13.I can still remember the first day when I met my best friend.She had just moved into the neighborhood and her grandmother brought her down to meet me.I hid behind my mother and she hid behind her grandmother,scared to look at each other.

Soon,we lost the shyness and started playing with each other,bike riding to each other's house and having sleepovers.In 7th grade she was going through family problems.However,every summer we would always sit at each other's house and watch movies on TV and talk about all the boys we liked.

It was last year when I noticed the problem.She suffered from clinical depression(抑郁症),and had to go to a hospital during the day.I was very sorry for her at first.But with the late night calls,and meeting each other halfway up the street at midnight,we still stayed in touch.I wanted to be there for her since her new best friend left her,and I knew I still cared about her like a sister.

Yesterday she came to me and said this."I never knew what a best friend was until you were the only person that would stop me from cutting myself; the only person that ever made me feel better about myself and my problems.You didn't know this but I was trying to kill myself that very night you called me and I was crying.I owe you so much,and you didn't even know you were helping me."

We both cried.And I guess a kind of lesson from my life so far is to never give up your friends.Even if they aren't as cool as others,or people think they are crazy,they need someone there.If you leave them,you will only be very sorry.So if friends need you,and you care for them,you should be always there for them.

41.Why did the two girls hide behind their family members when they first met?D

B.Because they didn't like each other.

14.I took the bus to work for many years.No one knew each other; the passengers all sat there sleepily in the morning.The bus was cheerless and silent.

One of the passengers was a small gray-haired man who took the bus to the center for senior citizens every morning.No one ever paid very much attention to him.

One July morning he said good morning to the driver and smiled.The driver nodded guardedly(戒备地).The rest of us were silent.

The next day,the old man boarded with a big smile and said in a loud voice:"A very good morning to you all!"Some of us looked up,amazed,and murmured"Good Morning"in reply.

The following weeks,our friend was dressed in a nice old suit and tie.His thin hair had been carefully combed.He said good morning to us every day and we gradually began to nod and talk to each other.

One morning he even had a bunch of wild flowers in his hand.The driver turned around smiling and asked:"Have you got yourself a girlfriend,Charlie?"We never got to know if his name really was"Charlie",but he nodded shyly and said yes.The other passengers whistled and clapped at him.Charlie waved the flowers before he sat down on his seat.

Every morning after that Charlie always brought flowers.Some passengers also brought flowers for him.The bus became a happy place.

Then,one morning,as autumn was closing in,Charlie wasn't waiting at his usual stop.When he wasn't there the next day and the day after that,we started wondering if he was sick or-hopefully-on holiday somewhere.

When we came nearer to the center for senior citizens,one of the passengers asked the driver to wait.We all held our breaths when he went to the door.

The old gentle man was fine,but one of his close friends had died over the weekend.How silent we were the rest of the way to work.

The next Monday Charlie was waiting at the stop,stooping (弯腰) a bit more,a little bit more gray,and without a tie.Inside the bus was silent.Even though no one had talked about it,all of us sat there silently,our eyes filled with tears and a bunch of wild flowers in our hands.

56.From the passage,we can infer thatC

A.people always cared about each other on the bus
