19.The technique can lead to new ways to produce medicines,the researchers from the universities of Istanbul and Hawaii hope.
As part of an effort to improve treatments for life-threatening illnesses,a team of scientists have created rabbits that glow(发光) in the dark.
Their efforts produced two rabbits out of a litter of eight that went from being a normal,fluffy white to glowing green in the dark.The rabbits were born at the University of Istanbul as part of a collaboration(合作) between scientists from universities in Turkey and Hawaii.
The rabbits glow to show that a genetic manipulation technique can work efficiently,though the specific color is more cosmetic than scientific."The green is not important at all-it's just a marker to show the experiment can be done successfully,"said University of Hawaii associate professor Stefan Moisyadi.
To produce the glowing effect,researchers injected jellyfish DNA into a mother rabbit's embryos.Those altered embryos(胚胎).Those altered embryos were then inserted back into the mother.Similar experiments have resulted in glowing cockroaches and cats.
Eventually,the researchers hope the technique can lead to new ways to produce medicines,Moisyadi said."The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that
can be cheaply extracted,especially in countries that can't afford big pharma plants that make drugs,that usually cost $1bn to build,and be able to produce their own protein-based medication in animals,"Moisyadi said.
The rabbits are expected to have the same life span as their non-glowing counterparts(副本),but Moisyadi said he understands people can object to this kind of experimentation involving live animals.
"To the people against,I say:think about,what are the benefits and what are the injuries?"Moisyadi said."And if the benefits outweigh the injuries,let's go with the benefits."
Moisyadi,a native of Turkey who is now with the University of Hawaii,started developing the project in 2006,and researchers are now waiting to see if pregnant sheep produce similar results.

21.Moisyadi's attitude towards this kind of experiment isC.
A.doubtful.
B.indifferent.
C.supportive.
D.objective.
22.How did glowing effect produce?D
A.It was just the result of genetic selection.
B.Put a light into a mother rabbit's embryos.
C.Injected glowing cats DNA into a mother rabbit's embryos.
D.Injected Jellyfish DNA into a mother rabbit's embryos.
23.The final goal of this research isD.
A.To make animals cuter.
B.To make nights brighter.
C.To produce all kinds of glowing animals.
D.To produce beneficial molecules in animals'milk.
24.What can we learn according to the passage?C
A.The life span of glowing rabbits is much shorter than that of non-glowing ones.
B.The glowing rabbits were born only at the University pf Hawaii.
C.Scientists have created glowing cockroaches and cats before.
D.Three rabbits out of eight can glow in the experiment.

分析 经过研究人员的努力,土耳其和夏威夷大学的科学家们合作培育出能发光的两只兔子,研究人员希望该技术最终能产生生产药物的新方法.

10.A listener has written from China for advice about how to lose weight.Michael in Shanghai says he is 26and has battled with fatness for most of his life.
Weight problem is a complex condition.A doctor may advise taking medicine along with changing one's behaviors.Experts say that the most successful weight-loss plans include a well-balanced diet and exercise.People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use.To lose weight,you can reduce the number of calories you take in,increase the number you use,or both.
A recent study looked at four of the most popular dieting plans in the US.Researchers at Stanford University in California studied over 300overweight women,mostly in their thirties and forties.Each woman went on one of the four plans:Atkins,The Zone,Ornish or LEARN.The women attended diet classes and received written information about the food plans.
At the end of the year,the women on the Atkins diet had lost the most,more than four and one-half kilograms on average.They also did better on tests for cholesterol(胆固醇)levels and blood pressure.
Christopher Gardner,who led the study,says the Atkins diet may be more successful because of its simple message to eat less sugar.He says that there was not enough money to study men,but that men would probably have similar results.
Last week,another report based on thirty-one studies suggested that only a few people have long-term success with dieting.It says those who kept the weight off generally were the ones who exercised.

24.Which is a doctor's advice for weight loss?A
A.Taking medicine.
B.A well-balanced diet.
C.Exercise.
D.Balancing the number of calories.

A.Atkins.
B.The Zone.
C.Ornish.
D.LEARN.
26.What is the best way to lose weight from the last paragraph?C
A.To eat less.
B.To eat healthy food.
C.To exercise.
D.To be on diet.
27.What can we infer from the passage?D
A.Men will become overweight in their thirties and forties.
B.Women gain less weight than men.
C.Dieters will have low blood pressure.
D.Dieters may regain weight if they stop dieting.
14.Daniel was born in New Orleans,LA.,in 1962,slow to walk and talk,and short.He was the tiniest in his class,but he developed a warm,outgoing nature and was popular with his peers(同龄人).And he became skillful at sports.
Baseball gave him his earliest challenge.He was an excellent players in Little League.At graduation,the coach named Daniel the team's most valuable player.
His finest hour,though,came at a school science meeting.He entered an exhibit explaining how the circulatory system works.It was traditional,especially compared to(与…相比)the modern,computerized,blinking-light models entered by other students.My wife,Sara,felt embarrassed for him.
It turned out that the other kids had made their exhibits.As the judges went on their rounds,they found that these other kids couldn't answer their questions.Daniel answered every one.When the judges awarded the Albert Einstein Plague for the best exhibit,they gave it to him.
By the time Daniel left for college he stood six feet tall and weighed 170pounds.He was in superb condition,but he quit baseball for English literature.I was sorry that he would not develop his athletic talent,but proud that he had made such a satisfactory decision.
One day I told Daniel that the great failing in my life had been that I didn't take a year or two off to travel when I finished college.This is the best way,to my way of thinking,to broaden oneself.Once I had married and begun working,I found that the dream of living in another culture had disappeared.Daniel thought about this.After graduation,he worked as a waiter at college,a bike messenger and a house painter.With the money he earned,he had enough to go to Paris.
The night before he was to leave,I tossed in bed.I was trying to figure out something to say.Nothing came to mind.Maybe,I thought,it wasn't necessary to say anything.

C.He was good at basketball.
D.He got on well with his classmates.
29.Why was Daniel's mother upset about his exhibit?A
A.Because it was not to the taste of the judges.
B.Because it was computerized.

11.Every day we are exposed to images,videos,music and news.In this age of visual and aural hyper-stimulation,the medium of radio is making a great comeback.
"We're  at  the  beginning  of  a  golden  age  of  audio,"said  US-based podcaster Alex Blumberg in an article in The Sydney Morning Herald.In the last month alone,15 percent of US adults listened to a radio podcast (播客).These
statistics,released by Edison Research,show the successful evolution of traditional radio  broadcasts  to  the  present  day's  digital  podcast  format.The  term"podcast"was invented in 2004,but the trend only started gaining mainstream popularity in recent years.With the sharp increase in consumer demand for smart phones and tablets,podcast sales have jumped.
The appeal of the podcast partly lies in its multiplatform delivery and on-demand capabilities.You can listen during those extra minutes of the day when you're walking to the shops,waiting in a queue or riding the subway.Similar to television shows,podcasts are generally free to download and most offer new content every week.
Donna Jackson,22,Sydney University media graduate,listens to podcasts two or three times a week,via iTunes."I listen while I'm wandering around the house doing something else.It makes completing a boring task much more enjoyable…And it's an easy way of keeping in touch with what's going on in the rest of the world,"she said,"I mainly listen to BBC podcasts,but recently I've also been listening to This American Life and Serial.They have a special skill to really draw you in."
Unlike television and music,the audio format has the potential to create a deep impression on readers.Blumberg says this owes to the podcast's ability"to create close relationship and emotional connection."Sydney University undergraduate Hazel Proust,majoring in social work and arts,agrees."When you're listening,it feels as if the voice of the podcast's storyteller is talking directly to you.It's comforting,"said Proust.
It seems the age-old tradition of verbal storytelling is very much alive and well.

61.From the first two paragraphs,we can learn thatC.
A.traditional broadcast has come back
B.Americans love listening to the radio
C.podcasts have become very popular today

A.the influence of radios 
B.the advantage of podcasts
C.readers'impression on radios
D.people's reaction to the medium
