15.Every baby born a decade from now will have its genetic code (基因編碼) mapped at birth,the head of the worlds'leading genome sequencing (基因圖譜) company has predicted.
A complete DNA read-out for every newborn will be technically possible and affordable in less than five years,promising a revolution in healthcare,says Jay Flatley,the chief executive of Illumina.Only social and legal problems are likely to delay the age of"genome sequences,"or genetic profiles.By 2019 it will have become routine to map infants'genes when they are born,Dr Flatly told The Times.
This will open a new approach to medicine,by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.
A baby's genome can be discovered at birth by a blood test.By examining a person's genome,it is possible to identify raised risks of developing diseases such as cancers.Those at high risk can then he screened more regularly,or given drugs or dietary advice to lower their chances of becoming ill.
Personal genomes could also he used to ensure that patients get the medicine that is most likely to work for them and least likely to have side-effects.
The development,however,will raise legal concerns about privacy and access to individuals'genetic records.
"Bad things can be done with the genome.It could predict something about someone-and you could possibly hand the information to their employer or their insurance company."said Dr Flatley.
"People have to recognize that this horse is out of the barn,and that your genome probably can't be protected,because everywhere you go you leave your genome behind.Complete genetic privacy,however,is unlikely to be possible",he added.
As the benefits become clearer,however,he believes that most people will want their genomes read and interpreted.The risk is nothing compared with the gain.
63.In the first two paragraphs,the author mainly wants to tell us about.A
A.the significant progress in medicine
B.the promise of a leading company
C.the information of babies'genes   
D.the research of medical scientists
64.Which of the following is a problem caused by this approach?D

A.Genetic mapping technique has been widely used.
B.Genetic mapping technique is too horrible to control.
C.People are eager to improve genetic mapping technique.
D.people can't stop genetic mapping technique advancing.
66.What's Dr Flatley's attitude towards the technology?C
A.Tolerant.B.Conservative.C.Positive.D.Doubtful.

3.If  you are  interested  in  becoming  a  registered  nurse,you  are  most likely  aware that there are certain qualifications to become one.
Knowing the educational requirements to  be  a registered nurse  is the first step you   will  need  to take  in  your journey to  become  a  RN.  You will  need to  complete  a prescribed program  of study.The  education that the promising  registered  nurse  chooses  will depend on if he or she is interested in getting further education.
One of the most getting forms of education for registered nurses is an associate degree in  nursing  which takes  about two  years to  complete.  Other  RN  candidates  may  choose  a hospital diploma program where they take 30to 60hours worth of science classes and then take  many more hours of classes which are heavily focused on nursing.The diploma program usually  takes  a minimum of three years.  A diploma program meets the  basic  educational requirements to be a registered nurse.
Another choice is for the promising RN to get a Bachelor of Science degree in Nursing  from a university.Once a BSN degree is earned,it gives the person the opportunity to get  higher education opportunities in his or her field such as a Master's Degree or a PhD.
The registered nurse educational requirements can vary from state to state in America  as each state has its own laws and policies that govern the nursing profession.However,all  registered nurses must take some sort of licensing exam in order to become legally able to  practice in the registered nursing profession.
While 2to 3years of training is required,it is possible to make a good living from the salary that you can earn as a registered nurse.But be aware that the profession can be stressful.Some of the most stressful nursing positions are those in hospitals,particularly in the emergency rooms.Some less stressful jobs may include working in private practice where the hours will not be as long.

66.The main idea of this article is to talk aboutB
A.the most promising profession in the future
B.educational requirements to be a registered nurse
C.the nursing profession in different states
D.some useful information for future professions

10.The food we eat seems to have great effects on our health.Although science has made great steps in making food more fit to eat,it has,at the same time,made many foods unfit to eat.Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to diet as well.Different cultures are subject to certain illnesses because of the food that is characteristic in these cultures.That food is related to illness is not a new discovery.
In 1945,government researchers realized that nitrates(硝酸鹽) and nitrites(亞硝酸鹽),commonly used to keep color in meats,and other food additives,caused cancer.Yet,these additives remain in our food,and it becomes more difficult all the time to know which things on the packaging labels(標簽) of processed food are helpful or harmful.The additives which we eat are not all so direct.Farmers often give penicillin to cows and chick and because of this,penicillin has been found in the milk of treated cows.
Sometimes similar drugs are given to animals not for medicinal purposes,but for financial reasons.The farmers are simply trying to fatten the animals in order to get a higher price on the market.Although the FDA has tried repeatedly to control these,the practices continue.

59.How has science done a bad service to mankind?C
A.Diseases caused by food have been done away with.
B.It has caused a lack of information about the value of food.
C.Some harmful materials have been added to our food.
D.Scientists have made food more expensive to eat.
60.What are nitrates used for?B
A.They help process packaged food.
B.They keep the color in meats.
C.They cure diseases of cows and chickens.
D.They cause the animals to become fatter.
61.Which of the following statements is NOT true?A
A.You can find out harmful additives on the packaging labels of food.
B.Drugs given to animals are not all for medical reasons.
C.Researchers knew about the harm of food additives about 60years ago.
D.Food may cause forty percent of cancer in the world.
62.According to the passage,the FDA might beA.
A.a(chǎn)n organization which controls the safety of food
B.a(chǎn) producer which makes additives
C.a(chǎn) factory which processes food
D.a(chǎn) hospital which cures cancer.

20.Film cameras and digital cameras work in a similar way.
Film cameras
After all,a film camera is basically a light-proof (不透光的) box.It has a lens (鏡頭) system to focus light onto the film at the back of the camera.
Let's suppose that we are outside on a beautiful summer day trying to take a picture of the family dog.We are using a film camera.We finally get the dog to lie still.You point the camera at him.What happens?Light goes into the camera lens and hits the shutter.In other words,nothing happens yet.Now let's say that the dog looks really cute and you decide to snap a picture.What happens?When you press the button,the shutter open for a very short period of time.A small amount of light passes through and hits the film at the back of the camera.This creates an upside-down and reversed (反向的)image on the film.
    When you finish the roll of the film,you can take it to the photo shop to develop it and you will have a great picture of your dog!
    Cameras come with different lens lengths.Why does it matter?Many small cameras have shorter focal lengths,which means that there is a small distance between the lens and the place where the light focuses at the back of the camera.This gives you a large view of the area you are taking a picture of.Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger.They are often called telephoto lenses.A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them.
Digital cameras
    In digital cameras,the light falls not on film but onto a sensor (傳感器)called a CCD (Charge Coupled Device).This digitally converts(轉(zhuǎn)變) light and colour into a digital information or pixels (象素).The CCD is the heart of any digital camera and usually the most expensive part----depending on how good it is.
67.Which of the following statements is TRUE?C
A.Both digital and film cameras focus light onto the film.
B.All cameras have a sensor.
C.Digital cameras and film cameras have something in common..
D.Small cameras usually have longer focal lengths.
68.In the"Film cameras"part,you fail to take the picture of the dog becauseC.
A.light goes into the camera lens and hits the shutter
B.you haven't aimed the camera at the dog
C.the image of the dog is not created
D.the sensor fails to convert light and colour into a digital information
69.The main reason that sports photographers can get clear and big photos of players is thatD.
A.they use digital cameras                              
B.the lens of their cameras is excellent
C.their focus lenses are short                        
D.their focus lenses are long
70.Generally speaking,a digital camera's price isA.
A.closely related to the quality of the CCD
B.irrelevant to the quality of the CCD
C.closely related to the lens
D.irrelevant to the lens.

7.Quickly,the picture comes alive with hyperlinks (超鏈接),offering the names of the buildings,towers and street features that appear in the photo.The hyperlinks lead to information about the history,services and context of all the features in the photo.You have just hyperlinked your reality.
That might be a little unbelievable,but the technology exists and is no fevered imagination.This is not a cool small machine invented for the next James Bond movie; this is a working technology just developed by European researchers.It could be coming to a phone near you,and soon.
This,as the marketing types say,is a game changer.It develops a completely new interface (界面) that combines web-technology with the real world.It is big and fresh,but it goes much further and has much greater influence.
The development of the system is most outstanding because image recognition technology has long been pregnant with promise,but seemed to suffer from an unending labour.
Now MOBVIS has not only developed image recognition; it has also developed more applications for the technology; and it has adapted it to the world's most popular technology:the mobile phone.
The MOBVIS system completely rewrites the rules for exploration and interaction with your physical environment.The system begins with panoramas (一連串景象).These panoramas form the basis of a city database.It can match buildings,towers,banners and even logos that appear in the panoramas.
A user simply takes a picture of the street feature,MOBVIS compares the user's photograph to the panoramas and then identifies the buildings from the picture you take and the relevant links are returned.
Then you simply click on the links,using a touch-screen phone,and the MOBVIS system will provide information on the history,art,architecture or even the menu,if it is a restaurant,of the building in question.

67.Which is introduced in the passage?D
A.A new game software.       B.A popular mobile phone.
C.A cool small machine.      D.An image recognition system.
68.What can we learn about the new technology?C
A.It can only be put into use on mobile phones.
B.It is a little unbelievable and just a fevered imagination.
C.It has taken an unending labor to bring the technology into our lives.
D.It will encourage the users to take more pictures of the street features.
69.What is the right order of the operation of MOBVIS?B
a.A city database forms in the system.
b.MOBVIS recognizes the picture and links are returned.

4.Is a mouse that can speak acceptable?How about a dog with human hands or feet?Scientists,the people with the know-how to make such things happen,are now thinking about whether such experiments are morally right or not.
    On Nov.10,Britain's Academy of Medical Sciences launched a study on the use of animals with human materials in scientific research.The work is expected to take at least a year,but its leaders hope it will lead to guidelines for scientists in Britain and around the world on how far they can go mixing human genes into animals in search of ways to fight human diseases.
"Do these constructs (構(gòu)想) challenge our idea of what it is to be human?"asked Martin Bobrow,a professor of medical genetics at Cambridge University and chair of a 14-member group looking into the issue."It is important that we consider these questions now so that appropriate boundaries are recognized."
Using human material in animals is not new.Scientists have already created monkeys that have a human form of the Huntingdon's gene so they can study how the disease develops; and mice with livers (肝) made from human cells are being used to study the effects of new drugs.
However,scientists say the technology to put ever greater amounts of human genetic material into animals is spreading quickly around the world---raising the possibility that some scientists in some places may want to go further than is morally acceptable.
     Last year in Britain there was a lively debate over new laws allowing the creation of human-animal embryos (胚胎) for experiments.On one side of the debate were religious groups,who claimed that such science interferes with nature.Opposing them were scientists who pointed out that such experiments were vital to research cures for diseases.
The experts will publish reports after the end of the study,in which they will give definitions (定義) for animal embryos with human genes or cells,look at safety and animal welfare issues,and consider the right legal framework to work within.
72.What does the underlined word"they"in Paragraph 2 refer to?A
A.Scientists in Britain and around the world.
B.Leaders of the research.
C.Guidelines for scientists.
D.Scientific experiments.
73.Scientists do research of mixing human genes into animals in order toB
A.test new drugs on animals 
B.to find ways to fight human diseases
C.prove the research is morally acceptable
D.create monkeys and mice with livers made from human cells 
74.We can infer from the passage thatC
A.the experts will release reports after the study
B.scientists have never doubted the use of animals with human materials
C.the creation of human-animal embryos for experiments is legal in Britain
D.religious groups hold that cures for diseases have to be done through experiments
75.What would be the best title of the passage?A
A.Morally right or not?
B.A debate about new laws
C.Cures for diseases                      
D.Animal embryos with human genes.
