Every baby born a decade from now will have its genetic code (基因编码) mapped at birth, the head of the worlds’ leading genome sequencing (基因图谱) 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 be screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.
Personal genomes could also be 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.
1.In the first two paragraphs, the author mainly wants to tell us about .

It is a mystery that has puzzled doctors for decades. But experts believe they have now finally solved the tricky question of why winter is notoriously known as the flu season.
According to a new research, the influenza virus coats itself in a protective fatty shield that is tough enough to resist cold temperatures. The butter-like material only melts when it hits the respiratory tract(呼吸道), leaving the virus free to infect cells-- a process scientists say is like an M&M melting in the mouth.
However, in warmer outdoor temperatures, the protective coating melts before it reaches a person or an animal, killing the bacteria before they can infect someone. Joshua Zimmerberg, from the National Institute of Child Health and Human Development (NICHD), in the US, which led the study, said: “Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid period that the virus is able to enter a cell to infect it.”
In the past, scientists worked on theories that flu is more common in winter because people spend more time inside or the radiation from the sun in summer kills off germs. But no research successfully explained the spread of the disease.
Researchers have already claimed that the report, which is published in the journal Nature Chemical Biology, could lead to new ways to prevent and treat flu. “Now that we understand how the flu virus protects itself so that it can spread from person to person, we can work on ways to prevent it.”
Influenza and other respiratory viruses are spread in small drops broadcast by coughing, sneezing and talking and which can also settle onto surfaces, to be picked up on fingertips.

C. It is possible that flu virus will no longer threaten humans in winter.
D. People get affected by flu because they spend much more time inside in winter.
3. Where should you insert the following paragraph into the passage?
Duane Alexander, the director of NICHD, said: “The study results open new avenues of research for thwarting (使…受挫)winter flu outbreaks.”
A. Between Paragraphs 1 and 2. B. Between Paragraphs 3 and 4.
C. Between Paragraphs 4 and 5. D. Between the last two paragraphs.
4.In what process or order does flu occur?
a. The virus infects cells b. The influenza virus was born

We each have a unique genetic(基因的, 遗传的)make-up. Every cell of our body has the same set of about 100, 000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of our skin to the way our brain works. We have one of several billion combinations of DNA which come from the random mixing of our parents’ genes. Except for identical twins(同卵双胞胎), no one has the same combination as another person. We are unique! We are unique in another way, too: in the way we are raised and all the experiences we have from before birth to adult life. These experiences influence us, our behaviour and attitudes, and the choices we make.
But are genes or life experiences more important in shaping our appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births—some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.
Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit(继承). For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.
Scientists are trying to identify the different genes that influence our behavior. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.
We could ask, “Are our lives determined by our genes or our upbringing? ”Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.
1.What is the main idea of the first paragraph?
A. Both our genes and our experiences make us who we are.
B. How we turn out depends on our parents’ genes.
C. Everyone has a physical double somewhere in the world.
D. We cannot easily change our physical appearance.
2.Why are scientists studying twins?
A. To find out how many twins are born every year.
B. To discover what shapes us as individuals.
C. To compare differences between twins.
D. To study brother-and-sister relationships.
3. According to the passage, .
A. one in 70 twins are genetically identical
B. non-identical twins are usually not of the same sex
C. twins separated at birth behave exactly the same
D. identical twins are genetically the same
4.What does the underlined word “this” in Paragraph 4 refer to?
A. Our love of sports. B. Our attitude to risk-taking.
C. Our skill at bungee jumping. D. Our ability to take drugs.
