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 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.

1.In the first two paragraphs, the author mainly wants to tell us about______.

      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

2.Which of the following is a problem caused by this approach?

       A.The delaying in discovering DNA.

       B.The risk of developing diseases at birth.

       C.The side – effects of medicine on patients.

       D.The letting out of personal genetic information.

3.What does the underlined sentence “… this horse is out of the barn” mean?

       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.

4.What’s Dr Flatley’s attitude towards the technology?

       A.Tolerant.     B.Conservative.         C.Positive.      D.Doubtful.

The fighting against youth smoking since I took office I’ve done everything in my power to protect our children from harm. We’ve worked to make their streets and their schools safer, and to give them something positive to do after school before their parents get home. We’ve worked to teach our children that drugs are dangerous, illegal and wrong.

Today, I want to talk to you about the historic opportunity we now have to protect our nation’s children form an even more deadly threat: smoking. Smoking kills more people every day than AIDS, alcohol, car accidents, murders, suicides, drugs and fires combined. Nearly 90 percent of those smokers lit their first cigarette before they turned 18. Consider this: 3,000 children start to smoke every day illegally, and 1,000 of them will die sooner because of it. This is a national tragedy(悲剧)that every American should be honor-bound to help prevent. For more than five years we’ve worked to stop our children from smoking before they start, launching(发动)a nationwide campaign(运动)to educate them about the dangers of smoking, to reduce their access to tobacco products, and to severely restrict(限制)tobacco companies from advertising to young people. If we do these, we’ll cut teen smoking by almost half over the next five years. That means if we act now, we have it in our power to stop 3 million children from smoking and to save a million lives as a result.
