Every day born a decade from now will have its genetic code(基因编码)mapped at birth, the head of the world’s 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__________.
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?

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. people can’t stop genetic mapping technique advancing.
C. People are eager to improve genetic mapping technique.
D. Genetic mapping technique is too horrible to control.
4.What’s Dr Flatley’s attitude towards the technology?

Like every dog, every disease now seems to have its day. World Tuberculosis (infections disease in which growths appear on the lungs) Day is on Saturday March 24th.
Tuberculosis was once terribly fashionable. Dying of “consumption” seems to have been a favorite activity of garret-dwelling 19th-century artists, has, however, been neglected of late. Researchers in the field never tire of pointing out that TB kills a lot of people. According to figures released earlier this week by the World Health Organization, 1.6 million people died of the disease in 2005, compared with about 3m for AIDS and 1m for malaria. But it receives only a fraction of the research budget devoted to AIDS. America’s National Institutes of Health, for example, spends 20 times as much on AIDS as on TB. Nevertheless, everyone seems to getting in on the TB-day act this year.
The Global Fund an international organization responsible fur fighting all three diseases but best known for its work on AIDS, has used the occasion to trumpet its tuberculosis projects. The fund claims that its anti-TB activities since it opened for business in 2002 have saved the lives of over 1m people. The World Health Organization has issued a report that contains some good news. Although the number of TB cases is still rising, the rate of illness seems to have stabilized; the caseload, in other words, is growing only because the population itself is going up.
Even drug companies are involved. In the run-up to the day itself, Eli Lilly announced a $ 50m boost to its MDRTB Global Partnership. MDR stands for multi-drug resistance, and it is one of the reasons why TB is back in the limelight. Careless treatment has caused drug-resistant strains to evolve all over the world. The course of drugs needed to clear the disease completely takes six mouths, anti persuading people to stay that course once their symptoms have gone is hard. Unfortunately, those infected with MDR have to be treated with less effective, more poisonous and more costly drugs. Naturally, these provoke still more. non-compliance and thus still more evolution.
The other reason TB is back is its relationship to AIDS. The (global Fund’s joint responsibility for the diseases is no coincidence. AIDS does not kill directly. Rather, HIV, the virus that causes it, weakens the body’s immune system and exposes the sufferer to secondary infections. Of these, TB is one of the most serious. It kills 200 000 AIDS patients a year. However, some anti-TB drugs interfere with the effect of some anti-HIV drugs. Conversely, in about 20% of cases where a patient has both diseases, anti-HIV drugs make the tuberculosis worse. The upshot is that 125 years after human beings worked out what caused TB, it is still a serious threat.

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.
1. What can be the best title of the passage?
A. The mystery that has puzzled doctors for decades. B. New ways to prevent and treat flu.
C. A discovery of how flu strikes in Winter. D. Ways found to prevent flu.
2. Which of the following statements is NOT true?
A. Doctors have been trying hard to discover why flu strikes in winter.
B. In the past, scientists didn’t know how flu spreads.
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
c. The butter-like material melts d. The virus hits respiratory tract
e. The virus coats itself in butter-like shield f. The virus is free
A. a, c, d, e, b, f . B. c, f, d, b, e, a. C. b, e, d, c, f, a. D. d, b, e, c, f, a.
