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.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.
65.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.
66.What’s Dr Flatley’s attitude towards the technology?
A.Tolerant. B.Conservative. C.Positive. D.Doubtful.

The Touchstone
When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and so a poor man, who could read little, bought it for very little money.
The book wasn't very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the "Touchstone"! The touchstone was a small pebble that could turn any common metal into pure gold.
The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.
So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold - throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea. The days continued over a long period if time.
One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
So it is with opportunity. Unless we are cautious, it’s easy to fail to recognize an opportunity when it is in hand and it’s just as easy to throw it away.
59.The man bought the book because .
A.he wanted to read it B.it was very interesting
C.there was a secret in the book D.he wanted to find the touchstone
60.We can learn from the passage that the touchstone is .
A.pure B.cold C.magic D.big
61.Why did the man throw the pebbles into the sea?
A.Because he didn’t want to get the same pebbles.
B.Because he didn’t want others to pick them up.
C.Because he didn’t like their ordinary looks.
D.Because he didn’t like the cold feelings.
62.What does the author want to tell us in the passage?
A.We about orate opportunities in our life.
B.We should seek for opportunities in the world.
C.We may seize opportunities when we are watchful
D.We may discover opportunities when forming habits.

Eight – year – old Jesse Abrogate was playing in the sea late one evening in July 2001 when a 7 – foot bull shark attacked him and tore off his arm. Jesse’s uncle jumped into the sea and dragged the boy to shore. The boy was not breathing. His aunt gave him mouth – to – mouth resuscitation (人工呼吸) while his uncle rang the emergency services. Pretty soon, a helicopter arrived and flew the boy to hospital. It was a much quicker journey than the journey by road.
Jesse’s uncle, Vance Folsenzier, ran back into to the sea and found the shark that had attacked his nephew. He picked the shark up and threw it onto the beach. A coastguard shot the fish four times and although this did not kill it, the shark’s jaws relaxed so that they could open them, and reach down into its stomach, and pull out the boy’s arm.
At the Baptist Hospital in Pensacola, Dr Ian Rogers spent eleven hours reattaching Jesse’s arm. “It was a complicated operation,” he said, “but we were lucky. If the arm hadn’t been recovered in time, we wouldn’t have been able to do the operation at all. What I mean is that if they hadn’t found the shark, well then we wouldn’t have had a chance.”
According to local park ranger Jack Tomosvic, shark attacks are not that common. “Jesse was just unlucky,” he says, “evening is the shark’s feeding time. And Jesse was in area without lifeguards. This would never have happened if he had been in area where swimming is allowed.”
When reporters asked Jesse’s uncle how he had had the courage to fight a shark, he replied, “I was mad and you do some strange things when you’re mad.”
56.What was the boy doing when the accident happened?
A.Feeding a hungry shark. B.Jumping into the rough sea.
C.Dragging a boy to the shore. D.Swimming in a dangerous area.
57.In which way did the boy’s uncle help with the operation?
A.By finding his lost arm. B.By shooting the fish.
C.By flying him to hospital. D.By blowing into his mouth.
58.How was his uncle in time of danger?
A.Careful. B.Brave. C.Optimistic. D.Patient.
