2010年北京东城区高三二模英语试题及答案(5)

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.

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
