What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology. With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cell, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometimes between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs (The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones).
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

Young sunflowers turn and swing every day. New findings add to evidence that the plants are animal-like.
Harmer, a professor in the University of California at Davis’ Department of Plant Biology, carried out a series of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.
By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.
The indoor plants did start tracking the “sun” again when the apparent source of lighting was moved across the room. The plants could reliably track the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.
When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day, or on the other side at night. A plant growth-regulating hormone, called auxin, appears to be a key driver.
The “dance” to the sun cycle obviously slows when the sunflower matures and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.
“Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.
“The morning warmth changes the flowers in a way to make them more appealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said. “We’re currently testing this idea.”

The chicken-loving dog spent last month guarding the island’s penguin colony, with great success.
A SOUTH-WEST Victorian chicken farmer known as Swampy and his dog Oddball may have found a way to save some of Australia’s endangered wildlife from enemies. After Warrnambool’s once flourishing penguin population was killed in large numbers by foxes and dogs until only 27 remained, Allan Swampy Marsh hatched an effective plan to save the birds. His four sheepdogs had been protecting his chickens against enemies for a decade. He figured they could do the same for the penguins. “The difficulty was trying to convince all the wildlife wallies to think outside the square,” Mr Marsh said. “It’s not an unselfish view of penguins or chicks but the sense of territory (领地) that makes the dogs work, and it is far stronger in these dogs than any other trained breed.”
Oddball’s work as guardian of Middle Island’s colony last month was a success. At the end of the month, 70 pairs of happy feet were counted returning to the island. About 2,000 penguins occupied the island in the 1990s. “Oddy is really protective of the chicks, so to her the penguins were only chicks in dinner suits,” Mr Marsh said. Highly territorial dogs have been bred in Italy to guard livestock for 2,000 years. They manage to keep off trouble makers such as foxes and dogs. The trial’s success has generated interest from overseas. The use of guard animals such as dogs — and even alpacas, which also stop foxes — is now being considered to save other endangered species such as the eastern barred bandicoot.

A.They had been killed by other animals.
B.They had been scared away by people.

D.They had been taken to another island for protection.
2.About how many penguins were on the island when it had the largest number?
A.27. B.70.
C.1990. D.2000.

5.The purpose of the last paragraph is to suggest that________.
