Alaskan black bears hibernate for up to ...

Alaskan black bears hibernate for up to seven months a year, during which time they do not eat or drink, before waking up in virtually the same physical state they fell asleep in.

    Now experts hope to develop methods of putting humans into a similar state which could help astronauts survive long missions and lead to new ways of treating severely ill patients.

    While many studies have examined hibernation in mice and hedgehogs, little research has been done into the same condition in larger mammals such as bears.

    But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the animals' body temperature, heart rate and muscle movements while they slept.

    The research results showed that during a five-month hibernation the bears’ body temeratures varied between 30℃ and 36℃ in cycles that lasted between two and seven days—a pattern that was previously unknown in hibernating animals.

    The research project leader said, "If our research could help by showing how to reduce metabolic(新陈代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply need to know how to turn things on and off to take advantage of the different levels of hibernation."

    Craig Heller, of Stanford University, who contributed to the study, added: "There has always been a thought that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower metabolism or a state of hibernation. That's almost science fiction but you can see the logical basis."

    Four common bad habits combined—smoking, drinking too much, inactivity and poor diet—can age you by 12 years, sobering new research suggests.

The findings are from a study that tracked nearly 5,000 British adults for 20 years, and they highlight yet another reason to adopt a healthier lifestyle.

Overall, 300 people studied had all four unhealthy behaviors. Among them, 90 died during the study, or 30 percent. Among the 400 healthiest people with none of the four habits, 8 percent of them died.

The risky behaviors were: smoking tobacco; downing more than three alcoholic drinks per day for men and more than two daily for women; getting less than two hours of physical activity per week; and eating fruits and vegetables fewer than three times daily.

These habits combined substantially increased the risk of death and made people who engaged in them seem 12 years older than people in the healthiest group, said lead researcher Elisabeth Kvaavik of the University of Oslo.

The healthiest group included never-smokers and those who had quit; teetotalers, women who had fewer than two drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly; and those who ate fruits and vegetables at least three times daily.

"You don't need to be extreme" to be in the healthy category, Kvaavik said. "These behaviors add up, so together it's quite good. It should be possible for most people to manage to do it."

    The US government generally recommends at least 4 cups of fruits or vegetables daily for adults, depending on age and activity level, and about 2 hours of exercise weekly.

1.What problem may you have, if you smoke often and eat few fruits and vegetables?

    A.You would have difficulty in walking.                   B.You would feel tired, lack of energy.

    C.You may look older than you really are.                 D.You may face the risk of death of cancer.

 

2.How many of the 400 healthiest people with none of the four habits died?

    A.32.             B.24.            C.56.            D.120.

3.What does this text mainly talk about?

    A.Suggestions to smokers.             B.The results of four bad life habits.

    C.The findings of a new research.                         D.The recommends from the US government.

    A middle-aged stranger visited us late on a dark rainy night when my father was working the night shift (a job for a period during the night). The stranger asked if he could wait under the eaves of our roof for the rain to stop. Then he disappeared, and we started hearing footsteps and creaking boards in the attic(the space or room at the top of a building, under the roof, often used for storing things). Was the stranger inside our house? My whole body couldn’t help but stiffen. In my mind’s eye, I could imagine the stranger pushing through the attic door and approaching us.

    We immediately called Jerry, our neighbor, for help. He searched everywhere, but the visitor was nowhere to be found. As Jerry looked in the garage, he found the stranger lying underneath the car. Jerry exclaimed with fright, “You are not allowed to enter the house. Get off the property right now.”
