　　As people continue to grow and age, our body systems(系统)continue to change．At a certain point in your life your body system will begin to weaken．Your strength may become weaker．It may become more difficult for you to see and hear．The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury．In order to live longer, we have always tried to slow or stop this change that leads us toward the end of our lives．

　　Many factors(因素)decide your health．A good diet plays an important role．The amount and type of exercise you get is another factor．Your living condition is yet another．But scientists studying aging problem want to know：Why do people grow old?They hope that by studying the aging medical science they may be able to make the length of life longer．

　　There is nothing to be afraid of as old age comes．Many consider the later part of life to be the best time for living．Physical activity may become less, but often you get better understanding of yourself and the world．

　　What we consider old age now may only be middle-aged some day soon．Who knows, with so many advances in medical science happening so quickly, life length may one day be measured in centuries, rather than in years!

Is a recently discovered hormone the reason why folks who lose weight can’t keep it off?
Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just fat. After trying all sort of diets that didn’t work, she has to go to the stomach – bypass surgery (胃部迂回手术), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most. Result: she simply couldn’t eat the way she used to. In three years, Wilson is one third of her former weight.
Wilson’s experience is not all that unusual, and while doctors still aren’t exactly sure what is going on, a report in last week’s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason we feel hungry and it’s hare for didters to keep weight off.
Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the leading Dr. David of the University of Washington says, “I feel very solid about two of them.” The first is that ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is that ghrelin levels are higher on average in people who have lost weight from dieting.
Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as most people of normal weight. After all, ghrelin is produced by cells in the stomach. Years ago, leptin, a hormone was found as an appetite suppressant (食物抑制剂). But after years of trying, it had to be given up.
What doctors suspect is that both leptin and ghrelin are part of a complex system of brain and body chemicals that govern weight and appetite. That does not mena pharmaceutical (药物的) weight control is forever out of the question. “In the next ten years, we will be able to develop new drugs to help people lose weight healthily and effectively.”
47．What can we learn about ghrelin according to the passage?
A．After meals ghrelin levels are higher in the bloodstream.
B．People who have lost weight have less ghreilin in their body.
C．Without ghrelin, people are really difficult to lose weight.
D．Ghrelin is something produced by cells in the stomach.
48．What is Dr. David not sure?
A．pharmaceutical weight control is impossible.
       B．There is less ghrelin in the bypass patients.
C．new drugs will be developed in 10 years.
D．ghrelin levels are higher in people on diet.
49．In fact, people’s weight and appetite are controlled by
A．ghrelin and leptin                      B．hormone and medicine
C．brain and body chemicals                  D．stomach and food
50．What can we infer from the passage?
A．People with a lower ghrelin level go hungry easily.
B．Doctors managed to use leption to control the appetite.
C．Doctors are optimistic about how to lose weight healthily.
D．The loss of appetite in bypass aptient is linked to leptin

LONDON (Reuters) Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers.

Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.

"Evidence is growing that many animals do not react well to tourists in their backyard，” New Scientist magazine said.

The immediate effects "researchers have noticed are changes in behavior, heart rates. or stress hormone levels but they fear it could get much worse and over the long term “ could endanger the survival of the very wildlife they want to see. ”

Although money produced through ecotourism, which has been growing at about 10-30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited（审计） and based on environmentally friendly policies，according to the magazine.

Transmission of disease to wildlife，or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding，” said Philip Seddon , of the University of Otago in Dunedin, New Zealand.

Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by colorists are producing smaller babies.

Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started.

“The animals’ welfare should be very important because without them there will be no ecotourism，” said Rochelle Constantine of the University of Auckland in New Zealand
