Many women who battle breast cancer will tell you it's a life-changing experience. However, a new study shows that for many (51) , the changes aren't always positive or permanent.
Beth Snoke has watched her mother and both grandmothers battle and survive breast (52) So when she was diagnosed, there was no doubt in her mind (53) she had to do.
"I do exactly what the doctors say as far as the medicine that I'm on, as (54) as the vitamins, the diet, and the fitness. And I can't stress enough (55) important that is," says Beth Snoke. But a surprising new study shows that (56) every woman who beats breast cancer is getting that message. In fact, nearly 40% of them say even (57) surviving breast cancer, they haven't made significant changes in the (58) they eat or how much they exercise.
"Not all survivors are taking advantage of this teachable moment and making positive health changes in (59) life," says Electra Paskett, PhD, at Ohio State University's Comprehensive Cancer Center. Paskett says diet and exercise have been proven to not only help women feel better during and after treatment, they may (60) play a role in preventing some cancers from coming back (61) growing evidence, some women just aren't listening.
"Colon cancer survivors (62) exercise have actually been shown to have improved survival rates. So, yes, it is true that perhaps by making some of these healthy choices we can actually increase their health," says Paskett.
As a breast cancer survivor (63) , Paskett knows first hand how much difference diet and exercise can (64) The challenge, she says, is to get more survivors to be more like Beth, during and after treatment.
Experts say exercising more and eating a healthier diet can also cut (65) on stress and help women overcome depression. There are more than 2 million breast cancer survivors living in the U.S. Of those, nearly a million have yet to change their diet or exercise routines.

Most people have experienced the feeling, after a taxing mental work-out, that they cannot be bothered to make any more decisions. If they are forced to, they may do so intuitively, rather than by reasoning. Such apathy is of ten put down to tiredness; but a study published recently in Psychological Science suggests there may be more to it than that. Whether reason or intuition is used may depend simply on the decision-maker's blood-sugar level—which is, itself, affected by the process of reasoning.
E.J. Masicampo and Roy Baumeister of Florida State University discovered this by doing some experiments on that most popular of laboratory animals, the impoverished undergraduate. They asked 121 psychology students who had volunteered for the experiment to watch a silent video of a woman being interviewed that had random words appearing in bold black letters every ten seconds along the perimeter of the video. This was the part of the experiment intended to be mentally taxing. Half of the students were told to focus on the woman, to try to understand what she was saying, and to ignore the words along the perimeter. The other half were given no instructions. Those that had to focus were exerting considerable serf-control not to look at the random words.
When the video was over, haft of each group was given a glass of lemonade with sugar in it and half was given a glass of lemonade with sugar substitute. Twelve minutes later, when the glucose from the lemonade with sugar in it had had time to enter the students' blood, the researchers administered a decision-making task that was designed to determine if the participant was using intuition or reason to make up his mind.
The students were asked to think about where they wanted to live in the coming year and given three accommodation options that varied both in size and distance from the university campus. Two of the options were good, but in different ways: one was far from the campus, but very large; the other was close to campus, but smaller. The third option was a decoy, similar to ope of the good options, but obviously not quite as good. ff it was close to campus and small, it was not quite as close as the good close option and slightly smaller, if it was far from campus and large, it was slightly smaller than the good large option and slightly farther away.
Psychologists have known for a long time that having a decoy option in a decision-making task draws people to choose a reasonable option that is similar to the decoy. Dr. Masicampo and Dr. Baumeister suspected that students who had been asked to work hard during the video and then been given a drink without any sugar in it would be more likely to rely on intuition when making this decision than those from the other three groups. And that is what happened; 64% of them were swayed by the decoy. Those who had either not had to exert mental energy during the showing of the video or had been given glucose in their lemonade, used mason in their decision-making task and were less likely to be swayed by the decoy.
It is not clear why intuition is independent of glucose. It could be that humans inherited a default nervous system from other mammals that was similar to intuition, and that could make snap decisions about whether to fight or flee regardless of how much glucose was in the body.
Whatever the reason, the upshot seems to be that thinking is, indeed, hard work. And important decisions should not be made on an empty stomach.
The word "taxing" in the fast paragraph means
A．tiring.
B．imposing taxation.
C．paying taxation.

Aspirin may be the most familiar drug in the world — but its power to heal goes far beyond the usual aches and pains. Exciting new studies suggest that aspirin can help fight a wide range of serious illnesses. "It now seems to be a benefit in so many areas of health," says Dr Debra Judelson, medical director of the Women's Heart Institute in Beverly Hills, California. "I advise most of my patients, as long as they aren't allergic to aspirin and don't have bleeding problems, to take low-dose aspirin."
Some of the major illnesses and conditions that aspirin or aspirin-like drugs might help prevent are. Alzheimer's disease, diabetes-related heart disease, heart attack, cancer and antibiotic-induced hearing loss.
The passage mainly discusses the effects of
A．health.
B．aspirin.
C．hearing loss.
D．heart attack.

Researchers who picked up and analyzed wild chimp droppings said on Thursday they had shown how the AIDS virus originated in wild apes in Cameroon and then spread in humans across Africa and eventually the world. Their study, published in the journal Science, supports other studies that suggest people somehow caught the deadly human immunodeficiency ,virus (HIV) from chimpanzees, perhaps by killing and eating them.
"It says that the chimpanzee group that gave rise to HIV… this chimp community resides in Cameroon," said Beatrice Hahn of the University of Alabama, who led the study. "But that doesn’t mean the epidemic originated there because it didn’t," Hahn, who has been studying the genetic origin of HIV for years, said in a telephone interview.
"We actually know where the epidemic took off. The epidemic took off in Kinshasa, in Brazzaville." Kinshasa is in the Democratic Republic Congo, formerly Zaire, and faces Brazzaville, in Congo, across the Congo River. Studies have traced HIV to a man who gave a blood sample in 1959 in Kinshasa, then called Leopoldville. Later analysis found the AIDS viros.
In people, HIV leads to AIDS but chimps have a version called simian immune deficiency virus (SIV) that causes them no harm. Humans are the only animals naturally susceptible to HIV. AIDS was only identified 25 years ago. The virus now infects 40 million people around the world and has killed 25 million. Spread in blood, sexual contact and from mother to child during birth or breastfeeding, HIV has no cure and there is no vaccine, although drug cocktails can control it.
And like so many new infections, AIDS appears to have been passed to humans from animals they slaughtered. SIV has been found in captive chimps but Hahn wanted to show it could be found in the wild too. Her international team got the cooperation of the government in Cameroon and they hired skilled trackers.
"The chimps in that area are hunted. It’s certainly impossible to see them. It is hard to track them and find these materials," she said. But the trackers managed to collect 599 samples of droppings. Hahn’s lab found DNA, identified each individual chimp and then found evidence of the virus.
"We went to 10 field sites and we found evidence of infection in five. We were able to identify a total of 16 infected chimps and, we were able to get viral sequences from all of them," Hahn said. Up to 35 percent of the apes in some communities were infected. Not only that, they could find different varieties, called clades, of the virus.
"We found some of the clades were really, really very closely related to the human virus and others were not," she said. Chimps separated by a fiver were infected with different clades, Hahn said. And a river may have carded the virus into the human population. "So how do you get from southern Cameroon to the Democratic Republic of Congo？" Hahn asked. "Some human must have done so. There is a river that goes from that southeastern comer of Cameroon down to the Congo River."
Ivory and hardwood traders used the Sangha River in the 1930s, when the original to-human transmission is believed to have happened. Haha’s study suggests the virus passed from chimpanzees to people more than once. "We don’t really know how these transmissions occurred," Hahn said.
"We know that you don’t get it potting a chimp, or from a toilet seat, just like you can’t get HIV from a toilet seat. It requires exposure to infected blood and infected body fluids. So if you get bitten by an angry chimp while you are hunting it, which could do it."
Hahn’s study only applies the H1V group M, which is the main strain of the virus responsible for the AIDS pandemic. "It’s quite possible that still other (chimpanzee SIV) lineages exist that could pose risks for human infection and prove problematic for HIV diagnostic and vaccines," her team wrote.

B．Kinshasa and Brazzaville.
C．Congo River.
D．Nile River.
