Cellphones: is there a cancer link?
Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs(电磁场) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.

The literal meaning of philosophy is “love of wisdom”.But this meaning does not tell us very much.Unlike the other disciplines(学科),philosophy cannot be defined by what you study,because it is actually unlimited.Anything can be the subject matter of philosophy: art, history, law,language,literature,mathematics,medicine,psychology,religion,science,and values.Philosophy is one of the world’s oldest subjects of study,and in fact,the other academic disciplines are directly related to philosophy.For this reason you get a Doctorate(博士学位) of Philosophy(Ph.D.) in biochemistry,or computer science,or psychology.
Two broad sub-fields of philosophy are logic and the history of philosophy.Logic is the science of argument and critical thinking.It provides sound methods for distinguishing good from bad reasoning.The history of philosophy involves the study of major philosophers and period in development of philosophy.
Of what use is philosophy?First it is useful in educational advancement.It is necessary for understanding other disciplines.Only philosophy questions the nature of the concepts used in a discipline,and its relation to other disciplines.And through the study of philosophy,one develops sound methods of research and analysis that can be applied to any field.
There are a number of general uses of philosophy.It strengthens one’s ability to solve problems,to communicate,to organize ideas and issues,to persuade,and to take what is the most important from a large quantity of data .These general uses are of great benefit in the career field,not necessarily for obtaining one’s first job after graduation,but for preparing for positions of responsibility,management and leadership later on.It is very short-sighted after all,to take a course of studies only for the purpose of getting one’s first job.The useful skills developed through the study of philosophy have significant long-term benefits in career advancement.No other discipline systematically follows the ideals of wisdom,leadership,and capacity to resolve human conflict.

Children like to imagine they are someone else in a game. As a
parent you might never guess all the way a good imagination benefits
your child. It helps a preschooler:
Develop social skills

Doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?
The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.
So while doctors may tell patients they are overweight, the conversation often ends there, said Christine C. Ferguson, director of the Stop Obesity Alliance. Without being told about options for diabetes, she said. “Doctors don’t feel they have good information to give. They felt they didn’t have adequate tools to address this problem.”
The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know at they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.
Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past — and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity-related diseases like hypertension and diabetes.
Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn., which ranks 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re going to be successful with helping your patients lose weight, you’re going to have to talk to them at virtually every visit about their progress, and find something to encourage them about, find progress in some aspect of their care and coach them,” he said.
He acknowledged that many doctors tend to be optimistic.
“Part of this is that there’s this common belief, and doctors are burdened by it, too, that heavy people are weak-willed and just don’t have any willpower and are self-indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”
61.What is most probably the Stop Obesity Alliance, as in Paragraph 3?
A.An organization of doctors specializing in obesity.
B.An organization of patients suffering from obesity.
C.A research group that conducts special surveys about overweight people.
D.A research group dealing with doctor – patient relationship.
62.How many of the patients surveyed have been advised by their doctors to lose weight?

A.They are not as hopeless as doctors think they are.
B.Most of them have tried hard to lose weight, but in vain.
C.Without their doctors’ constant coaching, there is little chance of their succeeding in losing weight.
D.Most of them have just given up their hope of becoming less heavy.
64.According to the passage, which factor contributes to the lack of dialogue between doctors and patients?
A.Most doctors just never think of warning their patients about their weight problem.
B.Many doctors find it difficult to persuade overweight people to lose weight.
C.Most patients are too weak – willed to do anything about their weight.
