1、US Signs Global Tobacco Treaty1     The United States has taken the first step toward approving a global tobacco treaty that promises to help control the deadly effects of tobacco use throughout the world. Health and Human Services Secretary Tommy Thompson signed the Framework Co

2、nvention on Tobacco Control (FCTC) this week at the United Nations. The Senate must still approve the treaty before the US can implement its provisions.2     The FCTC was developed by the World Health Organization and approved by members of the World Health Assembly，including the

3、 United States，last year. Countries that ratify it would be required to enact strict tobacco control policies.3     For instance, cigarettes sold in those countries would have to have health warnings on at least 30% of the front and back of every pack. The treaty calls for higher

4、 tobacco taxes, restrictions on smoking in public places, and more promotion of tobacco prevention and cessation programs. It also requires bans on tobacco advertising, though there are some exceptions for countries like the United States, where the Constitution prohibits such an outright ban.4 

5、;    The impact of the treaty could be huge. The World Health Organization estimates that tobacco use kills nearly 5 million people worldwide every year. In the US alone, about 440,000 people die each year from tobacco-related illnesses; about one-third of all cancers in the US are ca

6、used by tobacco use. If current trends continue, WHO estimates, by 2025 tobacco will kill 10 million people each year.5     The treaty must be ratified by at least 40 countries before it can take effect. So far，109 countries have signed it, and 12 have ratified it.A  &#

12、 and feeling refreshed after a nights sleep than 8-hour sleepers.23These findings, which DrDaniel Kripke reported in the journal Psychosomatic Medicine3, demonstrate that people who want to get a good nights rest may not need to set aside4 more than 8 hours a nightHe added that “it might be a g

20、#160;  An animal that influenced scientific thought has died. A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the American state of Washington. Washoe had become known in the scientific community1 and around the w

21、orld for her ability to use American Sign Language2. She was said to be the first non-human to learn a human language. Her skills also led to debate3 about primates and their ability to understand language.2.     Research scientists Allen and Beatrix Gardner began teaching W

22、ashoe sign language in 1966. In 1969, the Gardeners described Washoe's progress in a scientific report. The people who experimented with Washoe said she grew to understand4 about 250 words. For example, Washoe made signs to communicate when it was time to eat. She could request foods like a

23、pples and bananas. She also asked questions like, "Who is coming to play?" Once5 the news about Washoe spread, many language scientists began studies of their own6 into this new and exciting area of research. The whole direction of primate research changed.3.   

24、60; However, critics argued Washoe only learned to repeat sign language movements from watching her teachers. They said she had never developed true language skills. Even now, there are some researchers who suggest that primates learn sign language only by memory, and perform the signs only for priz

25、es. Yet Washoe's keepers disagree. Roger Fouts is a former student of the Gardeners7. He took Washoe to a research center in Ellensburg, Washington. There, Washoe taught sign language to three younger chimpanzees, which are still alive.4.     Scientists like private researche

26、r Jane Goodall believe8 Washoe provided new information about the mental workings of chimpanzees. Today, there are not as many scientists studying language skills with chimps. Part of the reason is that this kind of research takes a very long time.5.     Debate continues abo

32、d Frend simply declared it to be neurotic.2. Experience shows that looking on the bright side of life does have advantages and recent scientific evidence points to the positive mindset as being beneficial to health. In other words optimists live longer.3. That was the conclusion reached by experts a

33、t the Mayo Clinic in the U. S. State of Minnesota who evaluated answers given by people to a set of questions in the 1960s. Of the 729 candidates, 200 had died and according to scientists, there were a disproportionate number of pessimists among them.4. Ten points more on the pessimism scalethat was

34、 the difference between “slightly pessimistic” and “averagely pessimistic” were enough to boost a persons chances of dying by 19 percent, according to the study by prominent psychologist Martin Seligman of the University of Pennsylvania.5. The study does not say why pessimists die but an older surve

35、y taken among children in San Francisco and Los Angeles makes it clear that personal attitude towards the world is a key factor in the longevity equation.6. The latest evidence to support the theory that optimists tend to cope better with illness of all kinds has been provided by Professor Ralf Schw

36、arzer of Berlin's Free University who questioned 600 heart and lung patients. His conclusion: Optimists recover more swiftly from operations than their pessimistic counterparts; tend to be happier after treatment and return to work more swiftly.7. There have been suggestions that optimists do no

37、t stay healthier but rather turn into optimists later because they enjoy good health. Numerous surveys have taken into account a person's state of health at the outset and the effect remains the same.8. Studies have shown that optimists do not blind themselves to reality either. They thus interp

38、ret it in a positive way. “Sublimating and denying things tend to alter reality but illusions are a way of seeing reality in the best light.” said Californian psychology professor Shelley Taylor.9. German science journal “Bildder Wissenschaft”, which carries a major article on the topic in its curre

It seems psychotherapy can go some way towards extending the life span and life quality of a sick person although a complete recovery using psychological technique alone is unlikely.11.

The magazine also quoted a study by Sheldon Cohens of the Carnegie-Mellon-University in Pittsburgh:

41、 420 volunteers were deliberately infected with strains of various common cold viruses. A day later checks were carried out to see who had caught a cold.13. The results showed that in the case of people who had satisfactory, long-term relations with friends neighbors or colleagues, the virus was les

Whether widespre

45、ad use of masks will help, or harm, during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them in certain situations anyway, just in case1.2But it

46、9;s a question the public keeps asking while the government are making preparations for the next flu pandemic. So the Centers for Disease Control and Prevention (CDC) came up with2preliminary guidelines. "We don't want people wearing them everywhere," said the CDC. "The overall re

47、commendation really is to avoid exposure."3When that's not possible3, the guidelines say to consider wearing a simple surgical mask if you are in one of the three following situations. First, you're healthy and can't avoid going to a crowded place. Second, you're sick and think

48、you may have close contact with the healthy, such as a family member checking on you4. Third, you live with someone who's sick and thus might be in the early stages of infection, but still need to go out.4Influenza pandemics can strike when the easy-to-mutate flu virus shifts to a strain that pe

49、ople never have experienced. Scientists cannot predict when the next pandemic will arrive, although concern is rising that the Asian bird flu might trigger one if it starts spreading easily from person to person.5During the flu pandemic, you should protect yourself. Avoid crowds, and avoid close con

50、tact with the sick unless you must care for someone. Why aren't masks added to this self-protection list? Because they can help trap virus-laden droplets flying through the air with a cough or sneeze. Simple surgical masks only filter the larger droplets. Besides, the CDC is afraid masks may cre

51、ate a false sense of security. Perhaps someone who should have stayed home would don an ill-fitting mask and hop on the subway5 instead.6Nor does flu only spread through the air6. Say7 someone covers a sneeze with his or her hand, then touches a doorknob or subway pole8. If you touch that

52、spot next and then put germy hands on your nose or mouth, you've been exposed. It's harder to rub your nose while wearing a mask and so your face may get pretty sweaty under masks. You reach under to wipe that sweat, and may transfer germs caught on the outside of the mask straight to the no

53、se. These are the problems face masks may create for their users.7Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing. AReasons for Excluding Masks from the Self-pro
