Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said: "In the UK 61.4 per cent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started."
The "Food: Body: Mind" report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they are currently on a diet and one in five women said they are on a "continuous diet".
It found the most common triggers to start dieting was seeing their "reflection in the mirror", preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half.
However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers who polish off their children"s leftovers was another common cause of weight gain.

Researchers from the University of Chicago asked volunteers to remember simple words．Many found their memories letting them down towards the end of the day, but the following morning, those who had slept well could recall much more.
Researchers, writing in the journal Nature, said the brain could “rescue” lost memories during the night.
When the brain is first asked to remember something that memory is laid down in an “unstable” state, meaning that it is possible that it could be lost．At some point, the brain consolidates those it deems important into a “stable”, more permanent state．However, the Chicago researchers suggested that it was possible for a “stable” memory to be made “unstable” again．This would mean that memories could be modified then filed away again in the face of new experiences.
The 12 volunteers tested in the experiment were played words created through a speech synthesizer which were purposely difficult to understand．Initially, the written version of the word from the audio version only．Tests revealed that the ability to recall the right word tended to tail off as the day ended.
However, when the volunteers were retested after a good night’s sleep, they were able to recall some words that they had “ forgotten” the previous evening.
Dr Daniel, one of the study authors, said: “Sleep consolidates memories, protecting them against subsequent interference or decay．Sleep also appears to “recover” or restore memories.” He said: “If performance is reduced by decay, sleep might actively recover what has been lost.”
Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: “Memory research is undergoing a transformation---no longer is memory thought to be a hard-writing of the brain, instead it seems to be a process of storage and restorage.”
Sleep helps some memories “mature” and also prunes out unimportant memories.
小题1:What does the first paragraph implies?
| A．A busy day makes people forget things easily. |
| B．People need a good night’s sleep after a busy day. |
| C．A good night’s sleep helps memories. |
| D．A good night’s sleep helps people forget a busy day. |
| A．created through a speech synthesizer |
| B．hard to understand |
| C．available at the beginning |
| D．designed to test people’s ability of understanding |
| A．is a hard-writing of the brain |
| B．is not a process of storage |
| C．is not a process of restorage |
| D．will be mature with the help of sleep |
| A．When people first remember something, the memory is in an “unstable state”. |
| B．The brain will change those important unstable memories into stable. |
| C．Once the memory become stable, it will never become unstable again. |
| D．Sleep can protect memories from being harmed. |
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu(流感), and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome(综合症) ，a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
小题1: According to the author, knowing the cause of the misery will help ________.
| A．shorten the duration of the illness |
| B．the patient buy medicine over the counter |
| C．the patient obtain cheaper prescription drugs |
| D．prevent people from catching colds and the flu |
| A．one doesn’t need to take any medicine if he has a cold or the flu |
| B．aspirin should not be included in over-the-counter medicines for the flu |
| C．delayed treatment of the flu will harm the liver and central nervous system |
| D．over-the-counter drugs can be taken to ease the misery caused by a cold or the flu |
| A．one should identify the virus which causes it |
| B．one should consult a doctor as soon as possible |
| C．one should take medicine upon catching the disease |
| D．one should remain alert when the disease is spreading |
| A．A stuffy nose. | B．A high temperature. |
| C．A sore throat. | D．A dry cough. |
| A．are advised not to give them aspirin |
| B．should watch out for signs of Reye syndrome |
| C．are encouraged to take them to hospital for vaccination |
| D．should prevent them from mixing with people running a fever |
A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.Researchers from the University of Yale based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanomas (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles (雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.小题1:The underlined word “flaws” in the 2nd paragraph most probably means .
| A．evidences | B．facts | C．faults | D．failures |
| A．seldom use sunscreen | B．are more in danger of skin cancer | C．can be free from the harm of the sun | D．often expose themselves to the sun |
| A．sunscreen users get skin cancer more often | B．the volunteers have prov ed the effect of sunscreen | C．the new study was based on the experiences of volunteers | D．the number of skin cancer patients is increasing in America |
| A．Sunscreen to Prevent Skin Cancer | ||
| B．Sunscreen to Increase Skin Cancer | C．Skin Cancer Caused by Sunscreen | D．Skin Cancer Caused by Freckles |
Liu and coach Sun Haiping were followed away by officials after arriving at Shanghai Pudong airport at around 6 : 30 p. m. , and said nothing to the waiting media.
Liu went straight to the Xinzhuang training base in Shanghai, where he will start on the comeback (恢复) through rehabilitation (复职) and training.
Feng Shuyong, vice-director of China"s Athletics Administrative Center, said a group of experts is on standby at the training base to help with Liu"s recovery.
"The experts will give Liu a full check-up tomorrow or the day after and advise regularly on rehabilitation in the coming months," Feng was quoted by qq. com as saying.
The foot injury forced defending champion Liu to quit from the 2008 Beijing Olympics last August after "he limped out of the Bird"s Nest in the first round of the men"s 110m hurdles, bitterly disappoint
ing adoring home fans.The 25-year-old Athens Olympic and world champion had successful foot surgery in December at the Memorial Hermann-Texas Medical Center in Houston, and had four calcium deposits (钙物质) removed from his right Achilles tendon (跟腱).
He spent the next three months in Houston for rehabilitation and basic training under the guidance of doctors there.
"His recovery is better than we expected. Doctors believe that after three months" rehabilitation and training, he has actually achieved the level of recovery that generally needs four months," Feng said.
Liu will, however, be absent from the ongoing annual Chinese People"s Political Consultative Conference (CPPCC) meeting due to the recovery process. Feng said Liu is paying close attention to the meeting through the Internet, and closely following issues such as athletes" education and life after retirement.
It is the second time Liu has asked for leave from the annual session after being elected to the CPPCC: He did not attend last y
ear"s meeting because he was at a key competition in Spain.小题1:The best title for the passage is _______.

Researchers studied the effects of tranexamic acid （凝血酸）, or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journal Lancet. Doctors found that patients who got TXA had a 15percent lower chance of dying from hemorrhage than those who didn’t get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government.
The drug is commonly used in wealthy countries during elective surgeries(外科手术) to stop bleeding , but isn’t used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection（注射） and would be relatively easy to introduce, even in poor countries, experts said.
Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots （凝块）in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.
For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn’t tested on children , experts said it would almost certainly work with them as well.
小题1:The underlined word” hemorrhage” in Paragraph 2 probably means ________
| A．serious illness | B．heart disease | C．heavy bleeding | D．lack of drug |
| A．It can only be made in England | B．It was only used in operations before |
| C．It is a patented drug | D．It is mainly used in poor countries |
| A．a lot of patients died unexpectedly after using it |
| B．it has no treatment effect on patients |
| C．it can cause blood clots or stroke |
| D．they hadn’t used it on accident victims before |
| A．It is a pity that TXA wasn’t widely used on injured patients before |
| B．Tests have proved that TXA can be used on children |
| C．People between 5 and 45 should be injected with TXA every year |
| D．Accidents are the first leading cause of death worldwide. |
