People who smoke could lose around one third of their daily memory, researchers say.

A study by a team at Northumbria University showed that smokers lost more of their memory when compared to non-smokers.

And the research also found that those who kicked the habit saw their ability to recollect information restored to almost the same level as non-smokers.

The study involved more than seventy 18-to-25-year-olds and included a tour of the university’s campus. Those who took part were asked to recall small details, such as a list of songs played at a campus concert and tasks completed at various points－known as real world memory test. Smokers performed badly, remembering just 59 percent of tasks. But those who had given up smoking remembered 74 percent and those who had never smoked recalled 81 percent of tasks.

Dr. Tom Heffernan, who leads Northumbria University’s Collaboration for Drug and Alcohol Research Group, said the findings would be useful in anti-smoking campaigns. He said, “Given that there are up to 10 million smokers in the UK and as many as 45 million in the United States, it's important to understand the effects smoking has on everyday cognitive（认知的）function-of which prospective memory is an excellent example. ”

“This is the first time that a study has set out to examine whether giving up smoking has an impact on memory. We already know that giving up smoking has huge health benefits for the body, but this study also shows how stopping smoking can have knock-on benefits for cognitive functions too. ’’

The research will now investigate the effects of passive smoking on memory, while Dr. Heffernan and Dr. Terence O’Neil will look into the effects of third-hand smoking－toxins left on curtains and furniture.

【小题1】The couple a_________ a child last year , so they do not feel lonely now.

【小题3】As we all know, smoking has a harmful e__________ on all of us.
【小题4】Father is strongly o________ to doing shopping on Sunday because the streets and supermarkets are full of people. Therefore, we all have to stay at home.
【小题5】He worked hard day and night and e____________ he achieved his aim.

LONDON (AP) — England joins on Sunday the growing list of places that ban smoking in public buildings, taxis and other places including even Buckingham Palace with a tough law.
Pubs, clubs and restaurants will all be smoke-free. Taxi and delivery drivers have been warned that they too could be fined 50 pounds, or about $100, if caught lighting up inside work vehicles.
Experts say the bans have become an irreversible (不可逆转的) tread because of greatly rising health costs and public uneasiness over second-hand smoke. Some of the strictest smoking bans are in the United States, even though there is no federal anti-smoking policy. New York and Florida have strict bans, while California has certain outdoor smoking bans.
Spain, Italy, Iran, Norway, Sweden, Singapore, South Africa, Uruguay and new Zealand have passed legislation(立法) to restrict smoking. France banned smoking in many public places in February and plans to extend the ban to cafes and restaurants next year. Finland is introducing a ban in 2009.
Despite the spread of bans, the World Health Organization predicts a steady rise in tobacco sales. In its Tobacco Atlas, the WHO said that by 2030 there will be “at least another two billion smokers in the world” and an expected decrease in male smokers “will be offset by an increase in female smoking rates, especially in developing countries.”
In advance of the English ban, anti-smoking ads have coated bus stops and the British government has subsidized(资助) programs to help people quit. The rest of Britain—Scotland, Wales and Northern Ireland —already have smoking bans in place.
