A New Strategy to Overcome Breast Cancer Post-menopausal (绝经后) women who walk for an hour a day can cut their chance of breast cancer significantly, a study has suggested. The report, which followed 73,000 women for 17 years, found walking for at least seven hours a week lowered the risk of the disease. The American Cancer Society team said this was the first time reduced risk was specifically linked to walking. UK experts said it was more evidence that lifestyle influenced cancer risk. A recent poll for the charity Ramblers a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers. This study, published in Cancer Epidemiology, Biomarkers & Prevention, followed 73.615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between1992 and 1993, so it could monitor the incidence of cancer in the group. They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking, swimming and aerobics(有氧运动)and how much time they spent sitting watching television or reading. They completed the same questionnaires at two-year intervals between 1997 and 2009.Of the women, 47%said walking was their only recreational activity. Those who walked for at least seven hours per week had a 14% lower risk of breast cancer compared to those who walked three or fewer hours per week. Dr. Alpa Patel, a senior epidemiologist at the American Cancer Society in Atlanta, Georgia, who led the study, said:‖Given that more than 60% of women report some daily walking, promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women. We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women.‖‖More strenuous(紧张的)and longer activities lowered the risk even more.‖ Baroness Delyth Morgan, chief executive of Breast Cancer Campaign, said: ―This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporate into our normal day-to-day activity can make a difference.‖ She added:‖We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place. The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer. All of the following factors relating to cancer risk were mentioned in the EXCEPT（）

The Storyteller 1.Steven Spielberg has always had one goal: to tell as many great stories to as many people as will listen.And that’s what he has always been about.The son of a computer scientist and a pianist, Spielberg spent his early childhood in New Jersey and, later, Arizona.From the very beginning, his fertile imagination filled his young mind with images that would later inspire his filmmaking. 2.Even decades later, Spielberg says he has clear memories of his earliest years, which are the origins of some of his biggest hits.He believes that E.T.is the result of the difficult years leading up to his parent’s 1966 divorce, “It is really about a young boy who was in search of some stability in his life.”“He was scared of just about everything,” recalls his mother, Leah Adler.“When trees brushed against the house, he would head into my bed.And that’s just the kind of scary stuff he would put in films like Poltergeist.”3.Spielberg was 11 when he first got his hands on his dad’s movie camera and began shooting short flicks about flying saucers and World War ΙΙ battles.Spielberg’s talent for scary storytelling enabled him to make friends.On Boy Scout camping trips, when night fell, Spielberg became the center of attention.“Steven would start telling his ghost stories,” says Richard Y.Hoffman Jr., leader of Troop 294, “and everyone would suddenly get quiet so that they could all hear it.”4. Spielberg moved to California with his father and went to high school there, but his grades were so bad that he barely graduated.Both UCLA and USC film schools rejected him, so he entered California State University at Long Beach because it was close to Hollywood.Spielberg was determined to make movies, and he managed to get an unpaid, non-credit internship(实习)in Hollywood.Soon he was given a contract, and he dropped out of college.He never looked back.5. Now, many years later, Spielberg is still telling stories with as much passion as the kid in the tent.Ask him where he gets his ideas, Spielberg shrugs.“The process for me is mostly intuitive (凭直觉的),” he says.“There are films that I feel I need to make, for a variety of reasons, for personal reasons, for reasons that I want to have fun, that the subject matter is cool, that I think my kids will like it.And sometimes I just think that it will make a lot of money, like the sequel(续集) to Jurassic Park.” Spielberg says he makes movies for（）
The National TrustThe National Trust in Britain plays an increasingly important part in the preservation for public enjoyment of the best that is left unspoiled of the British countryside. Although the Trust has received practical and moral support from the Government, it is not a rich Government department. It is a voluntary association of people who care for the unspoiled countryside and historic buildings of Britain. It is a charity which depends for its existence on voluntary support from members of the public'. Its primary duty is to protect places of great natural beauty and places of historical interest. The attention of the public was first drawn to the dangers threatening the great old houses and castles of Britain by the death of Lord Lothian, who left his great seventeenth-century house to the Trust together with the 4500-acre park and estate surrounding it. This gift attracted wide publicity and started the Trust's "Country House Scheme‖. Under this scheme, with the help of the Government and the general public, the Trust has been able to save and make accessible to the public about one hundred and fifty of these old houses2. Last year about one and three quarters of a million people paid to visit these historic houses, usually at a very small charge. In addition to country houses and open spaces the Trust now owns some examples of ancient wind and water mills, nature reserves, five hundred and forty farms and nearly two thousand five hundred cottages or small village houses, as well as some complete villages. In these villages no one is allowed to build, develop 'or disturb the old village environment in any way and all the houses are maintained in their original sixteenth-century style. Over four hundred thousand acres of coastline, woodland, and hill country are protected by the Trust and no development or disturbances of any kind are permitted. The public has free access to these areas and is only asked to respect the peace, beauty and wildlife. So it is that over the past eighty years the Trust has become a big and important organization and an essential and respected part of national life, preserving all that is of great natural beauty and of historical significance not only for future generations of Britons but also for the millions of tourists who each year invade Britain in search of a great historic and cultural heritage. The National Trust is dedicated to（）
