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 between 1992 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.”

St.Martin’s Press has announced the release of the paperback edition of Picking Cotton, a remarkable true story of what novelist John Grisham calls an “account of violence, rage, redemption(救赎)，and, ultimately forgiveness.”　　The story began in 1987, in Burlington, North Carolina, with the rape of a young while college student named Jennifer Thompson. During her ordeal, Thompson swore to herself that she would never forget the face of her rapist, a man who climbed through the window of her apartment and assaulted her brutally.________(1) When the police asked her if she could identify the assailant(袭击者) from a book of mug shots, she picked one that she was sure was correct, and later she identified the same man in a lineup.Based on her convincing eyewitness testimony, a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms. Cotton’s lawyer appealed the decision, and by the time of the appeals hearing, evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton, an imprisoned criminal named Bobby Poole._______ (2) Jennifer Thompson looked at both men face to face, and once again said that Ronald Cotton was the one who raped her.Eleven years later, DNA evidence completely exonerated(证明……清白) Cotton and just as unequivocally(明确地) convicted Poole, who confessed to the crime. ________(3) “The man I was so sure I had never seen in my life was the man who was inches from my throat, who raped me, who hurt me, who took my spirit away, who robbed me of my soul,” she wrote. “And the man I had identified so surely on so many occasions was absolutely innocent.”_______ (4) Remarkably both were able to put this tragedy behind them, overcome the racial barrier that divided them, and write a book, which they have subtitled “Our memoir of injustice and redemption.”Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly______ (5)”
