A New Strategy to Overcome Breast Cancer
Post-menopausal（绝经后的）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 there was more evidence that lifestyle influenced cancer risk.
A recent poll for the charity Ramblers found 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 incorporated 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."
Dr.Alpa Patel was______.
A:chief editor of Cancer Epidemiology
B:chair of the American Cancer Society
C:chief executive of Breast Cancer Campaign
D:head of the survey study

Garlic
From early times man has used garlic（大蒜）.The Bible speaks of it. The Israelites
（古以色列人）were once far from home. They cried out to Moses, their leader, for the
foods they loved: leeks（韭菜）,onions and garlic. The Romans , like the Israelites,
loved to eat garlic.And they hung bags of garlic around their necks.________(1)
They also thought it would keep them from getting sick.
A similar idea is still held.Many people take garlic thinking it will prevent or cure
disease .Most doctors say it does no such thing.________(2)Its smell may force
people to stay far apart.At least then they can't pass germs on to each other.
________(3)What if you're in a play,for instance?Actors have been known to
forget their lines because they couldn't stand the garlic smell on a fellow actor's breath.
Some have even made up new lines and actions that kept them far away from the one who
had eaten garlic.
Through the years man has tried to cope with the smell of garlic.________(4)
We now know why .It's been found that the oils of the garlic do not stick to the teeth,
tongue,or gums（齿眼）.They go into the lungs instead.From there they are breathed
out.They pass out through the skin too.
Strange as it seems,food may have a great deal of garlic in it without smelling or
tasting strong .It all depends on how it is cooked.French cooks make a good soup with
whole cloves（瓣）of garlic.They use more than thirty cloves in one bowl of soup.But
they take care not to crush them .And they cook them whole._______(5)And as
the cloves cook they change in some strange way.The soup turns out to be delicious.It's
not strong at all.
________（3）
A:But no medicine,mouthwash,chewing gum,or toothpaste seems to help much,
B:As a result,the strong oils stay in the cloves.
C:They say it may help in one way,though.
D:Many people eat garlic.
E:But keeping your distance can be hard at times.
F:They hoped it would keep away the evil eye.
