Ⅰ.阅读理解
(2016·江西九校联合测试)导学号 42492609
More than 4 in 10 cancers—600,000 in the UK alone—could be prevented if people
led healthier lives, say experts.The population of the UK is about 63,000,000.
Latest figures from Cancer Research UK show smoking is the biggest avoidable risk
factor (因素), followed by unhealthy diets.The charity advises people to live
healthily, limit alcohol intake and do regular exercise.
According to the figures from 2007 to 2011, more than 300,000 cases of cancer
recorded were linked to smoking.A further 145,000 were linked to unhealthy diets
containing too much processed food.Obesity contributed to 88,000 cases and alcohol
to 62,200.Sun damage to the skin and physical inactivity were also contributing
factors.
Professor Max Parkin, a Cancer Research UK statistician, says, “There's now
little doubt that certain lifestyle choices can have a big influence on cancer risk,
with research around the world all pointing to the same key risk factors.”
“Of course everyone wants to enjoy some extra treats during the Christmas
holidays so we don't want to ban beef pies and wine but it's a good time to think
about taking up some healthy habits.”
“Leading a healthy lifestyle can't guarantee someone won't get cancer but
we_can_stack_the_ odds_in_our_favour by taking positive steps.”
Public Health England says a healthy lifestyle can play an important role in
reducing cancer risk.It says campaigns such as Smokefree, Dry January and Change Life
Sugar Swaps all aim to raise public awareness.It's important that we not only continue
to make progress in noticing cancer earlier and improving treatments, but helping
people understand how they can reduce their risk of developing cancer in the first
place remains important in dealing with cancer.

让每个人平等地提升自我
3 countries.__1.A__In general, they can expect to live six or seven years more than
men.One reason for this is biological.
One important biological factor that helps women live longer is the difference
in hormones between men and women.__2.G__ Between the ages of about 12 and 50, women
produce hormones that are involved in fertility(生育能力)．These hormones also have
a positive effect on the heart and the blood flow.In fact, women are less likely to
have high blood pressure or to die from heart attacks.
__3.D__They help the body defend itself against some kinds of infections.This
means that women generally get sick less often and less seriously than men.The common
cold is a good example：women，on average，get fewer colds than men.
__4.C__Scientists are still not exactly sure how genes influence aging，but they
believe that they do.Some think that a woman's body cells have a tendency(倾向)to
age more slowly than a man's.Others think that a man's body cells have a tendency
to age more quickly.__5.E__
A．However，women，on average，live longer.
B．The biological factor plays an important part.
C．Women are also helped by their female genes.
D．The female hormones also protect the body in another way.
E．Recent research seems to support both of these possibilities.
