8．More than four in 10cancers-600，000in 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，followed by unhealthy diet．The charity advises people to live healthily，limit alcohol intake and do regular exercise．
According to the figures from 2011to 2015，more than 300，000cases of cancer recorded were linked to smoking．A further 145，000were linked to unhealthy diets containing too much processed food．Obesity contributed to 88，000cases and alcohol to 62，000．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 for 2016．
"Leading a healthy lifestyle can't guarantee someone won't get cancer but we can stack the odds in our favor by taking positive steps．"
Public Health England says a healthy lifestyle can play an important role in reducing cancer risk．It says campaigns such Smokefree，Dry January and Change4Life Sugar Swaps all aim to raise public awareness．It's important that we 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．

解答 25．A．细节理解题．根据第三段more than 300，000cases of cancer recorded were linked to smoking．A further 145，000were linked to unhealthy diets containing too much processed food．Obesity contributed to 88，000cases and alcohol to 62，200．可知可避免的致癌因素中排名第一的是吸烟，第二是不健康的饮食，第三是肥胖，第四是喝酒．故选A．
26．A．细节理解题．根据第五段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 for 2015．可知Max Parkin教授虽然极力倡导健康的生活方式，但他认为节假日期间少量喝酒还是可以的．故选A．
27．D．句意理解题．根据第四段中的There's now little doubt that certain lifestyle choices can have a big influence on cancer risk可知生活方式的选择对得癌症的几率有很大的影响．因此健康的生活方式虽然不能确保我们不得癌症，但可以"降低我们得癌症的几率"．故选D．
28．B．主旨大意题．本文前三段通过数据等说明可避免的致癌因素的前几名都跟生活方式有关，第四、五、六段引用Max Parkin教授的话进一步证明了生活方式与癌症之间的关系，最后一段通过英国公共卫生局的官方发言再一次说明了健康的生活方式可以降低得癌症的几率，因此主要说明了癌症与我们的生活方式有很大的联系．故选B．
