Article: 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 , 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 _ 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 Change4Life 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.

Article: Reading poems is not exactly an everyday activity for most people. In fact, many people never read a poem once they get out of high school. It is worth reminding ourselves that this has not always been the case in prefix = st1 /America. In the nine-tenth century, a usual American activity was to sit around the fireside in the evening and read poems aloud. It is true that there was no television at the time, nor movie theaters, nor World Wide Web, to provide _ However, poems were a source of pleasure, of self - education, of connection to other people or to the world beyond one ' s own community. Reading them was a social act as well as an individual one, and perhaps even more social than individual. Writing poems to share with friends and relations was, like reading poems by the fireside, another way in which poetry has a place in everyday life. How did things change? Why are most Americans no longer comfortable with poetry , and why do most people today think that a poem has nothing to tell them and that they can do well without poems? There are, I believe, three factors: poets, teachers, and we ourselves. Of these, the least important is the third: the world surrounding the poem has betrayed us more than we have betrayed the poem. Early in the twentieth century, poetry in English headed into directions unfavor-able to reading of poetry. Readers decided that poems were not for the fireside or the easy chair at night, and that they belonged where other difficult-to-read things belonged. Poets failed the reader, so did teachers. They want their students to know something about the skills of a poem, they want their students to see that poems mean something. Yet what usually occurs when teachers push these concerns on their high school students is that young people decide poems are unpleasant crossword puzzles.

Article: A new study warns that about thirty percent of the world's people may not have enough water by the year 2025. An American organization called Population Action International did the new study. It was more than three hundred and thirty-five million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or in the Middle East. Population Action International researcher Robert Engelman says by the year 2025, about three thousand million people lack water. At least 18 more countries are expected to have serious water problems. The demand for water keeps increasing. Yet the amount of water on the earth the same. Mr Engelman says the population in countries that lack water is growing in these countries will continue to increase. The report says lack of water in the future may result several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because of diseases such as cholera that are carried in water. Lack of water also may result in more international conflict. Countries may have to fight for water in the future. Some countries, such as Syria, Sudan, Cambodia, and so on, now get sixty percent of their fresh water from other countries. And the report says lack of water would affect the ability to improve their economies. This is because industries often need a large amount of water. The Population Action International study gives several ways to solve the water problem. One way is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third is to use less water for agriculture. The report also says long-term solutions to the water problem must include controls on population growth.
