Television watching is an activity which is known to be harmful to health and is distinct from getting too little exercise．But a new study suggests its damaging effects may even 1 alongside those from smoking and obesity(肥胖)．Researchers who studied television viewing habits in Australia calculated that people who watch for a(n) 2 of six hours a day shorten their lift, expectancy(预期寿命)by almost five years．
They based their calculations on data on the 3 between television viewing and death from the Australian obesity and lifestyle study which involved l 1,000 adults aged 25 and over．Applying these findings to the whole population over 25, who are estimated to have watched 9．8 billion hours of TV in 2008, they concluded that it 4 for 286,000 years of life lost－equivalent to 22 minutes for each, hour watched．By 5 , smoking one cigarette is estimated to shorten life expectancy by 11 minutes－equivalent to half an hour of TV watching．
Writing in the British Journal of Sports Medicine, the authors from the University of Queensland, say the figures suggest "huge loss of life may be 6 with too much TV viewing．" The UK and other industrialized countries are likely to be similarly affected "given the typically large amounts of time spent watching TV and the similarities in disease patterns．" The researchers add："If these figures are 7 and shown to reflect a cause and effect relationship, TV viewing is a public health problem comparable in size to established behavioral risk factors．"
Researchers from Taiwan University found even those who did as little as 92 minutes' exercise a week, －equivalent to 15 minutes a day for six days a week－reduced their 8 of death by 14 per cent．Even this small amount of exercise could postpone one in six of all deaths－similar to the effects of a stop-smoking programme．Each 9 15 minutes a day reduced the death rate by a further 4 per cent．

So long as teachers fail to distinguish(区别, 辨认) between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that“ reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public observation.
If teacher and learner roles are not interchangeable ,what then can be done through teaching that will aid the child in the quest（探索）for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children. ”
When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them properly, then much of the pressure and feeling of failure for both is eliminated(除去, 剔除). Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.
