Directions：Complete the following passage by using the words in the box．Each word can only be used once．Note that there is one word more than you need．

　　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．
