158,（卫生健康,社会/论断/——）The Trash-Site Safety Council has recently conducted a statewide study(5) of possible harmful effects of garbage sites on the health of people living near the sites.A total of five sites and 300 people(1) were examined.The study revealed,on average,only a small statistical correlation between the proximity of homes to garbage sites and the incidence of unexplained rashes(2) among people living in these homes.Furthermore,although it is true that people living near the largest trash sites had a slightly higher incidence of the rashes,there was otherwise no correlation between the size of the garbage sites and people's health(4).Therefore,the council is pleased to announce that the current system of garbage sites does not pose a significant health hazard(3).We see no need to restrict the size of such sites in our state or to place any restrictions(6) on the number of homes built near the sites.
159,（社会/建议/对比）The nation of Claria covers a vast physical area.But despite wide geographic differences,many(1) citizens are experiencing rising costs of electricity.A recent study of household electric costs in Claria found that families who cooled their houses with fans alone spent more on electricity than did families using air conditioners alone for cooling.However,those households that reported using both fans and air conditioners spent less(3) on electricity than those households that used either fans or air conditioners alone(2).Thus,the citizens of Claria should follow the study's recommendation and use both air conditioners and fans in order to save money on electricity(4).
