2,Ross's statement leaves open the possibility that the cause he cites came after the effect he attributes to it.(同上,读不懂)
3,The occupations of county residents affect their risk of exposure to mosquito-borne encephalitis more than dose television watching.(这个句子的意思是不是:这个县的居民的职业对他们得脑炎风险的影响比看电视引起的大?)。。。职业更容易引发脑炎???
