　　ACABB1.这是一道细节判断题。根据最后一段“Whilethechangesinthetailwaggingwerenoteasilynoticedwithouttheaidofvideoitwasthoughtthatthefindingscouldhelppeoplejudgethemoodofdogs.”可以推断出如果没有摄像机的帮助，人们很难发现狗尾巴摇动的变化，所以摄像机是使得观察更加容易。2.这是一道词义猜测题。第三段是几个排比的句子，画线词和前面的“energetically”和“enthusiasm”都是同义词。3.这是一道细节判断题。根据第三段“Whenthedogswerenotshownanystimulitheytendedtowagtheirtailstotheleft...”可知没有刺激的时候，狗的尾巴是摇向左边的。4.这是一道指代题。根据“Computerandvideosystemsforexamplecouldbeusedbyprofessionaldogtrainerstodeterminethemoodofdogsthattheywererequiredtoapproach.”approach是“接近”的意思，由于是驯狗师被要求接近狗而不能是狗被要求接近驯狗师，所以they指代的是dogtrainers。5.这是一道归纳题。根据最后一段“Whilethechangesinthetailwaggingwerenoteasilynoticedwithouttheaidofvideoitwasthoughtthatthefindingscouldhelppeoplejudgethemoodofdogs.”可以推断出这个研究可以帮助人们判断狗的情绪。
