答案

Dogs wag their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back,a study has found.研究发现,狗朝什么方向摇尾巴取决于他们是否兴奋,想要前进,还是受到威胁,想要后退.Researchers in Italy examined the tail wagging behaviour of 30 dogs,catching their responses to a range of stimuli with video camems.To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years.The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari Umversity.意大利的研究人员研究了30条狗的摇尾巴的行为方式,并用录象机捕捉他们对一系列刺激的反应.为了开展研究,他们选择了一至六岁阶段的15条公狗,15条母狗.这些狗全部都是家庭宠物,他们的主人许可他们参与BARI大学的研究实验.The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli.They were tested one at a time.这些狗被放在一个前端有个开口的大木箱中,通过开口他们可以看到各种刺激.测试时每次一条狗.The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive expenence—their tails wagged energetically to the right side.When they were shown an unfamiliar human they wagged to the right,but with somewhat less enthusiasm.由Trieste大学Giorgio Vallortigara 教授牵头的研究人员发现:当他们向主人有积极的表现时,会向右摆尾.当他们见到生人时,也会向右摆尾,只是不再那么热情.The appears of a cat again caused a right-hand side wag,although with less intensity again.The appearance of a large unfamiliar dog,similar to a German shepherd,changed the direction of tail wagging to the left.Research ers supposed the dog was thinking of moving back.When the dogs were not shown any stimuli they tended to wag their tails to the left,suggesting they preferred company.看到猫也会让狗向右摆尾,虽然他们不太热情.看到一条不太熟悉的大狗,如一条德国牧羊犬,他会将摆尾方向转为左.研究人员认为他当时正想后退,当狗没有受到刺激时,他们会向左摆尾,表明他们更喜欢同伴.While the changes in the tail wagging were not easily noticed without the aid of video,it was thought that the findings could help people judge the mood of dogs.Computer and video systems,for example,could be used by professional dog trainers to determine the mood of dogs that they were required to approach.若没有录象的帮助,摇尾的变化不易为人注意到,有人认为,这一发现有助于帮助人们判断狗的情绪.专业的训狗人员可以利用电脑系统判断他们想要接触的狗的情绪.
