澳大利亚中小学听力练习之狗和主人脑频一致

　　Dogs make great listeners.

　　狗是最好的倾听者。

　　And that may be because man and man's best friend use analogous brain regions to process voices.

　　而这也许是因为人类和人类最好的朋友都使用类似功能的大脑区域对声音进行处理分析。

　　Researchers collected almost 200 sound samples, including human and canine vocalizations, as well as environmental noises and silence.

　　研究人员们采集了大约200份声音样本，其中包含了人类和犬类的发音，以及环境噪音和静默时的背景声音。

　　They played these clips to 22 people and 11 dogs while the subjects' brains were undergoing functional MRI scans.

　　他们随后对22名人类以及11只狗播放这些音频片断，收听的对象们还在同时进行着大脑功能性核磁共振扫描检测。

　　Human brains tuned in most to vocal sounds.

　　人类大脑对大部分声音都能接收到。

　　Dog brains were most sensitive to environmental noises.

　　而狗的大脑则对环境噪音比较敏感。

　　But they still had a lot in common.

　　但人类和狗类大脑反应还是有许多共同点存在的。

　　A dedicated brain area reacted strongly to the vocalizations of their own species.

　　各自物种的脑类中都有一个专门区域对本类别的发声作出强烈的反应。

　　And that area also responded to the voices of the other species.

　　而该区域也能对其它物种的声音做出反应。

　　Meanwhile, a different brain region noted emotion in a voice, with a strong response to cheery sounds like laughter and a weaker reaction to unhappy noises like canine whining.

　　同时，另外一个不同的大脑区域是通过声音对情感进行了标注的地方，会因为像大笑这种欢呼声有强烈的反应，而对像犬类哀号悲鸣这样的不愉快噪音则没有过强的反应。

　　The study is in the journal Current Biology.

　　该研究已在《当代生物学》杂志上发表。

　　Seems that thousands of years of domestication have made our furry friends sensitive to the same vocal cues we are.

　　貌似几千年的驯化工作使得我们这些有毛的朋友们对一些我们人类所特有的声音特点比较敏感了。

　　You can confide in Fido.

　　你可以相信Fido的。

　　重点讲解

　　1.fall asleep 入睡; 睡着

　　As we fall asleep the amplitude of brain waves slowly becomes greater.

　　进入睡眠状态时，我们的脑电波振幅慢慢变大。

　　After changing the bed, I would fall asleep quickly.

　　换了床单，我很快就能睡着。

　　2.come to 苏醒;达到;来到

　　There are thousands of students absolutely gagging to come to this university.

　　肯定有成千上万的学生都渴望到这所大学念书。

　　I do hope you'll be able to come to the wedding.
