Maybe because they can understand our words much better than we thought, according to a study in Hungary. It found that dogs understand not only what we say, but also how we say it. “The results were very exciting and very surprising.” Said the researcher Attila Andies, from Eotvos Lorand University in Budapest. For the study, the researchers first trained 13 dogs for months. The dogs had to sit quietly inside machine, so that the researchers could check their activity. Then the researcher put headphones on dogs and played people’s voice to them. There were four different voice. Some were positive words,such as “well down”, or neutral（不带感彩的） words like “however”. The words were also in different tones（音调）. Some were positive and some were neutral. Brain scans（扫描）showed that the dogs could recognize（辨认）words, as well as the tone of words, much like people do. The positive words with a positive tone brought the stronger activity in their brain’s reward centers（反应中枢）. “It shows that for dogs, a nice phrase can work very well as a prize, but it works best if both words and tones match.” Said Andies. They also found that dogs deal with meaningful words with the left side of the brain and tones with the right. Human brains work in the same way. It gave us a new understanding of language,said Andies. That is, not only do humans understand the meaning in words, other species（物种）do too. 根据短文内容，选择最佳选项，并在答题卡上将选定的答案字母标号涂黑。 1．What was found according to the study in Hungary _____ A．Dogs can’t understand people words.
