Passage 17

(山东省青岛市2010届高三上学期期中考试)

Guess what? Your dog can get jealous when you pay attention to other dogs, other people or even other things.

Dogs have complex 　36　 　such as jealousy (嫉妒) and pride, according to a scientific research that throws new 　37　 　on their relations with 　38　 .

Behavior experts recommend owners keeping their dog's 　54　 　as much as possible from a new partner or child . This helps to 　55　 　jealous activity from the dog such as interruptions with barking or whining　 (哀嚎).
