(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　 .

Animal psychologists previously believed most animals lacked "　 39　 　of self", which is needed to experience secondary emotions such as 　40　 , embarrassment or guilt. These emotions are more 　41　 　than instant reactions such as anger or joy.

Professor Friederike Range, from the University of Vienna, has shown that dogs are jealous when they feel unfairly treated　 42　 　to other dogs. "Dogs show a strong 　43　 to inequity (不公平)," she said. "If one dog gets something, you'd better believe another will 　44　 　something as well."

But, her study 　45　 , it doesn't matter if one gets a better treat, only that the distribution is 　46　 .

The dog study is the latest into several 　47　 , including cows, horses, cats and sheep, which have 　48　 　that animals are far more self-aware than 　49　 　were thought.

Paul Morris, a psychologist at the University of Portsmouth who studies animal emotions, told The Sunday Times: "We are learning that dogs, horses, and perhaps many other species are far more 　50　 　complex than we ever realized. They can 　51　 　simple forms of many emotions we once thought only primates (灵长类) could experience."

In research among 　52　 , Morris found almost all of them reported 　53　 　behavior by their pets. The dog often tried to get their owner away from a new lover in the early days of a relationship.

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).
