Australia is a nation of pet lovers but maybe it is loving its pets to death, because pet owners are overfeeding their cats, dogs, etc．, the country’s main animals’ welfare body says．Despite its image as a sports-loving country full of fit and bronzed youth, Australia in reality is battling with obesity and challenging the United States as the world’s fattest nation．The problem now extends to household pets．
Obesity rate of Australia has doubled over the past 20 years, with 62 percent of men and 45 percent of women overweight．The same trend applies to household pets, with an increase in the number of overweight cats and dogs being dealt with by the Royal Society for the Prevention of Cruelty to Animals(RSPCA)．‘It’s a big problem, and quite reflective of what’s happening in the human situation,’ says Mark Lawrie, the RSPCA’s chief vet．Australia is a nation of about 20 million people, almost 4 million dogs, 2.5 million cats, 8.7 million pet birds and more than 12 million pet fish．It has one of the world’s highest rates of pet ownership： 64 percent of households own pets, compared to 62 percent in the United States and 44 percent in Britain．
Lawrie says that surveys have found that between 40 and 44 percent of dogs and more than one in 3 household cats are now overweight, due to overeating and lack of exercise．Fat cats and dogs are much more likely to suffer from heart problems and liver disease．The RSPCA says low levels of exercise has an impact on pet obesity, but the key problem is overeating．

It is certainly a problem to Australians that ________．
Not even Dan Brown and his Da Vinci code-breakers(密码破译者)dared deal with the mystery of Mona Lisa’s smile．But Nicu Sebe, a computer expert at the University of Amsterdam, the Netherlands, did．He used ‘emotion recognition’ software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厌烦的)(9 per cent)．
Faces show emotions．Psychology, computer science, and engineering researchers are joining forces to teach machines to read expressions．If they succeed, your computer may one day“read”your mood．Machines equipped with emotional skills could also be used in teaching, gaming, mind-reading, etc．
“Mind Reader”, a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Technology)in the US, uses input from a video camera to do real-time analysis of facial expressions．It reports on whether you seem“interested” or“agreeable”or if you’re“confused”．The system can help people recognize others’ emotions．Picard says this means we could teach a machine to be as sensitive as a human．In fact, a machine can be even smarter than people since it can tell if a person is lying or just“performing”by analyzing one’s facial movements．
Jeffrey Cohn, a psychologist at the University of Pittsburgh, uses the Facial Action Coding System to recognize human emotions．The system sorts more than 40 action units(AUS)of the face to tell people’s real emotions．He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else．But Cohn saw no real sadness in the woman’s face．
Sadness is a group of AUS that is difficult to do at the same time．You have to pull down the corners of your lips while bringing your eyebrows together and raising them．What the woman did was raise her cheeks to make a lip curl(撇嘴)．Her brows stayed smooth．
