While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner. Which of the following statements is TRUE? A) The dogs were not all provided with the entire face, B) According to their size, the dogs were given either upper or lower halves. C) The dogs could read even small changes that accountancy facial expressions after some training. D) The dogs couldn't read strangers facial emotions.

People often talk as if shyness is a disease or mental condition that can be cured. I prefer to think of it as an emotional disability. It's something we are born with and something we carry with us in our entire lives. There are too many people, however, who seem to be determined to find some way of doing away with their shyness. In my opinion, it's a waste of time. I don't mean that we should do nothing about it; quite the contrary, I think we need to separate the basic fact of our shyness from our ability to take part in a social environment. Look at one of the most famous shy people of them all, Johnny Carson. This man is painfully shy, yet for decades he made a living talking and associating with different people every night, in front of a national audience. Carson has never done away with his shyness, but he has successfully found a way to deal with it to the extent that he could be, not just a talk show host, but a legend among talk show hosts. Look also at Sally Fields, who has recently admitted her problem with shyness. This is a woman who has appeared in many films, TV shows and interviews, yet in her early years she was so shy that she turned down a lunch invitation from Jane Fonda because she was terribly afraid of meeting her. I guess that our shyness is there because each of us is born with some insecurity and this insecurity prevents us from reaching out to others the way people with a more open personality do. As we grow up and become adults, we allow our social skills to grow and develop. But we are still stuck in kindergarten or elementary school or wherever it was when our shyness took root in our soul. The passage tells us that Sally Fields was _ . A) proud all the time B) close to Jane Fonda C) impolite when young D) shy in her early years

Ques: Is it okay to keep exercising when you have a cold? What about the flu? With winter viruses going around, it's important to know how to alter your training if you do catch a germ or two. "The guidelines are pretty easy," says Dr Lorenzo Masci from the Alphington Sports Medicine Clinic. "Anything above the neck --- so if you've got a cold for example, a runny nose or a sore throat --- then you should probably cut down your exercise by half and do 50 percent of what you normally do." "If you've got anything below the neck, like muscle pain, joint pain or fever, you shouldn't really exercise at all until those general symptoms settle down," Lorenzo says. He points out that a cough would also fall into this more serious category. "For example, if anyone comes in with a fever and a runny nose, I'd tell them to stop exercising until the fever and the muscle ache settles. Then they can start their training again at 50 percent once all those symptoms settle, even if they've got a bit of a runny nose or a sore throat." "The reason we tell people to stop exercising is because if you exercise when you're unwell it can make the illness worse and prolong it." There is a second reason Lorenzo advises his patients to stop exercising when they have "below the neck" symptoms. In the event you have an illness which affects your heart, exercise can sometimes actually lead to death. Lorenzo advises to take zinc and vitamin C as a way of preventing colds. But he admits that this is controversial --- some studies have shown that these supplements can improve immune function while other studies have cast doubt on the issue. The good news is that if you exercise regularly, you're likely to improve your immune function. "If you exercise too much, it can predispose you to coughs and sniffles," he points out. This is often the case for excellent athletes who train every day, such as triathletes . "But what we do know is that if you exercise at a moderate level, your immune system improves such that you're probably at a lower risk... How should people do exercises with a fever or a cough? A) They should probably reduce their training time by 50%. B) They should stop exercising until they recover. C) They should start exercising at 50% after their runny nose settles. D) They should do half of what they normally do.
