It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.

When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.

Scientists have now shown that pet dogs also have “left gaze bias(左视偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.

Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.

“Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first.”

Millions of British people have ditched the traditional “thank you” and took the place of it with the less formal “cheers”, according to a survey.

Although the common person will say “thank you” nearly 5,000 times a year, one in three are more likely to add a “cheers” or “ta” where it’s needed to show they are fashionable.

One in twenty now say “nice one” instead, while the younger are more likely to offer a “cool” than a “thank you”.

“Merci”, “fab” and even “gracias” were also listed as common phrases to use, as “much appreciated(感激)”.

One in twenty who took part in the survey of 2,000 people by the Food Network UK for Thank You Day, which is marked on November 24, 2011, said a formal “thank you” was now not often needed in everyday conversation. More than one in ten adults said they regularly won’t say thank you if they are in a bad mood. Most people stated that saying thank you was something that their parents trained them. A huge 70 percent of those questioned will say thank you to a person’s face without even meaning it, while one fifth avoid(避免)saying it when they know they should.

It seems our friends and family get the stress of our bad manners. Half of them admit (承认) they’re not good at thanking those closest to them. Many of them explain that they don’t say thank you because their family “already know I’m grateful”.

When spoken words won’t do, it falls to a nice text to do the job for most people.

One third will still send a handwritten thank-you note---but 45 percent admit it’s been more than six months since they tried to send one.

A quarter of British people say “thank you” with food, with 23 percent cooking a meal to show their appreciation to someone. Another 15 percent bake a cake.

It follows that 85 percent of people will be angry because of not getting the gratitude (感激)

they feel they should receive.
