While dog keepers realize their dogs can read their moods accurately, scientists have always been a little 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 exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That’s because the scientists believe humans show their emotions on their entire face.
After some training like 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 rewarded, the trepidation seemed 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 touchscreen 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 same gender as their owner.

Manners nowadays in big cities like London are particularly non-existent. It's nothing for a big, strong schoolboy to push an elderly woman aside in the dash for the last remaining seat on a bus, much less stand up and offer his seat to her, as he ought to. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly always one from the older generation.
This question of giving up seats in public transport is much argued by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it's not agreed, however, that young men should stand up for older women, the fact remains that courtesy should be shown to the old, the sick and the burdened. Are we really so lost to all ideals of unselfishness that we can sit there indifferently reading the paper or a book, saying to ourselves "First come, first served", while a gray-haired woman, a mother with a young child or a cripple stands? Yet this is too often seen.
Older people, tired and easy annoyed from a day's work, aren't angels, either-far from it. Many an argument or an insulting quarrel breaks out as they feel tired of pushes in the queue and shove(猛推) each other to get on buses.
If cities are to remain pleasant places to live in at all, however, it seems necessary, not only that communication in transport should be improved, but also that communication between human beings should be kept smooth and polite. Shop assistant won't bother to assist, taxi drivers shout at each other as they dash dangerously round comers, bus conductors pull the bell before their desperate passengers have had time to get on or off the bus, and so on. It seems to us that it's up to the young and strong to do their small part to stop such deterioration(恶化).

A. A big strong schoolboy never pushes the elderly for a seat on a bus.
B. Young persons are sure to offer seat to the elderly.
C. Older generation have better manners than the young.
D. Elderly women are often treated politely.
2.What's the author's attitude towards the young men's argument about offering seat in public?
A. Tolerant. B. Doubtful. C. Positive. D. Negative.
3.What do we know about older people when they are tired from a day's work?
A. Older people behave worse than the young.
B. Older people may also have unpleasant behaviors.
C. Older people don't like taking buses.
D. Older people are good at argument and quarrel.
4.Why does the author write this article?
A. To tell us that manners nowadays in big cities are non-existent.
B. To scold the persons who have no manners at all.
C. To warn us of the seriousness of young men's lacking good manners.
D. To call on the young to improve the situation.

I once bought the beautiful bracelet from a store and felt excited when I tried it on. Sadly, I was soon disappointed at that my naughty kids broke it. But instead of just feel sad, I chose to repair it myself.
To my greatly surprise, it didn’t take a long time to do it. As time went by, I found that I was not happy with just repairing my breaking bracelets. I started making new bracelets out the materials from my old one. Later on, I begin to design on my own
Then I made my first deal. Back in 2013, I posted my bracelets on WeChat for the first time and several friends said that they wanted it. That was just the start. With much materials at hand, I made my designs into reality.
I can well remember that I was once asked to deliver a speech titled “A Real Test in My Life” before the whole class at the age of 9! You can imagine how1.(terrible) shy I was with so many eyes fixed on me. I had no choice but 2.(prepare) for it, though. First of all, I was to draft the speech, 3. was just a piece of cake for me, a good writer. But the hardest part 4.(lie) in my oral presentation from my memory—for to read from the paper 5.(forbid). The real moment began when I stood on the platform with my legs 6.(tremble) and my mind blank. But my listeners were waiting patiently without any signs of rushing me. Gradually I found 7. (I) back, delivering my speech without difficulty. After 8. seemed to be a hundred years, I found my audience applauding—I made it! From then on, my fear of talking before the audience disappeared. Actually with my 9.(confident) built up, I now turn out to be a great speaker. Looking back, I know the10.(great) difficulty on our way to success is our fear. Overcome it and we will be able to achieve our goals.
Life is to be lived. No excuses. No reservations (保留). No holding back.
