Don't you just hate it when you have to take an important phone call and you're surrounded by potential eavesdroppers(潜在偷听者)? You either have to whisper or go outside to keep the conversation private, which is not good. Now Hushme aims to fix this problem by muffling your voice and making you look like Bane in the film Batman.

    Hushme is a strange high-tech mask(口罩)that blocks the sound of the wearer's voice so that people nearby can't hear what is being said. It connects to your phone via Blucetooth and comes with a pair of earphones. When you get a private call, all you have to do is put the mask on and it will do the rest. The pair of thick pads over your mouth does a good job of muffling your voice, but to ensure nothing gets through. Hushme also has speakers that play a variety of sounds when you speak.

    The Hushme mask, which comes in a variety of colors, can be worn around the neck, like a regular pair of earphones, and attaches in front of your mouth thanks to a couple of very powerful magnets(磁铁). It's not yet clear how comfortable speaking with this Bane-like mask over your mouth really is, or how effective its speech muffling ability is, so we know so far is that it makes you look strange. The sound choices for covering your voice currently include wind, ocean, rain, birds, monkey, but new ones could be added in the future.

    Advertised as the “world's first voice mask for mobile phones'. Hushme was showed at CES. At the becoming of this year. Its makers plan to sell it by the end of this year. It will cost about $200.

    If your dog looks pleased to see you—it is probably because it loves the particular way you smell.

    The scent (气味)of a familiar human apparently lingers like perfumein the animal's brain—where it causes an instinctive emotional response, research reveals.

    Our scent acts on a part of the canine (犬科的) brain associated with reward and the strongest reactions are produced by humans that pets know best, say scientists in America.

    Gregory Bern, of Emory University in Atlanta, said, “While we might expect that dogs should be highly tuned to the smell of other dogs, it seems that the 'reward response' is reserved for their humans. When humans smell the perfume of someone they love, they may have an immediate, emotional reaction that's not necessarily cognitive (认识的). So is it in dogs. But since dogs have a more sensitive smell than humans, their responses would likely be even more powerful than the ones we might have. In our experiment, however, the owners of the dog were not physically present. The canine brain responses were being caused by something distant in space and time. It shows that dogs' brains have these mental representations of us that persist when we're not there.”

    The experiment involved 12 dogs of various kinds by brain scans while five different scents were placed in front of them. The scent samples (样本)came from the subject (接受试险者) itself, a dog the subject had never met, a dog living in the subject's household. The familiar human scent samples were taken from someone else from the house other than the handlers during the experiment, so that none of the scent donors were physically present.

    The results showed all five scents gained a similar response in parts of the dogs brains involved in detecting smells. Responses were significantly stronger for the scent of familiar humans, followed by that of familiar dogs. The findings showed dogs reacted strongest to the scent of familiar humans even when they were not there. Pets trained as help or therapy dogs showed greater brain activity than the other dogs in the test.

    Researchers say the findings could improve the way to select animals helping wounded old soldiers or disabled people.

    Lemurs are cute animals that live on the island of Madagascar, the fourth-largest island in the world. Lemurs have big eyes, long noses, and long tails(except for the Indri) and live high in the trees of Madagascan forests. Lemurs are quite intelligent. They are the cousins of monkeys and look quite similar. They also swing through the trees and live in family groups.

    There are different species of lemurs. Some lemurs (the Indri) sing like a whale, and some (the Sifaka) walk like a ballet dancer. Some lemurs are very small, like the Pygmy Mouse Lemur which weighs only 25-30 grams. Others, like the Indri, can weigh up to ten kilograms. Some lemurs are nocturnal, being awake at night and sleeping during the day, and some are not nocturnal but diurnal. Generally, the smaller lemurs are nocturnal, while the bigger ones are diurnal. All the species are unique to Madagascar.

    However, all of the lemurs are endangered species. Many species have already disappeared in the last few centuries. There are not many of lemurs left. People in Madagascar have been destroying the forests where lemurs live. Local people also hunt lemurs for food. Some of the local people see lemurs as bringers of bad luck, so they kill lemurs.

    At the moment, there are about 85 lemur species left. But many people fear that the number of species will fall quickly. Soon there may be no lemurs left if we do not make serious efforts to protect them.

    In my mind, there is a moving story about a skinny young boy who loved football with all his heart.

    Practice after practice, he eagerly gave everything he had. But being half the size of the other boys, he got absolutely nowhere. Despite his hard training at all the games, this hopeful athlete sat on the bench and hardly ever played.

    This teenager lived alone with his father, and the relationship between the two of them was very special. Even though the son was always on the bench, his father was always in the stands cheering. He never missed a game. This young man was still the smallest of the class when he entered high school. But his father continued to encourage him.

    The young man loved football and was determined to try his best at every practice, and perhaps he'd get to play when he became a senior. All through high school he never missed a practice nor a game but remained a benchwarmer. Besides, his faithful father was always in the stands, always with words of encouragement for him. When the young man went to college, he decided to try out for the football team as a "walk-on". Everyone firmly believed that he could never make the cut, but he did.

    The news that he had survived the cut thrilled him so much that he rushed to the nearest phone and called his father. His father shared his excitement and was sent season tickets for all the college games. This persistent young athlete never missed practice during his four years at college, but actually he never got the real chance to play in a game.

    It was at the end of his senior football season that the coach met him with a telegram. The young man read the telegram and he became totally silent. Swallowing hard, he mumbled to the coach, "My father died this morning. Is it all right if I miss practice today? "The coach put his arm gently around his should and said, "Take the rest of the week off, son. And don't even plan to come back to the game on Saturday."

    Saturday arrived, and the game was not going well. In the third quarter, when the team was ten points behind, a silent young man quietly slipped into the empty locker room and put on his football gear. As he ran onto the sidelines, the coach and his players were surprised to see their faithful teammate back so soon. "Coach, please let me play. I've just got to play today, "said the young man. The coach pretended not to hear him. There was no way he wanted his worst player in this close play-off game. But the young man insisted, and finally feeling sorry for the kid, the coach gave in. "All right," he said. "You can go in. ''Before long, the coach, the players and everyone in the stands could not believe their eyes. This little unknown, who had never played before, was doing everything right. The opposing team could not stop him. He ran, passed, blocked, and tackled like a star. His team began to succeed. The score was soon tied. In the closing seconds of the game, this kid got a pass and ran all the way for the winning touchdown.

    Finally, after the stands had emptied, the coach noticed that this young man was sitting quietly in the corner all alone. The coach came to him and said, "Kid, you were unbelievably fantastic! Tell me what got into you? How did you do it? "

    He looked at the coach, tears in his eyes, and said "Well, you knew my had died, but did you know that my dad was blind?" The young man swallowed hard and forced a smile, "Dad came to all my games, but today was the first time he could see me play, and I wanted to show him I could make it!"
