What’s the first thing that you notice when you walk into your favorite restaurant? Is it the smell of fresh pizza, or the sight of your favorite desserts? Food that looks and smells good will probably taste good, but what about sound? Is that important?
Scientists now believe that the taste of food can change when your ears hear different sounds, but it has to be the right kind of sound. When you turn on a microwave with popcorn in it, it soon starts to pop. Do you think “That sounds tasty!”? Not really, you probably think it’s nearly ready. But when smell it, you go to get the salt and the butter. Hearing the popcorn make you think about it, but smelling it tells you that it tastes good. So what are the sounds to change the tastes of the things?
In an experiment in a fish restaurant, customers listened to the sound of the seaside while they were eating. Did it make a difference? Yes, it did. Listening to the seaside seemed to improve the taste of the food. It was fresher and saltier. When the restaurant tried the same experiment with the sound of the farm animals, there was no difference in taste. The results are going to be useful for restaurants. Perhaps they will try to use fewer unhealthy things, like salt and sugar in food. With the right music or sounds, perhaps we won’t taste the difference.
Restaurants are also setting a connection between food and the sound that the packet(包装袋) makes. Pick up a packet of your favorite potato chips, what does it sound like? One restaurant recently changed the material that they used to make their potato chip packets because experiments show that the packet which makes a right sound will make customers think the potato chips are fresher. Another idea is that a list of music will begin to appear on food packets, so if you don’t like your green vegetables, the right music or sounds could help you learn to love them.

While he was playing with his toy car, Tom found his mother crying. He ran to her and wiped the tears on her face with his little dirty hands, saying, “I won’t play with the toy any more and I’ll be a good boy.”
After a while, he asked his mom, “Why are you crying?” “Because I am a mother, boy,” she told him.
“I don’t understand,” he said. His mom took him in her arms and said, “You will never.”
Later, the little boy asked his father about it. “All mothers cry for no reason,” answered his father.
The little boy grew up and became a man, still wondering why mothers cry. One day while he was reading a story, he happened to find the answer. In the story, a lovely girl asked a granny, “Granny, why do mothers cry so easily?”
Granny said, “You see, girl, mothers are born to be special. Mothers’ shoulders are strong enough to carry the weight of the world, yet soft enough to give comfort. Their hearts are kind enough to stand the misunderstanding which comes from their children. Mothers take care of their families without saying anything. They love their children, even when their children hurt them badly. This kind of great love makes a child who made mistakes feel better, and it helps mothers share a teenager’s worries and fears.

Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend’s house or in a hotel room, and find it difficult to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be other reasons.
According to a new study published in Current Biology, a significant reason is what the scientists call “first night effect”. They believe that one side of the brain acts as a “night watch” to warn us about potential (潜在的) dangers. It forces us to stay awake on the first night in a new environment.
For the study, 35 young volunteers were told to sleep in a lab for several days. Meanwhile, researchers watched their brain activities.
According to the researchers, on their first night, the left brains were more active than the right brains and people had a hard time sleeping. However, left-brain activity reduced as days went by, falling even to the point of complete calm. In this process, the volunteers got an increasingly better sleep experience.
The findings suggest that the different rhythms (节奏) of the sides of the brain influence our sleep. When the two sides work differently, the balance between them is broken. Thus, the brain can’t relax and is sensitive to anything strange in the surroundings, just as it is in the daytime.
“At some level, the brain is continuing to analyze(分析) things, even though you don’t realize the analysis,” US professor Jerome Siegel told Smithsonian Magazine. “If something unusual happens – if a door opens or you hear a key in a lock – you can be alert (警惕的).”
More surprisingly, this situation is similar to the way some animals sleep. Whales, dolphins, and many birds can sleep with half of their brain while the other half stays awake.
If you have ever had what you think is “first night effect”, researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.
