They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants’ skills are more than they are supposed to be.
_________
Speaking of music, babies can’t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music.
To test babies’ dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren’t sure why it becomes weaker later in their life.
Learning Quickly while Sleeping
Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments.
As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said.
Judging Characters Well
Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby’s first step in the formation of morals, Hamlin thought.

About half American teenagers do not get enough sleep on school nights.They get an average of sixty to ninety minutes less than experts say they need.
One reason for this is biology.Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups.Yet many schools start classes as early as seven in the morning.As a result，many students go to class feeling like sixteen?year?old Danny.He is an active teen— except in the morning.“Getting up in the morning is pretty terrible.I’m just very out of it and tired.Through the first and second period I can hardly stay awake,” he said.
Michael Breus is a psychologist.Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night.He says sleepy teens can experience a form of depression(消沉) that could have big influence on their general well being.It can affect not just their ability in the classroom but also on the sports field and on the road.So what can schools do about sleepy students？The psychologist says one thing they can do is to start classes later in the morning.Studies show that students can improve by a full letter grade in their first and second period classes.
Eric Peterson is the head of St.George’s School in the northeastern state of Rhode Island.He wanted to see if a thirty?minute delay(推迟)would make a difference.It did.He says visits to the health center by tired students decreased by half.Late arrivals to the first period fell by a third.And students reported that they were less sleepy during the day.Eric Peterson knows that changing start times is easier at a small school like his.But he is hopeful that other schools will find a way.

Since 1950, the amount of information about the nutrition of food has increased by nearly 900 percent. Besides this fact, obesity has risen by 214 percent and nearly two out of every three adults in America are overweight or obese. Being overweight is not only an appearance problem, and it also increases the risk of various diseases including diabetes, sleep disorder and cancer.
With so much nutritional knowledge easy to find, we cannot simply ignore our present obesity epidemic(流行病). We know that fruits and vegetables are rich in vitamin. Though we are overweight, many of us choose junk food over healthy food out of habits. One explanation for our strong desire for junk food is that we learn to connect junk food with positive feelings when we are young, and changing this attitude requires a huge amount of confidence and determination. Fortunately, new research published in May 2012 has shown a simple and accessible way to make healthier food choices- the one that doesn’t rely on great determination.
The research was based on two separate studies and it was carried out by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. In the first study, 60 adults between the ages of 19 and 23 were questioned about the role of food and drinks. The survey tells us that adults prefer sweetened drinks with high-calorie, salty foods, to sweetened drinks with vegetables.
In the second study, 75 children between the ages of 3 and 5 were gathered for some experiments including drinks served with vegetables. The preschooler experiments were carried out under different situations and on different days. The researchers found that the children chose to take more green vegetables when they were served with water instead of a sweetened drink.
According to Cornwell, children learn to connect high calorie, sugary drinks such as cola, with high fat foods such as French fries, from a very early age. McAlister adds that early taste development appears to play an important role in food choices later in life. Meals served at home and meals offered at restaurants, set the stage for this idea and for the preference to choose junk food over healthy food, when beginning to take sweetened drinks.
“Our taste preferences are heavily influenced by regularly eating particular food and drinking particular drink,” states Cornwell. “If the drink on the table goes against both adults and children eating their vegetables, then perhaps it is time to change that drink… and to serve water with all meals. Restaurants could easily use water as free drink for children’s meals and charge extra money for other drinks.” Both McAlister and Cornwell are confident that serving water with meals could effectively reduce the nation’s obesity rates, diabetes rates and ever rising healthcare costs.

Skateboarding has become one of several non - traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line (滚轮) skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
“Our children and youth are becoming unhealthy and obese,” says Lindsey Johnson. “Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest.”
Some schools don’t allow skateboarding because they say it is dangerous. Cendali, however, argues that regular practice eliminates a great deal of the danger. “We teach students how to do it and how to do it safely,” he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed,” says education expert Richard Sagor of Lewis & Clark College in Portland, Oregon.
Skateboarding inspires kids not to give up in learning difficult skills. “It’s natural for kids to want to learn and get better at things,” adds Sagor. “When it comes to skateboarding, they’ll try a trick hundreds of times before they succeed.” That same effort could be made in schoolwork.
Eric Klassen agrees that skateboarding requires kids to stop saying a task is too hard for them. “A baby will attempt to walk 600 to 900 times before he or she is successful,” says Klassen. “We tell students that they shouldn’t say ‘I can’t do it’ unless they’ve tried 600 to 900 times.”
【小题1】Skateboarding is introduced into American schools to ______.
| A．encourage students to compete bravely in competition |
| B．teach students how to deal with risks |
| C．prevent students suffering from heart disease later in life |
| D．help students form the habit of doing sports |
| A．reduces | B．increases | C．adds | D．brings |
| A．To succeed in life you have to learn skateboarding. |
| B．You will succeed in life if you don’t give up. |
| C．Only after failing 600 to 900 times can you succeed. |
| D．There is no hard work after learning skate-boarding well. |
| A．The dangerous PE | B．Skills of skateboarding |
| C．The new PE | D．The change of PE |

To us it seems so natural to put up an umbrella to keep the water off when it rains, but actually the umbrella was not invented as protection against the rain, Its first use was as a shade against the sun!
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese in the 11th century BC.

By the eighteenth century, the umbrella was used against rain throughout most of Europe.
Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn’t until the twentieth century that women’s umbrellas began to be made , in a whole variety of colors.
