Windsurfing is a sport that combines sailing and surfing.In 1948,twenty-year-old Newman Darby first thought of using a handheld sail to contro1 a small boat.Darby did not apply for a patent(专利)for his design at first.However,he is recognized as the inventor of the first sailboard.
Californians Jim Drake,a sailor and engineer,and Hoyle Schweitzer,a surfer and skier received the patent for a sailboard.They called their design a windsurfer.The early windsurfer boards measured 3.5 meters long and weighed 60 pounds.Later in the l980s,Newman Darby did apply for and receive a design patent for a one—person sailboat.
In the late l940s,Newman Darby found he could control a 3-meter-long sailboat and make turns even without a rudder(舵).In l964 he designed the first universal joint(万向接头)to go along with a flat bottom sailing boat.This sailboard was equipped with a universal joint,a board and a kite—shaped free sail and thus windsurfing was born.
Naomi Darby,Newman’s wife,was the first woman windsurfer and helped her husband build and design the first sailboard.She sailed while standing up,controlling the boat without the use of a rudder.She tilted(倾斜)the sail to change directions.This was something that had never been done before.
Hoyle Schweitzer began producing sailboards in the early 1970s.The sport became very popular in Europe.By the late 1970s,windsurfing fever had Europe firmly in its grasp with one in every three families having a sailboard.
The first windsurfing world championship was held in 1973.Windsurfing first became an Olympic sport for men in l984 and for women in l992.

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.

C
A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (确保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.
“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的) sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it’s not just a matter of choice –their bodies are going through a change of sleep patters.
All of this makes the transfer from middle school to high school—which may start one hour earlier in the morning ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescent are up against difficulties when it conics to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
Carskadon suggests that high schools should not start classes so early in the morning because ________.
A. it is really tough for parents to enforce bedtime
B. it is biologically difficult for students to rise early
C. students work so late at night that they can’t get up early
D. students are so lazy that they don’t like to go to school early
The underlined phrase “nod off” most probably means “ _______”.
A. turn around B. agree with others C. fall asleep D. refuse to work
What might be a reason for the hard transfer from middle school to high school?
A. Adolescents depend more on their parents.
B. Adolescents have to choose their sleep patterns.
C. Adolescents sleep better than they did at childhood.
D. Adolescents need more sleep than they used to.
What is the test mainly about?
A. Adolescent heath care. B. Problems in adolescent learning.
C. Adolescent sleep difficulties. D. Changes in adolescent sleep needs and patterns.
