Before the early 1960’s people interested in the differing roles of the left and right hemispheres(半球) of the brain depended almost entirely on facts drawn from animal research, form studies of patients with one-sided brain damage. But it was possible to find out which brain hemisphere was most involved in speech and other functions in normal people by having them listen to two different words coming to the two ears at the same time. This became known as the “dichotic listening” procedure. When several word pairs are given in a row, people are unable to report them all, and most right-handers prefer to report, and report more correctly, words given to their right ears. This seems to be related to the fact that signals from the right ear, although sent to both hemispheres, are better sent to the left hemisphere which controls speech. People who have speech represented(回忆) in the right hemisphere, a very unusual occurrence even in left-handed people, more correctly report what their left ears hear.
In contrast to the right-ear advantage for speech, there is generally a left-ear advantage for another type of auditory(听觉的) signal: music. When right-handed people listen to melodic patterns they report them better from the left ear.

Zipped into a bag, it looks like a large umbrella. Unfolded, it goes along the street like any other bicycle.
It's the "A-bike", the brainchild (脑力劳动的产物) of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the world's first pocket calculator. He described his new invention as "the world's smallest, lightest foldable bicycle".
"My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used,"said Sinclair.
The mini-bike, showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly US$300, is built for riders as heavy as 112 kilograms and is height-adjustable（可调整高度的）. It takes about 20 seconds to fold or unfold.
Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers per hour)," he said. Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters （立方米）.
Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years.

Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23.It was the third shark attack along the coast of Australia's largest city in a month.
The 15-year-old boy and his father were in the water off Avalon，on Sydney's northern beaches，around dawn when he was attacked.The city's beaches are packed with locals and tourists during the summer months.
“The father heard a scream and turned to see his son thrashing(激烈扭动)about in the water，”the police said.“Fortunately，the shark swam away and the boy was helped to the shore by his father.”
Lifesaving Club spokesman Nick Miller said，“It got him around the top of his left leg and the father came and dragged him out of water.”He said the boy was bleeding heavily when he was brought to the shore.“There was a lot of pain，as you can imagine.”The teenager was airlifted to hospital for treatment for leg injuries.
Police said the bites “cut through to the bone”，but the boy did not appear to have sustained any fractures (骨折)．He was in a stable condition now.
Several beaches were closed after the attack.Water police and lifeguards were searching for the shark，while the police hoped to identify its species by the shape of the bite marks.But they said it was too early to say what type of shark attacked the boy.“I don't even know if he saw it，”Miller said.
Many shark species live in the waters off Sydney's beaches，but attacks on humans are still relatively rare.However，there were two attacks on successive days earlier this month，one on a navy diver in Sydney harbor，not far from the famous Opera House，and the other on a surfer at the city's world-famous Bondi beach.
Fishermen say shark numbers are on the rise.There is a ban on commercial fishing in the harbor，which has increased fish stocks.Marine experts also claim environmental protection has created a cleaner environment，attracting sharks closer to the shore as they chase fish.Many shark species，including the Great White—the man-eaters made famous in Steven Spielberg's Jaws—are protected in Australian waters.

I did very badly at school. My headmaster thought I was 1 and when I was 14 he said, “You’re never going to be 2 but a failure.”
After five years of 3 jobs, I fell in love with a very nice middle-class girl. It was the best 4 that could have happened to me. I 5 I wanted to do something positive (积极地) with my life because I wanted to prove to 6 that what people said about me was 7 . Especially her mother, who had said to me, “Let’s 8 it, you’ve failed at everything you’ve ever done.” So I tried hard with my 9 and went to college. My first novel (小说) 10 while I was at college.
`After college I taught during the 11 in high schools and attended evening classes at London University, where I got a 12 in history.

I began to feel proud of myself — 15 was a working-class boy who’d 16 school early, now teaching at the university
My writing career (职业) took off when I discovered my own style. Now I’m rich and 17 , have been on TV, and met lots of film stars. 18 what does it mean? I 19 wish all the people that have put me down had 20 : “I believe in you. You’ll succeed.”
