Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It’s a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century.
But nearly all scientists now agree the 10 percent theory is completely unfounded. In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes.
Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o’ the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don’t affect other essential areas.
From an evolutionary point of view, it’s highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 10 percent theory.
How did the 10 percent theory get such widespread popularity?

A．It was promoted in various types of copular media.

B．Most brain disorders affect the same part of the brain.

C．The brain is less active during times of sleep.

D．The 10 percent theory does not make evolutionary sense.

What can we infer from the passage?

The dirty, homeless man sat on the pavement, staring at the atones. He thought back more than twenty years to when he was a boy living in a small red brick house on this very street. He recalled the flower garden, the swing his dad made, and the bike he had saved up for months to buy.
The man shrugged impatiently, for the brightness of those pictures hurt him, and his memory travelled on another ten years. He had a job by then, plenty of friends and started to come home less. He did not really want to remember those years, nor the day when, because o’ debts, he had gone home planning to ask for money. He felt embarrassed, but he knew exactly where his dad kept the money. When his parents stepped out of the room, he took what he wanted and left.
That was the last time he had seen them. Ashamed, he went abroad, and his parents knew nothing about the years of wandering or time in prison. But locked in his cell he often thought of home. Once free, he would love to see his parents again, if they were still alive, and still wanted to see him.
When his prison time was up, he found -a job, but couldn’t settle. Something was drawing him home. He did not want to arrive penniless, so he hitchhiked most of the long journey back. But less than a mile from his destination he started to feel sick with doubt. Could they ever accept this man who had so bitterly disappointed them?
He spent most of that day sitting under a tree. That evening he posted a letter which, although short, had taken him hours to write. It ended with:
I know it is unreasonable of me to suppose you want to see me ... so it’s up to you. I’ll come early Thursday morning. If you want me home, hang a white handkerchief in the window of my old bedroom. If it’s there, I’ll come in; if not, I’ll wave good-bye and go.
And now it was Thursday morning and he was sitting on the pavement at the end of the street. Finally he got up and walked slowly toward the old house. He drew a long breath and looked.
His parents were taking no risks. ________________________________________________

When movie star Scarlett Johansson was photographed naming in Los Angeles recently, she attracted a lot of attention; for the 27-year-old actress was wearing Vibram FiveFingers, so called because they look more like gloves than shoes, with a space for each toe.
Strange though they may look, these so-called barefoot shoes, which reproduce the effect of barefoot running but with less pain, are just one brand in a range of minimalist footwear. These super-thin sports shoes are causing a stir in the world of running and fitness. Why? Because some experts believe they could make you a better, more efficient runner and that traditional trainers could be doing you more harm than good.
"Wearing a shoe that has lots of cushioning and support affects the way your body naturally moves and studies suggest that this carries a higher risk of injury," explains Matt Wallden, an athlete performance expert. "But with barefoot shoes, the foot can actually feel the firmness and shape of the ground, which allows your body to respond effectively.’"
But before you rush out to invest in minimalist footwear, be careful. These kinds of shoes are not meant for everyone, or at least not straight away.
"Ordinary sports shoes with support are good for beginners whose bodies are not used to the impact of running," explains Patrick Davoren, former Olympic athlete. "It you are not in great condition, then running in minimalist footwear may cause injuries and will turn a lot of people off exercise and running.
If you are currently injured, and figures show that in any given year 65% of all runners are, it can be tempting to try anything that promises to get you back on the road, trail, or beach. But barefoot running is not a method of treating injury nor is it a magical way of suddenly turning you into a great athlete.
Even if you’re used to running, when you start using minimalist shoes you should build up your distance gradually. Start_off’by doing just 10% of what you’d normally run and increase the distance by no more than 10% every week. And a word of warning - you may never have soft feet again
The Vibram FiveFingers are shoes ______.

A．specifically designed for women

B．that have lots of cushion inside

C．safest for people who enjoy sports

D．that are much thinner than normal sports shoes

A．experts

B．feet

C．shoes

D．runners

According to Matt Wallden, the new shoes ________.

A．make feet more sensitive to the running surface

B．will produce immediate improvements

C．force your body to move less naturally

D．increase the chances of getting hurt

The author suggests that new users of Vibram FiveFingers should ________.

A．run in the shoes every day at top speed

B．begin with a shorter running distance than normal

C．occasionally run barefooted to harden their feet

D．make sure they are already very fit before using them

Beatrix Potter was a great English writer and artist, best known for her children’s books featuring animal characters such as in the children’s classic -- The Tale of Peter Rabbit.
Beatrix was born into a rich London-based family where she was tutored by very strict private teachers and so spent her youth isolated from other youngsters.
During her youth she had a lot of pets and spent vacations in Scotland and also the Lake District. It was at the Lake District that she developed a love of wildlife. She studied the area’s natural wonders carefully and painted them continuously. But her old-fashioned, Manchester-born parents discouraged her intellectual improvement, thinking it inappropriate for a young lady. However, her study and watercolour paintings of wild mushrooms made her widely respected within the field of biology.
In her 30’s, Beatrix Potter wrote the remarkably successful kid’s book, The Tale of Pew Rabbit. Close to that time she became secretly engaged to her publisher Norman Warne. This caused a great disagreement with her parents, who did not approve of Beatrix getting married to somebody of lower social status. Sadly, Warne died before the marriage ceremony.
Ultimately Beatrix Potter began writing and also illustrating (绘图) kid’s books full-time. Using profits from her books, Beatrix grew to become economically independent of her parents and was eventually in a position to buy Hill Top Farm in the Lake District. She extended the property with additional purchases of neighbouring land over time. In her 40’s, Bestrix married William Heelis, a local lawyer. She ended up becoming a sheep breeder and farmer while continuing to publish as well as illustrate books for children. In all she authored 23 publications.
Beatrix died on December 22, 1943, and left the majority of her property to the National Trust. Her books carry on selling well globally, in many different languages. Her stories have been retold in numerous formats including a ballet, movies, and cartoons.
Such is her reputation, and that of the characters from her publications, that many Beatrix Potter statues have been created. These tiny Beatrix Potter statues which include pretty much all the actual characters in her publications have become highly valued by art collects and fans of her literature throughout the world.

Some plants get so hungry they eat flies, spiders, and even small frogs. What’s more amazing is that these plants occur naturally (in special environment) in every state. In fact, they’re found on every continent except Antarctica.
You’ve probably seen a Venus’ flytrap. It’s often sold in museum gift stores, department stores, and even supermarkets. A small plant, it grows 6 to 8 inches tall in a container. At the end of its stalks（茎）are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger(触发) hairs. When an insect lands on them, the trap suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus’ flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society’s Newsletter. Note: Despite any science –fiction stories you might have read, no meat-eating plant does any danger to humans.
Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following: “attract, kill, digest, and absorb” some forms of insects, including flies, butterflies, and moths. Meat-eating plants look and act like other green plants ---well, most of the time.
All green plants make sugar through a process called photosynthesis(光合作用). Plants use the sugar to make food. What makes “meat-eating” plants different is their bug-catching leaves. They need insects for one reason: nitrogen(氮). Nitrogen is a nutrient that they can’t obtain any other way. Why almost all green plants on our planet get nitrogen from the soil “Meat-eating” plants can’t. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity(酸度). So they’ve come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to “meat-eating” plants. Never fertilize(施肥)them! But don’t worry, either, if they never seem to catch any insects. They can survive, but they’ll grow very slowly.
