In February 2010, Lydia Angyiou and her two sons were walking through their village in northern Canada. The sound of children shouting made her turn around. To her horror, Lydia saw a 700 – pound polar bear behind her eyeing her seven-year-old son．Getting between the bear and her child, Lydia yelled at the children to run away．She then began hitting and kicking the animal as hard as she could．A neighbor who heard all the noise came and shot the bear．But everyone agreed it was Lydia who had saved her children's lives．A local policeman described it this way: "I guess when your back is up against the wall, we come up with super-human strength."

Where does this "super-human strength" , courage and quick thinking come from? Experts say it comes from stress! In stressful situations, the body releases chemicals that prepare it to take action．These chemicals give people the speed and strength they need to fight danger or run away from it．

When we think of stress, we usually think of its negative effects．Studies, though, show that moderate levels of stress are actually helpful．In fact, the way we perform is usually affected by the amount of stress we feel．Stress causes the brain to release adrenaline （腎上腺素）which in turn increases our energy and excitement．The chemical gives us clearer minds and helps us to do more．This is why some people say they work better under a deadline．Adrenaline that is not released for long periods of time can cause us to be bored and lazy. So some stress actually increases and strengthens our abilities instead of weakening them. We sometimes turn out our very best work when we push ourselves to the limit．Stress can also make us more confident．Handling small amounts of stress now prepares us for handling serious situations in the future．Who knows? Today's stress may even prepare us for the next polar bear that comes along!

60．The author mentions the story of the mother and her children mainly to ___________.

       B．show us how much the mother loves her children

61．What does the word “it” underlined in the second paragraph refer to?

       A．released chemical           B．the body          C．stress                D．strength

62．What will the author probably continue to write in the paragraph that follows?

       A．How to deal with a bear when you meet with it unfortunately.

       B．Why we need small stress in life.

       C．Tips for a person to develop his ability of dealing with stress.

       D．When the brain releases adrenaline.

       Our brains work in complex and strange ways．There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two．Others can perform complex classical piano pieces after hearing them once, but they cannot read or write．

       Dr．J．Langdon Down first described this condition in 1887．He called these people idiot savants．An idiot savant is a person who has significant mental impairment （損傷） , such as in autism ( 孤獨(dú)癥，自閉癥) or retardation．At the same time, the person also exhibits some extraordinary skills, which are unusual for most people．The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory．

       One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr．Benjamin Rush, an American doctor．His patient, Thomas Fuller, was brought to Virginia as a slave in1724．It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds．Despite this ability, he died in 1790 without ever learning to read or write．

       Another idiot savant slave became famous as a pianist in the 1860s．Blind Tom had a vocabulary of only 100 words, but he played 5 ,000 musical pieces beautifully．

       In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly．

       Today we more clearly recognize that the idiot savant is special because of brain impairment．Yet not all brain impairment leads to savant skills．Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills．However few people wish to participate in such experiments．There are many excellent reasons for not undergoing unnecessary experimentation on one's brain．The term idiot savant is outdated and inappropriate．Virtually all savants have a high degree of intelligence and are thus not idiots．

What does the passage mainly talk about?

       A．Idiot savants have areas of outstanding abilities．

       B．Human Beings have complicated thinking process．

       C．The brains of the idiot savants are partly impaired．

       D．The reasons why people have wonderful skills vary．

Which of the following can be done by Rain Man?

       A．He can play wonderful pieces of classical music．

       B．He can guess out exactly the length of a man's life．

       C．He can memorize the contents of the pictures fast．

       D．He can count matches dropped on the floor quickly．

What can you infer from the passage?

       A．Idiot savants have real talents for art and math．

       B．Dr．Down is the first person who found idiot savants．

       C．Few people wish to risk becoming savants by brain operations．

       D．Intentional left brain impairments will surely lead to idiot savants．
