高三英语暑假作业3(3)

between male dancers and male non-dancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers --- a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic (慢性) injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one’s sensitivity to pain.

There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo injection (安慰剂) and promised that it would relieve their pain had the least discomfort --- not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work.

Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bells on a string. Today every medical textbook teaches the gate control theory as fact. There’s a problem with it, though. It explains people who have injuries but feel no pain, but it doesn’t explain the reverse, which is far more common --- the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? The rope and clapper are gone, but the bell is still ringing.

“Luck is a matter of preparation meeting opportunity,” said the American talk show host Oprah Winfrey. I’ve never watched her show, but when a self-made billionaire gives life advice it’s probably worth listening to.

Her point is that blind luck is very rare. You may have to be lucky to find a good job these days but that does not mean you should sit at home waiting for the opportunity to come to you. If you’re a Chinese, you may already be familiar with the tale of a farmer waiting by a tree stump for a rabbit to run out and break its neck.

A book by the UK psychologist Richard Wiseman, called The Luck Factor, argues we can all make ourselves luckier. It’s not about going to a temple to burn some incense (香) in hopes that the gods will give you good fortune; it’s practical advice you can follow each day.

Wiseman conducted an experiment as part of his studies. First he divided volunteers into two groups: those who said they were lucky in life and those who said they were not. He gave everyone a newspaper and asked them to look through it to count how many photographs it had inside. On average, the unlucky people took about two minutes to count the photographs while the lucky people took just seconds. Why? On the second page of the newspaper, a command, “Stop
