  Uncertainty spreads through our lives so thoroughly that it dominates our language. Our everyday speech is made up in large part of words like probably, many, soon, great, little. What do these words mean?

   Such verbal expression is not necessarily to be criticized. Indeed, it has a value just because it allows us to express judgments when a precise quantitative statement is out of the question.

We have been trying to pin down by experiments what people mean by these expressions in specific contexts, and how the meanings change with age. For instance, a subject is told “There are many trees in the park” and is asked to say what number the word many mean to him. Or a child is invited to take “some” sweets from a bowl and we then count how many he has taken. We compare the number he takes when he is alone with the number when one or more other children are present and are to take some sweets after him, or with the number he takes when told to give “some” sweets to another child.

  First, we find that the number depends, of course, on the items involved. To most people some friends means about five, while some trees means about twenty. However, unrelated areas sometimes show parallel values. For instance, the language of probability seems to mean about the same thing in predictions about the weather and about politics: the expression “is certain to” (rain, or be elected) signifies to the average person about a 70 percent chance; “is likely to”, about a 60 percent chance; “probably will” about 55 percent.

  Secondly, the size of the population of items influences the value assigned to an expression. Thus, if we tell a subject to take “a few” or “ a lot of” glass balls from a box, he will take more if the box contains a large number of glass balls than if it has a small number. But not proportionately more: if we increase the number of glass balls eight times, the subject takes only half as large a percentage of the total.

   Thirdly, there is a marked change with age. Among children between six and fourteen years old, the older the child, the fewer glass balls he will take. But the difference between a lot and a few widens with age. This age effect is so consistent that it might be used as a test of intelligence.

46. What’s the right attitude towards the words like probably, many, soon?

 A. They are inaccurate and we should avoid them.

 B. They are necessary since we cannot be always precise.

 C. They should be criticized because there are too many of them

 D. Their value is not yet clear since we don’t know their meaning

47. Why do we do experiments with the words “many” and “some”?

 A. To prove people are insensitive to these words.

 B. To prove the words dominate our everyday speech

 C. To find out how the meanings vary with age and contexts

 D. To find out whether the words can mean a precise quantity

48. Which of the expressions means a larger chance in weather broadcast?

 A. Possible     B. Probable    C. Be likely to   D. Be certain to

49. Which of the following will least definitely influence the number of items a kid takes out of a box when he is invited to take “some”?

 A. whether the quantity of items is large or small

 B. whether the items are candies or toys

 C. whether the kid is a toddler or a youngster

 D. whether the kid is alone or accompanied by other children

50. What will tell us about the intelligence of a child?

 A. The consistency of picking up a certain glass ball

 B. How many glass balls he will take when he’s asked to

 C. The difference between a lot and a few when he takes glass balls

 D. Whether there are marked changes in his first pick and second one

A Magical Experience

  One hot August afternoon, Deena Hoagland and her son Joe sat on a floating platform at Dolphins Plus, a marine(海洋)center near their home in Florida. Nearby, a large, powerful, six-hundred-pound dolphin circled to study the mother and her child. Suddenly, it splashed the Hoaglands with water. That is when something amazing happened. Three-year-old Joe Hoagland smiled. Sitting with Joe on her lap, Deena smiled, too, as her heart leapt with joy. It was the first sign of hope she had seen in Joe since his stroke(中风)six weeks earlier.

  Joe Hoagland was born with a rare heart condition that had forced him to spend much of his first three years of life in hospitals. After a series of open-heart surgeries, Joe seemed to be doing better, but the last surgery on his heart resulted in a stroke, which left him unable to move one side and to see out of one eye.

  Worse still, the spirit of the child, who had bravely battled his illness until then was seemingly broken. Afraid of his doctors and unwilling to participate in efforts at physical therapy(治疗), Joe grew listless, losing interest even in his favorite toys.

  Having heard of a new therapeutic approach termed “dolphin-assisted therapy,” Deena phoned Dolphins Plus and asked permission to bring her son along. There Joe met Fonzie, the playful dolphin. With each passing visit, Joe seemed to make more progress. Before long, he was regaining some movement on his left side. Dolphins Plus trainers urged Joe to get into the water and swim with his new friend. Joe, however, was reluctant. Gradually, though, Joe became more comfortable with the large dolphin, and by mid-September, Joe was swimming with his friends.

  Over the next two years, Joe fully recovered from the paralysis and partial blindness that his doctors thought irreversible. Now a healthy, active teenager, Joe lives a life similar to any of his friends. He visits and swims frequently with his friend Fonzie and helps his parent with Island Dolphin Care. Deena started Island Dolphin Care to work with Dolphins Plus to share the benefits of dolphin therapy with other special-needs children and their parents.
