Uncertainty spreads through our lives so thoroughly that it dominates our langua

题型:不详难度:来源:

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 imprecision is not necessarily to be criticized. Indeed, it has a value Just because it allows uw to express judgments when a precise quantitative statement is out of the question.
We have been trying to pin down by experiments what people meari 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 may 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 me 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.
51. What"s the right attitude towards the words like probably, any and 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.
52. Why do we do experiments with the words many and some?
A. To prove that people are insensitive to these words.
B. To prove that 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.
53. Which of the following expressions means a larger chance in weather broadcast?
A. Possible.   B. Probable.   C. Be likely to.  D. Be certain to.
54. Which of the following is similar to the underlined word signifies in its meaning?
A. makes    B. means     C. predicts    D. indicates
55. Which of the following can be the best title for the passage?
A. Uncertainty in the Language Use.
B. How to Use Language in an Uncertain Way
C.Uncertain Words and their Use in Specific Contexts
D. Experiments on Relationship between Uncertainty and Language Use

Pretoria, South Africa – Hundreds of swimmers play in the water along a South Africa beach. Suddenly a huge shark appears off shore and heads for the bathers. Before it can get close to the swimmers, the shark, for some mysterious reason, starts swimming parallel to the beach. Then it turns away from the shore and heads out to sea, leaving the swimmers untouched.
Such a scene will soon become common along shark-in-fasted (鲨鱼成群的) shores. An electrical engineer from the University of Pretoria has developed an electrical system that repels (击退) sharks by controlling their movements. Confused by this action, the sharks end up turning away from the beach.
In this unusual shark-repellent method, an insulated (绝缘的) cable is buried on the bottom of the sea around a beach where people swim. When an electric current is sent through the cable, an electric field is produced in the water above the cable.
When shark swims into the electric field, nerve cells just below the shark" s skin will sense the field. The electricity produces a reflex (反射作用) action in the shark" s muscles, causing the dangerous animal to swim parallel to the cable. Confused by increasing loss of control of its muscles, the shark suddenly changes its direction and heads seaward, away from the electric field.
In a test of the invisible new shark-repellent system, a cable was placed around a beach in St. Lucia, an island around the beach a long time ago to keep sharks away from swimmers, and a net was left in place during the experiment.
When the electric field was left on for more than a year and a half, no sharks were found in the net. However, when the power was turned off,89 sharks ended up in the net.
Using the electric-wall method instead of net to protect bathers would avoid the needless death of many sharks, said biologists. Currently, thousands of sharks die each year when they become trapped in protective nets that surround holiday resorts in Africa and Australia.  About 10 to 15 humans are killed by sharks annually.
1.Why doesn" t the shark attack the swimmers according to the passage?
A.Because there are so many swimmers in the water.
B.Because the shark isn’t so hungry as to eat the swimmers.
C.Because of some mysterious power from the heaven.
D.Because there is an invisible electric field confusing the shark.
2.An electrical engineer from the University of Pretoria has developed __      .
A.a protective net   
B.a new shark-repellent system
C.the electric field        
D.an insulated cable
3.An electric field is produced in the water above the cable         .
A.only when a shark swims into the electric field
B.only when an insulated cable is buried on the bottom of the sea around a beach where people swim
C.only when an electric current is sent through the cable
D.only when the sharks are trapped in protective nets
4.Which of the following is NOT TRUE according to the passage?
A.Protective nets had been fixed earlier than the new shark-repellent system.
B.The new shark – repellent system will probably replace the protective nets.
C.Thousands of sharks have died each year since this new system was put into use.
D.Using the electric-wall instead of nets would avoid the needless death of many sharks.
