Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology will take the place of all other ways of finding out who people are.
However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct for the time being. In Britain, it was found that 91% of people who had tried it said that they like the idea of eye-recognition.
In the future your computer will be looking you in the eye. So smile!
61.The program has been tested in shops and banks of the following countries EXCEPT __________.
A. Turkey B. America C. France D. Britain
62. When you are using the eye-recognition program, you _____________.
A. look at the machine and type a number B. look at the machine
C. let the machine look at your face D. need to speak and then look
63. What does the underlined phrase “for the time being” in Para. 4 mean?
A. sometimes B. always C. never D. at present
64. How many systems are being worked on according to the text?
A. 4 B. 2 C. 6 D. 8
65. The problem with the program is that ___________.
A. it is not always correct B. eyes don’t change
C. Twins’ eyes are the same D. eyes can get dirty like hands

People appear to be born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy—one plate, one knife, one spoon, one fork, for each of the five chairs. Soon they are capable of noting that they have placed five knives, spoons and forks on the table and, a bit later, which this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and received seven years later, he or she could enter a second grade mathematics class without any serious problems of intellectual adjustment.
Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped or, as the case might be bumped into concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one.
Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers--the idea of aloneness, a prerequisite for doing anything more mathematically demanding than setting a table—is itself far from innate.
1. What's the main idea about this passage?
A. The use of mathematics in child psychology.
B. Trends in teaching mathematics to children.
C. The development of mathematical ability in children.
D. The fundamental concepts of mathematics that children must learn.
2. It can be inferred from the passage that children normally learn simple counting——.
A. soon after they learn to talk
B. after they reach second grade in school
C. by looking at the clock
D. when they begin to be mathematically mature
3. According to the passage, when small children were asked to count a pile of red and blue pencils they——.
A. counted the number of pencils of each color
B. counted only the pencils of their favorite color
C. guessed at the total number of pencils
D. subtracted the number of red pencils from the number of blue pencils
4. What does the word “They” (Para. 3, Line 5) refer?
A. Children B. Pencils C. Mathematicians D. Studies

Once the young man came into the lab while Edison 31 an important experiment. He stood near the table 32 he didn’t help him. Edison stopped 33 out a bottle and said, “Go to calculate (计算)its volume(容积)and tell me the 34 in two hours.”
At first the young man thought it easy to do it. Soon he 35 it difficult. Two hours later Edison went into his office and saw a lot of paper and books on his desk. Of course he couldn’t compute the volume in the time 36 .
“Why not pour some 37 into the bottle?” said Edison. “Then you’ll 38 calculate its volume!” Having heard this, the young man’s 39 turned red, and he knew Edison was really 40 than him!
