How can a single stamp be worth $ 16 800？
Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony (殖民地) of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer—Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius ' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally marked the words " Post Office" instead of " Post Paid" on the several hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left—fourteen One-Penny Orange-Reds and twelve Two-Penny Blues. Because of the Two-Penny Blue's rareness and age, collectors have paid as much as $ 16800 for it.
Mauritius is the name of______.
A．an island kingdom
B．a British colony
C．a province of India
D．a London printer
The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver's side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over.
After a student has passed the driver's education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), he must take his driver's test. The person must pass all three tests in order to be given a driver's license. If the person does well in his or her driver's education class, he or she will pass the test with flying colors and get a driver's license.

In 1906 the psychologist, Alfred Binet, devised the standard in relation to which intelligence has since been assessed. Binet was asked to find a method of selecting all children in the schools of Paris who should be taken out of ordinary classes and put in special classes for defectives. The problem brought home to him the need for a standard of intelligence, and he hit upon the very simple concept of" mental age".
First, he invented a variety of tests and put large numbers of children of different ages through them. He then found at what age each test was passed by the average child. Binet arranged the various tests in order of difficulty, and used them as a scale by which he could measure every individual. If, for example, a boy aged twelve could only do tests that were passed by the average boy of nine, Binet held that he was three years below average, and that he had a mental age of nine.
The concept of mental age provided Binet, and through him, other psychologists with the required standard. It enabled him to state scores in intelligence tests m terms of norm. At first, it was usual to express the result of a test by the difference between the" mental" and the" chronological" age. Then the boy in the example given would be" three years retarded". Soon, however, the" mental ratio" was introduced; that is to say, the ratio of the mental age to the chronological age. Thus a boy of twelve with mental age of nine has a mental ratio of 0.75.
The mental age was replaced by the intelligence quotient or" I. Q". Clearly, since the mental age of the average child is equal to the chronological age, the average I. Q. is 100.
To judge a child's standard, his marks in a test must be compared with marks gained by ______.
A．others of the same age
B．older children
C．younger children
D．adults
