Intelligence Quotient
I.Q. stands for “Intelligence Quotient” which is a measure of a person's intelligence found by means of an intelligence test. Before marks gained in such a test can be useful as information about a person, they must be compared with some standard, or norm(规范). It is not enough simply to know that a boy of thirteen has scored, say, ninety marks in a particular test. To know whether he is clever, average or dull, his marks must be compared with the average achieved by other boys of thirteen in that test.
In 1906 the psychologist, Alfred Binet (1857--1911), devised the standard by 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 for measuring intelligence, and he hit upon the very simple concept of “mental age”.
First of all, 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.For instance, he found that the average child of seven could count backwards from 20 to 1 and the average child of three could repeat the sentence:" We are going to have a good time in the country ."Billet arranged the various tests in order of difficulty, and used them as a scale against 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 in terms of a norm merely by subtracting(减去) the “mental” age of a child from his “chronological” age. Then the boy in the example given would be 'three years retarded'(迟缓、耽误). Later 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 a mental age of nine has a mental ratio of 0.75.
The “mental age” measurement was then replaced by the more famous I.Q.(intelligence quotient)

D.the same child at different ages
2.The word “defective” refers to ________.
A.average children B.poor children
C.children of low intelligence D.very intelligent children
3.Binet used a large number of children in his tests because he wanted to find out________.
A.who were the most stupid B.the defectives
C.what a bright child could do D.a norm
4.The purpose of I.Q. test is to find out ______________.
A.whether one has the intelligence of thirteen-year-old children
B.whether one is clever, average or dull
C.whether one is mature enough for his age
D.whether one is tall enough for his age
5.The I.Q. is___________________.
A.the mental age divided by the chronological age and multiplied by a hundred
B.the mental age multiplied by the chronological age and divided by a hundred
C.the chronological age divided by mental age and multiplied by a hundred
D.the average age divided by the mental age and multiplied by a hundred.

People with bigger brains ftend to score higher on standardized tests of intelligence, according to new study findings.
However, the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “not particularly large”, McDaniel noted. “There’s some relationship between brain size and intelligence on the average, but there’s plenty of room for exceptions,” he said.
Interest in the relationship between brain size and intelligence grew in the1830s, when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was “an unquestionable connection between the size of the brain and the mental energy displayed by the individual man”. Since that statement, scientists have conducted numerous studies to determine if Tiedmann’s assertion was, in fact, correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan(核磁共振成像扫描).
For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence.
McDaniel is not sure why the relationship was stronger for adults and women. “Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well—if not higher—in tests of intelligence,” he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-sized people who are highly intelligent,” he said, “But, on the average, the relationship holds.”

We like to consider ourselves the superior race, and we are. It’s true that we are getting to know more and more, and we actually live in “the information age”. Our human vanity(虚荣心) makes us believe that we really have to know everything! Surprisingly, we do not have this ability. The question “what is happening in the Bermuda Triangle” is the very proof.
Where is the Bermuda Triangle located? The mysterious triangle is believed to be situated between Florida, Bermuda and Puerto Rico, where too many unusual events have happened.
On December the 5th 1945, five U.S. military planes took off from Florida on a clear day only to disappear over Bermuda. Furthermore, some other disappearances took place; in 1947, an American C54 plane simply disappeared at 100 miles from Bermuda; at 80 miles, a Star Tiger plane disappeared in 1948.
Even Columbus had trouble in Bermuda. Some of his journals were about the strange happenings there: “the waters are changing their colors” and “compasses are going wild”.
Maybe it’s why it is called the Devil’s triangle or the Atlantic cemetery.
Many hypotheses were stated in order to explain the strange events. In spite of these attempts, the mystery of the Bermuda Triangle remains unsolved.
Some people get to say that maybe aliens are involved in it. Other imaginative scientists relate the happenings in Bermuda to Einstein’s theory, saying that the missing ships and planes are translated to another dimension of space and time and taken into another world.
Maybe we will just have to wait to go to Heaven and ask the One who made it. The answer will surely be a satisfying one!
