Each Indian(印第安人) was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates(游戏伙伴) would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.

   The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-Of-a-Horse. So an Indian’s name told his record or described the kind of man he was.

A man was given many chances to improve his name, however. If in a later battle he was brave in fighting against the enemy, he was given a batter name. Some of our great fighters had as many as twelve names—all good and each better than the last.

An Indian’s names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.

Sometimes an Indian would be asked to give his name to a son who had performed a noticed deed. I know of only three of four times when this happened. It is the rarest honor for a person—the honor of assuming(承担) his father’ name.

The greatest honor an Indian could earn was__________.

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.”

By mentioning Albert Einstein, the writer wants to show    .

A. Albert Einstein was intelligent

B. the result of intelligence test was false

C. being hard working is more important than intelligence

D. brain size doesn’t necessarily decide the level of intelligence

The underlined word “assertion” in Para. 3 probably means “    ”.

A. experiment   B. statement   C proof       D. demand

After Frederich Tiedmann wrote his article,     .

A. many scientists agreed with him

B. numerous studies have failed to prove his idea

C.MRI scan became popularly used

D. lots of researchers were interested in the connections between head size and intelligence

According to the text, Dr McDaniel’s study    .

A. proves Tiedmann’s idea was completely true

B. shows women are smarter than men

C. involves many studies and a lot of people

D. explains why people with smaller brains are clever
