　　Science is based upon observation. However, observation 1 is not science. Scientists 2 state a problem, which then guides them in their observations. But without observation people generally are not 3 of a problem. This then raises a question 4 comes first, the observation or the problems?

　　Curiosity awakens a need 5 observation. Observation will usually 6 specific questions in the mind of a scientist. To 7 his curiosity he begins to make observations. 8 , he formulates a specific statement that can be tested. This statement is called a hypothesis (假设). It is the starting point for an experiment.

　　 9 experimenting, the scientist tries to show or prove that the hypothesis is true or false. He 10 use good 11 to create an experiment that 12 the problem. The experiment must produce valid information or data. The date 13 during the experiment are observations.

　　Observations can be made directly and indirectly. For direct observation, instruments are 14 used. Some instruments used by modern scientists are quite simple; others are very 15 .

　　To complete his experiment, the scientist must state his observations in numerical 16 . This means that he has to make measurements. With the results from these he can make more 17 comparisons or descriptions to 18 his hypothesis. The results of a scientific experiment 19 on a valid hypothesis can often 20 a better understanding of the world and the universe.

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.”

1.. What does the text mainly talk about？

A.MRI scans are applied to intelligence.

B. On the average， a bigger brain means higher IQ.

C. Dr McDaniel did well in his intelligence study.

D. Scientists are interested in Tiedmann’s idea.

2. 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

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

A. experiment   B. statement   C proof       D. demand

4. 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

5. 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
