单项选择题
What is intelligence We all know we have some, and some people seem to have more than others. There are various types of intelligence.
The most obvious categories that people fit into are those who are good with numbers and those who are good with words. Some of us are neither while others are both. A third category of intelligence is related to interpreting visual (视沉的)information. A common way of measuring intelligence is through the use of “IQ" or intelligence tests. These tests include many types of questions to measure different types of intelligence, but the three most important are numerical, verbal (文字的) and visual.
Most simple intelligence tests combine all three types of questions in equal numbers, so that everyone has the same chances, whether he or she is better at one type or another. The IQ is an average and says nothing about special abilities.
What factors affect the results of the IQ tests7 The number of the correct answers is only one of the important factors. If people are given enough time, most of them can answer the questions correctly. Therefore, a time limit for the test must be set. Some people will solve many of the problems in the given time, bet others will solve many of the problems in the given time, but others will solve very few. What the IQ test measures is the mental speed.
There are tow other things that may affect results: carelessness and lack of persistence. In other words, some people accept the first answer they think of without checking. Others give up too easily or refuse to spend long enough on a single question.
Although IQ tests are widely used, many people do not agree about what intelligence really is, or that IQ tests are a fair way to measure it.
