French psychologist Alfred Binet (1859-1911) took a different approach from most other psychologists of his day: He was interested in the workings of the 26 mind rather than the nature of mental illness.
答案：(B) normal
句中 rather than the nature of mental illness（而非精神疾病的本質）形成對比，可知 Binet 感興趣的是「正常」心智的運作，故填 normal；contrary（相反的）、detective（偵探的）、mutual（相互的）都無法與 mental illness 構成這組對照。
四個選項的字義都不難，normal 更是很早就學會的字。這一題考的不是字義，而是能不能看出句中的對照關係。
判斷的依據在 rather than 這組對照。全句 He was interested in the workings of the ___ mind rather than the nature of mental illness.（他感興趣的是…心智的運作，而不是精神疾病的本質），rather than 前後必須是一組相對的概念；後面是 mental illness（精神疾病），前面要填的自然是與之相對的「正常的」，故選 normal。同句前半 took a different approach from most other psychologists of his day（採取與當時多數心理學家不同的研究取向）也呼應這一點：別人研究的是病態，他研究的是常態。凡是句中出現 rather than 或 instead of 的題目，判斷步驟相同：先找出與空格相對的那個概念，再挑出與它相反的選項。
contrary 是「相反的」，須用於 contrary to 或 on the contrary，the contrary mind 不成說法。detective 是「偵探的」，與心理學研究的對象無關。mutual 是「相互的」，須有互相作用的雙方，本句只談一個心智。三者都無法與 mental illness 構成一組對照。
A rather than B（是 A 而不是 B）、instead of（而不是）、the workings of（…的運作方式）、normal／abnormal（正常的／異常的）、on the contrary（正好相反）。其中 instead of 這一組考過 6 個年度，83 年第 30 題 →、98 年第 27 題 →、105 年第 20 題 →、108 年第 28 題 →、110 年試辦考試第 13 題 →都出現過；on the contrary 考過 4 個年度，93 年第 29 題 →、95 年第 30 題 →、107 年第 29 題 →都出現過。
French psychologist Alfred Binet (1859-1911) took a different approach from most other psychologists of his day: He was interested in the workings of the 26 mind rather than the nature of mental illness. He wanted to find a way to measure the ability to think and reason, apart from education in any particular field.
In 1905 he developed a test in which he 27 children do tasks such as follow commands, copy patterns, name objects, and put things in order or arrange them properly. He later created a standard of measuring children's intelligence 28 the data he had collected from the French children he studied. If 70 percent of 8-year-olds could pass a particular test, then 29 on the test represented an 8-year-old's level of intelligence.
From Binet's work, the phrase "intelligence quotient" ("IQ") entered the English vocabulary. The IQ is the ratio of "mental age" to chronological age times 100, with 100 30 the average. So, an 8-year-old who passes the 10-year-old's test would have an IQ of 10/8 times 100, or 125.
