The defining term of intelligence in humans still seems to be the IQ score, even though IQ tests are not given as often as they used to be.

　　①The defining term of intelligence in humans still seems to be the IQ score, even though IQ tests are not given as often as they used to be.

　　②The test comes primarily in two forms: the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scales (both come in adult and children’s version).

　　③Generally costing several hundred dollars, they are usually given only by psychologists, although variations of them populate bookstores and the World Wide Web.

　　④Superhigh scores like vos Savant’s are no longer possible, because scoring is now based on a statistical population distribution among age peers, rather than simply dividing the mental age by the chronological age and multiplying by 100.

　　⑤Other standardized tests, such as the Scholastic Assessment Test (SAT) and the Graduate Record Exam (GRE), capture the main aspects of IQ tests.

　　②(具体：分1)智商测试主要有两种形式：斯坦福—比奈智力量表和韦氏智力量表(二者都有成人和儿童版本)。

　　③(并列：分2)虽然这两种测试形式的改编版本常常可以在书店和互联网上见到，但它们通常只由心理学家提供，费用一般为几百美元。

　　④(并列：分3)莎凡那样的超高分数不可能再重现，因为现在分数的计算是以同龄群体分数分布为基础的，而不是简单地用智力年龄除以实足年龄再乘以 100。

　　⑤(并列：分4)其它的标准化测试，比如学术评估测验和研究生入学考试，都具有智商测试的主要特点。
