Question

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。有两项为多余选项。

1.From 18－25, according to I．Q. scores；but you are wiser and more experienced with increasing age. You are smartest in your 20's; around 30, your memory begins to go down, particularly your ability to perform mathematical computations. 2.__ Your vocabulary at the age of 45, for example, is three times as great as when you graduated from college. At 60, your brain has almost four times as much information as it did at the age of 21. 3.You have the best physical sense of yourself from 15 to 24; the best professional sense from 40 to 49. Before the age of 24, we believe that our happiest years are yet to come；over 30，we believe that they are behind us. A National Health survey agrees: after the age of 30, we become more realistic and do not view happiness as a goal in itself. If we keep our health, achieve professional and emotional goals, happiness, we feel, will follow.

__4.__ Generally between 30 and 39，but the peak (顶峰) varies with different professions(职业). Mosart wrote a symphony (交响曲) and four sonatas by the age of 8, and Mendelssohn composed his best­known work A Midsummer Night's Dream at 17, but most of the great music was written by men between 33 and 39.

Though the peak in most fields comes early, most Nobel Prize winners did their top research in their late 20's and 30's—creative people continue to produce work with high quality(质量) throughout their lives _5.__

A. When are you most creative (创造性的)?

B. When are you happiest?

C. When are you smartest?

D. Do you know what I．Q. refers to?

E. But your I．Q. for other tasks goes up.

F. Creative people usually produce a lot of works.

G. For the “well­conditioned mind”， there is no upper limit..（限制）

【解析】

试题分析：人生的起伏似乎没有可预知的模式，但是科学家现在发现有一些模式相当明确，绝大多数人都有不例外。即使你度过了一些最佳时期，你仍然会在将来经历另外几个最佳时期。某些最佳期时期似乎在生命的后半段才会到来。对于“状态良好的大脑”，不存在极限。

1.1】C根据下一句“根据智商得分，你从15岁至25岁最聪明”。从这里可知上一句在问：什么时候你最聪明？，故选C

2.2】E根据前面提到：20多岁的时候你的思维最敏捷；30岁左右，记忆力开始衰退，尤其是你的数学计算能力。和后面说的：例如45岁时你的词汇量是你刚从大学毕业时的3倍。60岁时你大脑中储存的信息几乎是你21岁时的4倍。所以此空表达的意思应是转折，“然而，你做其他事情的智商提高了”。因此可知选E。

3.3】B根据下一句说的“15岁至24岁之间你的身体感觉最好；40岁至49岁之间你对自己的职业感觉最佳”。可知前面应该在问：什么时候你的感觉最好？故得知选B。

4.4】A根据下面所说的：一般在30岁至39岁之间。但是不同的职业，高峰期也不相同。和后面句的一些实例，可知前面在问：什么时候你最富创造力？故选A。

5.5】G根据前面提到：虽然大多数领域的最佳状态来得比较早-----大多数诺贝尔奖获得者都是25岁以后、30多岁时完成他们最出色的研究的——但是创造型的人会在生命中不断地完成高质量的工作。可知此处表达的应该是：对于“状态良好的大脑”，不存在极限。故选G。
