Our brains work in complex and strange ways. There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two. Others can perform complex classical piano pieces after hearing them once, but they cannot read or write.

Dr. J. Langdon Down first described this condition in 1887. He called these people idiot savants. An idiot savant is a person who has significant mental injury, such as in autism (自闭症) or retardation. At the same time, the person also exhibits some extraordinary skills, which are unusual for most people. The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory. One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr. Benjamin Rush, an American doctor. His patient, Thomas Fuller, was brought to Virginia as a slave in 1724. It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds. Despite this ability, he died in 1790 without ever learning to read or write.

Another idiot savant slave became famous as a pianist in the 1860s. Blind Tom had a vocabulary of only 100 words, but he played 5,000 musical pieces beautifully.

In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly.

Today we more clearly recognize that the idiot savant is special because of brain impairment. Yet not all brain injury leads to savant skills. Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills. However few people wish to participate in such experiments. There are many excellent reasons for not undergoing unnecessary experimentation on one’s brain. The term idiot savant is outdated and inappropriate. Virtually all savants have a high degree of intelligence and are thus not idiots.

1.The first paragraph is presented by ________.

A. stating the background of the text

B. making a definition of “idiot savant”

C. giving examples to lead in the topic

D. making comparison to show our brains work

2.According to the text, which of the following statements is true?

A. The concept “idiot savant” was first out forward by Dr. Rush.

B. Thomas Fuller who could calculate quickly is poor in art.

C. The idiot savant played by Dustin Hoffman is good at calculation.

D. Tom Cruise has the ability to perform rapid complex calculations.

3.From the last paragraph, we know that ________.

A. brain impairment is a kind of incurable disease

B. the idiot savant may result from the purposeful interruption of the brain

C. experiments on one’s brain are harmful

D. idiot savants are actually very clever in certain fields

4.The text mainly talks about ________.

A. the understanding of idiot savants

B. mental impairment in our work

C. the way that our brains work

D. how to be an idiot savant

 

1.C 2.C 3.D 4.A 【解析】本文围绕“低能特才”这一概念的提出和几个有关“低能特才”的典型例子介绍,得出“低能特才”并非真正低能这一结论,是对该概念的重新诠释。 1.细节理解题。文章第一段列举了一些“低能特才”的例子,为第二段“低能特才”这一话题的出现作铺垫,故答案选C。 2.细节理解题。“低能特才”这个概念最早是Dr. J. Langdon Down提出的,故A项错误;Thomas Fuller是从来没有学过读、写,而不是在艺术方面薄弱,故B项错误;根据第五段中的“Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise,with his ability to perform complex calculations very rapidly.”可知,Dustin Hoffman扮演的低能特才有擅长复杂计算的能力,这让Tom Cruise扮演的哥哥感到吃惊,故答案选C。 3.推理判断题。本题A项在文章中未提及;B项漏掉了左边大脑这个细节;C项描述过于绝对,且原文未提及脑实验有害,故答案选D。 4.主旨大意题。本文围绕“低能特才”这一概念的提出和几个有关“低能特才”的典型例子介绍,得出“低能特才”并非真正低能这一结论,是对该概念的重新诠释,故答案选A。

My family was gathered for a barbecue when the discussion arose about a celebrity who earned a large amount of money. The major criteria for receiving millions of dollars seem to be determined by how much the audience will pay to watch the performer achieve.

The discussion led to a sudden self-questioning. Why did I choose teaching for a career? I half-listened to their conversation as I pondered the answer.

I remembered my three children watching me spend nights planning for my class. I remembered how they intently listened to my frustrations concerning materials, procedures and the amount of responsibility that seemed to endlessly be thrust into the laps of classroom teachers. I remembered when it came time for each of my own children to choose a profession. How I waited to hear if any had plans to follow Mom into teaching. Long considerations held no mention of anyone becoming a teacher.

Dessert was being served, and everyone was still involved in the discussion of the enormous salary of one individual, when the phone rang. My husband handed the phone to me.

“Hello, this is Bonnie Block,” I said.

“Is this the Bonnie Block who used to teach kindergarten?”

A nervous sensation swelled in me, and my mind raced with memories of those days long ago.

“Yes!” I exclaimed with a lump in my throat. It seemed like forever as I waited anxiously to hear what the caller would say next.

“I am Danielle—Danielle Russ. I was in your kindergarten class.”

Tears of surprise and joy rolled down my flushed cheeks.

“Yes,” I uttered softly as I remembered that darling, wonderful child.

“Well, I am graduating from high school this year, and I have been trying to find you. I wanted you to know what a difference you made in my life.”

She proceeded to give details. My influence on her wasn’t limited to kindergarten but remained a strong motivating force when she needed a coach to help her meet a challenge. “I pictured you praising and encouraging me all the way.”

Why choose teaching?

The pay is great!

1.The author’s children were not willing to be a teacher as their profession because ________.

A. they didn’t like the profession

B. they would give a lot but gain a little

C. they wanted to try different careers

D. their mother rejected it

2.Danielle rang the author mainly to ________.

A. express gratitude

B. make complaints

C. keep in touch

D. show off her achievements

3.When the author received the call, she felt ________.

A. embarrassed but delighted

B. confused but pleasant

C. unexpected but moved

D. astonished but regretful

4.The last sentence “The pay is great!” implies that the author ________.

A. suffers a lot as a teacher

B. pays a lot for teaching

C. is well-paid as a teacher

D. has her work recognized
