2017年職稱英語閱讀理解模擬題及答案理工B

  Mind-reading1 Machine

A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what's happening in their brains.

When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons are responsible for this processing.

The fMRI (functional Magnetic Resonance Imaging ) 2 brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.

Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize3 which parts of the brain receive more oxygen-rich blood--and therefore, which parts are working to process information.

An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.

The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.

In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.

  詞彙

scan v. &n. 掃描 visualize v. 使可見;設想

neuron n. 神經元

  註釋:

1. Mind-reading: 能讀出(猜出)人的想法的。mind-read: 可做動詞,如,As a successful

salesman, he is able to mind-read his customers.

2. FMRI (functional Magnetic Resonance Imaging) : 功能性磁振造影。這是一種新興的神經影像學方式,其原理是利用磁振造影來測量神經元活動所引發之血液動力的改變。

3. visualize: 意為make(something)visible to the eye,即“使可見,使顯現”。

  練習:

1. What is responsible for processing the information sent by your eyes?

A)A small region of the brain.

B)The central part of the brain.

C)Neurons in the brain.

D)Oxygen-rich blood.

2. Which of the following statements is NOT meant by the writer?

A)Ceils in your brain are called neurons.

B)The more oxygen a neuron consumes, the more blood it needs.

C)FMRI helps scientists to discover which parts of the brain process information.

D)fMRI helps scientists to discover how the brain develops intelligently.

A)The Recent Development in Science and Technology.

B)Your Thoughts Can Be Scanned.

C)A Technological Dream.

D)A Device that can Help You Calculate.

  答案與題解:

1. C 文章第二段的最後兩個句子提供了答案。Cells in your brain called neurons are

responsible for this processin9.這裡的processin9指的就是上句中的內容。

2. D 的電容文章中沒有出現。A的內容在第二段可找到。B的內容在第二段可找到。C的內容在第五段可找到。

3. A highlight:使…顯得突出,標出。at work:正在工作的。這裡指正在處理資訊的'(大腦區域)。

4. B答案在文章的第六段中可以找到。實驗者讓兩個自願受試者觀看許多照片,並用fMRI對裝置測試他們的大腦在這一過程中的活動。

5.B A論述的範圍太大。fMR技術已不再是夢想,所以C也不是正確選擇。D所述內容與

文章完全不符。B符合文章內容,是最佳選擇。

  譯文:

  讀心機

一個加州的研究團隊開發了一種可以通過掃描人體大腦所發生的變化從而預測出這個人正在看一些什麼樣的物體的方法。

當你注視一些物體時,你的眼睛會發送一個關於該物體的訊號到你的大腦中。大腦的不同區域處理眼睛傳送的這些訊號。大腦中負責這個過程的細胞叫做神經元。

FMBI(功能性磁振造影)腦掃描可以大體地比較大腦中人們對所觀察物體基本形狀的電運動。

像身體中其他地方的細胞一樣,活躍的神經元細胞也需要氧氣。血液為神經元提供氧氣,神經元越活躍,對氧氣量的需求越大。大腦中越是活躍的區域,它的神經元也就越活躍,為此,更多的血液會流經這一區域。那麼通過使用FMBI,科學家可以使大腦中接收相對多的富氧血液的部分視覺化。因此,視覺化的部分就是處理資訊的部分

FMRI機是一種可以掃描大腦和測量流向大腦的血液變化的裝置。這項技術為研究者顯示,當人們思考觀察進行像說話閱讀這樣的活動時,大腦運動的變化。通過突出顯示人們觀看不同影象時頭腦工作的區域,FMRI可以幫助科學家們確定與不同影象相關的大腦活動的具體形式。

加州的研究者讓兩個志願者觀察數百個諸如人、動物和水果這樣的日常事物。他們用這樣方式來測試大腦的活動。科學家使用FMRI機來記錄志願者看每一張圖片時大腦的活動。顯示這一活動時,不同物體會使志願者大腦的不同區域在掃描時亮度增加。科學家利用此資訊來建立一種模式去預測大腦對所看到事物可能如何反映。

在第二個測試中,科學家讓志願者看120個新影象。和以前一樣,他們每看一張新影象時大腦都被掃描一次。這次,科學家用他們的模式來比較FMRI掃描的影象。例如,如果影象在第二次測試顯示相同的形式的大腦活動,同時,該腦活動與在第一次測試中蘋果圖片有大關聯,那麼這個模式可能會預測出志願者們正在看一些蘋果。
