Question

Look at the center circles of Diagram (圖) A and Diagram B.  Which of the centre circles looks larger? 

Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.

Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time. 

"What's happening? Is something wrong with my eyes?" You may wonder at what you see. Don't worry. Here is how it goes:

When we look at things, our eyes send messages to our brains and then our brains interpret (解讀) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (視覺錯誤). 

Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.

A．help the actors look better

B．make the actors much braver

C．help the actors become stronger

D．make the actors seem different in size

【答案】

1.C

2.A

3.D

4.C

5.B

【解析】

試題分析：這篇文章講述的是在某種情況下，同樣尺寸的東西看起來確實不一樣的，人們把這稱作視覺錯誤。

1. 細節題。根據文章When we look at things, our eyes send messages to our brains and then our brains interpret (解讀) the information. However, sometimes our brains interpret the received information in a wrong way.可知，圖一中間的圓形看起來比圖二中間的圓形要小，是因為我們的大腦錯誤的解讀了這個信息。故選C

2.細節題。根據文章可知，我們的眼睛先看東西，然后眼睛看到的信息發送給大腦，大腦解讀了這些信息之后，告訴我們看到了什么。故選A

3.細節題。根據文章Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual.可知，電影制作商利用錯覺效果使演員看起來與平時的身材不同。故選D

4.細節題。文章第五段給我們解釋了為什么同樣尺寸的東西看起來不一樣的原因。故選C

5.主旨題。這篇文章主要講述的是為什么同樣大小的東西會看起來不一樣。所以，很可能是來自一本科學書。故選B

考點：科普類說明文

點評：本文文章不長很好理解，對于此類題目。學生在答題中首先要將文章讀懂，在問題中理解作者所提出的問題和文章的那部分對應起來，然后在綜合作答，總體來說，只要文章理解了，難度都不大。注意主旨題需要對總起段落進行理解，結合選項利用排除法作答。
