Look at the centre circles of Diagram (图)A and Diagram B. Which of the centre circles looks larger? 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(解读)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(视觉错误)”.

Movie makers often make use of visual 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 visual illusions.

A.something is wrong with our eyes

     Talking on a mobile phone is expensive, so a lot of people send text messages. Text messages are
much cheaper by making the words shorter. You can do this by taking out "unimportant" letters in the
words and using numbers instead of words (2=to, 3=free, 4 = for, 8 = ate, so, etc. ). You can also keep
a way from using punctuation. Here is an example: Do u wnt 2 g 2 th cnma tnit? (Do you want go to the
cinema tonight?)
     What do you think these text messages mean?
     Whr hv U bn? Iv bn wing hrs fr a cll.
     Im hm nw, why nt gv me a cll.
     I gt a txt mssge frm my frnd. Shes hvng a prty on Strdy.
     Mobile phone users have developed a group of symbols to show how they feel. They are called
emoticons, and there are some examples below. To read an emoticon, you have to look at it sideways.
For example, if you say something in a text message that is a joke, you can follow it with a smiling face.
Like this :
     Why didt you call me? I'm so sad.- (Here are some others. Can you think of text messages where
you could use them? -) laughing, -( sad,  -< really sad,  -o shocked,  -v shouting,  | . | asleep,  8-| , 
surprised,  /\-o  bored.

A. Because they are expensive.
B. Because they are cheap.

A. one

4. Why do people use emoticons?
