Look at the centre circles of Diagram (圖)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 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.
【小題1】Why does the centre circle in Diagram A look smaller than that in Diagram B?

A．something is wrong with our eyes
B．the two circles are not the same size
C．our brains interpret the information in a wrong way
D．the two pictures change quickly from one to the other
【小題2】What do movie makers make use of visual illusions for ?
A．To help the actors look better
B．To make the actors much braver
C．To help the actors become stronger
D．To make the actors seem different in size
【小題3】In the picture below, it seems that Line AB is shorter than Line CD, but in fact Line AB is as long as  Line CD. Which paragraph can explain what has happened to our eyes?
A. The second one.               B. The third one.
C. The fourth one.                D. The sixth one.
【小題4】What’s the right order according to the passage?
a. We look at things with our eyes.
b. Our brains interpret the messages.
c. Our brains tell us what we have seen.
d. Our eyes send messages to our brains.
A．a(chǎn) d b cB．c a b dC．a(chǎn) c d bD．b c a d
【小題5】Where may this passage be from?
A．A letter B．An English newspaper
C．A science bookD．An advertisement


【小題1】C
【小題2】D
【小題3】C
【小題4】A
【小題5】C

閱讀理解。
     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. Do you want to come?
B. Do you wear two caps?
C. Do you want two cakes?
D. Do you go home early?
4. Why do people use emoticons?
