　　It seems to be strange to you there is a blind spot on the eyes. Here is an
interesting experiment that can make something disappear, when one eye is open.
Make a card about the size of a postcard and write two English letters L and R
on it, L on the left and R on the right. First, hold the card about 80 cm away and
you see both the letters. Then close your right eye and look at the letter R only
with your left eye. And now, as you move the card slowly towards you, you'll
find the letter L disappearing. But if you move the card nearer to your face, the
letter will be seen again. Now do the same experiment with your left eye closed,
you'll find the letter R disappearing.
　　Why does the letter disappear? It is because there is a blind spot on the eye.
When the image (影像) of the letter falls on the blind spot, it won’t be seen. That
is why either of the letters disappears.
1.The writer of the passage thinks that _____ there is a blind spot on the eye.
A. few people know
B. no one knows
C. most people know
D. all the people know
2. "a blind spot" in the passage means _____ in Chinese.
A.污點(diǎn)
B. 消散
C. 盲點(diǎn)
D. 遺失
3. You fail to see the letter L in the experiment because _____.
A. your eyes are poor
B. its image falls on the blind spot
C. you move it close to your eye
D. your left eye is not open
4. In which order (順序) should you do the experiment?

　　Dear Sir or Madam，

　　Last Thursday，I traveled on the 8：00 a．m．train from Glasgow to London

King’s Cross and I was quite angry with the service of your company．

　　The train didn’t come on time and it was forty minutes late when it left Glasgow．

A man at the station said sorry to us，but he didn’t give us any reasons for the delay(誤點(diǎn))．We then had further delays on the way and had to wait another thirty minutes．As a result，I missed my plane from London to Frankfurt and had to wait for several hours.

　　What’s more，the service on the train was also very poor．The trip took more than five hours．Unluckily，we could buy nothing but some soft drinks on the train．Worst of all，something was wrong with the air conditioning(空調(diào)系統(tǒng)) and it got hotter and hotter in the train．Before we reached King’s Cross，the temperature was over 40℃．

　　Because of your poor service，I feel you should pay me compensation(賠償)．

　　I am looking forward to hearing from you．

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Yours faithfully，

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 David Robertson
