It seems to be strange to you there is a blind spot(點) 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 of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.

London has a new magazine. But it is not printed(印刷) on paper. Everyone who has a television can receive it because it is on TV.
In order to read this magazine you have to have a decoder (解碼器). Each page of it is numbered, so you only have to dial the number to choose which subject you want to read about. There are all kinds of information ---everything is included from cooking to the latest sports news.
If you want to read the news, the first thing you have to do is to turn to the back page, which has an easy-to-remember page number, 100 for example. Then you start choosing what you want to read. The news is on page 101 to 109, so you put in the numbers and the news appears written across your screen. Perhaps you want to go out in the afternoon, so you press 181, and a brightly colored weather map appears on the screen. But the weather is terrible, so you decide to go shopping and dial 162 for a list of the week’s best bargains. But should you drive or take the train? To answer that question you only have to press 189 for the traffic report. It is very simple to use. But probably the best thing about the service is that it is being updated all the time. Journalists type new material directly onto the screen and the whole pages of the magazine can be replaced in minutes.
London already has three services. One, sent out by TV, is called ORACLE while the other two, on BBC, are called CEEFAX because they let you see facts. Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized(宣傳). BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere. But many people would agree that is a breakthrough(突破) as great as the invention of printing, which could not just change our reading habits but our whole way of life.
小題1: We can know from the passage that in London        .
A.the magazine is available at any local home
B.most of the postmen will lose their jobs some day
C.everyone can read this magazine if they have a television
D.the readers can get various kinds of information staying at home
小題2:In the sentence “Each page of it is numbered,” the word “it” refers to the        .
A.magazine B.programC.decoderD.subject
小題3:According to the passage, the “decoder” is used to help people        .
A.work out the total(合計) of certain numbers
B.read the information sent by TV signals
C.go shopping and have other entertainment
D.receive some special TV program for entertainment
小題4:The passage is mainly about        .
A.a(chǎn) new magazine printed in London
B.a(chǎn)n up-to-date way of getting information
C.a(chǎn) popular TV program about magazines
D.a(chǎn)n advanced technology helping people communicate

Andrew Engel was puzzled. He was sitting in class, but had no idea what the other students were talking about. He had done his homework, paid attention to lectures, and taken notes, but nothing was familiar. “Everyone is so much cleverer than I am,” he thought. It was a strange feeling, as he was always a good student in high school.
He felt even more puzzled a few days later. He got lost on his way to his favorite cinema. What’s worse, he began having trouble finding the right words when speaking. He asked, “What’s for dinner, Mom?” after he had just eaten. Poor Andrew, he was only 15!
His parents were worried and took Andrew to see a doctor. A brain scan(掃描) made it clear: Andrew had a malignant brain tumor(惡性腦腫瘤) . It was pressing on the part of the brain that makes new memory. He should be operated on as soon as possible. Andrew was scared!
Doctors removed the tumor, but Andrew’s memory was still poor. He was told he would probably never go back to school. Andrew was eager to enter a university, but it seemed that his dream wouldn’t come true.
“Even though they told me this, I knew I wanted to go back to school,” Andrew said. “I wanted to get my memory back.”
Andrew began by auditing(旁聽) an English class at a nearby school. In class, he took notes carefully and read his notes several times a day, then typed them again and again. He studied twelve hours a day, seven days a week. He worked ten times harder than other students. In 2007, at age 29, he graduated from a local university. Six months later, Andrew found a job.
