It seems to be strange to you that there is a blind spot (盲點)on the eyes. Here is an interesting experiment (實驗) 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 eyes. 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.
小題1:The writer of the passage thinks that ________ there is a blind spot on the eyes.
A．few people know
B．no one knows
C．most people know
D．a(chǎn)ll the people know
小題2:The word “disappear” in the passage means ________ in Chinese.

小題3:You fail to see the letter L in the experiment because ________.

D．you move it close to your eye
小題4:In which order (順序) should you do the experiment?

③Close your right eye
④Write two English letters
⑤Look at the letter R
⑥Make a card

小題5:The passage mainly (主要) tells us ________.

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.

With more and more farmers working in big cities, their children go into the cities, too.However, problems appear. One of these problems is that is difficult for these children to receive education in cities.
Luckily, there are some free schools for them, but they are not enough. Ten-year-old Li Xin is one of the lucky girls who get a chance to study in one of these schools. She is very happy.

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbooks (平裝本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全書), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books, science textbooks, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
小題1:It can be inferred from the passage that ____.
A．Fewer and fewer people will buy books.
B．A good dictionary should be kept in every home.
C．Books with hard covers sell better than paperbooks.
D．More people like TV programs about famous men.
小題2:What does the sentence “Television has not killed reading, however.” underlined in the second paragraph suggest?
A．People only need reading, though.
B．Reading is still necessary today.
C．Reading is more fun than television.
D．Watching television doesn’t help reading.
小題3:What can we learn from the passage?
A．TV programs are a chief provider of knowledge.
B．Cinemas are the best choice in getting information.
C．Reading is cheap way of learning and having fun.
D．Newspapers are an expensive way to enjoy oneself.
