When I was a little girl, my brothers and I collected stamps for many years. My mother didn't use to work during the week, but she worked in the post office near our house on Saturdays, and she used to bring home all the new stamps as soon as they were issued.
On the day of the World Cup football final in London in 1966, we were very excited because England were playing West Germany in the final. When we were having lunch, my mother told us to go to the post office straightaway after the match if England won, but she didn't tell us why. At 2 o'clock my mother went back to work as usual, while the rest of the family were watching the football on TV at home. Although she wasn't watching the match, she was listening to it on the radio.
England won 4:2 and so my brothers and I ran to the post office. As we burst in, my mother was standing behind the counter. She was waiting to sell us a very special limited edition with ENGLAND WINNERS on each stamp. We were over the moon.

Every day, the news of the world is relayed to people by over 300 million copies of daily papers, over 400 million radio sets, and over 150 million television sets. Additional news is shown by motion pictures, in theatres and cinemas all over the world. As more people learn what the important events of the day are, fewer are still concerned exclusively with the events of their own household. As the English writer John Donne put it, nearly four hundred years ago, "no man is an island." This idea is more appropriate today than it was when Donne lived. In short, wherever he lives, a man belongs to some society; and we are becoming more and more aware that whatever happens in one particular society affects, somehow, the life and destiny(命运) of all humanity.
Newspapers have been published in the modern world for about four hundred years. Most of the newspapers printed today are read in Europe and North America. However, soon they may be read in all parts of the world, thanks to the new inventions that are changing the techniques of newspaper publishing.
Electronics and automation(电子和自动化)have made it possible to produce pictures and text far more quickly than before. Therefore, the publishing of newspapers and magazines becomes more economical.
Furthermore, photo-copies can be sent over great distances now by means of television channels and satellites such as Telstar. Thus, pictures can be brought to the public more quickly than previously.
1、People learn about what happens in the world through ____________.
A、newspapers and magazines
B、radio and television sets
C、electronics and automation
D、"newspapers and magazines" and "radio and television sets"
正确答案：D
2、According to the passage, the expression "no man is an island" means that ____________.
A、no man lives on an island surrounded by water
B、every man is in some way alone
C、every man can live an independent life
D、every man belongs to some society
正确答案：D
3、The passage suggests that newspapers have been published for about ____________.
A、100 years
B、200 years
C、300 years
D、400 years
正确答案：D
4、According to the author, people in today's world ____________.
A、have become more isolated than people in Donne's times
B、are affected more by whatever happens in the other parts of the world
C、are concerned only with the events of their own household
D、only read newspapers in Europe and North America
正确答案：B
5、Today the publishing of newspapers and magazines is more economical because ____________.
A、more people are engaged in newspaper publishing
B、new inventions are changing the techniques of newspaper publishing
C、Telstar can send pictures to any part of the world
D、the competition in newspaper publishing is getting severe

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, "I wonder why that woman doesn't wash her window. It really looks terrible."
One bright morning I decided to clean my flat, including washing the window on the inside.
Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!
Then it dawned on me. I had been criticizing (批评) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?
Since then, whenever I wanted to judge (评判) someone, I asked myself first,"Am I looking at him through my own dirty windows?" Then I try to clean the window of my own world so that I may see the world about me more clearly.

On Sunday morning a strong earthquake hit Indonesia and then big tsunamis(海啸) followed. They soon went on to other countries in South and Southeast Asia as well as East Africa.
Tsunamis are especially dangerous for children. By Wednesday, nearly 60,000 people died because of the tsunamis. One third of them were children, and most of them were 5 to 12 years old.
In many Asian countries near the sea, poor kids(小孩子) helped their parents fish. So they were in danger when the tsunamis came.
In Sri Lanka, when the first waves hit, thousands of children came to the seaside. The waves brought in fish. The old and the young collected them. Many people waited for more. Then tsunamis six metres high hit the island with 19 million people.
“They got caught and could not run to safety. This is the reason why so many children have died,” said a police spokesman in Sri Lanka.
In open seas tsunamis are only one or two metres high. When they are near land, they are as high as six or seven metres. Houses and cars near the sea can be taken away by these big waves. Because tsunamis move fast and can travel to another side of the sea within one day, they may affect(影响) a lot of places.
The Pacific Ocean(太平洋) has a lot of strong tsunamis because of the size of the ocean and large earthquakes there. China doesn’t see tsunamis often because its sea floor is quite flat(平的). Islands around China also help the country avoid(避免) from them.
What should you do when there’s a tsunami? Move to a safe place. If you are near the sea and you feel the earth shake, move to a piece of higher ground. Stay away from rivers and streams(溪流).
1、Which places did the big tsunamis hit?
A、All the seaside countries.
B、South and Southeast Asia as well as East Africa.
C、Only Indonesia and Sri Lanka.
D、China and Vietnam
正确答案：B
2、Which of the following statements is WRONG?
A、In open seas tsunamis are one or two metres high.
B、Sri Lanka has a population of 19,000,000 children
C、 Most of the children who died in tsunamis were 5 to 12 years old.
D、Tsunamis are especially dangerous for children.
正确答案：B
3、Many children were killed in tsunamis because________ .
A、they played happily near the sea and fell into it carelessly
B、sharks appeared and ate them
C、they were too young and weak to run to safety
D、they could not swim fast enough to get to safe places
正确答案：C
4、Why doesn’t China see tsunamis often?
A、Because of the size of the ocean.
B、 Because of large earthquakes
C、Because its sea floor is quite flat, and those islands around also help it avoid from tsunamis.
D、Because its coastline is very long.
正确答案：C
5、Because its coastline is very long.
A、Listen to a weather report.
B、Run to your parents for help.
C、Get to a safe place as soon as possible
D、Keep it away as quickly as required.
