  X-rays were first discovered by a German scientist, Wilhelm Konrad Rontgen, in 1895, almost by accident. He and several other scientists were experimenting with passing electric currents through certain gases in a special glass tube from which the air had been moved. One day Rontgen noticed that, even when the tube was covered with black paper, some strange kind of radiation was coming through and making a screen nearby glow. Rontgen could not see anything coming out of the tube, but then he discovered that if he put the screen in the next room on the other side of a closed door, the rays could pass not only through black paper but also through wood.

  The next thing he found out was that if he put his hand between the rays and a photographic plate , the rays would print a shadow of the bony framework of his hand on the plate. In fact , the rays could pass as easily through the fleshy part of his hand as through the black paper, but hardly at all through the bone. So Rontgen made the first X-ray picture of a hand, showing just how the bones in the hand fit together.

1.What puzzled Rontgen one day during his experiment was the.black-paper-covered tube.

2.The screen didn't stop glowing even when it was moved to the next room.

3.Rontgen put his hand between the rays and a photographic plate to stop the radiation.

4.The rays proved to be unable to pass through wood.

5.From the passage , we know X-rays are invisible.

閱讀下面短文,根據(jù)短文內(nèi)容回答問題。

  In the north of Scotland there is a lake called Loch Ness. It is the biggest lake in Britain. It is over thirty kilometers long and in places nearly 300 meters deep. It is cold and dark and not many people went there until after 1930. Then a road was made around the lake. Holiday makers began to use the mad, and this was when the stories began.

  Someone said that he had seen a monster in the lake. He said it was twelve meters long. It had a long neck and a small head. Then someone else said he had seen it. Others said the same thing and in 1933 a London doctor took a photo. It looked like a monster with a long neck and a thick body but the photo was not clear. The newspapers printed the picture and called it the Loch Ness monster, or “Nessie”.

  Then the argument began. Some people, however, were certain there was something living in the lake. Others said there was nothing there. 1n 1961, a lot of people joined together to make a real effort to see and photograph the monster if there was one! Several times people thought they saw something but after ten years there was still no real proof.

  Later underwater television cameras were used, but no one found any real proof. However, they did find something interesting: a huge underwater cave. It was big enough to be home of a monster, but of course , this was not a proof.

  In 1975, however, some American scientists formed a search group. They used an underwater camera. It took pictures every seventy seconds. Some of the pictures seemed to show a red-brown creature. Its body was about four meters long and had a very ugly head on the end of a four-meter neck. Many people then began to believe in the monster. But even today we cannot be certain.

1.Did many people go to Loch Ness Lake before 1930?

___________________________________________________________

2.What did the monster look like as people described in the 1930's ?

___________________________________________________________

3.Who first took a photo of the monster?

閱讀下面短文,根據(jù)短文內(nèi)容,判斷句子的正(T)誤(F)。

  I have a rule for travel: Never carry a map. I prefer to ask for directions (方向).

  Foreign visitors are often puzzled in Japan because most streets there don’t have names. In Japan, people use landmarks in their directions instead of street names. For example, the Japanese will say to travelers, “Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.”

  In the countryside of the American Midwest, usually there are not many landmarks. There are no mountains, so the land is very flat (平坦的). In many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distance. In Kansas or Iowa, for example, people will say, “Go north two miles. Turn east, and then go another mile. ”

  People in Los Angeles , California, have no idea of distance on the map:They measure distance by means of time, not miles. “How far away is the post office?” you ask. “Oh,” they answer, “It's about five minutes from here. you say, ”Yes, but how many miles away is it? They don't know.

  People in Greece sometimes do not even try to give directions because visitors seldom under-stand the Greek language. Instead of giving you the direction, a Greek will often say, “Follow me. ” Then he'll lead you through the streets of the city to the post office.

  Sometimes a person doesn't know the answer to your question. What happens in this situation? A New Yorker might say, “Sorry, I have no idea. ” But in Yucatan, Mexico, no one answers, “ I don’t know. ” People in Yucatan think that “ I don’t know” is impolite. They usually give an answer, often a wrong one. A visitor can get very, very lost in Yucatan!

  One thing will help you everywhere-in Japan, in the United States. In Greece, in Mexico, or in any other place. You might not understand a person’s words , but maybe you can understand his body language. He or she will usually turn and then point in the correct direction. Go in that direction, and you may find the post office!

1.The passage mainly tells us that there are different ways to give directions in different parts of the world.

2.In Japan, people use landmarks in their directions.

3.In Greece, people tell distance by means of time.

4.People in different places always give directions in the same way: they use street names.

5.Travelers can learn about people’s customs by asking questions about directions.

Saving the Past for the Future

  When people visit an archaeology site, or work on a site, they must remember that they are touching history. The artifacts and features they see are the only links to understanding the prehistoric people who once lived here. Since prehistoric people had no written records or diaries to leave behind, we are dependent upon the artifacts they did leave. Every artifact is like a piece of a puzzle; if even one piece is missing, the puzzle isn’t complete. Archaeologists are unable to understand a past culture and how people interacted with the environment if any of the evidence is missing or altered.

  The past human life that an archaeologist studies is a heritage that we all share. It is our re-sponsibility to respect and preserve this heritage by reporting archaeological finds to any archaeologist and not disturbing (not removing) archaeological sites.

  Help save the past for the future.

1.The things in an archaeology site are the reflection of history.

2.The artifacts and features we see are not the only links to understanding the past.

3.If any artifact is missing, it may bring the archaeologist a lot of trouble to understand the past culture.

4.Prehistoric people had written records or diaries to leave for the future.

5.If we protect the heritage , we are saving the past for the future.
