Reading about history is nice, but finding ties to long-ago historical events in your own backyard is really exciting.

In their heavily populated area, neighbors Adam Giles,13, and Derek Hann.12, uncovered pieces of glass that looked quite different from what’s used today. “After digging about two feet down, I came across an interesting bottle,” Derek said. The bottle had a “pontil scar” on the bottle, an indication that it was hand-blown rather than machine made. It also had the name “Fraser” on one side.

Adam found remains of a green bottle and some very thick brown glass—again, far different from today’s.

After doing research on the computer, the boys contacted Aimee Wells of the county’s Cultural Resources office. She showed them a computer program that digitally puts old maps over modern satellite photographs.

 Bingo! Their back yards were once part of a military（军事的） encampment（营地） called Camp Alger used by Ohio soldiers on their way to fight in the Spanish-American War in 1898.

So how do a few bottles get connected to a brief war that was more than a century ago? “We get there by good judgment,” Wells said. “We know the time period of the bottles and what happened in that area.” Anyone can dig a hole, but archaeologists seek a deeper understanding. How do objects found relate to things around them?

When Derek and Adam realized that a solider might have held that Fraser bottle 110 years ago, they wondered what he might have been thinking. What did he see as he looked around him? How did he pass the time waiting to go into battle?

Historical records show that while waiting for orders, the soldiers in and around Camp Alger played baseball, played instruments and walked seven miles to the Potomac River once a week for baths. A spread of strange fever forced the closing of the camp, and there are no buildings to study. “What’s left is only what’s in the ground,” said Wells.

Derek’s and Adam’s back yards have joined the 3,400 places listed on the county’s register of archaeological sites. The boys were given tips on how to dig effectively and safely, and on how to document the location of items found.

The official record of their finds serves as another piece of the puzzle for historians seeking to form a more complete story of what happened.

 “Not everyone is going to have historical objects in their own yard,” Wells said. “That’s okay. Make your own time capsule and bury it. What would you want people to know about your life years from now?”

A. How Adam Giles and Derek Hann dug out the remains of an ancient military encampment.

B. What Adam Giles and Derek Hann found in their back yard and its relationship with an encampment.

C. The great contribution Adam Giles and Derek Hann made to the cause of archaeology.

D. The tips on how to dig out ancient objects buried under the ground safely and effectively.

that_______.

A. they have established the ties to Camp Alger by finding out the time period of the bottles.

B. they have figured out how to get to the place where the brief war happened.

C. they have managed to dig out the bottles in the back yard safely with common sense.

D. they were able to locate the soldiers who used the Fraser bottles 110 years ago.

Which of the following fits the description of historical records?

The people below travel abroad. Read the following stories and decide what problem each traveler experienced while traveling.

1._______ David got lost in an isolated place. To make matters worse, he had an accident and couldn’t walk freely. So he was in great need of timely help.

2._______ Paul had to buy a hamburger and ate it in the park instead of eating his mother’s delicious chicken, with which he couldn’t go through the customs.

3._______ Ann was stopped at the customs because she was carrying drugs without a doctor’s prescription. How regretted she was not to have done that!

4._______ Sally offended some of the people in the town she was visiting by wearing inappropriate clothes. She should have found out about local customs and followed them.

5.______ Jack didn’t obtain a transit card when he changed planes an airport, which made him very worried. There was no doubt that he was not allowed to get on board.

A．My mother was worried about me. She cooked me all my favorite dishes and put them into a box to take with me on my journey. But the customs officer inspected all the plant and animal products at the airport. Unfortunately it was illegal for me to bring into the country the kind of food my mother had given me and so it all had to be thrown away.

B．It was very hot so I put on some shorts and a T-shirt to go sightseeing. I hadn’t gone very far when I found everyone was looking at me, and they didn’t seem friendly to me. One woman even spat on me as I walked past. I decided to get off the crowded streets and so I turned down a small, quiet street.

C．During the four-day walking tour, I was amazed by mountain scenery and the ancient ruins we passed on our hike. On the last day, we arrived at the ruins of Machu Picchu in time to see the sunrise over the Andes. I spent the day visiting the ruins of that ancient Inca city before catching the train back to the capital city of the country.

D．When I got off the plane at the first airport. I saw someone handing out cards to some of the passengers, but I didn’t know what they were for, so I didn’t take one. When I tried to board the second plane they asked for my transit card, which I didn’t’ have. I was worried they were going to send me back to London.

E. I had been walking for about an hour when suddenly I slipped and fell down a riverbank. I hurt my ankle and couldn’t stand up. I didn’t know how I could get back to the village. I hadn’t told anyone what I was going, so no one would know where to look for me when they realized I was missing.

F. When I arrived at my destination, a customs officer at the airport looked in my bag and found the pills in a small box. He wanted to know what the pills were for and why they weren’t in their proper bottle with my name and the doctor’s name on it. I explained that the bottle had been too big and heavy. Then he wanted to know if I had a letter from my doctor explaining about the pills.

The surprising experiment I am about to describe proves that air is all around you and that it proves down upon you. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.

The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now foe the experiment！

What you need

?A hard-boiled egg without the shell

?A bottle with a neck slightly smaller than the egg

?A piece of paper

?A match

Metheod

1） Check that the paper will sit firmly on the neck of the bottle.

2） Tear the paper into strips and put the strips into the bottle.

3） Light the paper by dropping a burning match into the bottle.

4） Quickly sit the egg on the neck of the bottle.

Result

Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

Why it happened

As the paper burns, it needs oxygen and uses up the oxygen （air） in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! The proves that air is all around and that it is pressing down on it.

60. Why is there the need to take care when you are doing the experiment?

A. The bottle could break.

B. You need to light the paper with a match.

C. The egg needs to be shelled.

D. The egg has to be perfectly placed on the neck of the bottle.

61. In the experiment, the burning inside the bottle can___.

A. equalize the air pressure inside and outside

B. make a seal in the neck of the bottle

C. finish up the oxygen inside the bottle

D. produce more oxygen inside the bottle

62. How did the egg put into the bottle？

A. The oxygen inside the bottle sucked the egg in.

B. It became salt without the shell.

C. The neck of the bottle was wide enough.

D. The outside air pressure forced it into the bottle.

63. The experiment is carried cut to prove ______.

A. water pushes on your body when you swim underwater.

B. the earth is surrounded by a layer of air called the atmosphere.

C. the pressure of air around us has a powerful force.

D. the air pressure is not equalized around us.
