15.The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you.Air pressure is a powerful force.When you swim underwater,you can feel water pushing on 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 for 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
Method
Check that the egg will sit firmly on the neck of the bottle.
Tear the paper into strips and put the strips into the bottle.
Light the paper by dropping a burning match into the bottle.
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 presses against the egg and then the egg is pushed into the bottle!This proves that air is all around and that it is pressing down on us.
28.The experiment is carried out to proveB.
A.water pushes on your body when you swim underwater
B.the pressure of air around us has a powerful force
C.the earth is surrounded by a layer of air called the atmosphere

A.The bottle could break.
B.The egg has to be perfectly placed on the neck of the bottle.
C.The egg needs to be shelled.
D.You need to light the paper with a match.
30.In the experiment,the burning inside the bottle canA.
A.finish up the oxygen inside the bottle
B.make a seal in the neck of the bottle
C.equalize the air pressure inside and outside
D.Produce more oxygen inside the bottle
31.How did the egg get into the bottle?C
A.The oxygen inside the bottle sucked the egg in.
B.It became soft without the shell.
C.The outside air pressure forced it into the bottle.
D.The neck of the bottle was wide enough. 试题答案

“What are you doing for Christmas?” said Nick with a smile that showed all his yellow teeth.
“I’m opening presents and having dinner with my ,” said Joy, trying to be polite. “What about you?”
“My parents are away,” he said. “I live with my uncle, who doesn’t like me very much.”
Joy wasn’t sure how to , so she said goodbye with an awkward smile. She felt sorry for Nick since he must feel . But that wasn’t really her problem.

After dinner, the family into their car and headed to church for the Christmas Eve service. When they walked into the old building, they were by the flow of beautiful songs. A man stood up with Bible and the story Joy had learned on her mother’s knee. It was about a baby named Jesus who came to live on Earth to help people who him.
