237 West Palmdale Boulevard Fresno , Califormia93706 AmToy Corporation Suite 15 TransAm Building November 20, 2008 Dear Sirs, As a concerned parent, I am writing to protest your recent advertisement for Electro—Rain seen in local media is California. So Schally, I am referring to newspaper and magazine ads （attached this letter） and had the week of November 15. Children to your type of advertising in an immature way; that they shamble to understand how expensive some toys are for middle-class parent. Further, you product is violent in nature. Youth advertisement gives children the impression that it’s fine to have “two guns and laser eyes.” You also suggest that children need your toy protect them “when you go outside.” This is not a healthy attitude for children to have. I hope you will stop advertising your product in such a way that may our children. Sincerely yours, （Mrs. ） Alma Hernandez Enc |

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.
1.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.
2.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
3.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.
4.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.
