（B）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 matchMetheod1） 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.ResultAstonishingly, 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 happenedAs 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.
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.

共用题干第三篇Who Came First, the Chicken or the Egg?I just mailed the chicken and the egg,each in its own separate packaging,and kept careful track of when each shipment was sent from a post office in Cambridge, Massachusetts,and when it later arrived at its intended destination in New York City.In mailing the chicken,I was careful to adhere to the restrictions described in the American Postal Service's Domestic Mail Manual 57,as updated on April 3,2003.This,the most recent,version of the Manual states that:"Adult chickens must be sent by Express Mail.The containers used must pass the standards in International Safe Transit Association Test Procedure IA;be strong enough to endure normal handling;and ensure enough air for the chickens in transit...The number of birds must not be more than the container's limit."I mailed the chicken in a wooden box got from a colleague who does research with birds.Then,I mailed the egg in standard packaging obtained through an industrial supplier.It's quite simple.I posted both the chicken and the egg at 9:40 am,on a Monday morning,from the Harvard Square post office,in Cambridge,Massachusetts.The staff there told me that this was the first chicken anyone had mailed from there in recent memory,and perhaps ever.They handled both the chicken and the egg skillfully and politely.The intended destination for both packages was the James A.Farley General Post Office,which is located in Manhattan right next to the Penn Station train terminal.I took the subway from the Harvard Square to the Boston train station,and from there boarded a train to New York City,a distance of about 320 kilometers,arriving that afternoon at Penn Station.I immediately went to the post office,to await the arrivals of the chicken and the egg.The James A.Farley General Post Office is open 24 hours a day,so I was able to wait there until both items arrived.I inquired once per hour for both the chicken and the egg.That day,Monday,neither the chicken nor the egg arrived.The next day,Tuesday, neither the chicken nor the egg arrived.The chicken arrived at 10:31 am,Wednesday.The staff at the post office told me that this was the first chicken anyone had mailed to the post office in recent memory, and perhaps ever.The egg arrived that same day,at 9:37pm,11 hours after the chicken.Based on experiment data,it's now quite clear that the chicken came first,the egg second.How did he go to New York City?A:By boat.B:Bybus.C:Byair.D:By tube and rail.
