　　2022甘肃专升本英语阅读理解模拟题

　　Before a new airliner goes into service, every part of it is tested again and again. But there are two tests more important than all the others. One of them is verv strange and the other is very dangerous.

　　The first of these is called the "tank test". A modern airliner must fly at verv high altitudes. Air must he numped into the plane so that the passengers can breathe. The metal structure of the plane has to be very strong for this reason. When the plane is filled with air, or "pressurized", the air presses against the skin of the plane inside. The pressure on a small window, for example, is like a huge. giant foot that is trying to get out. If a small part of the plane were to crack, the plane would explode in the sky. This is what happened to the firs

　　Comets (彗星), In order to test the structure of the plane. it is lowered into a huge tank of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anvwhere else Engineers can discover which part of the nlane has cracked This part will be made stronger.

　　The most dangerous test happens when the new plane is going through test flight in the air. The test nilot must find out exactly what happens when the engines are all shut off at once He takes the plane up very high. Then he shuts the engines off. The plane begins to fall like a stone. It is the pilot's iob to find out how he gets control of the plane again. These two tests are examples of how planes are made safe hefore thev ever carrv passengers
