Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the “tank test”. A modern airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (結(jié)構(gòu)) of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (壓力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (發(fā)動(dòng)機(jī)) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

By doing the “tank test”, the engineers can find out ___________.

A. the pressure inside and outside the plane               

B. the strength of the plane structure

C. the amount of air in the plane                              

D. the power of the airplane engines

What will happen to the plane under the “tank test”?

A. It will be broken.                                              

B. It will be made stronger.

C. It will be filled with water.                                         

D. It will be tested by pilots.

According to the text, why are test flights most dangerous?

A. The engines may be damaged.               

B. The pilot may lose control of the plane.

C. The plane may explode in the air.           

D. Too much air may get into the plane.

What might be the most suitable title for the text?

A. Two Important Tests on Airplanes                

B. The Danger of Testing Airplanes

C. The Importance of Flying Safely                  

D. How Airplanes Are Made and Tested

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩處為多余選項(xiàng)。
  1   First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built’, the ．containers used for the transport of the materials are not． 2 Unfortunately, both’ of these may have an effect on the general public, since they are sure to pass near, or even through heavily populated areas．
Second, there is the problem of waste．  3  It is impossible to make these wastes non—radioactive, and so they must be stored in one of the inconvenient ways ．that scientists have invented．For example? they may be buried under the ground, or dropped into deserted mines, or sunk in the sea．However, these methods do not ’solve the problem, since an earthquake could easily break the containers．
Third, there may occur the danger of a leak or an explosion at the power station．As with the other two dangers, this is not very likely to take place． 4  However, it can happen．
Separately, these three types of dangers are not a great cause for worry．  5 

A．It is unusual for radioactive materials to be transported across land．
B．There are three separate sources of danger in supplying energy by nuclear power．
C．All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years．
D．The general public are strongly against the nuclear program．
E．So it does not provide a serious objection to the nuclear program．
F．Normally, only two methods of transport are in use, namely road or rail．
G．But when they are taken together, the probability of disaster is extremely high．
