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 modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构) 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 (压力) 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(发动机) 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 amount of air in the plane
B.the strength of the plane structure
C.the pressure inside and outside the plane
D.the power of the airplane engines

Never use any drug unless there is a good reason, especially for the woman who is expecting a baby. Ask the patient if he has had previous drug reactions: if he has, be careful. It is estimated that more than half of the adverse reactions that are reported would be prevented if this were done. Ask the patient ff he is already receiving other drugs.
If possible, use a drug with which you are familiar. If you use a new drug, be especially on the watch for adverse reactions. Report serious or unusual reactions suspected as due to established drugs, and any reaction however slight that may be due to a newly marketed drug.
This is a set of recommendations for ______.
A.doctors prescribing for patients
B.doctors training people who take drugs
C.drug companies
D.persons who sell drugs

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory. As philosopher of science, Karl Popper has emphasized a good theory is characterized by the fact that it makes a number of predictions that could in principle be disproved or falsified by observation. Each time new experiments are observed to agree with the predictions the theory survives, and our confidence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory. At least that is what is supposed to happen, but you can always question the competence of the person who carried out the observation.
In practice, what often happens is that a new theory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newton's theory of gravity. Einstein's general theory of relativity predicted a slightly different motion from Newton's theory. The fact that Einstein's predictions matched what was seen, while Newton's did not, was one of the crucial confirmations of the new theory. However, we still use Newton's theory for all practical purposes because the difference between its predictions and those of general relativity is very small in the situations that we normally deal with. (Newton's theory also. has the great advantage that it is much simpler to work with than Einstein's ! )
It turns out to be very difficult to devise a theory to describe the universe all in one go. Instead, we break the problem up into bits and invent a number of partial theories. Each of these partial theories describes and predicts a certain limited class of observations, neglecting the effects of other quantities, or representing them by simple sets of numbers. It may be that this approach is completely wrong. If everything in the universe depends on everything else in a fundamental way, it might be impossible to get close to a full solution by investigating parts of the problem in isolation. Nevertheless, it is certainly the way that we have made progress in the past. The classic example again is the Newtonian theory of gravity, which tells us that the gravitational force between two bodies depends only on one number associated with each body, its mass, but is otherwise independent of what the bodies are made of. Thus one does not need to have a theory of the structure and constitution of the sun and the planets in order to calculate their orbits:
Today scientists describe the universe in terms of two basic partial theories-the general theory of relativity and quantum mechanics. They are the great intellectual achievements of the first half of this century. Unfortunately, however, these two theories are known to be inconsistent with each other-they cannot both be correct. One of the major endeavours in physics today, is the search for a new theory that will incorporate them both-a quantum theory of gravity. We do not yet have such a theory, and we may still be long way from having one, but we do already know many of the properties that it must have.
According to the passage, why can't any physical theory be permanently established?
A.Such a theory is only suggested as a possible way of explaining an idea.
B.The person proposing such a theory may be incompetent.
C.Observations always disagree with predictions.
D.Observations are always falsified by predictions.

A company has a business application that provides its users with many different reports:receivables reports, payables reports, revenue projects, and so on. The company has just purchased some new, state-of-the-art, wireless printers, and a programmer has been assigned the task of enhancing all of the reports to use not only the company‘s old printers, but the new wireless printers as well. When the programmer starts looking into the application, the programmer discovers that because of the design of the application, it is necessary to make changes to each report to support the new printers.Which two design concepts most likely explain this situation?()
A.Inheritance
B.Low cohesion
C.Tight coupling
D.High cohesion
E.Loose coupling
F.Object immutability
