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.

For a few excited days last week, however, it seemed as if the whole world was a cancer patient and that all humankind had been granted a reprieve(痛苦减轻) . Triggered by a front-page medical news story in the usually reserved New York Times, all anybody was talking about--- on the radio, on television, on the Internet, in phone calls to friends and relatives----was the report that a combination of two new drugs could , as the Times put it, “cure cancer in two years.” In a matter of hours patients had jammed their doctors’ phone lines begging for a chance to test the miracle cancer cure. Cancer scientists raced to the phones to make sure everyone knew about their research too, generating a new round of headlines. The time certainly seemed ripe for a breakthrough in cancer. Only last month scientists at the National Cancer Institute announced that they were halting a clinical trial of a drug called tamoxifen (他莫昔芬) ------ and offering it to patients getting the placebo(安慰剂) -----because it had proved so effective at preventing breast cancer (although it also seemed to increase the risk of uterine(子宫的) cancer). Two weeks later came the New York Times’ report that two new drugs could shrink tumors of every variety without any side effects whatsoever. It all seemed too good to be true, and of course it was. There are no miracle cancer drugs, at least not yet. At this stage all the drug manufactures can offer is some very interesting molecules, and the only cancers they have cured so far have been in mice. By the middle of last week, even the TV talk-show hosts who talked most about the news had learned what every scientist already knew : that curing a disease in lab animals is not the same as doing it in humans. “The history of cancer research has been a history of curing cancer in the mouse,” Dr. Richard Klausner, head of the National Cancer Institute, told the Los Angeles Times. “We have cured mice of cancer for decades---and it simply didn’t work in people.” 第11题：According to the passage, a person suffering from cancer will A．give up any hope. B．pray for the health of his loved ones. C．seize every chance of survival. D．go out of his way to help others.
