Literature is a means by which we know ourselves. By it we meet 【M1】______
future selves, and recognize past selves; against it we match our present self,
Its primary function is to validate and re-create the self in all its individuality
and distinctness. In doing so, it cements a sense of relationship between the
self and the otherness of the book, and allows us a notion of ourselves as
sociable. Its shared knowledge is vicarious experience; by this means we
enlarge our understandings of what it means to be human, of the corporate 【M2】______
and independent nature of human society. The act of reading the book marks 【M3】______
both our difference in and our place in the human fabric. The more we read,【M4】______
the more we are. In the act of reading silently we are alone from the book,【M5】______
separate from one's own immediate surroundings. Yet in the act of reading 【M6】______
we enter other minds and other places, enlarge our dialogue with the world.【M7】______
Thus paradoxically, while disengaging from the immediate we are increasing
its scope. In silence, reading activates a deeply creative function of consciousness.
We are deeply committed to the narrative which we coexist while 【M8】______
engaged in reading. All kinds of present physical discomfort ness may be 【M9】______
unnoticed while we are reading, and actual time is replaced by narrative time.
To imaginatively enter a fictional world by reading it is then both a liberation【M10】______
from self and an expansion of self.

It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful hits,
The only solid piece of scientific truth abut which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th. century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.
But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can' t be answered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.
According to the author, really good science ______.
A．would surprise the brightest minds of the 18th century Enlightenment
B．will help people to make the right choice in advance
C．will produce results which cannot be foreseen
D．will bring about disturbing results

Experts predict that China's healthcare market will have an annual growth of 6 to 8 per cent in the next few years, making it one of the potentially most prosperous. In Shanghai, annual medical expenditure is estimated to be 16 billion yuan (U.S. 93 billion). With an increasingly【B1】population, the growing consumption power and longer life【B2】of local residents, the medical market has great opportunities.
However, limited medical resources cannot meet people's needs【B3】financial deficits in State-owned hospitals.【B4】, there is room for a range of different medical organizations.
As is the case with many State-owned enterprises, public hospitals in the past half century have learned a lot of bad habits:【B5】management, over-staffing and bureaucratic operating procedures.
Being a member of World Trade Organization (WTO), China has to【B6】its promise to open the health industry to foreign capital in coming years. By then, public hospitals will be facing fierce competition from Western giants they have never prepared for.
So it's quite urgent【B7】them to learn how to operate as an enterprise and how to survive in the competitive market economy of the future.
As a【B8】, the healthcare sector was first opened to domestic private investors. Since the first private hospital opened in 1999, private investors from Shenzhen, Sichuan and Zhejiang provinces have been scrambling to enter Shanghai.【B9】show that about 20 private hospitals have been set up in the city, although this number,【B10】with more than 500 public hospitals, is still quite low.

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.
