单选题 Directions: There are 6 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.{{B}}Passage One{{/B}} The table before which we sit may be, as the scientist maintains, composed of dancing atoms, but it does not reveal itself to us as anything of the kind, and it is not with dancing atoms but a solid and motionless object that we live. So remote is this "real" table--and most of the other "realities" with which science deals--that it cannot be discussed in terms which have any human value, and though it may receive out purely intellectual credence it cannot be woven into the pattern of life as it is led, in contradistinction to life as we attempt to think about it. Vibrations in the either are so totally unlike, let us say, the color purple that the gulf between them cannot be bridged, and they are, to all intents and purposes, not one but two separate things of which the second and less "real" must be the most significant for us. And just as the sensation which has led us to attribute an objective reality to a nonexistent thing which we call "purple" is more important for human life than the conception of vibrations of a certain frequency, so too the belief in God, however ill founded, has been more important in the life of man than the germ theory of decay, however true the latter may he. We may, if we like, speak of consequence, as certain mystics love to do, of the different levels or orders of truth. We may adopt what is essentially a Platonist trick of thought and insist upon postulating the existence of external realities which correspond to the needs and modes of human feeling and which, so we may insist, have their being is some part of the universe unreachable by science. But to do so is to make an unwarrantable assumption and to be guilty of the metaphysical fallacy of failing to distinguish between a truth of feeling and that other sort of truth which is described as a "truth of correspondence," and it is better perhaps, at least for those of us who have grown up in an age of scientific thought, to steer clear of such confusions and to rest content with the admission that, though the universe with which science deals is the real universe, yet we do not and cannot have any but fleeting and imperfect contacts with it ; that the most important part of our lives-our sensations, emotions, desires, and aspirations-takes place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.

单选题In bringing up children, every parent watches eagerly the child's acquisition(学会)of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities , he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality(道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach(说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
