2、面临两种选择：广泛阅读还是关注专业书籍的阅读? 2.我的读书方法 （分数：30.00）_二、Part II Reading C(总题数：1，分数：71.00)The Institution of Marriage The Indians, as all other communities of human beings in every age, in every clime (地域), and in every possible condition in respect to civilization or barbarism, have done, lived in families. T

3、hat is to say, the husband, the wife, and the children formed a natural group and dwelt together in common. The children were under the care of themselves and the husband and wife, once joined, remained united for life. Some persons have imagined that the institution of marriage is an artificial ins

4、titution, adopted by society as an arrangement proved by experiment to be, on the whole, most advantageous to man. But the universality of this institution proves that it is of higher origin. It is a part of mans nature, considered as an animal, that he should have one female partner, and that the u

5、nion which binds him to his partner, when once she is chosen, should endure for life. It is curious to observe that the provision of nature by which man is led everywhere, and under all circumstances, to the institution of marriage as the foundation of the social state, is in accordance with a gener

6、al principle which pervades the whole animal creation. The principle is this: General Law of Pairing In all cases where the nurture of the young of any animal, for any reason, requires more than the mother herself alone can do for them, it seems to be a general law of nature in respect to such anima

7、ls that they are provided with instincts which lead them to pair. A male and female unite, and they remain united until the young no longer need their joint assistance. Thus birds pair, because it is necessary that both should co-operate to build the nest, and also that the father should bring food

8、while the mother sits upon the eggs to hatch them. And lions pair, for one must remain and take care of the young, while the other goes away on distant excursions to procure food. But sheep and other such animals do not pair, for their young do not require the joint attention of father and mother. I

9、n respect to the duration of the union thus formed, the principle is that it continues as long as the necessity for it continues; that is, as long as the brood of young ones require the united efforts of both father and mother to protect them. Then at least so it is supposed in the case of birds whe

10、n the season is over and the young ones are grown up to maturity, the union is terminated, the pair separate, and each, at the commencement (开始) of a new season, chooses a mate again. Application to the Case of Man Now, in the case of man, the young require the aid of both parents for their nurture

11、and protection; and inasmuch as each requires this attention for ten or twelve years at least, and as during the time while the first-born is attaining this age others succeed, the period during which the conjoined effort of the parents are required is protracted (拖延), without intermission, during t

12、he whole of their lives that is, through all the portion of it during which their natural vigor continues unimpaired. It follows from this, and from the fact that the numbers of the sexes are equal, that according to the analogy of nature we should have expected that the human species would be provi

13、ded with instincts leading them to unite in pairs, and to continue so united for life. We find, accordingly, that this is the fact everywhere. The marriage laws of all human societies are consequently made to guard and protect the marriage institution not to establish it. The institution itself is f

14、ounded in instincts and principles of our nature existing antecedent to all law. Indeed, the family institution, instead of waiting to be established by law, is often even more important and more prominent in low states of civilization than in high. It is most powerful where laws are weakest. Instea

15、d of being created by law and thus following it in the order or time, it is itself rather the origin and source of law. So far as we have any opportunity to trace back the forms of social organization to their source, we find them arising usually, in the first instance, from that primordial (原始的) an

16、d elementary bond, the union of husband with wife, which springs at once from the physical constitution and innate instincts of man, and is the germ from which all other systems of authority and subordination come. It was eminently so among the Indians. They lived in families throughout the length a

17、nd breadth of the land the families of the same connection being grouped together in tribes. They lived generally in peace, and were engaged in labors of patient industry for providing food and clothing for themselves and their children. （分数：71.00）(1).The Indians were different from other communitie

In the first place, television is not only a convenient source of entertainment, but also a (40) 5cheap one. They just sit comfortab

The television viewer needs to do nothing. (44) 9. Secondly, television keeps one informed about current events, allows one

There are many other arguments for and against television. The poor quality of its programmes is often criticized. Bu

38、e (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, theyre nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind som

39、ething as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid. A growing group of A1 researchers think they know where the field went wrong. The problem, the scientists say, is that Al has be

40、en trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in Al, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of the

41、se researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new natu

42、re-based Al movement is slowly but surely moving to the forefront of the field. Imitating the brains neural (神经的)network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. “People tend to tr

43、eat the brain as if it were made up of color-coded transistors,“ he explains, “but its not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves.“ Specifically, Conrad believes that many of the brains capabilities stem from the pattern-rec

44、ognition proficiency of the individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims, would be to build it around the same sort of molecular skills. Right now, the notion that conventional computers and software are fundamentally incapabl

45、e of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town. （分数：88.50）(1).The author says that the powerful computers of today _.（分数：17.70）A.are capable of relia
