单选题At least since the Industrial Revolution, gender roles have been in a state of transi tion. As a result, cultural scripts about marriage have undergone change. One of the more obvious (46) has occurred in the roles that women (47) . Women have moved into the world of work and have become adept at meeting expectations in that arena, (48) main taining their family roles of nurturing and creating a(n) (49) that is a haven for all family members.

Probably the most significant change in men's roles, however, is in the emotional (54) of family life. Men are increasingly (55) to meet the emotional needs of their families, (56) their wives.

单选题{{B}}Passage Three{{/B}} Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and, more recently, rubber and plastic. And that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery. The tool is the laser and it is, being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: Light Amplification by Stimulated Emission of Radiation. As we all know, light is hot; any source of light--from the sun itself down to a humble match burning--will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams have shown researchers that different energy sources produce beams that have a particular effect on certain living cells. It is possible for eye surgeons to operate on the back of the human eye without harming the front of the eye, simply by passing a laser beam right through the eyeball. No knives, no stitches, no unwanted damage--a true surgical {{U}}wonder{{/U}}. Operations which once left patients exhausted and in need of long periods of recovery time now leave them feeling relaxed and comfortable. So much more difficult operations can now be tried. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but more effective. Altogether, tomorrow may see more and more information coming to light on the diseases which can be treated medically.

单选题Agreeable to your request, I send you my reasons for thinking that our northeast storms in North America begin first, in point of time, in the southwest parts: that is to say, the air in Georgia, the farthest of our colonies to the Southwest, begins to move southwesterly before the air of Carolina, begins to move southwesterly before the air of Carolina, which is the next colony northeastward. The air of Carolina has the same motion before the air of Virginia, which lies still more northeastward, and so on northeasterly through Pennsylvania, New York, New England, & c. , quite to Newfoundland. These northeast storms are generally very violent, continue sometimes two or three days, and often do considerable damage in the harbors along the coast. They are attended with thick clouds and rain. What first gave me this idea, was the following circumstance. About twenty years ago, a few more or less, i cannot from my memory be certain, we were to have an eclipse of the moon at Philadelphia, on a Friday evening, about nine o'clock. I intended to observe it, but was prevented By a northeast storm, which came on about seven, with thick clouds as usual, that quite obscured the whole hemisphere. Yet when the post brought us the Boston newspaper, giving an account of the effects of the same storm in those parts, I found the beginning of the eclipse had been well observed there though Boston lies N.E. of Philadelphia about 400 miles. This puzzled me because the storm began with us so soon as to prevent any observation, and being a N. E. storm, I imagined it must have begun rather sooner in places farther to the northeastward than it did in Philadelphia. I therefore mentioned it in a letter to my brother who lived in Boston. And he informed me the storm did not begin with them till near eleven o'clock, so that they had a good observation of the eclipse: And upon comparing all the other accounts I received from the several colonies, of the time of the beginning of the same storm, and, since that of other storms of the same kind, I found the beginning to be always later the farther northeastward. I have not my notes with me here in England, and cannot, from memory, say the proportion of time to distance, but I think it is about an hour to every hundred miles. From thence I formed an idea of the cause of these storms, which I would explain by a familiar instance or two. Suppose a long canal of water stopped at the end by a gate. The water is quite at rest till the gate is open, then it begins to move out through the gate, the water next to that first water moves next, and so on successively, till the water at the head of the canal is in motion, which is last of all. In this case all the water moves indeed towards the gate, but the successive times of beginning motion are the contrary way, viz. from the gate backwards to the head of the canal. Again suppose the air in a chamber at rest, no current in the room till you make a fire in the chimney. Immediately the air in the chimney, being rarefied by the fire, rises, the air next the chimney flows in to supply its place, moving towards the chimney. And, in consequence, the rest of the air successively, quite back to the door. Thus to produce our northeast storms, I suppose some great heat and rarefaction of the air in or about the Gulf of Mexico. The air thence rising has its place supplied by the next more northern, cooler, and therefore denser and heavier, air. That being in motion is followed by the next more northern air, in a successive current, to which current our coast and inland ridge of mountains give the direction of northeast, as they lie N. E. and S. W.

单选题Passages 3 Adam Smith, writing in the 1770s, was the first person to see the importance of the division of labor and to explain part of its advantages. He gives as an example the process by which pins were made in England. "One man draws out the wire; another strengthens it; a third cuts it; a fourth points it; a fifth grinds it at the top to prepare it to receive the head. To make the head requires two or three operations. To put it on is a separate operation, to polish the pins is another. And the important business of making pins is, in this manner, divided into about eighteen operations, which in some factories are all performed by different people, though in others the same man will sometimes perform two or three of them." Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4,800 pins per worker. But if all of them had worked separately and independently without division of labor, none of them could have made twenty pins in a day and perhaps not even one. There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this but he also took it for granted that division of labor is in itself responsible for economic growth and development and that it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new; it only enables people to produce more of what they already have.
