The Building of the PyramidsThe oldest stone buildings in the world are the pyramids.【46】 There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the "Step" pyramid and the "Bent" pyramid.Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modem buildings.【47】. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever. 【48】. However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves.【49】. Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly cleat picture of them.One thing is certain: there must have been months of careful planning before they could begin to build.【50】 You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome.A. The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.B. It is practically certain that plans were made for the building of the pyramid because the plans of other large works have fortunately been preserved.C. The first thing they had to do was to choose a suitable place.D. Consequently, we are only able to guess at the methods used.E. Many people were killed while building the pyramids.F. They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.(46)

ESunday is more like Monday than it used to be, Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant (不相关的).A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.The law in almost all states used to require stores to close on Sunday; in most, it no longer does, It used to keep the schools open in all seasons except summer, in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years – but unless we meet the truant officer (学监) ,we may well think that we should go to school due to social custom and parents’ demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes(构成) “overtime” is a matter of legal definition. When we turn the clock forward to start daylight – saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how organize and use time: compulsory education law, overtime law, and daylight – saving law- as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.67. By saying” Sunday is more like Monday than it used to be,” the writer means that __________.A. work time is equal to rest timeB. many people have a day off on Monday,C. it is hard for people to decide when to restD. the line between work time and rest time is unclear
