By about A.D. D.500 the Mound Builder (筑堤人) culture was declining, perhaps because of attacks from other tribes or perhaps because of severe climatic changes that undermined agriculture. To the west, another culture, based on intensive agriculture, was beginning to flourish. Its center was beneath present-day St. Louis, and it radiated out to encompass most of the Mississippi watershed, from Wisconsin to Louisiana and from Oklahoma to Tennessee. Thousands of villages were included in its orbit. By about A.D. D.700 this Mississippian culture, as is known to archaeologists, began to send its influence eastward to transform the life of most of the less technologically advanced woodland tribes. Like the Mound Builders of the Ohio region, these tribes, probably influenced by Meso-American cultures through trade and warfare, built gigantic mounds as burial and ceremonial places. The largest of them, rising in four terraces to a height of one hundred feet, has a rectangular base of nearly fifteen acres, larger than that of the Great Pyramid of Egypt. Built between A.D. D.900 and 1100 this huge earthwork faces the site of a palisaded Indian city which contained more than one hundred small artificial mounds marking burial sites. Spread among them was a vast settlement containing some 30,000 people by current estimations. The finely crafted ornaments and tools recovered at Cahokia, as this center of Mississippian culture is called, include elaborate ceramics, finely sculpted stonework, carefully embossed and engraved copper and mica sheets, and one funeral blanket fashioned from 12, 000 shell beads. They indicate that Cahokia was a true urban center, with clustered housing, markets, and specialists in tool-making,, hide-dressing, potting, jewelry-making, weaving, and salt making.1.

Design of all the new tools and implements is based on careful experiments with electronic instruments. First, a human “guinea pig” is tested using a regular tool. Measurements are taken of the amount of work done, and the buildup of heat in the body. Twisted joints and stretched muscles cannot perform as well, it has been found, as joints and muscles in their normal positions. The same person is then tested again, using a tool designed according to the suggestions made by Dr. Tichauer. All these tests have shown the great improvement of the new designs over the old.One of the electronic instruments used by Dr. Tichauer, the myograph, makes visible through electrical signals the work done by human muscle.Another machine measures any dangerous features of tools, thus proving information upon which to base a new design. One conclusion of tests made with this machine is that a tripod stepladder is more stable and safer to use than one with four legs.This work has attracted the attention of efficiency experts and time-and-motion-study engineer, but its value goes far beyond that. Dr. Tichauer’s first thought is for the health of the tool user. With the repeated use of the same tool all day long on production lines and in other jobs, even light manual work can put a heavy stress on one small area of the body. In time, such stress can cause a disabling disease. Furthermore, muscle fatigue is a serious safety hazard.Efficiency is the by-product of comfort, Dr. Tichauer believes, and his new designs fortraditional tools have proved his point.1. What are involved in the design of a new tool according to the passage?2. From the passage we know that joints and muscles perform best when .3. A “myograph” (Para. A.2, Line 1) is an electronic instrument that .4. It can be inferred from the passage that .5. Dr. Tichauer started his experiments initially to .
It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners in the roads are becoming horrible. Everybody knows that the nicest men become monsters behind the wheels. It is all very well, again to have a tiger in the tank, but to have one in the driver’s seat is another matter altogether. You might tolerate the odd road-hog, the rude and inconsiderate drive, but nowadays the well-mannered motorist is the exception to the rule. Perhaps the situation calls for a “Be kind to other drivers” campaign; otherwise it may get completely out of hand.Road politeness is not only good manner, but good sense, too. It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behavior. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modem modern traffic conditions. But such acknowledgements of politeness are all too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.However, misplaced politeness can also be dangerous. Typical examples are the driver who brakes violently to allow a car to emerge from a side street at some hazard to following traffic, when a few seconds later the road would be clear anyway; or the man who waves a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to. It always amazes me that the highways are not covered with dead bodies of these grannies.A veteran driver, whose manners are faultless, told me it would help if motorists learnt to filter correctly into traffic streams one at a time without causing the total blockages that gives rise to bad temper. Unfortunately, modern motorists can’t even learn to drive, let alone master the subtler aspects of roadmanship. Years ago the experts warned us that the car ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart.1. According to this passage, troubles on the road are mainly caused by         .2. The sentence “You might tolerate the odd road-hog...the rule” (Para. A.1) implies that_________.3. By “good sense”, the writer means          .4. Experts have long pointed out that in the face of car-ownership explosion, ______.5. In the writer’s opinion, ______.
