The simplest layout is accomplished by locating the application in ROM at address 0 in
the memory map.The application can then branch to the real entry point when it executes
its first instruction at the reset vector at address 0x0.But,there are disadvantages
with this layout.ROM is typically narrow (8 or 16 bits) and slow compared to RAM,
requiring more wait states to access it.This slows down the handling of processor
exceptions,especially interrupts,through the vector table.Moreover,if the vector table
is in ROM,it cannot be modified by the code.
Since RAM is normally faster and wider than ROM,it is better for the vector table and
interrupt handlers if the memory at 0x0 is RAM.Although It is necessary that RAM be
located at 0x0 during normal execution,if RAM is located at address 0x0 on power-up,
there is not a valid instruction in the reset vector entry.Therefore,ROM must be located
at 0x0 at power-up to assure that there is a valid reset vector.The changeover from
reset to the normal memory map is normally accomplished by performing the remap
command.

rumor (谣言)is the simplest way of spreading stories — by passing them on from mouth to mouth.but countries in normal times have better sources of news than rumor.they have radio,television and newspapers,etc.in times of stress and confusion,however,rumor emerges and becomes widespread.at such times the different kinds of news are in competition:the press,television,and radio against the mouth-to-mouth stories.especially do rumors spread when war requires ***ship (***,检查) on many important matters.the usual news sources no longer give out enough information.since the people cannot learn through legitimate(正统的) channels all that they are anxious to learn,they pick up "news" wherever they can,and when this happens ,rumor spreads.rumors are often repeated even by those who do not believe the tales.the reason is that the cleverly designed rumor gives expression to something deep in the hearts of certain people — the fears,suspicions,forbidden hopes,or daydreams which they hesitate to voice directly.
36.the best title for this passage would be ____________.
a.rumor and its influence b.rumor and its spreading
c.different kinds of news resources d.how to spread news
37.from the passage we can see that rumors appear and become widespread mostly ____________.
a.in normal times
b.when people have something deep in their hearts
c.in early times when there were no radios,newspapers,etc.
d.in unusual times
38.according to the author,during the wartime the regular sources of news present only ____________.
a.false information b.limited information
c.important information d.unimportant information
39.according to the passage,sometimes people repeat rumors because the rumors ____________.
a.say what they actually wish to say b.are cleverly designed
c.tell what they are anxious to learn d.show their fears and hopes
40.the author suggests that,in times of stress,people are more likely to ____________.
a.become more close-mouthed b.believe newspapers
c.rely on official channels of news resources d.show interest in rumors

The bicycle is one of the simplest yet most useful inventions in the world.The surprising thing is

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads? Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside. The heat-collector is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground. When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store. In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice. 小题1:Which of the following is true according to the first two paragraphs? A．Arian de Bondt got his idea from his boss. B．Large, flat, black surfaces need to be built in cities. C．The Dutch engineer’s system has been widely used. D．Heat can also be collected from asphalt roads. 小题2:For what purpose are the diving pipes used? A．To absorb heat from the sun. B．To store heat for future use. C．To turn solar energy into heat energy. D．To carry heat down below the surface. 小题3:From the last paragraph we can learn that __ A．some pipes have to be re-arranged in winter B．the system can do more than warming up the building C．the exchangers will pick up heat from the street surface D．less heat may be collected in winter than in summer 小题4:What is most likely to be discussed in the paragraph that follows? A．What we shall do if the system goes wrong. B．What we shall do if there are no asphalt roads. C．How the system cools the building in summer. D．How the system collects heat in spring and autumn

Rigid Beam .The simplest way — and probably the first used — is to lay a rigid beam across the stream so that its two ends rest on opposite banks .The rigid beam in this type of bridge may be a shaped wooden beam ,a girder of steel or concrete ,or even a complex truss .The span of a rigid type of bridge can be increased by building intermediate piers and bridging the gaps between the piers with several beams.The materials used for rigid beams must be able to withstand both compression and tension .The double requirement stems from the fact that when a load is placed on a rigid beam ,the beam bends —in spite of its name .As a result of bending the upper part of the beam is compressed and the lower half is stretched .If its compressive strength is too low ,it will buckle ；if its tensile strength is too low ,it will break.

A person riding a bicycle uses very little energy(能源) to make the bicycle move,and there is no pollution(污染) at all when you are riding ,Even so,in developed countries ,most pepole don’t travel to work by bicycle.It is not because the bicycles are expensive or people feel tired if they ride to work.It’s because the number of cars on the roads becomes larger.It certainly becomes more dangerous to ride a bicycle.As a result,more people put their bicycles away and go to work in their cars and ,in this way ,the situation(情形) is made more seriously.Perhaps the best way to make riding safer and more popular is to create paths(开设通道) only for bicycles,and to make it so difficult and expensive for drivers to take their cars into the city that they will go back to using their bicycles.
