You are required to choose the best answer to each question according to the passage and then mark your answer on the Answer Sheet by blacking the letter in the brackets.Passage One Archaeolo

18、gy(考古學) is a source of history, not just a humble auxiliary discipline. Archaeological data are historical documents in their own right, not mere illustrations to written texts. Just as much as any other historian, an archaeologist studies and tries to reconstitute the process that has created the h

19、uman world in which we live-and us ourselves in so far as we are each creatures of our age and social environment. Archaeological data are all changed in the material world resulting from human action or, more succinctly, the fossilized results of human behavior. The total sum of these constitute wh

20、at may be called the archaeological record. This record exhibits peculiarities and deficiencies the consequences of which produce a rather superficial contract between archaeological history and the more familiar kind based upon written records. Not all human behavior fossilizes. The words I utter a

21、nd you hear as vibrations in the air are certainly human changes in the material world and may be of great historical significance. Yet they have no sort of trace in the archaeological records unless they are captured by a Dictaphone or written down by a clerk. The movement of troops on the battlefi

22、eld may “change the course of history,” but this is equally ephemeral from the archaeologists standpoint. What is perhaps worse, most organic material are perishable. Everything made of wood, hide, wool, linen, grass, hair, and similar material conditions. In a relatively brief period the archaeolog

23、ical record is reduced to more scraps of stone, bone, glass, metal, and earthenware. Still modern archaeology, by applying appropriate techniques and comparative methods, aided by a few lucky finds from peat bogs deserts, and frozen soil is able to fill a good deal of the gap. 1. What is the authors

24、 main purpose in the passage? A. To point out the importance of recent advances in archaeology. B. To describe an archaeologists education. C. To explain how archaeology is a source of history. D. To encourage more people to become archaeologists. 2. The word “succinctly” in line 6 is closest in mea

25、ning to _. A. concisely B. briefly C. clearly D. appropriately 3. According to the passage, the archaeological record consists of _. A. spoken words of great historical significance B. the fossilized results of human activity C. organic materials D. ephemeral ideas 4. Which of the following is NOT m

26、entioned as an example of an organic material? A. stone B. wool C. grass D. hair 5. The paragraph following the passage most probably discusses _. A. techniques for recording oral histories B. certain battlefield excavation methods C. some specific archaeological discoveries D. building materials of

27、 the nineteenth and twentieth centuriesPassage TwoThe modern age is age of electricity. People are so used to electric lights,radio,televisions, and televisions that it is hard to imagine what life would be like without them. When there is a power failure,people grope about in flicking candlelight,c

28、ars hesitate in the streets because there are no traffic light to guide them,and food spoils in silent refrigerators.Yet,people began to understand how electricity works only a little more than two centuries ago.Nature has apparently been experimenting in this field for millions of years.Scientists

29、are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.All living cells send out tiny pulses of electricity.As the heart beats,it sends out pulses of recorded,they form an electroencephalogram,which a doctor can study to deter

30、mine how well the heart is working.The brain,too,sends out brain waves of electricity,which can be recorded in an electroencephalogram.The electric currents generated by most living cells are extremely small-often so small that sensitive instruments are needed to record them. But in some animals, ce

31、rtain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all.When large numbers of these cells are linked together,the effects can be astonishing.The electric eel is an amazing storage battery.It can send a jolt of as much as eight hundred volts

32、 of electricity through the water in which it lives (An electric house current is only one hundred twenty volts).As many as four-fifth of all the cells in the electric eels body are specialized for generating electricity,and the strength of the shock it can deliver corresponds roughly to the length

33、of its body.1. What is the main idea of the passage?A. Electric eels are potentially dangerous.B. Biology and electricity appear to be closely related.C. People would be at a loss without electricity.D. Scientists still have much to discover about electricity.2. The phrase “grope about”in line 3 cou

34、ld best be replaced by _. A. feel about B. move about C.flicker D.run away3. The author mentions all of the following as results of a blackout EXCEPT _.A. refrigerated food items may go badB. traffic light do not workC. people must rely on candlelightD. elevators and escalators do not function4. Why

35、 does the author mention electric eels?A. To warn the reader to stay away from them.B. To compare their voltage to that used in houses.C. To give an example of a living electrical generator.D. To describe a new source of electrical power.5. It can be inferred from the passage that the longer an eel

36、is the _ .A. more beneficial it will be to scienceB. more powerful will be its electrical chargeC. easier it will be to findD. tougher it will be to eatPassage ThreeThe difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of

37、the Earth.A liquid can be kept in an open container and fills it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the space available,it must therefor be kept in a closed container or held by a gravitational field,as in the case of a planets atmosphere. The

38、 distinction was a prominent feature of early theories describing the phase of matter.In the nineteenth century,for example, one theory maintained that a liquid could be “dissolved” in a vapor without losing its identity,and another theory held that the two phases are made up of different kids of mo

39、lecules:liquidons and gasons. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure and they both flow readily.They are fluids.The fundamental similarity of liquids and gases be

40、comes clearly apparent when the temperature and pressure are raised somewhat. Suppose a closed container partially filled with a liquid is heated. The liquid expands, or in other words becomes less dense as the evaporated molecules are added to it. The combination of temperature and pressure at whic

41、h the densities become equal is called the critical point.Above the critical point the liquid and the gas can no longer be distinguished;there is single,undifferentiated fluid phase of uniform density.1. According to the passage,the difference between a liquid and a gas under normal condition on Ear

42、th is that the liquid _.A. is affected by changes in pressureB. has a permanent structureC. forms a free surfaceD. is considerably more common2. It can be inferred from the passage that the gases of the Earths atmosphere ate contained by _.A. a closed surface B. the gravity of the planet C. the fiel

43、d of space D. its critical point3. According to the passage,in the nineteenth centurys some scientists viewed liquidons and gasons as _.A. fluids B. dissolving particlesC. heavy molecules D. different types of molecules4. According to the passage,what happened when the temperature is increased in a

44、closed container holding a liquid?A. the liquid and gas phases become more similar.B. the liquid and gas become less dense.C. the container expands.D. the liquid evaporates out of the container.5. According to the passage, which of the following is the best definition of the critical point?A. When t

45、he temperature and the pressure are raised.B. When the densities of the two phases are equal.C. When the pressure and the temperature are combined.D. When the container explodes.Passage FourYou are in a supermarket deciding what you want to buy.The tomatoes and corn look especially delicious,but wai

46、t! Do you stop and wonder if these vegetables are genetically modified?Wouldnt you want to know before you bought them? Should they be labeled so that have the right to choose? What are genetically modified foods? Genes are the blueprints.Scientists can transfer the desirable genes of one organism t

47、o another,altering its genetic make-up.Scientists now are routinely using genes from bacteria,viruses,insects,fish,and animals to modify food crops.Supporters of genetically modified foods want crops that are resistant to herbicides(除草劑) plant killing chemicals that farmers use to kill unwanted weed

48、s and plants.Supporters also say that these new genetically altered crops,such as corn,potatoes,soy beans are more resistant to certain bacteria,viruses and insects.Other claim that in the future,scientists will develop foods that are nutritious and able to prevent diseases.Opponents of genetically

49、modified foods are worried about the dangers and they list many.They claim that we dont know what the long-term effects of producing genetically modified foods will be,and once changes are made in the genetic structure of organisms,they cnnot be reversed.At the very last,opponents of genetically mod

50、ified foods want producers and retailers to clearly mark products that contain genetically modified ingredients.Will all the technology result in better crops and healthier food?Or is there a risk to humans and environment that should not be ignored?Questions:1. What is the passage mainly talking about?2. Scientists can transfer
