In the journal Science, Professor Starkey calls for ethical guidelines to (1)______ all aspects of robotic technology, not just in the home and workplace, but also on the battlefield, where lethal robots such as the missile-armed Predator drones used in Iraq and Afghanistan are already (2)_____ with lethal effect. The US Future Combat System project aims to use robots as “force multipliers” ,with a single
soldier initiating large-scale ground an (3)______ attacks by a robot droid army. “Robots for care and for war represent just two of many ethically problematic areas that will soon (4)______ from the rapid increase and spreading diversity of robotics appl ications,”
Professor Starkey said ,“Scientists and engineers working in robotics must be mindful of the potential dangers of their work, and public and international discussion is (5)_____ in order to set policy guidelines for ethical and safe application before the guidelines set themselves.”
The call for controls over robots goes back to the 1940s when the science-fiction author Isaac Asimov drew up his famous three laws of (6)_____.The first rule stated that robots must not harm people; the second that they must obey the commands of people provided them does not conflict with the first law; and the third law was that robots must attempt to avoid harming themselves provided this was not in conflict with the two other laws.
Asimov wrote a (7)______ of science fiction series called I, Robot which exploited the issue of machines and morality. He wanted to counter the long history of fictional accounts of dangerous automatons—from the Jewish Golem to Mary Shelly’s Frankenstein—and used his three laws as a literary device to exploit the ethical issues
arising from the human interaction with non-human, intelligent beings. But late 20th--century predictions about the rise of machines (8)______ with superior artificial intelligence have not been realized, although robot scientists have given their mechanical protégés (门客) quasi-intelligent(准智能的) traits such as simple
speech recognition, emotional (9)______ and face recognition.
Professor Starkey believe that even dumb robots need to be controlled.“I’m not sugge sting like Asimov to put ethical rules into robots, but to just to have (10)______ on how robots are used ,”he said.“Current robots are not bright enough even to be called stupid. If I even thought they would be superior in intelligence, I would not have these concerns. They are dumb machines not much brighter than the average washing machine, and that’s the problem.”
Part II . Reading comprehension(20%)
In this part, you will read four passages. 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
Archaeology(考古学) 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 human 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 what 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 and 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 battlefield may “change the course of
history,” but this is equally ephemeral from the archaeologist’s 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 archaeological 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 author’s main purpose in the passage?
A. To point out the importance of recent advances in archaeology.
B. To describe an archaeologist’s 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 meaning 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 mentioned 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 the nineteenth and twentieth centuries
Passage Two
The 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,cars 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 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 determine 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,
certain 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 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 eel’s body are specialized for generating electricity,and the strength of the shock it can deliver corresponds roughly to the length 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 could best be replaced by
_____.
A. feel about
B. move about
C.flicker
D.run away
3. The author mentions all of the following as results of a blackout EXCEPT ______.
A. refrigerated food items may go bad
B. traffic light do not work
C. people must rely on candlelight
D. elevators and escalators do not function
4. Why 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 is the _____ .
A. more beneficial it will be to science
B. more powerful will be its electrical charge
C. easier it will be to find
D. tougher it will be to eat
Passage Three
The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of 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 planet’s atmosphere. The 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 molecules: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 becomes 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 which 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 Earth is that the liquid ______.
A. is affected by changes in pressure
B. has a permanent structure
C. forms a free surface
D. is considerably more common
2. It can be inferred from the passage that the gases of the
Earth’s a tmosphere ate
contained by ______.
A. a closed surface
B. the gravity of the planet
C. the field of space
D. its critical point
3. According to the passage,in the nineteenth century’s some scientists viewed liquidons
and gasons as ______.
A. fluids
B. dissolving particles
C. heavy molecules
D. different types of molecules
4. According to the passage,what happened when the temperature is increased in a 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 the 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 Four
You are in a supermarket deciding what you want to buy.The tomatoes and corn look especially delicious,but wait! Do you stop and wonder if these vegetables are genetically modified?Wouldn’t 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 to 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(除草剂)
plant killing chemicals that farmers use to kill unwanted weeds 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 modified foods are worried about the dangers and they list many.They claim that we don’t 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 modified 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 the describe genes of one organism to another _____.
3. What do the scientists use to modify food crops?
4. Why do some people support genetic modified foods?
5. What are the producers and retailers urged to do by the opponents?
Part III .Translation (20%)
a. Translate the following paragraph into English.
巴斯德通过大量科学实验证明，如果生奶加工时温度超过85?，则其中的营养
物
质和生物活性物质会被大量破坏，但如果低于85?时，则其营养物质和生物活
性物质被保
留，并且有害菌大部分被杀灭，有些有益菌却被存留。所以，将低于85?的消
毒法称作巴
氏消毒法，可以说，这是新鲜牛奶最科学、最好的加工工艺。采用巴氏灭菌法
生产的鲜奶，
其营养价值与新鲜原奶基本相同。但经巴氏消毒后，仍保留了小部分无害或有益、较耐热的
细菌，因此巴氏消毒牛奶要在4?左右的温度下保存，且只能保存3-10天。
b. Translate the following paragraph into Chinese.
Friends you can count on
You spend your time tweeting,friending,liking,poking,and in the few minutes left,cultivating friends in the flesh.Yet sadly,despite all your efforts,you probably have fewer friends than most of your friends
have.But don’t despair--the same is true for almost all of us.Our
friends are typically more popular than we are.Studies of offline social networks show the same trend.It has nothing to do with personalities;it follows from basic arithmetic.This phenomenon has been called the
friendship paradox.Understanding that pattern will help you feel better about some of life’s little
annoyances.

01 Passage 1 Hypnotism (催眠术) is very old. Thousands of years ago people started to use it in Egypt. The use of hypnotism has grown very much since that time. Today, doctors and scientists are in almost every country hypnotize people to help them with their problems. What is hypnotism, and how does it work? Many people think that a hypnotist puts people to sleep. Then he makes the hypnotized people do strange things. This is not what a hypnotist does. Hypnotism is really just a way to relax the mind and body. What are some of the uses of hypnotism? We go to a hypnotist because w e have a problem. The problem makes us unhappy. The hypnotist asks us to think hard about something and relax. When we are relaxed, t he hypnotist gives us some ideas to help us with our problems. Hypnotism can help people to remember things. The police sometimes ask hypnotists to help them. For example, a man sees an accident. He forgets the license number of the car he sees. If he is hypnotized he may remember it. The police can then find the car and catch the driver. People who are hypnotized can also make mistakes or say something that isn't true. People remember what they think they saw. That may not be what really happened. The police don't hypnotize people who do something wrong. Why not? People who are hypnotized may say something that isn't true. A person who has done something bad has a good reason to say something that isn't true. 1. Hypnotist helps people by ____.

We provide the robot with seeing detectors to keep it away from danger. It is powered entirely by the sun. Should we program the robot to be equally active at all times? No. The robot would be using up energy at a time when it was not receiving any. So we would probably program it to cease its activity at night and to wake up at dawn the next morning. According to the evolutionary theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason. The theory does not deny that sleep provides some important restorative functions. It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous. However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us. So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent. The evolutionary theory accounts well for differences in sleep among creatures. Why do cats, for instance, sleep so much, while horses sleep so little? Surely cats do not need five times as much repair and restoration as horses do. But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep. Horses must spend almost all their waking hours eating, because what they eat is very low in energy value. Moreover, they cannot afford to sleep too long or too deeply, because their survival depends on their ability to run away from attackers. 1.The author uses the example of the robot in space exploration to tell us . A) the differences between robots and men B) the reason why men need to sleep C) about the need for robots to save power D) about the danger of men working at night 2.Evolution has programmed man to sleep at night chiefly to help Test Paper of Listening and Pracical Writing NAME_______________ NUMBER ___________ SCORE _________ Part I.
