Guide Dogs
For most dog owners, the expression “work like a dog”doesn’t make much sense. But some dogs happily perform very demanding jobs for much of their life, putting in a full day’s work just like the rest of us. Guide dogs, one of the most familiar sorts of working dog, provide an invaluable service to humans. Every day, they help their masters get from place to place more safely.
What Guide Dogs Do
Guide dogs help blind or visually impaired people get around in the world. In most countries, they are allowed to anyplace where the public is allowed, so they can help their handlers be in any place they might want to go to. To do this, a guide dog must know how to:
·Keep on a direct route, ignoring distractions such as smells, other animals and people
·Maintain a steady pace, to the left and just ahead of the handler
·Stop at all curbs until told to proceed
·Turn left and right, move forward and stop on command
·Recognize and avoid obstacles that the handler won’t be able to fit through (narrow passages and low overheads) ·Stop at the bottom and top of stairs until told to proceed
·Bring the handler to elevator buttons
·Lie quietly when the handler is sitting down
·Help the handler to board and move around buses, subways and other forms of public Vehicles
·Obey a number of verbal commands
Additionally, a guide dog must know to disobey any command that would put the handler in danger. This ability, called selective disobedience, is perhaps the most amazing thing about guide dogs that they can balance obedience with their own assessment of the situation.
This capacity is extremely important at crosswalks, where the handler and dog must work very closely together to navigate the situation safely. Dogs cannot distinguish the color of traffic lights, so the handler must make the decision of when it is safe to proceed across the road. The handler listens to the flow of traffic to figure out when the light has changed and then gives the command “forward”. If there is no danger, the dog proceeds across the road in a straight line. If there are cars approaching, the dog waits until the danger is gone and then follows the forward command.
On the Job and After Hours
Guide dogs enjoy their work immensely, and they get a lot of satisfaction from a job well done, but there is no
room for typical dog fun during the work day. Games, treats and praise cannot distract the dog from helping its handler navigate the course. Even when the handler doesn’t need assistance, a guide dog on the job is trained to ignore distractions and keep still. This is because a guide dog must be able to come to the handler’s workplace or be in public places without creating a disturbance.
When you see a guide dog on the job, it is extremely important that you recognize that it is at work. Petting or talking to the dog breaks its concentration, which impairs the handler’s ability to get around in his or her surroundings. People are very impressed with guide dogs and so we have a natural inclination to praise them, but the best thing you can do to help a guide dog is to leave it alone so that it can pay attention to its surroundings and maintain its focus on its handler. Guiding is very complicated, and it requires a dog’s undivided attention.
When a guide dog gets home at the end of the day, however, it will play and soak up praise just like an ordinary pet. Guide dogs make the distinction between work and play based on their lead harness: When the harness is on, they must stay completely focused; when it comes off, it’s play time. Guide dogs work very hard every day, but they lead extremely happy lives, full of lots of attention and stimulation. Dogs only end up working as guide dogs if they absolutely love the work. In fact, many handlers report that their dogs leap enthusiastically into the harness every morning!
Training
People often raise Golden Retrievers(猎犬),German shepherds or Labradors(拉布拉多猎狗) as candidates of guide dogs. Once a dog is grown up, socialized and well trained, it goes to the guide dog school for evaluation.
In some schools, if a dog is suited for training but not quite ready, it may go back to the puppy(幼犬) raiser for a month or so to mature. If a dog is simply not suited for training, the school will work to place the dog in another line of work, such as tracking, or find it a permanent home, usually offering it to the puppy raiser first. At Guiding Eyes for the Blind, only the top 50 percent of the puppies will stay with the school. So the school places a little over 400 puppies with raisers each year, needing only 200 dogs for the training program. Of that 200,a small percentage will become breeding stock, for Guiding Eyes or another school, and the rest will be considered for the training program.
Training is a rigorous process for both the instructors and the dogs, but it’s also a lot of fun. To make sure the dogs are up to the challenge, most schools test them extensively before beginning the training. The tests are designed to assess the dogs’ self-confidence level, since only extremely confident dogs will be able to deal with the pressure of guiding instruction. If a dog passes the tests, it begins the training program right away.
Different schools have different programs, but typically, training will last four to five months. To make sure the dogs master all the complex guide skills, the instructors have to introduce them to each idea gradually. Once they have introduced what is expected of the dog, training is essentially a matter of rewarding correct performance and punishing incorrect performance. This works with dogs because they are pack animals and have a natural need to please an authority figure. The instructor, or later the handler, is simply stepping into the place of the alpha dog, the leader of the pack.
Unlike ordinary obedience training, guide dog training does not use food as a reward for good performance. This is because a guide dog must be able to work around food without being distracted by it. Instead, instructors use praise or other reward systems to encourage correct performance. The standard means of correction is pulling on the dogs leash, so that it pulls a training collar, giving the dog a slight pinch(捏，掐).Using this basic reward/punishment system, instructors work through the necessary skills for guiding.
Forming a Team
The final stage of a guide dog’s training is learning to work with its new master. Guide dog training schools work very hard to match handlers with guide dogs according to the compatibility of their personalities. A very energetic dog typically does well with a young handler, while an older handler may need an especially careful partner. Schools often have a special gathering to commemorate the time when a new class of guide dogs finally meets their masters. Often, the dogs’puppy raiser attends and meets with the new master as well. This is perhaps the most emotional time in the entire training process.
After this introduction, guide dog instructors typically spend a month helping the new team learn to work
together. Many schools have dormitories for the handlers to stay in during this final stage of training.
If the handler has never used a guide dog before, a lot of the instructors work at this point are actually people training, not dog training. The handler has to learn to read the dogs movements, so he or she knows when the dog is turning or when the dog is stopping for a crosswalk or stairs. Additionally, the handler has to learn all the commands the dog knows, and must get some practice walking with the dog. The dog has to make the transition from obeying the instructor to recognizing the handler as its new master. The handler and the dog spend a lot of this time just getting to know each other, so that they are comfortable enough to work as a team. By the time they graduate from the guide dog school, they can read each others every movement.

Part ⅣReading Comprehension (Reading in Depth) (25 minutes)
Section A
Directions:In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words on Answer Sheet 2. Questions 47 to 51 are based on the following passage.
Women often complain that dating is like a cattle market, and a paper just published in Biology Letters by Thomas Pollet and Daniel Nettle of Newcastle University, in England, suggests they are right. They have little cause for complaint, however, because the paper also suggests that in this particular market, it is women who are the buyers.
Mr. Pollet and Dr. Nettle were looking for evidence to support the contention that women choose men of high status and resources, as well as good looks. That may sound common sense, but it was often denied by social scientists until a group of researchers who called themselves evolutionary psychologists started investigating the matter two decades ago. Since then, a series of experiments in laboratories have supported the contention. But as all zoologists know, experiments can only tell you so much. Eventually, you have to look at natural populations.
And that is what Mr. Pollet and Dr. Nettle have done. They have examined data from the 1910 census of the United States of America and discovered that marriage is, indeed, a market. Moreover, as in any market, a scarcity of buyers means the sellers have to have particularly attractive goods on offer if they are to make the exchange.
The advantage of picking 1910 was that America had not yet settled down, demographically(人口统计学方面) speaking. Though the long-colonized eastern states had a sex ratio of one man to one woman, or thereabouts, in the rest of the country the old adage(格言，谚语)“go west, young man” had resulted in a surplus of males. Mr. Pollet and Dr. Nettle were thus able to see just how picky women are, given the chance.
Rather than looking at the whole census, the two researchers relied on a sample of one person in 250.They then assigned the men in the sample a socioeconomic status score between zero and 96, on a scale drawn up in 1950.They showed that in states where the sexes were equal in number, 56% of low status men were married by the age of 30, while 60% of high status men were. As the men went west, then, so did their marriage opportunities.
47. A paper published in Biology Letters agreed with women that .
48. What is the contention which is often denied by social scientists?

50. In the market of marriage, a scarcity of buyers means sellers have to to make the exchange.

Section B
Directions:There are 2 passages in this section. Each passage is followed by some questions or unfinished
statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
Passage one
Questions 52 to 56 are based on the following passage.
With the possible exception of equal rights, perhaps the most controversial issue across the United States today is the death penalty. Many argue that it is an effective deterrent (威慑) to murder, while others maintain there is no convincing evidence that the death penalty reduces the number of murders.
The principal argument advanced by those opposed to the death penalty, basically, is that it is cruel and inhuman punishment, which is the mark of a brutal society, and finally that it is of questionable effectiveness as a deterrent to crime anyway.
In our opinion, the death penalty is a necessary evil. Throughout recorded history there have always been those extreme individuals in every society who were capable of terribly violent crimes such as murder. But some are more extreme than others.
For example, it is one thing to take the life of another in a fit of blind rage, but quite another to coldly plot and carry out the murder of one or more people in the style of a butcher. Thus, murder, like all other crimes, is a matter of relative degree. While it could be argued with some conviction that the criminal in the first instance should be merely isolated from society, such should not be the fate of the latter type murderer.
The value of the death penalty as a deterrent to crime may be open to debate. But the overwhelming majority of citizens believe that the death penalty protects them. Their belief is reinforced by evidence which shows that the death penalty deters murder. For example, from 1954 to 1963, when the death penalty was consistently imposed in California, the murder rate remained between three and four murders for each 100,000 population. Since 1964 the death penalty has been imposed only once, and the murder rate has risen to 10.4 murders for each 100,000 population. The sharp climb in the state’s murder rate, which began when executions stopped, is no coincidence. It is convincing evidence that the death penalty does deter many murderers. If the bill reestablishing the death penalty is vetoed, innocent people will be murdered—some whose lives may have been saved if the death penalty were in effect. This is literally a life or death matter. The lives of thousands of innocent people must be protected.
52. The principal purpose of this passage is to .
A) speak for the majority B) initiate a veto
C) criticize the government D) argue for the value of the death penalty
53. The author’s response to those who urge the death penalty for all is likely to be .
A) negative B) friendly C) supportive D) hostile
54. According to the Paragraph 4, it can be inferred that .
A) the death penalty is the most controversial issue in the United States today
B) the second type of murderers should be sentenced to death
C) the veto of the bill reestablishing the death penalty is of little importance
D) the value of the death penalty as a deterrent to crime is not to be debated
55. The passage attempts to establish a relationship between .
A) the murder rate and the imposition of the death penalty
B) the effects of execution and the effects of isolation
C) the importance of equal rights and that of the death penalty
D) executions and murders
56. The author’s attitude towards “death penalty” is .
A) opposing B) supporting C) neutral D) sarcastic
Passage Two
Questions 57 to 61 are based on the following passage.
One positive consequence of our current national crisis may be at least a temporary shadow in Hollywood’s culture of violence. Fearful of offending audiences in the wake of the terrorist attack, some moviemakers have
postponed the release of film with terrorist themes. Television writers are delaying scripts with warlike and terrorist scenarios(剧本提纲).It is probably good thinking. My local video store tells me nobody is checking out “disaster”movies. Says the manager, “Currently, people want comedy. They want an escape from stories about violence and terrorism.” Similarly, in the music business, there’s a run on patriotic and inspirational tapes and CDs.
According to The New York Times, the self scrutiny among these czars (特权人物) of mass-entertainment taste is unprecedented in scale, sweeping aside hundreds of millions of dollars in projects that no longer seem appropriate.
A reasonable concern is that this might be a short term phenomenon. Once life returns to something more normal, will Hollywood return to its bad old ways? The Times offers a glimmer of hope. The industry’s titans(巨头),it suggests, are struggling with much more difficulties, long range questions of what the public will want once the initial shock from the terrorist attacks wears off. Many in the industry admit they do not know where the boundaries of taste and consumer tolerance now lie.
This is an opportunity for some of us to suggest to Hollywood where that boundary of consumer tolerance is, especially those of us who have not yet convinced Hollywood to cease its descent into ever lower of the dumbness of our young.
The nonprofit Parents Television Council, which monitors the quality of TV programming, says in its latest report that today’s TV shows are more laced than ever with vulgarities, sexual immorality, crudities, violence, and foul language. The traditional family hour between 8p.m.and 9p.m., when the networks used to offer programs for the entire family, has disappeared. The problem looks like it will get worse.
That certainly looked to be the case before the Sept.11th assault. One pre attack New York Times story reported that TV producers were crusading (讨伐) for scripts that include every crude word imaginable. The struggles between net-work censors and producers, according to the report, were “growing more intense”. Producers like Aaron Sorkin of “The West Wing” planned to keep pushing hard. He was quoted as saying,“There’s absolutely no reason why we can’t use the language of adulthood in programs that are about adults”.
My guess is that a lot of adults don’t use the language Mr. Sorkin wants to use, and don’t enjoy having their children hear it. At this moment of crisis in our nation’s history, thought has become more thoughtful, prayerful, and spiritual. It may be the time to tell the entertainment industry that we want not a temporary pause in the flow of tastelessness, but a long term clean-up.
57. Some filmmakers hesitate to release new films with violent content because .
A) they want to show themselves to be patriots
B) they are afraid such films may anger audiences
C) films with violence in them are no longer popu1ar
D) films with terrorist themes are reflections on violence.
58. The “self-scrutiny” in the second paragraph refers to filmmakers attempt to .
A) produce appropriate films with no violent content for the audiences
B) prevent themselves from slipping into their old bad ways
C) understand to what extent their films have contributed to the national crisis
D) find out where the boundaries of taste and consumer tolerance lie
59. The author thinks that it is time for the general audience to .
A) tell filmmakers where the boundaries of their taste lie
B) point out to Hollywood how bad their films are
C) accuse the filmmakers of desensitizing their children
D) ask filmmakers to make films that reflect traditional family life
60. Which of the following statements is TRUE about Aaron Sorkin?
A) He is strongly against using crude language in films.
B) He starts the struggles between network censors and producer.
C) He insists no restraint be set to the language used in films.
D) He believes that it is time to clean up the entertainment industry.。
