CATS ON THE COUCH
Nicholas Bagnall reviews Cat Confidential by Vicky Halls
Vicky Halls is a ‘cat behaviour counsellor’. The idea of such a person would have been incomprehensible to those brought up on Rudyard Kipling, who plainly didn’t think much of cats and thought they could manage perfectly well without humans. Cats in those days were generally thought effeminate anyway, not like gruff and manly dogs. We know better now, yet it’s still surprising how little we understand them.
Vicky Halls has often been called in to sort out some wretched animal that’s making messes all over the house or obnoxiously wetting the furniture (the commonest symptom of anxiety or distress), and has discovered that either it is frightened of another cat in the household, or is missing a dead one, or is jealous of other cats or of humans, or it can’t stand the wood chips in its litter tray, while its doting owners have had no idea what has been going on in its unhappy head.
Sometimes the problem is obvious enough, as in the case of a cat called Chester whose owner let him sleep with her when her husband was away, and who then became so jealous that he actively and sometimes painfully came between husband and wife when all three were in bed. Most of us would have got rid of the cat, but instead they summoned Ms Halls who eventually broke up this absurd triangle by arranging alternative pleasures for Chester, such as a comfy bed of his own and more time outdoors.
Our own two cats are lucky enough to be able to come and go as they please, and I feel sorry for the ones that can never leave the house or flat. No wonder some of them get a touch neurotic. Ms Halls prescribes a range of devices to distract the indoor cat, perhaps a few cardboard boxes to hide in, or a high shelf to sit on with a view through another window. And she’s full of common sense tips. (Don’t put the litter tray near the food bowl.)
Her views on cat flaps are more contentious. She thinks of a cat flap as a swing door. How would you like to have a front door like that, she asks, with no defence against thieves and invaders? No wonder your cat you like starts spraying all over the place. (Spraying is also a cat’s way of registering its presence and marking its territory.) If you must have a flap, try locking it shut at night. This seems to me rather hard on the cat, a semi- nocturnal beast.
Ms Halls is pleasantly free of mawkishness. She realises that for many people, particularly if they live alone, a cat becomes the focus of their love, and she herself quite plainly adores them, describing the looks and foibles of individual specimens with touching precision; but she manages to keep her emotional distance and is an excellent story-teller. Only towards the end, when offering bereaved owners some grievance counselling, does she become too sentimental, too anthropomorphic if you like, for my taste. But then cats have always evoked strong emotions.
Question 22. What can we infer about cat behaviour counsellors?
A. They are a relatively new breed of professionals.
B. People felt that they were strange in the past.
C. They believe that cats shouldn’t be domesticated.
D. They claim dogs are generally viewed in a more favourable way than cats.

1 2 3 4 5 6 7 8 9 10 11 12 | Without a time machine, it’s impossible to say for sure how things will turn up, but in my own – somewhat pessimistic – view of the future, I see a world where much of the earth’s flora and fauna will have become extinct – a world with pollution skies and seas. Thanks to climate change, icebergs will have melted and coastal waters will have raised. A soaring human population will live in overcrowded cities further inland, the superrich will have everything they need, while three quarters of the global population will face starvation. And the population will continue to increase. In the western world, medical advances will helped to eradicate most diseases and people will live much longer. However, societies will struggle to support this ageing population, many of them will be forced to keep working until they are well into their nineties. Medical intervention will have made it possible for most fertile couples to have children, while the super-rich will be able to ‘design’ their babies, and select the qualities they would like them to have. |

E. Steve, a personal trainer, used his work to mask his secondary addiction.
F. The thrill from the exercise is the thing, the drug-like feelings brought about by the activity are what addicts want.
G. With a negative addiction, on the other hand, exercise overrides everything.
KICKING THE HABIT
The term ‘exercise addiction’ was coined in 1976 by Dr William Glasser when he was studying long-distance runners. He noticed that many of them experienced low moods when they couldn’t train, and he came to differentiate between positive and negative addictions: a positive addiction involves a love of the activity, and the exercise is scheduled around other everyday activities. You run your running schedule, for example, rather than it running you, and an enforced day off isn’t the end of the world. The results are increased feelings of physical and psychological wellbeing. (56) ____G – With a negative addiction, on the other hand, exercise overrides everything____. Relationships and work suffer, a day away from the gym causes distress, and health can decline as overtraining leads to injury and illness.
Two types of negative exercise addiction have since been defined. Secondary addiction is probably the most common, where the compulsion to exercise is driven by a need to control and change one’s body shape, and is often accompanied by an eating disorder. (57)_E – Steve, a personal trainer, used his work to mask his secondary addiction___ ‘Whatever workout my client was doing, I’d do it, too, alongside them, supposedly to motivate them, but in fact it was to keep my weight down. In total, I was doing several hours of cardio every day, and I didn’t actually enjoy the exercise. I hated the feeling of not having the perfect body even more, though.”
With Primary addiction, body image isn’t so central. (58) ____F – The thrill from the exercise is the thing, the drug-like feelings brought about by the activity are what addicts want _____ It works like this: when we exercise strenuously, we activate our sympathetic nervous system, causing a rise in the concentration of serotonin and other chemicals in the brain which make us feel happy.
At the same time, the body produces endorphins which shut down pain signals reaching the brain. (59) ___A – Half an hour of intense aerobic exercise can produce five times the amount you’d have if you were sitting down ___ Add all these together, and you have a recipe for mild euphoria. Unfortunately, just as the body’s tolerance of drugs increases, so it is with endorphins: more are required to produce the same thrill, so the exercise intensity has to be increased. (60) _____C – It may be, though, that the thrill can never quite compare with that achieved by taking drugs____. Tony, who took drugs daily for almost a decade, then took to running half-marathons. He admits that getting the kick got harder. He said he’d lie awake at night thinking about the next day’s session. It still wasn’t as good as the drugs he was on before. Sports and exercise psychologist Paul Russell has encountered many people like Tony. ‘Exercise addiction tends to be a more temporary addiction, marking time before the person returns to the basic ones, like drugs. (61) __D – People become addicted to something because there’s an underlying unhappiness___ If they haven’t sorted out the reasons for this state, via counselling for example, they’ll have to direct that need to something else.”
For questions 62-75, read the following passage and do the tasks that follow.
THE DEVELOPMENT OF ‘ARTIFICIAL LIFE’
They come into a world where they must struggle to survive. Over many generations, they evolve. But are they alive? Of course, you might say. But we’re not talking about amoebae, ants or alligators. We’re talking about computer programs.
‘Artificial life’ exists only within PCs and more powerful computers, but existence in its electronic universe parallels many elements of life in the biological world. Some programs flock like birds. Others organise like bees. Some mutate swiftly from chaotic hordes to complex, stable populations in a process eerily akin to Darwinian evolution.
As a group, artificial life programs represent the most exciting work on the edge of computer research. Study of artificial life holds promise for new ways of solving complex problems and fresh opportunities to model biology and society. Perhaps, far in the future, such research will yield the ability to blueprint living organisms.
The basics behind artificial life are surprisingly simple. The programs follow a few simple rules, applying them with a speed and persistence that’s possible only inside a computer. When many such programs are run simultaneously, amazingly complex patterns can emerge. In many cases, these patterns are spooky replications of natural behaviours. Programs ‘band together’ against common enemies and devise new ways of surviving when their environment changes. These results aren’t surprising when you consider that biological life itself consists of nothing more than variations on four simple rules: the four compounds that constitute DNA, the building block of all genes and therefore all life. In artificial life, computer instructions take the place DNA code.
The father of modern artificial life research, Christopher Langton of the Los Alamos National Laboratory in the U.S., sees his work this way: ‘For us, artificial life is the study of man-made systems that exhibit behaviour characteristics of natural living systems. We’re attempting to abstract logical forms of life, not matter. We can obtain some of the same dynamics as life, albeit with different materials.”
In the early 1980s, Langton took up the study of self-replicating programs begun more than 30 years earlier by John von Neumann, a Hungarian mathematician whose theories contributed to the development of the programmable digital computer. An example of how programs mimic biology can be found in cellular automata-literally, ‘cell-like machines’: structures that arise from tiny programs that each display a seemingly independent existence based on a few simple rules. Analogies between programs like this and actual life forms are inevitable. When simulated organisms cluster together, leaving rectilinear tracks on the screen, researchers call them ‘ants’. When they do this in a three-dimensional model, they’re called ‘bees”. And perhaps the most disturbing analogy with biological life can be found in computer ‘viruses’, self- replicating programs that display purposeful behaviour and tolerate perturbations in their environment. Although some scientists regard viruses as the first programs capable of existing without the wilful cooperation of humans, the fact is that without humans to design them, they wouldn’t exist at all.
Still, some of the work demonstrated at a recent gathering of the artificial life research clan causes the biological heart to flutter.
‘During five intense days’, said Langton, ‘we saw a wide variety of models of living systems, including mathematical models for the origins of life, self reproducing automata, computer programs using the mechanisms of Darwinian evolution to produce co-adapted ecosystems, simulations of flocking birds and schooling fish, the growth and development of artificial plants, and much, much more.’
Craig Reynolds of Symbolics demonstrated his ‘boids’, computer-animated, bird-shaped creatures that flock like real birds. Reynolds programmed the ‘boids’ to follow three simple rules: they maintain a minimum distance from the nearest object; they match velocity with the nearby flock; and they fly toward the greatest concentration of the flock.
The resulting flocking behaviour is shockingly real.’Ants’, the creation of David Jefferson and Robert Collins, also appeared. Colonies of these randomly generated creatures have developed the ability to navigate electronic mazes and search for symbols that represent food.
Independent programmer John Nagle argued that the next generation of supercomputers should challenge researchers to create ‘squirrels’, computer models with the intelligence level of a biological rodent with one gram of brain mass.
Langton’s contribution, ‘Computation at the edge of chaos’, was one of the most unusual presentations. Biologists maintain that life began in a spontaneous outburst of activity that occurred when Earth’s environment reached critical thresholds of heat, atmosphere and chemical composition. A few variations on any of these variables would have altered the course of the planet into either chaos or barrenness.
Langton’s presentation was based on a computer model demonstrating similar principles. Changing a parameter in the model acts like changing the temperature of a computer-generated petri dish of single-cell creatures. When this variable passes a critical threshold, the colonies of Langton’s artificial life programs neither freeze nor evaporate but settle into recurring patterns conducive to the orderly transmission of information. ‘At one end, activity freezes; at the other end, it’s too volatile,’ notes Langton. As a result, he wonders whether ‘computation may emerge spontaneously and come to dominate the dynamics of physical systems’ much as life has. In fact, Langton speculates that life itself may have started as a chance computation on the cusp of liquid and gaseous states.
And which of these simple programs, we might wonder, will someday hoist itself out of the electronic soup (as creatures once dragged themselves out of ancient seas), look around at the new surroundings and wonder who made it all happen? To Langton, that’s not an odd image. In the scale of geologic time,’ he observes, ‘this may be the end of an era in our little part of the universe. We’re not the end point of evolution. Some artificial life form we create may be the next step on the evolutionary ladder.’
“We haven’t really needed a definition of “life” before,” he says. “We were it. But the computational structures that we’re looking at do exhibit a lot of the criteria that biologists use for describing life: they’re complex, purpose-driven structures. They reproduce. They use the energy resources of their host for their own ends. Are real viruses alive? We’re not so sure now. There’s a grey area in here where our definitions just don’t work.’
Apart from spawning sci-fi speculations, artificial life has begun to show commercial promise. Danny Hillis, the founder of the Thinking Machines Corporation in the U.S., for instance, has unveiled a program that follows a process similar to Darwinian evolution to optimise the problem-solving efficiency of software – a method that could lead to continuously self-improving programs.

Complete the following summary of part of the passage by choosing the correct word or phrase from the box below and writing its letter in the numbered space on the answer sheet. There are more word and phrases than you will need.
A Darwinian theories of evolution B DNA codes C theories of artificial life D computer instructions E Christopher Langton | F computer-generated “life” G the end point of evolution H society I biological life forms J groups lacking organisation |
The reading passage discusses possible similarities between ‘real’ or biological life and (0) ____F______ . In biological life, (62) ___B__ are the basis of life and behaviour. Recently, computer researchers have begun to study so-called ‘artificial life’, computer-generated graphics in which the on-screen images seem to imitate the behaviour of (63) ___I______. In these programs (64) ___D_____ take the place of DNA codes.
These computer-generated ‘life forms’ include some which behave like insects and birds and others which mutate from (65) ___J____ into highly organised, complex populations. The researchers inevitably draw parallels with (66) ___F___ and compare them to actual life forms, even to the extent of giving them names like ants and bees.
Eventually, the study of ‘artificial life’ may allow researchers to re-evaluate models of (67) ___H___ and biology.

(62) biological life itself consists of nothing more than variations on four simple rules: the four compounds that constitute DNA, the building block of all genes and therefore all life.
(63) An example of how programs mimic biology can be found in cellular automata-literally, ‘cell-like machines’
(64) In artificial life, computer instructions take the place DNA code.
(65) Some mutate swiftly from chaotic hordes to complex, stable populations in a process eerily akin to Darwinian evolution.
(66) In the early 1980s, Langton took up the study of self-replicating programs …. An example of how programs mimic biology can be found in cellular automata-literally, ‘cell-like machines’… Analogies between programs like this and actual life forms are inevitable. When simulated organisms cluster together, leaving rectilinear tracks on the screen, researchers call them ‘ants’. When they do this in a three-dimensional model, they’re called ‘bees”.
(67) Study of artificial life holds promise for new ways of solving complex problems and fresh opportunities to model biology and society.

70. Programs that reproduce themselves and seem to have a purpose. -> viruses
Xem giải thích
And perhaps the most disturbing analogy with biological life can be found in computer ‘viruses’, self- replicating programs that display purposeful behaviour and tolerate perturbations in their environment.
QUESTIONS 71-75
Read the statements below. In boxes 71-75 on the answer sheet, write
TRUE if the statement is true
FALSE if the statement is false
NOT GIVEN if the information is not given in the passage
71. Computer viruses may be the ‘artificial life’ programs that most closely resemble biological life, but they ultimately depend on humans. T
Xem giải thích
=> Although some scientists regard viruses as the first programs capable of existing without the wilful cooperation of humans, the fact is that without humans to design them, they wouldn’t exist at all. Still, some of the work demonstrated at a recent gathering of the artificial life research clan causes the biological heart to flutter.
72. The following generation of ‘artificial life’ programs may be ‘squirrels’ which would be self-replicating. NG
Xem giải thích
=> Independent programmer John Nagle argued that the next generation of supercomputers should challenge researchers to create ‘squirrels’, computer models with the intelligence level of a biological rodent with one gram of brain mass.
73. Langton speculates that life started as a chance computation and goes on to say that one day computations in computers may generate life. T
Xem giải thích
=> Langton speculates that life itself may have started as a chance computation on the cusp of liquid and gaseous states…. Some artificial life form we create may be the next step on the evolutionary ladder.’
74. His work in ‘artificial life’ systems has led Langton to offer a new definition of ‘life’ itself. F
Xem giải thích
Đáp án: F
=> “We haven’t really needed a definition of “life” before,” he says. …… We’re not so sure now. There’s a grey area in here where our definitions just don’t work.’
75. Research into ‘artificial life’ programs, resembling as it does science fiction rather than fact, will generally speaking, not be useful until far into the future. F

Đáp án: F
=> Apart from spawning sci-fi speculations, artificial life has begun to show commercial promise.
